1980, Avian Diseases (24) 1044-1049
A coccidiosis epizootic has occurred in lesser scaup (Aythya affinis) at Bluestem Reservoir in eastern Nebraska during the spring in each of three recent years: 1976-1978. Losses peaked during the period from mid-March through April. As much as 29% of the peak population of scaup using the reservoir died. Necropsies...
Flood risks and the willingness to purchase flood insurance
M.R. Karlinger, E. D. Attanasi
1980, Water Resources Research (16) 617-622
Computer simulation experiments were conducted to determine the effects of alternative sources of uncertainty on the willingness to pay for flood insurance. Two alternative insurance protection schemes were investigated: coinsurance and fixed coverage. The question investigated here is to what extent does the insurance scheme influence how purchasers respond to...
Quantile estimation with more or less floodlike distributions
J. Maciunas Landwehr, N.C. Matalas, J.R. Wallis
1980, Water Resources Research (16) 547-555
The desirable properties of an estimator relative to a hypothetical population may be irrelevant in practice unless the population at issue more or less resembles the hypothetical population. Evidence that floods are distributed with long, stretched upper tails suggests that use of the more common distributions results in a rather...

Everett Louis King Jr.
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 1989-2006
Criteria for the classification of marks inflicted by sea lamprey (Petromyzon marinus) into nine categories were developed from laboratory studies in an attempt to refine the classification system used in field assessment work. These criteria were based on characteristics of the attachment site that could be identified under field conditions...
The behavior of 14C and 13C in estuarine water: Effects of In situ CO2 production and atmospheric exchange
Elliott C. Spiker
1980, Radiocarbon (22) 647-654
The effects of nonconservative sources (inputs) and sinks (outputs) of carbon are indicated by the behavior of Δ14C and δ13C of the total dissolved inorganic carbon (ΣCO2) in San Francisco Bay and Chesapeake Bay. Isotopic distributions and model calculations indicate that in North San Francisco Bay the net CO2 flux to...

At least once this episodic lake briefly contained half the of water that catastrophically drained the largest glacial Lakes Missoula. Evidence that the...
A model to forecast short-term snowmelt runoff using synoptic observations of streamflow, temperature, and precipitation
Wendell V. Tangborn
1980, Water Resources Research (16) 778-786
Snowmelt runoff is forecast with a statistical model that utilizes daily values of stream discharge, gaged precipitation, and maximum and minimum observations of air temperature. Synoptic observations of these variables are made at existing low- and medium-altitude weather stations, thus eliminating the difficulties and expense of new, high-altitude installations. Four...

Impact of horse traffic on trails in Rocky Mountain National Park.
R.M. Summer
1980, Journal of Soil and Water Conservation (35) 85-87
Disturbances related to the impact of horses on trails in Rocky Mountain National Park vary across the landscape. Geomorphic monitoring of permanent sites suggests that horse traffic is not the single, dominant process active on trails, nor is degredation always a direct result of horse use. Instead, amounts and rates...
