Effects of ethyl mercury on some parameters of reproduction in ring-necked pheasants

Creator:: Christensen, Alan Gene
Abstract:: Prior to onset of the breeding season, a ration containing 18.4 mg/kg N-(Ethylmercuri)-p-toluene sulphonanilide was fed to 6 male and 16 female ring-necked pheasants (Phasianus colchicus). Birds receiving the mercury-treated ration were separated from the opposite sex. After receiving the mercury-treated ration for 0, 2, 4, 8, or 16 days,...

Insect mycophagy : a preliminary bibliography

Creator:: Fogel, Robert, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: This bibliography of insect mycophagy results from a literature search on the ecology of hypogeous fungi. It is hoped that this admittedly incomplete list will provide a nucleus of references for those unfamiliar with the topic. Using the "bracket" fungi (Polyporaceae) as an example, most of the literature can be...

A review of forest biomass accumulation

Creator:: Turner, John, Cole, Dale W., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: "This report presents a reference list of available studies on aboveground forest biomass, together with (1) methods of sampling and estimation and some of the problems and errors associated with each method (given as an aid to comparison of data), (2) some results obtained from the literature of field estimates...

Terrestrial decomposition 1973 : a synopsis

Creator:: Fogel, Robert, Cromack, Kermit, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: This report describes decomposition studies conducted in the H. J. Andrews Forest, Oregon in 1973. Changes in weight loss and nutrient content of leaves, cones, branches, and bark of Douglas-fir and leaves of big-leaf maple, vine maple, Rhododendron, red alder, sword fern Oregon oak, and Chinkapin were recorded in a...

Microbial ecology of an old-growth Douglas fir canopy

Creator:: Caldwell, Bruce A.
Abstract:: Microbial populations associated with the major substrates of the canopy of a 70 m old-growth Douglas fir were studied to determine potential activities. Seasonal samples from bark, foliage, epiphytic moss, lichens, and litter accumulations were collected to i) obtain population data, ii) to isolate the major groups of microorganisms present,...

Comparative rates of CO₂ production from the forest floor in the Douglas-fir ecosystem

Creator:: Phillips, Michael John
Abstract:: To obtain data on the decomposition of the forest floor, a battery operated electrolytic respirometer was developed making it possible to measure CO₂ evolution from field moist forest floor samples in situ independent of root respiration. Banks of four respirometers powered by two 12-volt batteries were installed in three old...

The effects of tritiated seawater on development of the goose barnacle Pollicipes polymerus

Creator:: Abbott, David Thomas
Abstract:: The purpose of this study was to determine the effects of tritiated seawater (HTO) on selected developmental stages of the goose barnacle, Pollicipes polymerus. Barnacle embryos were cultured in Millipore cytology monitors with HTO concentrations of 0, 10⁻⁵, 10⁻³, 10⁻¹, and 10¹ μCi/ml. After 22 days, hatching was complete and...

Mercury accumulation in fish from Cottage Grove Reservoir and its tributaries

Creator:: Worcester, Thomas C
Abstract:: A fish sampling program was initiated at Cottage Grove Reservoir in June of 1974 to investigate mercury accumulation in the fish. Samples were collected periodicallv from June to November, 1974, and from June, 1975 through January, 1976 from both the reservoir and its tributaries. Species collected included spring chinook salmon...
