The Phylum Chaetognatha : A Bibliography, Grant C. George
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 …
Larvae And Relationships Of Epinepheline Serranids (Teleostei: Percoidei), Carole Christine Baldwin
Larvae And Relationships Of Epinepheline Serranids (Teleostei: Percoidei), Carole Christine Baldwin
Dissertations, Theses, and Masters Projects
Morphology is described for larvae of Diploprion bifasciatus, Belonoperca chabanaudi, Jeboehlkia gladifer, and Grammistes sexlineatus of the serranid subfamily Epinephelinae. Known larvae of all epinephelines are compared. Larval epinephelines differ in patterns of pigmentation, head spination, sequence of fin formation and morphology of elongate (often spectacularly so!) dorsal-fin spines. Relationships among epinepheline genera are investigated based on phylogenetic analysis of larval and adult morphology. Five monophyletic tribes are cladistically delineated, and relationships among tribes and among genera of the tribe Grammistini are hypothesized. Generic composition of tribes differs from Johnson's (1983) classification only in the allocation of Jeboehlkia to the …
Foraging Ecology Of The Blue Crab, Callinectes Sapidus Rathbun, In Lower Chesapeake Bay, Randa A. Mansour
Foraging Ecology Of The Blue Crab, Callinectes Sapidus Rathbun, In Lower Chesapeake Bay, Randa A. Mansour
Dissertations, Theses, and Masters Projects
This study concurrently quantified blue crab feeding habits and preference, and examined the inter-relationships between diet, predator preference, and predator and prey abundance and distribution in three subestuaries of lower Chesapeake Bay--the James, York and Rappahannock Rivers, Virginia. Complementary laboratory investigations estimated the combined effect of the functional, aggregative and interference responses upon prey and predator survival and predator foraging rates for blue crabs and a common bivalve prey, Macoma balthica, in this system. Crab abundance, prey abundance and diet were correlated such that blue crabs aggregated in areas of highest preferred (i.e., bivalve) prey abundance, as determined through electivity …
Comparative Biology And Population Dynamics Of Searobins (Genus Prionotus) With Emphasis On Populations In The Northwestern Gulf Of Mexico, James G. Hoff Jr
Comparative Biology And Population Dynamics Of Searobins (Genus Prionotus) With Emphasis On Populations In The Northwestern Gulf Of Mexico, James G. Hoff Jr
Dissertations, Theses, and Masters Projects
Eight species of Prionotus, collected from 5-100 m in the Gulf of Mexico along a cross-shelf transect off Freeport, Tx during October 1977-August 1981, were studied to determine life history patterns and how they partition resources. Only four species were abundant: P. tribulus, P. paralatus, P. longispinosus, and P. stearnsi. Prionotus spp. mature at 80 mm (P. stearnsi and P. rubio), 85 mm (P. tribulus and P. paralatus), 100 mm (P. ophryas), 105 mm (P. roseus), and 120 mm (P. longispinosus). Sizes at Age 1 were 99-140 mm (P. tribulus), 99-138 mm (P. longispinosus), 98-122 mm (P. paralatus), 75-125 mm …
