..., the influence of specialization on this relationship is unclear. We used divergent populations of Trinidadian guppies ( Poecilia reticulata ) to test whether integration during suction is generalizable to a non-suction specialist and whether intraspecific specialization of component systems affects...

... the link between mate choice and cognitive ability is necessary to fully understand mate choice. To experimentally study this link, we used guppies ( Poecilia reticulata ) artificially selected for divergence in relative brain size and with previously demonstrated differences in cognitive ability...

... latitude, tropical ectotherms live close to their thermal limits, and are thus particularly vulnerable to increases in temperature. In this study, we examined how predicted patterns of global warming will affect survival and sexual traits in the Trinidadian guppy ( Poecilia reticulata ). Guppies were...
