Lessons from an eradication under multiple constraints of an island rat population of record density

open access: yesConservation Biology, EarlyView.
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

A link between increased temperature and avian body condition in a logged tropical forest

open access: yesConservation Biology, EarlyView.
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Home ranges, feeding sites, and daily movement behavior of the highly threatened Livingstone's fruit bat revealed through GPS tracking

open access: yesConservation Science and Practice, EarlyView.
Livingstone's fruit bat GPS tracks during day‐ and nighttime on Anjouan, Comoros, identifying likely feeding sites. Abstract The highly threatened Livingstone's fruit bat, Pteropus livingstonii, is endemic to only two islands of the Union of the Comoros, a country with some of the highest deforestation rates worldwide.

Distance of movement in three threatened butterfly species

open access: yesEcological Entomology, EarlyView.
Multi‐year mark–recapture analysis using net displacement and Cormack–Jolly–Seber models shows similar daily detectability (0.17–0.22) among species, supporting robust interspecific comparisons. Dispersal kernels differ: lognormal best for Euphydryas aurinia and Parnassius apollo, exponential for Phengaris arion; P.

Strong diel variation in the activity of insect taxa sampled by Malaise traps

open access: yesEcological Entomology, EarlyView.
Malaise traps sampled different communities during mornings (06:00–12:00), afternoons (12:00–16:00), evenings (18:00–22:00), and nights (22:00–06:00), highlighting the difference in diel rhythm between taxa. The highest diversity and abundance of insects were found during afternoons, the lowest diversity during night, and the lowest abundance during ...
