Genetic Drift Simulation, Imsa Biology Team

Evolution

Genetic drift can be defined as a random fluctuation in gene frequency. More specifically, it tells us that different alleles may increase or decrease in a population in proportion to one another over time, just by chance, rather than due to any fitness advantage.

An Irrigation Canal As A Lotic Mesocosm: Examining The Relationship Between Macroinvertebrate Benthos And Drift, Peter Koetsier, Luana M. M. Mccauley

Biology Faculty Publications and Presentations

We explored the notion that small canals could be good experimental proxies of streams by documenting physiochemical parameters and macroinvertebrate community development in an aridland irrigation canal. Further, we tested the production-compensation hypothesis between benthic invertebrates and invertebrates in the water column (drift). If the hypothesis held, invertebrates in the drift would be low until the benthic carrying capacity was reached; then organisms in the drift would increase as individuals avoided overcrowded conditions in the substrate. In a small, naturalized freshwater canal, we sampled macroinvertebrates in the substrate and those in the drift once every 2 weeks over 170 days …

Evidence Of Evolution 3: Evolutionary Evidence And Inferences Lab: A Discussion Guide, Imsa Biology Team

This lab activity was designed to provide you with opportunities to make inferences and draw conclusions about evolution and the common ancestry of various animals based on their anatomical characteristics and comparative anatomy. You will be given tasks to accomplish or questions to answer at each of 11 stations. In order to do this successfully, you must make careful observations of the specimens on display.

An Insight Into The Functional Role Of Thioredoxin Reductase, A Selenoprotein, In Maintaining Normal Native Microbiota In The Gulf Coast Tick (Ambylomma Maculatum), Khemraj Budachetri, Shahid Karim

Faculty Publications

Tick selenoproteins have been associated with antioxidant activity in ticks. Thioredoxin reductase (TrxR), also a selenoprotein, belongs to the pyridine nucleotide‐disulphide oxidoreductase family of proteins and is an important antioxidant. Molecular interactions between native microbiota and tick hosts have barely been investigated to date. In this study, we determined the functional role of TrxR in tick feeding and in maintenance of the native microbial community. TrxR transcript levels remained high and microbial load was reduced throughout tick attachment to the vertebrate host. RNA interference (RNAi) showed that depletion of TrxR activity did not interfere with tick haematophagy or phenotype but …

Repeated Trait Evolution Driven By Divergent Natural Selection At Early And Late Stages Of Speciation, Spencer J. Ingley

Theses and Dissertations

Speciation – the process by which new species arise – is of fundamental importance in the biological sciences. The means by which new species arise, and the relationship among living species, has been a topic that has captivated both lay and scientific observers for centuries. In recent years, the study of speciation has enjoyed increased attention, resulting in significant advances in our understanding of how species form. Although our understanding of the processes that contribute to speciation has increased dramatically in recent years, our knowledge of how reproductive barriers accumulate as speciation proceeds is still limited. Thus, studies that evaluate …

Wildfire Disturbance And Productivity As Drivers Of Plant Species Diversity Across Spatial Scales, Laura A. Burkle, Jonathan A. Myers, R Travis Belote

Biology Faculty Research

Wildfires influence many temperate terrestrial ecosystems worldwide. Historical environmental heterogeneity created by wildfires has been altered by human activities and will be impacted by future climate change. Our ability to predict the impact of wildfire-created heterogeneity on biodiversity is limited because few studies have investigated variation in community composition (beta-diversity) in response to fire. Wildfires may influence beta-diversity through several ecological mechanisms. First, high-severity fires may decrease beta-diversity by homogenizing species composition when they create landscapes dominated by disturbance-tolerant or rapidly colonizing species. In contrast, mixed-severity fires may increase beta-diversity by creating mosaic landscapes containing habitats that support species with …

Parameter Estimation For Gene Regulatory Networks From Microarray Data: Cold Shock Response In Saccharomyces Cerevisiae, Kam D. Dahlquist, Ben G. Fitzpatrick, Erika T. Camacho, Stephanie D. Entzminger, Nathan C. Wanner

Biology Faculty Works

We investigated the dynamics of a gene regulatory network controlling the cold shock response in budding yeast, Saccharomyces cerevisiae. The medium-scale network, derived from published genome-wide location data, consists of 21 transcription factors that regulate one another through 31 directed edges. The expression levels of the individual transcription factors were modeled using mass balance ordinary differential equations with a sigmoidal production function. Each equation includes a production rate, a degradation rate, weights that denote the magnitude and type of influence of the connected transcription factors (activation or repression), and a threshold of expression. The inverse problem of determining model …

Temporal Variability And Cooperative Breeding: Testing The Bet-Hedging Hypothesis In The Acorn Woodpecker, Walter D. Koenig, Eric L. Walters

Biological Sciences Faculty Publications

Cooperative breeding is generally considered an adaptation to ecological constraints on dispersal and independent breeding, usually due to limited breeding opportunities. Although benefits of cooperative breeding are typically thought of in terms of increased mean reproductive success, it has recently been proposed that this phenomenonmay be a bet-hedging strategy that reduces variance in reproductive success (fecundity variance) inpopulations living inhighly variable environments. We tested this hypothesis using long-term data on the polygynandrous acorn woodpecker (Melanerpes formicivorus). In general, fecundity variance decreased with increasing sociality, at least when controlling for annual variation in ecological conditions. Nonetheless, decreased fecundity variance …

Viral Vector-Based Improvement Of Optic Nerve Regeneration: Characterization Of Individual Axons' Growth Patterns And Synaptogenesis In A Visual Target, Benjamin J. Yungher, Xueting Luo, Yadira Salgueiro, Murray G. Blackmore

Biological Sciences Faculty Research and Publications

Lack of axon growth ability in the central nervous system poses a major barrier to achieving functional connectivity after injury. Thus, a non-transgenic regenerative approach to reinnervating targets has important implications in clinical and research settings. Previous studies using knockout (KO) mice have demonstrated long distance axon regeneration. Using an optic nerve injury model, here we evaluate the efficacy of viral, RNAi and pharmacological approaches that target the PTEN and STAT3 pathways to improve long distance axon regeneration in wild type (WT) mice. Our data show that adeno-associated virus (AAV) expressing short hairpin RNA (shRNA) against PTEN (shPTEN) enhances retinal …
