Anthropogenic and natural factors are associated with bird dawn chorus onset in subtropical East Asia

Ibis, EarlyView.
Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...

Bird community seasonality and long‐term changes in migrant birds across a large savanna protected area in South Africa

Ibis, EarlyView.
Migratory bird species fascinate humanity but also contribute significantly to the ecosystems they visit in various ways (e.g. food web structures) and can thus be considered good environmental indicators. Although protected areas (PAs) should play an important role in the conservation of migratory species, this is not always achieved; for example ...

Synthesizing knowledge gaps to prioritize conservation actions for owls and nightjars in Africa

Ibis, EarlyView.
Owls (Strigiformes) and nightjars (Caprimulgiformes) play important ecological roles but remain among the least studied avian groups, with critical knowledge gaps potentially limiting effective conservation planning. We conducted a systematic literature review to quantify temporal, spatial, taxonomic and thematic patterns of research on African owls ...

Protection status and environmental gradients shape butterfly assemblages in an East African tropical ecosystem

Insect Conservation and Diversity, EarlyView.
Observed butterfly richness was highest in moderately protected areas. During the dry season, vegetation productivity increased butterfly richness while human population density reduced it. Moderately protected areas supported high butterfly abundance and a high proportion of host‐specialist species.

Fire‐driven forest degradation enhances termite activity and accelerates litter decomposition in the Amazonia rainforest

Insect Conservation and Diversity, EarlyView.
Forest degradation increased termite‐mediated litter decomposition, whereas no such effect was detected in undisturbed forests. Reduced ant predation and altered forest conditions were associated with higher termite abundance and faster litter decomposition.
