Introduced species infiltrate recent stages of succession after glacial retreat on sub-Antarctic South Georgia.
Biological invasions are one of the main drivers of global biodiversity decline. At the same time, glacial retreat induced by climate warming is occurring at an alarming rate across the globe, threatening unique taxa and ecosystems. However, we know little about how introduced species contribute to the dynamics of colonisation... -

Mapping density, diversity and species-richness of the Amazon tree flora.
Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness. Using only location, stratified by forest type, as predictor, our spatial model, to the best of our knowledge, provides the most... -

An enlarged circumscription of Bifrenaria (Orchidaceae: Maxillariiinae).
A revised delimitation of Bifrenaria broadens the genus to include the previously accepted genera Guanchezia, Horvatia, Hylaeorchis, Rudolfiella, Scuticaria, and Teuscheria. These genera as currently circumscribed are changed to sections, and their respective species transferred or combined along with newly synonymised species. Bifrenaria sect. Stenocoryne and B. sect.

Bien que la production d'igname augmente en Guinée, à long terme, la...
