Leadership In Wolf, Canis Lupus, Packs, L. David Mech

USGS Northern Prairie Wildlife Research Center

I examine leadership in Wolf (Callis lupus) packs based on published observations and data gathered during summers from 1986 to 1998 studying a free-ranging pack of Wolves on Ellesmere Island that were habituated to my presence. The breeding male tended to initiate activities associated with foraging and travel, and the breeding female to initiate, and predominate in, pup care and protection. However, there was considerable overlap and interaction during these activities such that leadership could be considered a joint function. In packs with multiple breeders, quantitative information about leadership is needed.

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

USGS Northern Prairie Wildlife Research Center

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 …

Dc Birdscape: A Program For Monitoring Neotropical Migratory Birds In Washington, Dc, John Sauer, John Hadidian, Sam Droege, Paul Handly, Carolyn Williams, Christopher Swarth, George Didden, Jane Huff

Biogeography and Ecological Opportunity Collection

Urban and suburban habitats often contain a variety of Neotropical migratory birds, but are poorly sampled by programs such as the North American Breeding Bird Survey. DC Birdscape was developed to inventory and monitor birds in Washington, DC. Birds were surveyed using a systematic sample of point counts during 1993-1995. Results indicate that species richness of Neotropical migratory birds varied among land-use categories, and that maximum species richness occurred in parkland habitats. Although DC Birdscape has provided relevant information on bird distribution and species richness, it is unclear whether the information is of sufficient management interest to support its continuation …

Evaluation Of Animal Model Research, Kenneth J. Shapiro

Experimentation Collection

It is argued that a concept of evaluation of animal models that is broader and more useful than validation is available. Productive generativity refers to the degree to which a model furthers understanding and leads to more-effective treatment interventions. Results of the application of this novel evaluative frame to several animal models of eating disorders show that this animal-based research has not been productive. The question of the relation between clinic and animal laboratory is discussed.

Optimization Techniques For Data Intensive Decision Flows, Richard Hull, Francois Llirbat, Bharat Kumar, Gang Zhou, Guozhu Dong, Jianwen Su

Kno.e.sis Publications

For an enterprise to take advantage of the opportunities afforded by electronic commerce it must be able to make decisions about business transactions in near-real-time. In the coming era of segment-of-one marketing, these decisions will be quite intricate, so that customer treatments can be highly personalized, reflecting customer preferences, the customer's history with the enterprise, and targeted business objectives. This paper describes a paradigm called “decision flows” for specifying a form of incremental decision-making that can combine diverse business factors in near-real-time.

This paper introduces and empirically analyzes a variety of optimization strategies for decision flows that are “data-intensive”, i.e. …

Imprecise Answers In Distributed Environments: Estimation Of Information Loss For Multi-Ontology Based Query Processing, Eduardo Mena, Vipul Kashyap, Arantza Illarramendi, Amit P. Sheth

Kno.e.sis Publications

The World Wide Web is fast becoming a ubiquitous computing environment. Prevalent keyword-based search techniques are scalable, but are incapable of accessing information based on concepts. We investigate the use of concepts from multiple, real-world pre-existing, domain ontologies to describe the underlying data content and support information access at a higher level of abstraction. It is not practical to have a single domain ontology to describe the vast amounts of data on the Web. In fact, we expect multiple ontologies to be used as different world views and present an approach to "browse" ontologies as a paradigm for information access. …

Age Differences In Behavior And Pet Activation Reveal Differences In Interference Resolution In Verbal Working Memory, Alan Hartley, John Jonides, Christina Marshuetz, Edward E. Smith, Patricia A. Reuter-Lorenz, Robert A. Koeppe

Scripps Faculty Publications and Research

Older adults were tested on a verbal working memory task that used the item-recognition paradigm. On some trials of this task, response-conflict was created by presenting test-items that were familiar but were not members of a current set of items stored in memory. These items required a negative response, but their familiarity biased subjects toward a positive response. Younger subjects show an interference effect on such trials, and this interference is accompanied by activation of a region of left lateral prefrontal cortex. However, there has been no evidence that the activation in this region is causally related to the interference …

Age Differences In The Frontal Lateralization Of Verbal And Spatial Working Memory Revealed By Pet, Alan Hartley, Patricia A. Reuter-Lorenz, John Jonides, Edward E. Smith, Andrea Miller, Christina Marshuetz, Robert A. Koeppe

Scripps Faculty Publications and Research

Age-related decline in working memory figures prominently in theories of cognitive aging. However, the effects of aging on the neural substrate of working memory are largely unknown. Positron emission tomography (PET) was used to investigate verbal and spatial short-term storage (3 sec) in older and younger adults. Previous investigations with younger subjects performing these same tasks have revealed asymmetries in the lateral organization of verbal and spatial working memory. Using volume of interest (VOI) analyses that specifically compared activation at sites identified with working memory to their homologous twin in the opposite hemisphere, we show pronounced age differences in this …

Ventilatory Accommodation Of Oxygen Demand And Respiratory Water Loss In Kangaroos From Mesic And Arid Environments, The Eastern Grey Kangaroo (Macropus Giganteus) And The Red Kangaroo (Macropus Rufus), Terence J. Dawson, Adam J. Munn, Cyntina E. Blaney, Andrew Krockenberger, Shane K. Maloney

Faculty of Science - Papers (Archive)

We studied ventilation in kangaroos from mesic and arid environments, the eastern grey kangaroo (Macropus giganteus) and the red kangaroo (Macropus rufus), respectively, within the range of ambient temperatures (T-a) from -5 degrees to 45 degrees C. At thermoneutral temperatures (T-a = 25 degrees C), there were no differences between the species in respiratory frequency, tidal volume, total ventilation, or oxygen extraction. The ventilatory patterns of the kangaroos were markedly different from those predicted from the allometric equation derived for placentals. The kangaroos had low respiratory frequencies and higher tidal volumes, even when adjustment was made for their lower basal …

Clusterin Is A Secreted Mammalian Chaperone, M. R. Wilson, S. B. Easterbrook-Smith

Faculty of Science - Papers (Archive)

[Extract] By any criteria, clusterin is an interesting protein. It was first described in 1983 as a secreted glycoprotein in ram rete testis fluid that enhanced aggregation (“clustering”) of a variety of cells in vitro 1. Many homologues in other species were subsequently discovered. Typically, each “discovery” of clusterin in a different species or by a different research group led to it being assigned another name. By the early 1990s clusterin was known under many aliases 2, some of which persist in the literature. However, the inaugural international workshop on clusterin (Cambridge, 1992) agreed to the name clusterin, in deference …

Theories of scarpland geomorphology developed over the past century have been characterised by divergent conceptual frameworks and have been hindered by language barriers. Here, we review the main theories and assess them with reference to field evidence from central Queensland, Australia.

Thyroid Hormones And Their Effects: A New Perspective, A. J. Hulbert

Faculty of Science - Papers (Archive)

The thyroid hormones are very hydrophobic and those that exhibit biological activity are 3',5',3,5-ltetraiodothyronine (T4), 3',5,3-l-triiodothyronine (T3), 3',5',3-l-triiodothyronine (rT3) and 3,5,-ldiiodothyronine (3,5-T2). At physiological pH, dissociation of the phenolic -OH group of these iodothyronines is an important determinant of their physical chemistry that impacts on their biological effects. When non-ionized these iodothyronines are strongly amphipathic. It is proposed that iodothyronines are normal constituents of biological membranes in vertebrates. In plasma of adult vertebrates, unbound T4 and T3 are regulated in the picomolar range whilst protein-bound T4 and T3 are maintained in the nanomolar range. The function of thyroid-hormone-binding plasma proteins …

Desiccation Tolerance Of Three Moss Species From Continental Antarctica, Sharon A. Robinson, J. Wasley, M. Popp, C. E. Lovelock

Faculty of Science - Papers (Archive)

Tolerance of desiccation was examined in three species of moss, Grimmia antarctici Card., Ceratodon purpureus (Hedw.) Brid. and Bryum pseudotriquetrum (Hedw.) Gaertn., Meyer et Scherb. collected from two sites of contrasting water availability in the Windmill Islands, continental Antarctica. Physiological tolerance to desiccation was measured using chlorophyll fluorescence in plugs of moss during natural drying in the laboratory. Differences in relative water contents, rates of drying and the response of photosynthesis to desiccation were observed among the three species and between sites. Of the three species studied, G. antarctici showed the lowest capacity to sustain photosynthetic processes during desiccation, B. …

Tracing Beach Sand Provenance And Transport Using Foraminifera: Preliminary Examples From Northwest Europe And Southeast Australia, S. K. Haslett, Edward A. Bryant, R. H. Curr

Faculty of Science - Papers (Archive)

Foraminifera are marine Sarcodine Protozoa that possess tests (shells) that are preservable in the fossil record. These tests may either be constructed using organically cemented detritus (agglutinating or arenaceous forms), or secreted using calcium carbonate (calcareous forms). Their ecology embraces planktonic and benthonic modes, although planktonic forms generally inhabit the open ocean and seldom live in coastal waters in any abundance, while benthonic foraminifera exist on substrates from abyssal plains to high intertidal areas. There are many species of foraminifera that are niche-specific, making them ideal for palaeoenvironmental analysis (Boersma, 1978; Brasier, 1980; Murray, 1991; Culver, 1993).

Global-Perspective Jitter Improves Vection In Central Vision, Stephen A. Palmisano, Barbara Gillam, Shane Blackburn

Faculty of Health and Behavioural Sciences - Papers (Archive)

Previous vection research has tended to minimise visual - vestibular conflict by using optic-flow patterns which simulate self-motions of constant velocity. Here, experiments are reported on the effect of adding 'global-perspective jitter' to these displays -- simulating forward motion of the observer on a platform oscillating in horizontal and/or vertical dimensions. Unlike non-jittering displays, jittering displays produced a situation of sustained visual - vestibular conflict. Contrary to the prevailing notion that visual - vestibular conflict impairs vection, jittering optic flow was found to produce shorter vection onsets and longer vection durations than non-jittering optic flow for all of jitter magnitudes …

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

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.

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 …

Response To Critique Of The Claim Of Cannibalism At Cowboy Wash, Patricia M. Lambert, Banks L. Leonard, Brian R. Billman, Richard A. Marlar, Margaret E. Newman, Karl J. Reinhard

Karl Reinhard Publications

The original authors of Billman et af. (2000) are joined by three other analysts from the Cowboy Wash research team to respond to the critique of this article by Dongoske et af. (2000). Dongoske and his coauthors state that Billman et af. (2000) failed to test alternative hypotheses or to consider alternative explanations for the findings at 5MTJOOJO and similar sites. The original authors point out that alternative hypotheses were examined and rejected, leaving a violent episode of cannibalism as the most plausible explanation for the remains found at 5MTJOOJO. Dongoske et af. also question many aspects of the osteological, …

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. …

On The Nature Of Norms: Biology, Morality, And The Disruption Of Order, Owen D. Jones

Vanderbilt Law School Faculty Publications

This essay discusses the legal implications of bio-behavioral underpinnings to norms, morality, and economic order. It first discusses the recent book "The Great Disruption: Human Nature and the Reconstitution of Social Order," in which Francis Fukuyama explores the importance of evolved human nature to the reconstruction of social order and a thriving economy. It then addresses the extent to which we can usefully view law-relevant norms as products of evolutionary - as well as economic - processes.

Law And The Biology Of Rape: Reflections On Transitions, Owen D. Jones

Vanderbilt Law School Faculty Publications

This Article serves is a sequel to a previous Article: Sex, Culture, and the Biology of Rape: Toward Explanation and Prevention, 87 Cal. L. Rev. 827 (1999). Part I briefly considers the threshold question: why consider the behavioral biology of sexual aggression at all? Part II proposes that the first step in transitioning to a more accurate and more useful model of rape behavior is to avoid a number of common definitional ambiguities that plague most rape discussions. Because those ambiguities are particularly likely to foster misunderstandings about biobehavioral perspectives, Part II also clarifies the scope of what biobehavioral theories …
