Immigration history controls diversification in experimental adaptive radiation
Article Abstract:
A study was conducted to show that the order and timing of immigration controls the extent of diversification by introducing the ancestral SM genotype and a derived WS genotype into spatially structured microcosms in different orders and at different intervals of time. The results demonstrate that immigration and diversification are tightly linked processes with small differences in immigration history greatly affecting the evolutionary emergence of diversity.

Evolution of species interactions in a biofilm community
Article Abstract:
A two-species community is used to show that the selection in a spatially structured environment has led to the evolution of an exploitative interaction. The results have shown that evolution of species in a spatially structured environment can stabilize the interactions between species, provoke marked changes in their symbiotic nature and affect community function.

Unity from conflict
Article Abstract:
Biologists are findings out the explanation to the way an evolutionary transition that involves a shift in the level at which selection operates, from individual entities to groups, could occur. Although the evolutionary emergence of groups is itself a profound event, such groups are typically short-lived.
