Conflicts and alliances in insect families

Article Abstract:

Advances in effectiveness of genetic markers used to resolve family structure in insect societies have brought studies that have tested predictions and they are discussed in this short review article. Results suggest that workers often control sex allocation, which supports the idea that kin selection is a major evolutionary force. That brings new conflicts to light. Studies now address selection for selfishness at the individual level with costs of social disruption at the colony level. Social insects are examples of how some individuals may be selected to not reproduce, only helping others reproduce.

Genetic structure of Siberian lemmings (Lemmus sibiricus) in a continuous habitat: large patches rather than isolation by distance

Article Abstract:

Large patches rather than isolation by distance has been seen in study of genetic structure of Siberian lemmings in a continuous habitat. Populations that had not yet reached an equilibrium structure after a major mixing event were studied.
