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...

Two-dimensional habitat modeling in the Yellowstone/Upper Missouri River system Two-dimensional habitat modeling in the Yellowstone/Upper Missouri River system

This study is being conducted to provide the aquatic biology component of a decision support system being developed by the U.S. Bureau of Reclamation. In an attempt to capture the habitat needs of Great Plains fish communities we are looking beyond previous habitat modeling methods. Traditional habitat modeling approaches have relied on one-dimensional hydraulic models and lumped...

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...

Book review: Riparian ecosystem recovery in arid lands: Strategies and references Book review: Riparian ecosystem recovery in arid lands: Strategies and references

Increasingly, ecosystem managers are attempting to restore riparian ecosystems in the arid West that have been degraded by land and water management practices. This book will fill a vacant niche in the library of these practitioners. Briggs emphasizes several concepts that should be fundamental to restoration projects but that too often are ignored. One of these central concepts is that...
