Horseradish peroxidase (HRP) was used to identify parts of the presumptive neural pathway for gill cover erection, a behavioral display pattern performed by Siamese fighting fish (Betta splen

We determined the time of origin of neurons in the olfactory bulb of the South African clawed frog, Xenopus laevis . Tritiated thymidine injections were administered to frog embryos and tadpoles from gastrulation (stage 11/12) through metamorphosis (

Dominance behaviour and factors influencing dominance were investigated in small heterosexual and homosexual groups of guppies ( Poecilia reticulata ) in the laboratory. Straight line nip-right hierarchies were the most frequent type of dominance rel

Androgenic steroids have been implicated in the development of sex differences in Xenopus laevis frogs. In order to determine when neurons first acquire the ability to concentrate androgen, we prepared autoradiograms of CNS in developing frogs follow

Horseradish peroxidase was used to identify motor neurons projecting to the adductor mandibulae, levator hyomandibulae, levator operculi, adductor operculi, and dilator operculi muscles in Siamese fighting fish, Betta splendens. These muscles partici

We examined possible contributions of neurogenesis to sex differences in the vocalization pathway of the South African clawed frog, Xenopus laevis. Birthdates of neurons were obtained from autoradiograms of animals receiving tritiated thymidine from

We compared ectoparasite (Dissonus sp. copepods) infection levels on Pomacentrus vaiuli host fish from patch reefs with and without Labroides dimidiatus cleaning wrasses. Labroides appeared to prey selectively on larger individuals of Dissonus, reduc

Radio-tracer studies demonstrate that Labroides phthirophagus ingests considerable amounts of mucus from the surfaces of its hosts. Analysis of the quantity and gross chemical composition of host mucus reveals species specific differences. Host speci
