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.

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.

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 ...

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 ...

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.

Does personality affect premating isolation between locally-adapted populations? [PDF]

, 2016
Background: One aspect of premating isolation between diverging, locally-adapted population pairs is female mate choice for resident over alien male phenotypes.

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.
