Summary

Bats constitute one of the most diverse and ecologically pivotal groups of mammals, occupying a broad array of habitats from tropical forests to temperate woodlands and urban landscapes. As nocturnal insectivores, frugivores or nectarivores, they fulfil essential ecosystem services including pest regulation, pollination and seed dispersal. Their reliance on roost sites ranging from cave systems and tree hollows to anthropogenic structures renders them vulnerable to habitat loss, disturbance and climate-driven shifts in resource availability. Hibernation and torpor enable energy conservation during periods of cold or food scarcity, yet also expose bats to emerging diseases such as white-nose syndrome. Conservation strategies must therefore integrate protection of critical roosts, mitigation of collision mortality at wind-energy installations, management of disease risk and maintenance of landscape connectivity. Advances in acoustic monitoring, citizen science and habitat modelling underpin adaptive management, while public engagement and policy incentives galvanise support for bat-friendly practices in agriculture, forestry and urban planning. A transdisciplinary approach is crucial to safeguard bat populations and the services they deliver under accelerating global change.

Bat Ecology and Conservation Strategies publication trend

The graph below shows the total number of articles in bat ecology and conservation strategies across all publications each year (not limited to Nature Index journals).

Technical terms

Echolocation: The emission and reception of ultrasonic calls by bats to locate and identify prey and navigate in darkness.

Torpor: A reversible state of reduced metabolic rate and body temperature used by bats to conserve energy during unfavourable conditions.

Hibernacula: Specific sites, such as caves or mines, where bats hibernate in clusters to survive winter food scarcity.

Body Condition Index (BCI): A quantitative measure of an animal’s mass relative to its size, indicating health and energy reserves.

Passive acoustic monitoring: The non-invasive recording of bat calls to assess presence, activity levels and species composition over time.

About these summaries

This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
