Detecting Multiple Paternity In Mule Deer: Variations Among Populations And The Ecological Significance, Madeline K. Martin, Sydney Lamb, Anna K. Monson, Paul B. Frandsen, Brock R. Mcmillan
Detecting Multiple Paternity In Mule Deer: Variations Among Populations And The Ecological Significance, Madeline K. Martin, Sydney Lamb, Anna K. Monson, Paul B. Frandsen, Brock R. Mcmillan
Library/Life Sciences Undergraduate Poster Competition 2023
We are interested in detecting the absence or rate of multiple paternity within mule deer populations (Odocoileus hemionus) due to 1) their unique breeding system where males mate-guard females from other males[2], and 2) the highly skewed male-biased sex ratios in populations as a result of harvest management. Comparing the rate of multiple paternity to sex ratio will suggest if harvest management is influencing long-term population genetics.

Identifying Deep Brain Photoreceptors In The Larval Zebrafish Optic Tectum, Emalie A. Christensen, Allison G. Pickens, Sarah Y. Jarrett, Maurice Hunt, Arminda Suli
Library/Life Sciences Undergraduate Poster Competition 2023
Deep brain photoreceptors (DBPs) are light sensing neurons present in mammals and non-mammalian vertebrates. In non-mammalian vertebrates, studies have shown DBP involvement in various time and light dependent behaviors including circadian rhythm, phototaxis, and seasonal reproduction. In adult teleosts, DBPs are present throughout the brain, including the optic tectum (OT). While their approximate location in teleosts is known, DBP’s function is relatively unknown. In this study, we focused on DBPs present in the larval zebrafish OT, a multilaminated midbrain structure responsible for multisensory integration. Single-cell RNA sequencing of the larval zebrafish OT showed the presence of several opsins. We focused …

The structural organization of DNA in eukaryotic cells is greatly implicated in the regulation of gene expression and thus cellular properties and behavior. At the most fundamental unit of this organization, ~147 bp of DNA wraps 1.7 times around a histone octamer core, forming a collective unit called the nucleosome. The positioning and occupancy of these nucleosomes around the promoter elements of genes is known to be a strong regulator of transcription in eukaryotic nuclei, and post-translational modifications (PTM’s) to the protruding N-terminal tails of histone proteins are known to influence chromatin structure and thus gene expression; however, relatively little …

A wonderful blend of physiology, nutrition, biochemistry, genetics, biology, evolution, chemistry--what we all need to know as informed citizens. A basic knowledge of the life sciences and how our bodies work--to promote our own good health, especially as we're bombarded with misleading advertisements, soundbites, and the like. DNA fingerprinting, calorie requirements, dietary advice, genetic engineering (including gene editing with CRISPR cas9)--all in an easy-to understand book.
Introduction And Evaluation Of 10 Hybrid Quinoa X Pitseed Goosefoot Lines In Central Malawi, Carter D. Allred, Mike Banda, Eric Jellen, Moses F.A. Maliro
Introduction And Evaluation Of 10 Hybrid Quinoa X Pitseed Goosefoot Lines In Central Malawi, Carter D. Allred, Mike Banda, Eric Jellen, Moses F.A. Maliro
Library/Life Sciences Undergraduate Poster Competition 2020
Protein deficiency is common amongst subsistence farmers in much of the developing world. It has been estimated, for example, that over one third of residents of rural Malawi are protein deficient. Adding to this problem in Malawi is the fact that there is only one brief rainy season, during which all crops are grown. Other countries with as dry a climate in the region have low population density, which allows them to reap more from their annual maize harvest. Meanwhile, countries in the region with similarly high population density as Malawi are able to grow higher value crops because of …
Floral Traits Underlying Evolution In Gilia Yorkii, Joseph Detemple, Veronica Mosquera, Clinton Whipple
Floral Traits Underlying Evolution In Gilia Yorkii, Joseph Detemple, Veronica Mosquera, Clinton Whipple
Library/Life Sciences Undergraduate Poster Competition 2020
Gilia yorkii and Gilia capitata are two closely related species that have remarkably different inflorescence and floral structures. In this project we are seeking to find specific floral traits that differentiate the different species. These two species are ideal for this study because they produce a fertile hybrid in which elements of the two different phenotypes can be observed.
The Fight Against Overweight And Obesity Among Adolescents, Jordan Reichel
The Fight Against Overweight And Obesity Among Adolescents, Jordan Reichel
All Student-Created Educational Resources
The purpose of this handout is to use evidence-based research to educate the adolescents population about the growing problem of overweight and obesity among youth in this age group. This handout describes the criteria for being considered overweight or obese during adolescence. Possible risk factors for adolescent overweight and obesity are identified. The handout discusses the burden of disease and the potential consequences associated with being overweight or obese as an adolescent. Behavior modification strategies for preventing or treating overweight and obesity in adolescent’s are also described.

The purpose of this study was to evaluate the use of semi-structured interviews as an outcome measure in a clinical trial for children with fragile X syndrome (FXS) ages 2-6. This qualitative approach was used to analyze twenty-five interviews of parents with children in a double-blind medication trial - sertraline or placebo. The aim was to assess occupational improvements in their child that may not have been detected with the use quantitative outcome measures alone. Results showed greater improvements in the sertraline group in areas of behavior, social participation, sensory-related behaviors, receptive language, education, family impact and therapeutic strategies. Our …

Ewe And Wether Trials - Tools For Benchmarking Your Sheep Genetics, Lock Butler
Ewe And Wether Trials - Tools For Benchmarking Your Sheep Genetics, Lock Butler
Bulletins 4000 -
Research and sheep productivity trial results demonstrate a huge variability in genetic productivity between flocks. For example a range of up to 2 kg clean fleece weight, 5 microns, 55 percentage points in lambing percentage and 20 kg live weight, can lead to big differences in gross margin between flocks.
There is an opportunity for genetic improvement, depending on your current ram source or sires performance. For example, Western Australian (WA) Wether Trial results suggest half the WA flocks could improve clean fleece weight per head by half a kilogram or more. The trial results suggest that this could occur …
