Zoo Ecology of a Primate Species: Squirrel Monkey (Saimiri sciureus)
(2009-04-14)
Understanding how captivity affects the behavioral and development traits of a species is important for management and conservation in zoos. The ecology of squirrel monkeys (Saimiri sp.) may be different in captivity than ...
Host Specificity and Regional Endemicity in Symbiotic Dinoflagellates (Symbiodinium, Dinophyta) Associated with Sea Anemones in the Genus Aiptasia
(2009-04-13)
Recent investigations of coral reef biology have focused on the global biogeography and host specificity of Symbiodinium, a diverse group of dinoflagellates that symbiotically associate with many marine organisms, including ...
Identification of genes involved in the production of a novel antifungal agent (7, 10, 12-trihydroxy-8(E)-octadecenoic acid) in Pseudomonas aeruginosa
(2009-08-04)
The gram-negative bacterium Pseudomonas aeruginosa catalyzes the conversion of ricinoleic acid into a novel trihydroxy fatty acid, 7, 10, 12-trihydroxy-8(E)-octadecenoic acid (TOD), that has a potent antifungal activity ...
Female Mating Preference and Reproductive Success in Eastern Bluebirds: Interacting Effects of Plumage Coloration and Genetic Compatibility
(2009-12-18)
In my dissertation, I used a combination of aviary-based experiments, field experiments and correlational research to fully explore the importance of mate choice and environmental heterogeneity on reproductive success in ...
Mating Behavior of Columbian Ground Squirrels
(2008-09-09)
Columbian ground squirrels (Spermophilus columbianus) are diurnal, herbivorous, colonial, and hibernatory rodents that reside in the Rocky Mountains of western North America. During April-July in 2005-2007, field assistants ...
Spatial ecology of the eastern diamond-backed rattlesnake (Crotalus adamanteus)
(2008-09-09)
An animal’s spatial ecology may be governed by variables operating at more than one spatial scale, which underscores the importance of incorporating multiple spatial scales into habitat selection models. This is particularly ...
The Use of Ultrasound for Communication by the Big Brown Bat (Eptesicus fuscus)
(2008-09-09)
Communication signals are important regulators of mating behavior in many animals. Various pre- and post-copulatory mechanisms have been suggested to play a role in the reproductive success and mating strategies of many ...
Placement and recovery of seed caches by a solitary rodent, Ord's kangaroo rat (Dipodomys ordii)
(2008-09-09)
Seed caching is a common behavior that has important ecological consequences for seed-hoarding animals, granivorous competitors, and plants whose seeds are harvested and stored. Despite the significance of this behavior, ...
Yolk androgen deposition in two passerine species: Do females play favorites?
(2008-09-09)
Eggs of oviparous species contain variable amounts of androgens, such as testosterone (T), dihydrotestosterone (DHT), and androstenedione (A4). Previous studies in birds show that yolk androgens of maternal origin have ...
Role of Arabidopsis Thaliana Calmodulin Isoforms in Tolerance to Abiotic Stress
(2008-09-09)
Calmodulin and Ca2+ have been implicated in adaptation of plants to changes in its environment. Arabidopsis thaliana (Arabidopsis) genome has nine genetic loci encoding calmodulin protein isoforms. We have used wild type ...
