Small effective population sizes of two remnant ocelot populations (Leopardus pardalis albescens) in the United States
Threatened populations are vulnerable to the effects of genetic drift and inbreeding, particularly when gene flow is low and the effective population size is small. Estimates of effective population size (Ne) provide important information on the status of endangered populations that have experienced severe fragmentation and serve as indicators of genetic viability. Genetic data from […]
Seasonal change in female choice for male size in the two-spotted goby
Mate choice may vary according to various factors, such as mate availability and variation in mate quality. We tested seasonal changes in female choice regarding male size in a marine fish, the two-spotted goby, Gobiusculus flavescens. In this species, males occupy nests in which females lay their eggs and males thereafter provide exclusive parental care […]
Behavioral response of 12 ungulate species in captivity to the presence of humans
Abstract 10.1002/zoo.1430080308.abs Twelve species of captive ungulates were studied to determine behavioral responses to the presence of a zookeeper within the exhibit and in front of the exhibit, with and without zoo visitors present. Significant differences in behavior occurred between species for nearly all behaviors observed. A significantly greater occurrence of vigilance and approach behavior […]
