Inbreeding and extinction in a butterfly metapopulation
It has been proposed that inbreeding contributes to the decline and eventual extinction of small and isolated populations,. There is ample evidence of fitness reduction due to inbreeding (inbreedingExpand

What do we need to know about speciation?
Speciation has been a major focus of evolutionary biology research in recent years, with many important advances. However, some of the traditional organising principles of the subject area no longerExpand

Variation in migration propensity among individuals maintained by landscape structure
Metapopulation dynamics lead to predictable patterns of habitat occupancy, population density and trophic structure in relation to landscape features such as habitat patch size and isolation.Expand

Cold tolerance and cold‐induced modulation of gene expression in two Drosophila virilis group species with different distributions
The importance of high and low temperature tolerance in adaptation to changing environmental conditions has evoked new interest in modulations in gene expression and metabolism linked with stressExpand

Genetic Divergence Among Host-Specific Cryptic Species in Cotesia melitaearum Aggregate (Hymenoptera: Braconidae), Parasitoids of Checkerspot Butterflies
Abstract We used mitochondrial DNA sequence data and 12 microsatellite loci to examine the genetic structure of Cotesia melitaearum (Wilkinson) (Hymenoptera: Braconidae), a parasitoid wasp rearedExpand

Seasonal gene expression kinetics between diapause phases in Drosophila virilis group species and overwintering differences between diapausing and non-diapausing females
Most northern insect species experience a period of developmental arrest, diapause, which enables them to survive over the winter and postpone reproduction until favorable conditions. We studied theExpand

Adaptation to a seasonally varying environment: a strong latitudinal cline in reproductive diapause combined with high gene flow in Drosophila montana
Adaptation to seasonal changes in the northern hemisphere includes an ability to predict the forthcoming cold season from gradual changes in environmental cues early enough to prepare for the harshExpand

Metapopulation genetic structure of two coexisting parasitoids of the Glanville fritillary butterfly
We investigated the metapopulation genetic structure of two specialist parasitoids, Cotesia melitaearum and Hyposoter horticola, attacking the Glanville fritillary butterfly (Melitaea cinxia) in theExpand

Molecular phylogeny of Cotesia Cameron, 1891 (Insecta: Hymenoptera: Braconidae: Microgastrinae) parasitoids associated with Melitaeini butterflies (Insecta: Lepidoptera: Nymphalidae: Melitaeini).
Phylogenetic relationships among Cotesia Cameron (Braconidae) species parasitising Melitaeini butterflies were examined using DNA sequence data (mitochondrial cytochrome oxidase subunit I and NADH1Expand

Changes in gene expression linked with adult reproductive diapause in a northern malt fly species: a candidate gene microarray study
BackgroundInsect diapause is an important biological process which involves many life-history parameters important for survival and reproductive fitness at both individual and population level.Expand
