Abstract:
Shiny Nematolepis Nematolepis wilsonii is a small understorey tree endemic to Victoria, south east Australia. The species is listed as threatened due to its limited distribution and low abundance. The sole known population, of approximately 400 metres individuals, is located in the Yarra Ranges National Park, Victoria. Paired exclusion plots were erected to investigate the impact of antler rubbing and thrashing activities of Sambar Cervus unicolor on Shiny Nematolepis. Sambar rubbing activities removed, on average, over half the circumference of bark down to the cambium of mature trees. Rubbing damage covered a range of tree sizes, with rubbed individuals in significantly poorer health and exhibiting 19% less relative foliage cover than non-rubbed individuals. Saplings selected by Sambar for thrashing had a significantly greater stem diameter and were most commonly situated beside the road. Other forms of damage to Shiny Nematolepis included storm events and biting by Yellow-tailed Black Cockatoo Calyptorhynchus funereus, but Sambar pose an added threat, which is likely to result in further decline of this threatened population.

Abstract:
AbstractThis study assessed the level of community awareness and participation in ecotourism in Old Oyo National Park, Nigeria. Data were collected in communities located in four ranges (i.e. administrative and protection zones) of Old Oyo National Park, Oyo State, Southwest Nigeria. The ranges are Tede, Marguba, Sepeteri, and Oyo-Ile. Seven (7) communities out of 27 that are in Tede range were selected, eight (8) were selected from 12 communities in Marguba range, eight (8) were selected from 17 communities in Sepeteri range while eight (8) were selected from 30 communities in Oyo Ile range. The study was a questionnaire survey involving 150 respondents that were randomly selected from communities in the four (4) ranges of the Park. Data were analysed using descriptive statistics, one way analysis of variance (ANOVA) with Tukey’s HSD, t-test and logistic regression. Results revealed that 48% of the respondents were aware of ecotourism while 52% were not. Also, 46% participated in ecotourism while 54% did not participate. A relationship exists between ecotourism awareness and participation (p<0.01). Community type (p<0.01) was the only predictor of community awareness of ecotourism while community type (p<0.01) and awareness (p<0.01) were the predictors of participation in ecotourism in the park. Awareness, active involvement of communities in stakeholder meetings, decision-making and provision of start-up capital are important for ecotourism development in the park.

Abstract:
Description of the ecological niche feral horses fill in Theodore Roosevelt National Park requires information on reproductive rates, home range size, individual and band affinity to home ranges, food and shelter requirements and seasonal diets. Therefore, the initial objectives will be to: 1. identify the number, size and location of home ranges for harem and bachelor stallion bands; 2. describe daily and seasonal movements of bands within identified home ranges; 3. describe the vegetation habitat types and landform types used by horses for mating, foaling, foraging, and resting cover; 4. describe seasonal horse diets; and 5. collect data on sex, age and social hierarchy within respective bands to facilitate estimation of horse population growth rates. Ultimately, this information will be used to accomplish the project goal; integrate horse requirements with those of elk, bison and the Park's vegetation communities to determine the large ungulate carrying capacity of Theodore Roosevelt National Park.

Abstract:
The Australian endemic humicolous and hygropetric water beetle genus Tympanogaster Perkins, 1979, is revised, based on the study of 7,280 specimens. The genus is redescribed, and redescriptions are provided for T. cornuta (Janssens), T. costata (Deane), T. deanei Perkins, T. macrognatha (Lea), T. novicia (Blackburn), T. obcordata (Deane), T. schizolabra (Deane), and T. subcostata (Deane). Lectotypes are designated for Ochthebius labratus Deane, 1933, and Ochthebius macrognathus Lea, 1926. Ochthebius labratus Deane, 1933, is synonymized with Ochthebius novicius Blackburn, 1896. Three new subgenera are described: Hygrotympanogaster new subgenus (type species Tympanogaster (Hygrotympanogaster) maureenae new species; Topotympanogaster new subgenus (type species Tympanogaster (Topotympanogaster) crista new species; and Plesiotympanogaster new genus (type species Tympanogaster (Plesiotympanogaster) thayerae new species. Seventy-six new species are described, and keys to the subgenera, species groups, and species are given. High resolution digital images of all primary types are presented (online version in color), and geographic distributions are mapped. Male genitalia, representative spermathecae and representative mouthparts are illustrated. Scanning electron micrographs of external morphological characters of adults and larvae are presented. Selected morphological features of the other members of the subtribe Meropathina, Meropathus Enderlein and Tympallopatrum Perkins, are illustrated and compared with those of Tympanogaster. Species of Tympanogaster are typically found in the relict rainforest patches in eastern Australia. Most species have very limited distributions, and relict rainforest patches often have more than one endemic species. The only species currently known from the arid center of Australia, T. novicia, has the widest distribution pattern, ranging into eastern rainforest patches. There is a fairly close correspondence between subgenera and microhabitat preferences. Members of Tympanogaster (s. str.) live in the splash zone, usually on stream boulders, or on bedrock stream margins. The majority of T. (Hygrotympanogaster) species live in the hygropetric zone at the margins of waterfalls, or on steep rockfaces where water is continually trickling; a few rare species have been collected from moss in Nothofagus rainforests. Species of T. (Plesiotympanogaster) have been found in both hygropetric microhabitats and in streamside moss. The exact microhabitats of T. (Topotympanogaster) are unknown, but the morphology of most species suggests non-aquatic habits; most specimens have been collected in humicolous microhabitats, by sifting rainforest debris, or were taken in flight intercept traps. Larvae of hygropetric species are often collected with adults. These larvae have tube-like, dorsally positioned, mesothoracic spiracles that allow the larvae to breathe while under a thin film of water. The key morphological differences between larvae of Tympanogaster (s. str.) and those of Tympanogaster (Hygrotympanogaster) are illustrated. New species of Tympanogaster are: T. (s. str.) aldinga (New South Wales, Dorrigo National Park, Rosewood Creek), T. (s. str.) amaroo (New South Wales, Back Creek, downstream of Moffatt Falls), T.

Abstract:
Management of elk on the northern winter range of Yellowstone National Park has remained a controversial subject through most of this century (Singer 1989). Until 1968 elk were artificially controlled because it was believed that ranching outside the park excluded elk from winter ranges resulting in unnaturally high populations in the Park and uncontrolled elk numbers would result in overgrazing and ecosystem degradation. However, in 1968 elk reductions were terminated and by 1971 a hypothesis of natural regulation was formulated by Park biologists (Singer 1989). The natural regulation hypothesis asserts that the Yellowstone area used by elk is an ecologically complete habitat (all required components of the habitat are present) and that density dependant factors will limit population growth of elk without major range degradation.

Abstract:
Although it is generally acknowledged that fire-induced heterogeneity is important for maintaining diverse species assemblages in northern Australian savannas, scant relevant data are currently available to examine this proposition. The study takes advantage of a singular, detailed, bidecadal fire history assembled annually for Kakadu National Park to explore relationships between fire-induced heterogeneity and other terrain features. Three patch-based heterogeneity indices were calculated from assembled fire-history data for the central 1-ha cell of a 5 × 5 cell (25 ha) window; that is, at a spatial scale relevant to the home ranges of many small- to medium-sized native mammals. Two of these indices were first calculated separately for each year, employing different metrics based on the extent of burning occurring in the 5 × 5 cell array, and then averaged for each of four consecutive five-year periods and over all years. The third index was calculated as the sum of the coefficients of variation for four fire-regime variability parameters determined likewise for five- and 20-year periods. Assembled data illustrate that (1) fire-induced heterogeneity in Kakadu increased in each successive five-year period from 1981, and (2) when modelled with independent terrain coverages, significant relationships were obtained for all three heterogeneity indices with terrain roughness, distance to roads, and distance to drainage lines.

Abstract:
Extensive riparian plant communi ties dominated by willow provide important wildlife habitat within and adjacent to Grand Teton National Park. High densities of noose are often associated with these willow comununities. I studied the habitat relationships of the Jackson Hole moose from 1964-69 (Houston, 1968, 1969). Findings suggested that although moose browsing influenced the structure and appearance of preferred willow species, their foraging did not cause progressive deterioration of these plants on major winter ranges. Here I report results from continued low level nonitoring to evaluate these earlier interpretations.

Abstract:
Abstract Human population growth near protected areas often results in detrimental edge effects for apex carnivores, such as the African lion. Urbanization leads to new scenarios of the human–lion conflict, thus understanding ranging patterns close to urban environments is crucial to inform future management strategies. We collected GPS data from 12 collared lions between 2014 and 2018 in Nairobi National Park, which borders the capital city of Kenya, Nairobi city. We estimated home ranges, calculated daily distance traveled and tested for differences between sex, season and pride. Additionally, we investigated how disturbance from Nairobi and surrounding human settlements affected space-use of lions, and tested for differences between sex, season and time of day. Lions showed restricted movements (4.5 km/day) and had small home ranges (49 km2). Male lions had larger ranges than females, but avoidance behavior of disturbed areas was similar. Lions took advantage during times of low human activity, i.e., during the night, to extend ranging behavior in search for resources. Risk for livestock depredation also increased during the wet season when lions roamed longer, more frequently, and deeper into the community lands. We recommend the establishment of buffer zones to maintain a viable lion population and reduced risk for conflict.

Abstract:
The buffer zones of Nigerian protected areas are poorly managed. Patas monkey (Erythrocebus patas) was studied in fact owing to its dearth of information on its ecology and existence in South-West Nigeria National Park. Therefore, it was necessary to examine E. patas spatial distribution and population structure in the Old Oyo National Park buffer zone ranges, situated in South-West Nigeria and as well know its dietary uptake alongside delineating its various activities. Observations were positioned on direct census methods. A total of 60 individuals of E. patas (23 female, 21 male, and 16 young individuals) were sighted within the study period (March to July). The results showed that the highest number of sighted E. patas (18 individuals) was recorded in the month of March while the Marguba range had the highest percentage of sighted E. patas (31.7%). Thirteen plant species were identified as food matters of E. patas while the major activity observed by the majority of E. patas was found feeding on the identified food matters. The food matters consumed were plant parts which included the leaves, flowers, gum, enflamed spikes, and fruits. Actions to uphold and guard the remaining populace of E. patas in the Park and buffer zones should be adequately fortified.

Abstract:
Summer range is not thought to be limiting to elk because abundant, high quality forage is available whereas a shortage of forage usually exists on elk winter ranges. Nevertheless, summer nutrition and fat reserves acquired on summer ranges influence growth, survival and reproduction of ungulates (Klein 1965, Verme 1963, 1965, Julander et al. 1961). The enormous area of summer range for the Northern Yellowstone elk herd renders detailed field surveys impractical. This study was initiated to evaluate the feasibility of using LANDSAT satellite imagery to (1) characterize vegetation communities on summer range from LANDSAT multispectral scanner (MSS) data and digitized vegetation maps of Yellowstone National Park, (2) predict plant production within grassland types and (3) correlate elk population characteristics with fluctuations in plant production and weather.

Abstract:
Parma wallabies (Macropus parma) have a patchy distribution on the coast and ranges of central and northern New South Wales from Goulburn northward to the Queensland border. In Gibraltar Range National Park they are found in dry sclerophyll forest with a heath understorey, a departure from their apparent preference for wet forest types. Distance to swamp was by far the best correlate of M. parma distribution.

Abstract:
SUMMARYResults are presented from a number of epidemiological studies using enzyme immunoassays (EIA) based on the purified anthrax toxin antigens, protective antigen, lethal factor and oedema factor. Studies on sera from a group of 62 human anthrax patients in Turkey and from cattle in Britain following two unrelated outbreaks of anthrax show that EIA using protective antigen can be a useful diagnostic aid and will detect subclinical infections in appropriate circumstances. A serological survey on wildlife in the Etosha National Park, Namibia, where anthrax is endemic, showed that naturally acquired anthrax-specific antibodies are rare in herbivores but common in carnivores; in carnivores, titres appear to reflect the prevalence of anthrax in their ranges. Problems, as yet unresolved, were encountered in studies on sera from pigs following an outbreak of anthrax on a farm in Wales.Clinical details, including treatment, of the human and one of the bovine outbreaks are summarized and discussed in relation to the serological findings.

Full text
Abstract:
The factors that affect the trappability of the red fox (Vulpes vulpes L.) in alpine and subalpine New South Wales were examined by means of treadle snares. Trapping (1) on animal tracks without the use of a bait or lure, and (2) by setting snares around a bait, led to the capture of individuals of both sexes and all age-classes. A greater number of foxes was captured per number of snares set in winter than in other seasons because of the commensal foraging patterns of foxes at this time. Foxes were more likely to be caught within 100 m of their home-range boundaries during snow-free months and outside their home ranges while foraging at ski resorts in winter. Snares were found to be difficult to set, and foxes were captured in only 50% of sprung snares. Treadle snares caused no apparent long-term injuries to 40 red foxes that were radio- tracked and observed for 1–24 months after capture.

Abstract:
Abstract The purpose of this paper is to present selected methods of evaluation of thermal conditions in the Wielkopolski National Park and their initial characterization. The analysis was based on data from the automatic meteorological station in Jeziory measured during the period 2001-2010. The calendar of thermal classes graphically shows the variation in thermal conditions for each month and deviation from the standard adopted for the period concerned (Table 2). A good complement to the calendar seems the graphs of mean daily air temperature for months above and below the standards that enable their connection with the peculiarities of weather occurring in the area of Central Europe (Fig. 1). In addition to complete characterization of thermal conditions, specific number of days according to the average daily temperature ranges (Tavr): tavr. < 10°C, tavr. 10.1-15.0°C, tavr. 15.1-20.0°C, tavr. 20.1-25.0°C, tavr. 25.1-30.0°C and interdiurnal changes of average daily temperature (ΔTavr): Δtavr. < 2°C, Δtavr. 2.1-4.0°C, Δtavr. 4.1-6.0°C, Δtavr. >6.0°C were calculated (Table 3, 4). They were the basis for separating the year into thermal seasons (Table 5, Fig. 2). Ward’s method was used giving the best results in the case while both Tavr and ΔTavr were taken into consideration. The results obtained allow concluding that different methods of evaluation of thermal conditions applied separately do not give a full picture of thermal conditions of the area. Only a combination of results obtained using the Ward’s and calendar methods can give a complete thermal conditions characterization.

Abstract:
AbstractThe Vulnerable fosa Cryptoprocta ferox is the largest native carnivore in Madagascar, fulfilling a unique ecological niche in the island's remaining forests. Negative interactions with humans threaten the long-term viability of most remaining fosa populations across Madagascar. Threats to the fosa include habitat loss and persecution by humans resulting from perceived predation on domestic animals. We used GPS collars to record space use and activity patterns of five fosas in Ankarafantsika National Park, Madagascar, during the dry seasons of 2016 and 2017. The results, with up to 2,110 recorded locations per individual, indicated fosas’ home ranges and movements were not limited to the forest, and all collared individuals used networks of habitat patches and corridors to navigate deforested areas. The fosas studied in Ankarafantsika National Park had significantly larger home ranges than those reported in previous studies in other protected areas. They were rarely found within village boundaries and appeared to avoid areas of human habitation, suggesting that during the study period livestock was not a significant component of the fosas’ diet in this Park. Our results suggest that fosas have some flexibility that enables them to adapt to living near deforested and human-dominated areas by altering their space-use patterns, but they are compensating by increasing their home range size.

Abstract:
The study was conducted in Kafta-Shiraro in Northern region of Ethiopia. The study uses two important parameters to realize the objective of the study investigating themanagement and integration of the park, one is studying and explaining the community perceptions towards elephant (flagship species) conservation in Kafta Shiraro National Park (KSNP) and secondly compare and contrast the population structure and density of the (economically important plant) Boswellia papyrifera (Del.) Hochst inside and outside of the protected areas and the study contribute to the scientific bases for improved management of biodiversity and its conservation system. A total of 100 households were selected from 10 villages using a stratified random sampling. A rapid vegetation assessment survey was conducted in two Boswellia stands, inside the park and outside the park at villages in order to examine the status of the resource base. A total of 40 sample plots of size 20 X 20 m were laid at regular interval along parallel transects with smaller sample plots of size 5 X 5 m nested in the center of each plot for regeneration count. The conflicts between humans and wildlife in KSNP have been getting worse over time and underline the need to find a workable solution to stop the progress of encroaching human activities that are core factors in the conflict. The underlying factors were found to be free encroachment into the wildlife home ranges, mainly for cultivation and dry wood collection. The factors that contributed to the poor conservation of African elephant included weak community awareness and understaffed anti-poaching and patrolling team of the KSNP. The improper land use by host settlers locally called “wefrizemet” as well as legal settlers maximizes the level of habitat disturbance (threat of the elephants in the park) due to illegal cultivation with high number of livestock crossing to the park. B. papyrifera population structure illustrates that natural regeneration is lacking in all two study areas. Additionally, the population of Boswellia in the study areas is unstable and under threat due to lack of recruitments through regeneration. Based on the stands structure analysis, it is hypothesized that lack of natural regeneration is primarily caused by livestock grazing pressure and the absence of recruitment is largely caused by lack of seed production by mother trees as the result of intensive tapping of the frankincense. KSNP is deteriorating due to a lack of integration and development cooperation between the Park and the surrounding local community as well as administration the minimal managerial and institutional capacity of the Park, minimal alternative livelihoods for the surrounding communities, inadequate commitment among all officials in taking the Park as an issue of development agenda, absence of legal procedures and understandings on expansion of large scale farms, unplanned and non-integrated land use systems, and a lack of appropriate outreach programs needed to change the attitudes of the surrounding communities. Collaborative Park management is urgently required to rescue KSNP; agreement should be made from National to Woreda level stakeholders.

Abstract:
Abstract:Locating activity hotspots – areas of higher density, more intense use, or distinct social units – is a prerequisite for answering many questions in animal ecology. However, for many species, carrying out such research from direct observations in tropical habitat is time-consuming and unrealistic for non-habituated animals. This study aimed to locate chimpanzee home ranges from transect nest counts. For validation purposes, 233 line transects were sampled within the home ranges of four habituated social groups of chimpanzees in Taï National Park, Côte d'Ivoire. In total, 373 km of transects were surveyed over 188 days and 683 nests of chimpanzee were recorded. First, we characterized heterogeneity of nest distribution patterns, including variation in density and group size within the area. Second, we used scan statistics, a likelihood-based cluster technique to locate chimpanzee social groups and compared them with the known home range boundaries. Chimpanzee nest distribution was characterized by a positive density and group-size gradient away from the range periphery. Furthermore, nest distribution clusters corresponding to the four groups could be successfully identified, although additional clusters for, for example, low-density areas between social groups seem to be an unavoidable by-product. The approach taken can be extended to a wide spectrum of data stemming from direct observations, camera traps, acoustic or genetic sampling to derive information about structure and patchiness of wild animal populations.

Abstract:
The mountainous Kaokoveld of northwestern Namibia contains numerous endemic plants and animals whose ranges, in many cases, extend into the Etosha National Park, an area extremely rich in game. Etosha Pan, the most striking feature of the Park, is bordered on the South by natural springs and artificial waterholes. These provide drinking places for the animals which congregate in large numbers and cause overgrazing and browsing pressure in the area. Migration to regions beyond the Park boundary is prevented by an 850 km-long game-proof fence. The main factors affecting animal populations are anthrax and poaching. Even so, the culling of Elephants becomes necessary from time to time, and the sale of ivory and other products helps to finance the operation of the Park.

Abstract:
The Brisbane Ranges include areas of National Park, water catchment and freehold land that have a history of infection with the pathogen P. cinnamomi since the late 1960s. A systematic survey of the small-mammal fauna of the Brisbane Ranges National Park and the Geelong and District Water Board catchments in relation to the pathogen was carried out in 1987. A. stuartii was the only species trapped regularly. The volume of vegetation to a structural level of 60 cm was significantly lower at sites where P. cinnamomi was present. The abundance of A. stuartii was also significantly lower at sites infected with P. cinnamomi, and a significant relationship is shown between the capture rate of A. stuartii and the volume of vegetation present up to 40 cm above ground level. This work indicates a possible association between P. cinnamomi and populations of A. stuartii, and the relationships between the pathogen, habitat quality and small-mammal distribution are discussed. These findings have implications for public land management and management of fauna in areas prone to infection with P. cinnamomi.

Full text
Abstract:
The jaguar Panthera onca is threatened throughout its range and categorized as Near Threatened on the IUCN Red List. To inform conservation of the jaguar population in Corcovado National Park, Costa Rica, population size was estimated using data from a 3-month camera trap study. Individuals were identified from their coat patterns. The resulting density estimate of 6.98 ± SD 2.36 individuals per 100 km2 was lower than expected. The sex ratio was 1.33 males per female, and the minimum home ranges of two males were 25.64 and 6.57 km2. Hunting pressure on jaguar and white-lipped peccaries Tayassu pecari, the jaguar's main prey in the Park, may be responsible for the low jaguar density as space does not seem to be a limiting factor. The numbers of females may have been underestimated because of sampling bias and therefore the sex ratio obtained in this and similar studies must be interpreted cautiously. Better protection of the corridor that connects the Park with other protected areas is essential to guarantee long-term survival of the jaguar in Costa Rica.

Full text
Abstract:
The movements of a subalpine population of feral pigs were examined at Kosciusko National Park in southeastern New South Wales. Sufficient data were collected to estimate the home-range area of 20 pigs on the basis of 782 telemetry and trap locations. Mean (+/- s.d.) home-range size (minimum convex polygon method) for males (35.0 t 22.2 km*2) was significantly greater than that for females (1 1.1 +/- 5.2 km*2). Use of capture-recapture distances to estimate home-range size was considered inappropriate. A test for nomadism suggests that, although home ranges of pigs in this environment were larger than those reported for other pigs in Australia, the pigs were essentially sedentary. Management implications for this population are discussed.

Abstract:
The distribution of Phytophthora cinnamomi in the Brisbane Ranges National Park of Victoria was mapped and related to vegetation susceptibility, disease severity and past distribution. P. cinnamomi extended its distribution from 1% of the park in 1970 to 31% in 1980-81. The dispersal of the pathogen has occurred through roadworks and subsequent drainage of water-borne zoospores. In 1980-81, 50% of 1191 grids (250 x 250 m) occurred in susceptible vegetation (sclerophyllous forest/woodland). Of these, 45% (266 grids) were moderately diseased and 16% (95) severely diseased. Stands of dead trees occurred in 29 severely diseased grids which were in shallow gullies with impeded drainage. The 39% (231) of susceptible vegetation which remained unaffected occurred mainly on ridges and hilltops. P. cinnamomi was isolated from 3% of apparently resistant vegetation (graminoid forest/woodland). Restriction of access is recommended to the remaining areas of susceptible unaffected vegetation.

Full text
Abstract:
The Border Ranges fault system of southern Alaska, the fundamental break between the arc basement and the forearc accretionary complex, is the boundary between the Peninsular–Alexander–Wrangellia terrane and the Chugach terrane. The fault system separates crystalline rocks of the Alexander terrane from metamorphic rocks of the Chugach terrane in Glacier Bay National Park. Mylonitic rocks in the zone record abundant evidence for dextral strike-slip motion along north-northwest-striking subvertical surfaces. Geochronologic data together with regional correlations of Chugach terrane rocks involved in the deformation constrain this movement between latest Cretaceous and Early Eocene (~50 Ma). These findings are in agreement with studies to the northwest and southeast along the Border Ranges fault system which show dextral strike-slip motion occurring between 58 and 50 Ma. Correlations between Glacier Bay plutons and rocks of similar ages elsewhere along the Border Ranges fault system suggest that as much as 700 km of dextral motion may have been accommodated by this structure. These observations are consistent with oblique convergence of the Kula plate during early Cenozoic and forearc slivering above an ancient subduction zone following late Mesozoic accretion of the Peninsular–Alexander–Wrangellia terrane to North America.

Full text
Abstract:
Predicting the distribution of amphibians can be difficult because habitat suitability may depend on a variety of environmental and anthropogenic factors, including water quality of wetlands, geology of watersheds, and presence of invasive pathogens. Previous studies hypothesized that water chemistry may influence the rate of chytrid infection in amphibians where higher conductivity sites may have less infection. We sampled two watersheds in Grand Teton National Park and 3 watersheds adjacent to the park, and measured amphibian presence, chytrid infection, basic water quality, major ion concentrations and geology of the wetland. This is part of a larger project where we are comparing amphibian presence and infection rate among wetlands in the Gros Ventre, Wind River, and Teton Ranges. We sampled watersheds that were predominately limestone, granite or a mixture. Water quality varied among sites with higher conductivity and ion concentrations for limestone watersheds compared to granite watersheds. This report includes preliminary results of amphibian surveys and water quality analyses. Future analyses will relate occupancy rates of amphibians to environmental factors, including water chemistry, geology, and presence of chytrid fungus, as well as comparing detection rates of amphibians with environmental DNA (eDNA) and visual observation surveys.

Abstract:
The movements of marked honey possums,Tarsipes rostratus, were studied using mark–recapture with pitfall traps in heathland on the south coast of Western Australia. Most individuals moved less than 30 m even over several months, with no evidence of marked dispersal. We suggest that this lack of mobility is associated with a detailed knowledge of the locations of those plants that supply all the species’ food. Males moved slightly further than females, possibly to search for mating opportunities and possibly because females exclude males from rich nectar sources. In consequence, the home ranges of males (1277 m2) were significantly larger, on average, than those of females (701 m2).

Full text
Abstract:
How caribou (Rangifer tarandus), including Peary caribou (R. t. pearyi), use their annual ranges varies with changes in abundance. While fidelity to some seasonal ranges is persistent, use of other areas changes. Consequently, understanding changes in seasonal distribution is useful for designing boundaries of protected areas for caribou conservation. A case in point is the proposed Qausuittuq (Northern Bathurst Island) National Park for Bathurst Island and its satellite islands in the High Arctic of Canada. Since 1961, Peary caribou have been through three periods of high and low abundance. We examined caribou distribution and composition mapped during nine systematic aerial surveys (1961–2013), unsystematic helicopter surveys (1989–98), and limited radio-collaring from 1994–97 and 2003–06. While migration patterns changed and use of southern Bathurst Island decreased during lows in abundance, use of satellite islands, especially Cameron Island for winter range, persisted during both highs and lows in abundance. The northeast coast of Bathurst Island was used to a greater extent during the rut and during summer at low abundance. We suggest that Park boundaries which include Cameron Island and the northeast coast of Bathurst Island will be more effective in contributing to the persistence of Peary caribou on the Bathurst Island Complex.

Full text
Abstract:
Nine wild dogs, Canis f. familiaris, radio-tracked over periods of 28-61 days in Kosciusko National Park, N.S.W., occupied home ranges of 220-5420 ha (mean 2193 ha). These home ranges were similar in size to those observed for dingoes, C. f. dingo, in other areas of south-eastern Australia. The maximum distance that any of the nine dogs moved between successive daily locations was 11.2 km. On the basis of this information and that obtained by others, we suggest that the control of wild dogs on Crown Land in south-eastern Australia should be confined to those areas adjacent to private grazing land. Furthermore, a control zone 12-20 km wide should be adequate. Two successive trail-baiting campaigns with 1080 poison in March and April 1982 killed only two (22%) of the nine wild dogs carrying radio transmitters. Traps, in comparison, caught 15 out of 27 (56%) of the dogs known to be in the area. The main factors which reduced the success of the poisoning campaign were the rapid loss of toxicity of the baits after their distribution, the rapid rate at which they were removed by other animals, particularly foxes Vulpes vulpes and birds, and the dogs' apparent preference for natural prey.

Abstract:
The Upland Sandpiper (Bartramia longicauda) is a grassland shorebird species associated primarily with prairie habitats in central North America. A disjunct and poorly studied population also occurs in Yukon, Canada, and Alaska, United States. We studied habitat selection of nesting Upland Sandpipers in Ivvavik National Park, Yukon, at the scales of microhabitat (1-m radius around nest) and putative home range (11.3-m radius plots at nests and within 50 m of nest). At the microhabitat scale, the Upland Sandpiper selected nest sites with lower visibility from above than that of their home range (median 91.5%, range 70–98% versus median 99.0%, range 85–100%) and less-variable composition of vegetation than at random sites within the home range. Vegetation adjacent to the nest in the eastern quadrat was significantly shorter (mean ± standard error: 10.6 ± 1.55 cm) than that in other directions around the nest (> 13 cm); nest sites and microsites within home ranges were more often hummocky than random sites in the park. At the mesohabitat scale, Upland Sandpipers selected sites within home ranges with fewer trees than random sites within the park (10.3 ± 3.0 trees per 11.3-m-radius plot around nest versus 32.9 ± 5.9 trees per 11.3-m-radius plot in the park) and greater herbaceous cover (70.7% ± 3.0% versus 56.2% ± 3.7%). Despite the disproportionate use of sites with fewer trees, more herbaceous cover, and lower vertical visibility, these factors did not relate to nest success in our sample. Of the 24 nests found in 2010 and 2011, 22 contained four eggs and 2 contained three eggs. Upland Sandpipers at this high latitude site had a nesting success rate of 0.85 ± 0.01 and 0.56 ± 0.01 in 2010 and 2011, respectively, for a 21-day incubation period. Further assessment of the selected characteristics of nesting sites will improve our ability to predict the effects of northward shrub and tree encroachment on this grassland species.

Abstract:
Understanding habitat use of declining species is essential for their management and successful recovery. We examined habitat selection at multiple spatial scales by Northern Map Turtles ( Graptemys geographica (Le Sueur, 1817)), a species at risk, in the St. Lawrence Islands National Park, Ontario, Canada. At the scale of the home range, Map Turtles generally avoided deep water (>2 m) and selected home ranges in waters <1 m deep. Importantly, turtles used home ranges with significantly more natural than developed shoreline. At the scale of the location, adult females used deep water more often and males preferred areas with surface cover. Management efforts should implement regulations concerning further shoreline development.

Abstract:
We undertook a retrospective study of aspen age structure in the winter range of Jasper National Park to assess potential trophic cascades in wolf–elk–aspen systems. We compiled historical wolf ( Canis lupus Linnaeus, 1758) and elk ( Cervus elaphus Linnaeus, 1758) population data and, in 2005, sampled 42 trembling aspen ( Populus tremuloides Michx.) stands within the Palisades site along the Athabasca Valley near Jasper townsite and another 30 stands within the Willow Creek site in a relatively remote portion of the park. Results indicated that aspen recruitment (suckers or seedlings growing into tall saplings and trees) occurred at both sites in the early 1900s but decreased in the 1940s as elk numbers were reaching a maximum. Wolves were largely eliminated from the park in the mid-1900s, and aspen recruitment during that time ceased at both sites, apparently because of heavy browsing by elk. With recovery of wolf populations in the late 1960s and increasing predation risk, elk use of the Willow Creek site declined, and aspen recruitment resumed. However, at the Palisades site, an area of relatively low predation risk due to human use and developments, renewed aspen recruitment has not occurred. Results indicate that historical wolf or ungulate control programs and human developments influenced trophic cascades involving wolves, elk, and aspen in these winter ranges.

Abstract:
The pristine, protected ecosystem of Grand Teton National Park (GRTE) is the ideal location to study the relationships between butterfly populations and the habitats on which these insects depend. Two montane meadow butterfly species, Parnassius clodius and Parnassius smintheus, were investigated in this study to identify patterns of habitat occupancy relating to variables across GRTE and into the surrounding territory of Bridger–Teton National Forest (BTNF). Population dynamics of P. clodius have been intensively studied by our research group over several consecutive years in one isolated population in Grand Teton National Park. However, little has been investigated regarding the Parnassian butterflies’ population range across the GRTE ecosystem. For this study, presence-absence butterfly surveys were conducted across 45 meadow sites in preferred habitat during the Parnassius flight season (June – July 2013). We found that P. clodius occupied 80% of the meadows surveyed, which was far greater than was originally predicted. P. smintheus, the more rare Parnassian butterfly in the GRTE ecosystem, was only found at 9% of the meadows surveyed. Understanding population ranges and habitat limits of these butterfly populations will be useful for managers and scientists within GRTE, and will assist conservation efforts for other related Parnassian species that are threatened or endangered worldwide due to habitat loss and climate change.

Abstract:
We studied from 1993 to 2002 the spatial organization of visually marked females in an isard ( Rupicapra pyrenaica Bonaparte, 1845) population in the Pyrenees National Park. In winter, all individuals were concentrated within the same 3.7 km2 refuge area. In summer, two patterns of space use were recorded: sedentary females (n = 33; 52.2%) remained within the refuge area, whereas migrating females (n = 29; 46.8%) summered outside the refuge area, at a horizontal distance of 1.4–9.2 km and 300–800 m higher in elevation than their winter ranges. Females were faithful to their seasonal ranges. The population was organized in well-defined spatial units in summer. This organization was roughly preserved in winter, despite the spatial concentration of the individuals by this season. The resulting spatial clustering might reduce spatial competition and pathogenic contamination between groups, allowing the maintenance of high population density. The appearance of a migratory pattern occurred probably as a result of the protected status of the species, which allowed the population to increase. Some individuals dispersed as a result of the population density increase. The two recorded patterns of space use likely arose from spatial attachment and social affinity that developed in the first years of a female’s life, and could explain the coexistence of the two spatial patterns.

Abstract:
Human activities have fragmented amphibian habitats and affected amphibian diversity and distribution, but the ecology is poorly known. A four-year study assessed the diversity and distribution of amphibians in undisturbed and disturbed sites of the Kudremukh National Park (KNP), India. Iron-ore mining and associated activities in the KNP have induced habitat fragmentation. The disturbed sites had ranges of habitat variables clearly distinguishable from undisturbed sites. Thirty-six species of anurans and six species of caecilians have been recorded in the KNP and the total amphibian species richness represents 20% of the whole Indian amphibian fauna. Among these, 20 species were distributed in both disturbed and undisturbed sites, while 22 were found only in undisturbed sites indicating they may be threatened by further habitat fragmentation. Species diversity and richness formed two distinct groups clearly associated with disturbed and undisturbed habitats, respectively.

Abstract:
The population biology, habitat utilisation and diet of a small, isolated population of long-nosed bandicoots (Perameles nasuta) was studied over a 22-month period at North Head in Sydney Harbour National Park, New South Wales. Reproductive output in this urban environment was high, with a mean litter size of 2.3 and production of up to four litters per year. The peak of reproductive activity was in late spring and early summer, with a cessation of breeding in late autumn or early winter. The main causes of death were identified as road trauma (58% – probably an overestimate because of the ease of finding road deaths) and predation by cats and foxes (37% – probably an underestimate because of the difficulty of locating carcasses unless radio-collared). Bandicoots utilised all macrohabitats (open grassed areas, heath, forest, swamp and scrub), but extensively used open grassed areas for foraging. Males had larger home ranges (4.4 ± 0.8 ha) than females (1.7 ± 0.2 ha). The largest home ranges of males coincided with the peak of the breeding season (September–November). Throughout the year P. nasuta fed primarily on beetles, invertebrate larvae and ants, but also on other invertebrates and on plant and fungal material. Some vertebrate and human- derived material (birdseed, vegetable scraps, plastic, twine) was also eaten. Although remarkably adaptable in its reproductive and dietary strategies, this population of long-nosed bandicoots is likely to follow other urban bandicoot populations toward extinction unless there is active management to reduce the high rate of mortality from motor vehicles and introduced predators.
