Abstract:: Pheromones are chemical cues produced by organisms that affect the behavior and/or physiology of conspecifics. The orchestration of reproductive behaviors in many animals depends on the expression of sex pheromones. In insects, intraspecific variation in sex pheromone expression is commonly observed and often influences social interactions between individuals. To what...

Creator:: O'Donnell, Ryan P.
Abstract:: The benefits of reproduction are clear, but there are also costs. Much is known about the costs of reproduction in females, but only recently have male costs been investigated in any depth. These costs of reproduction may be minimized by appropriately modifying behavior, but there has been little research on...

Creator:: Greene, Michael John
Abstract:: In animals, reproductive behaviors serve to attract individuals together during the breeding season and to coordinate the behavioral and physiological states of individuals so that mating can successfully occur. In snakes, the various reproductive behaviors including courtship, mating, courtship inhibition, male combat and trailing are mediated primarily by pheromones. Pheromones...

Creator:: Moore, Ignacio T.
Abstract:: Animals respond to stressful situations with increases in plasma levels of glucocorticoid stress hormones. These hormones originate from the adrenal cortex in response to stimulation of the hypothalamic-pituitary-adrenal axis. Glucocorticoids (corticosterone in reptiles) function to mobilize energy and suppress unnecessary functions until the stress passes. Among these immediately unnecessary functions...

Creator:: Lerner, Darren T.
Abstract:: A wide range of environmental and physiological factors influence the type and extent of sexual dimorphism found in animals. Influential factors include variable climate, competition for resources and mates, mate choice, and parental investment. In addition, some investigators attribute differences in body size to physiological factors influenced by genetic and...

Creator:: Broadus, Lindsey J.
Abstract:: "Red-sided garter snakes, Thamnophis sirtalis parietalis, from Manitoba, Canada are known to be hosts to trematodes, Alaria sp., in their population. Alaria sp. have been located in the tail tissue of the snakes. The non-reproductive stage of these obligate endoparasites, known as a mesocercaria, is trophically acquired by garter snakes....
