Abstract Globally, there is limited knowledge about management and conservation of Callianassidae family. Their catches seem to be recently increasing in several parts of the world and evidences raise concern on the need of specialized literature focused on populations monitoring. At Southeast of Brazil, the species Callichirus major (Say 1818), known as the ghost shrimp, is frequently captured for use as bait in sport fishing and, according to previous studies, the overexploitation could threaten the population. The aim of this study was evaluated over a year this harmful human pressure on the species C. major in two beaches contiguous but susceptible to different anthropogenic impacts due to the existence of legislation on one beach that prohibits the capture of this crustacean. The population of C. major presented where the prohibition regulation does not exist a density almost three times lower when compared to the beach that prohibits the capture, with individuals with smaller carapace oval area and a shorter reproductive period. This paper alert to some evidence of C. major structure population disturbance resulting from its exploitation at Southeast of Brazil. Recommendations were also addressed to conservation management considering the species' ecological importance.

Resumo: Neste artigo, refletimos acerca de um conjunto de trocas interacionais realizadas nos perfis do Facebook de duas mulheres negras de destaque na mídia televisiva. Concentramos nossos esforços em produzir conhecimento sobre a (re)produção de discursos de injúria racial e de gênero num contexto on-line. Partindo da concepção de linguagem como ação, promovemos um diálogo com perspectivas teóricas relacionadas às questões raciais. Os dados gerados nos permitem inferir que os atos de fala performativos de injúria racial e de gênero apontam para discursos e crenças que ainda constroem as mulheres negras, mesmo as bem-sucedidas, como ‘animalescas’ e ‘inferiores’ e cujos corpos estão ‘naturalmente e sempre à disposição’ de ataques violentos de diversas ordens, inclusive as verbais.

Abstract: The present text aims to reflect on interactional exchanges unfolded on two black women’s Facebook profiles. Both have been on the spotlight on Brazilian television. Our focus is to produce knowledge regarding the discursive (re)production of race and gender-related slurs in an on-line context. Based on the assumption that language is action, we promote a dialogue with theoretical perspectives on ‘race’ and ‘racism’. The data the study generated allow us to infer that the performative speech acts of racial and gender-related slurs point to discourses and beliefs which still construct black women as ‘inferior’ and ‘bestial’ - regardless their statuses - whose bodies are ‘naturally always ready and available’ to different kinds of (including verbal) assaults.

O caranguejo de manguezal Ucides cordatus é um dos crustáceos mais explorados do Brasil. O presente estudo investigou a época reprodutiva desta espécie e o período do fenômeno da “andada”, quando os caranguejos estão ativos fora das tocas e ocorrem comportamentos agonísticos. Além disso, estes fatores foram relacionados com fatores ambientais em um manguezal da costa brasileira, com inferência sobre o manejo deste caranguejo. Os caranguejos reproduziram de outubro a fevereiro. A “andada” ocorreu de novembro a fevereiro, com características típicas nos primeiros dois meses, durante os períodos de lua cheia e lua nova, e foi influenciada positivamente pela temperatura do ar e do solo, luminosidade e amplitude de maré e negativamente pela salinidade. Baseado nos resultados do presente estudo, o período quando a “andada”ocorre poderia ser definido em outras partes do Brasil, o que auxiliaria no manejo deste recurso pesqueiro. Para Iguape, Estado de São Paulo, Brasil, sugerimos a proibição da pesca para ambos os sexos durante o mês de dezembro ou durante as luas cheia e nova, incluindo o mês de janeiro.

The mangrove crab Ucides cordatus is one of the most exploited crustaceans in Brazil. The present study investigated the breeding season of this species and the period of the “andada” phenomenon, when the crabs are active outside their burrows and perform agonistic behaviors. Furthermore related them to environmental factors, in a mangrove on the coast of Brazil, with inferences about management of this crab. The crabs reproduced from October through February. The “andada” occurred from November through February, with typical characteristics in the first two months, during the full and new moon periods, and was influenced positively by the air and soil temperature, luminosity, and tidal amplitude, and negatively by salinity. Based on the results of the present study, the period when the “andada” occurs in other parts of Brazil could be defined, which will aid in managing this fishery. For Iguape, state of São Paulo, Brazil, we suggest a legal off-season for both sexes in December or during the full and new moon, including January.

Apresentamos os resultados de inventários de morcegos realizados em três áreas de floresta urbana (78, 9 e 2 ha) localizadas no município de Juiz de Fora. Entre maio de 2001 e maio de 2002, 209 morcegos foram capturados e marcados, representando sete espécies comuns em habitats urbanos (Artibeus lituratus, Platyrrhinus lineatus, Anoura caudifer, Sturnira lilium, Carollia perspicillata, Myotis nigricans e Molossus molossus). Apenas A. lituratus foi amostrada em todas as áreas, além de ter sido a mais abundante em todas elas, indicando sua alta resistência à fragmentação. Dois indivíduos desta espécie foram recapturados em uma área diferente daquela em que haviam sido marcados anteriormente. Sugerimos que as áreas estudadas apresentam valor significativo para a manutenção de alguns quirópteros, funcionando como "trampolins ecológicos", unindo populações, bem como fragmentos.

We present the results of bats' inventories carried out in three areas of urban forests (78, 9 and 2 ha) located in Juiz de Fora City. Between May 2001 and May 2002, 209 bats were captured and marked, representing seven common species in urban habitats (Artibeus lituratus, Platyrrhinus lineatus, Anoura caudifer, Sturnira lilium, Carollia perspicillata, Myotis nigricans and Molossus molossus). Only A. lituratus occurred in all patches, besides been the most abundant in all of them, indicating its high resistance to fragmentation. Two individuals of this species were recaptured in a different area from the one which they had been marked previously. We suggested that the studied areas have significant value for the maintenance of some bats, performing as "stepping stones", uniting populations, as well as fragments.
