Bee dispersal ability may influence conservation measures

The abilities of various bee species to disperse influences the pattern of their population's genetic structure, which, in turn, can constrain how they respond to environmental change, as reported by an international team ...

It's all in the genes—including the tracking device

Parentage-based tagging (PBT) is an emerging genetic-based fish tagging method that involves genotyping hatchery broodstock. PBT is a passive non-invasive approach to stock identification because the parents, not the offspring, ...

The peculiar life history of Middle American Stenamma ants

Stenamma is a cryptic "leaf-litter" ant genus that occurs in moderately humid to wet forest habitats throughout the Holarctic region, Central America, and part of northwestern South America (Colombia and Ecuador). The genus ...

How to create less selfish societies?

(GPEARI, Portugal) -- Cooperation, despite being now considered the third force of evolution, just behind mutation and natural selection, is difficult to explain in the context of an evolutionary process based on competition ...
