Viewpoint: Sustainability of piñon-juniper ecosystems - A unifying perspective of soil erosion thresholds Viewpoint: Sustainability of piñon-juniper ecosystems - A unifying perspective of soil erosion thresholds

Many pinon-juniper ecosystem in the western U.S. are subject to accelerated erosion while others are undergoing little or no erosion. Controversy has developed over whether invading or encroaching pinon and juniper species are inherently harmful to rangeland ecosystems. We developed a conceptual model of soil erosion in pinon-jumper ecosystems that is consistent with both sides of the...

Evaluating landscape health: Integrating societal goals and biophysical process Evaluating landscape health: Integrating societal goals and biophysical process

Evaluating landscape change requires the integration of the social and natural sciences. The social sciences contribute to articulating societal values that govern landscape change, while the natural sciences contribute to understanding the biophysical processes that are influenced by human activity and result in ecological change. Building upon Aldo Leopold's criteria for landscape...

Survey and assessment of amphibian populations in Rocky Mountain National Park Survey and assessment of amphibian populations in Rocky Mountain National Park

We conducted surveys in Rocky Mountain National Park, Colorado for amphibians in 1987-1994. Four species, Ambystoma tigrinum, Bufo boreas, Pseudacris maculata, and Rana sylvatica, were recorded. Pseudacris maculata was the most widely distributed and abundant species in the Park. Two populations of E maculata were estimated to contain 161 and 136 breeding males in 1988. There was no...

Flood dependency of cottonwood establishment along the Missouri River, Montana, USA Flood dependency of cottonwood establishment along the Missouri River, Montana, USA

Flow variability plays a central role in structuring the physical environment of riverine ecosystems. However, natural variability in flows along many rivers has been modified by water management activities. We quantified the relationship between flow and establishment of the dominant tree (plains cottonwood, Populus deltoides subsp. monilifera) along one of the least hydrologically...

Comparison of tree basal area and canopy cover in habitat models: Subalpine forest Comparison of tree basal area and canopy cover in habitat models: Subalpine forest

Canopy cover and basal area are 2 common measures of tree cover used in forest wildlife habitat models and resource selection studies. When choosing between these 2 measures, it is important to recognize that they may differentially estimate relative cover of coexisting tree species due to differences in bole diameter distributions, crown overlap, and crown widths as a function of bole...

A comparison of sevoflurane and isoflurane for short-term anesthesia in polecats (Mustela eversmanni) A comparison of sevoflurane and isoflurane for short-term anesthesia in polecats (Mustela eversmanni)

Twenty-four Siberian polecats (Mustela eversmanni) from 12 litters were anesthetized with either inhaled sevoflurane or isoflurane. With 7% delivered sevoflurane and 5% delivered isoflurane, time to loss of righting reflex (mean +/- SE) with sevoflurane (1.9 +/- 0.1 min) was significantly shorter compared with isoflurane (2.6 +/- 0.1 min). During maintenance at a light plane of...
