THE ALAN SHEPARD (SHEP) GENE REGULATES NEURONAL REMODELING DURING METAMORPHOSIS
(2014)
Peptidergic neurons are a group of neuronal cells that synthesize and secrete peptides to regulate a variety of biological processes. To identify genes controlling the development and function of peptidergic neurons, our ...
TREES AS ECOLOGICAL TEMPLATES FOR TROPICAL LITTER ARTHROPOD COMMUNITIES
(2012)
My dissertation spans five chapters on diverse topics on the ecology and taxonomy of ants in tropical regions. In Chapter 1, I explored if tree species identity explained litter arthropod biodiversity. In Chapter 2, I ...
The Spatial Distribution of, and Upland Impacts on, Playa Wetland Invertebrates
(2015)
Playa wetlands are a type of temporary wetland that are numerous in the Great Plains of the United States. Playa wetlands offer a unique habitat within semiarid grassland ecosystems. My research on the invertebrates of ...
Aversive learning effect on odor coding in rat's piriform cortex
(2011)
Olfaction, a sense for detecting and discriminating chemical molecules in the environment, is critical for animal survival, reproduction and other adaptive behaviors. The olfactory system is organized in three major stations ...
The Evolution Of Reproductive Isolation In A Temporally Complex Passerine Hybrid Zone
(2014)
Understanding the relative importance of reproductive isolating barriers between populations allows us learn what processes are most prevalent in causing speciation. Hybrid zones, where distinguishable populations interbreed, ...
AN ENHANCER-TRAP AND SPLICE-TRAP SCREEN FOR REGULATORS OF ENDOCRINE FUNCTIONS IN THE CENTRAL NERVOUS SYSTEM AND THE EPITRACHEAL GLAND OF DROSOPHILA MELANOGASTER
(2010)
Peptide hormones play important roles in a wide variety of biological processes, such as learning and memory, body weight homeostasis, circadian rhythms, and addiction. In Drosophila, over 20 peptide hormones are produced ...
FROM COOPERATION TO COMPETITION: HOW MICROBES AND INVERTEBRATES INTERACT IN A TROPICAL FOREST
(2018-05)
Microbes and invertebrates are “the little things that run the world” (Wilson 1987, Moreau 2017), but the intricacies of how these organisms impact our environment remains underexplored. Here I investigate how microbes and ...
Sexual signaling in conflicts and their resolutions in odonates
(2014-12)
Nature abounds with conflicts and searching for the best solution to conflicts is of interest to all animals. Among various means to resolve conflicts, signaling may be superior because it can potentially settle conflicts ...
Hierarchical controls on the impact of consumer stoichiometric regulation: From species traits to ecosystem level consequences
(2013-12)
As natural ecosystems become increasingly changed due to habitat alteration, species loss, introduction of non-native species, and climate change, understanding the functional significance of communities to ecosystem ...
The ecological importance of ant colony size
(2010)
Despite the rich diversity of life, all organisms are unified by the conserved biochemical pathways that drive metabolism and govern the rate at which resources are processed and used to perform biological work. Metabolic ...
