The genomic and physiological basis of life history variation in a butterfly metapopulation

Klepsatel, Peter ; Flatt, Thomas

In: Molecular Ecology, 2011, vol. 20, no. 9, p. 1795-1798

Unravelling the mechanisms underlying variation in life history traits is of fundamental importance for our understanding of adaptation by natural selection. While progress has been made in mapping fitness-related phenotypes to genotypes, mainly in a handful of model organisms, functional genomic studies of life history adaptations are still in their infancy. In particular, despite a few...

Cytotype differences modulate eco-geographical differentiation in the widespread plant Centaurea stoebe

Hahn, Min A. ; Müller-Schärer, Heinz

In: Ecology, 2013, vol. 94, no. 5, p. 1005–1014

The evolution of optimal life history strategies is central for the fitness of organisms in a given environment. Besides divergent selection, other factors may determine regional patterns of differentiation and contribute to life history evolution. In a common-garden environment over three years, we examined life history differentiation across different eco-geographical regions and effects of a...
