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 …

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 …

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. …

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 …

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 …

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. This article discusses …

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 …

Resilience Theory In Climate-Based Agriculture Development Projects: Useful Framework Or Popular Buzzword?, Rebecca Ann Chillrud

Bard Center for Environmental Policy

International development organizations are increasingly attempting to improve the resilience of the communities they serve through their projects in these communities. However, these projects often fail to address key concepts from the resilience theory literature, calling into question their ability to effectively promote resilience. This thesis attempts to locate these gaps in understanding by analyzing proposal documents from projects intending to promote agricultural resilience to climate change. A content analysis approach was used to analyze 55 projects from three international development groups—the Global Environment Facility, the World Bank, and the United Nations Development Program—proposed or completed between 2006 and 2016. …

Sandhill Crane Roost Selection, Human Disturbance, And Forage Resources, Aaron T. Pearse, Gary L. Krapu, David A. Brandt

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

Sites used for roosting represent a key habitat requirement for many species of birds because availability and quality of roost sites can influence individual fitness. Birds select roost sites based on numerous factors, requirements, and motivations, and selection of roosts can be dynamic in time and space because of various ecological and environmental influences. For sandhill cranes (Antigone canadensis) at their main spring staging area along the Platte River in south-central Nebraska, USA, past investigations of roosting cranes focuse donphysical channel characteristics related to perceived security as motivating roost distribution.We used 6,310 roost sites selected by 313 sandhill cranes over …

Agenda: Flpma Turns 40, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

FLPMA Turns 40 (October 21)

The Bureau of Land Management (BLM) administers approximately 245 million acres of our public lands and yet, for most of our nation's history, these lands seemed largely destined to end up in private hands. Even when the Taylor Grazing Act of 1934 ushered in an important era of better managing public grazing districts and "promoting the highest use of the public lands," such use of our public lands still was plainly considered temporary, "pending its final disposal." It was not until 1976 with the passage of the Federal Land Policy and Management Act (FLPMA) that congress adopted a policy that …

Plastic Pollution And The Global Throwaway Culture: Environmental Injustices Of Single-Use Plastic, Kristin L. Mcdermott

ENV 434 Environmental Justice

The global throwaway culture has created a cross-ecosystem plastic pollution injustice. The first to suffer this injustice will be the most vulnerable. Our oceans have become our dumpsters. The throwaway culture has created a disrespect of material goods that has turned the earth’s resources into rubbish after a single use. Eighty percent of the yearly 8 million tons of plastic that enter the ocean is single use plastic, such as plastic bottles, plastic shopping bags, or cigarette lighters.[1] Plastic has destroyed ecosystems, robbing impoverished communities of natural resources and of a healthy and safe living environment.

Patuxent’S Long-Term Research On Wolves, L. David Mech

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

The gray wolf (Canis lupus) was one of the first species placed on the Endangered Species List in 1967. The Endangered Species Act of 1973 legally protected the wolf along with other listed species.

Patuxent Wildlife Research Center (Patuxent) in Laurel, MD, began its Endangered Wildlife Program in 1966, and U.S. Fish and Wildlife Service (USFWS) biologist Ray Erickson was assigned to lead it. In 1973, I was transferred to the program from Region 3 of the USFWS, having been employed there since 1969 to study wolves in Minnesota.

Territoriality And Inter-Pack Aggression In Gray Wolves: Shaping A Social Carnivore's Life History Rudyard Kipling's Law Of The Jungle Meets Yellowstone's Law Of The Mountains, Kira A. Cassidy, Douglas W. Smith, L. David Mech, Daniel R. Macnulty, Daniel R. Stahler, Matthew C. Metz

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

When Rudyard Kipling wrote The Jungle Book in 1894 and included the famous line "For the strength of the Wolf is the Pack, and the strength of the Pack is the Wolf," he would have had no idea that over a century later, scientific research would back up his poetic phrase. Recent studies in Yellowstone have found that both the individual wolf and the collective pack rely on each other and play important roles in territoriality. At a time when most fairy tales and fables were portraying wolves as demonic killers or, at best, slapstick gluttons, Kipling seemed to have …

Wolf (Canis Lupus) Generation Time And Proportion Of Current Breeding Females By Age, L. David Mech, Shannon M. Barber-Meyer, John Erb
