Abstract:

Cane toads from an urban population in Townsville, Qld, exhibit poor body condition and small body size, as do toads in populations around Townsville which have declined in numbers. The small body size and poor condition are associated with a high food intake and a low rate of parasitism. The results suggest that decline of rural populations is not a product of parasitism, or food and or water shortages related to unusually adverse seasonal conditions. Populations of cane toads around Townsville declined more than 3 years before this study.

Abstract:

Abstract The passage of three Australian Category 5 cyclones within 350 km of Darwin (Northern Territory), Australia, during the last decade indicates that that city should have a high wind hazard. In this paper, the wind hazard for Darwin was compared with that for Port Hedland (Western Australia) and Townsville (Queensland) using data from a coupled ocean–atmosphere simulation model and from historical and satellite-era records of tropical cyclones. According to the authoritative statement on wind hazard in Australia, Darwin’s wind hazard is the same as Townsville’s but both locations’ hazards are much less than that of Port Hedland. However, three different estimates in this study indicate that Darwin’s wind hazard at the long return periods relevant to engineering requirements is higher than for both Port Hedland and Townsville. The discrepancy with previous studies may result from the inadequate cyclone records in the low-latitude north of Australia, from accumulated errors from estimates of wind speeds from wind fields and wind–pressure relationships, and from inappropriate extrapolations of short-period records based on assumed probability distributions. It is concluded that the current wind-hazard zoning of northern Australia seriously underestimates the hazard near Darwin and that coupled ocean–atmosphere simulation models could contribute to its revision.

Abstract:

Abstract: Seed of Townsville stylo (Stylosanthes humilis H.B.K.) is known to exhibit a hard seed coat and when freshly harvested also show a physiological dormancy, however, the nature of the co-actions between seed coat and embryo growth that determine dormancy is poorly understood. In this study, physical dormancy of Townsville stylo seeds was not reduced during natural ageing at room temperature, in contrast to the physiological dormancy, which is gradually overcome during after-ripening. Furthermore, the permeability of seed coat was affected by scarification treatments as well as by low-pH solutions. Together, these data indicate that physical dormancy overcome of seed is prerequisite for radicle protrusion and physiological dormancy of Townsville stylo seeds contribute to its timing.

Abstract:

SUMMARYThe aims of this study were to define the basic epidemiology of serologically confirmed acute Q fever in patients tested via the Townsville Hospital laboratory from 2000 to 2010 and to determine the impact of geographical location and seasonality on the incidence of acute cases in the Townsville region. Seven Statistical Local Areas (SLA) were identified as having an incidence higher than the average Queensland incidence over the study period. The SLA with the highest incidence was Woodstock-Ross with 24·9 cases/100 000. A clear seasonal peak was found, with the greatest number of cases observed in May, 3 months following the peak in rainfall in February. We hypothesize that an increase in wildlife numbers and drier conditions seen immediately following the wet season is the reason for the seasonal peak of human acute Q fever cases in Townsville.

Abstract:

Dendrobium speciosum Sm. has received insufficient taxonomic study north of St Lawrence, Queensland, where plants display much morphological variation in diverse habitats. Two varieties have been described previously, variety pedunculatum, occurring north of Townsville, and variety curvicaule for plants between the Connors Range south of Mackay and Annan River, south of Cooktown. In this multivariate analysis of 107 representative plants sampled from areas between St Lawrence and Cooktown, cluster analysis and principal coordinates analysis, were used to categorise the variation. Three overlapping varieties are revealed. North of Townsville variety pedunculatum intergrades with a medium-to-tall rainforest form, which separates with a small overlap in analyses from variety curvicaule plants south of Townsville. We formally describe these rainforest forms, previously referred to as variety curvicaule, as a new variety, Dendrobium speciosum variety boreale, which occurs between Cooktown and Mt Elliot, south of Townsville. Variety boreale is characterised by the presence of a collum in most individuals, medium to long pseudobulbs, large, wide leaves, long pedicels, and fairly uniform off-white to cream flowers. Dendrobium speciosum variety curvicaule Bailey is shown to be a name of uncertain application, and is neotypified to apply to the southern group of north Queensland plants, which occur between St Lawrence and Mt Dryander and on the Whitsunday Islands. Variety curvicaule is characterised by pseudobulbs that are of medium length, wide base and have an inconspicuous collum. The flowers have relatively wide segments in relation to all other varieties, long wide petals and incurving lateral sepals.

Abstract:

A repeatable index of population density for cane toads active around permanent water in the dry season showed that, in the lowlands of the Gulf of Carpentaria, local populations rapidly increased in size following colonization, and remained high (up to 2138 ha-1 on a single night) for at least 19 years. Long-established populations ( ~ 47 years) around Townsville have declined to an average density of 82 ha-1 on a single night. In this area toads are in poor body condition, are smaller, and have a lower proportion of reproductive males than do younger populations. The sizes of fat bodies, and the numbers of ova carried by females, do not appear to have declined in the Townsville populations. The index of population density was found to represent approximately 20% of a Jolly-Seber, capture-recapture estimate of population density for a 2.5-year-old cane toad population. The Jolly-Seber estimate for this young population is up to 45 times the densities of native cane toads in Panama. The numbers of toads captured, toad body sizes and proportions of sexually mature toads in the Townsville populations are very similar to those in Panama.

Abstract:

Abstract We reassessed whether two parapatric non-sister Australian honeyeater species (Aves: Meliphagidae), varied and mangrove honeyeaters (Gavicalis versicolor and G. fasciogularis, respectively), that diverged from a common ancestor c. 2.5 Mya intergrade in the Townsville area of north-eastern Queensland. Consistent with a previous specimen-based study, by using genomics methods we show one-way gene flow for autosomal but not Z-linked markers from varied into mangrove honeyeaters. Introgression barely extends south of the area of parapatry in and around the city of Townsville. While demonstrating the long-term porosity of species boundaries over several million years, our data also suggest a clear role of sex chromosomes in maintaining reproductive isolation.

Abstract:

Objective: To analyse trends in length of hospital stay before and after the implementation of the Community Rehabilitation Northern Queensland Service (CRNQ) in Townsville, Australia. Design: Retrospective analysis of collected administrative data provided by the data custodian Townsville Hospital Health Service District. Setting: All patients discharged from the Townsville hospital between 1 July 2008 and 30 June 2013 for whom the Australian Refined Diagnosis Related Groups were stroke (B70), degenerative nervous system disorders (B67) or rehabilitation (Z60). Main outcome measures: Average length of stay and total number of inpatient episodes coded stroke, degenerative nervous system disorders or rehabilitation. Results: Length of stay for the selected diagnosis related groups was consistently ranging from 23 days to 25 days for the period 2008-2012. In the first year of full operational capacity of CRNQ (2012-13), there was an average reduction of six days in length of stay. The major reductions in length of stay occurred in patients admitted for rehabilitation care. Conclusions: This study adds additional evidence that earlier discharge can be facilitated for patients with neurological conditions living outside metropolitan areas when appropriate rehabilitation services are available in the community. Abbreviations: AR-DRG – Australian Refined Diagnosis Related Groups; CRNQ – Community Rehabilitation Northern Queensland Service.

Abstract:

We evaluated the use of telehealth for patients who had suffered a cardiac or respiratory arrest, and were medically coordinated from the Queensland coordination hub at Townsville. We conducted a review of all cardiac or respiratory arrest cases where teleheath had been used prior to aeromedical retrieval. The doctors involved in the cases completed an evaluation form about the use of telehealth during the resuscitation. During the 12-month study period 6460 patients were medically coordinated from Townsville. Telehealth was used 51 times, i.e. for 0.8% of all transfers. Of the 51 uses of telehealth, nine were for patients having a cardiac/respiratory arrest, i.e. 18% of telehealth use at Townsville was for patients undergoing resuscitation following cardiac or respiratory arrest. All eight medical coordinators and three of eight referring doctors responded to the survey. Most medical coordinators stated that telehealth assisted communication and aided assessment. Most medical coordinators and some referring doctors felt that it improved the quality of patient care. The free text comments on telehealth use for remote area resuscitation were generally very supportive. While the telehealth equipment was easy to use, minor audio problems reinforce the need for systems to be wholly reliable. A set of guidelines to aid future telehealth assisted resuscitation was produced. The present study suggests that telehealth use is beneficial during active resuscitation efforts.

Full text

Abstract:

The effect of legume species, used for augmentation of native perennial grasses, upon forage production and quality and animal production was studied over 4 vears in the semi-arid troPics of northwestern Australia. The legumes were Stylosanthes humilis cv. Paterson (Townsville stylo), S. hamata cv. Verano (Caribbean stylo) and a mixture of perennial species S. scabra cvv. Fitzroy and Seca and S. viscosa (perennial stylo). They were compared at 2 levels of fertility, unfertilised (UF) and with small inputs of superphosphate (F); and at stocking rates of 0.45,0.6 and 0.75 steers/ha for UF and 0.6, 0.8 and 1.0 steers/ha for F. By 1980 only half of the 3 x 12 treatments persisted, 3 Townsville stylo, 9 Caribbean stylo and 6 perennial stylo. Without fertiliser the perennial stylos had the highest wet season yields of 1-2 t/ha which constituted 4040% of pasture yield, compared with 2-20% for the other legumes. Caribbean stylo yields were highest with fertiliser, yielding 2-4 t/ha and 50-90% of the pasture at the end of the wet season, compared with 60-70% for perennial stylo and 5-30% for Townsville stylo. Anthracnose devastated Townsville stylo, and also reduced the productivity of Fitzroy. The perennial stylos had the highest concentrations of nitrogen (N), phosphorus (P), and sulfur (S) during the dry season while Caribbean stylo and its associated grasses had the lowest P and S concentrations during the wet season. When annual liveweight gains for each legume were compared at the same stocking rate-fertiliser level, differences were less than 15 kg, but there were considerable differences in the patterns of growth within the year; these differences were related to the seasonal availability and relative palatability of grass and legume. The overall mediocre animal growth of 30-110 kg/steer.year was attributed to the inadequate supply of nutrients for most of the year, with the possible exception of N.

Abstract:

A retrospective analysis was made of a cohort of patients who presented sequentially with acute ophthalmological conditions which were managed by telemedicine consultation. Twenty-four patients presented with acute problems requiring specialist ophthalmological advice to the emergency department of a remote hospital in Mt Isa, Queensland, between December 1996 and February 1997. Tele-ophthalmology consultations were carried out with three ophthalmologists working in a specialist eye clinic in Townsville, 900 km away. Patients and doctors were extremely positive about the telemedicine facility. Tele-ophthalmology was an effective means of providing acute specialist consultation in a remote emergency department. By reducing the need for acute transfers to the tertiary hospital in Townsville, significant benefits can be anticipated—both financial and in terms of convenience for the patient. Benefits for medical staff in skills acquisition and education were also evident.

Full text

Abstract:

Eleven species of butterfly from five families were collected from the flowers of A. bidwillii during November 1981 at Townsville. Most butterflies (c. 60-75%) from all families spent less than 30 s on blossoms, although some spent more than 2.5 min. Of 58 butterflies examined for pollen loads, 26 (44.8%) carried Acacia pollen. The number of polyads carried ranged from 1 to 10 with the majority being carried on the underside of the thorax and abdomen. Only two polyads were detected on the wings of a single Acraea andromacha andromacha (Fabricius) (Nymphalidae) and no butterflies carried pollen on the antennae. Considering the short periods generally spent in foraging and the low numbers of polyads carried by the butterflies in comparison with other insects collected from A. bidwillii, the butterflies are not regarded as important pollinators of the plant at Townsville.

Full text

Abstract:

In February 2019, a major flooding event occurred in Townsville, North Queensland, Australia. Here we present a prediction of the occurrence of mosquito-borne diseases (MBDs) after the flooding. We used a mathematical modelling approach based on mosquito population abundance, survival, and size as well as current infectiousness to predict the changes in the occurrences of MBDs due to flooding in the study area. Based on 2019 year-to-date number of notifiable MBDs, we predicted an increase in number of cases, with a peak at 104 by one-half month after the flood receded. The findings in this study indicate that Townsville may see an upsurge in the cases of MBDs in the coming days. However, the burden of diseases will go down again if the mosquito control program being implemented by the City Council continues. As our predictions focus on the near future, longer term effects of flooding on the occurrence of mosquito-borne diseases need to be studied further.

Full text

Abstract:

Genetic analysis of cold tolerance was applied to samples of recently collected isofemale strains of Drosophila melanogaster and D. simulans from natural populations from diverse climates. The temperate zone locality of Melbourne was sampled twice for both species, once in 1986 and again in 1987. In 1987, D. melanogaster collections were also made in the humid tropics at Townsville and the wet/dry tropical locality of Darwin. D. simulans was also collected in Townsville in 1987 but it was not found in Darwin. Diallel analysis was performed for each population sample, so there were seven diallels, each with from 9 to 12 strains which were randomly chosen. Diallel analyses showed that cold tolerance was mainly controlled by additive genetic effects. This pattern was consistent across time, across populations and across species. It is proposed that natural populations of both members of the sibling species have the genetic architecture necessary for adaptive phenotypic response to selection by intermittent periods of low temperature.

Full text

Abstract:

The biology of 835 specimens of Galeocerdo cuvier caught between 1964 and 1986 off Townsville, Australia, was examined. The sharks were caught in a protective meshing programme using both large mesh gill-nets and set lines. The size at birth was estimated to be 80-90 cm total length, and females matured at approximately 287 cm total length. Litter sizes ranged from 6 to 56. Breeding and pupping both appear to occur in summer, with females not breeding every year. Mature females possibly migrate inshore during late spring and summer to give birth. The sex ratio of juveniles and adults favoured females, with few adult males being caught. Ontogenic changes in the diet were observed, with juveniles feeding predominantly on teleosts, sea snakes and birds and adults mostly consuming teleosts, sea snakes, turtles and crabs. There was no apparent decrease in the population size of G. cuvier in the Townsville area as a result of the long-term catching of sharks by the protective meshing programme.

Abstract:

AbstractPhysiological dormancy of scarified seeds of Townsville stylo (Stylosanthes humilis HBK) was released by acidic aluminium (Al3+) solution. Antiethylenic substances inhibited germination of low-pH-stimulated dormant seeds, with a correspondingly low ethylene production and low activity of 1-aminocyclopropane-1-carboxylate (ACC) oxidase in seeds. On the other hand, antiethylenic substances did not decrease the germination of Al3+-stimulated seeds, but ACC oxidase activity and ethylene production by the seeds was decreased to a large extent. These data provide evidence that dormancy breakage by Al3+ differs from that caused by low pH and is not associated with ethylene production. Similarly to Al3+ action, methyl viologen (MV), a reactive oxygen species-generating compound, broke dormancy of Townsville stylo seeds. Sodium selenate and N-acetyl cysteine, antioxidant compounds, largely decreased germination of MV- and Al3+-stimulated dormant seeds. Altogether these data point to oxidative radicals constituting key molecules in the chain of events triggered by Al3+ leading to dormancy breakage.

Abstract:

The extent of variation for host disease reaction and pathogen virulence was studied in naturalized populations of Stylosanthes hurnilis and Colletotrichurn gloeosporioides, the causal fungus of an anthracnose disease of Stylosanthes spp. Diseased plants (S0) were collected from the field at three sites (Townsville, Wrotham Park and Niall) in North Queensland, and first generation selfed (S1) progenies (host-lines) and single spore fungal cultures were grown for each of the collections made. Within a site, all host-lines were inoculated with each fungal isolate from that site, and a fourth experiment was conducted with representative host-pathogen combinations from each site. Sufficient seed was obtained to allow testing of 12, 10 and 8 collections from Niall, Wrotham Park and Townsville respectively. Significant variation (P < 0.01) between disease severity values for host-line means, fungal isolate means and host-line/fungal isolate interactions was found in all four experiments. Differences between fungal isolate means were the main source of variation in three of the four experiments. Both the differences in virulence within the pathogen population and the differences in resistance of the hostlines appeared to be quantitatively inherited. One host-line from Wrotham Park was significantly more resistant than the susceptible check, cv. Paterson, in two replicated experiments indicating that selection for some improvement in resistance within the naturalized populations should be possible. However, none of the host-lines from the Townsville and Niall sites were significantly more resistant than Paterson, suggesting that little natural selection for resistance has occurred within the naturalized host populations over the 10 years following the first outbreak of the disease in northern Australia.

Abstract:

The use of stolons in competitive interactions between several species of bryozoans growing in Townsville Harbour, North Queensland is described. Stolonal growth resulted in overgrowth reversals and redirected growth in interactions between Schizoporella unicornis and Watersipora subtorquata. These results suggest that stolons may play an important role in bryozoan interactions

Abstract:

In a large-scale grazing experiment in the Monsoon Tallgrass savannas of the Northern Territory, Townsville stylo (Stylosanthes humilis), Caribbean stylo (S. hamata) and perennial stylo (S. scabra + S. viscosa) were sown into native pasture and grazed at three stocking rates, under two fertilizer rates and with trees killed and unkilled. These treatments, together with the occurrence of anthracnose, led to the rapid decline in both yield and numbers of plants in those pastures sown to Townsville stylo. In contrast, yields of Caribbean stylo and Perennial stylo stabilized after three years in both fertilized and unfertilized swards. While total legume yield of these latter two treatments was similar, the dominant contribution in Caribbean stylo was made by annual plants, while in Perennial stylo swards individuals more than 18 months old contributed 80% of the yield.There were marked differences between all species in their population biology. Townsville stylo declined in numbers with death of individuals prior to seed set and the rapid depletion of the soil seed pool which had little long-lived seed. In contrast, in swards of Caribbean stylo a large amount of hard seed rapidly built up in the soil seed pool and ensured continuity of productivity even if seed was not set in some years. In the perennial stylos, seed softened quickly, and the soil seed pool remained small and short-lived. In these latter Stylosanthes spp., long-term stability depended on the survival of perennating plants rather than seed.Pasture management must take into account these different patterns of population dynamics. In particular, while fire is a potentially useful tool in renovating Caribbean stylo swards with their large soil seed pool, it can be extremely detrimental to perennial stylo swards where individuals are susceptible to burning and there is little soil seed available to re-establish the sward.

Abstract:

D. melanogaster populations from the fluctuating temperate climate of Melbourne (38�S) and in the tropics at Townsville (19�S) were investigated for differentiation in cold tolerance and desiccation tolerance, and were found to differ as predicted a priori from climatic considerations. Flies from the former locality were more tolerant to both of these environmental stresses. In comparable D. simulans populations, there was no significant differentiation between populations for cold tolerance or desiccation tolerance. In both species, there was genetic variation within each population. It is hypothesised that the non-parallel patterns in these sibling species may be due to different genetic strategies in temporal variation for tolerance to the stresses associated with climatic extremes. For D. melanogaster and D. simulans, there was no strong association between cold tolerance and desiccation tolerance in either the Melbourne and Townsville populations. Correlations between the stresses over the 15 strains were calculated for the sexes, generations, localities and species separately and were all non-significant. Cold tolerance and desiccation tolerance thus involve different physiological mechanisms.

Abstract:

This study serves to clarify the current status of canid and felid Ancylostoma species present in Australia. The morphological identification of A. ceylanicum from cats for the first time in Townsville, Australia, appears to be in error, together with the genetic markers provided for the species. Morphological and genetic data presented herein provide strong evidence that the hookworms from cats in Towsville are not A. ceylanicum as previously identified (i.e. the first report of this species in Australia), but are A. braziliense. Therefore the subsequent genetic markers established for A. ceylanicum in subsequent molecular studies based on these Townsville specimens should also be attributed to A. braziliense. Based on this information, a study of canine hookworm species present in northern India is also in error and it is apparent that the hookworms found in this region are those of A. ceylanicum. The distribution of A. braziliense and A. ceylanicum in the Americas and Asia Pacific region is discussed together with the importance of combining parasite morphology with genetic data for parasite diagnosis in epidemiological studies.

Full text

Abstract:

Within Australia the northern short-nosed bandicoot, Isoodon macrourus, occurs in coastal areas from the Kimberleys to the monsoonal tropics of the Northern Territory and from Cape York Peninsula to the Hawkesbury River, New South Wales (Gordon 1983). The reproductive ecology of I. macrourus has been studied in two captive (Hall 1983; Gemmell 1988) and five natural populations (Gordon 1971, 1974; Gemmell 1982; Hall 1983; Friend 1990; Kem- per et al. 1990; Budiawan 1993). Three of the latter (Darwin, the Mitchell Plateau and Townsville) were in the tropics; breeding at these sites occurred dur- ing the wetter months of the year but not during the summer of 1982/3 in Darwin when the monsoon failed (Friend 1990) or during the relatively dry winter/spring of 1991 in Townsville (Budiawan 1993), suggesting a dependence on rainfall (Friend 1990; Budiawan 1993). We report on differences in the reproduction, growth and development of I. macrourus in Rockhampton, Queensland, from March - October 1993 at four adjacent sites which received different amounts of artificial watering.
