New Mediterranean Biodiversity Records (December 2017)

The “New Mediterranean Biodiversity Records” series includes new records of marine species found in the Mediterranean basin and/or information on the spatial distribution of already established species of particular interest. The current article presents information on 20 marine taxa classified per country according to their geographic position in the Mediterranean, from west to east. The new records per ecoregion are as follows: Algeria: the first record of the fish Etrumeus golanii is reported along the Algerian coast. Tunisia: the alien jellyfish Phyllorhiza punctata is reported for the first time in the Gulf of Gabès. Italy: the first record of Siganus rivulatus in the Strait of Sicily and a new record of Katsuwonus pelamis from the central Tyrrhenian Sea are reported. The establishment of the isopod of the genus Mesanthura in the northern Tyrrhenian with some notes on its ecology are also included. Croatia: signs of establishment of the Lessepsian Siganus luridus and the occurrence of the alien mollusc Rapana venosa are reported. Albania: the first record of the elasmobranch Alopias superciliosus and a recent sighting of the rare monk seal Monachus monachus in Albanian waters are given. Greece: signs of the establishment of the fish Parupeneus forsskali and of the ascidian Hermania momus in Hellenic Aegean waters are reported. Turkey: a new record of the fish P. forsskali and of the Acarea of the genus Acaromantis and Simognathus are given, while the first case of Remora australis in association with delphinids and the occurrence of the sea star Coscinasterias tenuispina are reported. Also, the establishment of the two alien species Isognomon legumen and Viriola sp. [cf. corrugata] are presented. Egypt: the fish Bathygobius cyclopterus is reported for the first time in Mediterranean Sea waters. Also, a new record of Pagellus bogaraveo and a first record of Seriola fasciata in Egyptian Mediterranean waters are reported. Lebanon: the first record of Dondice banyulensis is presented

Transient up- and down-regulation of expression of myosin light chain 2 and myostatin mRNA mark the changes from stratified hyperplasia to muscle fiber hypertrophy in larvae of gilthead sea bream (Sparus aurata L.)

Hyperplasia and hypertrophy are the two mechanisms by which muscle develops and grows. We study these two mechanisms, during the early development of white muscle in Sparus aurata, by means of histology and the expression of structural and regulatory genes. A clear stage of stratified hyperplasia was identified early in the development of gilthead sea bream but ceased by 35 dph when hypertrophy took over. Mosaic recruitment of new white fibers began as soon as 60 dph. The genes mlc2a and mlc2b were expressed at various levels during the main phases of hyperplasia and hypertrophy. The genes myog and mlc2a were significantly up-regulated during the intensive stratified formation of new fibers and their expression was significantly correlated. Expression of mstn1 and igf1 increased at 35 dph, appeared to regulate the hyperplasia-to-hypertrophy transition, and may have stimulated the expression of mlc2a, mlc2b and col1a1 at the onset of mosaic hyperplasia. The up-regulation of mstn1 at transitional phases in muscle development indicates a dual regulatory role of myostatin in fish larval muscle growth

A manifestação da afetividade em sujeitos jovens e adultos com deficiência mental: perspectivas de Wallon e Bakhtin The affective level of young people with intellectual disability and adults: Wallon's and Bakhtin's perspectives

No presente texto discute-se a objetivação das emoções na trama discursiva desenvolvida por jovens e adultos com deficiência mental participantes de um programa de atendimento pedagógico alternativo. Como recurso metodológico utiliza-se na construção dos dados a análise microgenética de episódios de curta duração, episódios recortados da dinâmica interativa da qual participavam os sujeitos. Os resultados obtidos evidenciam formas diferenciadas de inter-relações se concretizando, a exteriorização das emoções sendo mediada por linguagens simbólicas, tais como aparecem referenciadas em Wallon (como função adaptativa e comunicativa) e em Bakhtin (como função mediadora e ato de significação), autores fundamentados na matriz epistemológica do materialismo histórico dialético.<br>The purpose of emotions within discourse developed by young people with intellectual disabilities and adults who participate in an alternative pedagogical program for people with special needs is discussed. Micro-genetic analyses of short duration episodes are employed in data construction as a methodological resource. Episodes are cross-sections of interactive dynamics in which the subjects participate. Results show a variety of inter-relationships being established, as well as the overt manifestation of affect mediated by symbolic language, as referred to by authors based on the historical and dialectical materialism epistemology, such as Wallon (as an adaptive and communicative function) and by Bakhtin (as a mediating function and significant action)

A construção da identidade de sujeitos deficientes no grupo terapêutico-fonoaudiológico Identity formation of disabled individuals within a speech therapy group

Neste estudo, consideramos que o sujeito se constitui à medida que suas ações vão sendo interpretadas pelo outro, através da internalização de papéis, definidos, inicialmente, pelas pessoas que são referência mais concreta da criança, como a família e, posteriormente, pelo grupo social maior do qual ela faz parte. Nosso objetivo foi refletir sobre a formação/construção da identidade de jovens deficientes mentais que participavam de atendimento fonoaudiológico, realizado em grupo, analisando o papel da linguagem no processo de construção da imagem que o sujeito faz de si mesmo. O estudo teve sua origem a partir dos resultados obtidos em pesquisas realizadas anteriormente, com grupos de irmãos de sujeitos considerados deficientes mentais. Esses resultados revelaram a imagem negativa que os irmãos têm em relação ao irmão deficiente. O material analisado faz parte de um banco de dados de dois anos de filmagens das interações de jovens deficientes no grupo terapêutico-fonoaudiológico de uma clínica-escola. Os dados foram transcritos e analisados segundo diretrizes da análise microgenética considerando as minúcias dos acontecimentos, os detalhes e o recorte de episódios interativos, sendo o exame orientado para o funcionamento dos sujeitos, as relações intersubjetivas e as condições sociais da situação. As análises realizadas procuraram relacionar a imagem que esses sujeitos têm de si com a imagem transmitida pelo grupo social do qual eles fazem parte. Os resultados mostraram a ressonância do discurso do grupo social nos dizeres dos sujeitos. Concluímos que para transformar a imagem que os sujeitos deficientes mentais têm de si mesmos, precisamos ações que incidam sobre aqueles que os rodeiam, ou seja, a família, os amigos, os colegas e o grupo social em geral.<br>In this study, we consider the personality of our subjects as being shaped by means of their actions being interpreted by others. This happens via the internalization of roles. These roles are defined, in the first instance, by those persons who provide the most concrete reference points for the child, in particular their family, and beyond that by the wider social group to which they belong. Our objective was to reflect upon the formation of the personal identity of mentally disabled young people who were receiving speech therapy, this therapy being conducted in a group context. Transcripts of the language used by the subjects in constructing their self image were analyzed. This study was based upon the results obtained from previous research, conducted with groups of siblings of subjects classified as mentally disabled. These results revealed a negative image held by those siblings of their disabled brother or sister. The material analyzed is part of a data bank of videotapes, of disabled youngsters receiving group speech therapy in a school clinic setting, taken over a two year period. This data was transcribed and analyzed according to the guidelines of micro genetic analysis, taking into consideration minute details of interviews and in particular details and clips of interactive episodes. The examination of the data was directed towards the actions of the subjects of the study, their interpersonal relations and the social context in which these took place. The analysis conducted in this study aims to establish a relationship between the images these subjects have of themselves and the image put across by the social group to which they belong. The results demonstrated the resonance of the discourse of the social group in the verbalizations of the subjects. We conclude that to transform the image that the subjects with intellectual disability have of themselves it is necessary to direct actions to those who are close to them, namely family, friends, colleagues and their social group in general
