The migratory population of striped bass (Morone saxatilis) (>400 mm total length[TL]) spends winter in the Atlantic Ocean off the Virginia and North Carolina coasts of the United States. Information on trophic dynamics for these large adults during winter is limited. Feeding habits and prey were described from stomach contents of 1154 striped bass ranging from 373 to 1250 mm TL, collected from trawls during winters of 1994-96, 2000, and 2002-03, and from the recreational fishery during 2005-07. Nineteen prey species were present in the diet. Overall, Atlantic menhaden (Brevoortia tyrannus) and bay anchovy (Anchoa mitchilli) dominated the diet by boimass (67.9%) and numerically (68.6%). The percent biomass of Atlantic menhaden during 1994-2003 to 87.0% during 2005-07. Demersal fish species such as Atlantic croaker (Micropogonias undulatus) and spot (Leiostomus xanthurus) represented <15% of the diet biomass, whereas alosines (Alosa spp.) were rarely observed. Invertebrates were least important, contributing <1.0% by biomass and numerically. Striped bass are capable of feeding on a wide range of prey sizes (2% to 43% of their total length). This study outlines the importance of clupeoid fishes to striped bass winter production and also shows that predation may be exerting pressure on one of their dominant prey, the Atlantic menhaden.

All abalones belong to the genus Haliotis sensu latu, family Haliotidae. The 75 species known worldwide (Booloot ian et, al. 1962) are anatomically similar and all are adapted for attachment to hard substrates. Seven species are widely distributed along the coast of California (Cox 1962; Mottet 19781, of which several are important in the comercial and sport fisheries of the Pacific Southwest.

This report summarizes the results of a characterization of chemical contaminants in the sediments in southwest Puerto Rico. The report is part of a project to integrate various analytical specialties to assess linkages between chemical contaminants and the condition of coral reefs. In this phase of the project, over 120 chemical contaminants were analyzed in sediments collected, including a number of organic (e.g., hydrocarbons), inorganic (e.g., metals), and biological (bacterial) compounds/analytes. The report also provides a preliminary analysis of the association between sediment contaminants and coral species richness. Overall, the levels of chemical contaminants in the study area between Guanica Bay and the town of La Parguera were fairly low. At most of the sites sampled, particularly adjacent to the town of La Parguera, concentrations of organic and inorganic contaminants were below the median values from NOAA’s National Status and Trends Program, which monitors the Nation’s coastal and estuarine waters for chemical contaminants. Elevated levels of a number of contaminant classes were seen at the two sites sampled within Guanica Bay. An initial analysis of modeled PAH (hydrocarbon) data and coral species richness (reef building species) indicated a strong negative correlation between the presence of PAHs in the sediments and coral species richness. Additional work is needed to assess possible reasons for this observed pattern. (PDF contains 126 pages).

The three areas in Rookery Bay, near Marco Island and Fakahatchee Bay were sampled from July 1971 through July 1972, and 1,006,640 individual animals were collected, of which the majority (55%) came from the Marco area. The large disparity between the catches at Marco and the remaining study areas was due mainly to the appearance of high numbers of species of polychaetes and echinoderms that were of very minor importance or absent from the catches in Rookery Bay and Fakahatchee Bay. When only the major classes of animals in the catch are considered (i.e., crustaceans, fish and mollusks) the total counts for Fakahatchee (298,830) and Marco (275,075) are quite comparable but both exceed Rookery Bay (119,388) by a considerable margin. The effects of the red tide outbreak in the summer of 1971 were apparently restricted to the Rookery Bay Sanctuary and may account for some of the observed differences. For the purposes of making controlled comparisons between the study areas, three common habitats were selected in each area so that a mud bottom habitat, a sand-shell bottom habitat and a vegetated bottom habitat were located in each of the study areas. Total catches by habitat types for crustaceans, fish and mollusks and certain of the more abundant species show clearly the overwhelming importance of the vegetated bottom as a habitat for animals. By habitat the vegetated areas had the most "indicator species" with five, the mud habitat was next with three and the sand-shell habitat third with two. Thus the vegetated habitat would be the best choice if a single habitat were to be used to detect environmental changes between study areas. (PDF contains 137 pages)

The Lake Elsinore quadrangle covers about 250 square miles and includes parts of the southwest margin of the Perris Block, the Elsinore trough, the southeastern end of the Santa Ana Mountains, and the Elsinore Mountains.

The oldest rocks consist of an assemblage of metamorphics of igneous effusive and sedimentary origin, probably, for the most part, of Triassic age. They are intruded by diorite and various hypabyssal rocks, then in turn by granitic rocks, which occupy over 40 percent of the area. Following this last igneous activity of probable Lower Cretaceous age, an extended period of sedimentation started with the deposition of the marine Upper Cretaceous Chico formation and continued during the Paloecene under alternating marine and continental conditions on the margins of the blocks. A marine regression towards the north, during the Neocene, accounts for the younger Tertiary strata in the region under consideration.

Outpouring of basalts to the southeast indicates that igneous activity was resumed toward the close of the Tertiary. The fault zone, which characterizes the Elsinor trough, marks one of the major tectonic lines of southem California. It separates the upthrown and tilted block of the Santa Ana Mountains to the south from the Perris Block to the north.

Most of the faults are normal in type and nearly parallel to the general trend of the trough, or intersect each other at an acute angle. Vertical displacements generally exceed the horizontal ones and several periods of activity are recognized.

Tilting of Tertiary and older Quaternary sediments in the trough have produced broad synclinal structures which have been modified by subsequent faulting.

Five old surfaces of erosion are exposed on the highlands.

The mineral resources of the region are mainly high-grade clay deposits and mineral waters.

The fine-scale seismic structure of the central Mexico, southern Peru, and southwest Japan subduction zones is studied using intraslab earthquakes recorded by temporary and permanent regional seismic arrays. The morphology of the transition from flat to normal subduction is explored in central Mexico and southern Peru, while in southwest Japan the spatial coincidence of a thin ultra-slow velocity layer (USL) atop the flat slab with locations of slow slip events (SSEs) is explored. This USL is also observed in central Mexico and southern Peru, where its lateral extent is used as one constraint on the nature of the flat-to-normal transitions.

In western central Mexico, I find an edge to this USL which is coincident with the western boundary of the projected Orozco Fracture Zone (OFZ) region. Forward modeling of the 2D structure of the subducted Cocos plate using a finite-difference algorithm provides constraints on the velocity and geometry of the slab’s seismic structure in this region and confirms the location of the USL edge. I propose that the Cocos slab is currently fragmenting into a North Cocos plate and a South Cocos plate along the projection of the OFZ, by a process analogous to that which occurred when the Rivera plate separated from the proto-Cocos plate 10 Ma.

In eastern central Mexico, observations of a sharp transition in slab dip near the abrupt end of the Trans Mexican Volcanic Belt (TMVB) suggest a possible slab tear located within the subducted South Cocos plate. The eastern lateral extent of the USL is found to be coincident with these features and with the western boundary of a zone of decreased seismicity, indicating a change in structure which I interpret as evidence of a possible tear. Analysis of intraslab seismicity patterns and focal mechanism orientations and faulting types provides further support for a possible tear in the South Cocos slab. This potential tear, together with the tear along the projection of the OFZ to the northwest, indicates a slab rollback mechanism in which separate slab segments move independently, allowing for mantle flow between the segments.

In southern Peru, observations of a gradual increase in slab dip coupled with a lack of any gaps or vertical offsets in the intraslab seismicity suggest a smooth contortion of the slab. Concentrations of focal mechanisms at orientations which are indicative of slab bending are also observed along the change in slab geometry. The lateral extent of the USL atop the horizontal Nazca slab is found to be coincident with the margin of the projected linear continuation of the subducting Nazca Ridge, implying a causal relationship, but not a slab tear. Waveform modeling of the 2D structure in southern Peru provides constraints on the velocity and geometry of the slab’s seismic structure and confirms the absence of any tears in the slab.

In southwest Japan, I estimate the location of a possible USL along the Philippine Sea slab surface and find this region of low velocity to be coincident with locations of SSEs that have occurred in this region. I interpret the source of the possible USL in this region as fluids dehydrated from the subducting plate, forming a high pore-fluid pressure layer, which would be expected to decrease the coupling on the plate interface and promote SSEs.

Esta dissertação é um estudo comparativo do legado vitoriano deixado para as escritoras do século XX, Virginia Woolf e Sylvia Plath. Primeiro discutem-se as agências controladoras do corpo feminino na era vitoriana e a formação de um ideal de feminilidade que chamamos de Anjo do Lar. Em seguida, discute-se como Virginia Woolf apreende essa imagem e a subverte, criando seu duplo, que chamamos de Demônio do Lar. Por fim, promovemos o diálogo entre Sylvia Plath e Virginia Woolf. Plath parece escrever aos moldes de Woolf, criando uma literatura de morte, feita para assassinar o Anjo do Lar. Usamos para tal estudo o conceito de écriture féminine, criado pelas francófonas Hélène Cixous, Luce Irigaray, e Julia Kristeva, entre outras, para traçar os paralelos entre um lugar para o feminino na escrita e a busca de uma tradição por Woolf. A abjeção de Kristeva, a dinâmica de poder entre alma e corpo de Foucault e o conceito de duplo de Otto Rank nos ajudarão, por fim, a entender como se dá a morte do Anjo na literatura, especificamente no romance A redoma de vidro (1963) de Sylvia Plath

El presente trabajo se centra en un análisis comparativo en varios niveles de las traducciones producidas a partir de la obra teatral Who’s Afraid of Virginia Woolf? (Albee 1962): las de Marcelo De Ridder, José Méndez y Alberto Mira, realizadas con distintos fines y en momentos histórico culturales diferenciados. Asimismo hemos integrado en la comparación la adaptación cinematográfica y los correspondientes textos audiovisuales en inglés y en español, con el fin de ofrecer una visión más inclusiva del modo en que se ha generado esta cadena textual. Para manejar el mencionado corpus, nos hemos valido de herramientas informáticas. Por un lado, el programa TRACEAligner ha resultado de gran utilidad para alinear los textos teatrales. Por otro lado, SubRip ha posibilitado la extracción del subtitulado en inglés y en español del DVD, que después hemos organizado en una tabla bitextual. A través de una metodología fundamentada en estudios de investigación relevantes, hemos examinado el corpus desde una perspectiva extratextual, macroestructural, microestructural e intersistémica. Esto nos ha permitido interrelacionar las traducciones en aspectos tan importantes como los factores contextuales que afectan a su producción, las características de las publicaciones (o del libreto inédito), la transferencia de las unidades estructurales y argumentales, la correspondencia con rasgos de distintos tipos de traducciones, los fenómenos de traducción con mayor incidencia o las adaptaciones derivadas de los procesos de censura. Gracias a la comparación de estos temas, se pueden apreciar las características distintivas de cada texto. Otro asunto que se trata a lo largo del análisis es la identificación del texto fuente de cada traducción, especialmente de la de Méndez. Hemos tratado de demostrar que Méndez parte del texto norteamericano, no de la traducción de Ridder, como se ha sugerido (Espejo 1998: 111 112). Por último, recogemos una serie de conclusiones que pretenden verter luz sobre las cuestiones planteadas en la introducción.

Em seu ensaio de 1924, Mr Bennet and Mrs. Brown, Virginia Woolf declara que por volta de 1910 o caráter humano mudara. A presente tese, seguindo o apontamento da ensaísta Woolf, pretende entender as mudanças promovidas nas duas primeiras décadas do século XX, na Inglaterra, a partir da vida dos artistas e amigos que ficariam eternizados como o Bloomsbury Group. Em nossa primeira parte, apontaremos em que sentido, ao adotar o método pós-impressionista, o Bloomsbury Group alarga as discussões da teoria do conhecimento que fervilhava em Cambridge. Análogo ao silêncio dos quadros, agora totalmente formalistas, apontaremos que a linguagem de resistência de Bloomsbury parece ter sido antecipada pela vida de duas de suas artistas: elas são a própria Virginia Woolf e sua irmã, Vanessa Bell. A partir dessa suposição, de que haja uma conexão entre a vida das mulheres de Bloomsbury e a natureza refratária do grupo, começaremos uma discussão, já em nossa segunda parte, de como o silêncio que marca o feminino construído historicamente ganha um status de uma nova linguagem na prosa de Virginia Woolf. Nesse momento, tal silêncio da prosa parece comparável à própria linguagem poética, e aqui Virginia Woolf dialoga com o futuro, representado por Jean-Paul Sartre. Após marcarmos o que seria a prosa poética, ou poesia prosaica, de Woolf, apontaremos por fim a relação entre essa escrita do silêncio e o conceito de mente andrógina em Virginia Woolf, relação esta mediada pelo movimento que seria chamado de écriture féminine, representado pela francófona Hélène Cixous, entre outras

Using a bioenergetics model, we estimated daily ration and seasonal prey consumption rates for six age classes of juvenile sandbar sharks (Carcharhinus plumbeus) in the lower Chesapeake Bay summer nursery area. The model, incorporating habitat and species-specific data on growth rates, metabolic rate, diet composition, water temperature (range 16.8−27.9°C), and population structure, predicted mean daily rations between 2.17 ±0.03 (age-0) and 1.30 ±0.02 (age-5) % body mass/day. These daily rations are higher than earlier predictions for sandbar sharks but are comparable to those for ecologically similar shark species. The total nursery population of sandbar sharks was predicted to consume ~124,000 kg of prey during their 4.5 month stay in the Chesapeake Bay nursery. The predicted consumption rates support the conclusion that juvenile sandbar sharks exert a lesser top-down effect on the Chesapeake Bay ecosystem than do teleost piscivores and hu

The Central Marine Fisheries Research Institute (CMFRI) in India developed bivalve farming technologies in the 1970s, but these were not widely adopted at the time. In 1993, CMFRI undertook an action research program to encourage farming of edible oysters (Crassostrea madrasensis), mussels (Perna viridis and Perna indica), clams (Paphia malabarica) and pearls (Pinctada fucata) along the southwest coast of India. Successful demonstration of the viability of bivalve farming led to the initiation of commercial farming of mussels and generated interest among farmers and entrepreneurs in developing production of pearls and farming of edible oysters. Given the high potential for the mollusc aquaculture, both for the local and export market, issues such as demarcation and issuance of lease right on aquaculture zones in public waterbodies by the government, organization of marketing systems and provisions for technical and financial support to farmers need to be addressed.
