Assessing Factors That May Predispose Minnesota Farms To Wolf Depredations On Cattle, L. David Mech, Elizabeth K. Harper, Thomas J. Meier, William J. Paul Jan 2000

Assessing Factors That May Predispose Minnesota Farms To Wolf Depredations On Cattle, L. David Mech, Elizabeth K. Harper, Thomas J. Meier, William J. Paul

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

Wolf (Canis lupus) depredations on livestock cause considerable conflict and expense in Minnesota. Furthermore, claims are made that such depredations are fostered by the type of animal husbandry practiced. Thus, we tried to detect factors that might predispose farms in Minnesota to wolf depredations. We compared results of interviews with 41 cattle farmers experiencing chronic cattle losses to wolves (chronic farms) with results from 41 nearby "matched" farms with no wolf losses to determine farm characteristics or husbandry practices that differed and that therefore might have affected wolf depredations. We also used a Geographic Information System (GIS) to …


Megapodes Status Survey And Conservation Action Plan, 2000-2004, René W. R. J. Dekker, Richard A. Fuller, Gilliam C. Baker, World Pheasant Association, Birdlife International, Iucn-Ssc Megapode Specialist Group Jan 2000

Megapodes Status Survey And Conservation Action Plan, 2000-2004, René W. R. J. Dekker, Richard A. Fuller, Gilliam C. Baker, World Pheasant Association, Birdlife International, Iucn-Ssc Megapode Specialist Group

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

Executive Summary

This Action Plan covers the megapodes, a group of Australasian ground-dwelling birds comprising 22 species found from the Nicobar Islands in the west, through Indonesia, the Philippines, and Australia, to Polynesia in the east. Their habit of nesting on or near beaches, often on small islands, makes them vulnerable to disturbance and egg collecting, and several species are greatly threatened. In 1995, the first Action Plan for the conservation of these species was published and this document provides an update on the current situation. The objectives of this document are to identify the most threatened species within this …


Proximity Of White-Tailed Deer, Odocoileus Virginianus, Ranges To Wolf, Canis Lupus, Pack Homesites, Michael E. Nelson, L. David Mech Jan 2000

Proximity Of White-Tailed Deer, Odocoileus Virginianus, Ranges To Wolf, Canis Lupus, Pack Homesites, Michael E. Nelson, L. David Mech

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

Seven adult female White-tailed Deer (Odocoileus virginianus) in northeastern Minnesota lived within 1.8 km of Wolf pack (Canis lupus) homesites without vacating their home ranges. Six of these deer and at least three of their fawns survived through the Wolf homesite period.


A Record Large Wolf, Canis Lupus, Pack In Minnesota, L. David Mech Jan 2000

A Record Large Wolf, Canis Lupus, Pack In Minnesota, L. David Mech

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

This report documents a pack of 22-23 Wolves (Canis lupus) in central Minnesota. This is larger than the largest pack previously observed on the mainland in the midwestern U.s. during 650 wolf pack-years. Because this record-large pack preyed on White-tailed Deer (Odocoileus virginianus), one of the Wolfs smaller prey, it is evidence that pack size and prey size are not tightly related. It also indicates the size that Wolf packs can attain in the area if fully protected from human persecution.


Lack Of Reproduction In Muskoxen And Arctic Hares Caused By Early Winter?, L. David Mech Jan 2000

Lack Of Reproduction In Muskoxen And Arctic Hares Caused By Early Winter?, L. David Mech

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

A lack of young muskoxen (Ovibos moschatus) and arctic hares (Lepus arcticus) in the Eureka area of Ellesmere Island, Northwest Territories (now Nunavut), Canada, was observed during summer 1998, in contrast to most other years since 1986. Evidence of malnourished muskoxen was also found. Early winter weather and a consequent 50% reduction of the 1997 summer replenishment period appeared to be the most likely cause, giving rise to a new hypothesis about conditions that might cause adverse demographic effects in arctic herbivores.

Accuracy And Precision Of Estimating Age Of Gray Wolves By Tooth Wear, Philip S. Gipson, Warren B. Ballard, Ronald M. Nowak, L. David Mech Jan 2000

Accuracy And Precision Of Estimating Age Of Gray Wolves By Tooth Wear, Philip S. Gipson, Warren B. Ballard, Ronald M. Nowak, L. David Mech

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

We evaluated the accuracy and precision of tooth wear for aging gray wolves (Canis lupus) from Alaska, Minnesota, and Ontario based on 47 known-age or known-minimum-age skuIIs. Estimates of age using tooth wear and a commercial cementum annuli-aging service were useful for wolves up to 14 years old. The precision of estimates from cementum annuli was greater than estimates from tooth wear, but tooth wear estimates are more applicable in the field. We tended to overestimate age by 1-2 years and occasionaIIy by 3 or 4 years. The commercial service aged young wolves with cementum annuli to within …


Prolonged Winter Undernutrition And The Interpretation Of Urinary Allantoin:Creatinine Ratios In White-Tailed Deer, Glenn D. Delgiudice, Ken D. Kerr, L. David Mech, Ulysses S. Seal Jan 2000

Prolonged Winter Undernutrition And The Interpretation Of Urinary Allantoin:Creatinine Ratios In White-Tailed Deer, Glenn D. Delgiudice, Ken D. Kerr, L. David Mech, Ulysses S. Seal

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

The urinary allantoin:creatinine (A:C) ratio (expressed in micromoles of allantoin to micromoles of creatinine) has shown potential as an index of recent winter energy intake in preliminary controlled studies of elk (Cervus elaphus) involving mild condition deterioration (up to 11% loss of body mass). To ensure reliable nutritional assessments of free-ranging cervids by measuring A:C ratios of urine in snow, it is essential to extend this work. We assessed the effect of moderate and severe winter nutritional restriction on urinary A:C ratios of captive white-tailed deer (Odocoileus virginianus) that lost up to 32% body mass and …

Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials

Executive Summary

This Action Plan covers the pheasants, a group of one African species and 50 Asian ground-dwelling birds, found within Asia from the Caucasus in the west, through the Indian Subcontinent and the Himalayas to eastern China and Japan. They also occur through Southeast Asia to Flores, east of Java. They are largely dependent on forested habitats, making them highly vulnerable to deforestation and habitat degradation. As large, ground-dwelling birds they are also widely hunted for food, plumage, and the live bird trade. Consequently, many species are threatened. The first version of this Action Plan was published to cover …

Alpha Status, Dominance, And Division Of Labor In Wolf Packs, L. David Mech Jan 1999

Alpha Status, Dominance, And Division Of Labor In Wolf Packs, L. David Mech

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

The prevailing view of a wolf (Canis lupus) pack is that of a group of individuals ever vying for dominance but held in check by the “alpha” pair, the alpha male and alpha female. Most research on the social dynamics of wolf packs, however, has been conducted on non-natural assortments of captive wolves. Here I describe the wolf-pack social order as it occurs in nature, discuss the alpha concept and social dominance and submission, and present data on the precise relationships among members in free-living packs, based on a literature review and 13 summers of observations of wolves …

Regurgitative Food Transfer Among Wild Wolves, L. David Mech, Paul C. Wolf, Jane M. Packard Jan 1999

Regurgitative Food Transfer Among Wild Wolves, L. David Mech, Paul C. Wolf, Jane M. Packard

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

Few studies of monogamous canids have addressed regurgitation in the context of extended parental care and alloparental care within family groups. We studied food transfer by regurgitation in a pack of wolves on Ellesmere Island, North West Territories, Canada, during 6 summers from 1988 through 1996. All adult wolves, including yearlings and a post-reproductive female, regurgitated food. Although individuals regurgitated up to five times per bout, the overall ratio of regurgitations per bout was 1.5. Pups were more likely to receive regurgitations (81%) than the breeding female (14%) or auxiliaries (6%). The breeding male regurgitated mostly to the breeding female …

Twenty-Year Home-Range Dynamics Of A White-Tailed Deer Matriline, Michael E. Nelson, L. D. Mech Jan 1999

Twenty-Year Home-Range Dynamics Of A White-Tailed Deer Matriline, Michael E. Nelson, L. D. Mech

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

We examined the seasonal migration and home-range dynamics of a multigeneration white-tailed deer (Odocoileus virginianus) matriline comprising six females from four generations spanning a 20-year period in northeastern Minnesota. All, from the matriarch to her great-granddaughter, migrated to the same summer and winter ranges, the longest individual record being 14.5 years. Three maternal females concurrently occupied exclusive fawning sites within their ancestral matriarch’s summer range, while two nonmaternal females explored new areas and ranged near their mothers. One great-granddaughter expanded her summer range 1 km beyond the matriarch’s summer range while essentially vacating half of her ancestors’ range …

Why Targets Of Regulations Do Not Comply: The Case Of Conservation Compliance In The Corn Belt, J. Dixon Esseks, Steven E. Kraft, Edward J. Furlong Aug 1997

Why Targets Of Regulations Do Not Comply: The Case Of Conservation Compliance In The Corn Belt, J. Dixon Esseks, Steven E. Kraft, Edward J. Furlong

Center for Great Plains Studies: Staff and Fellows Publications

This article employs survey data to test hypotheses about Corn Belt farmers’ intentions to apply conservation compliance plans. The data came from winter 1995 telephone interviews with a random sample of 839 farmers in that five-state region who had USDA-approved plans for their high4 erodible cropland For ethical and practical reasons noncompliance was measured indirectly-the respondents’ estimates of the percentage of their peers in the county who would “not apply their plans to any meaningful extent in 1995.” Regression analysis found that, as predicted by deterrence theory, farmers who believed in high probabilities of violations being detected or penalized were …
