Beyond DNA Compaction: An Emerging View of the Diverse Functions of Drosophila Sperm Nuclear Basic Proteins
While sperm of different animals exhibit morphologically distinct features, the overall themes of sperm nuclei are surprisingly similar among species. Sperm nuclei are extremely condensed and transcriptionally inert, and ... -
Comparison of hair and DNA-based approaches in dietary analysis of free-ranging wolves (Canis lupus) in Alberta, Canada
Dietary information of free-ranging animals is essential for understanding their ecology, conservation and management. Carnivore diet is most frequently estimated using morphological analysis of prey remains found in scats. ... -
Developing and applying transient expression systems to identify and understand gene regulatory elements in plants
In this dissertation, I develop transient expression systems to enable massively parallel reporter assays (MPRAs) in crop models. I apply these transient assay systems to identify, characterize and design plant gene ... -
Diversification and Local Adaptation in Western Fence Lizards, Sceloporus occidentalis
I am fascinated by intraspecific variation–by both its sources and its potential implications for how organisms interact with their environments. The importance of intraspecific variation for predicting species responses ... -
Exploring Drivers of Gene Flow in Jaguars and Pumas in Southern Mexico via Molecular Scatology and Eco-Evo Simulations
The profound fragmentation and degradation of Neotropical forests over the past 50-100 years poses a significant threat to the wildlife populations in Mesoamerica. Neotropical large carnivores, jaguars (Panthera onca) and ... -
Exploring snake evolution through time and space
Lineages diversify as they disperse through time and space, which provides ever increasing complexity to be considered in investigations at different taxonomic levels. Population genetic and phylogenetic signal sometimes ... -
Exploring the Mechanisms of Regeneration in Ptychodera flava
Hemichordates are marine acorn worms and a sister group to the echinoderms. Acorn worms share numerous developmental features with the chordates that the echinoderms do not share, suggesting that the common ancestor of the ... -
Floral volatiles in Mimulus: chemical ecology, insect olfaction, genetics, and reproductive isolation
Floral diversity is immense, with more than 250,000 species of angiosperms known. The number of phylogenetically diverse floral species that share common characteristics implies a background pattern of selection acting on ... -
From Genetics to Behavior, the Dynamics and Mechanisms of Adult Neurogenesis in a Sensorimotor Circuit
The most defining attribute of the nervous system is that it shows extensive plasticity of structure and function that allows animals to adjust their behavior, physiology, and morphology to changes in their environment. ... -
Gene flow and models of avian speciation in tropical mountains
Eight decades after the modern synthesis, the role of gene flow in speciation remains contentious. Because gene flow is a homogenizing force and sister species frequently occur in allopatry, geographic isolation was assumed ... -
Linking protein function to complex traits
In this dissertation, I aim to establish the utility of linking large-scale protein mutagenesis to complex trait selection in order to better understand how subtle alterations to protein function lead to shifts in trait ... -
Microbial evolution in changing environments
{\it Chapter 1.} Compensatory mutations play a critical role in the evolution of drug resistance in microorganisms. Most directly, they serve to alleviate the fitness cost commonly associated with initial drug resistance ... -
Molecular regulations and lineage tracing in early Mouse embryogenesis
(2013-04-17)This dissertation research aims to understand the regulations and developmental patterns of mouse early embryogenesis, in order to gain comprehensive knowledge in human early development to further the ultimate goal of ... -
Seasonal Migration, Gene Flow, and Speciation in North American Birds
Around 20% of bird species migrate annually between distinct breeding and wintering ranges and many sedentary populations shift cyclically within a single range in response to varying climates and food availability. Migration ... -
Species from feces: Decoding the secrets of genetic resilience, microbiome shift and niche partitioning from droppings
Effective species recovery plans rely on adequate scientific data, being tailored to the species’ natural history and keeping up with rapid socioeconomic changes. My dissertation focuses on two great conservation success ... -
Using yeast to trace a history of expanding auxin signals
Auxin is a hormone that plays essential roles in almost all growth and developmental processes across allplants. The way cells interpret responses to auxin is regulated by the auxin signal transduction pathway - a tangled ...
