摘要

了解动物的行为模式可以帮助人们了解种群和群落是如何适应更广泛的环境变化的。北巨蜥(Dasyurus hallucatus)是一种濒危有袋类食肉动物,传统上被归类为夜行性动物。然而,有证据表明,这种简单的分类法掩盖了动物活动模式的复杂性。我们的研究利用带有时间戳的相机陷阱图像和精细的加速度计数据,探索了澳大利亚北部地区北狐的昼夜活动模式。与传统的夜间活动分类相反,我们发现在本研究考察的五个种群中,有四个种群的北冠猴采用了双峰活动模式。活动和加速度计数据显示,每晚有两个活动高峰,午夜前后会出现明显的平静期,这种模式与其他有袋类掠食者的活动模式类似。我们没有发现季节或月相对时间活动有一致的影响。相反,它的时间活动模式可能主要受这里没有考虑到的因素的影响,如猎物的可获得性、气候、捕食者的回避或与消化有关的能量消耗。我们建议将这些因素纳入进一步的研究,以增进我们对北巨蜥行为的了解。

Midnight siesta: Bimodal temporal activity observed in an endangered marsupial predator

Midnight siesta: Bimodal temporal activity observed in an endangered marsupial predator

Understanding animal behavioural patterns can provide insight into how populations and communities are adapting to broader environmental shifts. The northern quoll (Dasyurus hallucatus), an endangered marsupial predator, has traditionally been classified as nocturnal. However, evidence is emerging that such simple classifications belie the complexity of animal activity patterns. Using time-stamped camera trap imagery and fine-scale accelerometer data, our study explores the diel activity patterns of northern quolls across their range in northern Australia. Contrary to the conventional nocturnal classification, we found that the northern quoll used bimodal activity patterns in four of the five populations examined in this study. Activity and accelerometer data showed two nightly movement peaks, with a distinctive lull around midnight, a pattern similar to one displayed by other marsupial predators. We found no consistent effect of season or lunar phase on temporal activity. Instead, its possible temporal activity patterns are primarily influenced by factors not accounted for here, such as prey availability, climate, predator avoidance, or energy expenditure related to digestion. We suggest further research incorporating these factors will improve our understanding of northern quoll behaviour.

期刊介绍: Austral Ecology is the premier journal for basic and applied ecology in the Southern Hemisphere. As the official Journal of The Ecological Society of Australia (ESA), Austral Ecology addresses the commonality between ecosystems in Australia and many parts of southern Africa, South America, New Zealand and Oceania. For example many species in the unique biotas of these regions share common Gondwana ancestors. ESA''s aim is to publish innovative research to encourage the sharing of information and experiences that enrich the understanding of the ecology of the Southern Hemisphere. Austral Ecology involves an editorial board with representatives from Australia, South Africa, New Zealand, Brazil and Argentina. These representatives provide expert opinions, access to qualified reviewers and act as a focus for attracting a wide range of contributions from countries across the region. Austral Ecology publishes original papers describing experimental, observational or theoretical studies on terrestrial, marine or freshwater systems, which are considered without taxonomic bias. Special thematic issues are published regularly, including symposia on the ecology of estuaries and soft sediment habitats, freshwater systems and coral reef fish.
