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 ...

Frontiers in Ecology and Evolution, 2021 The capacity of regenerating a new structure after losing an old one is a major challenge in the animal kingdom. Fish have emerged as an interesting model to study regeneration due to their high and diverse regenerative capacity.

Frontiers in Ecology and Evolution, 2021 Sexual conflict is caused by differences between the sexes in how fitness is maximized. These differences are shaped by the discrepancy in the investment in gametes, how mates are chosen and how embryos and young are provided for.

Light and electron microscopic morphology of the fertilized egg and fertilized egg envelope of Poropanchax normani, Poeciliidae, Teleostei [PDF]
Applied Microscopy, 2022 We examined the morphology of the fertilized egg and the fine structure of fertilized egg envelopes of Poropanchax normani belonging to the family Poeciliidae, also known as Norman’s lampeye using light and electron microscopes.

Species identity of Gambusia (Pisces: Poeciliidae) introduced to Slovenia
Natura Sloveniae, 2007 On the basis of morphology of the gonopodium and fin ray counts it was determined that the introduced mosquitofish in Slovenia belong to the species Gambusia holbrooki Girard, 1859 rather than G. affinis (Baird & Girard, 1858).

Faster Weight Growth in Invasive Mosquitofish <i>Gambusia holbrooki</i> and <i>Gambusia affinis</i> (Poeciliidae) Under Climate Change. [PDF]
Ecol EvolGlobal populations of western mosquitofish G. affinis are more sensitive to climatic variation than eastern mosquitofish G. holbrooki in terms of length‐weight allometries. Under climate change, the populations of G. affinis, especially those in East Asia and Eastern Europe, are expected to grow faster in weight, posing greater threats to native ...

Male Copulatory Structures in Reproductively Functional Female Live-Bearing Fish <i>Pseudopoecilia fria</i>. [PDF]
Ecol EvolWe recently discovered a population of the live‐bearing fish Pseudopoecilia fria (Cyprinodontiformes: Poeciliidae), in which females were found to possess gonopodia, reproductive organs normally exclusive to male fish that are used in the transfer of sperm in mating.
