Regulation of Behavioral Plasticity: Mechanism Underlying Olfaction-Dependent Changes in Male Specific Courtship Behaviors in Drosophila melanogaster
<p> Animal behaviors consists of both innate and plastic components. Hardwired neural circuits are established during development and confer animals the innate potential to solve the survival challenges. However, in an ever-changing environment, animals need to modify their behaviors constantly and …

Infants' reasoning about animals
… are the developmental origins of our concept of animal? There has long been controversy concerning this question. At issue is whether biological reasoning develops from earlier forms of reasoning, such as physical and psychological reasoning, or whether from a young age children reason about …

Categorical organization and machine perception of oscillatory motion patterns
Many animal behaviors consist of using special patterns of motion for communication, with certain types of movements appearing widely across animal species. Oscillatory motions in particular are quite prevalent, where many of these repetitive movements can be characterized by a simple sinusoidal …

A Bayesian approach to discovery of latent dependency in point-referenced data
… a statistical model accounting for collective animal movement. The model highlights how to incorporate the ecological perspective into the hierarchical modeling structure, motivating the need of considering the underlying ecological structure to better understand the driving dynamics in the …

Animal Motion Analysis and Approximation for Robotics
As the robotic industry has matured, the study of animal motion has given rise to many robot designs. Researchers from multiple areas, such as biomechanics, control theory, and machine learning, have spent their energy and efforts making robots more realistic. The intent is that the automatic …

Correlating Behavior and Physiology of Sand Fiddler Crabs, UCA Pugilator
… may be the proximate cause of some animal behaviors. To investigate this claim we conducted two studies examining the relationship between physiology, via internal energy stores, and behavior in the sand fiddler crab,Uca pugilator. Energy stores were quantified through determination …

Mass spectrometry-based characterization of cell-to-cell signaling molecules in the nervous system
… in a wide range of physiological events and animal behaviors, such as pain sensation, food intake, memory, circadian rhythm, tissue regeneration and drug addiction. Cell-to-cell signaling molecules are highly diverse in structure or sequence and their quantities are different at various time …

Analysis of D-amino acid-containing neuropeptides in mollusks and rodents
… structures. These neuropeptides have evolved for animal behaviors and regulating neuronal circuits. Neuropeptides exert their responses through GPCRs in most cases, and in order to interact with the GPCR, their structure is important. Their structures are not solely defined by their peptide …

Tracking and monitoring marine animals with vision-guided underwater vehicles
Marine animals constitute an estimated 80% of all animal biomass on Earth, with nearly one- to two-thirds of marine species still undescribed to science and much of the ocean at depth remains underexplored. Even among the species we know, for many, we have few observations and limited understanding …

Human and Animal Behavior Understanding
Human and animal behavior understanding is an important yet challenging task in computer vision. It has a variety of real-world applications including human computer interaction (HCI), video surveillance, pharmacology, genetics, etc. We first present an evaluation of spatiotemporal interest point …

Fluid Dynamics in Liquid Entry and Exit
… sea-to-air projectiles. It is also crucial in animal behaviors like the locomotion of water-walking animals, the plunge-diving of birds, and the jumping out of water of marine creatures. Depending on the moving direction of a solid, such diverse phenomena can be classified into two categories; …

Modeling temporal coordination in speech production using an artificial central pattern generator neural network
… a type of neural circuit which underlies other animal behaviors. Included in this thesis are a description of the model, named the Neural Oscillator Model of Speech Timing and Rhythm (NOMSTR), and three empirical studies designed to test NOMSTR’s usefulness as a tool to model interactions …

Determining how stable network oscillations arise from neuronal and synaptic mechanisms
Many animal behaviors involve the generation of rhythmic patterns and movements. These rhythmic patterns are commonly mediated by neural networks that produce an oscillatory activity pattern, where different neurons maintain a relative phase relationship. This thesis examines the relationships …

Tracking Toads: Movement Patterns of Gulf Coast Toads (Incilius nebulifer) and the Urban Environment
Gulf Coast Toads (Incilius nebulifer) are a familiar urban resident in the southeast United States and Mexico. As urbanization increases, the Gulf Coast Toad may be expanding its range. Studying movement behavior can reveal how invasive a species may be and is a key factor in understanding the …
