Multifaceted Assessment of Amazonian Tree Diversity Reveals Pervasive Impacts of Human Modification

Global Change Biology, Volume 31, Issue 11, November 2025.
Amazonian forests impacted by humans have a reduced and different group of tree species than those forests that have never been impacted. The trees present in forests impacted by humans also have different evolutionary histories and functional characteristics.

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

Journal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still

Surviving in a Warming and Fragmented World: Long‐Term Population Dynamics of the Lizard Gonatodes humeralis

Austral Ecology, Volume 50, Issue 10, October 2025.
ABSTRACT Climate change presents significant challenges to species survival; however, the long‐term effects on tropical lizard populations remain poorly understood. Previous studies have predicted contrasting outcomes, with some forecasting a high risk of extinction due to rising temperatures, while others suggest greater resilience in tropical ...

DAMAGES CAUSED BY FIRE ON THE NATURAL VEGETATION IN A PRIMARY FOREST IN ACRE STATE, BRAZILIAN AMAZON

Ciência Florestal, 2013
http://dx.doi.org/10.5902/198050989276The emission of CO2 is an important cause of the greenhouse effect and the Amazonian burns contribute to it. Because of the high moisture retained, the primary Amazon forest is considered immune to fire, however ...

Migration Patterns of Epiphyllous Bryophyte Metapopulations in Amazonian Fragmented Landscape Inferred From Census and Genomic Data

Biotropica, Volume 57, Issue 5, September 2025.
We examined the long‐term genetic consequences of habitat fragmentation on two epiphyllous bryophyte species in experimentally fragmented Amazonian forests. Using genotyping and demographic data, we found species‐specific responses and metapopulation dynamics in relation to their mating system.
