Mosquito responses to lethal and nonlethal effects of predation and an insect growth regulator

open access: yesEcosphere, Volume 12, Issue 3, March 2021., 2021
Abstract Lethal and nonlethal effects of predation are likely to impact phenotypic traits of potential prey that elude capture. Nonlethal effects of predation on prey can include alterations in behavior or morphology in response to predation risk which may impair prey growth and fitness.

Predator avoidance in extremophile fish [PDF]

open access: yes, 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 ...

Female mating preferences in blind cave tetras Astyanax fasciatus (Characidae, Teleostei). [PDF]

open access: yes, 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-

Predator-induced changes of female mating preferences: innate and experiential effects [PDF]

open access: yes, 2011
Background: In many species males face a higher predation risk than females because males display elaborate traits that evolved under sexual selection, which may attract not only females but also predators. Females are, therefore, predicted to avoid such

Inner ear morphology in the Atlantic molly Poecilia mexicana [PDF]

open access: yes, 2011
Fishes show an amazing diversity in hearing abilities, inner ear structures, and otolith morphology. Inner ear morphology, however, has not yet been investigated in detail in any member of the diverse order Cyprinodontiformes.

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

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