Trap-Neuter-Return Programs And The Importance Of Associated Public Awareness, Nicolette Sliwa

Biology: Student Scholarship & Creative Works

The focus of this paper is to describe a typical Trap-Neuter-Return (TNR) program and highlight the major pros and cons surrounding this somewhat controversial method of managing the overwhelming free-roaming cat population. The effects of the species’ overabundance on the environment and human health are also discussed. Citing studies completed on TNR programs around the globe as well as mathematical models, the effectiveness of this method is compared to other, currently used alternatives. Finally, it has been suggested that the general awareness level a neighborhood possesses about the true goals of TNR programs has a potentially significant impact on the …

Small-Scale Farming Of Sandfish (Holothuria Scabra) At Unguja Ukuu, Zanzibar, Claire Hacker

Independent Study Project (ISP) Collection

The biological and social components of sandfish farming were studied at Unguja Ukuu, Zanzibar. Measurement of temperature and depth, along with quadrat sampling of substrate and sea cucumbers, led to recommendations for future management of depth, biomass per area, disease and crabs, and substrate. Interviews revealed the role and potential benefits of sea cucumber farming for communities. Several barriers to, and complications with, the expansion of sea cucumber farming were also identified. This study provided information for improvement of this farm and hoped to spread knowledge of sandfish farming to Zanzibaris, who may benefit economically from the practice.

Agrarian Reform In Sumber Klampok, Emma Trainor

Independent Study Project (ISP) Collection

Agrarian reform in Indonesia is part of a movement beginning after independence was gained in 1945. Farmers have been fighting to obtain rights to their land from a government that has a history of violence, repression, and corruption for decades. Environmental, indigenous peoples’, peasant, and agrarian movements were given a legitimate, legal framework to work within after 1960 when the Basic Agrarian Law was passed, protecting the rights of the people to their land. However, during both the Old Order and especially New Order regimes, the law was often ignored by the government, and many grassroots organizations had to work …

The Coastal Monitor

There is something enchanting and vibrant about viewing the coast. Every day at CERCOM we are welcomed by either a vivid sunrise, a view of the barrier island Fire Island and a blending of the sky across the horizon, ultimately flooding the Great South Bay with either clouds or sunshine that reveals the Bay’s surface as either shimmering with sunlight, or an integration of sky and water as an endless ocean. I don’t normally wax poetic but the varying sights along the near shore ocean and this embayment beckon our scientific inquisitiveness. What’s below the surface water? How do animals …

China: Avoiding Impediments To Successful Climate Change Mitigation, Molly Rose Van Engelenhoven

Undergraduate Honors Capstone Projects

This paper uses the Cultural Topography (CTOPs) methodology, an intelligence community standard which is used to avoid ethnocentric analysis and the dangerous practice of mirror imaging--projecting US culture on to another country rather than viewing the costs and benefits they face through their own cultural lens. CTOPs assess a country’s culture by examining four components of culture: identity, values, norms, and perceptual lens of an actor in conjunction with a specific issue of concern. This paper examines the internal culture of China, with the Chinese government as the key actor, to discover how to build effective policy to regulate air …

A Compromised Liver Alters Polychlorinated Biphenyl-Mediated Toxicity, Banrida Wahlang, Jordan T. Perkins, Michael C. Petriello, Jessie B. Hoffman, Arnold J. Stromberg, Bernhard Hennig

Superfund Research Center Faculty Publications

Exposure to environmental toxicants namely polychlorinated biphenyls (PCBs) is correlated with multiple health disorders including liver and cardiovascular diseases. The liver is important for both xenobiotic and endobiotic metabolism. However, the responses of an injured liver to subsequent environmental insults has not been investigated. The current study aims to evaluate the role of a compromised liver in PCB-induced toxicity and define the implications on overall body homeostasis. Male C57Bl/6 mice were fed either an amino acid control diet (CD) or a methionine-choline deficient diet (MCD) during the 12-week study. Mice were subsequently exposed to either PCB126 (4.9 mg/kg) or the …

Herpetoplogical Survey Across Three Distinct Habitats In Ankarana National Park: Long-Term Effects Of Past Land Use On Species Composition In And Around The Park, Julia Park

Independent Study Project (ISP) Collection

Ankarana National Park is home to a diverse population of herpetofauna. In this study, three distinct habitats in and around Ankarana National Park were surveyed for herpetological diversity. These habitats were defined as the deciduous forest located within the “tsingy” limestone karst canyons, the dry deciduous forest outside of the canyons, within the borders of the park, and the anthropogenically affected forest outside of the park’s borders, which is subject to logging and fruit tree harvesting. A total of 27 species of herpetofauna – six amphibian and 21 reptile species were found over the course of twelve days of surveying …

Saving Money While Participating In Urban Agriculture, Jill Wieneke

Department of Environmental Studies: Undergraduate Student Theses

With more and more people pouring into urban areas, many have become unattached to where their food comes from and are disengaged with local food systems. Urban agriculture (UA) can bring people closer to healthy foods and be a potential savings. This will bring more resilience to a community and amend food insecurities Through this case study at the Hawley Hamlet Neighborhood Garden, urban gardeners can understand the capabilities of UA and the effects of food affordability into urban settings. This case study is an example of vegetable outputs and cost savings that can be obtained at a community garden …

Management Strategy Evaluation For The Atlantic Surfclam (Spisula Solidissima) Using A Spatially Explicit, Vessel-Based Fisheries Model, Kelsey M. Kuykendall, Eric N. Powell, John M. Klink, Paula T. Moreno, Robert T. Leaf

CCPO Publications

The commercially valuable Atlantic surfclam (Spisula solidissima) is harvested along the northeastern continental shelf of the United States. Its range has contracted and shifted north, driven by warmer bottom water temperatures. Declining landings per unit of effort (LPUE) in the Mid-Atlantic Bight (MAB) is one result. Declining stock abundance and LPUE suggest that overfishing may be occurring off New Jersey. A management strategy evaluation (MSE) for the Atlantic surfclam is implemented to evaluate rotating closures to enhance Atlantic surfclam productivity and increase fishery viability in the MAB. Active agents of the MSE model are individual fishing vessels with …

Influences Of Catch-And-Release Angling On Fish Avoidance Behavior, Alexis D. Fedele

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

Newly opened recreational fisheries provide the opportunity to explore direct social impacts on controlled (i.e., managed), naïve (i.e., previously unexploited by anglers) population of fish. Herein, we examine the direct influence of angling on wild fish populations, and aim to identify the behavioral outcomes in fish resulting from angling through laboratory experiments. Using two naïve fish populations from newly opened reservoirs in Nebraska, we assessed the short-term (30 d) response of fish populations to recreational angling. At one reservoir, we noted declining catch rates in catch-and-release regulated fish but not in harvested-regulated fish. We hypothesized that catch-and-released fish were given …

Climate Change, Managed Relocation, And The Risk Of Intra-Continental Plant Invasions: A Theoretical And Empirical Exploration Relative To The Flora Of New England, Jesse Bellemare, Bryan Connolly, Dov F. Sax

Biological Sciences: Faculty Publications

The high rate of anthropogenic climate change projected for coming decades and evidence of low migration ability for many species have led researchers to warn of a looming extinction crisis. This threat is expected to be most acute for small-ranged endemic species, which could see novel climatic conditions develop rapidly across the entirety of their limited geographic ranges. To avoid extinctions, some conservationists have proposed that climateimperiled species might be candidates for "assisted colonization" or "managed relocation" to new regions, outside their historical ranges. One major concern related to managed relocation is the possibility that some relocated species could later …

Surveying The Distributions Of Melaleuca Quinquenervia, Psidium Cattleianum, And Litsea Glutinosa At Analalava Special Reserve, Hanusia Higgins

Independent Study Project (ISP) Collection

This study surveyed the distributions of three invasive plant species, Melaleuca quinquenervia, Psidium cattleianum, and Litsea glutinosa at the Analalava Special Reserve in Mahavelona, Madagascar. Analalava is a 229-hectare degraded patch of low-elevation humid forest on the northeast coast of Madagascar, and one of the last forest fragments remaining in the region. It is a haven for biodiversity, containing 343 recorded species of plants, 12 of which are locally endemic. Invasive species are considered the second-most significant threat to biodiversity, both worldwide and specifically at Analalava. Based on a systematic transect survey of these three targeted invasive species, their distributions …

Tourism In Raja Ampat: New Chances And Challenges, Chloe King

Independent Study Project (ISP) Collection

This study focuses on the ways in which the tourism industry in Raja Ampat has contributed to local livelihoods and encouraged the preservation of marine resources, looking specifically at the case of a dive operator and a volunteer tourism operation. The study illuminates the challenges that these operators face when engaging with the local community to protect the environment, and recommends more effective strategies for improving relations between tourism operators and the communities in which they reside. The study ultimately makes the case that the legacy of colonial rule in Western Papua must be a consideration in tourism planning, as …

The Roles Of Activism And Citizen Science In The Area Covered By The East Gippsland Regional Forest Agreement, Ian Corbet

Independent Study Project (ISP) Collection

For this Independent Study Project, I have examined the roles of activism and citizen science under the East Gippsland Regional Forestry Act. I conducted the study in the hopes of understanding better how activists have contributed to the overall conservation of the forests of East Gippsland. As the government has recently extended the twenty year agreement for another year, I wanted to determine if the real stakeholders of the conservation movement were taken into account. I sought the perspectives of people involved in the either the administration, implementation or opposition to the RFA. This ended up being eight people in …

Decadal Vegetation Succession Along A Chronosequence Within Eucalyptus Obliqua Wet Forest, Southern Tasmania, Christine Dobbin

Independent Study Project (ISP) Collection

Southern Tasmania is home to fire dependent mixed forests, which, if not maintained, will eventually be replaced by the rainforest understorey. Wet eucalypt forest succession after disturbance events was investigated through floristic and vertical measurements of four north facing chronosequence plots with labels describing the age class of each, from regrowth to mature sites. This study was possible due to the establishment of permanent 50m x 50m plots in 2007 for longitudinal monitoring and subsequent illustration of forest dynamics following disturbance, including clearfell burns and wildfire. The contents of this report are the comparative analyses of the findings from the …

What, Where, Why: A Survey Of Felidae Populations At Enashiva Nature Refuge, Tanzania, Lucrecia Aguilar

Independent Study Project (ISP) Collection

As felid populations worldwide continue to deteriorate due to human activities, understanding how felid species utilize various landscapes, along with what factors affect such use or disuse, becomes essential to the preservation of these species. While previous research has examined felid populations around the world, many species and locations remain understudied. This study surveyed felid species at Enashiva Nature Refuge (ENR) in the Serengeti-Mara ecosystem to determine (1) what felid species are present at ENR, (2) where these species generally occur, and (3) why felids reside at ENR in low or high numbers. Through the use of opportunistic camera trapping, …

Multi-Scaled Approaches For Protecting Montana's Watersheds And Water Resources, Elizabeth Yoder

Graduate Student Portfolios, Professional Papers, and Capstone Projects

The central theme carried among my four portfolio pieces is: using scientific and governmental approaches to conserve watershed health. For the purposes of this portfolio, I define watershed health as a very general term that describes the state of water quantity and quality that is available for human and ecosystem needs in a watershed. I see each of my portfolio pieces focusing on a different scale and method (i.e., science or government, including different levels of government, local, state and federal) for conserving watershed health. My first portfolio piece reviews water quality degradation caused by pharmaceuticals and personal care products …

Getting That Sinking Feeling: Analysis And Impacts Of Sea Level Rise On Three National Parks Along The East Coast, Usa, Julia K. Deros, Amanda L. Thibault, Amy B. True

Student Publications

Due to global climate change, sea level rise (SLR) has become a threat for future generations, but the extent of this danger is unknown. To help understand the possible effects of SLR on the east coast of the United States, we studied three national parks: Acadia National Park (ACAD), Assateague Island National Seashore (ASIS) and Everglades National Park (EVER). We predicted that ACAD would be less affected by SLR than ASIS and EVER due to the construction of its beach profile. By measuring the beach profile, we found that Sand Beach in ACAD was reflective with an average slope of …

Distribution And Condition Of Stony Corals In The Veracruz Reef System National Park: A Management Perspective, Mauricio López Padierna

HCNSO Student Theses and Dissertations

The Veracruz Reef System (VRS) is located in the southwestern Gulf of Mexico. It is comprised of 28 coral reefs in various stages of development and conservation. They are protected under the Parque Nacional Sistema Arrecifal Veracruzano National Park created in 1992. There are many threats to the reefs of the VRS, including the Port and city of Veracruz, which hosts half a million inhabitants and Mexico’s oldest active port. The inhabitants of Veracruz have used reef resources for thousands of years, as evidenced in archaeological sites on Sacrificios island, and constructions throughout the city, most notably in the San …

A Critical Analysis Of The Direct Effects Of Dredging On Fish, Amelia S. Wenger, Euan S. Harvey, Shaun K. Wilson, Christopher A. Rawson, Stephen J. Newman, Douglas Clarke, Benjamin J. Saunders, Nicola Browne, Michael J. Travers, Jennifer L. Mcilwain, Paul L A Erftemeijer, Jean-Paul A. Hobbs, Dianne L. Mclean, Martial Depczynski, Richard D. Evans

Fisheries Research Articles

Dredging can have significant impacts on aquatic environments, but the direct effects on fish have not been critically evaluated. Here, a meta-analysis following a conservative approach is used to understand how dredging-related stressors, including suspended sediment, contaminated sediment, hydraulic entrainment and underwater noise, directly influence the effect size and the response elicited in fish across all aquatic ecosystems and all life-history stages. This is followed by an in-depth review summarizing the effects of each dredging-related stressor on fish. Across all dredging-related stressors, studies that reported fish mortality had significantly higher effect sizes than those that describe physiological responses, although indicators …

The Giving Trees: The (Un)Sustainability Of Palm Oil In Indonesia, Amber Rosche

Seaver College Research And Scholarly Achievement Symposium

Palm oil is the main source of cooking oil for much of Africa, Asia and Brazil. Due to the increasingly high demand for palm oil, countries such as Indonesia and Malaysia have cleared millions of acres of tropical rainforests to create space for oil palm plantations. This deforestation has led to extreme environmental and social concerns such as the burning of peatlands, the endangerment of a number of species, including the Sumatran Tiger, rhinos and orangutans, and the displacement of native populations. Indonesia is the world’s largest consumer and producer of palm oil, producing almost half of the world’s supply …

Abundance And Habitat Preferences Of Introduced Muscovy Ducks (Cairina Moschata), Jacqueline Marie Perry Cahanin

USF Tampa Graduate Theses and Dissertations

Muscovy ducks are native only to Central and South America, Mexico, and parts of southern Texas and are considered invasive in some areas outside of their native range. Although they have been introduced worldwide, they remain largely unstudied. The primary focus of this study was to relate Muscovy duck abundance to habitat characteristics of wetlands in Tampa, Florida. Muscovy abundance was measured using point count methods at 21 wetland sites that occur within an eight km radius of the University of South Florida’s main campus. Habitat features at these sites were assessed using field methods and Geographic Information Systems (GIS) …

Stormwater Infiltration And Groundwater Integrity: An Analysis Of Bmp Siting Tools And Groundwater Vulnerability, Kristopher Craig Gallagher

USF Tampa Graduate Theses and Dissertations

Nonpoint source pollution captured by urban stormwater runoff is the greatest challenge for surface water quality improvements. Computer-based design tools have been developed to help mediate this issue by guiding end users through the implementation of decentralized stormwater management. The majority of these tools focus on treatment via biofiltration, yet concern regarding this treatment regime is rising. Case studies from research past clearly indicate the susceptibility of groundwater to contamination from extensive anthropogenic activity at the surface. Contaminants, such as nitrates and pathogens, are not completely removed before runoff enters the underground watercourse. Additionally, national and state legislation, which explicitly …

Patterns In Greater Sage-Grouse Population Dynamics Correspond With Public Grazing Records At Broad Scales, Adrian P. Monroe, Cameron L. Aldridge, Timothy J. Assal, Kari E. Veblen, David A. Pyke, Michael L. Casazza

Wildland Resources Faculty Publications

Human land use, such as livestock grazing, can have profound yet varied effects on wildlife interacting within common ecosystems, yet our understanding of land-use effects is often generalized from short-term, local studies that may not correspond with trends at broader scales. Here we used public land records to characterize livestock grazing across Wyoming, USA, and we used Greater Sage-grouse (Centrocercus urophasianus) as a model organism to evaluate responses to livestock management. With annual counts of male Sage-grouse from 743 leks (breeding display sites) during 2004-2014, we modeled population trends in response to grazing level (represented by a relative grazing index) …
