TL;DR: The effect of inbreeding on local extinction in a large metapopulation of the Glanville fritillary butterfly is studied and it is found that extinction risk increased significantly with decreasing heterozygosity, an indication of inmarriage.

TL;DR: A distillation of questions about the mechanisms of speciation, the genetic basis of speciating and the relationship between speciation and diversity are presented.

TL;DR: It is demonstrated with an evolutionary metapopulation model parameterised for the Glanville fritillary that increasing spatial variation in landscape structure increases variance in mobility among individuals in a metapoulation, supporting the general notion that complex landscape structure maintains lifehistory variation.

TL;DR: This work studies adaptation to seasonal changes in Drosophila montana by defining the photoperiodic conditions leading to adult reproductive diapause along a latitudinal cline in Finland and measuring genetic differentiation and the amount of gene flow between the sampling sites with microsatellites to show that local adaptation may occur even in the presence of high gene flow.

TL;DR: These analyses uncover longitudinal population structure, provide evidence for continent-wide selective sweeps, identify candidate genes for local climate adaptation, and document clines in chromosomal inversion and transposable element frequencies in European Drosophila melanogaster.
