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...

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...

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...

Lower to middle Eocene sequences of the New Jersey coastal plain and their significance for global climate change Lower to middle Eocene sequences of the New Jersey coastal plain and their significance for global climate change
Boreholes from Island Beach, Allaire, Atlantic City, and Mays Landing, NJ provide an excellent chronology of lower to middle Eocene passive margin sequences and allow analysis of long-term sea-level changes and sedimentation patterns. These New Jersey sequences are tied directly to the geomagnetic polarity time scale through magnetostratigraphy. Integrated stratigraphy (including

Sediment transport pathway in the back of a nearly semienclosed subembayment of San Francisco Bay, California Sediment transport pathway in the back of a nearly semienclosed subembayment of San Francisco Bay, California
Time series measurements of current velocity, depth and suspended-solids concentration (SSC) were used to obtain suspended-solids fluxes (SSF) during the fall at central Honker Bay and Spoonbill Creek. A wind-induced shear stress increases SSF out of Honker Bay through Spoonbill Creek by combining two effects: (1) wind-wave resuspension of bed sediments, and (2) wind shear raises the...

The loss of hyperosmoregulatory ability in migrating juvenile American shad, Alosa sapidissima The loss of hyperosmoregulatory ability in migrating juvenile American shad, Alosa sapidissima
Investigations on juvenile American shad (Alosa sapidissima) revealed several physiological changes associated with downstream migration. Plasma chloride decreased 20% in wild juvenile shad during the autumn migration. Migrants had lower condition factor and hematocrit than non-migrant shad captured by beach seining. Gill Na + ,K + -ATPase activity of migrant shad was higher than non...

Anthropogenic molecular markers: Tools to identify the sources and transport pathways of pollutants Anthropogenic molecular markers: Tools to identify the sources and transport pathways of pollutants
The activities of modern civilization have released to the oceans a wide variety of both mobilized natural compounds and synthetic compounds not found prior to modern times. Many of these compounds provide a means of identifying sources of inputs and pathways of movement of chemicals through oceanic ecosystems and serve as molecular markers of human activities. A coastal ocean (Tokyo Bay...
