Habitat Suitability Index Models: Great egret Habitat Suitability Index Models: Great egret
The great egret, also called common egret or American egret, is a large white heron tn the order Ciconiiformes, family Ardeidae. Great egrets stand 94.0-104.1 cm (37-41 inches) tall and have a wing spread to 139.7 cm (55 inches) (Terres 1980). The species is associated with streams, ponds, lakes, mud flats, swamps, ahd freshwater and salt marshes. The birds feed in shallow water on...

Reproduction by the endangered cui-ui in the lower Truckee River Reproduction by the endangered cui-ui in the lower Truckee River
Adult spawning behavior and emigration of larvae of the endangered cui-ui Chasmistes cujus were studied in a natural side channel of the lower Truckee River. External radio-tags placed on eight apparently did not affect spawning behavior. Cui-uis spawned in clusters of two to seven fish; usually a single female was flanked by two males. Each spawning act lasted 3–6 seconds, and...

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...

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...

Habitat suitability index models: redhead (wintering) Habitat suitability index models: redhead (wintering)
The redhead is a North American waterfowl species with economic as well as ecological importance. It is highly desired by hunters. Retrieved redhead kill in the United States averaged 143,000 birds during the three waterfowl seasons from 1975 to 1977 (U.S. Department of the Interior 1981a, 1981b). Populations on the principal breeding grounds of the redhead--the prairie and parkland...

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...
