- Adaptive signatures in thermal performance of the temperate coral Astrangia poculata
Summary: Acute temperature stress assays reveal population-level differences in metabolic rate of the temperate coral Astrangia poculata, providing evidence of adaptation to the corals' natal thermal environments.
- Integration between swim speed and mouth size evolves repeatedly in Trinidadian guppies and aligns with suction-feeding fishes
Summary: Integration between swim speed and mouth size is absent in ancestral but present in derived populations of guppies, suggesting mechanisms for the evolution of integrated performance in fishes.
- High-frequency temperature variability mirrors fixed differences in thermal limits of the massive coral Porites lobata
Summary: Corals native to highly variable habitats demonstrate greater thermal tolerance than corals from less variable habitats after 36 days of acclimation to thermally stable or variable common garden treatments.
- Sticklebacks adapted to divergent osmotic environments show differences in plasticity for kidney morphology and candidate gene expression
Summary: Both plasticity and genetic variation in kidney morphology and candidate gene expression have likely facilitated adaptation to permanent low-salinity residency in threespine stickleback populations from the Baltic Sea.
- Thermal acclimation and subspecies-specific effects on heart and brain mitochondrial performance in a eurythermal teleost (Fundulus heteroclitus)
Summary: Heart and brain mitochondrial performance declines following acclimation to thermal extremes in killifish, which suggests that organismal performance at thermal extremes is, at least in part, constrained by mitochondrial performance.
- Geographic divergence and colour change in response to visual backgrounds and illumination intensity in bearded dragons
Highlighted Article: Background colour and illumination intensity both elicit colour change in bearded dragon lizards, which makes them more similar to local backgrounds.
