A survey of river habitats on the River Lune

A survey of the River Lune using River Habitat Survey (RHS) was carried out at 103 sections in February/March 99, to which were added 37 sites surveyed between 1994 -1996. Summary statistics were produced on the distribution and extent of flow features (e.g. riffles, pools, rapids etc.), substrate types, tree and associated features and bank profiles. Information on land-use and management was also included in the analyses. A Habitat Modification Score (HMS) describing the level of habitat modification was derived for each site and compared to the whole reference network and to rivers of similar types in Britain. The HMS shows that more than 70% of the sites on the catchment are predominantly unmodified and very few sites are significantly modified. Highly modified sites are concentrated in the urban areas and on the tributaries.

Spatial and seasonal abundance of sand seatrout (Cynoscion arenarius) and silver seatrout (C. nothus) off the coast of Texas, determined with twenty years of data (1987–200

Sand seatrout (Cynoscion arenarius) and silver seatrout (C. nothus) are both found within the immediate offshore areas of the Gulf of Mexico, especially around Texas; however information is limited on how much distributional overlap really occurs between these species. In order to investigate spatial and seasonal differences between species, we analyzed twenty years of bay and offshore trawl data collected by biologists of the Coastal Fisheries Division, Texas Parks and Wildlife Department. Sand seatrout and silver seatrout were distributed differently among offshore sampling areas, and salinity and water depth appeared to correlate with their distribution. Additionally, within the northernmost sampling area of the gulf waters, water depth correlated significantly with the presence of silver seatrout, which were found at deeper depths than sand seatrout. There was also an overall significant decrease in silver seatrout abundance during the summer season, when temperatures were at their highest, and this decrease may have indicated a migration farther offshore. Sand seatrout abundance had an inverse relationship with salinity and water depth offshore. In addition, sand seatrout abundance was highest in bays with direct passes to the gulf and correlated with corresponding abundance in offshore areas. These data highlight the seasonal and spatial differences in abundance between sand and silver seatrout and relate these differences to the hydrological and geological features found along the Texas coastline.

Deuses que dançam e conclamam a revolução: a construção da identidade de resistência em A ilha sob o mar, de Isabel Allende

Este trabalho tem como objetivo identificar os processos através dos quais a personagem Zarité, protagonista do romance A ilha sob o mar (ALLENDE, 2010), constrói sua identidade de resistência (CASTELLS, 2013). Sujeito subalterno por ser simultaneamente escrava, negra e mulher (SPIVAK, 2010), ela desenvolve estratégias verossímeis que lhe permitem sobreviver e enfrentar a opressão física e identitária típica de sua condição na colônia francesa de São Domingos, atual Haiti, que vivia, à época, sob o domínio de um modelo político e social profundamente patriarcal, escravocrata e racista. A pesquisa assume a perspectiva desenvolvida em torno da literatura de autoria feminina na América Latina (CUNHA, 2004; RAGO, 2004; VELASCO-MARÍN, 2007; WARD, 2007), segundo a qual, nessa produção específica, desenvolvem-se representações de mulher às quais são garantidas a voz e o empoderamento que lhes foram negados em outros contextos de escrita literária. Alinhando a noção de estranhamento desenvolvida pelo formalismo russo (CHKLOVSKI, 2013) com a do uso de procedimentos capazes de conferir literariedade à narrativa (LUKÁCS, 1968), este trabalho verifica a configuração de condições que conferem à obra o pertencimento ao contexto das produções desenvolvidas por autoras migrantes ou exiladas (SKAR, 2001). O conceito de hibridismo (CANCLINI, 2011) se soma a esse entendimento, articulando-se, nesta pesquisa, com a perspectiva multicultural de compreensão das identidades (HALL, 2005). Hutcheon (1991) fornece o arcabouço que nos permite o necessário trabalho com o conceito de sujeito marginalizado e ex-cêntrico. Para isso, é utilizado também o embasamento teórico oferecido por Castells (2013) no tocante ao desenvolvimento da noção de identidade de resistência. As condições históricas e econômicas sob as quais se desenvolveu o regime vigente no ambiente em que se passa a narrativa são verificadas em James (2010) e Blackburn (2003). Para lidar com a vivência religiosa e cultural experimentada pelos descendentes de africanos naquele contexto, a pesquisa se embasa nos argumentos trazidos por Capone (2011) ao debate acerca desse tema e, por intermédio dos estudos de Garauday (1980) e Lody & Sabino (2011), é possível angariar informações relativas à história e à simbologia envolvidas nas danças de origem africana. O estudo dessas correntes teóricas conduz à conclusão de que o romance A ilha sob o mar encena, na personagem Zarité, a construção de uma identidade de resistência entre os escravos que, dançando, celebravam seus deuses, permitiam o encontro das diferentes culturas das quais eram originários e fortaleciam a rede de relações, informações e colaboração mútua entre os indivíduos e as comunidades que pretendiam livrar-se do domínio do elemento europeu e de seu regime escravocrata

The dusky rockfishes (Teleostei: Socrpaeniformes) of the North Pacific Ocean: resurrection of Sebastes variabilis (Pallas, 1814) and a redescription of Sebastes ciliatus (Tilesius, 1813)

The dusky rockfish (Sebastes ciliatus) of the North Pacific Ocean has been considered a single variable species with light and dark forms distributed in deep and shallow water, respectively. These forms have been subjected to two distinct fisheries separately managed by federal and state agencies: the light deep form is captured in the offshore trawl fishery; the dark shallow form, in the nearshore jig fishery. The forms have been commonly recognized as the light dusky and dark dusky rockfishes. From morphological evidence correlated with color differences in some 400 specimens, we recognize two species corresponding with these color forms. Sebastes ciliatus (Tilesius) is the dark shallow-water species found in depths of 5−160 m in the western Aleutian Islands and eastern Bering Sea to British Columbia. The name Sebastes variabilis (Pallas) is resurrected from the synonymy of S. ciliatus to apply to the deeper water species known from depths of 12−675 m and ranging from Hokkaido, Japan, through the Aleutian Islands and eastern Bering Sea, to Oregon. Sebastes ciliatus is uniformly dark blue to black, gradually lightening on the ventrum, with a jet black peritoneum, a smaller symphyseal knob, and fewer lateral-line pores compared to S. variabilis. Sebastes variabilis is more variable in body color, ranging from light yellow to a more usual tan or greenish brown to a nearly uniform dark dorsum, but it invariably has a distinct red to white ventrum. Synonymies, diagnoses, descriptions, and geographic distributions are provided for each species.
