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.


The Phylum Chaetognatha : A Bibliography, Grant C. George Jan 1992

The Phylum Chaetognatha : A Bibliography, Grant C. George

Reports

This bibliography has resulted from an initial suggestion by Sargay Timofeev in the March 1990 newsletter of The Chaetognath Group, whose coordinator (Helga Kapp) further suggested that I be given the task. Both are forgiven. The eventual size of the task was unsuspected at its beginning in the fall of 1990; bibliographies are easily begun but decisions on their limits and conclusion are difficult. I have attempted to include all major and substantive works on the Chaetognatha. The inevitable omissions are inadvertent, although a recognized deficiency of the work lies in an incomplete listing of Russian references; I have included ...

Hydrodynamic Aspects Of Shark Scales, William G. Raschi, John A. Musick Jan 1984

Hydrodynamic Aspects Of Shark Scales, William G. Raschi, John A. Musick

Reports

The energetics of fish locomotion depends on a balance between thrust and drag. The interest stimulated by "Gray's Paradox", that is the seeming lack of sufficient power to overcome many of the estimated values of drag, has resulted in the delineation of a number of potential drag reducing mechanisms (Webb, 1975). Of particular interest is a variety of structural mechanisms, such as scombroid scale corselets (Walters, 1962) and scale ctenii (Burdak, 1969; Bone, 1972), which increase surface roughness and thereby alter boundary layer characteristics. Elasmobranch placoid scales, or dermal denticles, may perform such a function. Bone and Howarth (1966 ...

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.

Ontogenesis And Phylogenetic Interrelationships Of Parasitic Flatworms, Boris E. Bychowsky Jan 1981

Ontogenesis And Phylogenetic Interrelationships Of Parasitic Flatworms, Boris E. Bychowsky

Reports

The purpose of this report is to establish relationship among individual groups of parasitic flatworms, namely, among monogenetic trematodes (Monogenea), digenetic trematodes (Digenea), tapeworms proper (Cestoda), and the so-called Cestodaria group (AMPHILINIDAE and GYROCGTYLIDAE). The attempt to establish the above-mentioned relationships is made to a variable degree for different groups. The main point of this report is the establishment of phylogenetic relationship in the Monogenea, not only for the entire group as a whole, but also for the individual families which are members of this group. We feel that another important point is our attempt at clarifying the phylogenetic position ...


Morphology Of Udonella Caligorum Johnston, 1835, And The Position Of Udonellidae In The Systematics Of Platyhelminths, A. V. Ivanov Jan 1981

Morphology Of Udonella Caligorum Johnston, 1835, And The Position Of Udonellidae In The Systematics Of Platyhelminths, A. V. Ivanov

Reports

The platyhelminth, Udonella, lives on parasitic copepod crustaceans and, according to the present system of classification belongs to monogenetic trematodes (Monogena) among which it is usually placed in the group Monopisthocotylea (Fuhrmann, 1928; Bychowsky, 1937; Dawes, 1946; Sproston, 1946). However, the morphology of Udonella has not yet been studied thoroughly by anyone, and a number of unusual features of the structure, ontogenesis and biology of this form cause doubts with regard to its belonging to the Monogena.

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 ...

A survey was made in southern Chesapeake Bay and its tributaries from April 1965 through March 1968 to determine the species of hydrozoans present, their seasonality and reproductive periodicities. This report discusses 43 hydroid and 27 medusa species known from the study area, of which 23 hydroids and 11 medusae have not previously been found in Chesapeake Bay. Clytia paulensis and the hydroid of Moerisia lyonsi have not been reported before in North American waters, and the hydroid of Amphinema dinema is recorded for the first time from the western Atlantic. The present records extend the northern range of one ...


The Distribution And Ecology Of The Gammaridea (Crustacea : Amphipoda) Of The Lower Chesapeake Estuaries, James Feely, Marvin L. Wass Jan 1971

The Distribution And Ecology Of The Gammaridea (Crustacea : Amphipoda) Of The Lower Chesapeake Estuaries, James Feely, Marvin L. Wass

Reports

Gammarid amphipods of three tidal rivers entering Chesapeake Bay were studied for ten months, particularly in the York River where 40 species were record during the period. Several species moved up or down the rivers with changing salinity. The more abundant species had longer breeding seasons. The number of described species from lower Chesapeake Bay is now 42 and the presence of 10 undescribed species and of several which bracket the region indicates that much remains to be learned about amphipods in the Bay. Nineteen of these have a boreal affinity and seven are limited to the Virginian subprovince. A ...

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 ...
