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

open access: yesJournal 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

Wood density variation across an Andes‐to‐Amazon elevational gradient

open access: yesJournal of Ecology, Volume 113, Issue 9, Page 2370-2385, September 2025.
We study how wood density varies along a 3500‐m elevational gradient, spanning from the Andean tree line to the Amazon basin. Our results reveal that wood density decreases from low to mid‐elevations, then increases toward the tree line. These patterns underscore the influence of species composition, life forms such as tree ferns, and local ...

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

open access: yesBiotropica, 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.

Gene Flow and Vertical Stratification of Pollination in the Bat‐Pollinated Liana Marcgravia longifolia

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
This study investigates pollen dispersal, vertical stratification of gene flow, and spatial genetic structure in the bat‐pollinated liana Marcgravia longifolia in a western Amazonian forest. Flowers are produced from the forest floor to the canopy, allowing analysis of pollination across strata.

Stimulating reciprocity: How human–plant relations support Indigenous cultural revitalization and stewardship in the Ecuadorian Amazon

open access: yesPeople and Nature, Volume 7, Issue 5, Page 1151-1170, May 2025.
Abstract Human–plant relations shed light on forms of reciprocity in Indigenous territorial stewardship. This article shows how Cofán, Siona and Siekopai (also Secoya or Airo Pai in Peru) Indigenous Peoples in the western Amazon collect, cultivate and use yoco (Paullinia yoco) to promote communal conviviality, reclaim once‐threatened cultural practices

‘Sowing and harvesting water’: Revisiting forest restoration in the Peruvian Andes through a multi‐stakeholder analysis

open access: yesPeople and Nature, Volume 7, Issue 3, Page 631-652, March 2025.
Abstract Efforts to restore Peru's megadiverse Andean Forests are rapidly growing. While ecological determinants for restoration success are well known, knowledge on the socio‐economic and governance conditions that allow for the success of ecological restoration using native species is scarce.
