The activity rhthms and home ranges of alpine weasels were studied by telemetric techniques in 1990 at YUER mountain near Haibei Research Station of Alpine Meadow Ecosystem.The main activities of alpine weasels were as follows: play, self-groom, sunbath, explore, fecd, and activities of alpine weasels were as follows: play, self-groom, sunbath, explore,dens, the daily activity peads of adult femal

We explored the difference between the concentrations of different N forms and other chemical properties between stream water and riparian zone wetland soil water in the Loch Vale Watershed which is located on the eastern slope of the Continental Divide in Rocky Mountain National Park, Colorado, USA. The nitrate N concentration in stream water were significantly higher than in soil water of the th

The composition of milk from early pouch life (0-40 days) to weaning (360 days) was determined in samples collected from a field population of red kangaroos, Macropus rufus (n = 150). Total milk solids increased from 11% at 0-40 days to 26% at permanent emergence from the pouch (235 days), then decreased towards weaning. Compared with other macropodids, milk from red kangaroos is relatively dilute

The effects of river regulation on bottomland tree communities in western North America have generated substantial concern because of the important habitat and aesthetic values of these communities. Consideration of such effects in water management decisions has been hampered by the apparent variability of responses of bottomland tree communities to flow alteration. When the relation between strea

We reconstructed fire history in ponderosa pine and mixed-conifer forests across the Jemez Mountains in northern New Mexico. We collected fire-scarred samples from ten ponderosa pine areas, and three mesic mixed-conifer areas. Prior to 1900, ponderosa pine forests were characterized by high frequency, low intensity surface fire regimes. The mixed-conifer stands sustained somewhat less frequent sur

Scientists at the Mid-Continent Ecological Science Center of the National Biological Service conducted a series of case studies of Federal Energy Regulatory Commission license consultations. The goal of these studies was to test hypotheses about factors that contribute to success in interagency negotiations. Based on their analysis of six case studies, the researchers constructed a list of ten "ru
