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.

Durant l’été 1998, et ce, à la différence de la plupart des années depuis …


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 …


Oxidative Stress Resistance: A Robust Correlated Response To Selection In Extended Longevity Lines Of Drosophila Melanogaster?, Lawrence G. Harshman, Beth A. Haberer Jan 2000

Oxidative Stress Resistance: A Robust Correlated Response To Selection In Extended Longevity Lines Of Drosophila Melanogaster?, Lawrence G. Harshman, Beth A. Haberer

Lawrence G. Harshman Publications

Stress resistance is associated with longevity in Drosophila melanogaster and other model organisms used for genetic research. The present study tests for oxidative stress resistance in one set of lines selected for late-life reproduction and extended longevity. Both females and males from the selected lines were appreciably more resistant to oxidative stress than were flies from the control lines. A relative increase in oxidative stress resistance is a correlated response to selection in this laboratory selection experiment. Increased oxidative stress resistance appears to be a relatively robust correlated response to laboratory selection for late-life reproduction and extended longevity.


Recognition Of Treponematoses In Post Repatriation X Ray And Cd Rom Nebraska Record, Karl J. Reinhard, Bruce Rothschild, Christine Rothschild, Larry Martin Jan 2000

Recognition Of Treponematoses In Post Repatriation X Ray And Cd Rom Nebraska Record, Karl J. Reinhard, Bruce Rothschild, Christine Rothschild, Larry Martin

Karl Reinhard Publications

Repatriation has compromised the opportunity to directly examine skeletons and to apply new diagnostic criteria and techniques. Pre-repatriation approaches to non-metric data acquisition, must make a number of assumptions: ( I ) Phenomena must be correctly identitied and segregated; (2) Criteria for severity must be specific to the phenomena studied; and (3) As criteria for disease rewgnition may change with time, it is valuable only as long as the raw data is also recorded. As part of data preservation, x-rays and CD-ROM images were recorded for skeletons trom Nebraska sites undergoing repatriation. This report concentrates on four of them 250K …


The Role Of Mummy Studies In Paleoparasitology, Adauto Araujo, Karl J. Reinhard, Luiz Fernando Ferreira Jan 2000

The Role Of Mummy Studies In Paleoparasitology, Adauto Araujo, Karl J. Reinhard, Luiz Fernando Ferreira

Karl Reinhard Publications

Paieoparasitology has advance during the past decade to the status of a statistically based science focused on problems of disease ecology and geographic distribution of parasitism. For most of its development, paleoparasitology has focused on the analysis of coprolites and latrine sediments. During the past few years, mummies have been increasingly included in paleoparasitology studies. We evaluate in this paper the interpretive value of mummies relative to other sources of paleoparasitological data.

Archaeoparasitology, Karl Reinhard Jan 2000

Archaeoparasitology, Karl Reinhard

Karl Reinhard Publications

The field devoted to the identification of parasite remains in the archaeological record and the reconstruction of past human-parasite interactions. Parasitic disease has always been a major problem. Recent summaries of the prevalence of parasitic diseases in the world today show that there are 4.5 billion infections with all species of parasitic worm, 1 billion infections with giant intestinal roundworm (Ascaris lumbricoides), 750,000,000 infections with whipworms (Trichuris trichiura), 900,000,000 infections with hookworm (Ancylostoma duodenale and Necator americanus), 657,000,000 infections with filarial worms, 200,000,000 with blood flukes (schistosome species), and 489,000,000 infections with malaria. These infections cause between 1,590,000 to 3,130,000 …


Coprolite Analysis: The Analysis Of Ancient Human Feces For Dietary Data, Karl Reinhard Jan 2000

Coprolite Analysis: The Analysis Of Ancient Human Feces For Dietary Data, Karl Reinhard

Karl Reinhard Publications

Although archaeological fieldwork is hot and dirty, the most “earthy” side of the discipline is the laboratory analysis of coprolites. Each coprolite contains the remains of one to several actual meals eaten in prehistory, and analysis of many coprolites provides a picture of ancient diet that is unique in accuracy.

The term coprolite originally referred to fossilized feces in paleontological context. In archaeology, the term broadened to refer to any formed fecal mass, including mineralized, desiccated, or frozen feces and even the intestinal contents of mummies. Coprolites contain the remains of animals (parasites) that lived in the humans, the foods …


Paleopharmacology, Karl Reinhard Jan 2000

Paleopharmacology, Karl Reinhard

Karl Reinhard Publications

An emerging field devoted to the exploration of the archaeological record for evidence of medicinal plants.

In the future, archaeology will have a role in pharmaceutical research. In the late twentieth century, much of the world’s pharmaceutical research has been based on ethnographic documentation of tribally recognized medicinal plants. Once the active chemical compounds in the plants are identified, they are either extracted or synthesized for commercial use. The American film Medicine Man depicts this approach. As shown in the film, such pharmacological research is threatened by declining tribal populations with loss of traditional herbal knowledge coupled with declining biodiversity. …

Growth And Performance Of Broiler Chicks During The Starter And Grower Phases In Phase-Feeding, L. Niki Loupe, Jason L. Emmert Jan 2000

Growth And Performance Of Broiler Chicks During The Starter And Grower Phases In Phase-Feeding, L. Niki Loupe, Jason L. Emmert

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

An experiment was conducted to evaluate the efficacy of a nutrition program referred to as “phase-feeding” (PF) over the first 6 weeks posthatching. Diets were formulated using amino acid recommendations from the National Research Council (NRC) (1994) or from linear regression equations generated from best estimates of lysine (Lys), sulfur amino acid (SAA), and threonine (Thr) requirements. Regression equations were used to predict weekly Lys, SAA, and Thr requirements for use in a PF regimen that involved lowering amino acid levels following each respective week of the experiment, resulting in six diets fed over the 6-week period. Over the entire …

Relation Between Internal Parasites With Basic Services And The Nutritional Status Of Children Five Years Of Age In The Indigenous, Black And Mestizo Communities Of The Rural Area, Imbabura Province, R. Patricio Paguay Ruiz Jan 2000

Relation Between Internal Parasites With Basic Services And The Nutritional Status Of Children Five Years Of Age In The Indigenous, Black And Mestizo Communities Of The Rural Area, Imbabura Province, R. Patricio Paguay Ruiz

Theses and Dissertations

Various studies have been done to determine the prevalence of anemia in our country, but these studies don't reflect the true magnitude of this sickness, considered in Ecuador a problem of public health since these investigations correspond to urban sectors and margins and not to rural places where the care is very deficient and in certain cases useless, mainly because of the difficult access and the lack of economic resources of the government institutions. The current work was realized in coordination with the school of Nutrition and Dietetics and with the help of the Benson Agriculture and Food Institute was …

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 …

Feasibility Of Inducing Overlap Immunologic Competence In Gallinaceous Birds With Ascardia Dissimilis And A. Galli, Julie Hamilton, Thomas A. Yazwinski

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Chickens and turkeys are routinely infected with the roundworms Ascaridia galli and A. dissimilis, respectively. The current study was conducted to gather basic information on these worms and to determine whether heterologous infections (chicken worms in turkeys and turkey worms in chickens) would be successful. Chickens and turkeys were obtained at day of hatch, brooded to 7 days of age, and placed in pens (25/pen) according to infection as received at 7 days of age: homologous, heterologous and control (no infection). Bird weights, mortalities, and feed efficiencies were monitored for 3 weeks postinfection, at which time all birds were killed …

Policy For Integrated Solid Waste Management In Malaysia, Dennis Jeyakumar

Student Works (2000-2009)

Solid waste management problems have been gaining prominence in Malaysia due to increasing waste generation and the ineffectiveness of the existing mechanism to tackle the problem holistically. This study seeks to formulate a policy for Integrated Solid Waste Management (ISWM) in Malaysia. This has been done by reviewing the legislative and institutional framework as well as the existing practices and trends in Malaysia. Based on this, key issues and needs of solid waste management in Malaysia have been derived. These key issues were then used as a basis to formulate policy instruments to achieve the main objective of ISWM in …

Cytotoxic T Cell Response To Influenza Vaccination In Older Adults, Caroline R. Letter Jan 2000

Cytotoxic T Cell Response To Influenza Vaccination In Older Adults, Caroline R. Letter

Chemistry & Biochemistry Theses & Dissertations

Influenza infections result in activation of cellular and humoral immune responses, leading to stimulation of cytotoxic T cells (CTL) and helper T cells with subsequent viral clearance.

By using an assay of granzyme B activity, the in vivo cellular-mediated immune response of old adults was found to be significantly decreased in comparison to young adults. The effect of aging on the CTL response was further investigated via enzyme-linked immunospot technique. A significant increase in number of virus-specific T cells occurred in older adults after vaccination, although the magnitude of the CTL response decreased in comparison to young adults. These data …


A Preliminary Investigation Of The Construct Of Psychopathic Personality (Psychopathy) In Chimpanzees (Pan Troglodytes), Scott O. Lilienfeld, Jonathan Gershon, Marshall Duke, Lori Marino, Frans B. M. De Waal Dec 1999

A Preliminary Investigation Of The Construct Of Psychopathic Personality (Psychopathy) In Chimpanzees (Pan Troglodytes), Scott O. Lilienfeld, Jonathan Gershon, Marshall Duke, Lori Marino, Frans B. M. De Waal

Sentience Collection

Although the construct of psychopathy has received considerable attention in humans, its relevance to other animals is largely unknown. We developed a measure of psychopathy for use in chimpanzees (Pan troglodytes), the Chimpanzee Psychopathy Measure (CPM), and asked 6 raters to complete this index on 34 chimpanzees. The CPM (a) demonstrated satisfactory interrater reliability and internal consistency; (b) exhibited marginally significant sex differences (males > females); (c) correlated positively with measures of extraversion, agreeableness, and observational ratings of agonism, sexual activity, daring behaviors, teasing, silent bluff displays, and temper tantrums, and negatively with observational ratings of generosity; and (d) demonstrated incremental …


Social Mechanisms Enhance Escape Responses In Shoals Of Rainbowfish, Melanotaenia Duboulayi, Culum Brown, Kevin Warburton Dec 1999

Social Mechanisms Enhance Escape Responses In Shoals Of Rainbowfish, Melanotaenia Duboulayi, Culum Brown, Kevin Warburton

Aquaculture Collection

Shoaling behaviour has been shown to provide many benefits to group members. In this study we examined the ability of fish shoals to escape from a novel trawl apparatus. Fish in shoals of 5 found, and escaped through, a hole in the oncoming trawl more quickly than fish in pairs. Fish in the larger shoals displayed a significant decrease in escape latencies over a series of five trawls, providing clear evidence of net avoidance learning, whereas fish in pairs showed no evidence of learning over successive runs. Observations suggested that more information on the location of the escape route was …

Scale-Model Comprehension By Chimpanzees (Pan Troglodytes), Valerie A. Kuhlmeier, Sarah T. Boysen, Kimberly L. Mukobi

Sentience Collection

The ability of chimpanzees (Pan troglodytes) to recognize the correspondence between a scale model and its real-world referent was examined. In Experiments 1 and 2, an adult female and a young adult male watched as an experimenter hid a miniature model food in 1 of 4 sites in a scale model. Then, the chimpanzees were given the opportunity to find the real food item that had been hidden in the analogous location in the real room. The female performed significantly above chance, whereas the male performed at chance level. Experiments 3 and 4 tested 5 adult and 2 adolescent chimpanzees …


Overall Animal Welfare Assessment Reviewed. Part 1: Is It Possible?, M.B.M. Bracke, B. M. Spruijt, J.H.M. Metz Dec 1999

Overall Animal Welfare Assessment Reviewed. Part 1: Is It Possible?, M.B.M. Bracke, B. M. Spruijt, J.H.M. Metz

Assessment of Animal Welfare Collection

Several authors have concluded that scientists should not attempt to perform overall animal welfare assessment (OWA). They argue that scientists have continued to fail to make progress in this area and that value judgements are inherently involved in OWA for which science cannot provide answers. We take a more positive attitude toward OWA and argue that scientists should avoid creating a self-fulfilling prophecy. OWA is necessary for making actual moral and political decisions. Science has already accumulated much relevant information about welfare and this information should be applied in decision making.

The task of OW A is to assess welfare …

Overall Animal Welfare Reviewed. Part 2: Assessment Tables And Schemes, M.B.M. Bracke, J.H.M. Metz, B. M. Spruijt

Assessment of Animal Welfare Collection

In the scientific literature several attempts have been made to systematically assess the overall welfare-status of animals in relation to housing and management. This paper reviews assessment tables and schemes that have been constructed to this end. These tables and schemes have a tabular format that allows an assessment of housing systems using a list of welfare-relevant attributes (properties of the housing system). Rather than identifying deficits, the focus of this review is on finding positive recommendations for the purpose of developing a method for overall welfare assessment (OWA) on a scientific basis. The main recommendation is to use the …


Overall Animal Welfare Reviewed. Part 3: Welfare Assessment Based On Needs And Supported By Expert Opinion, M.B.M. Bracke, B. M. Spruijt, J.H.M. Metz Dec 1999

Overall Animal Welfare Reviewed. Part 3: Welfare Assessment Based On Needs And Supported By Expert Opinion, M.B.M. Bracke, B. M. Spruijt, J.H.M. Metz

Assessment of Animal Welfare Collection

Welfare concerns what matters to animals from their point of view. What matters to animals is their state of need. Satisfaction and frustration of needs are associated with emotional states, the subjective experience of which directly determines the welfare status of an animal. Because emotional states are difficult to assess, overall welfare assessment (OWA) is best approached as an assessment of needs.

For actual OW A a list of needs must be formulated. Different authors have formulated different lists. From these lists a concept need-list was constructed. For validation the needs-based approach for OWA was discussed in interviews with experts …


Fisheries Research Report No. 117 - A 12-Month Survey Of Coastal Recreational Boat Fishing Between Augusta And Kalbarri On The West Coast Of Western Australia During 1996-97, Neil R. Sumner, Peta C. Williamson Dec 1999

Fisheries Research Report No. 117 - A 12-Month Survey Of Coastal Recreational Boat Fishing Between Augusta And Kalbarri On The West Coast Of Western Australia During 1996-97, Neil R. Sumner, Peta C. Williamson

Fisheries Research Reports

A creel survey of recreational boat-based fishers on the west coast of Western Australia was conducted from September 1996 to August 1997 to provide information required by fisheries managers. The bus route method, where a survey interviewer visits all boat ramps in a district on the one day, was used. The time spent fishing, catch, demographic and attitudinal information was collected from boat crews returning to boat ramps at the completion of a fishing trip. The total marine catch (number of fish kept) was estimated for key recreational species. Whiting species (other than King George whiting) (564,000) and Australian herring …
