Double-crested Cormorant (Phalacrocorax auritus) numbers have increased in North America, and con- comitantly cormorants appear to be expanding their nesting range in the southeastern United States.
Because colonial nesting waterbirds can impact water quality, soil chemistry and subsequent vegetation succession patterns, our goal was to assess the extent to which cormorant breeding colonies are influencing the biotic and abiotic attributes of forested islands in the southeastern United States. Our objectives were to (1) compare water quality characteristics in near-shore surface waters around forested islands with and without nesting cormorants during the peak-nesting/fledgling period and post-fledgling period, (2) measure soil ...


Fire And Fuels: Vegetation Change Over Time In The Zuni Mountains, New Mexico, Luke Wylie 2016 University of Southern Mississippi

Fire And Fuels: Vegetation Change Over Time In The Zuni Mountains, New Mexico, Luke Wylie

Master's Theses

The Zuni Mountains are a region that has been dramatically changed by human interference. Anthropogenically, fire suppression practices have allowed a buildup of fuels and caused a change in the fire-adapted ponderosa pine ecosystem such that the new ecosystem now incorporates many fire-intolerant species. As a result, the low-severity fires that the ecosystem once depended on to regenerate the forest are much reduced, and these low-severity fires are now replaced by crown-level infernos that threaten the forest and nearby towns. In order to combat these effects, land managers are implementing fuel reduction practices and are striving to better understand the ...


Temperature Variation In Nest Boxes In Eastern Australia, Ross L. Goldingay 2016 Southern Cross University

Temperature Variation In Nest Boxes In Eastern Australia, Ross L. Goldingay

Associate Professor Ross L Goldingay

Nest boxes are frequently installed in Australia to provide shelter sites for arboreal mammals. Little is known about the temperatures that may be experienced inside nest boxes or the factors that may influence those temperatures. I established paired nest boxes on the south-east and north-west sides of trees at two locations in south-east Queensland to investigate the influence of nest box aspect on nest box temperature. Squirrel gliders (Petaurus norfolcensis) occupied boxes at both locations. I recorded temperatures over a 1-month period in two summers. Temperature varied by up to 20°C within a 24-h period and some nest boxes ...


A New Empirical Correlation For Prediction Of Carbon Dioxide Separation From Different Gas Mixtures, Javad S. Amin, Alireza Bahadori, Tomoaki Kashiwao, Zainal Ahmad, Behrooz A. Souraki, Saeed Rafiee 2016 University of Guilan

A New Empirical Correlation For Prediction Of Carbon Dioxide Separation From Different Gas Mixtures, Javad S. Amin, Alireza Bahadori, Tomoaki Kashiwao, Zainal Ahmad, Behrooz A. Souraki, Saeed Rafiee

Dr Alireza Bahadori

Carbon dioxide (CO2) emission from different systems such as fuel gas (H2+CO2), flue gas (N2+CO2), and biogas gas (CH4+CO2) is one of the main factors of global warming and environmental problems. So, CO2 separation from different systems is essential. Low energy consumption, environmental friendliness, and low operational cost of hydrate-based gas separation (HBGS) process show the high potential of this approach in separation of some gases such as CO2. Hydrate phase equilibrium data are required for designing the separation process. So far numerous models has been proposed for ...

Population Stability In The Endangered Fleay’S Barred Frog (Mixophyes Fleayi) And A Program For Long-Term Monitoring, Gemma Quick, Ross L. Goldingay, Jonathon Parkyn, David A. Newell

Associate Professor Ross L Goldingay

In the wake of the global decline in amphibians there is a need for long-term population monitoring. Previous research suggested that the endangered Fleay’s barred frog (Mixophyes fleayi) had recovered after a severe decline. We aimed to determine whether this recovery has been sustained and to test an example of a monitoring program that could be employed at intervals of five or more years to assess long-term population stability. We conducted capture–mark–recapture five years after the last detailed census at Brindle Creek in Border Ranges National Park, New South Wales. Frogs were captured along a 200 m ...


Determining Methods Of Propagation For The Investigation Of Intraspecific Variability Of Climate Change Responses Of Appalachian Plant Species, Gayle L. Tyree 2016 University of Tennessee at Chattanooga

Determining Methods Of Propagation For The Investigation Of Intraspecific Variability Of Climate Change Responses Of Appalachian Plant Species, Gayle L. Tyree

Honors Theses

Species range migrations are a well-documented response to climate change (Loarie et al. 2009), with range shifts mainly occurring poleward or to higher elevations (Walther et al. 2002). As range shifts occur, variation in phenotypic traits within plant species across climate gradients could affect their abilities to acclimate or adapt to a changing climate (Hooper et al. 2005, Souza et al. 2011). In 2014 Dr. Jennifer Boyd (BGES) initiated a research project to examine potential intraspecific phenotypic variation within wide-ranging Appalachian plant species of responses to projected future atmospheric CO2 and temperature regimes. As an undergraduate research assistant, I focused ...


Alluvial Sedimentation Associated With Logging In Low Gradient Watersheds In Desoto National Forest, Mississippi, Andrew W. Simmons 2016 University of Southern Mississippi

Alluvial Sedimentation Associated With Logging In Low Gradient Watersheds In Desoto National Forest, Mississippi, Andrew W. Simmons

Master's Theses

Forestry and related businesses are an important factor of Mississippi’s economy, contributing between $11 and $14 billion annually (Mississippi Forestry Commission, 2006). The timber industry is not only important in Mississippi but is an important sector of the economy throughout the Gulf Coast region. While providing positive economic benefits to the region, the forestry industry can also negatively affect soil properties, hillslope stability, and increase sedimentation rates in local streams and rivers. The aim of this research is to determine if forestry removal causes an increase of soil erosion and how it affects floodplain sedimentation in the low gradient ...


Feasibility, Safety, Economic And Environmental Implications Of Whey-Recovered Water For Cleaning-In Place Systems: A Case Study On Water Conservation For The Dairy Industry, Yulie E. Meneses 2016 University of Nebraska-Lincoln

Feasibility, Safety, Economic And Environmental Implications Of Whey-Recovered Water For Cleaning-In Place Systems: A Case Study On Water Conservation For The Dairy Industry, Yulie E. Meneses

Dissertations & Theses in Food Science and Technology

Several countries around the world are facing the challenge of producing food with limited water resources for a growing population. This reality is forcing all sectors involved in the food supply chain to look for water conservation strategies that contribute to assure global food security. Besides water consumption, the food industry has to deal with wastewater generation; therefore, water reconditioning and reuse is an attractive solution to address both issues. The goal of this research was to demonstrate that high quality water can be recovered from whey, a by-product of the cheese making process, and reused in cleaning-in place (CIP ...

Gaur (Bos Gaurus) Abundance, Distribution, And Habitat Use Patterns In Kuiburi National Park, Southwestern Thailand, Supatcharee Tanasarnpaiboon

Dissertations & Theses in Natural Resources

Population status of gaur (Bos gaurus), a wild cattle, in most habitats where they are present, is still unknown. As the use of camera traps in wildlife studies are widespread, I developed photographic individual identification procedures and utilized encounter histories of gaur individuals from camera trap data to estimate gaur abundance and density using the spatially explicit capture-recapture analysis. The study was conducted at Kuiburi National Park, southwestern Thailand, comprised of dry evergreen forest, moist evergreen forest, and man-modified secondary forest during November 2013- January 2015. I conducted 71 direct observations in a savannah-like habitat area to observe the numbers ...


Exploring Elementary Students’ Agricultural And Scientific Knowledge Using Evidence Centered Design, Molly R. Brandt 2016 University of Nebraska-Lincoln

Exploring Elementary Students’ Agricultural And Scientific Knowledge Using Evidence Centered Design, Molly R. Brandt

Dissertations & Theses in Natural Resources

The public is more disconnected from agriculture than ever. Americans are two to four generations removed from the farm, and a majority of Americans, even in rural agricultural states have no direct link to agriculture. As a result, the public lacks the knowledge and appreciation of the food, fuel, and fiber it demands. The National Center for Agricultural Literacy (NCAL) uses National Agricultural Learning Objectives (NALOs) to measure student’s agricultural knowledge. The purpose of this project is to develop assessments aligned with the NALOs and to use results from the assessments to further understand students’ agricultural literacy. This study ...


Crafting A Campus Sustainability Action Plan: A Grassroots Approach, Jolina A. Kenney 2016 Gettysburg College

Crafting A Campus Sustainability Action Plan: A Grassroots Approach, Jolina A. Kenney

Celebration

In recent decades, colleges and universities have taken a leadership role in developing institution-based Sustainability Action Plans (SAPs). A SAP includes a summation of past achievements, current initiatives, and the prioritized goals and implementation strategies for future action in terms of promoting environmental sustainability. These plans can also serve as pedagogical devices that teach students, staff and faculty important lessons of intentional living, global citizenship, and environmental responsibility. While many plans are adopted as top-down initiatives, there is great value in finding ways to engage the entire campus community in such endeavors at the grassroots level. This project documents a ...

Effects Of Changes In Moisture Source And The Upstream Rainout On Stable Isotopes In Precipitation – A Case Study In Nanjing, Eastern China, Y. Tang, H. Pang, W. Zhang, Y. Li, Shuang-Ye Wu, S. Hou

Shuang-ye Wu

In the Asian monsoon region, variations in the stable isotopic composition of speleothems have often been attributed to the "amount effect". However, an increasing number of studies suggest that the "amount effect" in local precipitation is insignificant or even non-existent. To explore this issue further, we examined the variability of daily stable isotopic composition (δ18O) in precipitation from September 2011 to November 2014 in Nanjing, eastern China. We found that intra-seasonal variations of δ18O during summer were not significantly correlated with local rainfall amount but could be linked to changes in the moisture source location and rainout processes in the ...

Shuang-ye Wu

Reconstruction of the Hirnantian (Late Ordovician) palaeotopography in South China is important for understanding the distribution pattern of the Hirnantian marine depositional environment. In this study, we reconstructed the Hirnantian palaeotopography in the Upper Yangtze region based on the rankings of the palaeo-water depths, which were inferred according to the lithofacies and biofacies characteristics of the sections. Data from 374 Hirnantian sections were collected and standardized through the online Geobiodiversity Database. The Ordinary Kriging interpolation method in the ArcGIS software was applied to create the continuous surface of the palaeo-water depths, i.e. the Hirnantian palaeotopography. Meanwhile, the line transect ...

The Paranaguá Estuarine Complex (PEC) includes the naturally oligotrophic (NO) Mel Island which is surrounded by sea grasses, a naturally eutrophic (NE) Benito Inlet adjacent to mangrove wetlands and the highly impacted eutrophic (IE) Paranaguá Bay, home of one of Brazil’s largest ports. The results from this study indicate that reactive As and pyrite increase with sediment depth near Paranaguá port in the IE region. At the NE region, near a mangrove fringe, the reactive As, Fe, Mn and pyrite remained relatively high along the sediment column while near the sea grasses at NO the As contents were low ...

Enlightened public opinion ultimately set things right in the Reserve Mining case. Following US. District Judge Miles Lord’s order of April 20, 1974 to cease all taconite tailings discharge to Lake Superior, it took much additional effort by the State of Minnesota, intervening environmental groups and the US. Government to stop the 25-year dumping of hundreds of millions of tons of tailings into the world’s fresh- water treasure. It finally happened in the spring of 1980

The glacial history of the Great Lakes basin and the tremendous influence of the lakes themselves create unique conditions. These support a wealth of biological diversity, including many species and communities of global significance. The basin’s sand dunes, coastal marsh- es, rocky shorelines, lakeplain prairies, savannas, forests, fens and other landscapes contain features that are either unique to or are best represented with- in the Great Lakes basin. The remark- able biodiversity of the Great Lakes basin is illustrated by the Indiana Dunes National Lakeshore. This park ranks third among US. National Parks in plant diversity, yet its area ...
