Long-nosed fur seals (Arctocephalus forsteri) were tagged as pups in colonies on Kangaroo Island, South Australia in eight consecutive pupping seasons from 1988–89 to 1995–96. Thirty-nine tagged animals were sighted on the southern Australian coast, being 0.89% of those tagged. They were aged from 9 months to 14 years 6 months, with half in their second and third years. Most records (88%) were of animals that moved eastwards. The most distant records were from Sydney in the east (1700 km), south of Tasmania in the south (1240 km) and Head of Bight in the west (700 km). One animal was seen twice, both times on the north coast of Kangaroo Island, once underwater and two years later ashore. Satellite telemetry studies of juvenile A. forsteri from Kangaroo Island showed that they typically forage in pelagic waters ∼1000 km further south in association with the subtropical front. The study reported here shows that some animals tagged as pups disperse widely as juveniles around the southern Australian coast. The possibility of genetic interchange between breeding colonies is suggested by sightings of three tagged females aged 4 years and older at non-natal colonies.","PeriodicalId":55420,"journal":{"name":"Australian Journal of Zoology","volume":"6 1","pages":"173 - 179"},"PeriodicalIF":0.8,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81787597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phylogenetic relationships and estimated dates of origin, plus distributional, ecological and morphological data for salticid genera were used to examine a series of hypotheses related to the evolution of the Australian salticid fauna. Though independent, the time patterns of evolution of genera in Australia and South America were similar, while that for Northern Hemisphere taxa differed. In each case the production of new genera occurred during the warmer parts of the mid Tertiary but not during cooler and drier times. Asian elements entered Australia as early as 31 million years ago, long before the collision of the Australasian and Asian continental plates. Endemic and derivatives of Asian genera were similarly distributed across Australian biomes. However, arriving taxa were more successful when conditions matched their mesic origins (tropical), but less so when different (temperate). While endemic genera often extended their ranges into drier environments by increasing the number of species, recent arrivals did so by extending the range of individual species. Maximum Parsimony analyses of a range of presumed adaptive, morphological and ecological characters showed these did not reflect genus-level processes; however, the analysis did show all endemic genera had mesic origins.","PeriodicalId":55420,"journal":{"name":"Australian Journal of Zoology","volume":"37 1","pages":"162 - 172"},"PeriodicalIF":0.8,"publicationDate":"2020-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80581257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We monitored some aspects of maternal care in Australia’s second largest extant marsupial predator, the spotted-tailed quoll. We radio-collared six females carrying young at an early pouch stage in the Byadbo Wilderness in southern New South Wales in August–September 2016. When these young were deposited at a maternity den at a still altricial state we monitored den activity of the female and her young with motion-triggered camera traps. Lactating females remained in the same den for up to 39 days before moving to a new den, usually only a few hundred metres away. Females furnished dens with nesting material, but were never observed to carry prey nor were the young seen consuming solid food. They were also surprisingly tolerant towards visits and den use by wombats, rabbits, possums and male quolls. Females showed predominantly nocturnal activity, but usually returned at least once per night. Short daytime activity was also common. In contrast, juveniles were initially exclusively diurnal, probably to facilitate behavioural thermoregulation, and only later extended their playing and exploring towards dawn and dusk. Hence interactions between mother and young were rarely observed. Apparently, the young received little training from their mother and simply ventured further and for longer periods away from the den until independence.","PeriodicalId":55420,"journal":{"name":"Australian Journal of Zoology","volume":"13 1","pages":"145 - 152"},"PeriodicalIF":0.8,"publicationDate":"2020-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76136020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rises in abundance of a population in response to increased resources is often followed by a rise in predator abundance. The non-threatened eastern barn owl (Tyto alba delicatula) and the threatened eastern grass owl (Tyto longimembris) are predators that may have occupancy patterns linked with prey abundance. It is important to identify the resources that cause increases in primary prey items to further understanding of the ecology of these species. Here I test the hypothesis that grass seeds cause increased abundances of wetland-dwelling house mice (Mus musculus) in austral summer, and identify a wetland monocot that provides a food recourse to achieve this effect, as well as report eastern grass owl and barn owl observations. A 2.6 ha wetland area (on Kooragang Island, New South Wales) was surveyed almost weekly to quantify abundance of prey items from September to April for three years (2016–2019). Typha sp. (a monocot) had flowering periods that coincided with increases in house mouse observations (n = 90 in flowering, n = 2 in non-flowering), where 22% were detected feeding on Typha flowers/seeds or fleeing from flower stalks. Eastern grass owls were only observed during a Typha flowering period (n = 3). These observations confirmed the original hypothesis and led to the formulation of another hypothesis: wetland occupancy by eastern grass owls is influenced by Typha flowering. Future studies should aim to test this hypothesis and identify other wetland plants that provide an important food source for wetland-dwelling rodents.","PeriodicalId":55420,"journal":{"name":"Australian Journal of Zoology","volume":"8 1","pages":"210 - 214"},"PeriodicalIF":0.8,"publicationDate":"2020-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75635235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Koala scat surveys are important tools for determining koala presence and distribution in large forested areas where it is impractical to conduct direct observation surveys. However, current scat survey methods are problematic due to lack of either accuracy or feasibility, i.e. they are either biased or very time-consuming in the field. This study aimed to establish a new koala scat survey method with improved accuracy compared with existing methods, and practical in the field. We developed a new Balanced Koala Scat Survey method (BKSS), and evaluated it in the field by analysing scat detectability variations and comparing it with a current survey method, the Spot Assessment Technique (SAT), to determine scat searching accuracy. The results revealed that current methods were biased by assigning consistent searching effort for all trees, because effective searching time to detect the first scat was significantly affected by Koala Activity Level (KAL – the proportion of trees found with scats among all 30 trees in a survey site). Compared with BKSS, SAT tended to yield more false negative outcomes; SAT may miss up to 46% of trees with scats when KAL was low. The application of BKSS is expected to greatly enhance the reliability of koala scat surveys in determining koala distribution and thus improve their conservation management.","PeriodicalId":55420,"journal":{"name":"Australian Journal of Zoology","volume":"2 1","pages":"125 - 133"},"PeriodicalIF":0.8,"publicationDate":"2020-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86240575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dual-energy X-ray absorptiometry (DXA) is a non-invasive technology for measurement of body composition that requires validation against reference methods when applied to a new species. The aim of this work was to validate DXA for the assessment of body composition of the echidna. Body composition was determined in the short-beaked echidna (Tachyglossus aculeatus aculeatus) using a Norland XR36 DXA scanner and validated by proximate chemical analysis for dry matter, ash, crude fat (FM) and protein (as 6.25 × N) and bone mineral content (BMC). Echidnas were opportunistically obtained as ‘road kill’. Body composition data were compared between techniques by correlation and limits of agreement (LOA) analyses. Twenty-eight echidnas (11 males, 13 females, 4 not determined), weighing 520–5517 g, underwent analyses. Mean FM was 489.9 ± 439.5 g and 448.5 ± 337.5 g, lean mass was 2276.0 ± 1021.4 g and 2256.0 ± 1026.0 g, fat-free mass was 2356.3 ± 1055.1 g and 2389.5 ± 1081.1 g and BMC was 80.3 ± 39.5 g and 79.9 ± 42.4 g by DXA and chemical analysis, respectively. The two methods were highly correlated (0.84 to 0.99) and not significantly different, although LOA were large. DXA has the potential to be used to assess body composition of echidnas although further work is required to improve accuracy of measurement.","PeriodicalId":55420,"journal":{"name":"Australian Journal of Zoology","volume":"6 1","pages":"73 - 81"},"PeriodicalIF":0.8,"publicationDate":"2020-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81089253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
