Habitat use and diel activity of insectivorous bats across land‐cover types on an Afrotropical oceanic island

open access: yesConservation Science and Practice, EarlyView.
Using acoustic surveys, we investigated habitat use and diel activity patterns of insectivorous bats across the main land‐use types of the endemic‐rich Príncipe Island, in Central West Africa. We sampled bat activity at 48 sites spanning old‐growth forests, secondary regrowth forests, shaded cocoa plantations, and horticultural areas.

In an immunological twilight zone

open access: yesProceedings of the National Academy of Sciences, 1998
Early in their evolution, perhaps during their transition from Agnatha (jawless fish) to Gnathostomata (jawed animals), vertebrates committed as much as 1% of their protein-encoding genome to a new system of defense against parasites (1). Central to this anticipatory (adaptive) immune system (2) are three types of antigen receptor—immunoglobulin (Ig ...

Monitoring small‐scale fisheries through participatory, app‐based surveys in the tropical archipelago of São Tomé and Príncipe

open access: yesConservation Science and Practice, EarlyView.
Small Island Developing States have limited capacity to monitor Small Scale Fisheries, despite their high dependence on marine resources. Participatory monitoring of Small Scale Fisheries can fill data gaps while integrating resource users into fisheries management.

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 ...

Who prefers the dark? Daily activity of dung beetles from an Amazonian region

open access: yesEcological Entomology, EarlyView.
Daily activity patterns shape how dung beetle species coexist in Amazonian forests, revealing temporal niches that reduce competition and structure biodiversity. We compared species richness, abundance and assemblage composition of dung beetles sampled during day and night in a conserved terra‐firme forest in the Brazilian Amazon. Although richness and
