Analysis Of Temperature And Salinity Effects On Growth And Mortality Of Oysters (Crassostrea Virginica) In Louisiana, Troy Sehlinger

University of New Orleans Theses and Dissertations

Salinity (S) and temperature (T) control every facet of the eastern oyster (Crassostrea virginica) life cycle, principally reproduction, development, growth, and mortality. Previous studies conducted in in the Breton Sound (BR) and Barataria (BA) estuaries have reported differences in growth and mortality rates between the basins. In the present study, environmental conditions were synchronized to compare growth and mortality rates between basins at similar combinations of T and S. Results indicate that when T and S are the same (synchronized), seasonal oyster growth and mortality rates differ between BR and BA. Seasonal analyses revealed that as salinities increased in both ...

A Framework For Assessing Natural Lands And Finding Common Ground In The Bear River Range, Scott Mccomb

All Graduate Plan B and other Reports

Forests, wetlands, grasslands, lakes and deserts make up the natural lands that humans and nature rely on. In the Bear River Range, these lands are becoming smaller and more disconnected due to residential and commercial development, agriculture, energy production and transportation corridors. In addition, natural lands are owned and managed by a variety of groups representing different values, priorities and traditions. For large-scale conservation to be successful, it needs to incorporate multiple priorities. The purpose of this study was to provide a process for identifying the remaining network of natural lands within the Bear River Range that indicate high ecological ...

The Perception Of Utah Division Of Wildlife Resource’S Law Enforcement By Local, County And Municipal Law Enforcement Agencies, Wyatt Bubak

All Graduate Plan B and other Reports

Like most states throughout the nation, Utah’s population has continually grown since settlement. In 2014 Utah’s population was estimated at 2.95 million and between 2015-2016 Utah had the highest percentage growth rate of any state in the nation. This profound amount of growth can be attributed to many factors that are unique to Utah; two of which are the aesthetic and recreational opportunities available to Utah residents.

Due to population growth and urban sprawl, areas commonly patrolled by Utah Division of Wildlife Resources (UDWR) conservation officers are now located closer to urban populations. Previously rural or backcountry ...

A Comparison Of Vnir And Mir Spectroscopy For Predicting Various Soil Properties, Joshua R. Gates

Dissertations & Theses in Natural Resources

Soil plays an important role in our daily lives, namely producing food, cleaning water and storing carbon. The ability to rapidly and cost-effectively quantify the various components of soils can help us understand and better manage this important resource. This study aims to compare the ability of visible near-infrared (VNIR) spectroscopy and mid-infrared (MIR) spectroscopy to quickly and accurately predict various important soil properties (electrical conductivity, soil pH, cation exchange capacity, exchangeable cations, phosphorus, carbon, beta-glucosidase enzyme activity and nitrogen). Prediction models were developed using partial least squares regression (PLSR) techniques. Three different calibration sampling methods were tested along with ...

Boundary Spanners And Trust Development Between Stakeholders In Integrated Water Resource Management: A Mixed Methods Study, Jodi L. Delozier

Dissertations & Theses in Natural Resources

Natural resource issues are inherently complex, even more so are those that involve the management of water. Because watersheds tend to cross multiple jurisdictional and geographical boundaries, a diverse set of stakeholders are needed to develop appropriate and sustainable management policy. This research sheds light on the importance of boundary spanners assisting in the development of trust between stakeholders in integrated water resource management (IWRM). Previous literature has explored the advantages to boundary spanning leadership in business practice, emergency management, university and community management as well as fish and wildlife management, but has failed to address the area of integrated ...

Why Do They Do That? Understanding Factors Influencing Visitor Spatial Behavior In Parks And Protected Areas, Abigail M. Sisneros-Kidd

All Graduate Theses and Dissertations

Visitors to parks and protected areas within the United States and worldwide often visit these areas with a particular destination in mind, such as seeing Old Faithful erupt in Yellowstone National Park or standing on the rim of the Grand Canyon in Grand Canyon National Park. These visitor use destinations, and the pathways leading to them, such as trails and roadways, see high levels of use, and as a result, impacts to soil, vegetation, air, water, soundscapes, and night skies that result from this use. The field of recreation ecology studies these impacts to park and protected area resources resulting ...

Improving The Calibration Of Silicon Photodiode Pyranometers, Elizabeth Walter-Shea, Kenneth Hubbard, Mark A. Mesarch, Glen Roebke

Papers in Natural Resources

Reliable measurements of global irradiance are essential for research and practical applications. Silicon photodiode pyranometers (SiPs) offer low-cost sensors to measure direct and diffuse irradiance despite their non-uniform spectral response over the 300–1000 nm spectral range. In this study, non-adjusted linear and adjusted calibrations were applied at different times of the year to determine sources of estimated errors in global irradiance due to the two calibration approaches, calibration time, and sensor age. 16 SiPs, along with two standards, measured incident global irradiance over a 5-year period under a range of sky conditions. Sensors performed best in the months in ...

Analysis Of Gravity Recovery And Climate Experiment (Grace) Satellite-Derived Data As A Groundwater And Drought Monitoring Tool, Anthony James Mucia

Dissertations & Theses in Natural Resources

This research compares Gravity Recovery and Climate Experiment (GRACE) groundwater storage (GWS) and root zone soil moisture (RZSM) percentiles to measured data, other drought indicators (DIs) and indices, and stakeholder observations for the purpose of assessing the feasibility and usefulness of these products to detect drought conditions. GRACE percentiles were directly compared to historic groundwater percentiles at 89 Nebraska well locations. Spatial time-series correlations over CONUS were performed between GRACE GWS and RZSM and the U.S. Drought Monitor (USDM), Standardized Precipitation Index (SPI), and soil moisture parameters from several North American Land Data Assimilation System (NLDAS) models. A survey ...

An Evaluation Of Deterrent Methods Utilized To Prevent Crop Raiding By African Elephants (Loxodonta Africana) In The Kasigau Wildlife Corridor, Kenya, Rebecca Lynn Von Hagen

Masters Theses & Specialist Projects

Escalating human elephant conflict (HEC) continues to be a contributing factor

towards elephant decline, and crop raiding is the most common form of negative

human-elephant interactions. For communities that cannot reverse or prevent crop

raiding, it is necessary to contain HEC events through deterrent measures. Few

deterrent measures exist that combine practicality and affordability while also

preventing habituation by elephants. This project focused on comparing the efficacy of

deterrent methods to assess which was the most successful at preventing elephants

from entering crops in the farming community of Sasenyi, Kenya. In this paired-control

study, four deterrent methods were evaluated: acacia ...

This paper explores the practice of restoration ecology to assess its ability to help people adapt to a future with water challenges. Research revealed that restoration ecology can be used to better prepare people for a future with water shortages. By adopting the Society for Ecological Restoration Australasia’s National Restoration Standards, the efficiency ...

Desalination Concentrate Disposal: Ecological Effects And Sustainable Solutions, Ryan Hanley

Global Honors Theses

Freshwater availability is a growing global concern, and desalination is often presented as the solution, but from this important technology comes issues of toxic waste. Ecosystems are delicate areas that contain species adapted to that specific location, and any chemical or physical changes can disrupt the fitness of species. The concentrate byproduct waste from desalination plants is toxic to species if the concentrate is not compatible with the receiving water body. A critical review of scientific articles, industry-leading books, conversations with industry experts, and information from the American Membrane Technology Association conference was used to analyze the current knowledge. Species ...

An Opportunity To End The Timber Wars: How Collaboration In Southeast Alaska Has Helped To Dissipate Conflict, Diana K. Portner

Humboldt Journal of Social Relations

Forest management in the Tongass National Forest has been a topic of controversy for decades, due to the result of intense timber extraction in the mid-twentieth century. In recent years, collaborative approaches to management, beginning with a federally chartered advisory committee, have offered opportunities to overcome the seemingly intractable conflict. While a new culture of collaboration is emerging in Southeast Alaska, the region still faces challenges associated with the implementation of these approaches. This commentary explores the history of the conflict, factors that contributed to the success of collaborative approaches to land management in the region, and continued challenges that ...

Spatial And Temporal Analysis Of Island Morphology In Lower Pool 18 Of The Mississippi River, Marissa C. Iverson

Celebration of Learning

The Upper Mississippi River System has a significant trend in island loss due to river engineering structures. However, Lower Pool 18 is observed as a counterexample to the island loss pattern with its island development near Lock and Dam 18 during the past 80 years. This research is modeled after a study done in Lower Pool 6 of the Upper Mississippi River where an island development was found to contradict the island loss prevalence. The Lower Pool 18 research’s goal is to map, describe, and explain spatial patterns of islands growth, persistence and loss. Historical maps and aerial photographs ...

Functions Of Ecosystems: Stream Metabolism As An Efficient And Effective Means To Gage The Health And Understand The Interworking Of Urban Streams In A Watershed Of Rock Island, Il, Ryan Johnson, Dr. Kevin Geedey

Celebration of Learning

Stream metabolism is a critical functional measure of stream health that integrates physical parameters like slope and discharge, with ecosystem functions like photosynthesis and respiration. Stream metabolism is widely studied; however, urban stream metabolism remains poorly understood. Stream metabolism was measured for five streams ranging from 1^st to 5^th orders from October 11^th to October 18^th 2017 and four streams ranging from 1^st to 4^th order from October 22^nd to 25^th 2017 located within an approximately 9.3 square kilometer watershed of Rock Island, IL that has an urban to suburban type ...
