Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Escape responses in fishes provide insight into accelerative motions and behavioural response times of these animals, linking numerous fitness‐related traits. We sought to connect escape response performance to genotype and phenotype across ontogenetic stages within a single population of threespine stickleback (Gasterosteus aculeatus L.) to ...

Experimentally testing the function of anal fins in the bluefin killifish, Lucania goodei

open access: yesJournal of Fish Biology, EarlyView.
Abstract Anal fins are thought to affect many functions, including swimming, sperm flow and signalling. However, there are few experimental demonstrations of these functions. We manipulated male anal fins by placing a cut in the fin. We found that cut males had lower fertilization rates than uncut males.

Nonapeptide cell size differs between male morphs of the West African cichlid, Pelvicachromis pulcher

open access: yesJournal of Fish Biology, EarlyView.
Abstract Alternative male morphs are found in many species of fishes. These morphs often differ in suites of social behaviours, such as aggression and territoriality, associated with alternative reproductive tactics. Such consistent morph‐typical behavioural profiles suggest common differences in underlying neuroendocrine mechanisms.
