The Impacts of Pregnancy on Cognition and Cell Proliferation in a Live-Bearing Fish (Poeciliopsis gracilis). [PDF]
Eur J NeurosciWe assessed the impact of pregnancy on cognition and cell proliferation in the live‐bearing fish Poeciliopsis gracilis. Pregnant females showed reduced spatial learning but unchanged reversal learning, alongside decreased cell proliferation in the olfactory bulb and ventral telencephalon, indicating pregnancy‐induced cognitive and neural changes in a ...

Diurnal Changes in Hypoxia Shape Predator-Prey Interaction in a Bird-Fish System
Frontiers in Ecology and Evolution, 2021 Animals often face changing environments, and behavioral flexibility allows them to rapidly and adaptively respond to abiotic factors that vary more or less regularly.

The complete mitochondrial genome of the Variable Platyfish Xiphophorus variatus
Mitochondrial DNA. Part B. Resources, 2021 We present the complete mitochondrial genome sequence of the Variable Platyfish, Xiphophorus variatus (Meek 1904) (Cyprinodontiformes: Poeciliidae). The genome consists of 16,624 bp which encodes 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal ...

New Genome Assemblies for Poeciliidae: A Foundation for Adaptation Studies. [PDF]
Genome Biol EvolAbstract Multiple lineages in the family Poeciliidae have independently adapted to hydrogen-sulfide-rich springs. The independent colonizations of such springs mean that there are naturally replicated lineages that provide a powerful model for studying adaptation and convergent evolution.
