Translocations as a tool for restoring populations of bighorn sheep Translocations as a tool for restoring populations of bighorn sheep

We analyzed factors that contributed to the success of 100 translocations of bighorn sheep within six western states between 1923 and 1997. We categorized the populations as unsuccessful (i.e., extirpated or remnant,

Channel incision and patterns of cottonwood stress and mortality along the Mojave River, California Channel incision and patterns of cottonwood stress and mortality along the Mojave River, California

In 1995, mapping and classification of riparian vegetation along the Mojave River in southern California revealed an 8-km reach in which riparian cottonwoods (Populus fremontii Wats.) were stressed or dying. We tested a set of predictions based on the inference that cottonwood decline was an indirect result of lowered water-table levels following flood-related channel incision...

Potential effects of climate change on surface-water quality in North America Potential effects of climate change on surface-water quality in North America

Data from long-term ecosystem monitoring and research stations in North America and results of simulations made with interpretive models indicate that changes in climate (precipitation and temperature) can have a significant effect on the quality of surface waters. Changes in water quality during storms, snowmelt, and periods of elevated air temperature or drought can cause conditions...

Application of the new keystone-species concept to prairie dogs: How well does it work? Application of the new keystone-species concept to prairie dogs: How well does it work?

It has been suggested that the keystone-species concept should be dropped from ecology and conservation, primarily because the concept is poorly defined. This prompted Power et al. (1996) to refine the definition: keystone species have large effects on community structure or ecosystem function (i.e., high overall importance), and this effect should be large relative to abundance (i.e...

The bats of Wyoming The bats of Wyoming

We examined 1280 bats of 12 species submitted to the Wyoming State Veterinary Laboratory (WSVL) for rabies testing between 1981 and 1992. The most abundant species in the sample was Myotis lucifugus, followed by Eptesicus fuscus, Lasionycteris noetivagans, M. ciliolabrum, and M. volans. Using the WSVL sample and additional museum specimens, we summarized available records and knowledge...

Multicriteria decision analysis applied to Glen Canyon Dam Multicriteria decision analysis applied to Glen Canyon Dam

Conflicts in water resources exist because river-reservoir systems are managed to optimize traditional benefits (e.g., hydropower and flood control), which are historically quantified in economic terms, whereas natural and environmental resources, including in-stream and riparian resources, are more difficult or impossible to quantify in economic terms. Multicriteria decision analysis...

Management of land use conflicts in the United States Rocky Mountains Management of land use conflicts in the United States Rocky Mountains

People have long been attracted to the beauty and grandeur of the Rocky Mountains. Until very recently, however, the Rocky Mountain region was sparsely populated and its use mostly extractive. Commodities removed in massive quantities included first beaver, then precious metals, timber, energy, and finally water. There has been a fundamental change in migration patterns since the 1980s
