A new database on contaminant exposure and effects in terrestrial vertebrates for natural resource managers A new database on contaminant exposure and effects in terrestrial vertebrates for natural resource managers
The Biomonitoring of Environmental Status and Trends (BEST) program of the Department of the Interior is focused to identify and understand effects of contaminant stressors on biological resources under their stewardship. Despite the desire of many to continuously monitor the environmental health of our estuaries, much can be learned by summarizing existing temporal, geographic, and...

Development of an IBI-based assessment of depressional wetlands in Maryland and Delaware Development of an IBI-based assessment of depressional wetlands in Maryland and Delaware
The hydrogeomorphic approach (HGM) of wetland assessment emphasizes functional components of wetlands such as water storage, transformation and cycling of elements, accumulation of sediments, and preservation of habitats. Many of the elements measured in HGM are physical rather than ecological or biological. The HGM approach, therefore, provides information on certain aspects of wetlands...

Semen collection and fertility in naturally fertile sandhill cranes Semen collection and fertility in naturally fertile sandhill cranes
Aviculturists often ask if semen collection will interfere with fertility in naturally fertile pairs of cranes. We used 12 naturally fertile Florida sandhill crane (Grus canadensis pratensis) pairs for this study, 6 control and 6 experimental. All pairs had produced fertile eggs in previous years and were in out-of-doors pens scattered throughout different pen complexes, within auditory...

Use of ultralight aircraft for introducing migratory crane populations Use of ultralight aircraft for introducing migratory crane populations
Objectives were to determine if captive-reared cranes could be led behind an ultralight aircraft (UL) along a migration route and, if after release on a wintering area, they would integrate with wild cranes and migrate north in spring to their natal area without assistance. Greater sandhill cranes (Grus canadensis tabida) were used as the research surrogate for whooping cranes (Grus...

Causes of Mississippi sandhill crane mortality in captivity 1984-95 Causes of Mississippi sandhill crane mortality in captivity 1984-95
During 1984-95, 111 deaths were documented in the captive flock of Mississippi sandhill cranes (Grus canadensis pulla) housed at the Paluxent Wildlife Research Center. Trauma was the leading cause of death (37%), followed by infectious/parasitic diseases (25%), anatomic abnormalities (15%), and miscellaneous (8%). No positive diagnosis of cause of death was found in 19% of the necropsies...

Fate of Airborne Contaminants in Okefenokee National Wildlife Refuge Fate of Airborne Contaminants in Okefenokee National Wildlife Refuge
Designation of Okefenokee National Wildlife Refuge as a Class I Air Quality Area (given the highest level of protection possible from air pollutants under the Clean Air Act Amendments of 1977) affords mandatory protection of the Refuge's airshed through the permit-review process for planned developments. Rainfall is the major source of water to the swamp, and potential impacts from...

The scientific bases for preservation of the Mariana crow The scientific bases for preservation of the Mariana crow
The Panel recently released the report and recommendations resulting from its work over the last six months. Although primarily focused on the Mariana Crow, the report highlights that this is a matter potentially far more serious than the preservation of the crow on Guam and Rota. The report includes major sections dealing with the need to intensify research and control activities on the...

Evaluation of semen from nondomestic birds Evaluation of semen from nondomestic birds
Aspects of poultry Al technology are applicable to nondomestic birds. However, modifications in the methods of semen collection, evaluation, and insemination are often necessary to accommodate either the bird's size, sperm numbers, or. female anatomy. This section provides a brief overview of procedures used to evaluate semen from nondomestic birds. Unless specified, materials, reagents...
