Fisheries Report No 38 - The Shark Bay Prawn Fishery (1970 - 1976), J. W. Penn, R. W. Stalker

Fisheries Research Reports

The existence of prawn stocks in Shark Bay, Western Australia, has been known since 1904 when the sailing ketch "Rip" on charter to the Western Australian Government, trawled large quantities of prawns from the area between Bernier Island and the mainland, Gale (1905). Although the Fisheries research vessel "Lancelin" trawled potentially commercial quantities of prawns from Shark Bay in the early 1950's, it was not until 1962 that a regular fishery was begun.

Today the prawn stocks of Shark Bay support Western Australia's largest and most consistent prawn fishery, having an annual production currently exceeding 2 000 tonnes. The catch …

Characterizing Flight Aggregation Of The Southern Pine Beetle, Jack E. Coster, Paul C. Johnson

Faculty Publications

Spatial aggregation patterns of flying southern pine beetles, Dendroctonus frontalis Zimm., were studied using a systematic grid of sticky flight traps placed in 3 beetle infestations. Five methods of characterizing dispersion were compared: Lloyd's index of patchiness (IP), Morisita's index of dispersion (15), the coefficient of dispersion (CD), the slope of

Taylor's power function (b) and the slope of Iwao's regression of mean crowding on mean density (m). All indices indicated a high degree of aggregation of flying southern pine beetles within the infestations. The indices varied, however, in their ranking of aggregation for the 3 study sites. IP and …

A Taxonomic And Distributional Study Of The Crayfishes (Decapoda: Cambaridea) Of West Virginia With Diagnostic Keys To Species Of The Genera Cambarus And Orconectes, Steven M. Lawton

Theses, Dissertations and Capstones

This thesis is the first extensive investigation of West Virginia's crayfishes since Newcombe (1929) surveyed the state's fauna 50 years ago. Records, collections, and specimens were obtained from the 7 drainage areas of the state. Crayfish were collected from early spring through the fall of 1978. Both aquatic species and burrowers were included in the study. Presently, seventeen species and subspecies are known to exist in West Virginia. The genus Cambarus contains 10 of the total species of which three are primary burrowers. Cambarus nerterius, from the cavernous Greenbrier and Pocahontas counties of the Greenbrier River drainage, is the state's …

A New Species Of Cerapus Say, 1817 (Crustacea: Amphipoda) From The Northern Gulf Of Mexico, With Notes On Its Ecology, James Darwin Thomas, Richard W. Heard

Marine & Environmental Sciences Faculty Articles

During research in coastal marshes of the Mississippi Delta region in 1975, a large, undescribed amphipod belonging to the genus Cerapus was discovered in tidal channels. This new species, C. benthophilus, is characterized by its large size and 7-12 segmented antennal flagella. Habitat preference is muddy silt bottoms upon which it constructs conspicuous mats or "tufts" of interwoven tubes in shallow coastal bays and marshes from Louisiana to the panhandle areas of northern Florida.

A Redescription Of The Wood-Rasping Amphipod Trophichelura Gomezi Ortiz, 1976 (Cheluridae) From The Florida Keys, With Notes On Its Distribution And Ecology, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

The wood-rasping amphipod, Tropichelura gomezi Ortiz, 1976, is redescribed from the Florida Keys to include diagnostic characters omitted in the original description. Morphological characters and distributional patterns of T. gomezi are compared with those of the other member of the genus, Tropichelura insulae (Caiman, 1910). Laboratory studies show that T. gomezi defends its burrow entrance from other members of its species, but tolerates the presence of limnoriid isopods with which it cooccurs. A lectotype for Tropichelura insulae is designated .

Analysis And Synthesis Of The Dynamic Response Of Retinal Neurons, Scott E. Brodie

Student Theses and Dissertations

The theory of linear systems analysis is developed in a form directly applicable to the treatment of the Limulus retina. The dynamics of the retina may conveniently be characterized by means of a spatiotemporal transfer function, which summarizes the response of the system to moving sinusoidal gratings ("analysis"). The response of the retina to an arbitrary stimulus may then be calculated by addition of the response to suitably weighted sinusoidal stimuli ("synthesis"). Responses were obtained from the in-situ retina by means of extracellular recording of impulse activity in single optic nerve fibers. Test ommatidia were chosen in the interior of …

Early Events In The Biosynthesis And Subcellular Consignment Of Secretory And Membrane Proteins, Vishwanath R. Lingappa

Student Theses and Dissertations

The biosynthetic mechanisms responsible for the segregation of secreted proteins and for the insertion of integral membrane proteins have been examined in light of the signal hypothesis. Model systems for the study of the biosynthesis of these different classes of proteins, as well as for the study of specific events common to both, have been developed. Their common as well as distinctive features have been probed by a variety of different experimental approaches involving cell free protein synthesizing systems supplemented with heterologous microsomal membranes either during or after translation: a) proteolytic enzymes, SDS-PAGE and autoradiography have been used to characterize …

Probing Mitotic Chromosome Structure And Arrangement Using Micromanipulation, Bruce R. Korf

Student Theses and Dissertations

The Indian deer, (Muntiacus muntjak), has the lowest known diploid chromosome number (seven in the male) for a mammal. Mitotic chromosomes can be removed from cells either by extraction with microneedles or by inducing chromosome expulsion with a drop of silicone oil applied to the cell. The entire diploid complement is removed by virtue of interconnecting fibers among the chromosomes. The chromosomes are brought to the surface of the cover slip for analysis, where each can be identified morphologically with phase contrast optics. The chromosomes are sticky and extensible, and parts of chromosomes can be dissected by cutting with microneedles. …

Studies On Chloroplast Protein Synthesis In Vivo And In Vitro, Karl Stanley Matlin

Student Theses and Dissertations

Protein synthesis in the Chlamydomonas reinhardtii chloroplast was investigated by in vivo and in vitro approaches. The site of synthesis of chloroplast proteins was examined to determine how many proteins were synthesized inside the chloroplast. Cells were labeled in vivo with [³⁵S]-sulfate in the presence of either. chloroplast or cytoplasmic protein synthesis inhibitors, and fractionated into soluble proteins, thylakoid membranes, and chloroplast ribosomal subunits. The use of high specific activity sulfate and improved gel electrophoretic techniques were key features of this study because they permitted minor chloroplast products to be detected for the first time. It was determined …

Ryegrass Toxicity Organism Found On Other Grasses, D L. Chatel, J. L. Wise, A. G. Marfleet

Journal of the Department of Agriculture, Western Australia, Series 4

Yellow slime disease caused by Corynebacterium sp. has recently been found in three grass species.

The diseased grasses were found in the field growing with each other and with affected toxic annual ryegrass.
