(2019-07-17)Hybridization is a common phenomenon with important evolutionary consequences. It may result in the loss of genetic differentiation between groups, or serve to reinforce reproductive barriers between species. Hybridization ...

(2009-05-15)Cotesia are parasitoid wasps (Hymenoptera: Braconidae) that are used for biological control of pest moths (Lepidoptera: Noctuidae, Pyralidae) that damage agricultural crops. This dissertation investigated courtship acoustics ...

(2017-07-03)Mate-choice related behaviors are highly variable and sensitive to a wide array of environmental and social factors. Therefore, the stability of a given behavior can largely depend on the level of environmental variability ...
-
(2009-05-15)Swordtail fishes of the genus Xiphophorus have been studied as a model of sexual selection for many years. Many single-trait manipulation studies have been performed, determining female preferences for individual male ...
-
(2015-07-31)Hybridization represents a collision of genomes that can introduce new genetic and phenotypic variation into a population. Depending on the environment, this may lead to increased individual fitness and allow for integration ...
-
(2012-04-23)Mate choice behavior underlies many significant phenomena in biology including sexual conflict, selection, hybridization and speciation. Members of the genus Xiphophorus provide an excellent model for studying these processes ...

(2014-04-14)Learned mate choice has a fundamental role in population dynamics and speciation. Social learning plays a ubiquitous role in shaping how individuals make decisions. Learning does not act on a blank slate, however, and ...

(2011-04-26)We investigated the mechanisms behind reproductive allocation in sheepshead swordtail fish (Xiphophorus birchmanni). Classic life history theory predicts a trade-off between offspring size and number such that females with ...
