Percentages positive for and numbers of D. viviparus larvae in elk feces was monitored during the fall hunting season of 1975. Fifteen percent (5 to 33) of the elk checked were positive for D. viviparus according to lung dissections conducted during the period of November 15-18, 1975, in Teton Park.</p>1976-01-01T00:00:00-07:00Copyright (c) 1976 Robert C.

Although a knowledge of the social system is a prerequisite to understanding various reproductive and endocrinologic phenomena seen by other workers studying Microtus, Mus, and Peromyscus in the labrotory, behavior and sociality of Microtus in the field have been overlooked because they are difficult to study and because emphasis in microtine research has been placed on the microtine population "cycle".

Only one month (May 22 to June 22) was spent in the park during 1976, and thus no data on swan productivity were obtained in that year. Data on the park's swan production for the years prior to 1974 were obtained from the card files of the National Park Service and have been organized in such a way as to make them comparable to similar data by J. Halladay from Yellowstone National Park (Proceedings of the Third Trumpeter Swan Society Conference, 1973), and published data from Red Rock Lakes National Wildlife Refuge (North American Fauna No. 63, 1960) and from Alaska (Wildlife Monographs (No. 26, 1971), and R. Page's unpublished data from Red Rock Lakes (Ph. D. dissertation, University of Montana, 1974).</p>1976-01-01T00:00:00-07:00Copyright (c) 1976 Paul A.

The results presented here are the product of only one summer's data, and will be subject to rigorus testing in the next two summers. This project has been supported in part by a New York Zoological Society Scholarship and a National Science Foundation Energy-Related Traineeship. I wish to thank Pete Hayden of Grand Teton National Park, Max Rollefson, Jon Erickson, and John Kiefling, of the Wyoming Game and Fish Commission, and John Varley and Ron Jones of the U.S. Fish and Wildlife Service for their cooperation in collection of cutthroat trout. I would also like to thank Drs. R .M. Kitchin, H. Bergman, and G. T. Baxter, of the Department of Zoology and Physiology, University of Wyoming for their help in organizaing this research project.</p>1976-01-01T00:00:00-07:00Copyright (c) 1976 Eric J.

When deep crusted snow prevents the elk from grazing normally, a supplemental feeding program is put into operation. In order for Teton County to meet the 1983 National Goal on water quality (PL 92-500) it is important to determine to what extent the winter feeding of elk is influencing the water quality of Flat Creek which flows through the National Elk Refuge.</p>1976-01-01T00:00:00-07:00Copyright (c) 1976 Gordon A.

Stuarthttps://journals.uwyo.edu/index.php/jhrs/article/view/4913Some Effects of Fire Suppression and Prescribed Burning on Birds and Small Mammals in Sagebrush2019-11-28T10:03:51-07:00John McGeescholcom@uwyo.edu<p>Ecosystems in northwestern Wyoming have remained relatively unpertrubed by fire for the last 70-80 years. Recently a fire management plan was implemented in the Teton wilderness allowing natural fires to burn, and similar plans are being developed for other wilderness areas in Wyoming and central Idaho. Large portions of these areas consist of sagebrush (Artemisia tridentata) communities where natural fires frequently occur. Prescribed burning in sagebrush is also an expanding program in this region. Burning is often used to reduce sagebrush densities, increase forage production for livestock and improve certain wildlife habitat. Plans to use prescribed fire to simulate the ecological effects of a natural fire regime in Jackson Hole are also being developed. These plans are based on the contention that fires are necessary to maintain diversity within many ecosystems of the Jackson Hole region, and the exclusion of fire has resulted in increased areas occupied by sagebrush communities. Studies of the effects of fire in sagebrush on consumers, including both invertebrates and vertebrates, are virtually non-existent. Even for some of the more conspicuous groups like birds, the best available information on response to shrub habitat alteration comes from studies on the effects of herbicides. This study was designed to explore the response of bird and small mammal density and diversity to fire. Field operations were based from the JHBRS at Moran, Wyoming.</p>1976-01-01T00:00:00-07:00Copyright (c) 1976 John M.

However, factors that govern various phases of the cycle are poorly understood. In other words, little is known to what degree environmental factors and physiological responses of the animals contribute to such cyclicity. The purpose of the present study was essentially fourfold: A. Characterization of environmental variables that might affect Microtus populations at three or four different times of the year. B. Investigation of growth, maturation, and reproductive activity of Microtus montanus under natural conditions. C. Study of maturation molts and seasonal pelage changes in Microtus montanus in relation to sex, age, and reproductive status. D. A correlation of the information obtained in #1-3 above. It is hoped that the results will help to elucidate causes underlying the multiannual fluctuations in population density of microtine rodents.</p>1976-01-01T00:00:00-07:00Copyright (c) 1976 Aelita J.

In the past decade private floating within the Park boundaries has increased six-fold, and this use is expected to continue to increase in the future. This study is investigating the recreational social carry capacity, the amount and kind of use an area can support over time without causing an unacceptable change in the experience, of the Snake River by investigating the two user groups, the commercial floater and the private floater.</p>1976-01-01T00:00:00-07:00Copyright (c) 1976 Donald S.
