Long‐Term Sperm Storage in a Superfetatious Live‐Bearing Fish (Poeciliopsis gracilis, Poeciliidae) [PDF]
Ecology and EvolutionSperm storage is a post‐copulatory strategy by which females can improve their fecundity by creating asynchrony between mating and fertilization. Sperm storage duration varies across vertebrate species, wherein longer sperm storage is thought to coincide

The Morphogenesis of Sperm Storage Micropockets in the Western Mosquitofish (Gambusia affinis) [PDF]
AnimalsSperm storage within the female reproductive tract is widespread among animal species with internal fertilization, such as the fish family Poeciliidae, wherein the females possess a sperm storage micropocket (SSP) that can store sperm for up to a year ...

Standardized Approach to Life History Data Collection in Poeciliid Fishes [PDF]
Ecology and EvolutionLivebearing fishes in the family Poeciliidae have been essential to testing life history theory. These species are remarkable because males internally inseminate females, and females give birth to free‐swimming young, making these fishes amenable to ...

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 ...
