As competições sociais em grupos de Callithrix jacchus (Callitrichidae, Primates) são influenciadas pelo parentesco e pela convivência?

The Callitrichidae family is characterized by flexibility in its mating system, being possible to find monogamous, polyandrid and polygynic groups. Its social organization and mating system can be defined by the interaction between ecological and demographic factors plus the degree of relatedness among the individuals in the population. The objective of this work was to demonstrate the influence of relatedness and coexistence on the establishment and maintenance of social relations between Callithrix jacchus adult males. Four pairs of related adult males (CP), 4 pairs with coexistence between the animals in the pair (CC) and 4 pairs with no relatedness (SP) were studied. The pairs in the group CC had been kept in the same cage for at least 8 months before the experiment and the pairs in the group SP were put together at the beginning of the study. Each animal was observed 3 times/week for 2 months, in 15 min. sessions, through focal time sampling with instantaneous record each minute. In the first month, only the pair of males was kept in the cage (Phase I) and in the second month, a female was introduced into the cage (Phase II). The affiliative, agonistic and sexual interactions were registered. Affiliative interactions showed similar frequencies for all groups in phases. There was also no significant difference in the agonistic interactions of the CP, CC and SP males in Pase I, even considering that group SP exhibited higher levels of agonism. In Phase II, there was a statistically significant increase comparing to the others. The results demonstrate that relatedness and coexistence are of great importance for maintaining reprodutive and social stability inside the group. Nonetheless, in this study, only one of the males in the pair had sexual interations with the females, except for 2 pairs. This was assured through mate guarding and agonism directed to the potencial competitor. The most probable mating system would be functional monogamy, where the males would present low levels of competition, if there is relatedness and coexistence among them; on the other hand, a strong competition if there is no relatedness between the individuals. Even so, a polyandric system would also have to be considered

Uma reflexão sobre a elaboração de um léxico bilíngüe preliminar na subárea de cardiologia a partir do uso de termos encontrados em um corpus paralelo e em dois corpora comparáveis

O objetivo principal deste trabalho foi propor uma reflexão sobre o processo a ser utilizado para a elaboração de um léxico bilíngüe na subárea de cardiologia. Para tanto, tomamos como base os conceitos dos estudos da tradução baseados em corpus, da lingüística de corpus e da terminologia. Como material para compor os corpora utilizamos artigos de cardiologia escritos em português e traduzidos para o inglês, assim como artigos originalmente escritos em português e em inglês. Com base no léxico proposto, pudemos notar algumas diferenças e algumas correspondências de uso entre os termos que aparecem no subcorpus de estudo de textos originais e traduzidos e nos corpora comparáveis em português e em inglês. Essa diferença apontaria que os termos não seriam unívocos dentro dessa linguagem de especialidade devido às diferenças de uso pelos especialistas de cardiologia para designar um mesmo referente.

Termos botânicos

Há termos botânicos que são heterofônicos. O significado e a perfeita prosadia doles obém-se em linguagem científica, através da etimologia. Como exemplo,encontram-se mesofilo e mesófilo. Este, sendo proparoxítono, refere-se aquilo que vive em lugares de luz difusa e umidade média; e aquale, referindo-se a anatomia da folha, é paroxítono. Com relação ao termo taxinomia, formado pelos prefixos gregos taxi e namo e mais o sufixo -ia, não deixa de ser a melhor combinação e deve-se, portanto, rejeitar as formas paralelas de taxeonomia, taxionomia e taxonomia.

Movimentos religiosos totalitários católicos: efeitos em termos de produção de subjetividade

Nossa pesquisa visa estudar a produção de subjetividade em instituições e estabelecimentos católicos dedicados à formação religiosa de seus membros. Neste artigo, tomamos como estudo o caso de um relato feito por um ex-membro do movimento Focolare. Procuramos descrever seu percurso formativo, sua integração e posterior abandono do grupo religioso. Operando basicamente por subtração e por meio de acréscimo de imaginário, a tecnologia empregada pelos movimentos religiosos integristas pode produzir uma subjetividade serializada de matiz fortemente fanático, sem espaço para a individualidade, para a iniciativa criadora, para a singularidade. Concluímos com algumas notas psicossociais relativas à compreensão psicanalítica do fanatismo religioso.

Avaliação das Farinhas de Peixe e Pena, no Confinamento de Bezerros Leiteiros Desmamados, Através de Dietas Calculadas em Termos de Proteína Bruta ou de Proteína Metabolizável

The objectives of this work were to evaluate three protein sources - soybean meal, fish meal and feather meal - and two methods of calculation of rations - the calculated in terms of crude protein (CP), according to recommendations of NRC (1988); and the proposed by the AFRC (1993), and calculated in terms of metabolizable protein (MP) - through the performance of calves. The animals were confined and submitted to five diets, that varied only protein sources in its composition, thus discriminated: SM- Soybean Meal, FsM- Fish Meal, FeM- Feather Meal, FsMU- Fish Meal and Urea, and FeMU Feather Meal and Urea. A complete diet was supplied, composed of 40% of sorghum silage and 60% of concentrate. All treatments possessed about of 2.56 Mcal/kg DM of metabolizable energy, being the treatments SM, FsM and FeM calculated by the system of CP, with 18% of CP, and the treatments FsMU and FeMU, calculated by the system of MP, with 16.3% of CP and a same amount of metabolizable protein than the treatment SM, with 112.0 grams of MP/day. Individually, the treatments did not present significant differences (P > 0.05) in the final alive weight, in daily gain weight and in dry matter intake, having differences only in the feed:gain ratio. The best feed:gain ratio happened in the treatment FsM and the worst in the treatment FeMU. It is concluded that the MP method provides similar results to the method of CP. The treatments with fish meal provide larger weight gains, smaller intake and better feed:gain ratio than the treatments with feather meal, staying the treatment soybean meal with intermediary daily gain.

Sistema de reprodução, parentesco e tamanho efetivo em sementes de polinização livre de populações fragmentadas de Copaifera langsdorffii Desf. por análise de locos microssatélites

Anthropogenic changes in the reproductive population density can affect the mating system and result in an increase in selfing and correlated matings. This study investigated the mating system in small fragmented populations of the insect pollinated tropical tree species Copaifera langsdorffii, using microsatellite loci and the mixed and correlated mating models. Open-pollinated seeds were collected from 15 seed-trees located in a small forest fragment (4.8 ha), denominated Bosque and from 14 other seed-trees located in other small forest fragments of the north-western region of São Paulo State. No significant differences were observed between the seed-trees from Bosque (tm=0.933±0.028) and other fragments (tm=0.971±0.032), although these estimates were significantly different from 1.0, suggesting that selfing was occurring. Differences between multilocus and unilocus outcrossing rate were significantly high in both seed-trees of Bosque (tm -ts=0.478±0.05) and other forest fragments (tm -ts=0.475±0.018), suggesting a spatial genetic structure in those stands. The results also showed high rates of correlated mating in the samples, indicating that a good part of the offspring were full-sibs. As a consequence of selfing, mating among relatives and correlated matings, the coancestry within families was equally high in the seed-trees of Bosque ((Θ=0.237) and in the seed-trees of the other forest fragments (Θ=0.241) and the effective population size was lower than expected in panmitic populations (Ne<4). The results were discussed, focusing on the sample size of seed-trees to collect seeds for genetic conservation and enviromental reforestation.
