Productivity and nesting habitat of Great Basin Canada geese : Umatilla National Wildlife Refuge

Creator:: McCabe, Thomas R.
Abstract:: Great Basin Canada goose (Branta canadensis moffitti) productivity and nesting habitat utilization were studied on the Columbia River within the boundaries of the Umatilla National Wildlife Refuge during the springs of 1974 and 1975. Five islands, BL-1, BL-2, SD-1, SD-2, and Telegraph Island (TI), contained 88 percent of the nesting...

Some lizard-habitat relationships in the Northern Great Basin

Creator:: Rostker, Margaret Anne
Abstract:: Five sympatric species of desert lizards (leopard lizards (Garnbelia wizlizeni), sagebrush lizards (Sceloporus graciosus), side-blotched. lizards (Uta stansburiana), desert horned lizards (Phrynosoma platyrhinos), and Western whiptails (Cnemidophorus tigris)) were studied in June and July of 1978 and 1979 in northern Nevada on the Charles Sheldon National Wildlife Refuge. Lizard distribution,...

Time and energy budgets of a population of dippers (Cinclus mexicanus) during winter in the Cascade Range of Oregon

Creator:: Parsons, David R.
Abstract:: A time and energy budget was constructed for a population of dippers (Cinclus Mexicanus) in the Cascade Range of Oregon during winter. A total of 12,202 point observations of activity were made from nine observation blinds from 19 November 1973 to 10 February 1974. Approximately 50 percent of all observations...

Utilization of dietary protein by the mussel, Mytilus edulis trossulus (Linnaeus 1758)

Creator:: Kreeger, Daniel A.
Abstract:: Protein microcapsules (PM) were developed as a tool for investigating aspects of dietary protein utilization by mussels, Mytilus edulis trossulus. Digestion of PM in vitro by protease, trypsin, amylase and extracts from the gut of mussels varied significantly depending on the type of protein encapsulated or whether carbohydrates were added...

The effects of water velocity, photoperiod and substrate on the survival and growth of sub-yearling Oregon crayfish (Pacifastacus trowbridgii) Stimpson

Creator:: Hutton, Mark Irvin
Abstract:: In an effort to enhance the possibilities of commercially rearing crayfish (Pacifastacus trowbridgii), the subyearling segment of the life cycle was examined to determine practical ways of increasing survival and growth. Four experiments were designed to study the effects of water velocity, photoperiod, substrate and density of stocking on the...

The horizontal distribution and vertical migrations of the limnetic zooplankton in Crater Lake, Oregon

Creator:: Hoffman, F. Owen
Abstract:: During the summers of 1967 and 1968 the horizontal distribution and did vertical migrations of zooplankton were studied within the unique environment of Crater Lake. Sampling of the horizontal distribution was done by towing plankton nets vertically in different locations. The vertical distribution was sampled by towing at different depths...

Ration and toxicant preexposure influence dieldrin accumulation by rainbow trout

Creator:: Shubat, Pam
Abstract:: Whole body accumulation and tissue distribution of dieldrin (HEOD1) in rainbow trout was studied through oral dose disposition tests and subchronic exposures via water (0.04 and 0.08 jig dieldrin/l) and/or diet (0.087 jig dieldrin/g fish/day). Growth and maintenance rations of 4 and 2% body weight/day were employed. Subchronic testing produced...
