Sexual conflict and sexually dimorphic cognition—reviewing their relationship in poeciliid fishes
ME Cummings - Behavioral Ecology and Sociobiology, 2018 - Springer
Sexual conflict, the difference in preferred mating rates between the sexes, often leads to
sexually dimorphic morphologies, strategies, and behaviors. We are now beginning to …

Does brain asymmetry allow efficient performance of simultaneous tasks?
Rogers (2000, Brain and Language, 73, 236–253) suggested that the ubiquity of cerebral
lateralization could be explained by the advantages it provides to individuals in coping with …

Quantity discrimination in female mosquitofish
The ability in animals to count and represent different numbers of objects has received a
great deal of attention in the past few decades. Cumulative evidence from comparative …

Emergence and development of personality over the ontogeny of fish in absence of environmental stress factors
G Polverino, C Cigliano, S Nakayama… - Behavioral Ecology and …, 2016 - Springer
Animals typically display among-individual differences in behavior that are consistent over
time (ie, personality). These differences are often triggered by variable individual responses …

Sexual harassment in live-bearing fishes (Poeciliidae): comparing courting and noncourting species
Sexual harassment by males has been reported from several live-bearing fishes
(Poeciliidae) and has been shown to inflict costs on females. For example, poeciliid females …

Context is key: social environment mediates the impacts of a psychoactive pollutant on shoaling behavior in fish
Behavior-modifying drugs, such as antidepressants, are increasingly being detected in
waterways and aquatic wildlife around the globe. Typically, behavioral effects of these …

Sex differences in cognitive performance and style across domains in mosquitofish (Gambusia affinis)
KJ Wallace, RT Rausch, ME Ramsey, ME Cummings - Animal Cognition, 2020 - Springer
Given that the sexes often differ in their ecological and sexual selection pressures, sex
differences in cognitive properties are likely. While research on sexually dimorphic cognition …

Lateralized female topminnows can forage and attend to a harassing male simultaneously
Animals engaged in a complex task are often unable to allocate enough attention to a
second concurrent task. We tested the hypothesis that cerebral lateralization is …
