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-

Convergent recombination suppression suggests role of sexual selection in guppy sex chromosome formation. [PDF]

, 2017
Sex chromosomes evolve once recombination is halted between a homologous pair of chromosomes. The dominant model of sex chromosome evolution posits that recombination is suppressed between emerging X and Y chromosomes in order to resolve sexual conflict.

Standardized Approach to Life History Data Collection in Poeciliid Fishes. [PDF]

Ecol Evol
Research on livebearing fishes has been instrumental in the development of several elements of life history theory through empirical studies. We posit that a standardized approach to life history data collection within this singular system is needed to address the current important questions in life history evolution through large comparative studies ...

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 ...

Perceived Risk of Predation Affects Reproductive Life - History Traits in Gambusia holbrooki, but Not in Heterandria formosa [PDF]

, 2014
Key to predicting impacts of predation is understanding the mechanisms through which predators impact prey populations. While consumptive effects are well-known, non-consumptive predator effects (risk effects) are increasingly being recognized as ...

Adaptive capabilities and fitness consequences associated with pollution exposure in fish [PDF]

, 2016
Many fish populations are exposed to harmful levels of chemical pollution and selection pressures associated with these exposures have led to the evolution of tolerance.

Analysis of a possible independent origin of triploid P. formosa outside of the Río Purificación river system

Frontiers in Zoology, 2007
Background Unisexuality, or all female reproduction, is rare among vertebrates. Studying these exceptional organisms may give useful information with respect to the evolution and maintenance of sexual reproduction.

Shared and species-specific patterns of nascent Y chromosome evolution in two guppy species [PDF]

, 2018
Sex chromosomes form once recombination is halted around the sex-determining locus between a homologous pair of chromosomes, resulting in a male-limited Y chromosome.

Do female association preferences predict the likelihood of reproduction? [PDF]

, 2010
Sexual selection acting on male traits through female mate choice is commonly inferred from female association preferences in dichotomous mate choice experiments.

Poecilia mexicana is the Recent Female Parent of the Unisexual Fish P. formosa [PDF]

Evolution, 1991
Poecilia formosa, a small live-bearing fish native to northeastern Mexico, was the first recognized vertebrate with unisexual reproduction (Hubbs and Hubbs, 1932). This all-female "species" produces diploid apomictic eggs (Rasch et al., 1982; Monaco et al., 1984), and embryogenesis is subsequently activated by sperm from a related bisexual species ...
