The paper reared stickleback embryos from 27 lake populations in a lab to determine if trait-environment correlations reflect heritable evolution or plasticity, finding both heritable and plastic traits.

The paper investigates immune variation in threespine stickleback populations by analyzing fibrosis responses to parasites and environmental factors.

This study investigates reproductive adaptations in Astyanax mexicanus under nutrient limitation, finding cavefish maintain breeding ability under starvation due to increased maternal nutrient deposition and specific gene expression changes.

The paper measures scale cortisol levels in wild and lab-reared Astyanax mexicanus populations across different habitats, finding lower cortisol in some cave populations and higher levels in habitats with more environmental variability.
