Women In Conservation: A Study Of Effective Community-Based Conservation And The Empowerment Of Women In Tanzania, Ruby Krietzman

Independent Study Project (ISP) Collection

The subject of this study is women involved in Community-Based Conservation (CBC) from areas surrounding Lake Manyara National Park, Ngorongoro Conservation Area, and Mount Kilimanjaro National Park. CBC is a participatory process between people and organizations who have responsibilities affecting conservation. Communities surrounding protected conservation areas tend to experience high levels of poverty and marginalization due to exclusive conservation policies and the lack of co-management principles. Although tourism revenue is abundant in these locations, the benefits rarely impact local community members that disproportionately experience the effects of conservation. This is especially true for women who hold the responsibilities of collecting …

Beneficial Use Of Dredged Material: Role Of State Permitting Programs And Regulations, Samantha Becker, Sashenka Brauer

Virginia Coastal Policy Center

Beneficial use projects that utilize dredged material will involve several steps: dredging operations, storage of the dredged material, and placement of the dredged material for shoreline resiliency or restoration purposes. Each of these steps implicate different state permitting programs and regulations. Determining which permit programs are applicable will depend on the activity’s impact on the surrounding environment, based on factors such as water quality, and land erosion and degradation. This paper will focus primarily on three questions:

1. Which Virginia permitting programs may apply to the storage of dredged material on an upland site?

2. Which Virginia permitting programs may apply to …

It's Essential: The Ylang-Ylang Trade On Nosy Be, James Sleigh

Independent Study Project (ISP) Collection

This paper attempts to describe the production and sale of Ylang-Ylang from cultivation of the tree to the export of the flower, and examines the roles and power that each stakeholder has in the value chain. From there, the paper will look at issues associated with the trade; namely of the threat to the terrestrial ecosystem and the profit imbalance in the industry. Finally, the paper turns to potential strategies to resolve the previously stated issues associated with the production and sale of Ylang-Ylang. As a whole I hope that the paper can be seen as a rough survey of …

Executive Summary:

In early 2017, Jake Aman, representing the Wells National Estuary Research Reserve (WNERR), met with the Cape Elizabeth Public Works Director and Town Planner to talk about culverts. Jake shared aerial photos of culverts located in the Spurwink Marsh where scouring of adjacent habitat areas was evident. He inquired if the town was considering any culvert replacements, in which case WNERR and The Nature Conservancy might be able to partner with the town to promote a habitat sensitive replacement. The outcome of the meeting was a jointly sponsored assessment of major town culverts, including those located in the …

Convergence Science In The Anthropocene: Navigating The Known And Unknown, David G. Angeler, Craig R. Allen, Ana Carnaval

School of Natural Resources: Faculty Publications

1. Rapidly changing ecological and social systems currently pose significant societal challenges. Navigating the complexity of social-ecological change requires ap- proaches able to cope with, and potentially solve, both foreseen and unforeseen societal challenges.

2. The emergent field of convergence addresses the intricacies of such challenges, and is thus relevant to a broad range of interdisciplinary issues.

3. This paper suggests a way to conceptualize convergence research. It discusses how it relates to two major societal challenges (adaptation, transformation), and to the generation of policy-relevant science. It also points out limitations to the further development of convergence research.

The Case For A Mandatory Renewable Portfolio Standard In Virginia: A Case Study Examining Virginia’S Potential For A Mandatory Renewable Portfolio Standard By Comparing Virginia To Maryland And North Carolina, Rebecca Wescott

William & Mary Environmental Law and Policy Review

Since the early 1980s, states have utilized Renewable Energy Portfolio Standards (“RPSs”) as policy mechanisms to “promote broader investment in renewable energy without requiring passage of a comprehensive energy policy measure that includes a pricing mechanism for carbon.” RPS policies can be drafted in one of two ways: (1) as a mandatory RPS, a legal mandate on what percentage of a state’s power portfolio must come from specific eligible renewable energy sources by a specific date in the future, or (2) as a non-binding or voluntary RPS, a policy goal that recommends that a certain percentage of a state’s power …

Redescription Of Anaschisma (Temnospondyli: Metoposauridae) From The Late Triassic Of Wyoming And The Phylogeny Of The Metoposauridae, Bryan M. Gee, William G. Parker, Adam D. Marsh

United States National Park Service: Publications

Metoposaurids are non-marine temnospondyls that are among the most common constituents of Late Triassic deposits, but despite their abundance, the evolutionary relationships of the group are poorly resolved and have not been fully addressed with modern phylogenetic methods. The genus Anaschisma is one of a number of poorly resolved metoposaurid taxa and was erected to describe two species from the Popo Agie Formation (Carnian) in Wyoming: Anaschisma browni and Anaschisma brachygnatha. Since being named, the genus has been repeatedly synonymized and separated with other taxa in the context of broader revisions of the Metoposauridae. At present, Anaschisma is considered …

Competition And Burn Severity Determine Post-Fire Sapling Recovery In A Nationally Protected Boreal Forest Of China: An Analysis From Very High-Resolution Satellite Imagery, Lei Fang, Ellen V. Crocker, Jian Yang, Yan Yan, Yuanzheng Yang, Zhihua Liu

Forestry and Natural Resources Faculty Publications

Anticipating how boreal forest landscapes will change in response to changing fire regime requires disentangling the effects of various spatial controls on the recovery process of tree saplings. Spatially explicit monitoring of post-fire vegetation recovery through moderate resolution Landsat imagery is a popular technique but is filled with ambiguous information due to mixed pixel effects. On the other hand, very-high resolution (VHR) satellite imagery accurately measures crown size of tree saplings but has gained little attention and its utility for estimating leaf area index (LAI, m²/m²) and tree sapling abundance (TSA, seedlings/ha) in post-fire landscape remains …

Improving Risk Assessment Of The Emergence Of Novel Influenza A Viruses By Incorporating Environmental Surveillance, Kim M. Pepin, Matthew W. Hopken, Susan A. Shriner, Erica Spackman, Zaid Abdo, Colin Parrish, Steven Steven, James O. Lloyd-Smith, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Reassortment is an evolutionary mechanism by which influenza A viruses (IAV) generate genetic novelty. Reassortment is an important driver of host jumps and is widespread according to retrospective surveillance studies.However, predicting the epidemiological risk of reassortant emergence in novel hosts from surveillance data remains challenging. IAV strains persist and cooccur in the environment, promoting co-infection during environmental transmission. These conditions offer opportunity to understand reassortant emergence in reservoir and spillover hosts. Specifically, environmental RNA could provide rich information for understanding the evolutionary ecology of segmented viruses, and transform our ability to quantify epidemiological risk to spillover hosts. However, significant challenges …

Reflecting On Efforts To Design An Inclusive Citizen Science Project In West Baltimore, Amanda E. Sorensen, Rebecca C. Jordan, Shannon L. Ladeau, Dawn Biehler, Sacoby Wilson, John-Henry Pitas, Paul T. Leisnham

School of Natural Resources: Faculty Publications

Citizen science (CS) has been an increasingly utilized means by which scientists leverage members of the public to increase the amount of data collected and analyzed. However, the underrepresentation of individuals from certain socio-cultural groups can have consequences that can manifest in the scientific outcomes of those CS projects such as biases in the data. Additionally, this underrepresentation can potentially affect long-term viability and support of CS as a community of practice. CS programs that promote greater inclusivity would likely provide opportunities for communities to define, investigate, and address pressing issues in collaboration with professional scientists. In this paper we …

Agronomy, Horticulture and Plant Science Faculty Publications

In the Northern Great Plains (NGP), the combined impacts of land-use and climate variability have the potential to place many soils on the tipping point of sustainability. The objectives of this study were to assess if the conversion of grassland to croplands occurred on fragile landscapes in the North America Northern Great Plains. South Dakota and Nebraska were selected for this study because they are located in a climate transition zone. We visually classified 43,200 and 38,400 points in South Dakota and Nebraska, respectively, from high-resolution imagery in 2006, 2012, and 2014 into five different categories (cropland, grassland, habitat, NonAg, …

Overcoming Impediments To Shellfish Aquaculture Through Legal Research And Outreach: Case Studies, National Sea Grant College Program, Catherine Janasie, Amanda Nichols, Read Porter, Mitchell Ramic, Jordan Viana, Joseph Bingaman, Elizabeth Andrews, Angela King, Danielle Goshen, Shana Jones, Lisa Schiavinato, Catherine Courtier, Danielle Goshen

Virginia Coastal Policy Center

More than half of the population of the continental United States resides in coastal communities, which are increasingly home to commercial shellfish aquaculture operations. Consequently, a variety of user conflicts can arise as states seek to encourage the development or expansion of shellfish aquaculture. Each of these conflicts creates the potential for opposition and legal challenges to the industry.

An understanding of the legal and regulatory context governing shellfish aquaculture can assist in managing conflicts related to the industry. Laws and regulations in some cases create or can be perceived as impediments to the growth or success of the aquaculture …

Limits To The World’S Green Water Resources For Food, Feed, Fiber, Timber, And Bioenergy, Joep F. Schyns, Arjen Y. Hoekstra, Martijn J. Booij, Rick J. Hogeboom, Mesfin Mekonnen

Daugherty Water for Food Global Institute: Faculty Publications

Green water––rainfall over land that eventually flows back to the atmosphere as evapotranspiration––is the main source of water to produce food, feed, fiber, timber, and bioenergy. To understand how freshwater scarcity constrains production of these goods, we need to consider limits to the green water footprint (WFg), the green water flow allocated to human society. However, research traditionally focuses on scarcity of blue water––groundwater and surface water. Here we expand the debate on water scarcity by considering green water scarcity (WSg). At 5 × 5 arc-minute spatial resolution, we quantify WFg and the maximum sustainable level to this footprint (WFg,m), …

Potential Economic Impacts Of Allocating More Land For Bioenergy Biomass Production In Virginia, Thomas O. Ochuodho, Janaki R. R. Alavalapati, Pankaj Lal, Domena A. Agyeman, Bernabas Wolde, Pralhad Burli

Forestry and Natural Resources Faculty Publications

The growing attention to renewable energy and rural development has created greater demand for production of biomass feedstock for bioenergy. However, forest growth rates and the amount of land in most existing forests may not be sufficient to sustainably supply the forest biomass required to support existing forest products industries and the expanding bioenergy industry. Additionally, concerns about agricultural land use competition have dampened expansion of biomass production on agricultural land base. One of the ways to meet the growing forest biomass feedstock demand for bioenergy production is by allocating currently marginal non-forested land for growing bioenergy feedstocks. In Virginia, …

Hunter And Angler Motivations, Preferences, And Barriers To Waterfowl Hunting In The Central United States, Matthew P. Hinrichs

School of Natural Resources: Dissertations, Theses, and Student Research

Since the mid-1980s, there has been a decrease in individuals participating in waterfowl hunting in the United States. The decline in participation has over-arching consequences for state and federal wildlife agencies in their ability to fund and manage habitat and waterfowl populations. There is a fundamental need to understand why individuals participate in waterfowl hunting and what barriers there are to participating in waterfowl hunting. An online survey was conducted in the summer and fall of 2018 asking waterfowl hunters, anglers, big game hunters, combination users (i.e., hunters that have multiple hunting and fishing permits), and small game hunters about …

Sampling Related Individuals Within Ponds Biases Estimates Of Population Structure In A Pond‐Breeding Amphibian, Kyle A. O'Connell, Kevin P. Mulder, Jose Maldonado, Kathleen L. Currie, Dennis M. Ferraro

School of Natural Resources: Faculty Publications

Effective conservation and management of pond‐breeding amphibians depends on the accurate estimation of population structure, demographic parameters, and the influence of landscape features on breeding‐site connectivity. Population‐level studies of pond‐breeding amphibians typically sample larval life stages because they are easily captured and can be sampled nondestructively. These studies often identify high levels of relatedness between individuals from the same pond, which can be exacerbated by sampling the larval stage. Yet, the effect of these related individuals on population genetic studies using genomic data is not yet fully understood. Here, we assess the effect of within‐pond relatedness on population and landscape …

Wildfire Alters Spatial Patterns Of Available Soil Nitrogen And Understory Environments In A Valley Boreal Larch Forest, Jianjian Kong, Jian Yang, Bo Liu, Lin Qi

Forestry and Natural Resources Faculty Publications

Wildfire, a primary natural disturbance in many forests, affects soil nutrient availability and spatial distributions of forest plants. However, post-fire changes in soil nutrients and spatial patterns of understory environments at fine scales are poorly understood. Here, we characterized spatial patterns of soil nitrogen availability and site characteristics at a 3-year-post-fire and an unburned site in a valley boreal larch forest. We also examined the relationship between soil nitrogen availability and site characteristics. The results showed that the burned site had higher NO₃⁻ and lower NH₄⁺ than the control. The herb, litter and coarse wood debris …
