Frequency-dependent selection predicts patterns of radiations and biodiversity
Most empirical studies support a decline in speciation rates through time, although evidence for constant speciation rates also exists. Declining rates have been explained by invoking niche-filling…

Computer simulations on the sympatric speciation modes for the Midas cichlid species complex
Cichlid fishes are one of the best model system for the study of evolution of the species. Inspired by them, in this paper we simulated the splitting of a single species into two separate ones via …

Plants at risk from climate change
The popular garden flower Cyclamen grows natively in the Mediterranean. Climate change could make the region unsuitable for 18/21 species in 50 years time. Ant-dispersed Cyclamen can’t hope to mi…
