The Future Of Biodiversity Assessment: Using Environmental Dna And Next-Generation Sequencing To Characterize Biological Communities In The Central Highlands Of Arizona, Courtney Turner-Rathbone

Undergraduate Research Symposium - Prescott

Historically ecological surveys require significant man hours in the field, utilizing methods which can stress species being observed. In using environmental DNA (eDNA) gathered from air, soil, and water, traditional methods may be supplemented or reduced in order to more efficiently utilize funding and reduce or eliminate stress on surveyed species. Water was collected in replicates using aseptic technique from two different sites, 60 miles apart, along the Verde River. Samples were vacuum filtered within 24 hours through 0.45 μm cellulose nitrate (CN) filters to collect eDNA. DNA extraction from the filters was performed. The polymerase chain reaction (PCR) was …

Genetic Differentiation Between Two Species Of Buckwheat (Eriogonum), Paul G. Wolf, Jenessa B. Lemon

Browse all Datasets

Discovering the extent of genetic differentiation between closely related taxa facilitates decisions regarding species protection under the Endangered Species Act. Here, we analyze genotype data to explore the relatedness of two buckwheat species: Eriogonum soredium Reveal- a narrow endemic under consideration for protection, and a widespread close relative, Eriogonum shockleyi S. Watson. Eriogonum soredium grows only on Ordovician limestone outcroppings in west central Utah, whereas the range of E. shockleyi is broad, spanning the western United States from Colorado to California, and Idaho to Arizona. Eriogonum shockleyi is suspected of hybridizing with other buckwheats throughout this range. We detected higher …

Shoreline Characterization For Northern Indian River Lagoon And Mosquito Lagoon, Melinda J. Donnelly, Linda Walters, Michelle Shaffer

CEELAB Research Data

The purpose of this project was to evaluate the current conditions of estuarine shorelines in Mosquito Lagoon and northern Indian River. The shoreline assessment is the first phase in the development of a shoreline restoration suitability model for the northernmost section of the Indian River Lagoon system, in order to better conserve and restore shorelines and promote sustainable use of natural resources. The shoreline survey methodology was developed by St. Johns River Water Management for northeastern Florida and was adapted for applications in Brevard and Volusia Counties. Between November 2017 through June 2018, shoreline evaluations were completed at transects located …

What Should Go In A Wildlife Professional’S Geospatial Toolbox? (Response Data), William Bean, Ryan C. Baumbusch, Brooke Berger, Matthew Delheimer, Lee J. Hecker, Matthew Lau, Megan C. Milligan

Research Data Sets

Geospatial tools have become a critical component to most wildlife studies and management questions. With a diversity of approaches available, current and future wildlife professionals deserve guidance on the most important tools to answer these questions. Younger professionals may be expected to know a separate set of skills from those required further on in their career. We conducted an online survey and a year-long search of job advertisements to identify the most important geospatial approaches, techniques, programs, and ancillary skills for wildlife professionals. We provide the results of these 2 efforts so that wildlife professionals interested in geospatial tools can …

Seasonal Dimorphism In Gastropod Hatchling Size: What Can We Learn From Egg Mass Morphology And Deposition Site Conditions?, Lily A. Harrison

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Egg size is one of the most important features of marine invertebrate reproduction because it provides insight into developmental patterns, offspring size, and adult investment per offspring. Intraspecific variation in egg size and the resulting hatchling size may depend on many factors including environmental and maternal conditions and geographic location. Therefore, both the season in which eggs are laid and the spatial heterogeneity of deposition sites may influence egg size and hatchling size. Natica chemnitzii deposits egg masses on sandy beaches along the coast of the Bay of Panama. During the wet (non-upwelling) season hatchling size is unimodal. However, monthly …
