The Digestive Microbiome Diversity of the Least Killifish, Heterandria formosa, and Its Implications for Host Adaptability to Varying Trophic Levels. [PDF]
Environ Microbiol RepInvestigations of environmental factors influence on the gut microbiome of the least killifish reveal high variability in gut microbiomes between disparate sites and higher microbial diversity in healthier habitats as reported by the Florida Department of Environmental Protection. Findings suggests specific microbial taxa that may aid in bioremediation

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 ...

Molekulargenetische und zytogenetische Untersuchungen zur paternalen Introgression beim gynogenetischen Amazonenkärpfling, Poecilia formosa [PDF]
, 2001 One of the greatest challenges in evolutionary biology is explaining the widespread occurrence of sexual reproduction and the associated process of genetic recombination. Comparing the advantages and disadvantages of sexual and asexual reproduction is expected to give major insights to that "queen of questions".

Casanovas are liars : behavioral syndromes, sperm competition risk, and the evolution of deceptive male mating behavior in live-bearing fishes [version 2; referees: 2 approved, 1 approved with reservations] [PDF]
, 2013 Male reproductive biology can by characterized through competition over mates as well as mate choice. Multiple mating and male mate choice copying, especially in internally fertilizing species, set the stage for increased sperm competition, i.e., sperm ...

Behavioural individuality in clonal fish arises despite near-identical rearing conditions. [PDF]
, 2017 Behavioural individuality is thought to be caused by differences in genes and/or environmental conditions. Therefore, if these sources of variation are removed, individuals are predicted to develop similar phenotypes lacking repeatable individual ...

Female mating preferences in blind cave tetras Astyanax fasciatus (Characidae, Teleostei). [PDF]
, 2006 The Mexican tetra Astyanax fasciatus has evolved a variety of more or less color- and eyeless cave populations. Here we examined the evolution of the female preference for large male body size within different populations of this species, either surface-

Automictic Reproduction in Interspecific Hybrids of Poeciliid Fish [PDF]
, 2007 SummaryAutomixis, the process whereby the fusion of meiotic products restores the diploid state of the egg, is a common mode of reproduction in plants but has also been described in invertebrate animals [1, 2].
