The paper tests mating patterns in replicated secondary contact experiments and finds disassortative mating instead of expected assortative mating or reproductive isolation.

The paper examines genomic differentiation between marine and freshwater stickleback populations in Atlantic Canada, identifying regions consistently differentiated despite varying demographic histories.

This study introduces >12,000 threespine stickleback into nine lakes to test if environmental matching or intrinsic population traits predict introduction success, finding intrinsic traits are more important.

This study shows that freshwater copepods evolved tolerance to acidification and then lost it after pH recovery, demonstrating evolutionary rescue in natural populations.

This study shows nutrient enrichment reduces bacterioplankton taxonomic diversity but connectivity can restore functional diversity in highly stressed freshwater communities.

This study shows that glyphosate-based herbicide affects bacterial community diversity but not within-species genetic diversity, identifying gene targets of selection in freshwater bacterioplankton.

The paper identifies a premature stop codon in the gch2 gene in axanthic ball pythons, linking it to pterin-based pigmentation and establishing ball pythons as a vertebrate model for studying axanthism.

The paper shows that pre-exposure to stress increases community and genetic diversity resilience in bacterial communities under severe acidification.

The paper experimentally studies host-parasite dynamics in newly founded stickleback populations, finding destabilized infection rates and rapid eco-evolutionary responses.

The paper tracks seasonal allele frequency changes in stickleback populations to identify signs of parallel natural selection during environmental shifts.

The paper identifies a nonsense mutation in TFEC as the likely cause of the piebald phenotype in ball pythons using whole-genome sequencing and population genetics.

The paper investigates how genetic variation in wild mice affects fitness by linking genotype to phenotype and allele frequency changes through field and lab experiments.
