Interacting With The Trail: A Comprehensive Approach To Developing An Environmental Education Program For Agnolakely Private Nature Reserve, Claire Hamilton

Independent Study Project (ISP) Collection

Madagascar is a diverse island, biologically and geographically. This has led to the development of endemic species and high biodiversity within the landscape. Unfortunately, due to poverty, extraction of natural resources, and a growing population, these species have become threatened. Agnolakely, is a private nature reserve, located in eastern Madagascar that is trying to combat these challenges through reforestation projects and land protection. Agnolakely is not only of ecological value, but is also integral in the community structure. As Agnolakely expands it has become essential to implement education and outreach for the reserve. This study was designed to collect biological …

Agroforestry Standards For Regenerative Agriculture [Review], Craig R. Elevitch, D. Niki Mazaroli, Diane Ragone Jan 2018

Agroforestry Standards For Regenerative Agriculture [Review], Craig R. Elevitch, D. Niki Mazaroli, Diane Ragone

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Agroforestry is increasingly being recognized as a holistic food production system that can have numerous significant environmental, economic, and social benefits. This growing recognition is paralleled in the USA by the budding interest in regenerative agriculture and motivation to certify regenerative practices. Current efforts to develop a regenerative agriculture certification offer an opportunity to consider agroforestry’s role in furthering regenerative goals. To understand this opportunity, we first examine how agroforestry practices can advance regenerative agriculture’s five core environmental concerns: soil fertility and health, water quality, biodiversity, ecosystem health, and carbon sequestration. Next, we review a subset of certification programs, standards, …

Conserving All The Pollinators: Variation In Probability Of Pollen Transport Among Insect Taxa, Diane L. Larson, Jennifer L. Larson, Deborah A. Buhl Jan 2018

Conserving All The Pollinators: Variation In Probability Of Pollen Transport Among Insect Taxa, Diane L. Larson, Jennifer L. Larson, Deborah A. Buhl

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

As concern about declining pollinator populations mounts, it is important to understand the range of insect taxa that provide pollination services. We use pollen transport information acquired over three years in two habitats at Badlands National Park, South Dakota, USA, to compare probabilities of pollen transport among insect taxa and between sexes of bees. Sampling was conducted on 1-ha plots, eight in sparse vegetation (May–October samples; N = 74 surveys) and 12 in wheatgrass prairie vegetation (June–July samples; N = 87 surveys). Insects contacting reproductive parts of flowers were netted, placed individually into tubes charged with ethyl acetate, then transferred …


Distance Models As A Tool For Modelling Detection Probability And Density Of Native Bumblebees, Darin J. Mcneil, Clint R. V. Otto, Erin L. Moser, Katherine R. Urban‐Mead, David E. King, Amanda D. Rodewald, Jeffery L. Larkin Jan 2018

Distance Models As A Tool For Modelling Detection Probability And Density Of Native Bumblebees, Darin J. Mcneil, Clint R. V. Otto, Erin L. Moser, Katherine R. Urban‐Mead, David E. King, Amanda D. Rodewald, Jeffery L. Larkin

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Effective monitoring of native bee populations requires accurate estimates of population size and relative abundance among habitats. Current bee survey methods, such as netting or pan trapping, may be adequate for a variety of study objectives but are limited by a failure to account for imperfect detection. Biases due to imperfect detection could result in inaccurate abundance estimates or erroneous insights about the response of bees to different environments. To gauge the potential biases of currently employed survey methods, we compared abundance estimates of bumblebees (Bombus spp.) derived from hierarchical distance sampling models (HDS) to bumblebee counts collected from fixed‐area …

Can The Vaquita Be Saved From Extinction?, Gerardo Rodríguez-Quiroz, Wenceslao Valenzuela-Quiñonez, Héctor A. González-Ocampo, Alfredo Ortega-Rubio

Human–Wildlife Interactions

The vaquita (Phocoena sinus) is considered the world’s most endangered marine mammal. It is the smallest member of the porpoise family endemic to the upper part of the Gulf of California. The current population is estimated at less than 30 individuals. The primary reasons for the species decline includes limited habitat and incidental mortalities associated with illegal gillnet fishing activities. Since 2008, the Mexican government has taken environmental and economic actions to protect the vaquita’s focusing in reducing by-catch deaths to zero. In 2015, a federal Agreement decreed by the Secretaría de Agricultura, Ganadería, Desarrollo Rural, Pesca y …

Searching The Internet To Estimate Deer Population Trends In The U.S., California, And Connecticut, G. Webb Jan 2018

Searching The Internet To Estimate Deer Population Trends In The U.S., California, And Connecticut, G. Webb

Faculty Research, Scholarly, and Creative Activity

Information for decision making may be publicly available, but costly to obtain. As an experiment in environmental scanning, the internet was searched on a daily basis over several years to collect information and provide analysis related to decisions on deer management. The process discovered that, contrary to common assumptions, the U.S. deer population has apparently been falling since about the year 2000 based on analysis of available state data that had not been aggregated. In some cases, state population estimates were created using standard procedures on available data. Results indicate that differences in survey methods appear to be relatively constant …


Of Rats And Men, Thomas S. Walsh Dec 2017

Of Rats And Men, Thomas S. Walsh

Capstones

This capstone is a data-driven investigation into New York City's rat problem. By using publicly available government data to map rat activity in NYC, I identified several socio-economic variables that correlate with rat populations at the community district, borough, and city-scale. I used these findings (mainly that rat problems are linked to lower incomes) as the basis of an investigation, which includes interviews with residents, experts, and city officials. Prof. Bobby Corrigan, urban rodentologist and formerly with the NYC Department of Health criticizes the city's efforts for the first time on the record.

Understanding And Finding Solutions To The Problem Of Sedimentation In The National Wildlife Refuge System, Max Post Van Der Burg, Karen E. Jenni, Timothy L. Nieman, Josh D. Eash, Gregory A. Knutsen Dec 2017

Understanding And Finding Solutions To The Problem Of Sedimentation In The National Wildlife Refuge System, Max Post Van Der Burg, Karen E. Jenni, Timothy L. Nieman, Josh D. Eash, Gregory A. Knutsen

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The National Wildlife Refuge System (Refuge System) is a collection of public lands maintained by the U.S. Fish and Wildlife Service for migratory birds and other wildlife. Wetlands on individual National Wildlife Refuges (Refuges) may be at risk of increased sedimentation because of land use and water management practices. Increased sedimentation can reduce wetland habitat quality by altering hydrologic function, degrading water quality, and inhibiting growth of vegetation and invertebrates. On Refuges negatively affected by increased sedimentation, managers have to address complex questions about how to best remediate and mitigate the negative effects. The best way to account for these …

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Wolves (Canis lupus) and moose (Alces americanus) have been studied since 1958 on 540-squarekilometer Isle Royale National Park, in Lake Superior. Wolves arrived there across the ice around 1949, and the population once increased to about 50, averaging about 25 annually (Mech 1966, Jordan et al. 1967, Vucetich and Peterson 2009). However, for various reasons, wolf numbers there have now dwindled to 2 nonbreeders, and the US National Park Service has proposed reintroducing 20–30 wolves over 3 years (National Park Service 2016). This situation offers an unparalleled opportunity to promote science-based management of this unique national park. …

Community Management And Governance Of Comatsa-Sud New Protected Area (Ambalamanasy Ii Commune), Allison Tennant

Independent Study Project (ISP) Collection

Community-based natural resource management is an increasingly more popular choice for governments to delegate power back to local communities to conserve the resources they rely on. In Madagascar, where much of the rural population provides for their livelihoods by using natural resources, this governance structure, in cooperation with delegated manager for assistance, presents an opportunity for economic development in cooperation with conservation efforts. This paper aims to better understand the role of community, NGO, and governmental actors in creating and executing community management structures. Through Participatory Rural Analysis and structured and semi-structured interviews, it explores what management transfers look like …

Trends In The Environmental Health Job Market For New Graduates, Jason W. Marion, Timothy J. Murphy Phd, Anne Marie Zimeri Phd Sep 2017

Trends In The Environmental Health Job Market For New Graduates, Jason W. Marion, Timothy J. Murphy Phd, Anne Marie Zimeri Phd

EKU Faculty and Staff Scholarship

The question of whether the job market can support future graduates of environmental health programs remains an important and difficult question for environmental health programs, current and prospective students, parents, and other stakeholders. Our previous report using 2014 data from the U.S. Bureau of Labor Statistics demonstrated anticipated growth and higher than average pay in the profession through at least 2022 for baccalaureate degree holders (Marion & Sinde, 2015). Growth in the profession does not necessarily translate into job availability if the market is saturated with job candidates. While university programs produce graduates, local health departments (LHDs) have suffered tremendous …

Do Farm Subsidies Affect Crop Diversification?, Chadwick O'Neal Apr 2017

Do Farm Subsidies Affect Crop Diversification?, Chadwick O'Neal

Georgia College Student Research Events

The United States spends $20 billion each year on farm subsidies. Farmers face increased risk and income variation when their crop portfolio is less diversified. It’s possible for farm subsidies to decrease diversification if they are focused on specific crops. Utilizing state level subsidy and agricultural data from the Environmental Working Group, I used econometric analysis to estimate the effect of farm subsidies on crop diversification. I used the number of acres planted from the 15 top most subsidized and grown crops in the United States to derive my dependent variable, the Herfindahl-Hirschman index (HHI). The HHI is a market …

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 …


The Maine Chance: Private-Public Partnership And The Katahdin Woods And Waters National Monument, Char Miller Apr 2017

The Maine Chance: Private-Public Partnership And The Katahdin Woods And Waters National Monument, Char Miller

Pomona Faculty Publications and Research

The claim of a federal “land grab” in response to the creation of Katahdin Woods and Waters National Monument in Maine revealed a lack of historical awareness by critics of how two other cherished parks were established there: through private-public partnerships and the donation of land by private citizens.
