From earthquakes to island area: multi‐scale effects upon local diversity

Liam Trethowan, Fabian Brambach, Rodrigo Cámara‐Leret, Yves Laumonier et autres

Tropical forests occupy small coral atolls to the vast Amazon basin. They occur across bioregions with different geological and climatic history. Differences in area and bioregional history shape species immigration, extinction and diversification. How this effects local diversity is unclear. The Indonesian …

PipersectionMuldera(Piperaceae) of the Malay Peninsula: variation and species limits

Rani Asmarayani

Abstract Species limits in Piper spp. have been unstable, with specimens often assigned to different species by different botanists. Using a strongly supported clade of Asian Piper section Muldera, I investigated species boundaries in the eight Malay Peninsula species using morphological, anatomical …
