Predatory sequence learning for synthetic characters
The process of mammalian predatory sequence development offers a number of insights relevant to the goal of designing synthetic characters that can quickly and easily learn complicated and interesting behavior. We propose a number of principles for designing such learning systems, inspired by a …

Investor Behavior Surrounding Trading Halts: Short Sales, Predation and Contagion Effects
… the financial markets. In the first essay, the behavior of short sellers is examined surrounding interruptions in trading to determine if informed short sellers alter their trading patterns prior to and/or following a trading halt. This investigation also addresses the impact of short sales on …

Evolutionary co-option of trap-jaw ant mandible strikes: defensive interactions with antlions
… have examined evolutionary co-option at a behavioral level. Trap-jaw ants in the genus Odontomachus have a rapid and powerful mandible snap that is used during predation to disable fast or dangerous prey. Previous research suggests that some trap-jaw species may have co-opted the high …

The Computational Neuroethology of Weakly Electric Fish: Body Modeling, Motion Analysis, and Sensory Signal Estimation
… thousands of sensory afferents stimulated during behavior. I present research on sensory acquisition in weakly electric fish of the genus Apteronotus, where I overcame the first barrier by developing a markerless tracking system and have deployed a computational approach toward overcoming the …

Deception detection in dialogues
… interactions, such as bullying, trolling, or predatory behavior. Furthermore, such growing behaviors have most recently led to waves of fake news and a growing industry of deceit creators and deceit detectors. There is now an urgent need for both theory that explains deception and applications …

Invasion Ecology and Control Feasibility of the Jackson Chameleon (Trioceros jacksonii xantholophus) in Hawai‘i
… of habitat characteristics on form, function and behavior of an invasive lizard in Hawaii. In Chapters 1 and 2 I evaluate substantial variation in head-size and horn-length among and within islands, and between native and introduced ranges. Larger heads are associated with low precipitation, and …

Behavioral Evidence for "Contextual Decision Hierarchies" In the Hermit Crab, Pagurus samuelis
… and sensory cue perception influence the behavioral choices of hermit crabs. I began by reviewing behavioral experiments that have demonstrated the underlying sensory processing of visual, chemical, and tactile information in crustaceans and propose a novel behavior model entitled …

Participatory autocracy : private entrepreneurs, legislatures, and property protection in China
… government officials to report illicit predatory behavior. This signal, in turn, deters local officials from demanding bribes, ad hoc taxes, and other types of informal payments. I deploy both qualitative and quantitative methods to support the argument. First, to understand …

Managing the carnivore comeback: assessing the adaptive capacity of the Eurasian lynx (Lynx lynx) to cohabit with humans in shared landscapes
… With their large spatial requirements and predatory behavior, large carnivores are among the most difficult species to preserve in our modern day landscapes. Although large carnivores are usually considered as the epitomes of wilderness, because of human population growth and habitat …

Feline Obesity: Food Toys and Owner Perceived Quality of Life During a Prescribed Weight
… enrichment, allow cats to express their natural predatory behavior and overall improve owner-perceived quality of life. Therefore, we set out to investigate the role of food toys in owner-perceived quality of life of obese cats during a prescribed weight loss plan. Fifty-five cats with a BCS > 7 …

Coevolution Between Grasshopper mice (Onychomys spp.) and Bark and Striped Scorpions (Centruroides spp.)
… and a potentially lethal prey will result in behavioral and physiological adaptations that reciprocally mediate their interaction (i.e., coevolution). Bark scorpions (Centruroides exilicauda) and striped scorpions (Centruroides vittatus) produce a potent venom containing neurotoxins that …

The Roles of Ca2+ and cAMP in the Nematocyst Discharge of the Sea Anemone Tentacle
<p>The phylum Cnidarians are aquatic animals, including jellyfish, hydra, sea anemones, and corals. They are the simplest metazoans having a nervous system and are diploblastic. Cnidarians are obligate predators that capture prey using specialized stinging cells called cnidocytes. The cnidocyte …
