Hybridization but minimal introgression: ecologically-based divergent selection maintains a steep hybrid zone in parapatric stickleback fish

The paper investigates a steep hybrid zone between lake and stream stickleback ecotypes, finding that divergent ecological selection maintains reproductive isolation despite recent habitat contact.

Among-population variation in the threespine stickleback ( Gasterosteus aculeatus ) liver metabolome: effects of ancestry and environment

This study examines metabolome variation in threespine stickleback across populations, showing both genetic and environmental influences on liver metabolites.

Disassortative mating in replicated secondary contact experiments in nature

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

Behavior and Physiology Outpace Form When Linking Traits to Ecological Responses Within Populations: A Meta-Analysis

This study meta-analyzes over a thousand effect sizes to show that trait variability within populations influences ecological responses more strongly for physiology and behavior than morphology.

Intrinsic fitness differences outweigh environmental matching in shaping introduction outcomes in nature

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.

Lake size shapes the relationship between body mass and gut microbiota in threespine stickleback (Gasterosteus aculeatus)

This study shows that lake size influences how body mass relates to gut microbiota diversity in threespine stickleback fish, with intermediate-sized lakes showing the most diverse microbiota.

Fish Show Genetic Evolutionary Responses to River Regulation

The paper investigates genetic evolutionary responses of fish to river regulation by analyzing genetic divergence and gene function in three-spined stickleback populations.

GTP cyclohydrolase II (gch2) and axanthism in ball pythons: a new vertebrate model for pterin-based pigmentation

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.

Destabilized host-parasite dynamics in newly founded populations

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

Using seasonal genomic changes to understand historical adaptation: parallel selection on stickleback in highly-variable estuaries

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

A nonsense mutation in TFEC is the likely cause of the recessive piebald phenotype in ball pythons (Python regius)

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.

Six percent loss of genetic variation in wild populations since the industrial revolution

The paper estimates a 6% loss of genetic variation in wild populations since the industrial revolution, with island species experiencing an 18% average decline.

Thirty-five experimental fisheries reveal the mechanisms of selection

The paper uses 35 experimental fisheries to study how environmental and demographic factors influence fishing-induced selection on trout populations.
