Averting biodiversity collapse in tropical forest protected areas
These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines. Expand
Nouragues: dynamics and plant-animal interactions in a neotropical rainforest.
This work presents a meta-analysis of the distribution and life histories of amphibians and reptiles of the Arataye river and their space-time organization, as well as the dispersal and recruitment of Cyclanthaceae and Philodendron (Araceae) understorey root-climbing vines, which reveals a complex web of interactions between these animals and their environment.

Above-ground biomass and productivity in a rain forest of eastern South America
The increase in above-ground biomass for both trees and lianas is consistent with the hypothesis of a shift in the functioning of Amazonian rain forests driven by environmental changes, although alternative hypotheses such as a recovery from past disturbances cannot be ruled out at the site, as suggested by the observed decrease in stem density.

Seed-dispersal of Vouacapoua americana (Caesalpiniaceae) by caviomorph rodents in French Guiana
The disinterest of caviomorph rodents in germinated seeds, because of rapid exhaustion of endosperm reserves, prevents feeding from hoarded Vouacapoua during the long dry season when resources are scarce. Expand
Causes and Consequences of a Tropical Forest Gold Rush in the Guiana Shield, South America
Abstract Statistical and spatial analyses of both historical time series and remotely sensed data show a link between the spatial distribution and growth of gold production across the Guiana ShieldExpand
Seed removal and seed fate in Gustavia superba (Lecythidaceae)
The fate of the large seeds of Gustavia superba, an understory tree, was analyzed on Barro Colorado Island, Panama, and suggests that predator-disperser satiation occurred, maybe due to greater G. superba seed availability and other alternative food supply, allowing more G.superba seedling survival at the Gustavia-rich area. Expand
Seed mass, seedling size and neotropical tree seedling establishment
The results demonstrate that seed size influences performance within and among species in part because of indirect effects of initial seedling size and suggest that traits tightly correlated with seed mass at the species level, such as specific leaf area, leaf longevity and photosynthetic capacity, may also contribute to interspecific performance differences.

Bushmeat Hunting Alters Recruitment of Large‐seeded Plant Species in Central Africa
In the afrotropical context of a lack of data on plant‐animal ecological relationships, seed length appears to be a good predictor of the strength of the deficit of plant recruitment due to large mammal extirpation because of hunting. Expand
Phylogenetic density dependence and environmental filtering predict seedling mortality in a tropical forest.
This work assessed the effects on seedling mortality of functional similarity, phylogenetic relatedness and stem density of neighbouring seedlings and adults in a species-rich tropical forest to affirm the prominence of NDD in structuring species- rich communities. Expand
