In the current study, display flights of male Brown Songlarks (Cincloramphus cruralis Vigors and Horsfield 1827) before and after the application of fenitrothion (O,O-dimethyl-O-[3-methyl-4-nitrophenyl]-phosphorothioate) during locust spray operations around Conargo, south western New South Wales, were monitored incidentally for number, duration and the presence of song during flight. The duration of display flights undertaken by male C. cruralis showed a statistically significant increase after exposure to fenitrothion (t0.05, 398 = 1.97; p = 0.0085, analysed using log10 transformed flight duration data), despite the mean number of flights undertaken decreasing from 5.7 pre-spray to 4.7 post-spray during 10 min survey periods. The proportion of display flights in which the male was calling, however, did not differ between pesticide-exposed and unexposed male C. cruralis (χ2(0.05, 1) = 0.323; p = 0.570). To better understand the impacts of pesticide exposure on C. cruralis behaviour and ecology, the observations presented here require further study and validation with the addition of other variables such as territory mapping, assessment of reproductive success and the quantification of enzymatic biomarkers indicative of exposure to organophosphorous insecticides, undertaken concomitantly.","PeriodicalId":430003,"journal":{"name":"The Australian zoologist","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136293041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The collection of such data is the only way of quantifying the number of birds a habitat can support, how many fledglings it can produce, and the avian diversity that can exist in the habitat. Without these quantitative and qualitative measures, the significance of particular habitats for avian conservation is difficult to assess. We have accumulated comprehensive data on a breeding bird community on a 10 ha site for eight seasons, which has enabled us to condense the many aspects of breeding into an ‘average’ breeding season. The breeding community consisted of 44 species, which used all of the site for nesting. Some species bred each season, while others bred as infrequently as once in the eight seasons. Nesting occurred between the beginning of August and the end of January, different species showed markedly different starting and finishing times, and there were different temporal patterns of breeding within the breeding periods of the different species. The number of pairs that bred on the site varied each season, a pattern that we have previously shown to be related to the value of the Southern Oscillation Index before the start of the season. Nest success rates varied considerably between species, but the overall success rate on the site was approximately 50%. We estimate that the spotted gum forest habitat on the south-east coast of Australia (1200 km2) produces approximately 1.5 million fledglings each season.","PeriodicalId":430003,"journal":{"name":"The Australian zoologist","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133227072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since 1980 ecologists have used the discrepancies in dingo densities across the DBF to study the ecological role of Australia’s largest terrestrial predator.\u0000 We used drone imagery, ground based shrub and tree counts, and camera trap footage to test our hypothesis that there are alternate states in plant, bird and mammal assemblages on either side of the DBF. We found that shrubs and trees were twice as dense where dingoes were rare, and 28 % of shrub and tree species, 78 % of mammal species, and 14 % of bird species recorded were significantly more likely to occur on one side of the DBF than the other.\u0000 We provide the first comprehensive snapshot of how flora and fauna assemblages differ across the DBF. This study adds to literature demonstrating that the removal of the dingo has led to profound shifts in the shrub, mammal and bird assemblages in arid Australia. Any expansion of dingo control in arid Australia must be considered against the far-reaching consequences for ecosystem assembly associated with the removal of a top predator.","PeriodicalId":430003,"journal":{"name":"The Australian zoologist","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122997315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cairns","doi":"10.7882/AZ.2021.004","DOIUrl":"https://doi.org/10.7882/AZ.2021.004","url":null,"abstract":"\u0000 Controversy about the nomenclature and taxonomy of dingoes has sparked interest in their complex identity. At the root of taxonomy debates are differences in the species concepts employed, differing opinions about the domestication status of dingoes (and their ancestors) and a simplistic handling of the complex evolutionary relationship between wolves, dingoes and domestic dogs. I explore the relationship of dingoes to village dogs, modern breed dogs and wolves using genome-wide SNP data and discuss the implications of these findings to the ongoing debate about dingo identity and nomenclature. Importantly, despite controversy about what to call dingoes and whether they are a full species, these animals represent an important, distinct and unique evolutionary unit worthy of high conservation priority, as a native species. There is growing concern about the spread of domestic dog genes into dingo populations, particularly in southeastern Australia, and the impact this has on conservation goals. However, the discovery of biogeographic subdivision within dingoes raises questions about the accuracy of the current methods used for estimating dog vs dingo ancestry. I caution scientists and wildlife managers to carefully consider the limitations of current ancestry estimate methods when assessing DNA test results. Future work using genome-wide DNA technology to improve dingo ancestry estimates will be fundamental to ongoing debate about what dingoes are, how to identify dingoes and how to conserve them.","PeriodicalId":430003,"journal":{"name":"The Australian zoologist","volume":"10 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123098722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
