Estimates of body sizes at maturation and at sex change, and the spawning seasonality and sex ratio of the endemic Hawaiian grouper (Hyporthodus quernus, F. Epinephelidae)

A case study of the reproductive biology of the endemic Hawaiian grouper or hapu’upu’u (Hyporthodus quernus) is presented as a model for comprehensive future studies of economically important epinephelid groupers. Specimens were collected throughout multiple years (1978–81, 1992–93, and 2005–08) from most reefs and banks of the Northwestern Hawaiian Islands. The absence of small males, presence of atretic oocytes and brown bodies in testes of mature males, and both developed ovarian and testicular tissues in the gonads of five transitional fish provided evidence of protogynous hermaphroditism. No small mature males were collected, indicating that Hawaiian grouper are monandrous (all males are sex-changed females). Complementary microscopic criteria also were used to assign reproductive stage and estimate median body sizes (L50) at female sexual maturity and at adult sex change from female to male. The L50 at maturation and at sex change was 580 ±8 (95% confidence interval [CI]) mm total length (TL) and 895 ±20 mm TL, respectively. The adult sex ratio was strongly female biased (6:1). Spawning seasonality was described by using gonadosomatic indices. Females began ripening in the fall and remained ripe through April. A February–June main spawning period that followed peak ripening was deduced from the proportion of females whose ovaries contained hydrated oocytes, postovulatory follicles, or both. Testes weights were not affected by season; average testes weight was only about 0.2% of body weight—an order of magnitude smaller than that for ovaries that peaked at 1–3% of body weight. The species’ reproductive life history is discussed in relation to its management.

Species of the rougheye rockfish complex: resurrection of Sebastes melanostictus (Matsubara, 1934) and a redescription of Sebastes aleutianus (Jordan and Evermann, 1898)(Teleostei: Scorpaeniformes)

The widespread and commercially important rougheye rockfish, Sebastes aleutianus (Jordan and Evermann, 1898), has been considered a single variable species, with light- and dark-colored forms, found on the outer continental shelf and upper slope of the North Pacific Ocean. Genetic analysis of 124 specimens verified the presence of two species in new specimens collected from Alaska to Oregon, and the two species were analyzed for distinguishing color patterns and morphological characters. Characters distinguishing the two were extended to an analysis of 215 additional formalin-fixed specimens representing their geographic ranges. Sebastes aleutianus is pale, often has dark mottling on the dorsum in diffuse bands, and does not have distinct dark spots on the spinous dorsal fin; it ranges from the eastern Aleutian Islands and southeastern Bering Sea to California. Sebastes melanostictus (Matsubara, 1934), the blackspotted rockfish, ranges from central Japan, through the Aleutian Islands and Bering Sea, to southern California. It is darker overall and spotting is nearly always present on the spinous dorsal fin. Sebastes swifti (Evermann and Goldsborough, 1907) is a synonym of S. aleutianus; S. kawaradae (Matsubara, 1934) is a synonym of S. melanostictus. The subgenus Zalopyr is restricted to S. aleutianus and S. melanostictus. Nomenclatural synonymies, diagnoses, descriptions, and distributions are provided for each species.

Exploitation and reproduction of the spotted eagle ray (Aetobatus narinari) in the Los Frailes Archipelago, Venezuela

We studied a small artisanal fishery for the spotted eagle ray (Aetobatus narinari) off Margarita Island in northeastern Venezuela. We analyzed data from 413 fishing trips directed at A. narinari over a 29-month sampling period (August 2005–December 2007). These trips yielded 55.9 metric tons and 1352 individuals from which a subsample of 846 females and 321 males was used for biological data. Maximum fishing effort and landings occurred between February and May, and catch per unit of effort was highest between December and February and between July and October with an overall average of 3 individuals and 133 kg per trip. The overall sex ratio was significantly different from 1:1 with a predominance of females. Females ranged in size with disc widths (DW) from 64 to 226 cm. Males ranged in size between 97 and 190 cm DW. There was no statistically significant difference between male and female length-weight relationships. Mean fecundity was estimated at 3.09 embryos per female, and the largest embryo measured 44.5 cm DW. Females in different maturity stages were found in all months, except November 2007, the month when all females were immature. Postgravid females occurred mainly during the periods of January–May and July–October. Mean length (L50) at maturity was estimated at 129.2 cm DW for males and 134.9 cm DW for females. This study provides much needed information on the biology and life history of A. narinari for the management of an intensive, directed, small-scale fishery for this little known species in northeastern Venezuela.

Memes pluralistas práticas linguístico-midiáticas em fenômenos bilíngues: um estudo sistêmico-funcional e multimodal sobre propagação via corpora digitais

Investigou-se pelo presente estudo se a concepção presente na Teoria de Replicadores, expressa através do conceito de meme (DAWKINS, 1979), poderia ser um modelo compatível para explicar a propagação de memes no substrato das mídias sociais. No âmbito dos estudos locais, Recuero (2006) sugeriu uma transdução desse modelo, baseando-se nas concepções de Dawkins (1979). Refletindo sobre o posicionamento epistemológico de Recuero (2006), o presente trabalho, baseando-se em Dennett (1995), Blackmore (2002) e Tyler (2011b; 2013b), procedeu às instâncias de Análise Conceitual e Composicional dessa transdução. A partir do conceito de memeplexo (BLACKMORE, 2002), esta pesquisa de base linguística (HALLIDAY, 1987) entende os memes, no substrato das mídias digitais/sociais, como práticas de produção e distribuição linguístico-midiáticas, propaladas a partir de diversas unidades de propagação e das relações criadas pelos internautas nesse processo de transmissão. Investigando tais relações, a partir da instância de Análise Relacional, propõe-se examinar duas unidades de propagação. Expressões meméticas (Que deselegante e #Tenso) e imagens meméticas (oriundas do fenômeno memético Nana em desastres). Integram este estudo dois corpora de expressões meméticas (5275 postagens oriundas ou redirecionadas para o Twitter.com total de 83.655 palavras/tokens) e um corpus bilíngue (Português/Inglês) de imagens meméticas (um total de 134 imagens oriundas do Tumblr.com e Facebook.com). Para analisar os corpora de expressões meméticas utilizou-se a metodologia de Linguística de Corpus (BERBER-SARDINHA, 2004; SHEPHERD, 2009; SOUZA JÚNIOR, 2012, 2013b, 2013c). Para a análise do corpus multimodal de imagens meméticas, utilizou-se a metodologia que chamamos de Análise Propagatória. Objetivamos verificar se essas unidades de propagação e as práticas linguístico-midiáticas que estas transmitem, evoluiriam somente devido a aspectos memético-midiáticos, conforme Recuero (2006) apontara, e com padrão de propagação internalista (DAWKINS, 1979; 1982). Após análise dos dados, revelou-se que, ao nível do propósito, os fenômenos locais investigados não evoluíram por padrão internalista (ou homogêneo) de propagação. Tais padrões revelam ser de natureza externalista (ou heterogênea). Ademais, constatou-se que princípios constitutivos meméticos de evolução como os de fecundidade, longevidade (DAWKINS 1979; 1982) e o de design (DENNETT, 1995), junto com o princípio midiático de evolução de alcance (RECUERO, 2006) mantiveram-se presentes com alto grau de influencia nas propagações de natureza externalista. Por outro lado, o princípio memético da fidelidade (DAWKINS, 1979; 1982) foi o que menos influenciou esses padrões de propagação. Neutralizando a fidelidade, e impulsionados pelo princípio de design, destacaram-se nesse processo evolutivo os princípios linguísticos sistematizadores revelados por este estudo. Isto é: o princípio da funcionalidade (memes evoluem porque podem indicar propósitos diferentes) e o princípio do alcance linguístico (memes podem ser direcionados a itens animados/ inanimados; para internautas em idioma nativo/ estrangeiro)
