Survival Of Trout Strains As Affected By Limnological Parameters, Wayne A. Wurtsbaugh Dec 1988

Survival Of Trout Strains As Affected By Limnological Parameters, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Prior work at East Canyon Reservoir, Utah indicated that adult trout are important predators of stocked juvenile rainbow trout. Brown trout, in particular, were exclusively piscivorous when th~y exceeded 185 mm standard length. Fish became increasingly important in the diet of cutthroat trout greater than 330 mm. The purpose of this study was to further document the effect of adult trout on survival of juvenile rainbow trout in mid-elevation reservoirs. Causey Reservoir was chosen because it was thought to contain large brown and cutthroat trout and had not been intensively studied during the last eight years.

National List Of Plant Species That Occur In Wetlands: Intermountain (Region 8), Porter B. Reed, Jr., National Ecology Research Center May 1988

National List Of Plant Species That Occur In Wetlands: Intermountain (Region 8), Porter B. Reed, Jr., National Ecology Research Center

All U.S. Government Documents (Utah Regional Depository)

The National List of Plant Species That Occur in Wetlands represents the combined efforts of many biologists over the last decade to define the wetland flora of the United States. The U.S. Fish and Wildlife Service initially developed the list in order to provide an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (FWS/OBS 79/31) to assist in the field identification of wetlands. Plant species that occur in wetlands, as used in the National List are defined as species that have demonstrated an ability to achieve maturity and reproduce in an environment where all or …

A Model Of Energy Expenditure In White-Tailed Jackrabbits (Lepus Townsendii) Based On Integrated Studies Of Energetics And Field Ecology, Gordon L. Rogowitz May 1988

A Model Of Energy Expenditure In White-Tailed Jackrabbits (Lepus Townsendii) Based On Integrated Studies Of Energetics And Field Ecology, Gordon L. Rogowitz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Field and laboratory studies were conducted to develop a model of energy expenditure in a population of white-tailed jackrabbits (Lepus townsendii). Field work in southwestern Wyoming during 1985-87 showed that the breeding season commenced at snowmelt and ceased during late- July drought. Adult females reproduced relatively synchronously and produced a mean of three litters annually. Greatest fetal production occurred in the second litter period. Collections indicated a 1:1 sex ratio, few jackrabbits >2 years-old, and a density of 7 animals / km2 in the population. Postnatal growth was sigmoidal, culminating in heavier adult females than males. Using …

Fossil Butte Environmental Assessment, Develop Visitor, Administrative, And Maintenance Facilities, United States, Department Of The Interior, National Park Service

Environmental Assessments (WY)

The National Park Service (NPS) proposes to construct the first permanent visitor, administrative, and maintenance facilities at Fossil Butte National Monument since its Congressional establishment in 1972. Proposed facilities include: a 4,800-square-foot visitor center and administrative building on a 2-acre site approximately 1 mile north of Lincoln County Road 300; and a 2,000-square-foot maintenance building, materials storage yard, and seasonal-employee housing unit on a 5-acre site near the southwest corner of the monument. The employee housing unit is not part of this package and would be constructed at a later date if additional funding becomes available. Other proposed development includes …

Environmental Assessments (WY)

Reconstruction is proposed for 12 miles of the Teton Park Road between Moose Junction and North Jenny Lake Junction, as well as 6.5 miles of the Jenny Lake one-way loop road and the 0.5 mile long String Lake road. The project is being planned and designed in two segments. Segment A extends between Moose Junction and a point near the Climbers Ranch road intersection (4 miles north of Moose Junction), and segment B continues from that point to North Jenny Lake junction and includes modification of the String/Jenny Lake road and parking complex. Segment A would be constructed under a …

Historical Vegetation, Fuel Loads, And Integrated Resource Information System For Bryce Canyon National Park, Utah State University, Department Of Forest Resources And Ecology Center Jan 1988

Historical Vegetation, Fuel Loads, And Integrated Resource Information System For Bryce Canyon National Park, Utah State University, Department Of Forest Resources And Ecology Center

Elusive Documents

This report describes a comprehensive approach to understanding the role and effects of fire in Bryce Canyon National Park. The study includes a reconstruction of the historic vegetation of Bryce Canyon National Park from historic photographs, inference from computer simulation models, and research in areas of similar vegetation. The successional pathways from the historic vegetation to the present are discussed and the landscape scale consequences of fire suppression and successional devolopment are addressed.

A Mass Mortality Of Fishes In Lake Titicaca (Peru-Bolivia) Associated With The Protozoan Parasite Ichthyophthirius Multifiliis, Wayne A. Wurtsbaugh, R. Alfaro Jan 1988

A Mass Mortality Of Fishes In Lake Titicaca (Peru-Bolivia) Associated With The Protozoan Parasite Ichthyophthirius Multifiliis, Wayne A. Wurtsbaugh, R. Alfaro

Watershed Sciences Faculty Publications

In December 1981 , an epizootic of the protozoan parasite Ichthyophthirius multifiliis killed an estimated 18 million killifish Orestias spp. in Lake Titicaca, a high-altitude tropical system. Of the dead fish collected, 93% were adult O. agassii, a commercially important species that is abundant in the littoral zone. Juvenile Orestias spp., pelagic species, and some other littoral zone fis hes were slightly affected. lchthyophthirius multifiliis was probably introduced with exotic fishes brought to Lake Titicaca in the 1940s and 1950s.

National List Of Plant Species That Occur In Wetlands: 1988, Nevada, Porter B. Reed, Jr.

All U.S. Government Documents (Utah Regional Depository)

The National List of Plant Species That Occur in Wetlands: 1988 (National List) represents the combined efforts of many biologists over the last decade to define the wetland flora of the United States. The National List has undergone a number of revisions resulting from intensive review by regional ecologists. National, regional and State lists are being distributed to provide users with the most current information. We welcome and encourage modification and improvement of the National List. Refinement of the National List will occur continually, reflecting increased knowledge in Indicator assignments, taxonomy, and geographic distribution. We anticipate that further refinement of …
