Molecular and immunogenetic analysis of major histocompatibility haplotypes in Northern Bobwhite enable direct identification of corresponding haplotypes in an endangered subspecies, the Masked Bobwhite Molecular and immunogenetic analysis of major histocompatibility haplotypes in Northern Bobwhite enable direct identification of corresponding haplotypes in an endangered subspecies, the Masked Bobwhite
The major histocompatibility complex (MHC) is a group of genetic loci coding for haplotypes that have been associated with fitness traits in mammals and birds. Such associations suggest that MHC diversity may be an indicator of overall genetic fitness of endangered or threatened species. The MHC haplotypes of a captive population of 12 families of northern bobwhites (Colinus virginianus)...

Evaluation of mist-net sampling as an index to productivity in Kirtland's Warblers Evaluation of mist-net sampling as an index to productivity in Kirtland's Warblers
Many applied and theoretical investigations require information on how productivity varies in time and space (Temple and Wiens 1989. DeSante 1995). Examples include studies of habitat quality, population trends, life-history tactics, and metapopulation dynamics. From a demographic perspective, productivity is the number of young counted at a given time of year, produced per adult (e.g...

Density and habitat of breeding Swallow-tailed Kites in the lower Suwannee ecosystem, Florida Density and habitat of breeding Swallow-tailed Kites in the lower Suwannee ecosystem, Florida
Historically the Swallow-tailed Kite (Elanoides forficatus) bred in the United States in at least 16 eastern states. Currently it is restricted to seven southeastern states, with most of its breeding range in Florida. Breeding Bird Surveys indicate a declining trend for this Neotropical migrant in most of Florida. Using a rapid survey technique at the Lower Suwannee NWR on 25-27 Mar...

Case 3058. Arctocephalus F. Cuvier, 1826 and Callorhinus Gray, 1859 (Mammalia, Pinnipedia): Proposed conservation by the designation of Phoca pusilla Schreber, [1775] as the type species of Arctocephalus; and Otaria Peron, 1816 and Eumetopias Gill, 1866 Case 3058. Arctocephalus F. Cuvier, 1826 and Callorhinus Gray, 1859 (Mammalia, Pinnipedia): Proposed conservation by the designation of Phoca pusilla Schreber, [1775] as the type species of Arctocephalus; and Otaria Peron, 1816 and Eumetopias Gill, 1866
The purpose of this application is to conserve the accustomed understanding and usage of the fur seal name Arctocephalus F. Cuvier, 1826 by the designation of Phoca pusilia Schreber, [1775] as the type species, thus conserving also the name Callorhinus Gray, 1859. At present Phoca ursina Linnaeus, 1758 is the valid type species of both Arctocephalus and Callorhinus. The name...

Hydrogeologic investigations by the U.S. Geological Survey at the former Fort Benjamin Harrison, Marion County, Indiana Hydrogeologic investigations by the U.S. Geological Survey at the former Fort Benjamin Harrison, Marion County, Indiana
As part of the U.S. Department of Defense Base Realignment and Closure process, the former Fort Benjamin Harrison in Marion County, Indiana (called 'Fort Harrison' in this fact sheet), was placed on the Base Closure List in 1991. Property disposal and reuse activities began when Fort Harrison was decommissioned in 1995; work continues through 1999. Fort Harrison was located on...

Fish-community composition in Cowanesque River upstream and downstream of the Cowanesque Dam, Tioga County, Pennsylvania, 1998 Fish-community composition in Cowanesque River upstream and downstream of the Cowanesque Dam, Tioga County, Pennsylvania, 1998
Between February 1997 and September 1997, 10 monitor wells were drilled near the site of the former Naval Air Warfare Center, Warminster, Bucks County, Pa., to monitor water levels and sample ground-water contaminants in the shallow, intermediate, and deep water-bearing zones. The sampling will determine the horizontal and vertical distribution of contaminated ground water migrating from...

Record Extension and Streamflow Statistics for the Pleasant River, Maine Record Extension and Streamflow Statistics for the Pleasant River, Maine
Historical streamflow data for the Pleasant River are limited to 11 years (from 1980 to 1991) at the U.S. Geological Survey streamgaging station near Epping. Analysis of these data in conjunction with flow data from other nearby stations indicates that the 11 years of record for the Pleasant River may not be representative of longer-term conditions in the basin. A correlation between the
