Full textAbstract:
AbstractAnglicanism in New Zealand can be traced back to the beginning of New Zealand settlement itself. From its earliest days, the Anglican Church has deliberately set out to bridge divides between New Zealand’s indigenous population, Māori, and Europeans, though with mixed success. This article will illustrate that, even with this experience in bicultural engagement, the Anglican Church has not adapted well to the super-diverse multicultural New Zealand of the twenty-first century. Census data reveal that the Anglican Church has had a precipitous drop in numbers, and has a demographic profile that is much older and whiter than the general New Zealand, let alone Christian, population. This poses significant challenges for its ongoing sustainability. Given the common experience of super-diversity with other Western countries, this article provides a case study and a cautionary tale about the challenges and realities of the Anglican Church adjusting to a new multicultural society.

Full textAbstract:
New Zealand has much of real quality to be proud of in special education. On numerous international surveys of education, New Zealand schools continue to rank highly - especially with respect to reading and written language, and were such surveys to focus on special educational matters, my guess is that the picture would be equally positive. There are very real difficulties in developing special educational provisions for a country with New Zealand’s geographical characteristics. New Zealand has a relatively small total population, which is scattered widely across a rather large and geographically well separated area, and these factors make for real problems in providing for children with difficulties which occur infrequently - as do most conditions associated with exceptionality and special education.

Full textAbstract:
Objective Suicide is a significant public health problem in New Zealand, with the youth suicide rate being one of the highest among developed countries. Increased suicide rates in recent years suggest that the evidence base and research priorities for New Zealand suicide prevention need to be reassessed. To inform policy development, the aim of the present study was to evaluate all peer-reviewed New Zealand published suicide research and major grant allocations from 2006 to 2016. Methods The methodology duplicated a recent Australian review of suicide prevention research and funding. Publications and grant funding allocations were assessed independently. Key research databases were searched in April 2016 for all suicide-related publications. Identified papers were then classified by research type, population focus and type of self-injurious behaviour. Citation indices were obtained for each publication. Annual reports, newsletters and summary data from four major New Zealand funding bodies (the Health Research Council of New Zealand, Marsden Fund, Lottery Health Research and the Ministry of Health) were reviewed for funding allocations. Identified grants were coded for type of project, type of self-injurious behaviour and target population. Descriptive analyses were performed. Results In all, 104 published articles and 27 grants met review criteria. Total funding was NZ$12 677 261.62. Most published articles were epidemiological in nature and the most common type of grant was for an intervention. Conclusions In the past decade, a substantial number of articles has been published and significant funding was invested in New Zealand’s suicide research. The present review suggests that future research investments should focus on effective translation of research findings into suicide prevention programs. Several pragmatic recommendations are proposed to help improve the evidence base and reduce New Zealand’s suicide rates. What is known about the topic? Suicide prevention continues to be a national public health priority for New Zealand. Although much is known about the prevalence of suicidal behaviours in New Zealand, less is known about how well suicide research has addressed prevention priorities and specific target populations. Australian research found that research funding and publications were dominated by epidemiological studies rather than evaluation or intervention studies. It is yet to be determined whether these research and funding trends also apply for New Zealand. What does this paper add? This study examined all peer-reviewed and published suicide research and all major suicide prevention projects that have been funded in New Zealand between 2006 and 2016. The purpose of the review was to summarise the evidence base, evaluate funding and determine the ability of the evidence base to inform policy development. The findings demonstrate that the New Zealand research trends are similar to those found in Australia, with most studies being epidemiological and few representative of interventions. What are the implications for practitioners? This review highlights that there were few intervention and evaluation studies. Partnerships between practitioners and/or community organisations implementing interventions and researchers to systematically evaluate existing interventions and develop new evidence-based interventions would help improve the evidence base for New Zealand suicide prevention.

Full textAbstract:
The Citizenship Amendment Act 2005 removed the traditional common law rule that a person born in New Zealand was, just for that reason, a New Zealand citizen. It required that the person have a parent who was a New Zealand citizen or permanent resident at that time. The change is often said to have been made to prevent transient immigrants having New Zealand citizen children in order to remain in the country, after the Supreme Court's decision in the Ding and Ye line of cases reputedly confirmed that foreign parents did thus obtain that right. This article discusses the misconceptions surrounding the loss of full birthright citizenship, the background of contemporary citizenship law in the common law world and the potential effects of the recent change on migrant communities and on New Zealand's existing population.

Full textAbstract:
The sea urchin Centrostephanus rodgersii has increased its range in Eastern Australia resulting in important ecological changes. C. rodgersii may also have expanded its distribution range to northern New Zealand in the last five to six decades, although little is known about this process and of the biology of the species in New Zealand. We investigated morphometrics as well as growth using two techniques (growth line count in genital plates and tag–recapture using the fluorescent marker tetracycline). These methods allowed modelling of size at age of C. rodgersii in New Zealand, which we compared with populations recently established in Tasmania. The modelled growth rate was only slightly higher in the New Zealand population, and no differences in morphometrics were observed. The New Zealand population structure suggests that annual recruitment occurs regularly, with the population including a range of ages (3 to 10+ years).

Full textAbstract:
Assessment of trophic interactions between increasing populations of New Zealand fur seals (Arctocephalus forsteri) and fisheries in southern Australia is limited due to a lack of species specific demographic data and an understanding of the factors influencing population growth. To establish species specific demographic parameters a cross-sectional sample of New Zealand fur seal females (330) and males (100) were caught and individually-marked on Kangaroo Island, South Australia between 2000 and 2003. The seals were aged through examination of a postcanine tooth, which was removed from each animal to investigate age-specific life-history parameters. Annual formation of cementum layers was confirmed and accuracy in age estimation was determined by examination of teeth removed from individuals of known-age. Indirect methods of assessing reproductive maturity based on mammary teat characteristics indicated that females first gave birth between 4-8 years of age, with an average age at reproductive maturity of 5 years. Among reproductively mature females, age-specific reproductive rates increased rapidly between 4-7 years of age, reaching maximum rates of 70-81% between 8-13 years, and gradually decreased in older females. No females older than 22 years were recorded to pup. Age of first territory tenure in males ranged from 8-10 years. The oldest female and male were 25 and 19 years old, respectively. Post-weaning growth in females was monophasic, characterised by high growth rates in length and mass during the juvenile growth stage, followed by a gradual decline in growth rates after reproductive maturity. In contrast, growth in males was biphasic and displayed a secondary growth spurt in both length and mass, which coincided with sexual and social maturation, followed by a rapid decline in growth rates. Age-specific survival rates were high (0.823-0.953) among prime-age females (8-13 yrs of age) and declined in older females. Relative change in annual pup production was strongly correlated with reproductive rates of prime-age females and adult female survival between breeding seasons.

Full textAbstract:
Hieracium pilosella has become a major concern in the high country grasslands of New Zealand. This thesis provides an understanding of the population dynamics of H. pilosella in an area which has supported the weed as a major component of the vegetation for more than 30 years. The study uses a combined modelling and experimental approach to determine vital rates and regulatory mechanisms. It then uses these to predict the rate of spatial spread, change in density, and the likely impact of biological control. Mature populations of H pilosella at Mt. John were found to be regulated by the
interaction between density-dependent mortality and density-independent reproduction.
The addition of water and/or fertiliser caused an increase in the reproductive vigour of
the plant and a decrease in density while simulated grazing (i.e. mowing) had little effect
on the population. A link was found between reproductive vigour and rosette size or age
(50% of first year rosettes reproduced while only 11 % of older rosettes did), although the
reproductive threshold size (23 mm diameter) appeared to be independent of age.
Rosettes grown on soil which had previously supported H pilosella had lower growth
and reproductive rates and produced fewer stolons of shorter length. However, there was
little support for either the allelopathic or aluminium toxicity hypotheses for these lower
growth rates.
Spatial population models suggested that in the early stages of colonisation, H pilosella
vital rates are such that it has the potential to occupy 100% of available space but as the
population matures, vital rates change and it is unable to occupy all available space,
probably because of intraspecific competition and a limit on plant size. Spread of
patches was predicted to be 0.5 - 0.8 cm/yr by both explicit spatial simulation models and
analytical diffusion models. Both spatial and non-spatial models predicted that the most
effective agent for biological control would be one which caused an increase in mortality
rather than a decrease in fecundity; to reduce a population by more than 50% a control
agent would have to either increase mortality by 10 - 15 % or decrease daughter
production by 80%.

Full textAbstract:
The terrestrial orchid Thelymitra matthewsii Cheeseman, uncommon in New Zealand, was studied to increase knowledge of the species life cycle, morphology and ecology. Results will enhance future conservation management for the species. New information related to the morphology of T. matthewsii was obtained. The species was found to emerge in one of four discrete life stages of distinctive morphology and height range that remained constant for the season, not developing into a more advanced life stage. The leaf of the three pre adult life stages designated a hook, a spiral, and a non flowering stage, did not inflate at the base, but rose smoothly from the tuber. Apparent morphological differences in the column between descriptions of the Australian taxon and the small New Zealand sample examined suggested further study was needed. Comprehensive monthly monitoring was carried out at five study sites in three locations in the Te Paki area of the Far North, from 2002 to 2004. No patterns emerged in plant life stage succession, flowering, and presence or absence at labels reinforcing the concept that variability was a common component of the population census. Seasonal and partial absence was a major component of the populations. An average of 32.8% of plants, over five study sites, were present throughout three seasons, while 66.9% were recorded as absent (not visible) at monitoring. New plants appearing in 2003 and 2004 showed a high percentage of subsequent absence (mean 85.7%). To determine population stability, recruitment and absence were compared. Plant absence exceeded recruitment by 7% (mean plant absence 30.5%; mean recruitment 23.4%). Plants continued to appear during the monitoring period, and labeled plants increased two-fold over commencement numbers. Adults recorded as 28% of labeled plants over three seasons, were out numbered by pre-flowering stages. Only 5% of population numbers exhibited succession from a smaller to a flowering plant. Life stage modeling indicated a life stage was more likely to be followed by the same stage than an expected successive stage. Thelymitra matthewsii was found to be present in four substrates in the Far North. The survey of vegetation found the indigenous species Kunzea ericoides and the exotic Hakea gibbosa dominant for both height, and cover. Litter and bare ground dominated ground cover. Differences in vegetation and ground cover, of sites supporting T. matthewsii and comparison sites that did not, were minor and suggested that another factor, for example a suitable fungal partner, influenced the species presence or absence. The results of the study indicated the present threat classification of Thelymitra matthewsii is inadequate in the light of the species relatively circumscribed, widely separated habitats, the small number of reproducing individuals and vulnerability to habitat modification.

Full textAbstract:
Spatial heterogeneity of the environment, as measured by floral diversity, composition and structure, is known to influence the distribution and diversity of invertebrates. Heterogeneity brought about by anthropogenic disturbance may be a threat to invertebrate diversity. This thesis investigates the impacts of vegetation heterogeneity at a range of scales on the diversity of invertebrate populations in modified high-altitude indigenous grasslands on the Rock and Pillar Range, Central Otago.
Invertebrates were sampled in and on the edges of snow tussock fragments to assess whether species richness increased systematically with fragment area. Invertebrate composition was poorly related to fragment area, plant composition and environmental variables. Taxon richness, abundance and/or diversity for three invertebrate groups increased as fragment area decreased, perhaps reflecting an influx of species from the surrounding matrix. For snow tussock leaf invertebrates in autumn, richness and abundance were at least two times lower in tussocks exposed to the wind than those in the centre of fragments, suggesting selection of habitat may be based on microclimatic characteristics.
Invertebrates were sampled from the bases of tussocks after they were clipped to simulate three levels of vertebrate grazing. Invertebrate community composition differed between sites and sampling dates but was unaffected by clipping treatment. At the higher altitude site invertebrate abundance was 1.45 times greater and Shannon-Wiener diversity (H�) 1.22 times lower than at the lower altitude site. The latter sampling date had higher abundance (2.12 times) and taxon richness (1.14 times) than the earlier date.
Pitfall-trapped invertebrates in cushionfield, herbfield and snow tussock differed in community composition and often by taxon richness, abundance and diversity. Across habitats, plant composition, plant diversity and some environmental variables were correlated with invertebrate variables, but could not be separated from vegetation type.
The invertebrates collected in the course of the study are listed. Four Phyla, eight Classes, 24 orders and over 300 taxa were recorded. Almost all taxa are endemic and many have limited distributions and/or are undescribed. A species list is provided with collection altitude, method and habitat type.
Invertebrate assemblages from sites differing in altitude, vegetation type and level of habitat modification on the Rock and Pillar Range are compared. Sites differed in species composition and rank orders of abundance and richness. At lower elevations, invertebrate richness was at least 25% less, and standardised trap abundance at least 44% less, than that at the highest elevation. Richness and abundance of exotic invertebrates decreased with increasing altitude.
This thesis highlights several points concerning the study of grassland invertebrates and heterogeneity on the Rock and Pillar Range. First, there are differences in invertebrate assemblages at a range of scales. Conserving invertebrate diversity will therefore require altitudinal sequences and different habitat types, including disturbed areas. At high elevations, tussock habitat may be disproportionately important due to its relative rarity. Second, the effects of disturbance on invertebrates were only visible at large spatial scales. Third, there is a paucity of research on New Zealand invertebrates, especially in regard to terrestrial disturbance, which has resulted in a shortfall of biological, distributional, taxonomic and ecological knowledge.

Full textAbstract:
New Zealand�s fourteen deep-water fiords have complex physical and hydrographic features as well as strong environmental gradients, all of which may influence the population structure of organisms that inhabit the fiords. I examined the population structure of the brachiopod Terebratella sanguinea over ecological and evolutionary time scales in relation to physical and hydrographic features of the fiords. To further explore the role of larval dispersal in this system, comparisons between population genetic structure of T. sanguinea and a brachiopod with a contrasting larval dispersal strategy (Liothyrella neozelanica) were made.
Aspects of the life history of the articulate brachiopod Terebratella sanguinea were measured. I measured density and size throughout Doubtful Sound and growth at outer (5 km from outer coast) and inner fiord sites (13.5 km from outer coast). Additionally, reproductive periodicity was measured at a single site within Doubtful Sound. Terebratella sanguinea occurred at significantly lower densities and was significantly smaller at the outer fiord site (p < 0.05), however growth rates between an inner and outer fiord site did not differ significantly. Terebratella sanguinea was found to have separate sexes and synchronous maturation of oocytes with spawning occurring in the austral winter. These results indicated that, on an ecological time scale, the environmental gradient of the fiords influences aspects of T. sanguinea population structure.
In order to determine the influence of the fiord environment on genetic population structure, patterns among T. sanguinea from across Fiordland were assessed using two genetic markers, and these data were compared to hydrodynamic variables. Ten sites (322 individuals) were included in a preliminary allozyme analysis, and 20 sites (358 individuals) were used for the amplified fragment length polymorphism (AFLP) analysis. Patchy genetic differentiation was revealed with both markers, and a break between Long Sound and the other Fiordland sites was detected with AFLP markers. My results suggest hydrodynamic features of this region may isolate organisms that can disperse only during a planktonic larval phase, however this isolation is visible in genetic patterns only at the most extreme values of the hydrodynamic variables.
To better understand how the fiord environment influences population structure of organisms that disperse via planktonic larvae, I compared population genetic structure of two sympatric brachiopod species that differ in planktonic larval duration. Genetic analysis using the AFLP technique revealed population structuring corresponding to the contrasting modes of larval dispersal. AMOVA analysis indicated Liothyrella neozelanica, a brachiopod that broods its larvae, had more limited exchange among sites within a fiord than did T. sanguinea, a brachiopod that does not brood its larvae. In general, the fiord hydrographic conditions may be creating opportunities for local genetic differentiation (for example Long Sound) in organisms capable of longer distance dispersal, but organisms with lower potential for dispersal are more strongly influenced by ontogeny than by hydrography.
Understanding the population structure of some of the marine fauna of Fiordland is an important cornerstone for the developing management plan for the area. Conservation of the underwater resources of this World Heritage Area can be successful if the structure of the system and the mechanisms driving this structure are taken into account.

Full textAbstract:
Adequate vitamin D status plays an important role in bone health and may also protect against Type 1 Diabetes (T1D), multiple sclerosis and certain cancers. Vitamin D is obtained from two sources; diet and through skin synthesis through the action of ultraviolet (UV) light. Dietary intakes of vitamin D are low in New Zealand (NZ) and the majority of our vitamin D comes from UV exposure. The NZ population may be at risk of low vitamin D status because of low dietary intakes, the country�s latitude (35-46 �S), and high proportion of darker skinned Maori and Pacific People. While case reports have described the occurrence of rickets, predominantly in immigrant groups, there are currently no national data on the vitamin D status of the NZ population. Reports of low vitamin D status in countries of similar latitude to NZ justify an examination of New Zealanders� vitamin D status. The best method to assess of vitamin D status is to measure circulating 25-hydroxyvitamin D concentrations.
This thesis comprises three main studies. The first two had the following aims: to measure 25-hydroxyvitamin D concentrations and their determinants in a national sample (n=1585) of NZ children aged 5-14 y and to measure serum 25-hydroxyvitamin D concentrations and their determinants in a national sample (n=2948) of New Zealanders aged 15 y and over. The 2002 Children�s Nutrition Survey CNS02 was a year long (December, March-November) cross-sectional survey of a nationally representative sample of NZ school children 5-14 y. Over-sampling of Maori and Pacific children allowed ethnic specific analyses. The 1997 National Nutrition Survey (NNS97) participants were recruited over one year according to an area-based sampling frame with a 3 stage stratified design consisting of primary sampling units, households within each unit, and one randomly selected respondent from each household. Mean (99% CI) serum 25-hydroxyvitamin D concentrations were similar in children and adults (both 50 nmol/L). Among Maori, Pacific and NZEO children respectively, prevalence (%, 99% CI) of serum 25-hydroxyvitamin D deficiency (< 17.5 nmol/L) was 5% (2, 12), 8% (5, 14), and 3% (1,7). Based on a cutoff of < 37.5 nmol/L, prevalence of insufficiency was 41% (29, 53), 59% (42, 75) and 25% (15, 35), respectively. Based on a cutoff of 50 nmol/L, 56% of children were insufficient. Three percent of adult New Zealanders had serum 25-hydroxyvitamin D concentrations indicative of deficiency ([less than or equal to] 17.5 nmol/L); 48% and 84% were insufficient based on cutoffs of [less than or equal to] 50 and [less than or equal to] 80 nmol/L The main determinants of vitamin D status in NZ children were season, ethnicity and sex. After adjustment for other factors and covariates, boys had an adjusted mean (99% CI) 25-hydroxyvitamin D concentration 5 (1, 9) nmol/L higher than girls, Maori children were 7 (2, 11) and Pacific children 15 (11, 20) nmol/L lower than NZ European and Other (NZEO) children. Obese children were 7 (2, 11) nmol/L lower than overweight or �normal� weight. Children�s mean 25-hydroxyvitamin D concentrations (adjusted for other variables) peaked in March (69 nmol/L) and was at its lowest in August (36 nmol/L).
In adults, there were effects of a similar magnitude of ethnicity and season on serum 25-hydroxyvitamin D concentrations. Obesity, latitude and age were determinants of vitamin D status in women but not men. Obese (BMI > 30) women had an adjusted mean vitamin concentration 6 (3, 10) nmol/L lower than women with BMI < 25. Women living in the South Island were 6 (3, 9) nmol/L lower than women living in the North Island. Additionally, adjusted mean serum 25-hydroxyvitamin D was 13 (8, 18) higher in women 15 -18 y than women 65 y or older.
The third and final study aimed to determine whether the higher rates of vitamin D inadequacy reported in the winter than summer months in NZ also result in higher PTH concentrations, which would provide evidence for functional effect of inadequate vitamin D status. We also aimed to objectively explore the effect of natural skin colour on vitamin D status, given the higher prevalence of vitamin D insufficiency in dark-skinned groups living far from the equator. Skin colour measurements were taken with a hand-held light reflectometer (Datacolor Mercury[TM] 1000 colorimeter, Lawrenceville, NJ).
In the 342 residents of Invercargill and Dunedin, mean serum 25-hydroxyvitamin D concentrations were lower in the late summer versus early spring (79 vs 51 nmol/L; P< 0.001). The lower serum 25-hydroxyvitamin D in early spring versus summer was associatedwith a 2 pg/mL (P< 0.001) higher parathyroid hormone (PTH) concentration. Interestingly, no significant effect of natural skin colour, based on light reflectance at the inside of the upper arm, was discovered, though there was a positive effect of tanning, based on light reflectance at the upper forearm, on serum 25-hydroxyvitamin D concentrations.
Ethnicity and season are major determinants of serum 25-hydroxyvitamin D in New Zealanders. There is a high prevalence of vitamin D insufficiency in NZ children and adults, which may contribute to increased risk of osteoporosis and other chronic disease. While there is a pressing need for more convincing evidence with regards to the health risks associated with the low vitamin D status in children, evidence from the study of adults, where higher PTH concentrations were found during spring versus summer, suggests that the low 25-hydroxyvitamin D concentrations are having an adverse effect on bone health of adults. The high prevalence of vitamin D insufficiency in New Zealanders, warrants serious consideration of strategies such as fortification, to improve the vitamin D status of the population.

Full textAbstract:
Nototodarus sloanii is an important component of the Southern Ocean fauna, and the basis of a large commercial fishery. Despite this, much is unknown about the biology of this species. This study examines some aspects of the biology of N. sloanii.
Stomach contents analysis identified no significant differences in diet between male and female squid. Sixteen putative species, including 12 identifiable teleosts, 2 crustaceans, and 2 cephalopods were identified in the diet of this species. The euphausid, Nyctiphanes australis was the most important prey item, Lanternfish, Lampanyctodes hectoris, and Pearlside, Maurolicus muelleri, were of secondary importance.
Squid were aged using counts of statolith micro-increments and back-calculation from the date of capture showed that hatching occurred between August and February, with a peak in the austral winter/spring and another smaller peak in the austral summer. Growth rate for male squid differed depending on whether squid were hatched in the winter/spring or summer. Growth rates were more variable in the winter/spring-hatched individuals, and they attained larger size than summer-hatched squid. This was not the case for female squid. Mean age for immature winter/spring-hatched squid was significantly higher than for summer-hatched squid, although there was no significant difference in mean mantle length or body mass. No significant differences between mean age, mantle length, or body mass for same-gender mature squid, regardless of hatch season, were apparent. However, mature female squid hatched in the winter/spring season were significantly longer (ML) than mature male squid hatched in winter/spring. No squid was found to be older than 211 days. All squid had started to mature by 91-120 days old and all were fully mature at 180 days.
Validation experiments run on juvenile squid using calcein markers were inconclusive, however the increments in the statoliths were very similar to those found in other validated species of ommastrephid squid, thus for the purposes of this study they were assumed to be of daily periodicity.
Gladius increments identify a gender difference in growth rate, with female squid having a shorter initial slow growth phase than male squid.
Gonadosomatic indices (GSIs) were calculated for male and female squid. These were low (7.12%�0.3% for females and 1.9%�0.2% for males) suggesting that these squid are intermittent spawners. This is further supported by a histological examination, which found germinal cells of different stages present in the same gonad. Lack of mature individuals in this study means that these results are suggestive rather than definitive; more examination of the reproductive process of this squid is required. Histological examination was also used to validate the Lipinski maturity scale for use with this species, while some misidentification occurred the scale is useful to place squid into the broad categories of immature, maturing, or mature. New maturity scales were created for N. sloanii utilising these broad categories. Finer-scale identification is not possible using this scale, as maturation appears to be a continuous process.
Morphometric measurements were taken from both hard and soft tissues and were analysed using non-metric multidimensional scaling and analysis of similarity. Divisions were only apparent in the hard structure measurements. They did not appear to be age, dietary or reproductive differences.

Full textAbstract:
The aim of this study was to investigate population densities and dynamics of brown trout along multiple tributaries of the Taieri River, a large New Zealand river. Relationships between juvenile brown trout population dynamics and food availability, discharge and water temperature were examined in the same lowland stream. Downstream movements of juvenile brown trout were also examined. Trace element analyses of eggs aimed to identify the source of fish spawning in tributary streams. An experimental study of juvenile brown trout collected from downstream and upstream reaches compared patterns of agonistic behaviour amongst trout that were considered to be dominated by either migratory (downstream) or resident (upstream) fish. Longitudinal surveys of juvenile trout abundance were expanded across four additional streams to determine whether there were consistent patterns in population dynamics of brown trout.
Large spatial and temporal variation in population dynamics of juvenile brown trout was found in Silverstream with an upstream site having significantly less temporal variation in densities than a downstream site. No effect of food availability on population dynamics was found. Discharge and temperature affected population densities of juvenile brown trout in some years, but could not solely explain the general pattern in spatial variation in population dynamics. Downstream movement was found to be a behavioural strategy used by juvenile brown trout and appeared to contribute to variation in juvenile density.
Analysis of trace element signatures in brown trout eggs indicated that upstream spawning migration by anadromous females was restricted by the presence of a steep gorge along the middle reaches of the Taieri River. Patterns of spawning by migratory and resident fish along tributary streams appeared to vary. In Silverstream, spawning by anadromous fish dominated the lower reaches, whereas considerable overlap between anadromous and resident fish was observed in Big Stream. In Cap Burn distinct trace element signatures were observed for redds spawned along upstream and downstream reaches. However, it was not possible to confidently ascribe the source of the redds to main river migrants or Cap Burn resident fish.
Behavioural observations of juvenile brown trout collected from upstream (resident) and downstream (migratory) reaches of Silverstream revealed differences in aggression level, with migratory fish being more aggressive. No difference in growth rates was found between fish from the two areas. Furthermore, the social organisation of resident fish was based on the formation of dominance hierarchies, whereas the competitive status of migratory fish was more even.
Patterns in spatial and temporal variation in the longitudinal population dynamics and patterns of abundance of juvenile trout were repeated across the five tributaries. Populations in upstream reaches consisted of fish from multiple age classes and exhibited relatively limited variation in densities, whereas juvenile fish dominated populations along downstream reaches and densities varied greatly over an annual cycle.
Taken together, these results suggest a general pattern of spatial and temporal variation in the population dynamics of brown trout sub-populations along tributaries of a large New Zealand river. Whilst various environmental factors may contribute to some of the variation, longitudinal separation into resident and migratory populations also appeared to be important. These finding are important for the management of brown trout in both main river channels and tributaries in New Zealand.

Full textAbstract:
This thesis is about the demography of the tunicate Styela clava, a species of some notoriety because of its invasiveness and impacts in many parts of the world. Species assemblages have continuously changed throughout evolutionary history, but the rate of today’s anthropogenically facilitated dispersal is unparalleled in history. Non-indigenous species (NIS) are now considered one of the most important risks to native biodiversity. NIS become invasive by becoming both widespread and locally dominant. This requires that a species becomes established, spreads locally, and increases in abundance. In the early stages of invasion, its demography and life history characteristics are of crucial importance. In New Zealand, Styela has established populations in several places, but none of these populations has yet reached the high densities found in other countries. In Lyttelton Port, where this study was located, Styela was first noticed in 2005. It therefore presented an ideal situation to study an invasive species in its early stages of establishment and provided a potentially good model for understanding how invasive species get local traction and spread from initial infestation points. Therefore, I set out to determine demographic features of Styela to understand the numbers game of population dynamics.
This study used empirical data on growth rates, size-frequencies through time, and size and age to maturity to test several models, including von Bertalanffy, Logistic dose-response, Ricker and power models of individual growth. The most useful proved to be the von Bertalanffy model. Styela individuals shrink frequently, so average growth rates were often quite low, even though some individuals reached 160 mm or more in total length. Mortality was greatest in summer, presumably after reproduction, and lowest in winter. Fewer than 5% of individuals survived 12 months, and most or all of these died soon afterwards. Populations were, therefore, essentially annual. Recruitment was difficult to determine because of the cryptic nature of small juveniles. However, size-frequency, abundance and mortality data indicated that recruitment most likely occurred in early spring (late-October), and then again in late summer, with growth to maturity (at c. 50 mm total length) within < 5 months.
Several manipulative experiments showed that Styela did not readily capitalise on provision of free space but the other non-native ascidian, Ciona intestinalis, rapidly recruited. Transplants of Styela were greatly affected by C. intestinalis, which overgrew them, similar to a localised replacement of Styela by Ciona seen overseas.
Lefkovitch modelling was used to test whether Styela had an “Achilles heel” in its life history, whereby managed removal could impact future populations. This showed that under several scenarios intervention would most likely be ineffectual.
Overall, this study showed that the original populations in Lyttelton Port are either static or in decline, somewhat contrary to original expectations. Nevertheless, it appears that these small populations may be acting as stepping stones for spread of this species outside of the port.

Full textAbstract:
The sooty shearwater (also known as the muttonbird, Titi, Puffinus griseus) is a long-lived super-abundant, burrow nesting petrel, harvested by Rakiura Maori from breeding colonies, located in southern New Zealand. The harvest is culturally defining and enormously important for Rakiura Maori. The work in this thesis contributes to the Kia Mau te Titi Mo Ake Tonu Atu Research Project being undertaken by Rakiura Maori and the University of Otago, towards assessing ongoing sustainability of the harvest and future threats.
Analyses of eight muttonbirder harvest records spanning, 1938 to 2004, show that harvest rates demonstrate, systematic commonalities in seasonal patterns and broad-scale consistency in trends of chick abundance and quality across harvested islands. If co-ordinated and well replicated, harvest records offer Rakiura Maori a low-cost and effective monitoring tool of sooty shearwater reproductive success and long-term population abundance. Hunt tallies provide additional evidence of a dramatic reduction in sooty shearwater abundance from the late 1980s that was also detected by counts from boats off the western seaboard of the USA. A conservative estimate of overall decline in hunt success across diaries, for the period 1972 to 2004, is 1.89 % (CI₉₅ 1.14 to 2.65) per annum, a total reduction of 39.2%. The harvesting records show a sooty shearwater mortality event occurred just prior to the 1993-breeding season at the same time as a severe negative anomaly in both the Pacific Decadal Oscillation and Southern Oscillation Indices. The hunting diaries show a decoupling of chick size with harvest success in the early 1990s. This resulted from a decline in harvest success and an increase in its variability, while chick size remained correlated with changing chick abundance and maintained its pre-1990 average. Long- lived seabirds maintain high survival by skipping breeding and abandoning breeding attempts when oceanic conditions deteriorate, increasing variability in chick abundance is also evidence of pressure on adult survivorship. The multiple diaries confirm these were major demographic events not confined to a single island.
My survival estimates for The Snares and Whenua Hou were very high 0.952 (0.896-0.979) compared to earlier estimates for this species. Transience at the colonies is high due to the presence ofjuvenile and pre-breeding birds. Both naturally high survival and the large number of transient pre-breeders indicate sooty shearwater are more resilient to harvest than earlier survival models suggested. There was no evidence for directional change in sooty shearwater breeding phenology over 49-years of harvest. Climate fluctuation/change is therefore apparently not altering egg-laying. Peak fledging occurred fairly consistently in the 2nd of May (IQR = 2.91 days). Yearly variability in emergence occurs primarily due to provisioning and localized fledging conditions. Larger chick size was strongly correlated with delayed fledging and is consistent with the traditional ecological knowledge of the birders. There was no evidence for chicks becoming smaller or that years with starving chicks were more common, so increasing mismatch of breeding with optimal forage was not indicated.
The past proportion of birders over the last 20 years (1985 - 2005) has been ~2% all of Rakiura Maori. Approximately 376 birders participated in the 2006 season with an estimated of overall harvest intensity 19.4% (CI₉₅ = 13.8 - 24.2%) and a total catch of 381,000 (CI₉₅ = 262,257 - 487,186) chicks. This study found evidence that catch rates reduced with increasing birder competition partially mitigating effects on harvest pressure. The combined effects of potential climate change on bird abundance and increased harvester competition suggests that the proportion of Rakiura Maori whom choose to bird is likely to decrease as tallies reduce and cost recovery becomes more difficult. Rakiura Maori have for many years cherished and maintained their islands and implemented protective measures to safeguarded titi breeding habitat. Future harvest management will have additional issues to contend with, but Rakiura Maori are necessarily confronting these issues as the titi culture rests on the maintenance of their taonga. The information presented in this thesis shows that combining science and traditional knowledge is a powerful tool for managing harvest sustainability.

Full textAbstract:
This paper takes up one of the conference themes, «Reflection of language contacts in proper names». It deals with the situation in New Zealand where there are some 12,000 gazetted (or official) and an estimated 35,000 nongazetted (or recorded) place names. These names are almost all in Māori and English. The country was settled by the Māori people in the fourteenth century and today about 650,000 people, out of a total population of about 4.3 million, claim Māori descent. Māori named almost all of the country, the names being closely linked to iwi (tribal) histories. Foreigners, almost all English speaking, started visiting the country and giving their names to various places, and from the early nineteenth century two place name systems – Māori and nonMāori – have existed. This paper details the contact between the Māori language, the English language and New Zealand’s place names. It deals with seven matters: (1) Māori settlement and naming; (2) Early nonMāori settlement and naming; (3) the Treaty of Waitangi; (4) post Treaty of Waitangi names; (5) spelling of Māori place names; (6) prounciation of Māori names; and (7) dual and alternative Māori-English place names. Reasons are advanced to explain matters associated with the interlingual problems in the spelling and pronunciation of the place names and the emergence of dual place names.

Full textAbstract:
"E-health has transformed healthcare by improving access and reach of health services, which is now more critical than ever given the COVID-19 pandemic. One aspect of e-health is the delivery of health interventions via the internet or through smartphone apps, known as digital interventions (DI). These DI can improve physical and mental health for people, by modifying behaviour and improving illness management. Despite, the benefits of DI use remains low. One explanation for this low usage is people’s attitudes towards DI. Indeed, having a positive attitude towards DI is associated with an increased likelihood of wanting to engage with DI. Therefore, people’s attitudes towards digital interventions are important in understanding if people are willing to engage with them. To date, limited research exists about attitudes and much of this varies based on region and population. Along, with understanding people’s attitudes it is important to understand what shapes people’s attitudes towards these interventions. Therefore, this study sought to determine New Zealand (NZ) adults’ attitudes towards DI and what shapes these attitudes. In order to address these questions a cross-sectional survey was used. Results indicate that NZ adults have neutral to somewhat positive attitudes to DI and their attitudes are influenced by common factors including: beliefs about accessibility of DI and the COVID-19 experience. These findings suggest that some NZ adults have a positive attitudes to DI, but overall people’s attitudes needed to be addressed to ensure people are ready to use DI."

Full textAbstract:
This paper is based on archival research done for a larger project looking at the impact of emergent transnational networks in Asia on the work of New South Wales architects. During the period of the Cultural Revolution in China (1966-1976), the neighbouring territories of Macau and Hong Kong served as centres of resistance, where an expatriate population interested in traditional Asian arts and culture would find growing support and patronage amongst the elite intellectual class. This brought influential international actors in the fields of journalism, filmmaking, art and architecture to the region, including a number of Australian architects. This paper traces the history of one such Australian émigré, Alan Gilbert, who arrived in Macau in 1963 just before the Cultural Revolution and continued to work as a professional filmmaker and photojournalist documenting the revolution. In 1967 he joined the influential design practice of Dale and Patricia Keller (DKA) in Hong Kong, where he met his future wife Sarah Lo. By the mid 1970s both Alan Gilbert and Sarah Lo had left to start their own design practice under Alan Gilbert and Associates (AGA) and Innerspace Design. The paper particularly explores their engagement with ‘reform-era’ China in the late 1970s and early 1980s when they secured one of the first and largest commissions awarded to a foreign design firm by the Chinese government to redesign a series of nine state- run hotels, two of which, the Minzu and Xiyuan Hotels in Beijing, are discussed here.

Full textAbstract:
In the 1970s, rapid modernisation fuelled population displacement and increased the number of workers in the large cities of Iran, in particular Tehran. In response, the Imperial Government initiated several housing programs focusing on the provision of megastructures on a large scale. Consequently, a new opposition formed among some sectors of society, regarding the dissemination of gigantic buildings in the International or Brutalist styles. Critics and clerics argued that the radical government interventions not only polarised the image of Islamic identity in cities, but also affected the behaviour of people towards, and their opinions concerning, the Islamic lifestyle. Additionally, some claimed the state aimed to normalise its project of modernity and rapid westernisation for the mid- and lower classes using housing. In this regard, this article investigates the 1970s imperial government social housing programs to verify these claims. Using an extensive literature review, documentary research, observation, and descriptive data analysis, this article argues that, despite the government politics and modernisation tendencies in the 1970s, consumerism, political competition, the state of Cold War, and the emergence of new construction techniques, all resulted in the emergence of mass-produced megastructures offering a new luxurious lifestyle to residents. While the life and hygiene of the different classes were improved, these instant products inevitably facilitated the normalisation of Western lifestyle among the mid- and low-income groups of the society. Eventually, this visible social transition was utilised by opposition leaders as another excuse to topple the Pahlavi regime under the 1979 Islamic Revolution.

Full textAbstract:
This paper presents projections for 18 Latin America and Caribbean countries of pensions and health expenditures over the next 50 years, compares them to advanced countries, and calculates estimates of the fiscal gap due to aging. The exercise is crucial since life expectancy is increasing and fertility rates are declining in virtually all advanced countries and many developing countries, but more so in Latin America and the Caribbean. While the populations of many of the regions countries are still relatively young, they are aging more rapidly than those in more developed countries. The fiscal implications of these demographic trends are severe. The paper proposes policy and institutional reforms that could begin to be implemented immediately and that could help moderate these trends in light of relevant international experience to date. It suggests that LAC countries need to include an intertemporal numerical fiscal limit or rule to the continuous increase in aging spending while covering the needs of the more vulnerable. They should consider also complementing public pensions with voluntary contribution mechanisms supported by tax incentives, such as those used in Australia, New Zealand (Kiwi Saver), and the United States (401k). In addition, LAC countries face an urgent challenge in curbing the growth of health care costs, while improving the quality of care. Efforts should focus on improving both the allocative and the technical efficiency of public health spending.

The International Health Regulations (2005) are legally binding on 196 States Parties, Including all WHO Member States. The IHR aims to keep the world informed about public health risks, through committing all signatories to cooperate together in combating any future “illness or medical condition, irrespective of origin or source, that presents or could present significant harm to humans.” Under IHR, countries agreed to strengthen their public health capacities and notify the WHO of any such illness in their populations. The WHO would be the centralized body for all countries facing a health threat, with the power to declare a “public health emergency of international concern,” issue recommendations, and work with countries to tackle a crisis. Although, with the sudden and rapid spread of COVID-19 in the world, many countries varied in implementing the WHO guidelines and health recommendations. While some countries followed the WHO guidelines, others imposed travel restrictions against the WHO’s recommendations. Some refused to share their data with the organization. Others banned the export of medical equipment, even in the face of global shortages. The UN Compliance Research group will focus during the current cycle on analyzing the compliance of the WHO member states to the organizations guidelines during the COVID-19 pandemic.

Full textAbstract:
Background Lung cancer is the number one cause of cancer death worldwide.(1) It is the fifth most commonly diagnosed cancer in Australia (12,741 cases diagnosed in 2018) and the leading cause of cancer death.(2) The number of years of potential life lost to lung cancer in Australia is estimated to be 58,450, similar to that of colorectal and breast cancer combined.(3) While tobacco control strategies are most effective for disease prevention in the general population, early detection via low dose computed tomography (LDCT) screening in high-risk populations is a viable option for detecting asymptomatic disease in current (13%) and former (24%) Australian smokers.(4) The purpose of this Evidence Check review is to identify and analyse existing and emerging evidence for LDCT lung cancer screening in high-risk individuals to guide future program and policy planning. Evidence Check questions This review aimed to address the following questions: 1. What is the evidence for the effectiveness of lung cancer screening for higher-risk individuals? 2. What is the evidence of potential harms from lung cancer screening for higher-risk individuals? 3. What are the main components of recent major lung cancer screening programs or trials? 4. What is the cost-effectiveness of lung cancer screening programs (include studies of cost–utility)? Summary of methods The authors searched the peer-reviewed literature across three databases (MEDLINE, PsycINFO and Embase) for existing systematic reviews and original studies published between 1 January 2009 and 8 August 2019. Fifteen systematic reviews (of which 8 were contemporary) and 64 original publications met the inclusion criteria set across the four questions. Key findings Question 1: What is the evidence for the effectiveness of lung cancer screening for higher-risk individuals? There is sufficient evidence from systematic reviews and meta-analyses of combined (pooled) data from screening trials (of high-risk individuals) to indicate that LDCT examination is clinically effective in reducing lung cancer mortality. In 2011, the landmark National Lung Cancer Screening Trial (NLST, a large-scale randomised controlled trial [RCT] conducted in the US) reported a 20% (95% CI 6.8% – 26.7%; P=0.004) relative reduction in mortality among long-term heavy smokers over three rounds of annual screening. High-risk eligibility criteria was defined as people aged 55–74 years with a smoking history of ≥30 pack-years (years in which a smoker has consumed 20-plus cigarettes each day) and, for former smokers, ≥30 pack-years and have quit within the past 15 years.(5) All-cause mortality was reduced by 6.7% (95% CI, 1.2% – 13.6%; P=0.02). Initial data from the second landmark RCT, the NEderlands-Leuvens Longkanker Screenings ONderzoek (known as the NELSON trial), have found an even greater reduction of 26% (95% CI, 9% – 41%) in lung cancer mortality, with full trial results yet to be published.(6, 7) Pooled analyses, including several smaller-scale European LDCT screening trials insufficiently powered in their own right, collectively demonstrate a statistically significant reduction in lung cancer mortality (RR 0.82, 95% CI 0.73–0.91).(8) Despite the reduction in all-cause mortality found in the NLST, pooled analyses of seven trials found no statistically significant difference in all-cause mortality (RR 0.95, 95% CI 0.90–1.00).(8) However, cancer-specific mortality is currently the most relevant outcome in cancer screening trials. These seven trials demonstrated a significantly greater proportion of early stage cancers in LDCT groups compared with controls (RR 2.08, 95% CI 1.43–3.03). Thus, when considering results across mortality outcomes and early stage cancers diagnosed, LDCT screening is considered to be clinically effective. Question 2: What is the evidence of potential harms from lung cancer screening for higher-risk individuals? The harms of LDCT lung cancer screening include false positive tests and the consequences of unnecessary invasive follow-up procedures for conditions that are eventually diagnosed as benign. While LDCT screening leads to an increased frequency of invasive procedures, it does not result in greater mortality soon after an invasive procedure (in trial settings when compared with the control arm).(8) Overdiagnosis, exposure to radiation, psychological distress and an impact on quality of life are other known harms. Systematic review evidence indicates the benefits of LDCT screening are likely to outweigh the harms. The potential harms are likely to be reduced as refinements are made to LDCT screening protocols through: i) the application of risk predication models (e.g. the PLCOm2012), which enable a more accurate selection of the high-risk population through the use of specific criteria (beyond age and smoking history); ii) the use of nodule management algorithms (e.g. Lung-RADS, PanCan), which assist in the diagnostic evaluation of screen-detected nodules and cancers (e.g. more precise volumetric assessment of nodules); and, iii) more judicious selection of patients for invasive procedures. Recent evidence suggests a positive LDCT result may transiently increase psychological distress but does not have long-term adverse effects on psychological distress or health-related quality of life (HRQoL). With regards to smoking cessation, there is no evidence to suggest screening participation invokes a false sense of assurance in smokers, nor a reduction in motivation to quit. The NELSON and Danish trials found no difference in smoking cessation rates between LDCT screening and control groups. Higher net cessation rates, compared with general population, suggest those who participate in screening trials may already be motivated to quit. Question 3: What are the main components of recent major lung cancer screening programs or trials? There are no systematic reviews that capture the main components of recent major lung cancer screening trials and programs. We extracted evidence from original studies and clinical guidance documents and organised this into key groups to form a concise set of components for potential implementation of a national lung cancer screening program in Australia: 1. Identifying the high-risk population: recruitment, eligibility, selection and referral 2. Educating the public, people at high risk and healthcare providers; this includes creating awareness of lung cancer, the benefits and harms of LDCT screening, and shared decision-making 3. Components necessary for health services to deliver a screening program: a. Planning phase: e.g. human resources to coordinate the program, electronic data systems that integrate medical records information and link to an established national registry b. Implementation phase: e.g. human and technological resources required to conduct LDCT examinations, interpretation of reports and communication of results to participants c. Monitoring and evaluation phase: e.g. monitoring outcomes across patients, radiological reporting, compliance with established standards and a quality assurance program 4. Data reporting and research, e.g. audit and feedback to multidisciplinary teams, reporting outcomes to enhance international research into LDCT screening 5. Incorporation of smoking cessation interventions, e.g. specific programs designed for LDCT screening or referral to existing community or hospital-based services that deliver cessation interventions. Most original studies are single-institution evaluations that contain descriptive data about the processes required to establish and implement a high-risk population-based screening program. Across all studies there is a consistent message as to the challenges and complexities of establishing LDCT screening programs to attract people at high risk who will receive the greatest benefits from participation. With regards to smoking cessation, evidence from one systematic review indicates the optimal strategy for incorporating smoking cessation interventions into a LDCT screening program is unclear. There is widespread agreement that LDCT screening attendance presents a ‘teachable moment’ for cessation advice, especially among those people who receive a positive scan result. Smoking cessation is an area of significant research investment; for instance, eight US-based clinical trials are now underway that aim to address how best to design and deliver cessation programs within large-scale LDCT screening programs.(9) Question 4: What is the cost-effectiveness of lung cancer screening programs (include studies of cost–utility)? Assessing the value or cost-effectiveness of LDCT screening involves a complex interplay of factors including data on effectiveness and costs, and institutional context. A key input is data about the effectiveness of potential and current screening programs with respect to case detection, and the likely outcomes of treating those cases sooner (in the presence of LDCT screening) as opposed to later (in the absence of LDCT screening). Evidence about the cost-effectiveness of LDCT screening programs has been summarised in two systematic reviews. We identified a further 13 studies—five modelling studies, one discrete choice experiment and seven articles—that used a variety of methods to assess cost-effectiveness. Three modelling studies indicated LDCT screening was cost-effective in the settings of the US and Europe. Two studies—one from Australia and one from New Zealand—reported LDCT screening would not be cost-effective using NLST-like protocols. We anticipate that, following the full publication of the NELSON trial, cost-effectiveness studies will likely be updated with new data that reduce uncertainty about factors that influence modelling outcomes, including the findings of indeterminate nodules. Gaps in the evidence There is a large and accessible body of evidence as to the effectiveness (Q1) and harms (Q2) of LDCT screening for lung cancer. Nevertheless, there are significant gaps in the evidence about the program components that are required to implement an effective LDCT screening program (Q3). Questions about LDCT screening acceptability and feasibility were not explicitly included in the scope. However, as the evidence is based primarily on US programs and UK pilot studies, the relevance to the local setting requires careful consideration. The Queensland Lung Cancer Screening Study provides feasibility data about clinical aspects of LDCT screening but little about program design. The International Lung Screening Trial is still in the recruitment phase and findings are not yet available for inclusion in this Evidence Check. The Australian Population Based Screening Framework was developed to “inform decision-makers on the key issues to be considered when assessing potential screening programs in Australia”.(10) As the Framework is specific to population-based, rather than high-risk, screening programs, there is a lack of clarity about transferability of criteria. However, the Framework criteria do stipulate that a screening program must be acceptable to “important subgroups such as target participants who are from culturally and linguistically diverse backgrounds, Aboriginal and Torres Strait Islander people, people from disadvantaged groups and people with a disability”.(10) An extensive search of the literature highlighted that there is very little information about the acceptability of LDCT screening to these population groups in Australia. Yet they are part of the high-risk population.(10) There are also considerable gaps in the evidence about the cost-effectiveness of LDCT screening in different settings, including Australia. The evidence base in this area is rapidly evolving and is likely to include new data from the NELSON trial and incorporate data about the costs of targeted- and immuno-therapies as these treatments become more widely available in Australia.

Full textAbstract:
The goal of the one-year feasibility study was to identify specific cytotoxic T-lymphocyte (CTL) epitopes to Neosporacaninum in the natural bovine host in order to make progress toward developing an effective peptide-based vaccine against bovine neosporosis. We tested the hypothesis that: N. caninum SRS2 peptides contain immunogenicCTLepitope clusters cross-presented by multiple bovine MHC-I and MHC-IIhaplotypes. The specific objectives were: (1) Map bovine CTLepitopes of N. caninum NcSRS-2 and identify consensus MHC-I and class-II binding motifs; and (2) Determine if subunit immunization with peptides containing N. caninum-specificCTLepitopes cross-reactive to multiple bovine MHChaplotypes induces a CTL response in cattle with disparate MHChaplotypes. Neosporosis is a major cause of infectious abortion and congenital disease in cattle, persisting in cattle herds via vertical transmission.5 N. caninum abortions are reported in Israel; a serological survey of 52 Israeli dairy herds with reported abortions indicated a 31% infection rate in cows and 16% infection rate in aborted fetuses.9,14 Broad economic loss due to bovine neosporosis is estimated at $35,000,000 per year in California, USA, and $100,000,000 (Australian) per year in Australia and New Zealand.13 Per herd losses in a Canadian herd of 50 cattle are estimated more conservatively at $2,305 (Canadian) annually.4 Up to date practical measures to reduce losses from neosporosis in cattle have not been achieved. There is no chemotherapy available and, although progress has been made toward understanding immunity to Neospora infections, no efficacious vaccine is available to limit outbreaks or prevent abortions. Vaccine development to prevent N. caninum abortion and congenital infection remains a high research priority. To this end, our research group has over the past decade: 1) Identified the importance of T-lymphocyte-mediated immunity, particularly IFN-γ responses, as necessary for immune protection to congenital neosporosis in mice,1,2,10,11 and 2) Identified MHC class II restricted CD4+ CTL in Neosporainfected Holstein cattle,16 and 3) Identified NcSRS2 as a highly conserved surface protein associated with immunity to Neospora infections in mice and cattle.7,8,15 In this BARD-funded 12 month feasibility study, we continued our study of Neospora immunity in cattle and successfully completed T-lymphocyte epitope mapping of NcSRS2 surface protein with peptides and bovine immune cells,15 fulfilling objective 1. We also documented the importance of immune responses NcSRS2 by showing that immunization with native NcSRS2 reduces congenital Neospora transmission in mice,7 and that antibodies to NcSRS2 specifically inhibition invasion of placental trophoblasts.8 Most importantly we showed that T-lymphocyte responses similar to parasite infection, namely induction of activated IFN-γ secreting Tlymphocytes, could be induced by subunit immunization with NcSRS2 peptides containing the Neospora-specificCTLepitopes (Baszler et al, In preparation) fulfilling objective 2. Both DNA and peptide-based subunit approaches were tested. Only lipopeptide-based NcSRS2 subunits, modified with N-terminal linked palmitic acid to enhance Toll-like receptors 2 and 1 (TLR2-TLR1), stimulated robust antigen-specific T-lymphocyte proliferation, IFN-γ secretion, and serum antibody production across different MHC-IIhaplotypes. The discovery of MHC-II cross-reactive T-cellinducing parasite peptides capable of inducing a potentially protective immune response following subunit immunization in cattle is of significant practical importance to vaccine development to bovine neosporosis. In addition, our findings are more widely applicable in future investigations of protective T-cell, subunit-based immunity against other infectious diseases in outbred cattle populations.
