Internesting Movements Of Loggerhead (Caretta Caretta) Sea Turtles In Virginia, Usa, Katherine L. Mansfield, John A. Musick, Soraya M. Bartol Feb 2001

Internesting Movements Of Loggerhead (Caretta Caretta) Sea Turtles In Virginia, Usa, Katherine L. Mansfield, John A. Musick, Soraya M. Bartol

Reports

Virginia is the northern most nesting region regularly utilized by loggerhead sea turtles (Caretta caretta) along the eastern coast of the United States. Along the southern shoreline of Virginia, between two and ten nests have been recorded annually since 1989 within Back Bay National Wildlife Refuge and False Cape State Park. Since 1992, the Virginia Institute of Marine Science (VIMS) has attached eight satellite transmitters to nesting loggerhead sea turtles in order to monitor their interesting movements and falVwinter migrations. VIMS has tracked the same nesting loggerhead three separate times during the 1993, 1995 and 1997 nesting seasons. This turtle ...


Polychaete Key For Chesapeake Bay And Coastal Virginia, Aaron Bartholomew, Virginia Institute Of Marine Science Jan 2001

Polychaete Key For Chesapeake Bay And Coastal Virginia, Aaron Bartholomew, Virginia Institute Of Marine Science

Reports

Polychaetes are a class of annelid worms, generally marine, with more than 10,000 species. Common representatives include the lugworm (Arenicola marina) and the sandworm or clam worm Nereis. Polychaetes are important members of benthic ecosystems, serving as food for other organisms and playing a key role in mixing sediments. This key is designed to help identify polychaete species in Chesapeake Bay and coastal Virginia.


Bibliography Of The Monogenetic Trematode Literature Of The World, 1758 To 1982, William J. Hargis Jr., Dennis A. Thoney May 1983

Bibliography Of The Monogenetic Trematode Literature Of The World, 1758 To 1982, William J. Hargis Jr., Dennis A. Thoney

Reports

Interest in the monogenean parasites has grown markedly in the last twenty years. To enhance and speed world-wide research activity, we prepared the first edition of this bibliography in 1969. This latest effort is intended to do the same.


Dorsal And Anal Pterygiophore Interdigitation Patterns In Four Species Of Morone (Teleostei, Percichthyidae) : An Aid To Larval Identification, John E. Olney, George C. Grant, Fred E. Schultz, C. Laurence Cooper, John Hageman Jan 1983

Dorsal And Anal Pterygiophore Interdigitation Patterns In Four Species Of Morone (Teleostei, Percichthyidae) : An Aid To Larval Identification, John E. Olney, George C. Grant, Fred E. Schultz, C. Laurence Cooper, John Hageman

Reports

The diagnostic potential of dorsal and anal pterygiophore interdigitation patterns was examined in larval stages of Morone saxatilis, M. chrysops, M. americana and M.mississippiensis. The number and position of pterygiophores relative to interneural spaces 1-6 and 10-13 and interhaemal spaces 12-15 as well as total number of dorsal and anal pterygiophores are characters useful in delimiting larvae of American Morone species. Interdigitation patterns useful in separating M. mississippiensis and M. americana larvae were not found, however these two species may not co-occur.


A Check List Of The Biota Of Lower Chesapeake Bay : With Inclusions From The Upper Bay And The Virginian Sea, Marvin L. Wass Oct 1972

A Check List Of The Biota Of Lower Chesapeake Bay : With Inclusions From The Upper Bay And The Virginian Sea, Marvin L. Wass

Reports

The biota of Chesapeake Bay seems generally less known than that of New England and much of our West Coast. The present work attempts to mollify this discrepancy. The compilation has been revised and expanded to include plants and vertebrates. Inclusion of creatures not strictly aquatic but which may occasionally found their areas flooded by tidal waters has necessitated subjective declsions of limitation.


A Study Of The Zooplankton Of Lower Chesapeake Bay : Nsf-Rann Annual Report, 1972, George C. Grant Jan 1972

A Study Of The Zooplankton Of Lower Chesapeake Bay : Nsf-Rann Annual Report, 1972, George C. Grant

Reports

Studies of zooplankton are necessary to any broader investigation of aquatic ecosystems. In estuaries such as the Chesapeake Bay, zooplankton function as both detritus feeders. and primary consumers of phytoplankton. Some of them, including chaetognaths, medusae and large copepods, are members of a higher trophic level. The diversity of zooplankton, especially in neiitic areas, contributes to the complexities of' such studies.

The present project was initiated wholly as a result of the interest of the National Science Foundation in Chesapeake Bay and the establishment of the Chesapeake Research Consortium. The design of the research was planned to integrate with ongoing ...


Bibliography On The Scyphozoa With Selected References On Hydrozoa And Anthozoa, Dale R. Calder, Harold N. Cones, Edwin B. Joseph Jan 1971

Bibliography On The Scyphozoa With Selected References On Hydrozoa And Anthozoa, Dale R. Calder, Harold N. Cones, Edwin B. Joseph

Reports

Our goal in assembling this bibliography has been to bring together literature references on all aspects of scyphozoan research. Compilation was begun in 1967 as a card file of references to publications on the Scyphozoa; selected references to hydrozoan and anthozoan studies that were considered relevant to the study of scyphozoans were included. In 1968, a major research program on the jellyfish of Chesapeake Bay was initiated at the Virginia Institute of Marine Science (VIMS) under Dr. E. B. Joseph, and work on the bibliography became an integral part of the program. In 1969 we began converting the bibliography into ...


Bibliography Of The Monogenetic Trematode Literature Of The World, 1758 To 1969, W. J. Hargis Jr., A. R. Lawler, R. Morales-Alamo, D. E. Zwerner Sep 1969

Bibliography Of The Monogenetic Trematode Literature Of The World, 1758 To 1969, W. J. Hargis Jr., A. R. Lawler, R. Morales-Alamo, D. E. Zwerner

Reports

In preparing this bibliography we have attempted to collect all literature references pertaining to the Monogenea. Accordingly it represents an up-to-date (through September 1969) guide to the literature of these parasites, and is of maximum scope, including not only taxonomic literature but also references to ecological and physiological studies on Monogenea as well as reports of preferred methods of treating infestations of these parasites.
