Irena has published two papers on the diversification of two genera of cold-adapted butterflies, Oeneis and Erebia, with her collaborators over the past several months. These papers show how climatic factors affected diversification and the spread of these butterflies through Europe over the last several millions of years. Together with our recent studies on thermoregulation and behaviour of Erebia butterflies, these results provide new information on the effects of environmental factors on cold-adapted butterflies at different levels from short-term behavioural responses to speciation and the evolution of climatic niches.
