Aim: Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated w...

Background and Aims Throughout the Cenozoic, Africa underwent several climatic and geological changes impacting the evolution of tropical rain forests (TRFs). African TRFs are thought to have extended from east to west in a ‘pan-African’ TRF, followed by several events of fragmentation during drier climate periods. During the Miocene, climate cooli...

RésuméLa tribu des Monodoreae (Annonaceae) est composée de 11 genres et 90 espèces des forêts tropicales humides d’Afrique. Tout les genres sont taxonomiquement bien résolus, à part les genres Uvariodendron et Uvariopsis qui manquent d’une révision taxonomique récente. Ici, nous avons utilisé une approche phylogénomique robuste pour estimer l’arbr...
Habitat loss affects the nature of biotic interactions in all ecosystems and at all levels of the food web. Nevertheless, little attention has been given to soil nematodes in tropical habitats despite their important role in ecosystem functioning worldwide. Here, we analyzed the influence of anthropogenic habitat disturbance on the absolute and rel...
To understand the feeding ecology of the unique burrow-utilizing fanged frog Limnonectes cintalubang in Borneo, we analysed its diet composition. Stomach contents were obtained by dissection of preserved specimens, and by forced regurgitation of living individuals from Ranchan Pool, Sarawak, Malaysia. Samples were compared with those of other speci...
This paper's results show that conflict variables have positive relationships with deforestation in Colombia; yet, they are not among the main variables explaining deforestation.

Understanding the evolutionary dynamics of genetic diversity is fundamental for species conservation in the face of climate change, particularly in hyper-diverse biomes. Species in a region may respond similarly to climate change, leading to comparable evolutionary dynamics, or individualistically, resulting in dissimilar patterns. The second-large...

Biological fixation of atmospheric nitrogen (N2) is the main pathway for introducing N into unmanaged ecosystems. While recent estimates suggest that free-living N fixation (FLNF) accounts for the majority of N fixed in mature tropical forests, the controls governing this process are not completely understood. The aim of this study was to quantify ...

Biotic homogenization, i.e., the increase in community similarity through time or space, is a commonly observed response following conversion of native ecosystems to agriculture, but our understanding of the ecological mechanisms underlying this process is limited for bacterial communities. Identifying mechanisms of bacterial community homogenizati...
