Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River. [PDF]

Conserv Biol
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Tropical Land-Use Change Disrupts Zeta-Diversity Across Taxa. [PDF]

Glob Chang Biol
We studied birds, dung beetles, and orchids across natural and human‐transformed habitats in the Colombian Andes to understand how land‐use change affects biodiversity. We found that deforestation simplifies ecological communities and reduces both rare and widespread species, especially orchids.
