United States National Park Service: Publications

Executive Summary

The Northern Great Plains Inventory & Monitoring Network (NGPN) was established to develop and provide scientifically credible information on the current status and long-term trends of the composition, structure, and function of ecosystems in thirteen parks located in five northern Great Plains states. NGPN identified upland plant communities, exotic plant early detection, and riparian lowland communities as vital signs that can be used to better understand the condition of terrestrial park ecosystems (Gitzen et al. 2010). Upland and riparian ecosystems are important targets for vegetation monitoring because the status and trends in plant communities provide critical insights into …

Diversification Or Cotton Recovery In The Malian Cotton Zone: Effects On Households And Women, Jeanne Yekeleya Coulibaly Dec 2011

Diversification Or Cotton Recovery In The Malian Cotton Zone: Effects On Households And Women, Jeanne Yekeleya Coulibaly

INTSORMIL Scientific Publications

This dissertation investigates income diversification alternatives from the cotton economy and compares those initiatives with present policy measures to restore the cotton sector in Mali. It also derives the welfare implications for women of these various policy measures.

During the decade preceding 2011, farmers’ incomes in the cotton zone of Mali have been significantly affected by the downturn of the cotton economy explained by many factors including the low farm gate cotton price, the declining cotton yields and soil fertility concerns. In 2011, the Malian government substantially increased the farm gate cotton price as a result of the world cotton …


Empathy-Based Conservation: An Interdisciplinary Approach To Conservation Policy And Decision-Making, Kaitlyn Delashmutt Dec 2011

Empathy-Based Conservation: An Interdisciplinary Approach To Conservation Policy And Decision-Making, Kaitlyn Delashmutt

Department of Environmental Studies: Undergraduate Student Theses

In the late 20th century, neuroscientists in Italy discovered a neuron in the brain capable of mentally mimicking the emotions derived from the actions of others (Rizzolatti and Craighero, 2004). It is the process that makes your elbow ache when someone else knocks their elbow on the counter or the uncontrollable smile that creeps up when someone smiles at you. No questions asked, people intuitively sense what others are feeling. The old school of thought was that humans deduced through logic and reason the actions of others and interpreted the emotions through a rational process (Carew et al, 2008). …


Agricultural Productivity Growth In Central America And The Caribbean, Ayako Ebata Dec 2011

Agricultural Productivity Growth In Central America And The Caribbean, Ayako Ebata

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This thesis estimates total factor productivity (TFP) growth in the agricultural sector of fourteen regions in Central America and the Caribbean. First, TFP is measured parametrically and non-parametrically, using the Ordinary Least Square (OLS) method and the Maximum Likelihood (ML) method to estimate a translog production function and the Malmquist index approach. Secondly, the thesis incorporates an environmental bad, CO2 emissions from expansion of agricultural land by sacrificing forest area and estimates environmentally adjusted productivity (EAP) growth rates using an output distance function in order to assess how the growth of TFP rates changes when such a bad is …

Coaching Power Tool: Success Vs. Failure, Connie I. Reimers-Hild Sep 2011

Coaching Power Tool: Success Vs. Failure, Connie I. Reimers-Hild

Kimmel Education and Research Center: Faculty and Staff Publications

Part of personal leadership and innovation is self-discovery, which requires introspection and the ability to see the unseen. Sometimes it is necessary to consider a different perspective. We have to shift our thinking to see possibilities in a new light. Sometimes, it is the unobvious that may be the most important. It is important for us to challenge our thinking and traditional thought to redefine success, failure and our ability to take risks.


Factors Controlling Pre-Columbian And Early Historic Maize Productivity In The American Southwest, Part 2: The Chaco Halo, Mesa Verde, Pajarito Plateau/ Bandelier, And Zuni Archaeological Regions, Larry Benson Jun 2011

Factors Controlling Pre-Columbian And Early Historic Maize Productivity In The American Southwest, Part 2: The Chaco Halo, Mesa Verde, Pajarito Plateau/ Bandelier, And Zuni Archaeological Regions, Larry Benson

United States Geological Survey: Staff Publications

Chemical and nutrient analyses of 471 soil samples from 161 sites within four archaeological regions (Pajarito Plateau/Bandelier, Zuni, Mesa Verde, and the Chaco Halo) were combined with historical climate data in order to evaluate the agricultural productivity of each region. In addition, maize productivity and field-life calculations were performed using organic-nitrogen (N) values from the upper 50 cm of soil in each region and a range (1–3%/year) of N-mineralization rates. The endmember values of this range were assumed representative of dry and wet climate states. With respect to precipitation and heat, the Pajarito Plateau area has excellent agricultural potential; the …

Designing A School Garden Space That Emphasizes Children's Wants And Uses Permaculture Design Methods, Mikhaela Mullins May 2011

Designing A School Garden Space That Emphasizes Children's Wants And Uses Permaculture Design Methods, Mikhaela Mullins

Department of Environmental Studies: Undergraduate Student Theses

A case study was organized at Saratoga Elementary school in Lincoln, Nebraska to obtain data on what children desire in a garden space. To collect this data a school garden space was constructed and an after school garden club was implemented. Students who participated in the after school garden club partook in the study by drawing their ideal garden. Elements that the subjects drew were identified and categorized into ‘highly desired’ and ‘somewhat desired’.

These elements were then incorporated into a proposed garden design plan for Saratoga. The proposal plan uses Permaculture design methods to emphasize sustainability.


Replacement Alternatives For Beef Cow Herds: An Analysis Of Retaining Non-Pregnant Cows, Trenton T. Bohling May 2011

Replacement Alternatives For Beef Cow Herds: An Analysis Of Retaining Non-Pregnant Cows, Trenton T. Bohling

Department of Agricultural Economics: Dissertations, Theses, and Student Research

A non-pregnant cow is a liability to a producer. Over the last four years, cow-calf producers have had an increased number of non-pregnant cows due to factors like environmental conditions and diseases like trichomoniasis. While most research has indicated that culling a non-pregnant female and replacing the cow with retained heifers, purchased heifers, or purchased cows are the only economic alternatives, recent trends in the cattle market have suggested that keeping a non-pregnant cow may also be an alternative.

Annual beef cow budgets were created based on typical Nebraska Sandhills conditions. Revenues and costs in these budgets vary according to …

Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen Apr 2011

Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen

Great Plains Research: A Journal of Natural and Social Sciences

Over the past century, the interactions between agricultural land use and government cropland retirement programs have affected pheasant population change. Two government land retirement programs that returned croplands to grasslands, Soil Bank in the 1960s and the current Conservation Reserve Program (CRP), help to illustrate these connections. From 2007 to 2010, South Dakota lost 41% of its CRP lands and experienced an 18% decline in pheasants per mile. However, because of where CRP expirations have occurred and where pheasant populations are found, some regional variability is seen. Western South Dakota (Region 1) had an 80% increase in pheasants per mile …

Confronting Socially Generated Uncertainty In Adaptive Management, Andrew J. Tyre, Sarah Michaels Jan 2011

Confronting Socially Generated Uncertainty In Adaptive Management, Andrew J. Tyre, Sarah Michaels

School of Natural Resources: Faculty Publications

As more and more organizations with responsibility for natural resource management adopt adaptive management as the rubric in which they wish to operate, it becomes increasingly important to consider the sources of uncertainty inherent in their endeavors. Without recognizing that uncertainty originates both in the natural world and in human undertakings, efforts to manage adaptively at the least will prove frustrating and at the worst will prove damaging to the very natural resources that are the management targets. There will be more surprises and those surprises potentially may prove at the very least unwanted and at the worst devastating. We …

Wolves, Canis Lupus, Carry And Cache The Collars Of Radio-Collared White-Tailed Deer, Odocoileus Virginianus, They Killed, Michael E. Nelson, L. David Mech Jan 2011

Wolves, Canis Lupus, Carry And Cache The Collars Of Radio-Collared White-Tailed Deer, Odocoileus Virginianus, They Killed, Michael E. Nelson, L. David Mech

USGS Northern Prairie Wildlife Research Center

Wolves (Canis lupus) in northeastern Minnesota cached six radio-collars (four in winter, two in spring-summer) of 202 radio-collared White-tailed Deer (Odocoileus virginianus) they killed or consumed from 1975 to 2010. A Wolf bedded on top of one collar cached in snow. We found one collar each at a Wolf den and Wolf rendezvous site, 2.5 km and 0.5 km respectively, from each deer’s previous locations.


Use Of Cranial Characters In Taxonomy Of The Minnesota Wolf (Canis Sp.), L. David Mech, Ronald M. Nowak, Sanford Weisberg Jan 2011

Use Of Cranial Characters In Taxonomy Of The Minnesota Wolf (Canis Sp.), L. David Mech, Ronald M. Nowak, Sanford Weisberg

USGS Northern Prairie Wildlife Research Center

Minnesota wolves (Canis sp.) sometimes are reported to have affinity to a small, narrow-skulled eastern form (Canis lupus lycaon Schreber, 1775) and sometimes to a larger, broader western form (Canis lupus nubilus Say, 1823). We found that pre-1950 Minnesota wolf skulls were similar in size to those of wolves from southeastern Ontario and smaller than those of western wolves. However, Minnesota wolf skulls during 1970–1976 showed a shift to the larger, western form. Although Minnesota skull measurements after 1976 were unavailable, rostral ratios from 1969 through 1999 were consistent with hybridization between the smaller eastern wolf and …

Kin Encounter Rate And Inbreeding Avoidance In Canids, Eli Geffen, Michael Kam, Reuven Hefner, Pall Hersteinsson, Anders Angerbjorn, Love Dalen, Eva Fuglei, Karin Noren, Jennifer R. Adams, John Vucetich, Thomas J. Meier, L. David Mech, Bridgett M. Vonholdt, Daniel R. Stahler, Robert K. Wayne

USGS Northern Prairie Wildlife Research Center

Mating with close kin can lead to inbreeding depression through the expression of recessive deleterious alleles and loss of heterozygosity. Mate selection may be affected by kin encounter rate, and inbreeding avoidance may not be uniform but associated with age and social system. Specifically, selection for kin recognition and inbreeding avoidance may be more developed in species that live in family groups or breed cooperatively. To test this hypothesis, we compared kin encounter rate and the proportion of related breeding pairs in noninbred and highly inbred canid populations. The chance of randomly encountering a full sib ranged between 1–8% and …


Parsing Demographic Effects Of Canine Parvovirus On A Minnesota Wolf Population, L. David Mech, Sagar M. Goyal Jan 2011

Parsing Demographic Effects Of Canine Parvovirus On A Minnesota Wolf Population, L. David Mech, Sagar M. Goyal

USGS Northern Prairie Wildlife Research Center

We examined 35 years of relationships among wolf (Canis lupus) pup survival, population change and canine parvovirus (CPV) seroprevalence in northeastern Minnesota to determine when CPV exerted its strongest effects. Using correlation analysis of data from five periods of 7-years each from 1973 through 2007, we learned that the strongest effect of CPV on pup survival (r = -0.73) and on wolf population change (r = -0.92) was during 1987 to 1993. After that, little effect was documented despite a mean CPV seroprevalence from 1994 of 2007 of 70.8% compared with 52.6% during 1987 to 1993. We …


Movements Of Wolves At The Northern Extreme Of The Species’ Range, Including During Four Months Of Darkness, L. David Mech, H. Dean Cluff Jan 2011

Movements Of Wolves At The Northern Extreme Of The Species’ Range, Including During Four Months Of Darkness, L. David Mech, H. Dean Cluff

USGS Northern Prairie Wildlife Research Center

Information about wolf (Canis lupus) movements anywhere near the northern extreme of the species’ range in the High Arctic (.75uN latitude) are lacking. There, wolves prey primarily on muskoxen (Ovibos moschatus) and must survive 4 months of 24 hr/day winter darkness and temperatures reaching 253 C. The extent to which wolves remain active and prey on muskoxen during the dark period are unknown, for the closest area where information is available about winter wolf movements is .2,250 km south. We studied a pack of $20 wolves on Ellesmere Island, Nunavut, Canada (80°N latitude) from July 2009 …


The Scientific Classification Of Wolves: Canis Lupus Soupus, L. David Mech Jan 2011

The Scientific Classification Of Wolves: Canis Lupus Soupus, L. David Mech

USGS Northern Prairie Wildlife Research Center

Gray wolf, timber wolf, red wolf, eastern wolf, brush wolf, arctic wolf, Mexican wolf, maned wolf, Ethiopian wolf, etc., etc. How many kinds of wolves are there? And what are the differences? This is a really good question, and the answer is getting more complicated all the time. Let us start by going back a few years to the way science looked at wolves more traditionally— before the days of the new field of molecular genetics. Molecular genetics examines the actual DNA of animals and tries to classify them according to genetic similarities. ...

Gray Wolf (Canis Lupus) Movements And Behavior Around A Kill Site And Implications For Gps Collar Studies, L. David Mech Jan 2011

Gray Wolf (Canis Lupus) Movements And Behavior Around A Kill Site And Implications For Gps Collar Studies, L. David Mech

USGS Northern Prairie Wildlife Research Center

Global Positioning System (GPS) radio-collars are increasingly used to estimate Gray Wolf (Canis lupus) kill rates. In interpreting results from this technology, researchers make various assumptions about wolf behavior around kills, yet no detailed description of this behavior has been published. This article describes the behavior of six wolves in an area of constant daylight during 30 hours, from when the pack killed a Muskox (Ovibos moschatus) calf and yearling on Ellesmere Island, Nunavut, Canada, to when they abandoned the kill remains. Although this is only a single incident, it demonstrates one possible scenario of pack …

Infectious Diseases In Yellowstone’S Canid Community, Emily S. Almberg, Paul C. Cross, L. David Mech, Doug W. Smith, Jennifer W. Sheldon, Robert L. Crabtree

USGS Northern Prairie Wildlife Research Center

Each summer Yellowstone Wolf Project staff visit den sites to monitor the success of wolf reproduction and pup rearing behavior. For the purposes of wolf monitoring, Yellowstone National Park (YNP) is divided into two study areas, the northern range and the interior, each distinguished by their ecological and physiographical differences. The 1,000 square kilometer northern range, characterized by lower elevations (1,500–2,200 m), serves as prime winter habitat for ungulates and supports a higher density of wolves than the interior (20–99 wolves/1,000 km2 versus 2–11 wolves/1,000 km2). The interior of the park encompasses 7,991 square kilometers, is higher …
