Global species structure, colonization-extinction dynamics and adaptive radiation of the cosmopolitan diatom clade Pinnularia borealis. University of Antwerp
Diatoms, unicellular algae with a siliceous cell wall, are ecologically widespread and highly diverse organisms. Until recently, it was believed that most diatom species are worldwide distributed. However, increasing evidence suggests the opposite to be true for many species. Phylogenetic data revealed that our model species Pinnularia borealis consists of morphologically similar forms, which in fact correspond to different species. With this ...
