Biotropica, Volume 58, Issue 2, March 2026.Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy‐derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over

TAXON, Volume 75, Issue 1, February 2026.Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

The frequency and importance of polyploidy in tropical rainforest tree radiations
New Phytologist, Volume 249, Issue 4, Page 2103-2114, February 2026.Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

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 ...
