Predator recognition and anti-predator behavior in juvenile Asian carp
… many prey fishes. Chemical, social, and similar predator cues may all inform an individual of a possible impending predatory threat. Bighead (Hypophthalmichthys nobilis) and silver carp (H. molitrix) widespread invasive fishes, and can be vulnerable to predation during their first year. Because …

Effects of Urbanization on Survival Rates, Anti-Predator Behavior, and Movements of Woodchucks (Marmota Monax)
… need a better understanding of demographic and behavioral responses by mammals to urbanization including those species that could be urban adapters. Furthermore, past research has focused on carnivores, but herbivores could respond to additional factors across urbanization gradients such as …

HUMAN PREDATION RISK AND ELK BEHAVIOR IN HETEROGENEOUS LANDSCAPES
… known about the indirect effect hunting has on anti-predator behavior, movement, resource selection, and human-elk conflicts. We first investigated the indirect effects of hunting on elk using an extensive comparison of elk anti-predator behavior across four human predation risk levels in …

Phenotypic Consequences of Gestation Temperature in the Northern Watersnake, Nerodia Sipedon
… snakes, offspring morphology, locomotor speed, anti-predator behavior, and growth are known to be affected by developmental temperature and are likely to have important fitness consequences. I explored the influence of gestation temperature on offspring phenotypes produced by gravid Northern …

The Effects Of Acidic Conditions And Tannins On The Survival, Development, And Behavior Of Cope’s Gray Treefrog (Hyla Chrysoscelis)
… environmental changes is greatly mediated by behavior, and recent studies indicate that anthropogenic acidification impairs behavioral responses by impacting olfactory abilities of aquatic organisms. Responding appropriately to novel stimuli is important for individual performance and …

Effects of Turbidity on Anti-Predator Response and Foraging Behavior in the Fountain Darter, Etheostoma fonticola
… visual ability resulting in altered animal behavior. Anti-predator response and successful foraging ability, both essential elements of ecological communities, are two aspects of behavior that can be affected by turbidity. The federally endangered fountain darter (Etheostoma fonticola) is an …

Mating behavior and the effects of turbidity on preferences for size in the fountain darter, Etheostoma fonticola
… in aquatic communities and may affect the behavior of individual animals, including altering foraging and anti-predator behavior as well as mating preferences. The fountain darter, Etheostoma fonticola, is federally endangered making it an especially important species for examining the …

Anti-Predator Responses of Squid Throughout Ontogeny
… sensory modalities and a complex array of escape behaviors have evolved as components of anti-predator responses in squids. The goals of this study include: (1) examine the role of the lateral line analogue and vision in successful predator evasion; (2) measure kinematics of escape jetting; (3) …

Prey preference for Asian carp and soft plastic lure ingestion by largemouth bass
… and silver carp. Observations of prey and predator behavior were quantified in a 720-L aquarium and variation in anti-predator behavior explained relative differences in vulnerability to predation. Differences in vulnerability to predation may explain the greater invasion success of silver …

Habitat Selection in Four Sympatric Small Mammal Species and the Effects of Potential Predators on Peromyscus Leucopus
I examined the effects of potential predators in relation to habitat selection in Peromyscus leucopus. I also examined habitat selection in three other sympatric species (Blarina brevicauda, Blarina carolinensis, Sorex longirostris). I utilized data fiom 49 sampling sites on National Park Service …

Variation in predator communities and anti-predator behaviors of Milne-Edwards' sifakas (Propithecus edwardsi) in southeastern Madagascar
… human-disturbed habitats. I investigated lemur-predator interactions in southeastern Madagascar through a comparison of predator communities and anti-predator behaviors of Milne-Edwards' sifakas (Propithecus edwardsi) in the continuous rainforest of Ranomafana National Park, and the forest …

Vocal responses of adult Eastern Bluebirds (Sialia sialis) to potential nest predators and the behavioral responses of nestlings
… information about the threat posed by potential predators. However, few investigators have examined the responses of nestlings in cavity nests to the anti-predator vocalizations of adults. Therefore, the objectives of my study of cavity-nesting Eastern Bluebirds <em>(Sialia sialis)</em> were to …

Early Life History of Yellow Perch in Eastern South Dakota Lakes
… cladoceran Diaphanosoma birgei by 14-mm TL. Substantial numbers of large Cladocera were not present in the Pelican Lake environment and therefore additional dietary transitions did not occur until the fish reached advanced juvenile stages. Juvenile yellow perch were sampled by seining in mid-July …
