Habitat Suitability Index Models: Southern red-backed vole (western United States)
Arthur W. Allen
1983, FWS/OBS 82/10.42
Habitat preferences of the southern red-backed vole (Clethrionomys gapperi) are described in this publication, which is one of a series of Habitat Suitability Index (HSI) models. A review and synthesis of the literature is followed by development of a model of the species-habitat requirements of the southern red-backed vole. Habitat suitability...
Habitat Suitability Index Models: Mottled duck
James C. Rorabaugh, Phillip J. Zwank
1983, FWS/OBS 82/10.52
The mottled duck is a mallard-like resident species of the Gulf of Mexico coast, from the marshes of Pearl River on the Lou i si ana-Ht ss t ss ipp i border to the Al varado Lagoon near Veracruz, Mexico (Bell rose 1976). The highest densities of nesting mottl ed...
Habitat Suitability Index Models: Baird's sparrow
Patrick J. Sousa, W. Neil McDonal
1983, FWS/OBS 82/10.44
A review and synthesis of existing information were used to develop a habitat model for Baird's sparrow. The model is scaled to produce an index of suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for Baird's sparrow habitat in the Northern Great Plains. Habitat suitability indices are designed...
Habitat Suitability Index Models: Gulf of Mexico American Oyster
Edwin W. Cake Jr.
1983, FWS/OBS 82/10.57
The American or eastern oyster (Crassostrea virrinica [Gmelin]), a bivalve in the family Ostreidae, is an important commercia and recreational species along the Atlantic and Gulf of Mexico coasts of North America and other areas (U.S. Pacific coast and Hawaii) where it has been introduced (Galtsoff 1964). It evolved over...
Habitat Suitability Index Models: Coho salmon
Thomas E. McMahon
1983, FWS/OBS 82/10.49
The coho salmon (Oncorhynchus kisutch) is native to the northern Pacific Ocean, spawning and rearing in streams from Monterey Bay, California, to Point Hope, Alaska, and southward along the Asiatic coast to Japan. Its center of abundance in North America is from Oregon to Alaska (Briggs 1953; Godfrey 1965; Hart...
Habitat Suitability Index Models: Clapper rail
James C. Lewis, Russell L. Garrison
1983, FWS/OBS 82/10.51
A review and synthesis of existing information were used to develop a model suitable for evaluating the quality of coastal habitat of clapper rails (Rallus longirostris). The model is scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for coastal areas of...
Habitat Suitability Index Models: Williamson's sapsucker
Patrick J. Sousa
1983, FWS/OBS 82/10.47
The Williamson's sapsucker (Sphyrapicus thyroideus) " ... inhabits middle elevation pine forests and high elevation spruce-fir forests" (Crockett 1975:111) as well as aspen stands (Hansley 1977; Hansley, pers. comm.) throughout its range in the western Uni ted States. The Rocky Mounta in subspecies (S. t. nataliae) exhibits altitudinal and latitudinal...
Species Profiles: Life histories and environmental requirements (Gulf of Mexico): Brown shrimp
Dennis R. Lassuy
1983, FWS/OBS 82/11.1
Species profiles are literature summaries on the taxonomy, morphology, range, life history, and environmental requirements of coastal aquatic species. They are designed to assist in environmental impact assessment. The brown shrimp, Penaeus aztecus, is the major species in the Gulf of Mexico shrimp fishery, the most valuable $302 million in...
Habitat Suitability Index Models: Bigmouth buffalo
Elizabeth A. Edwards
1983, FWS/OBS 82/10.34
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Bigmouth buffalo (Ictiobus cyprinellus), a freshwater fish. The models are scaled to produce an indices of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for freshwater areas of the...
Biology, population structure, and estimated forage requirements of lake trout in Lake Michigan
Gary W. Eck, LaRue Wells
1983, Technical Paper 111
Data collected during successive years (1971-79) of sampling lake trout (Salvelinus namaycush) in Lake Michigan were used to develop statistics on lake trout growth, maturity, and mortality, and to quantify seasonal lake trout food and food availability. These statistics were then combined with data on lake trout year-class strengths and...
Habitat Suitability Index Models: Field sparrow
Patrick J. Sousa
1983, FWS/OBS 82/10.62
Habitat preferences of the field sparrow (Spizella pusilla) are described in this report, which is one of a series of Habitat Suitability Index (HSI) models. A review and synthesis of the literature is followed by the development of a habitat model for the field sparrow throughout its breeding range in...
Habitat Suitability Index Models: Longnose dace
Elizabeth A. Edwards, Hiram Li, Carl B. Schreck
1983, FWS/OBS 82/10.33
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for longnose dace (Rhinichthys cataractae), a freshwater fish. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for freshwater, marine and estuarine areas...
