Behavioral ecology of wild turkeys
… to a handful of studies. Lacking this important behavioral information, it remains unclear how incubation behavior among turkey hens influences reproductive success. Habitat use among hens during the reproductive season is influenced by forest management strategies such as prescribed fire, …

Radiotelemetry and Behavioral Ecology of Neonate Southern Pacific Rattlesnakes
… helleri,</em> I monitored the behavior and ecology of this understudied age-class and species. As an alternative to surgical implantation, external transmitter attachment was less invasive, permitted frequent transmitter replacement, and did not appear to affect neonate behavior. Five …

Behavioral ecology of coral reef fishes at spawning aggregation sites
… This thesis is an extensive investigation of the behavioral and ecological relations between spawning reef fishes, predators and their environment at a spawning aggregation site. Many hypotheses have been proposed regarding the adaptive nature of different diel reproductive cycles observed in …

Thermal and Behavioral Ecology of the Mexican Beaded Lizard (Heloderma horridum)
… rapidly. In this investigation, we describe the behavioral and thermal ecology of the Mexican beaded lizard (<em>Heloderma horridum</em>), which commonly weighs more than 1kg. This large body size means that this species has significant thermal inertia, which, depending on the characteristics of …

Chemical and Behavioral Ecology of the Coastal Giant Salamander (Dicamptodon tenebrosus)
Intraspecific interactions are an important factor in shaping the population structure of terrestrial salamanders. Both physical interactions and scent-marking are vital components to the establishment of territories and influence dispersion of individuals. However, little is known about the …

Behavioral Ecology and Associated Virology of Mosquito-Host Interactions in Southern California
… interactions are critical for understanding the ecology and epidemiology of mosquito-borne diseases. In this dissertation, I conducted three studies to explore potential mosquito-host interactions and associated virus infection rates. I first demonstrated that mosquito captures at CO2-baited …

Behavioral Ecology, Taxonomy, and Conservation Genetics of the Bahama Oriole (Icterus northropi)
… explored the population status and breeding ecology of the Bahama Oriole. My estimates of 141- 254 individuals remaining globally contributed to an IUCN Red List designation as "critically endangered." Orioles selected nesting trees that were significantly taller, less likely to have shrubs …

The Behavioral Ecology and Conservation of an Australian Passerine, the Brown Treecreeper (Climacteris picumnus)
This study addressed two aspects of ecological theory developed primarily in North America and examined these theories using an Australian passerine as a model species. The first theory concerns the mechanisms by which habitat fragmentation affects avian populations. I investigated the mechanisms …

Development, Growth, and Behavioral Ecology of Walleye as Influenced by Sublethal Exposure to Dietary Selenium
A decline in the walleye Stizostedion vitreum sport fishery in lower Lake Oahe, South Dakota, was documented in the early l 980's and has since been attributed to poor natural reproduction and/or recruitment. Contaminants are highly suspected in lower Lake Oahe because of the low natural …

Behavioral ecology of juvenile brown-headed cowbirds: implications for the evolution and maintenance of avian brood parasitism
Avian interspecific brood parasites are species that forego parental care and rely on heterospecifics to raise parasitic offspring. Host-parasite coevolutionary arms races and the constraints associated with a non-parasitic bird transitioning to a parasite likely contribute to the rarity of this …

Behavioral ecology of the Colorado brown tarantula (Aphonopelma hentzi): Activities displayed around the burrow through juvenile group dispersal
<p>The life history strategy of the Colorado brown tarantula (Aphonopelma hentzi) typically includes males spatially scattering in search for a female mate in the fall, followed by female attendance of fertilized eggs the following summer. Here, I highlighted aspects associated with this female …
