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 …

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

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 …

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

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

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

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 …

Traditional medicine is an important aspect of the both the culture and health of communities worldwide. Ngezi Forest Reserve is a protected area on Pemba Island which is part of the Zanzibar Archipelago. This forest contains a wealth of botanical diversity which includes many species of medicinal plants. Traditional healers (waganga) use these medicinal plants to heal members of the community. Interviews and forest walks with these healers were supplemented by consultations with a botanist to determine medicinal value of the forest and the surrounding areas. In compiling information from 15 healers in the area, 98 species of medicinal plants …

An Unparalleled Opportunity For An Important Ecological Study, L. David Mech, Shannon M. Barber-Meyer, Juan Carlos Blanco, Luigi Boitani, Ludwig Carbyn, Glenn Delgiudice, Steven H. Fritts, Djuro Huber, Olof Liberg, Brent Patterson, Richard R. Thiel

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 …

A Study Of Reptile Community Diversity Related To Habitat Characteristics At Marojejy National Park, Julia Kowala

Independent Study Project (ISP) Collection

Marojejy National Park is known for its diversity. Though it is home to the silky sifaka, it has extensive populations of herpetofauna. Seventy-seven species of reptiles have been documented in Marojejy National Park. This study aimed to evaluate the reptile community diversity and habitat characteristics in the park through systematic searches of ten-by-ten-meter plots, and inventory of species as they were found throughout the park. Systematic searches yielded the finding of 19 of the total 25 species identified. Some species that were found had not been previously seen at Marojejy before, most notably, Brookesia sp. “Nosy Hara”, Brookesia desperata, Furcifer …

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

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 …

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

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.

Homestead National Monument Of America, Bat Acoustic Monitoring, September 2016, Daniel S. Licht

United States National Park Service: Publications

Abstract

Homestead National Monument of America is a 211-acre park located in an agrarian landscape in southeastern Nebraska. From September 16 to October 1, 2016, park staff deployed acoustic monitors at three sites in the park for purposes of monitoring night-time bat activity. The three sites averaged 179, 48, and 33 bat detections per night. Night-time bat activity was generally highest in the 1-2 hours following sunset.

Based on the acoustic surveys the big brown (Eptesicus fuscus), eastern red (Lasiurus borealis), northern long-eared (Myotis septentrionalis) and evening bats (Nycticeius humeralis) were present at the …

Where Can Wolves Live And How Can We Live With Them?, L. David Mech

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

In the contiguous 48 United States, southern Canada, and in Europe, wolves (Canis lupus) have greatly increased and expanded their range during the past few decades.They are prolific, disperse long distances, readily recolonize new areas where humans allow them, and are difficult to control when populations become established.Because wolves originally lived nearly everywhere throughout North America and Eurasia, and food in the form of wild and domestic prey is abundant there, many conservation-minded people favor wolves inhabiting even more areas.On the other hand, wolves conflict in several ways with rural residents who prefer fewer wolves.

Carbon Stocks In Shade Coffee: Strategies For Enhancing Carbon Storage In Smallholder Systems In Jinotega, Nicaragua, Vanessa Katheryn Kichline

Bard Center for Environmental Policy

Climate change has recently shifted focus to adaptation and mitigation strategies in coffee production. Shade coffee systems, already widely recognized for their contribution to biodiversity and soil conservation, are now drawing attention for their role in carbon storage. Researchers have generally assumed that high carbon storage must come at the expense of reduced crop yields, implying that farmers must choose between sustainability and profit. This study uses field inventories of 70 farms in Jinotega, Nicaragua to estimate this tradeoff in smallholder shade coffee systems. Field inventories were used to develop three typologies representing different shade management strategies in use in …

Addressing Antibiotic Resistance From Farm-Raised Fish Imported To The United States, Nicholas Ali

Bard Center for Environmental Policy

Misuse of medically important antibiotics in animal production threatens the effectiveness of drugs that are vital in combating disease and infections. Recently, the FDA implemented regulations to limit the use of and access to veterinary drugs. However, these regulations only affect domestic production operations. Because over 90% of seafood consumed in the U.S. is imported from countries with different regulatory standards and because the U.S. has an import inspection rate of less than 1%, antibiotic resistance stemming from imported aquaculture is still a risk that is not sufficiently accounted for. This research investigates how the U.S. has reacted to the …
