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 Jan 2016

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 Jan 2016

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

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

Information is sparse about aspects of female wolf (Canis lupus) breeding in the wild, including age of first reproduction, mean age of primiparity, generation time, and proportion of each age that breeds in any given year. We studied these subjects in 86 wolves (113 captures) in the Superior National Forest (SNF), Minnesota (MN), during 1972–2013 where wolves were legally protected for most of the period, and in 159 harvested wolves from throughout MN wolf range during 2012–2014. Breeding status of SNF wolves were assessed via nipple measurements, and wolves from throughout MN wolf range, by placental scars. In …

White-Tailed Deer (Odocoileus Virginianus) Fawn Risk From Gray Wolf (Canis Lupus) Predation During Summer, L. David Mech, Aaron Morris, Shannon M. Barber-Meyer Jan 2015

White-Tailed Deer (Odocoileus Virginianus) Fawn Risk From Gray Wolf (Canis Lupus) Predation During Summer, L. David Mech, Aaron Morris, Shannon M. Barber-Meyer

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

Little is known about how often various prey animals are at risk of predation by Gray Wolves (Canis lupus). We used a system to monitor the presence during the day of two radio-collared Gray Wolves within 2 km of a radio-collared White-tailed Deer (Odocoileus virginianus) with a fawn or fawns in August 2013 in the Superior National Forest of northeastern Minnesota. We concluded that the fawn or fawns were at risk of predation by at least one wolf at least daily.

Yellowstone Wolf (Canis Lupus) Density Predicted By Elk (Cervus Elaphus) Biomass, L. David Mech, Shannon M. Barber-Meyer Jan 2015

Yellowstone Wolf (Canis Lupus) Density Predicted By Elk (Cervus Elaphus) Biomass, L. David Mech, Shannon M. Barber-Meyer

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

The Northern Range (NR) of Yellowstone National Park (YNP) hosts a higher prey biomass density in the form of elk (Cervus elaphus L., 1758) than any other system of gray wolves (Canis lupus L., 1758) and prey reported. Therefore, it is important to determine whether that wolf–prey system fits a long-standing model relating wolf density to prey biomass. Using data from 2005 to 2012 after elk population fluctuations dampened 10 years subsequent to wolf reintroduction, we found that NR prey biomass predicted wolf density. This finding and the trajectory of the regression extend the validity of the model …

Evaluation Of A Formula That Categorizes Female Gray Wolf Breeding Status By Nipple Size, Shannon M. Barber-Meyer, L. David Mech Jan 2015

Evaluation Of A Formula That Categorizes Female Gray Wolf Breeding Status By Nipple Size, Shannon M. Barber-Meyer, L. David Mech

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

The proportion by age class of wild Canis lupus (Gray Wolf) females that reproduce in any given year remains unclear; thus, we evaluated the applicability to our long-term (1972–2013) data set of the Mech et al. (1993) formula that categorizes female Gray Wolf breeding status by nipple size and time of year. We used the formula to classify Gray Wolves from 68 capture events into 4 categories (yearling, adult non-breeder, former breeder, current breeder). To address issues with small sample size and variance, we created an ambiguity index to allow some Gray Wolves to be classed into 2 categories. We …


Gray Wolf (Canis Lupus) Dyad Monthly Association Rates By Demographic Group, Shannon M. Barber-Meyer, L. David Mech Jan 2015

Gray Wolf (Canis Lupus) Dyad Monthly Association Rates By Demographic Group, Shannon M. Barber-Meyer, L. David Mech

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

Preliminary data from GPS-collared wolves (Canis lupus) in the Superior National Forest of northeastern Minnesota indicated wolves had low association rates with packmates during summer. However, aerial-telemetry locations of very high frequency (VHF)-radioed wolves in this same area showed high associations among packmates during winter. We analyzed aerial-telemetry-location data from VHF-collared wolves in several packs (n=18 dyads) in this same area from 1994-2012 by month, and found lowest association rates occurred during June. While other studies have found low association among wolf packmates during summer, information on differences in association patterns depending on the wolf associates’ demographics is …


A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz Jan 2015

A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz

Graduate Student Theses, Dissertations, & Professional Papers

Chile's state designated protected areas are reported to show representation bias and to be unable to meet conservation goals. Private protected areas are considered an important tool to resolve these issues, which has led to support for increasing the role of private protected areas in Chile and creating an integrated public-private protected area network. But the validity of the capacity of private protected areas to fix Chile's state protected area network bias, and the advantage of creating an integrated protected area network, have not been assessed. This study uses the most recent data on Chile's state, private, and international protected …


Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht Nov 2014

Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht

United States National Park Service: Publications

Executive Summary

Agate Fossil Beds National Monument is a 3,057-acre park located in western Nebraska. The unit is comprised of northern mixed-grass prairie vegetation, typical of the Northern Great Plains. Weather, fire, and grazing are generally considered to be the ecological drivers of prairie ecosystems and critical for prairie health. However, grazing has essentially been absent since the 1960s. In 2014, a Department of the Interior report explicitly listed the park as a high priority for bison restoration. This report evaluates the feasibility, management options, benefits, and challenges of restoring bison to Agate Fossil Beds National Monument.

A potential bison …

Anthropology Publications

The most threatened mammal group on Earth, Madagascar’s five endemic lemur families (lemurs are found nowhere else), represent more than 20% of the world’s primate species and 30% of family-level diversity. This combination of diversity and uniqueness is unmatched by any other country—remarkable considering that Madagascar is only 1.3 to 2.9% the size of the Neotropics, Africa, or Asia, the other three landmasses where nonhuman primates occur. But lemurs face extinction risks driven by human disturbance of forest habitats. We discuss these challenges and reasons for hope in light of site-specific, local actions proposed in an emergency conservation action plan.

Successes And Challenges From Formation To Implementation Of Eleven Broad-Extent Conservation Programs, Erik A. Beever, Brady J. Mattsson, Matthew J. Germino, Max Post Van Der Burg, John B. Bradford, Mark W. Brunson

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

Integration of conservation partnerships across geographic, biological, and administrative boundaries is increasingly relevant because drivers of change, such as climate shifts, transcend these boundaries. We explored successes and challenges of established conservation programs that span multiple watersheds and consider both social and ecological concerns. We asked representatives from a diverse set of 11 broadextent conservation partnerships in 29 countries 17 questions that pertained to launching and maintaining partnerships for broad-extent conservation, specifying ultimate management objectives, and implementation and learning. Partnerships invested more funds in implementing conservation actions than any other aspect of conservation, and a program’s context (geographic extent, United …

Federal V. State Effectiveness: An Analysis Of The Endangered Species Act And Current Potential Attempts At Reform, Nicholas Primo Jan 2014

Federal V. State Effectiveness: An Analysis Of The Endangered Species Act And Current Potential Attempts At Reform, Nicholas Primo

Pepperdine Policy Review

In November 2013, several Congressional leaders drafted a new bill to reform the Endangered Species Act of 1973 (ESA). While the Endangered Species Management Self-Determination Act (ESMSDA) was the first major attempt at updating the crucial U.S. environmental policy in decades, it also inflamed environmentalist defenders of the original bill. More importantly, it raised several questions as to whether state or federal-oriented approaches to endangered species protection and environmental policy more broadly is ultimately more effective. This article analyzes the original 1973 ESA, followed by an analysis of the ESMSDA currently being considered. It will discuss the various strengths and …


A Gray Wolf (Canis Lupus) Delivers Live Prey To A Pup, L. David Mech Jan 2014

A Gray Wolf (Canis Lupus) Delivers Live Prey To A Pup, L. David Mech

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

A two-year-old sibling Gray Wolf (Canis lupus) carefully captured an Arctic Hare (Lepus arcticus) leveret alive on Ellesmere Island, Nunavut, Canada, and delivered it alive to a pup 28–33 days old. This appears to be the first observation of a Gray Wolf delivering live prey to a pup.


Sustainability Policy’S Inherent Dilemmas – Exemplified Via Critical Examination Of The Las Vegas Metropolitan Sustainability Campaign, Kathryn A. Zimmerman Jan 2014

Sustainability Policy’S Inherent Dilemmas – Exemplified Via Critical Examination Of The Las Vegas Metropolitan Sustainability Campaign, Kathryn A. Zimmerman

All Master's Theses

In response to a dual problem of critical water scarcity and rapid population growth, leaders of metropolitan Las Vegas implemented a region-wide, internationally marketed sustainability campaign. Preliminary studies found that, while sustainability policy attains its rhetorical goals, solutions initiated not only perpetuate but also purposefully expand the original dual problem to justify continuous water resource acquisitions. To examine this sustainability conundrum constructed by leadership—problem-perpetuation rather than problem-resolution—a critical examination in resource management asked two basic questions: what is being sustained and by what means? Via this inquiry, specific processes by which leaders perpetuate problems can be identified; and, so-informed, new …


Advocacy For Marine Management: Contributions To A Policy Advocacy Initiative In The Maldives, Neal Collins May 2013

Advocacy For Marine Management: Contributions To A Policy Advocacy Initiative In The Maldives, Neal Collins

Capstone Collection

On June 5, 2009 a 42-­‐km2 area of coral reef situated in the Alif Dhaalu (South Ari) atoll of the Republic of Maldives was designated the South Ari Atoll Marine Protected Area (S.A. MPA) due to a globally significant whale shark aggregation site. The whale shark is notorious for its gargantuan size and docile nature, which has led to a burgeoning tourist industry that gives people the opportunity to swim with the gentle giants in tropical sites such as the Maldives. The S.A. MPA receives tens of thousands of visitors a year that engage in whale shark excursions, however, there …

Age Structure Of Moose (Alces Alces) Killed By Gray Wolves (Canis Lupus) In Northeastern Minnesota, 1967–2011, L. David Mech, Michael E. Nelson Jan 2013

Age Structure Of Moose (Alces Alces) Killed By Gray Wolves (Canis Lupus) In Northeastern Minnesota, 1967–2011, L. David Mech, Michael E. Nelson

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

The ages of 77 adult Moose (Alces alces) killed by gray Wolves (Canis lupus) during the period 1967–2011 in northeastern Minnesota were significantly older than those of a sample of 17 585 Moose killed by hunters in nearby Ontario. Our findings support those of earlier studies of protected Moose populations in national parks that found that gray Wolves tend to kill disproportionately more older Moose.

Ocean Governance: The New Zealand Dimension Full Report, Michael Vincent Mcginnis Aug 2012

Ocean Governance: The New Zealand Dimension Full Report, Michael Vincent Mcginnis

Working Papers

The primary goal of this report is to provide interested members of the public and policymakers with a general overview and a description of the types of principles, planning tools, and policy instruments that can be used to strengthen and improve marine governance in New Zealand. As extractive uses (hydrocarbons and minerals, in particular) ramp up and others are explored and brought on line in the marine areas of New Zealand, the need will increase for a more integrative, ecosystem-based approach to marine governance.

This study is based on the following types of analysis:
