Evidence from citizen science suggests foliage as a possible day roost for the hairy big-eyed bat (Chiroderma villosum)
Frugivorous bats in the subfamily Stenodermatinae are known to use foliage and cavities, such as tree hollows or caves, as roosting sites. Species with paler facial and dorsal markings are typically thought to prefer enclosed spaces, while those with more conspicuous markings often roost in more exposed locations. Among the genus Chiroderma, the hairy big-eyed bat (C. villosum) has the widest distribution and is the most studied ecologically, yet its roosting habits remain poorly understood. We present three observations of C. villosum using foliage as daytime roosting sites, with records from tropical rainforest areas in Belize, Brazil and Nicaragua. These findings challenge the assumption that C. villosum prefers enclosed spaces due to its less conspicuous pelage markings. The apparent scarcity of day roost reports for Chiroderma species may be due to their solitary roosting habits and the difficulty of spotting them in exposed shelters.
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.
