Effects of pulsed, high-velocity water flow on larval robust redhorse and V-lip redhorse Effects of pulsed, high-velocity water flow on larval robust redhorse and V-lip redhorse
The pulsed, high-velocity water flow characteristic of water-flow patterns downstream from hydropower-generating dams has been implicated in the declining abundance of both aquatic insects and fishes in dam-regulated rivers. This study examined the effects of 0, 4, and 12 h per day of pulsed, high-velocity water flow on the egg mortality, hatch length, final length, and survival of...

Use of retrospective data to assess ecotoxicological monitoring needs for terrestrial vertebrates residing in Atlantic coast estuaries Use of retrospective data to assess ecotoxicological monitoring needs for terrestrial vertebrates residing in Atlantic coast estuaries
The “Contaminant Exposure and Effects–Terrestrial Vertebrates” (CEE-TV) database contains 4,336 records of ecotoxicological information for free-ranging amphibians, reptiles, birds, and mammals residing in Atlantic and Florida Gulf coast estuaries and their drainages. To identify spatial data gaps, those CEE-TV records for which the specific study location were known (n=2,740) were...

Histories of Puerto Rican parrot nests in the Caribbean National Forest/Luquillo Experimental Forest, 1973-2000 Histories of Puerto Rican parrot nests in the Caribbean National Forest/Luquillo Experimental Forest, 1973-2000
This publication summarizes the histories of all known Puerto Rican parrot nests in the Caribbean National Forest/Luquillo Experimental Forest from 1973 through 2000. Included for each nest, when known, are the identifies of the pair, clutch size, known fertile and infertile eggs, number of eggs that hatched, number of chicks that survived, sources of mortality, fostering (source...

Estimation of change in populations and communities from monitoring survey data Estimation of change in populations and communities from monitoring survey data
Monitoring surveys provide fundamental information for use in environmental decision making by permitting assessment of both current population (or community) status and change in status, by providing a historical context of the present status, and by documenting response to ongoing management. Conservation of species and communities has historically been based upon monitoring...

Black ducks and their Chesapeake Bay habitats: Proceedings of a symposium Black ducks and their Chesapeake Bay habitats: Proceedings of a symposium
The symposium 'Black Ducks and Their Chesapeake Bay Habitats,' held October 4, 2000, provided a forum for scientists to share research about the American black duck (Anas rubripes), an important breeding and wintering waterfowl species dependent upon the Chesapeake Bay habitats. American black ducks have declined significantly in the last 50 years and continue to be a species of...
The U.S. Geological Survey and the Chesapeake Bay – The role of science in environmental restoration The U.S. Geological Survey and the Chesapeake Bay – The role of science in environmental restoration
The Chesapeake Bay is the Nation's largest estuary and historically supported one of the most productive fisheries in the world. In addition to supporting aquatic communities and wildlife, the bay's watershed serves the economic and recreational needs of 15 million people. The fertile soils of the watershed support significant agricultural production. Unfortunately, the commercial...

Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 2001 Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 2001
The Hollywood, Butler Island, and Wekiva Basin stations did not operate this year, but we welcome back Jekyll Island, GA, with its flagship species, Western Palm Warbler (835); and we are glad to have a report from Rock Springs Run State Reserve in Florida to replace the Wekiva Station. Except for a couple of good rains in August, the second half of the year was droughty in Maryland and...
