Species functional traits affect regional and local dominance across western Amazonian forests

Journal of Ecology, Volume 114, Issue 1, January 2026.
Dominant tree species in western Amazonian forests show distinct functional trait combinations linked to habitat type: conservative traits in stressful habitats and greater plant size in less stressful environments. Local dominants are defined by resource conservation strategies and widespread dominants are defined by resource acquisition strategies. A

Habitat Amount Shapes Ant Diversity in the Central Amazon

Biotropica, Volume 58, Issue 1, January 2026.
Ant diversity in fragmented Amazonian forest landscapes is primarily driven by landscape‐scale habitat amount rather than fragment size, supporting the Habitat Amount Hypothesis (HAH) over Island Biogeography Theory (IBT). Consequently, conservation strategies should prioritize maintaining and restoring forest cover across human‐modified landscapes ...

Chemical Composition, Antioxidant, and Antibacterial Activities of Mezilaurus duckei (Lauraceae)

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Mezilaurus duckei, a Brazilian endemic tree species found exclusively in the Amazon Rainforest, is primarily exploited for timber in construction. Due to its endangered status, this study aimed to investigate the chemical profile and biological properties of the ethanolic extract and its phases derived from M. duckei leaves. Chemical profiling

Climate Change‐Induced Distribution Shifts of Keratin‐Feeding Beetle Omorgus (Omorgus) suberosus: Implications for Olive Ridley Sea Turtle Lepidochelys olivacea Conservation

Animal Conservation, Volume 28, Issue 6, Page 803-816, December 2025.
Our study projects significant climate change‐induced distribution shifts of a keratin‐feeding beetle Omorgus suberosus, with expansions into higher latitudes in Europe and North America and notable habitat losses in tropical regions by 2100. Ecological niche models predict a global habitat reduction of 9.5% under SSP2–4.5 and 20.8% under SSP5–8.5 ...
