The effects of meiofauna on settling macrofauna: meiofauna may structure macrofaunal communities The effects of meiofauna on settling macrofauna: meiofauna may structure macrofaunal communities
When macrofaunal larvae and juveniles recruit into the benthos, they are in the same size category as the meiofauna. These small size classes have been consistently ignored in macrofaunal studies despite the increasingly accepted idea that communities are structured not only by interactions between adults, but also by interactions which occurred when the animals were young and in the...

Accumulation, sublethal effects, and safe concentration of a refined oil as evaluated with cutthroat trout Accumulation, sublethal effects, and safe concentration of a refined oil as evaluated with cutthroat trout
Cutthroat trout (Salmo clarki) were exposed for 90 days in the laboratory to a refined oil collected from the North Platte River at a seepage site below the American Oil Company refinery at Casper, Wyoming. Fish were exposed to five concentrations and a control, and seven biological responses (survival, growth, gill pathology, liver pathology, caudal fin erosion, caudal fin pathology and...

The role of the USFWS geographic information system in coastal decisionmaking The role of the USFWS geographic information system in coastal decisionmaking
Unprecedented demand on coastal resources in the 1980's has generated a need for valid information and analyses to support wise management of the coastal zone. The National Coastal Ecosystems Team of the U.S. Fish and Wildlife Service recently implemented a geographic information system to enhance its ability to analyze and display environmental information about the coastal zone...

Hydrology of area 38, Western Region, Interior Coal Province, Iowa and Missouri Hydrology of area 38, Western Region, Interior Coal Province, Iowa and Missouri
A nationwide need for information characterizing hydrologic conditions in mined and potential mine areas has become paramount with the enactment of the Surface Mining Control and Reclamation Act of 1977. This report is designed to be useful to the mine owners, operators, and others by presenting information about the existing hydrologic conditions and by identifying sources of hydrologic

Some observations on the ecology and fish management of reservoirs in the United States Some observations on the ecology and fish management of reservoirs in the United States
By 1980 there were 1,608 reservoirs (over 202 ha each) with a surface area of 4 million ha in the United States. Construction of new reservoirs has decreased in recent years because of the lack of suitable sites and the opposition of environmental interests. Reservoirs have characteristics of both lacustrine and riverine ecosystems. Reservoirs have been segmented into riverine...
