Chronic heat stress resistance in Caenorhabditis remanei

Claridge, Sally Elizabeth

Organisms are subjected to a wide range of stressful conditions throughout their lifetime. Environmental stress can drive a population to adapt to novel conditions by yielding selective advantages to subsets of the population. ...
Circuit and Behavioral Analysis of Klinotaxis in Caenorhabditis elegans

McCormick, Kathryn (University of Oregon, 2013-10-10)

The nervous system is a complex organ that functions in most metazoans to sense and respond to a constantly changing world. How the nervous system does this is a major focus of systems-level neuroscience. This dissertation ...
Differential lifespan effects due to mating in two strains of Caenorhabditis elegans

Lancaster, Ruben; Kasimatis, Katja

Mating is vital for sexually reproducing species, yet the ideal mating strategy for males and females can differ. The ensuing conflict between the sexes – namely sexual conflict – results in a decrease in population level ...
Dissecting the Genetic Architecture of Complex Traits in the Nematode Caenorhabditis remanei

O'Connor, Christine (University of Oregon, 2018-09-06)

A central problem in evolutionary quantitative genetics has been to attempt to dissect the genetic basis of complex traits. A variety of inferential methods have been developed to probe this issue. Here, I use experimental ...
Economic Decision Making and Neural Correlates of Subjective Value in the Nematode Worm, Caenorhabditis elegans

Katzen, Abraham (University of Oregon, 2018-04-10)

Decision making is pervasive in nature. Organisms from across the phylogenetic spectrum take in information from the external world and pursue courses of action in an attempt to maximize their evolutionary fitness. When ...
Holocene Legacy: Evolution of Thermal Tolerance and Bloodfeeding in the Pitcher-Plant Mosquito, Wyeomyia smithii

Gerritsen, Alida (University of Oregon, 2014-09-29)

The legacy of historical biogeography impacts many organisms and results in a wide range of character variation over a latitudinal gradient. The pitcher-plant mosquito Wyeomyia smithii is one such organism that demonstrates ...
The Neurodevelopmental and Genetic Basis to Natural Variation in Thermal Preference Behavior in Caenorhabditis elegans

Gaertner, Bryn (University of Oregon, 2012)

In a heterogeneous environment where temperature influences fitness, individuals must navigate to a thermal optimum to maximize reproductive output and minimize physiological stress. However, the optimal temperature varies ...
Overcoming the Current Limitations of Next-Generation Sequencing with New Methods for Local Assembly of Genomes and High-Specificity Rare Mutation Detection

Preston, Jessica (University of Oregon, 2016-02-23)

The relatively low cost of Next-Generation Sequencing (NGS) has enabled researchers to generate large amounts of sequencing data in order to identify disease-causing mutations and to assemble simple genomes. However, NGS ...
SYNERGIZING GENETIC ENGINEERING AND EVOLUTIONARY BIOLOGY: ANIMAL-BASED LINEAGE TRACKING TO STUDY ADAPTIVE MUTATIONS

Stevenson, Zachary (University of Oregon, 2024-03-25)

The fitness effects of new mutations are one of the central drivers of evolutionary change. Mutation is the ultimate source of novel genetic diversity, yet only a small fraction of new mutations provides an adaptive ...
The Genetic Basis of Natural Variation in the Response to Adult Starvation in Caenorhabditis elegans

Archer, Heather (University of Oregon, 2019-09-18)

Caenorhabditis elegans typically feeds on rotting fruit and plant material in a fluctuating natural habitat, a boom-and-bust lifestyle. Moreover, stage specific developmental responses to low food concentration suggest ...
The Impacts of Environmental Perturbations on Life History Trajectories in Caenorhabditis elegans.

de Verteuil Yeboah, Precious (University of Oregon, 2020-09-24)

Environmental fluctuations are ubiquitous in nature and can serve to drive phenotypic differences among individuals in an environment-specific manner, a phenomenon known as phenotypic plasticity. Phenotypic plasticity can ...
The Influence of Sexual Selection and Sexual Conflict on the Evolution of Post-Insemination Dynamics

Kasimatis, Katja (University of Oregon, 2019-09-18)

Sexual reproduction is a fundamental process that structures populations and modulates interactions between species. The reproductive process is shaped by selection acting on the variance in mating success. Additionally, ...
