Determinants of population persistence and abundance of terrestrial and arboreal vertebrates stranded in tropical forest land‐bridge islands

Conservation Biology, Volume 35, Issue 3, Page 870-883, June 2021., 2021
Abstract Megadams are among the key modern drivers of habitat and biodiversity loss in emerging economies. The Balbina Hydroelectric Dam of Central Brazilian Amazonia inundated 312,900 ha of primary forests and created approximately 3500 variable‐sized islands that still harbor vertebrate populations after nearly 3 decades after isolation. We estimated

Foraging behavioural traits of tropical insectivorous birds lead to dissimilar communities in contrasting forest habitats

Wildlife Biology, Volume 2019, Issue 1, Page 1-6, December 2019., 2019
Many deforested areas worldwide have been planted with Alnus spp. to protect watersheds and soils. However, the effects of these plantations on biodiversity are little known yet. Contrasting forest types may impose strong environmental filters to some behavioural traits, leading to dissimilar communities.
