Afforestation of tropical savannas has mixed consequences for bird communities
Conservation Science and Practice, Volume 8, Issue 5, May 2026.Moving beyond the prevailing binary perception of savanna afforestation being either ‘good’ or ‘bad’ for native biodiversity, our data suggests that plantations on the rainfall extremes should be viewed as important supplementary habitats for biodiversity.

Assessing Conflict Potential Between Birds and Small‐Scale Fisheries in Lake Titicaca
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 4, April 2026.ABSTRACT Globally, fisheries bycatch constitutes a threat to aquatic birds. However, while the threat is global, the threat from bycatch in inland fisheries, and from artisanal or small‐scale fishing, is particularly understudied. Here, we present the first attempt to map the vulnerability of birds to fisheries bycatch, and the conflict potential ...

Ecology and Evolution, Volume 16, Issue 4, April 2026.This study employs DNA metabarcoding to analyze the diet composition of the critically endangered Chinese crested tern and the greater crested tern during their breeding season in Zhejiang. The terns primarily consume epipelagic schooling fish like anchovies and mackerel, with minimal overlap with commercial fisheries (< 5% commercial fish).

A view from above : changing seas, seabirds and food sources [PDF]
, 2009 In this review we summarize what is known about mechanisms by which climate change may be affecting the populations of seabirds around the UK. Breeding success and adult survival are the key factors affecting changes in seabird populations, and food ...

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle
Oikos, Volume 2026, Issue 4, April 2026.The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.
