Evaluating temperature regimes for protection of brown trout
Carl L. Armour
1994, Report
Geographic distribution and population success of brown trout (Salmo trutta) are affected by temperature regimes. Concepts are presented for evaluating alternative temperature regimes for brown trout based on published temperature information and professional judgment. Temperature information from the literature is included for spawning runs, spawning, egg and larval development, growth,...
Physiological responses of Yellowstone bison to winter nutritional deprivation
Glenn D. DelGiudice, Francis J. Singer, Ulysses S. Seal, Gillian Bowser
1994, Journal of Wildlife Management (58) 24-34
Because nutrition is critically related to other aspects of bison (Bison bison) ecology, and the winter ranges inhabited by bison in Yellowstone National Park (YNP) are ecologically diverse, it was important to determine if nutritional deprivation differences occurred among winter ranges. We used chemistry profiles of urine suspended in snow...

Tertiary structural evolution of the southern Rhodope metamorphic province: a fundamental revision
D. Dinter
1994, Conference Paper, Proceedings of the 7th congress of the Geological Society of Greece with emphasis on the geology of Macedonia and Thrace
The Rhodope province is conventionally interpreted as a continental fragment that was caught between Apulia and Europe and deformed and metamorphosed in the hinterland of the Hellenic collisional orogen. Geologic mapping in the Strymon Valley region of northeastern Greece augmented by new U-Pb and 40Ar/ 39Ar geochronologic data support an...
Evaluation of tire reefs for enhancing aquatic communities in concrete-lined canals
Gordon Mueller, Charles R. Liston
1994, North American Journal of Fisheries Management (14) 616-625
Large earthen canals in the arid southwest are being lined with concrete to reduce seepage and conserve limited water supplies. Lining reduces habitat and increases operational velocities (relative to unaltered streams), which are detrimental to aquatic communities. Fish communities that become reestablished in these waterways exhibit lower species...
Evaluation of Canada goose sterilization for population control
Kathryn A. Converse, James J. Kennelly
1994, Wildlife Society Bulletin (22) 265-269
We evaluated the vasectomy of 72 male Canada geese as a method to control growing populations of nuisance geese in Westchester County, New York. Thirty-three of the vasectomized males paired with a female and were located during ≥1 breeding seasons; 7 treated males were not seen following surgery. The remaining...

Analysis of nitrogen saturation potential in Rocky Mountain tundra and forest: implications for aquatic systems
Jill S. Baron, Dennis S. Ojima, Elisabeth A. Holland, William J. Parton
1994, Biogeochemistry (27) 61-82
We employed grass and forest versions of the CENTURY model under a range of N deposition values (0.02–1.60 g N m−2 y−1) to explore the possibility that high observed lake and stream N was due to terrestrial N saturation of alpine tundra and subalpine forest in Loch Vale Watershed, Rocky...
Chemical, isotopic, and dissolved gas compositions of the hot springs of the Owyhee Uplands, Malheur County, Oregon

Hot springs along the Owyhee River in southeastern Oregon between Three Forks and Lake Owyhee could be part of a north flowing regional system or a series of small separate geothermal systems Heat for the waters could be from a very young (Holocene) volcanic activity (basalt flows) of the Owyhee...
