Rare long-distance dispersal events help maintain genetic structure of mangroves

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

A study combining genetic analysis and oceanographic simulations showed that a species of mangrove rarely disperses very far, so that North and South Brazil have two distinct populations. The results can help prioritize conservation units and understand global patterns in mangrove forest formation.

More work needed to unlock mysteries of Asia’s bees

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

Although the collapse of hives of European honey bees (Apis mellifera) has gained worldwide attention in recent years, there are massive gaps in knowledge of other bee species, particularly in the Asian region, which contains over half the world’s human population and where food security (in which bees play a key role) remains a major challenge.
