Similarity in habitat adaptations of Arctic and African ungulates: evolutionary convergence or ecological divergence?
March 22, 2001... ABSTRACT: Caribou (Rangifer tarandus) and muskoxen (Ovibos moschatus) partition habitat use in the Arctic differently in relation to their morphological, physiological, and behavioral attributes. Adaptations to Arctic habitats by caribou result...

Density dependence of ungulates and functional responses of wolves: effects on predator-prey ratios.(Statistical Data Included)
March 22, 2001... ABSTRACT: Predator-prey ratios have been used widely to interpret effects of wolf (Canis lupus) predation on their ungulate prey. Use of those simple indices may be misleading unless they are interpreted with regard to species composition of...

Seasonality of sexual segregation in dimorphic deer: extending the gastrocentric model.(Statistical Data Included)
March 22, 2001... ABSTRACT: We extend our gastrocentric model for sexual segregation in dimorphic deer (Cervidae) to include seasonal metabolism of energy and protein in reproductive female, nonreproductive female, and male reindeer and caribou (Rangifer...

Mercury in hair of large Alaskan herbivores: routes of exposure.(Statistical Data Included)
March 22, 2001... ABSTRACT: Atmospheric-soil cycling of mercury is a process ultimately affecting mercury distribution to upper trophic levels in terrestrial ecosystems. In the Arctic and sub-Arctic, there is a paucity of information on processes and pathways...

Vigilance behavior in wild and semi-domestic reindeer in Norway.(Statistical Data Included)
March 22, 2001... ABSTRACT: We recorded vigilance behavior of a wild reindeer (Rangifer tarandus tarandus) population in Rondane North and a population of semi-domesticated origin in Norefjell-Reinsjofjell during 3 periods (April-May, June-July, and August) in...

Visibility bias and development of a sightability model for tule elk.(Statistical Data Included)
March 22, 2001... ABSTRACT: Tule elk (Cervus elaphus nannodes) are endemic to California, USA, and occupy habitats that differ greatly from those inhabited by many other elk populations. Because of the importance of demographic data to the conservation of this...

Stable isotope signatures of moose in relation to seasonal forage composition: a hypothesis.(Statistical Data Included)
March 22, 2001... ABSTRACT: Forage plants consumed by moose (Alces alces) during winter are isotopically divergent from the forage plants potentially eaten during summer. I examined the natural abundance of [sup.15]N and [sup.13]C in moose from north-central...

Habitat use by black-tailed deer in relation to rate of forage intake.(Statistical Data Included)
March 22, 2001... ABSTRACT: Availability of digestible energy is potentially the most important limiting factor for black-tailed deer (Odocoileus hemionus sitkensis) from a nutritional perspective, but patch use by other ruminants has been better correlated with...

Dispersal and migration in northern forest deer--are there unifying concepts?
March 22, 2001... ABSTRACT: I summarize studies of natal dispersal and seasonal migrations in 5 species of forest deer: moose (Alces alces), roe deer (Capreolus capreolus), white-tailed deer (Odocoileus virginianus), mule deer (O. hemionus), and black-tailed...

Causes and consequences of sociality in mule deer.
March 22, 2001... ABSTRACT: We tested hypotheses concerning evolution of sociality in mule deer (Odocoileus hemionus) by examining effects of resources and risk of predation on group size of these large herbivores. Groups of deer were largest during rut and...

Reproductive patterns of female muskoxen in northeastern Alaska.(Statistical Data Included)
March 22, 2001... ABSTRACT: Reproductive success is an important variable in the dynamics of a re-established population of muskoxen (Ovibos moschatus) in the Arctic National Wildlife Refuge, Alaska, USA. From observations of marked female muskoxen between 1982...

Sex-specific dynamics of north american elk in relation to global climate.(Statistical Data Included)
March 22, 2001... ABSTRACT: The North Atlantic Oscillation (NAO) is a continuous fluctuation in atmospheric mass balance that drives most interannual and decadal variation in winter temperatures and precipitation in the Northern Hemisphere. Effects of the NAO on...

Utility of stable isotope analysis in studying foraging ecology of herbivores: examples from moose and caribou.(Statistical Data Included)
March 22, 2001... ABSTRACT: Recently, researchers emphasized that patterns of stable isotope ratios observed at the individual level are a result of an interaction between ecological, physiological, and biochemical processes. Isotopic models for herbivores...

Fright and flight behavior of reindeer.(Statistical Data Included)
March 22, 2001... ABSTRACT: Vigilance and avoidance behaviors of 8 reindeer (Rangifer tarandus) populations from different geographical areas were examined by measuring distances of detection and flight from a human approaching on foot. Differences in behavior...

Tree rubbing by white rhinos: potential functions of an undescribed behavior.(Statistical Data Included)
March 22, 2001... ABSTRACT: I observed white rhinos (Ceratotherium simum) in Matobo National Park, Zimbabwe, perform a behavior previously undescribed for this species; males vigorously removed the bark from commiphora trees (Commiphora marlothii) with their...

Stumbling towards enlightenment: understanding caribou dynamics.
March 22, 2001... ABSTRACT: I review what biologists now think we know about caribou dynamics (Rangifer tarandus) and how we came by this knowledge, in the hope that there are some lessons that will help us learn more efficiently in the future. Prior to the late...

Effects of marcescent leaves on winter browsing by large herbivores in northern temperate deciduous forests.(Statistical Data Included)
March 22, 2001... ABSTRACT: Presence of marcescent leaves during winter is a common phenomenon in northern-temperate deciduous forests across the Holarctic, but the ecological significance of marcescence on woody vegetation has received little attention....

Effects of horn-curl regulations on demography of Dall's sheep: a critical review.(Statistical Data Included)
March 22, 2001... ABSTRACT: Researchers studying Dall's sheep (Ovis dalli dalli) associated with a large mineral lick on Dry Creek in the central Alaska Range south of Fairbanks, Alaska, USA, claimed that removal of nearly all mature males by intensive harvest...

Regional variation in mineral contents of plants and its significance for migration by arctic reindeer and caribou.(Statistical Data Included)
March 22, 2001... ABSTRACT: Ten minerals, 6 macro (Na, K, Ca, P, Mg, Cl) and 4 trace clements (Co, Cu, Mo, Mn), were analysed in 13 forage plants of reindeer and caribou (Rangifer tarandus) to compare differences between coastal and interior areas. Samples were...
