Sperm specificity and potential paternal effects in gynogenesis in the Amazon Molly (Poecilia formosa) [PDF]
PeerJ, 2023 The Amazon Molly (Poecilia formosa) reproduces by gynogenesis, a relatively rare form of asexual reproduction where sperm is required to trigger embryogenesis, but male genes are not incorporated into the genome of the embryo.

Evidence for cryptic speciation in directly transmitted Gyrodactylid parasites of Trinidadian guppies [PDF]
, 2015 Cryptic species complexes are common among parasites, which tend to have large populations and are subject to rapid evolution. Such complexes may arise through host-parasite co-evolution and/or host switching.

Phenotypic Variation in an Asexual-Sexual Fish System: Visual Lateralization
Frontiers in Ecology and Evolution, 2021 Sexual reproduction is nearly ubiquitous in the vertebrate world, yet its evolution and maintenance remain a conundrum due to the cost of males. Conversely, asexually reproducing species should enjoy a twofold population increase and thus replace sexual ...

Predator avoidance in extremophile fish [PDF]
, 2013 Extreme habitats are often characterized by reduced predation pressures, thus representing refuges for the inhabiting species. The present study was designed to investigate predator avoidance of extremophile populations of Poecilia mexicana and P ...

Convergent evolution of coloration in experimental introductions of the guppy (Poecilia reticulata). [PDF]
, 2018 Despite the multitude of examples of evolution in action, relatively fewer studies have taken a replicated approach to understand the repeatability of evolution.
