Environmental gradients mediate dispersal evolution during biological invasions

The paper models how environmental gradients affect dispersal evolution during biological invasions, finding that gradients can reduce dispersal and increase invasion predictability.

Immigration delays but does not prevent adaptation following environmental change: experimental evidence

This study shows that immigration of naive individuals delays but does not prevent adaptation in populations facing environmental change, using red flour beetles as a model.

Adaptation at the edge: Patterns of local adaptation and genetic variation during a contemporary range expansion

The paper examines how genetic variation and adaptation differ between core and expanding edge populations during a range expansion, finding that core populations are better adapted to local environments than edge populations.

Population demographic history and evolutionary rescue: influence of a bottleneck event

This study shows that populations without a bottleneck event are more likely to survive and adapt to environmental change than those with intermediate or strong bottlenecks.

How density dependence, genetic erosion, and the extinction vortex impact evolutionary rescue

This study shows that density dependence and genetic erosion reduce evolutionary rescue chances and increase extinction risk in populations facing environmental change.

Rapid and transient evolution of local adaptation to seasonal host fruits in an invasive pest fly

This study shows that local adaptation, not phenotypic plasticity, dominates in Drosophila suzukii populations adapting to changing host fruits over generations.

How do invasion syndromes evolve? An experimental evolution approach using the ladybird Harmonia axyridis

This study uses artificial selection on H. axyridis to investigate how invasion syndromes evolve, finding that selecting on age at first reproduction leads to more widespread phenotypic changes than selecting on body mass.

The response to drought-stressed host plants varies among herbivorous mite populations from a climate gradient

This study examines how drought stress affects life history traits of Tetranychus urticae mites from different climates, finding that origin climate influences their response to drought.

Increasing temporal variance leads to stable species range limits

The paper shows that temporal environmental variation affects species range limits by altering population expansion or extinction based on temporal autocorrelation and spatial gradients.

Adaptation and correlated fitness responses over two time scales in Drosophila suzukii populations evolving in different environments

This study tracks fitness changes in Drosophila suzukii populations across multiple generations and environments, revealing how adaptation dynamics differ over time.

Hybridization and range expansion in tamarisk beetles (Diorhabda spp.) introduced to North America for classical biological control

This study examines the genomic consequences of hybridization and range expansion in tamarisk beetles introduced to North America for biocontrol, finding increased genetic diversity in hybridized populations.

Parsing propagule pressure: Number, not size, of introductions drives colonization success in a novel environment

This study shows that the number, not the size, of introductions drives colonization success in a novel environment, using flour beetles and simulations.
