The Influence Of Predation Risk On The Foraging And Territorial Behavior Of The Ozark Zigzag Salamander (Plethodon Angusticalvius)
… is high, animals often decrease the frequency of behaviors associated with feeding, territorial defense, and reproduction. I examined the potential for such trade-offs in the Ozark zigzag salamander, Plethodon angusticlavius. I performed a series of laboratory experiments to determine whether …

Territoriality and habitat selection of feral pigs on Fort Benning, Georgia, USA
… to test our hypotheses that feral pigs were territorial at the sounder level and that territoriality was a key factor influencing habitat selection of feral pigs. I used Global Positioning System (GPS) location data from 24 individuals representing 18 sounders combined with mark-recapture and …

Factors Affecting Behavioral Variation of Individual Glaucous-Winged Gulls (Larus Glaucescens) While on Territory
<p>Factors affecting the patterns of behavior of individual Glaucous-winged Gulls <em>(Larus glaucescens)</em> on Protection Island, Jefferson County, Washington were examined. Males were found to be present on territory often than females. Proportions of behavior varied by time of season. Gulls …

Chemical and Behavioral Ecology of the Coastal Giant Salamander (Dicamptodon tenebrosus)
… the first accounts of agonistic and display behavior of terrestrial <em>D. tenebrosus</em>. These results suggest that terrestrial <em>D. tenebrosus </em>utilize chemical cues in their selection of refuge sites, and that they also display aggressive, territorial behavior.

Extra-pair paternity within the female-defense polygyny of the lizard, Anolis carolinensis: Evidence of alternative mating strategies
… males compete directly for females through territorial behavior. Inter-male competition is intense due to an average polygyny ratio of 1 male to 3 females despite a 1:1 adult sex ratio. Through high levels of territorial behavior (e.g., 100 displays/h, 27 m patrol distances/h, 70% of day in …

Seasonality and trade-offs in equatorial rufous-collared sparrows (Zonotrichia capensis)
… Chapter II, I investigated the function of male territorial aggression. Males had peak territorial aggression scores during pre-breeding and nesting, suggesting that paternity protection and food resource defense are the primary selective forces shaping male territorial behavior. Territorial …

The ecological, behavioral, and genetic factors influencing the diversification of Lake Malawi's rock -dwelling cichlids
… communities are identified by examining male territorial behavior and habitat utilization within Metriaclima. By observing the recolonization of artificially vacated territories, I show that (1) territories are species-specific and (2) this species-specificity is associated with the width of …

Territoriality and Scent Marking Behavior of African Wild Dogs in Northern Botswana
… wild dogs do not vocalize as a form of territorial advertisement so to explore mechanisms of communication and movement behaviors, I radio collared and observed a population of wild dogs in northern Botswana, to collect fine-scaled, contemporaneous movement data on neighboring packs of …

Behavioral and genetic correlates of reproductive success in male addax (Addax nasomaculatus, De Blainville 1816)
… Very little is known about their general behavior and social structure, either in the wild or in captivity. This study examined the behavior of semi-free ranging herds of addax to establish the mating strategies male addax pursue to increase their reproductive success. This study …

Factors Influencing Ectoparasitism on Western Fence Lizards (Sceloporus occidentalis): Host Sex, Testosterone, Reproductive Condition, and Behavior
… sex, hormonal state, reproductive condition, and behavior. It has been observed in several vertebrate taxa that males have higher ectoparasite intensities than females and males with increased testosterone have increased ectoparasite intensities. One potential reason for these observations is that …

Natural and Experimental Noise Affects Acoustic Communication in Songbirds
