Species persistence following hybridization in nature requires the purging of introgressed alleles. Genomic monitoring of a tsunami-induced hybrid stickleback population in Japan reveals rapid genome-...

Rapid evolution may shape the success of invasive species. This study shows that the invasive plant species Erigeron canadensis repeatedly evolved increased competitive ability after introduction, and...

Synopsis. Invasive predators can influence prey through direct predation but also via nonconsumptive effects that alter behavior and physiology. Parental c

Abstract. The threespine stickleback (Gasterosteus aculeatus) is a key model in evolutionary genetics, particularly for studies of parallel evolution, yet

Predicting the distance between an individual's release point into a new environment and their subsequent location (‘displacement’) could be useful during biological ‘introduction’ events (e.g., i...

Abstract. Despite growing evidence of widespread genetic responses to anthropogenic activity, data shortfalls constrain genetic monitoring efforts and prec

Explore the Alaska Stickleback Project, focusing on threespine stickleback research investigating ecology and evolution in unique Alaskan environments.

Abstract. Hybridization between species can occur along repeated zones of contact, providing a natural laboratory for studying the interplay between migrat

Adaptation to different environments is thought to play a key role in speciation. However, speciation typically begins in allopatry, where reproduc...

Earth's c. 406 million herbarium specimens represent a largely untapped resource of genetic data that could transform our understanding of global plant populations. Advances in DNA sequencing have ma...
