Biomineralization by photosynthetic organisms: evidence of coevolution of the organisms and their environment?

16 Dec 2009 Biomineralization is widespread among photosynthetic organisms in the ocean, in inland waters and on land. The most quantitatively important biogeochemical role of land plants today in biomineralization is silica deposition in vascular plants, ... Read more...

New metacentric population of the house mouse (Mus musculus domesticus) found in Valchiavenna, Northern Italy.

25 Oct 2009 Although the standard karyotype of the western house mouse (Mus musculus domesticus) consists entirely of telocentric chromosomes, there are over 100 populations across western Europe and North Africa characterized by different sets of metacentrics ... Read more...

Cooperative social clusters are not destroyed by dispersal in a ciliate.

12 Oct 2009 BACKGROUND: The evolution of social cooperation is favored by aggregative behavior to facilitate stable social structure and proximity among kin. High dispersal rates reduce group stability and kin cohesion, so it is generally assumed that there is ... Read more...
