Using Capture-Mark-Recapture Techniques To Estimate Detection Probabilities & Fidelity Of Expression For The Critically Endangered James Spinymussel (Pleurobema Collina)., Alaina C. Esposito
Using Capture-Mark-Recapture Techniques To Estimate Detection Probabilities & Fidelity Of Expression For The Critically Endangered James Spinymussel (Pleurobema Collina)., Alaina C. Esposito
Masters Theses, 2010-2019
The critically endangered James Spinymussel (Pleurobema collina) is a species of freshwater mussel endemic to Virginia’s James and Dan River basins. In the last 20 years, P. collina has experienced a substantial decline in numbers and currently occupies approximately 10% of its original habitat; however, little information is known about this species to assist in conservation. A 230-meter reach of transitional habitat in Swift Run was selected for repeat observations to estimate detection probabilities using a Capture-Mark-Recapture framework. In June 2014, visual scouting began to locate and tag P. collina (including other mussels in the community) with PIT …

Seasonal Warm-Water Refuge And Sanctuary Usage By The Florida Manatee (Trichechus Manatus Latirostris) In Kings Bay, Citrus County, Florida, Danielle C. Sattelberger
HCNSO Student Theses and Dissertations
The largest Florida manatee (Trichechus manatus latirostris) aggregation at a natural warm-water refuge occurs in Kings Bay, Crystal River, FL. Over the last 32 years, the U.S. Fish and Wildlife Service and the State of Florida have created a network of manatee protection areas within Kings Bay including a year-round refuge designation and seven Federal manatee sanctuaries during the winter manatee season (November 15 – March 31). Aerial survey data collected between 1983 and 2012 was used to examine the seasonal change in manatee distribution within Kings Bay in order to assess the effectiveness of current sanctuary sizes …

School of Natural Resources: Faculty Publications
Diversion (i.e. extraction) of water from rivers and estuaries can potentially affect native wildlife populations if operation is not carefully managed. For example, open, unmodified water diversions can act as a source of injury or mortality to resident or migratory fishes from entrainment and impingement, and can cause habitat degradation and fragmentation. Fish-protection devices, such as exclusion screens, louvres or sensory deterrents, can physically or behaviourally deter fish from approaching or being entrained into water diversions. However, empirical assessment of their efficacy is often lacking or is investigated only for particular economically or culturally important fishes, such as salmonids. The …
Effects Of Alternative Framing On The Publics Perceived Importance Of Environmental Conservation, Amanda E. Sorensen, Daniel Clark, Rebecca C. Jordan
Effects Of Alternative Framing On The Publics Perceived Importance Of Environmental Conservation, Amanda E. Sorensen, Daniel Clark, Rebecca C. Jordan
School of Natural Resources: Faculty Publications
Effective communication of science to the general public is important for numerous reasons, including support for policy, funding, informed public decision making, among others. Prior research has found that scientists participating in public policy and public communication must frame their communication efforts in order to connect with audiences. A frame is the mechanism that individuals use to understand and interpret the world around them. Framing can encourage specific interpretations and reference points for a particular issue or event; especially when meaning is negotiated between the media and public audiences. In this study, we looked at the effect of framing within …

Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta
Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta
Legacy Theses & Dissertations (2009 - 2024)
Many planning and land use decisions in New York State are controlled at the local (town or municipal) level, not an optimal scale for planning and implementing resource conservation management. Watershed boundaries provide a more ecologically meaningful scale for conservation, because they capture a full range of natural ecosystem processes that span political boundaries. However, defining an urban watershed is complicated by stormwater infrastructure, so standard topographic watershed boundaries may be inadequate for urban resource conservation even when applied at the watershed scale. Storm-watersheds distort both municipal and watershed boundaries, because the flows are redirected in ways that are often …

Conservation Of Grassland Plant Genetic Resources Through People Participation, D. R. Malaviya, Ajoy K. Roy, P. Kaushal
IGC Proceedings (1977-2023)
Agrobiodiversity provides the foundation of all food and feed production. Hence, need of the time is to collect, evaluate and utilize the biodiversity globally available. Indian sub-continent is one of the world’s mega centers of crop origins. India possesses 166 species of agri-horticultural crops and 324 species of wild relatives. India is reported to have five grass covers identified. There have been almost nil human interference in terms of selection pressure; hence, the biodiversity is well conserved in these grazing lands. There is need of a system approach to understanding biodiversity that moves significantly beyond taxonomy and species observations. In …

Stakeholder Perceptions Of Sustainable Value And Water Conservation: A Case Study Of Social, Environmental, And Economic Concerns In The Rookery Bay Estuary, Bruce Victor Lilyea
Department of Conflict Resolution Studies Theses and Dissertations
Stakeholders’ perceptions of social, environmental, and economic concerns in the Rookery Bay Estuary were examined through this research. The purpose of this study was to discover the shared value and common resolution responses for the people of the Rookery Bay area that can extend to other local environmental management scenarios. Using Stakeholder Theory, Rational Choice Theory, Symbolic Interactionism, and Systems Theory as theoretical foundation, the following research questions were considered: RQ1) What are the points of shared value of community stakeholders facing environmental management issues? RQ2) How do the perspectives of the community stakeholders toward the social, environmental, and economic …
Site-Specific Habitat And Landscape Associations Of Rusty Blackbirds Wintering In Louisiana, Sinead Mary Borchert
Site-Specific Habitat And Landscape Associations Of Rusty Blackbirds Wintering In Louisiana, Sinead Mary Borchert
LSU Master's Theses
The Rusty Blackbird (Euphagus carolinus) has gained notoriety in recent years as one of the fastest declining North American bird species, with a global population loss of as much as 95%. Causes of the decline are not completely understood, but the high rate of forested wetland change in the southeastern United States suggests that wintering habitat degradation may be a primary driver. To better inform management on critical wintering grounds, I surveyed 68 sites in Louisiana where Rusty Blackbirds had been known to occur to address how occupancy changes with habitat type and colonization and extinction rates vary with ground …
The Role Of Hybridization And The United States Fish And Wildlife Service Biologists’ Discretion In The Implementation Of The Endangered Species Act, Jennifer F. Lind-Riehl
The Role Of Hybridization And The United States Fish And Wildlife Service Biologists’ Discretion In The Implementation Of The Endangered Species Act, Jennifer F. Lind-Riehl
Dissertations, Master's Theses and Master's Reports - Open
The Endangered Species Act (ESA) requires that the “best available scientific and commercial data” be used to enable the protection of critically imperiled species from extinction and preserve biodiversity. However, the ESA does not provide specific guidance on how to apply this mandate. In addition, the interpretation of scientific data can be uncertain and controversial, particularly regarding species delineation and hybridization issues. US Fish and Wildlife Service (FWS) field biologists must decide what the best science is and how to interpret and apply it in their recommendations. As a result, FWS field biologists often have considerable discretion when it comes …

Croakers (Sciaenidae) are major fishery resource in Brazil; constituting 22% of marine and 9% of freshwater fishery landings. Croakers are subject to heavy fishing pressure throughout Brazil, but habitat alteration is also an important threat to regional populations. In this regional Sciaenidae assessment, each species was analyzed for relative risk of extinction, including the identification and quantification of the impact of major threats and existing conservation measures, based on application of the Categories and Criteria of the IUCN Red List of Threatened Species. Of the 52 species of Sciaenid fishes (34 marine and 18 freshwater) present in Brazilian waters, the …
A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz
A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz
Graduate Student Theses, Dissertations, & Professional Papers
Chile's state designated protected areas are reported to show representation bias and to be unable to meet conservation goals. Private protected areas are considered an important tool to resolve these issues, which has led to support for increasing the role of private protected areas in Chile and creating an integrated public-private protected area network. But the validity of the capacity of private protected areas to fix Chile's state protected area network bias, and the advantage of creating an integrated protected area network, have not been assessed. This study uses the most recent data on Chile's state, private, and international protected …

Honors Theses
As a result of a long-term longline study conducted by Coastal Carolina University, data on the population structure of sharks in Winyah Bay, SC have been recorded since 2002. The data are collected from late spring to fall each year. Two separate data sets, from 2002 to 2006 and from 2012 to 2014, were analyzed for catch per unit effort (CPUE), catch composition, sex ratios, and average precaudallengths (PCL) for males and females. The average CPUE for the 2002-2006 data set was 2.68 with a standard deviation of 0.73 while the average for the most recent data set was 3.20 …
Irrigation Tips To Conserve Water And Grow A Healthy Lawn, Gregg Munshaw, Brad Lee
Irrigation Tips To Conserve Water And Grow A Healthy Lawn, Gregg Munshaw, Brad Lee
Agriculture and Natural Resources Publications
Turfgrasses are composed of thousands of cells, all containing water, in which metabolic processes such as photosynthesis and respiration take place. Water makes up 80 to 90 percent of the total plant mass. If this level drops below 60 percent, these processes may slow and wilting will occur. Water is critically important for:
- Maintaining turgidity, which keeps plants standing upright
- Transporting nutrients and sugars through the plant
- Chemical reactions
- Transpirational cooling when water moves out of the leaves and evaporates

Planning For Adaptation To Climate Change: Lessons From The Us National Wildlife Refuge System, Robert L. Fischman, Vicky J. Meretsky, Alexei Babko, Michael Kennedy, Lei Liu, Michelle Robinson
Articles by Maurer Faculty
US national wildlife refuges have recent, detailed management plans illustrating the state of planning for climate-change adaptation in protected areas. Discussion of and prescriptions for addressing climate change increased in refuge plans between 2005 and 2010 but decreased in 2011. The plans respond to some climate-change impacts on biodiversity and call for monitoring but with little clarity regarding how to act on monitoring results and scant attention to future changes in phenology and community composition. The threats posed by sea-level rise generated the best-developed plan prescriptions. Examples of excellent prescriptions provide models for future planning. Some decision-support tools, such as …

Historic Distribution And Ecology Of Tall-Grass Prairie In Western Canada, Darcy C. Henderson, Nicola Koper
Historic Distribution And Ecology Of Tall-Grass Prairie In Western Canada, Darcy C. Henderson, Nicola Koper
The Prairie Naturalist
Rapid settlement and agricultural development of western Canada in the late 1800s and early 1900s nearly eliminated the tall-grass prairie, and pre-empted a detailed description by ecologists. A combination of literature review and historical ecological analysis of soils, climate, and composition data are applied to estimate the historic distribution, and area occupied by tall-grass prairie in southern Manitoba and southeastern Saskatchewan, Canada. The resulting area estimate of 20,830 km2 is more than three times any previously reported value. Some confusion of terms from the first half of the 1900s, and the impact of invasive species on vegetation patterns observed …
14 Conservation Of Energy, Charles G. Torre
14 Conservation Of Energy, Charles G. Torre
Foundations of Wave Phenomena
After all of these developments it is nice to keep in mind the idea that the wave equation describes (a continuum limit of) a network of coupled oscillators. This raises an interesting question. Certainly you have seen by now how important energy and momentum — and their conservation — are for understanding the behavior of dynamical systems such as an oscillator. If a wave is essentially the collective motion of many oscillators, might not there be a notion of conserved energy and momentum for waves? If you’ve ever been to the beach and swam in the ocean you know that …

Just before Thanksgiving Day last November, Kent Wommack '77 got the classic good-news, bad-news, worse-news call. Wommack is head of The Nature Conservancy in Maine, and the caller was a timberland manager who had asked Wommack to back a client in acquiring prime acres of Maine forest on the upper St. John River, one of the most unspoiled waterways left in the United States. The good news was that the owner had agreed to sell the breathtaking chunk of land in the first place. The bad news was that the client was no longer interested in the deal. The worse …

Website created by Angelina McKee to educate the public about water resource issues. Water is the basic unit of life, water resources are the basis for what societies and ecosystems are founded upon. Water shortages and droughts are more prevalent in our ever-changing world. It is no shock that there are discrepancies between various stockholders on either sides of the dry riverbed. This senior project resulted in the development of a website that addresses global water resources, water use in California, water conservation, and water allocation. The website informs the public on water resources and related issues and will hopefully …
Global Population Structure Of The Dusky Shark And Geographic Sourcing Of Shark Fins From Commercial Markets, Teagen K. Gray
Global Population Structure Of The Dusky Shark And Geographic Sourcing Of Shark Fins From Commercial Markets, Teagen K. Gray
HCNSO Student Theses and Dissertations
The dusky shark, Carcharinus obscurus, is a globally distributed, coastal-pelagic species subject to an apparent high level of exploitation. The International Union for the Conservation of Nature (IUCN) lists this species as “Vulnerable” globally, and “Endangered” within western North Atlantic and Gulf of Mexico waters due to an over 80% decline in this region, with no evidence of population recovery. The extensive exploitation of dusky sharks may partly be attributed to the high market value of its fins, but the contribution of individual dusky shark stocks to the fin markets is unknown. This knowledge would be helpful to detect …
Understanding The Role Of Trust In Cooperation With Natural Resources Institutions, Joseph A. Hamm
Understanding The Role Of Trust In Cooperation With Natural Resources Institutions, Joseph A. Hamm
Department of Psychology: Dissertations, Theses, and Student Research
This dissertation investigates the role of trust in predicting cooperation with a natural resources management institution. It begins with an exploration of the legal landscape against which the relationship between land owners and natural resources management institutions is contextualized, presents a review of the often ostensibly disparate trust literature and a framework for its integration, and proposes and tests a model of trust and cooperation in the natural resources context. The results provide mixed support for the model as proposed but confirm the importance of trust in this context and suggest implications for policy, especially the potential importance of increasing …
