Background: A central tenet of the evolutionary theory of communities is that competition impacts evolutionary processes such as local adaptation. Species in a community exert a selection pressure on other species and may drive them to extinction. We know, however, very little about the influence of unsuccessful or ghost species on the evolutionary...

Dispersing individuals are expected to encounter costs during transfer and in the novel environment, and may also have experienced stress in their natal patch. Given this, a non-random subset of the population should engage in dispersal and show divergent stress-related responses. This includes physiological shifts as expressed in the metabolome, w...
La forêt méditerranéenne est en première ligne face au changement climatique. Les dépérissements de nombreuses espèces (chênes, pins, sapins) y ont fortement augmenté au cours des 30 dernières années. La combinaison de sécheresses répétées avec des incendies plus fréquents et plus violents menace la survie même de certains écosystèmes. En 2017, mêm...
1. Interactions between emerging contaminants and other drivers of community structure and function are poorly known. We used laboratory microcosms to investigate the single and combined effects of grazing and triclosan toxicity on the structure and function of stream periphyton. 2. Grazing alone strongly reduced algal biomass, but also reduced oxi...
Large ungulates as primary consumers consume variable proportions of herbaceous and woody plants. Recent climate changes modify the herbaceous/woody plant balance. To test their differential effects on ungulate species abundance, we compared large ungulate feeding strategies with climate change patterns, taking the game preferences of local people ...

The degradation of the Andean cloud forest raises strong biological conservation issues and threatens the sustainability of a crucial water resource. The idea that nurse-based restoration can accelerate the recovery of these forests is underexplored, despite its promise as a restoration technique. Recent conceptual models predict that facilitation ...

El acelerado retroceso glaciar debido al actual calentamiento global conlleva nuevos desafíos para las comunidades vegetales altoandinas, especialmente durante el establecimiento de nuevos bofedales. Existe una confusión de ritmo entre el tiempo necesario para la colonización vegetal y el tiempo requerido para desarrollarse en ese tipo de ambiente,...
