Genetic and phenotypic consequences of local transitions between sexual and parthenogenetic reproduction in the wild

This study examines the genetic and phenotypic effects of transitions between sexual and parthenogenetic reproduction in wild Megacrania batesii populations, finding reduced genetic diversity but no consistent fitness differences.

Contrasting patterns of single nucleotide polymorphisms and structural variations across multiple invasions

This study compares SNP and SV genetic diversity across invasive European starling populations, finding discrepancies in diversity patterns and evidence of balancing selection differences between SNP and SV classes.

In an arms race between host and parasite, a lungworm's ability to infect a toad is determined by host susceptibility, not parasite preference

The paper investigates how host susceptibility, not parasite preference, determines infection success in an invasive lungworm-toad system, showing range-edge toads have lower resistance due to weaker immune defenses.

Using historical museum samples to examine divergent and parallel evolution in the invasive starling

This study uses historical and contemporary samples of starlings to identify parallel and divergent evolutionary changes in invasive and native populations.

Concurrent invasions by European starlings (Sturnus vulgaris) suggest selection on shared genomic regions even after genetic bottlenecks

The paper compares whole-genome sequences of European Starlings from native and introduced populations to show that post-bottleneck expansion supports local adaptation through selection on shared genomic regions.

The gut bacteria of an invasive amphibian respond to the dual challenges of range-expansion and parasite attack

The study examines gut bacterial communities in cane toads across their invasive range and finds associations with host ecology, behavior, and parasite infection.

Signatures of selection in a recent invasion reveals adaptive divergence in a highly vagile invasive species

The paper analyzes genetic differentiation and selection signals in invasive starling populations in Australia to understand adaptation to environmental factors.

Immune and environment-driven gene expression during invasion: An eco-immunological application of RNA-Seq

The paper examines gene expression patterns in invasive cane toads, finding immune gene expression varies with invasion history and suggesting environmental adaptation.

Bottleneck revisited: increased adaptive variation despite reduced overall genetic diversity in a rapidly adapting invader

This study examines genetic diversity in invasive cane toads, finding reduced overall diversity but maintained diversity at ecologically relevant loci, suggesting natural selection plays a key role in adaptation.
