Forested wetlands of the Southeast: Review of major characteristics and role in maintaining water quality
Parley V. Winger
1986, Resource Publication 163
Forested wetlands occupying floodplains of major rivers in the Southeast are highly productive and diverse ecological systems. The wetlands are produced and maintained by fluvial processes and unique hydrologic regimes consisting of periodic flooding and subsequent drydown. Fluctuations in soil chemistry and biology resulting from this flooding and...
Use of miniroutes and Breeding Bird Survey data to estimate abundance
C.S. Robbins, B.A. Dowell
1986, Book chapter, Proceedings of the Second Northeastern Breeding Bird Atlas Conference
1. Information on relative abundance is easily obtained and adds greatly to the value of an atlas project. 2. The Breeding Bird Survey (BBS) provides annual counts (birds per 50 roadside stops) that can be used to: (1) map relative abundance by physiographic region within a state or province,...

1986, Book chapter, The Pleasures of Watching Birds
Introduction
M.R. Fuller
S.E. Senner, C.M. White, J.R. Parrish, editor(s)
1986, Book chapter, Raptor Conservation in the Next 50 Years
Conservation of migratory raptors: An overview based on fifty years of raptor banding
C.S. Robbins
S.E. Senner, C.M. White, J.R. Parrish, editor(s)
1986, Book chapter, Raptor Conservation in the Next 50 Years
During the 50-year period 1931-80, 422,000 raptors were banded in the United States and Canada. Encounter rates were calculated, by decades of banding, for all birds reported outside of the l0-min block of latitude and longitude where they had been banded. Encounter rates for the various raptor species decreased from...
Aquatic birds and selenium in the San Joaquin Valley
Harry M. Ohlendorf
1986, Book chapter, Selenium and agricultural drainage: Implications for San Francisco Bay and the California environment - Proceedings of the second selenium symposium
Kesterton Reservoir is a series of ponds comprising 1,200 acres sitting in the grasslands of the Kesterton National Wildlife Refuge. It is bounded on the east by the San Luis Drain, a concrete-lined canal that discharges agricultural drainage into the ponds at their southern end, from which point it then...
Genetic management of captive masked bobwhites

M.R. Stromberg, R. B. Johnson, S.W. Hoffman, editor(s)
1986, Book chapter, Masked Bobwhite Biology and Conservation: Proceedings of a symposium, University of Arizona, Tuscon, Arizona, December 6, 1984
Immunosuppressive effects of lead
J. Christian Franson
J.Scott Feierabend, A.Brooke Russell, editor(s)
1986, Book chapter, Lead poisoning in wild waterfowl - A workshop
Immunosuppressive effects of lead were reported as early as 1966, when it was noted that lead increased the sensitivity of rats to bacterial endotoxins (Selye et al. 1966). Since then a substantial body of literature has demonstrated adverse effects of lead on the immune system in a variety of laboratory...
Habitat Suitability Index Models: Slider turtle
Stephen J. Morreale, J. Whitfield Gibbons
1986, FWS/OBS 82/10.125
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the slider turtle (Pseudemys scripta). The model consolidates habitat use information into a framework appropriate for field application and is scaled to produce an index between 0.0 (unsuitable habitat) and 1.0 (optimum...
Habitat Suitability Index Models: Wildlife species richness in shelterbelts
Richard L. Schroeder
1986, FWS/OBS 82/10.128
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for evaluating potential species richness in shelterbelts. The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0...
Habitat Suitability Index Models and Instream Flow Suitability Curves: Shortnose sturgeon
Johnie H. Crance
1986, FWS/OBS 82/10.129
A review and synthesis of existing information were used to develop habitat suitability index models and instream flow suitability curves for the shortnose sturgeon (Acipenser brevirostrum). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat)...
