Fish treated with AVT were less aggressive than the control fish. Photos by S.

Seven taxa The hormone, arginine vasotocin (AVT) is a of pupfish occur in Death Valley, each uniquely adapted neurotransmitter that modulates behavior in some fish to its particular habitat, and all exhibiting remarkable species. Dr. Lema observed differences in neural AVT phenotypic plasticity—significant morphological and phenotype between populations of pupfish, and showed behavioral differences are evident within a couple of that AVT influences pupfish behavior. He then generations in response to small environmental changes demonstrated that the AVT system in pupfish is in their unique habitats.

The AFS promotes scientific research and enlightened management of aquatic resources for optimum use and enjoyment by the public. It also encourages comprehensive education of fisheries scientists and continuing on-the-job training. AFS FISHERIES EDITORS OFFICERS STAFF PRESIDENT SENIOR EDITOR ScIEncE EDITORS William G.
