Cyst acquisition rate for Giardia lamblia in backcountry travelers to Desolation Wilderness, Lake Tahoe
S.C. Zell, S. K. Sorenson
1993, Journal of Wilderness Medicine (4) 147-154
The objective of this study was to determine the incidence of Giardia lamblia acquisition in back-country travelers to a wilderness area, provide longitudinal follow-up on the incidence of symptomatic gastrointestinal illness and relate such information to concentrations of Giardia cysts in water samples from a high-use area. A prospective cohort...
Population trend of the Yellowstone grizzly bear as estimated from reproductive and survival rates
L. L. Eberhardt, B. M. Blanchard, R. R. Knight
1993, Canadian Journal of Zoology (72) 360-363
The trend of the Yellowstone grizzly bear (Ursus arctos horribilis) population was estimated using reproductive rates calculated from 22 individual females and survival rates from 400 female bear-years. The point estimate of the rate of increase was 4.6%, with 95% confidence limits of 0 and 9%. Caution in interpreting this...

Sensitivity of water resources in the Delaware River basin to climate variability and change
Mark A. Ayers, David M. Wolock, Gregory J. McCabe, Lauren E. Hay, Gary D. Tasker
1993, Open-File Report 92-52
Because of the "greenhouse effect," projected increases in atmospheric carbon dioxide levels might cause global warming, which in turn could result in changes in precipitation patterns and evapotranspiration and in increases in sea level. This report describes the greenhouse effect; discusses the problems and uncertainties associated with the detection, prediction,...
Bathymetry of southern Mauna Loa Volcano, Hawaii
William W. Chadwick, James G. Moore, Michael O. Garcia, Christopher G. Fox
1993, Miscellaneous Field Studies Map 2233
Manua Loa, the largest volcano on Earth, lies largely beneath the sea, and until recently only generalized bathymetry of this giant volcano was available. However, within the last two decades, the development of multibeam sonar and the improvement of satellite systems (Global Positioning System) have increased the availability of precise...
