Dispersal Behavior Of Mosquitofish (gambusia Holbrooki)
… ecosystems that they inhabit. Information on dispersal behavior will help better understand and predict mosquitofish metapopulation dynamics and invasions. I experimentally tested dispersal behavior of individual mosquitofish under a range of laboratory conditions relevant to field situations. …

DISPERSAL BEHAVIOR OF WHITE-TAILED DEER IN AN AGRICULTURAL LANDSCAPE
White-tailed deer (Odocoileus virginianus) dispersal and excursion movements impact gene flow, population dynamics, and disease spread. Knowledge of movement characteristics and habitat selection during dispersal could provide the ability to predict how deer may relocate themselves within the …

Connections between individual dispersal behavior and the multi-scale distribution of a saproxylic beetle
… among species traits (e.g., mobility and behavior), intra- and inter-specific interactions, quality and configuration of the landscape, and historical events. Determining which factors are most important to incidence is difficult because the multiple processes affecting incidence operate …

Mister Parid's Neighborhood: Dispersal Behavior and Flocking Dynamics of the Social Black-crested Titmouse (Baeolophus atricristatus)
… family flocking groups due to delayed juvenile dispersal each summer. A recently elevated species, separated from its sister-taxon, the tufted titmouse (Baeolophus bicolor), the BCTI is an ideal model species for studying family-flocking dynamics. The three goals of my project were to: (1) …

White storks (Ciconia ciconia) of Eastern Germany: age-dependent breeding ability, and age- and density-dependent effects on dispersal behavior
Dispersal behavior plays an important role for the geographical distribution and population structure of any given species. Individual’s fitness, reproductive and competitive ability, and dispersal behavior can be determined by the age of the individual. Age-dependent as well as density-dependent …

Impact of a Historical Translocation on Populations of White-Tailed Deer Odocoileus virginianus
… Low gene flow due to white- tailed deer dispersal behavior is likely to reduce the regional impact of translocations to a local scale.</p>

Behavioral syndromes and their effect on dispersal in Notonecta irrorata
Dispersal is an important life-history characteristic for many organisms, including in the genus of back-swimming insect Notonecta. The propensity to disperse is a behavior that might be affected by an individual's other behavioral tendencies. Correlated behavioral traits, or behavioral syndromes, …

Predicting Mobile Species Response to Landscape Structure: The Roles of Spatiotemporal Pattern and Individual Dispersal
… population performance; and that differences in dispersal behavior influence species vulnerability. Existing theory predicting population response to landscape alteration characterizes the landscape as habitat or non-habitat (binary)---even though organisms likely perceive a continuum of …

Assessment of a freshwater turtle reintroduction
… of reintroduction methodologies. I evaluated behavior, health, and demography of a reintroduced population of Alligator Snapping Turtles (Macrochelys temminckii) with reference to the suitability of this species for reintroduction and the prognosis of the reintroduction. Using radio telemetry, …

Investigations of the destructive behavior, and method for control of the lesser mealworm, Alphitobius diaperinus (Panzer), (Coleoptera: Tenebrionidae)
… house construction materials on lesser mealworm dispersal behavior. Larvae and adults preferred manure habitats of 30 and 40% moisture, and dispersal from the manure significantly increased when manure moisture was increased to levels of 50 and 60%. Larvae climbed a significantly greater distance …

Intrabrood Dominance Hierarchies in Juvenile Red-Cockaded Woodpeckers: The Role of Early Social Environment On Post-Fledging Survival and Natal Dispersal
… environment prior to fledging influenced male dispersal decisions and subordinates delayed dispersal in the spring in situations where all dominants died over the winter. The probability of delayed dispersal in females was higher for females raised without brood-mates in one of two populations …

Spatial Ecology of Entomopathogenic Nematodes with Contrasting Foraging Strategies
… studies have identified a dichotomy in foraging behavior of entomopathogenic nematodes (EPNs) but little is known about their dispersal patterns in the field. Overall goal of this dissertation research was to examine the dispersal behavior of two EPN species with contrasting foraging strategies, …

Survival, family breakups, and dispersal of yearling and subadult black bears in western Virginia
… survival rates, dates of family breakup, and dispersal patterns for yearling and subadult bears in hunted black bear (Ursus americanus) populations in North America are scarce. We estimated survival rates of yearling and subadult black bears from a hunted population in western Virginia during …

Bidirectional interactions between behavior and disease in banded mongooses (Mungos mungo) infected with Mycobacterium mungi
Behavior and disease interact bidirectionally and on multiple levels of host organization, and these interactions can have important consequences for population-level disease dynamics. I explored how behavior can both influence and respond to infectious disease in a banded mongoose population …

Aggregation, dispersal and edge behavior of the bark beetle predator Thanasimus dubius (Coleoptera: Cleridae); potential use in biological control
… dubius biology including both its chemical and dispersal ecology. I first present an experiment that was conducted to improve the rearing system of T. dubius so that sufficient numbers of predators could be produced more efficiently for both behavioral and ecological studies. Improvements to the …

DISPERSAL MECHANISMS OF EMBRYONIC AND LARVAL BURBOT (LOTA LOTA)
… that primarily rely on hydrodynamic forces for dispersal. However, allometric growth patterns and larval behavior also plays a significant role in dispersal. The developmental timeline of dispersal mechanisms in burbot (<em>Lota lota</em>) larvae is crucial to understanding where they may settle …
