Conditioned Helplessness and Human Escape Behavior
… in human subjects, and, secondly, the amount of behavioral variability that can be accounted for in terms of locus of control as measured by Rotter's Internal-External control scale (I-E scale).

Effects of Sublethal Copper Exposure on Escape Behavior and Growth of Rana pipiens Tadpoles
… exposure to copper affects tadpole predator-escape behavior and how quickly tadpoles recover. After exposure, tadpoles were separated. Escape behavior was recorded for two-thirds of exposed tadpoles while one-third of the exposed population was measured weekly to determine growth and …

Tactical Escape Behavior and Performance of a Small Sceloporine Lizard in Two High Risk Habitats
… like woody debris or vegetation can alter escape paths and running performance. Additionally, these microhabitat features can influence behavioral tactics in complex environments. The ability to negotiate physical barriers in dense environments likely influences survivorship through …

Self-control as Response Produced Time-out from a Stimulus Associated with Reinforcement and Response Independent Shock
The problem: To control escape behavior (self-control) from a stimulus associated with response dependent food and response independent shock. Procedure: Five rats were trained in operant chambers to press a lever (lever A) for VI 30" food during one stimulus (S1) and never reinforced during …

The Effect of Habitat Fragmentation on Forest Mammals: An Experimental Analysis of Three Squirrel Distributions in the Agricultural Landscape of East Central Illinois
… rates of interpatch movement. A comparison of escape behavior between fox and gray squirrels demonstrated that the escape strategy of the gray squirrel is more suited to an urban environment, providing a possible explanation why gray squirrels displace fox squirrels in certain urban areas. This …

The Developmental and Behavioral Effects of Δ9-Tetrahydrocannabinol on a Spastic Mutant
… present study to examine the developmental and behavioral influences of THC on wild-type (WT) and bandoneon (<em>beo) </em>embryos and to compare these effects to those observed after exposure to Lorazepam, a common benzodiazepine used to mitigate spasticity in hyperekplexics. Since both THC and …

Nonlinear Dynamics of Energy Harvesting Ocean Buoys
… conditions. First, the bifurcation and stability behavior of inhomogeneous floating bodies is studied. Bifurcation diagrams and basins of attraction that illustrate the stability of the equilibrium positions as a function of the vertical position of the center of mass within the body are …

Effects of Prior Exposure to Predatory Chemical Cues on Territorial and Foraging Behaviors of the Ozark Zigzag Salamander, Plethodon Angusticlavius
… salamanders (Plethodon angusticlavius) make behavioral changes when in direct contact with predatory chemical cues. I predicted that prior exposure to a predator cue would also affect the subsequent behavior of these salamanders. I collected chemical cues from ringneck snakes (Diadophis …

The Effects of Amphetamine Exposure on Neurodevelopment and Behavior in Early Life Stages of Danio Rerio
… exposure impacts the development of stereotyped behaviors and the neural circuit that governs these behaviors. The zebrafish (<em>Danio rerio</em>) was used as our model organism because of the extensively studied developmental milestones these fish provide. Using escape responses as a behavior …

Variations in Time-Dependent Mosquito-Host Interactions Across Aedes Species
… that mediate this threat detection and escape behavior were examined, revealing a possible candidate for a giant fiber neuron in Aedes aegypti. Overall these results provide novel insights into mosquito biology that have the potential to be applied towards vector control methods.

Response to visual threats in Aedes aegypti mosquitoes
… is a need for a better understanding of their behavior so that new control solutions can be imagined, and existing ones can be improved. There has been a vast number of studies examining the host seeking behavior of mosquitoes, however there is a lack of knowledge concerning how mosquitoes are …

Influences of Anthropogenic Noise on Flight Initiation Distance, Foraging Behavior, and Feeder Community Structure of Wild Birds
… how anthropogenic noise impacts daily behavior as well as community structure of wild birds. In the first component of this thesis, I assessed the distance at which a bird initiates flight or escape behavior (i.e., flight initiation distance or FID) in varying acoustic conditions. I …

The generality of learned helplessness theory: effect of electroconvulsive shock
… were randomly assigned to one of three groups: escape, yoked-inescapable, and no shock control. Each rat in the escape group received 80 trials of unsignaled escapable shock. The escape group rats were required to perform a progressive fixed-ratio bar press to escape shock. The yoked-inescapable …

The Ontogeny of Escape Responses and Locomotor Performance in Sceloporus Woodi
… distance including ontogenetic stage, ability to escape, and the degree of crypsis. Of these, the ontogenetic effects on escape velocity and flight initiation distance are likely to be substantial. Juvenile and hatchling animals typically have a lower absolute velocity than adults. If escape …
