1. Ecology and evolution of butterfly host plant range
Sammanfattning : .... LÄS MER
2. Effect of climate and land use on niche utilization and distribution of nettle-feeding butterflies
Sammanfattning : Anthropogenic changes in climate and land use are causing a dramatic erosion of biodiversity. To understand this erosion, and predict future transformations of biodiversity, we need to understand better species’ response to these changes at different spatial and temporal scales. LÄS MER
3. Evolution of host repertoires and the diversification of butterflies
Sammanfattning : All herbivorous insects are specialized to some extent to their host plants, but the level of specialization varies greatly. Insect-plant coevolution is often invoked to explain the large diversity of herbivorous insects, but the role of specialization during diversification is still controversial. LÄS MER
4. Evolutionary and mechanistic aspects of insect host plant preference
Sammanfattning : Plant feeding insects comprise about 25% of all animal species on earth and play an important role in all ecosystems. Although we understand that their association with plants is a key-factor driving the diversification in this group, we still have large gaps in our knowledge of the underlying processes of this relationship.

5. The plasticity and geography of host use and the diversification of butterflies
Sammanfattning : Our world is changing rapidly and factors like urbanisation, changed agricultural practices and climate change are causing losses in butterfly diversity. It is therefore of importance to understand the source of their diversity. LÄS MER
