Karyotypic evolution of ribosomal sites in buffalo subspecies and their crossbreed

Domestic buffaloes are divided into two group based on cytogenetic characteristics and habitats: the “river buffaloes” with 2n = 50 and the “swamp buffaloes”, 2n = 48. Nevertheless, their hybrids are viable, fertile and identified by a 2n = 49. In order to have a better characterization of these different cytotypes of buffaloes, and considering that NOR-bearing chromosomes are involved in the rearrangements responsible for the karyotypic differences, we applied silver staining (Ag-NOR) and performed fluorescent in situ hybridization (FISH) experiments using 18S rDNA as probe. Metaphases were obtained through blood lymphocyte culture of 21 individuals, including river, swamp and hybrid cytotypes. Ag-NOR staining revealed active NORs on six chromosome pairs (3p, 4p, 6, 21, 23, 24) in the river buffaloes, whereas the swamp buffaloes presented only five NOR-bearing pairs (4p, 6, 20, 22, 23). The F1 crossbreed had 11 chromosomes with active NORs, indicating expression of both parental chromosomes. FISH analysis confirmed the numerical divergence identified with Ag-NOR. This result is explained by the loss of the NOR located on chromosome 4p in the river buffalo, which is involved in the tandem fusion with chromosome 9 in this subspecies. A comparison with the ancestral cattle karyotype suggests that the NOR found on the 3p of the river buffalo may have originated from a duplication of ribosomal genes, resulting in the formation of new NOR sites in this subspecies.

Anurofauna em uma área na Depressão Periférica, no centro-oeste do estado de São Paulo, Brasil

A anurofauna do estado de São Paulo, nas últimas oito décadas, tem sido foco do estudo de importantes grupos de pesquisa em anfíbios anuros. Porém, pesquisas realizadas com comunidades na área da Depressão Periférica do centro-oeste paulista ainda são escassas. A fim de trazer novas informações sobre essa região, nosso objetivo foi inventariar a anurofauna de uma área na Depressão Periférica, associando os resultados com dados da literatura e confrontando os mesmos com aqueles conhecidos para a anurofauna no altiplano da Cuesta de Botucatu. O inventário foi realizado a partir dos dados obtidos em 24 dias de amostragem, decorridos 13 meses de coleta (dezembro de 2008 a dezembro de 2009). Os anuros foram amostrados em potenciais sítios reprodutivos, pelos métodos de encontro visual e busca auditiva. Foram registradas 29 espécies distribuídas em 12 gêneros e seis famílias. Apesar da maioria das espécies serem predominantemente de áreas abertas, consideramos a riqueza elevada, e associamos essa riqueza à existência dos remanescentes de mata nos interflúvios. Entretanto, apesar da presença desses remanescentes, a ocorrência de espécies associadas exclusivamente a essas áreas foi pequena, se comparada aos fragmentos no altiplano, fato que aparentemente está associado às diferenças existentes entre os fragmentos contidos nos interflúvios e os fragmentos do altiplano. A atividade dos anfíbios foi concentrada no período quente e úmido, diminuindo à medida que se aproxima o ápice da estação fria e seca. Com base na análise de similaridade, observou-se a formação de agrupamentos com alta sobreposição. Entre esses agrupamentos, destacaram-se aqueles formados por espécies com atividade de vocalização prolongada, mas que diferiram quanto ao período de maior atividade (início e final da estação chuvosa) bem como, aqueles constituídos por espécies com período de vocalização mais curto, restrito a poucos dias, e que também diferiram no mês de pico de atividade (início e final da estação chuvosa). Com isso acreditamos que as diferenças quanto à distribuição temporal dos organismos da comunidade sejam importantes na partilha de recursos e no ajuste das espécies, fato que contribuiu para o elevado número de anfíbios observados e na coexistência dos táxons na área de estudo.

Diagnóstico populacional e comportamental de saguis-de-tufo-preto (Callithrix penicillata) em ambiente peri-urbano

The black-tufted-marmoset (Callithrix penicillata), abundant in the southeastern state of São Paulo, is an exotic and invasive species . The present study aimed to study the behavior and make monitoring a population black-tufted-marmoset in man-made environment. The observations were made following the method of scan sampling, which consists of continuous observations with a duration of three minutes with a fifteen-minute intervals between one record and another. The individuals are monitored at two locations on campus, where two groups were identified (with a mean of 3.50 ± 2.06 individuals) totaling 291 hours and 30 minutes of observation. Were determined tree layers used, and observed that the group of EC preferably utilizes the highest stratum, while the group of LCF uses the middle and lower strata. Types of vocalization, such as calling, interaction and alert and frequency and percentage of these were also observed. The food items consumed by the groups that are similar in the two study sites, mostly sap and leaves were diagnosed. From observations of behavioral patterns was possible to construct an ethogram of the species ' Luiz de Queiroz ' campus, comprising the behaviors of vocalization, locomotion, foraging, game, among others. The results may be useful for development of management techniques and for subsequent studies

Spatio-temporal distribution of calling male frogs in Morro do Diabo State Park (Southeastern Brazil): implications for conservation and management in a seasonally dry tropical forest

The aims of this study are to determine how anuran calling males are spatially and temporally distributed in the Morro do Diabo State Park (MDSP), and to test for indicator species in different breeding habitats. We found high species turnover among breeding habitats of different hydroperiods. Our results indicate that spatial partitioning is more important than seasonal occurrence in permitting species coexistence at MDSP. Indicator Species Analysis identified one species associated with a local stream, one species associated with permanent ponds, two species associated with temporary ponds, and three species associated with a semipermanent pond. Guilds of species do not appear to stratify their distributions throughout the year, since most species occur during the rainy and warm months and are thus temporally overlapping. The main conservation implication of our work is the need to protect the different areas of the park where these unique breeding habitats, and their associated anuran assemblages, are found.

O ensino de redação em sites: diálogos em rede

We know that studies on reading and writing take place within the Linguistic for several decades and, with de computer, the language entered the network and this is opening a learning space for writing classes, no more reduced to a classroom but expanded to a universe that has no geographical boundaries, namely de Internet. Our research fits into this context and is part of the project The discourse on writing practices in contemporary Brazilian media: the art making, the pedagogical practice, and the production of meaning to develop discourse analysis on the practice of writing on sites dedicated to teaching and learning of this practice. The main objective of this research is to investigate the relationship between school attendance of redaction - made here as discourse gender, as you know Bakhtin - and the discourse of the sites that constitute our corpus. We set out the hypothesis that the sites are intended for the teaching/learning of writing seeking to create virtually teaching imaginarily conditions similar to those that exist in school attendance of the Portuguese language. We are interested in, therefore, observe, discursively, as the image is created of the interlocutors to which they are intended considering that the enunciators are not in front of those who occupy the place of real students, because they are virtual students. We, too, to know as the gender class manifested itself in those sites, as these sites dialogue with the face-to-face class in relation to ideology, the function of the teacher, the conception of language and writing. The constitution of the corpus was from search tools on the internet. The sites that we analyzed were: alunosonline.com.br, brasilescola.com.br, coladaweb.com.br, guiadoestudante.com.br, infoescola.com.br, mundoeducação.com.br, mundovestibular.com.br, português.com.br, professorjuscelino.com.br and redaçãodissertativa.com.br.
