Biocrusts increase the resistance to warming-induced increases in topsoil P pools. [PDF]
Our findings provide novel insights on the responses of soil P pools to warming and rainfall reduction, and highlight the importance of biocrusts as modulators of these responses in dryland ecosystems. Our results suggest that the observed negative impacts of warming on dryland biocrust communities will decrease their capacity to buffer changes in ...

Our results demonstrate that soil nutrient‐based species selection is a prevalent driver of community assembly in tropical forests, a process mediated by key functional traits within the leaf and wood economics spectrum. Functional space size and its filling increase with soil nutrient concentration, whereas niche vacancy decreases.

ESTRATÉGIAS DE SOBREVIVÊNCIA DE ESPÉCIES ARBÓREAS EM AMBIENTES DEFICIENTES POR FÓSFORO NA AMAZÔNIA
As florestas secundárias (capoeiras) situadas no Nordeste do Estado do Pará, geralmente utilizadas pela agricultura itinerante, onde fases de regeneração da vegetação intercalam-se com fases de cultivo agrícola caracterizam-se pela baixa fertilidade dos ...
