Exploiting Sugar Feeding Behaviors For Mosquito Control
… been conducted on hematophagy and host-seeking behaviors, but relatively little is known about phytophagy. Sugar feeding is an essential aspect of mosquito biology. Both male and female mosquitoes must consume sugar as a primary fuel source. Mosquitoes use olfactory and visual cues among other …

Kinetics and Energetics of Feeding Behaviors in Daubentonia madagascariensis
… the ways Daubentonia uses its specialized feeding apparatus during naturalistic feeding behaviors. This can be divided into two main objectives. The first objective was to better understand how these extreme specializations function in the extractive foraging niche of Daubentonia. The …

Evolution of Pharyngeal Feeding Behaviors in Free-Living Soil Nematodes
The file named "ChiangJian-Tzyh.pdf" is the primary dissertation file. All other files ("*.mpg") are supplemental files and may be viewed individually.

Integration of Homeostatic and Hedonic Brain Centers in the Regulation of Feeding Behaviors
… Both diseases are driven by maladaptive feeding behaviors, namely pathological overconsumption of high-fat food. Pathological overconsumption of high-fat food is potentiated by aberrant homeostatic feeding behavior (i.e. titration of caloric intake), which typically associates with …

Associations Between Postpartum Depression and Child Overweight and Obesity: Mediating Effect of Maternal Feeding Behaviors and Beliefs
… with their children, which could extend to feeding practices influencing weight gain. The prevalence and severity of childhood overweight and obesity is a global public health problem. An increase in weight gain in infancy can be the initiation of childhood and adult overweight and obesity. …

Intra-nacc adenosine and its role in mediating palatable food intake: interactions with striatal opioids
… circuitry and associated psychomotor and feeding behaviors. However, it is currently unknown to what extent striatal adenosine receptors differently contribute to the extensively studied nucleus accumbens opiate-induced feeding behavior. The present study investigated the intra-NAcc …

Investigating the Enteroendocrine - Brain Axis: Ghrelin Cell and ECL Cell Physiology and Ghrelin Action on Mood and Complex Eating
… hormone ghrelin act to regulate homeostatic feeding is fairly well documented. However, less understood are the mechanisms and brain regions that mediate ghrelin's effects on mood and complex eating behaviors. At the cellular level, little is known about the ghrelin cell's transcriptional …

Identification and Delineation of Neuronal Pathways Underlying Hypophagia
… animal research related to eating disorders and feeding behaviors, the majority of neuroscientists still examine how the hypothalamus regulates hunger-driven and satiety-regulating feeding behaviors.</p> <p>This body of work includes two projects I led and conducted on mice during the PhD …

Understanding ARFID: clinical characteristics of patients who meet avoidant/restrictive food intake disorder criteria in a multidisciplinary pediatric growth and nutrition clinic
INTRODUCTION: Feeding difficulties are commonly multifactorial in nature, and no uniformly agreed-upon classification system for feeding difficulties currently exists. The Diagnostic and Statistical Manual of Mental Disorders (DSM)-V included a new diagnosis called Avoidant/Restrictive Food Intake …

Comparison of Semi-Captive and Wild Gray-Shanked Douc Langurs’ (Pygathrix Cinerea) Activity Budgets
… assessed the group members' activity budgets and feeding behaviors and compared my data to that obtained in a study of wild GSD langurs. I collected data using instantaneous scan sampling at 2 minute intervals (Altmann, 1974). This comparison may assist future conservationists in their efforts to …

Bioinformatics and Next Generation Sequencing: Applications of Arthropod Genomes
… spider mites with three completely different feeding behaviors, we uncovered genomic signature variations and indicative of pest adaptations; (2) we sequenced, assembled and annotated five Brevipalpus flat mite genomes and their corresponding endosymbiont Cardinium genomes. Comparative …

Quantifying Resource Use Among Insectivorous Bat Species with Overlapping Distributions
… pollen, and even seeds and foliage. However, the feeding ecology of these organisms is not well understood. Most bat species in North America rely on the same method of foraging and locomotion. The geographical range and habitats of these bats also commonly overlap. Bat feeding ecology studies …

Parental Perspective and Feeding Practices Effects on Food Neophobia in Elementary-Age School Children
<p>The Food neophobia (FN) behaviors in children are developed during childhood and can be influenced by parental FN and feeding behaviors. The objective of this study was to evaluate the relationship between FN and fruit and vegetable neophobia (FVN) among parents, the parents-reports on child's …

Lateral hypothalamic control of motivated behaviors through the midbrain dopamine system
… involved in processing reward and the control of feeding behaviors. We continue work in this area by identifying the functional connectivity between these two regions, providing evidence that LH neurons projecting to the VTA encode conditioned responses, while LH neurons innervated by the VTA …

Cross-scale assessment of environmental variation on RABV reservoir Desmodus rotundus
… Desmodus rotundus is a sanguivorous (blood-feeding) species that can easily transmit RABV to their prey during normal feeding behaviors, thereby acting as a wildlife reservoir and known host for the virus. Previous research has found that vampire bat-transmitted RABV has increased in …

Effects of Fluid Properties on the Dynamics of Mosquitoes' Ingestion Pumps
This thesis explores the feeding structures of insects, which have evolved over millennia to utilize a variety of dietary sources. It examines the mouthparts of insects feeding on plants, other bugs, or vertebrate blood, analyzing how these structures influence or limit their diet. Focusing …
