Taxonomia e biogeografia da espécie politípica Herpsilochmus rufimarginatus (TEMMINCK, 1822) (Aves: THAMNOPHILIDAE)

The genus Herpsilochmus is composed mainly of cryptic species, among them is Herpsilochmus rufimarginatus, which is currently represented by four subspecies: H. r. rufimarginatus, H. r. frater, H. r. scapularis and H. r. exiguus. Differences in plumage and vocalization suggest that there are more than one species involved in this complex. Thus this and other subspecific taxa need urgent revision, the disjunct distribution of this species also allows us to infer the relationship between birds that occur in this biome and / or different centers of endemism. This study aims to make a taxonomic revision of the taxa included in the complex time Herpsilochmus rufimarginatus based on morphological, morphometric, vocals and geographical distribution of this bird. Besides creating distribution models current potential and make the reconstruction of the distribution bygone using ecological niche modeling, and testing the niche conservatism and divergence between different subspecies. Consultations for examination of the skins of specimens of the museums: Museum of Zoology, University of São Paulo (MZUSP), National Museum of Rio de Janeiro (MN) and Emilio Goeldi Museum of Pará (MPEG), and the skins deposited at the collection of Ornithological Federal University of Rio Grande do Norte (COUFRN). We studied the following measures length of specimens: exposed culmen, culmen and total culmen nostril, tarsus, wing and tail flattened. The voice analysis was performed with vocalizations banks and / or digital banks people where 17 voice parameters were measured. This information and more available in the literature were used to assemble a bunch of data under the limit distribution of taxa and generate ecological niche models. This analyzes carried out in the program Maxent, having as model selection criterion the AUC, and the models were greater than 0.80 are considered good models. Environmental data for the realization of the modeling were downloaded on the website of Worldclim. The morphometric information, vocals and geographic distribution point for the separation of these taxa to be considering various uni and multivariate analyzes. The potential distribution models performed well (AUC> 0.80), and its distribution associated with environmental characteristics of the Amazon forest and Atlantic forest (forests of south and southeast, northeast and forest). The reconstruction of the distribution indicates a possible contact between the southern part of the Atlantic forest in the northern part of the Amazon. The analysis of niche overlap showed a low overlap between taxa and comparisons between the null model and the generated overlay link probably occurring niche conservatism. The data suggest that the taxa that occur in the Amazon and Atlantic forest represent three distinct species

Caracterização morfodinâmica do estuário do Rio Açu, Macau/RN

Estuaries are coastal environments ephemeral life in geological time, derived from the drowning of the shoreline as a function of elevation relative sea level. Such parallel systems is characterized by having two sources of sediment, the river and the sea. The study area comprises the Acu River estuary, located on the northern coast of Rio Grande do Norte State, in a region of intense economic activity, mainly focused on the exploration of oil onshore and offshore, likely to accidental spills. In the oil sector are developed for salt production, shrimp farming, agriculture, fisheries and tourism, which by interacting with sensitive ecosystems, such as estuaries, may alter the natural conditions, thus making it an area susceptible to contamination is essential in understanding the morphodynamic variables that occur in this environment to obtain an environmental license. Information about the submarine relief the estuaries are of great importance for the planning of the activity of environmental monitoring, development and coastal systems, among others, allowing an easy management of risk areas, and assist in the creation of thematic maps of the main aspects of landscape. Morphodynamic studies were performed in this estuary in different seasonal periods in 2009 to observe and quantify morphological changes that have occurred and relate these to the hydrodynamic forcing from the river and its interaction with the tides. Thus, efforts in this area is possible to know the bottom morphology through records of good quality equipment acquired by high resolution geophysical (side-scan sonar and profiler current by doppler effect). The combination of these data enabled the identification of different forms of bed for the winter and summer that were framed in a lower flow regime and later may have been destroyed or modified forms of generating fund scheme than the number according Froude, with different characteristics due mainly to the variation of the depth and type of sedimentary material they are made, and other hydrodynamic parameters. Thus, these features background regions are printed in the channel, sandy banks and muddy plains that border the entire area

Bancos de sangue de cordão umbilical e placentário para uso familiar, de caráter privado, no Brasil: subsídios técnicos, legais e éticos para uma análise de implementação

Os bancos de sangue de cordão umbilical e placentário foram criados a partir da comprovação de que o sangue de cordão umbilical e placentário (SCUP) é uma fonte rica em células progenitoras hematopoéticas (CPH) e alternativa às células provenientes da medula óssea para transplante, fato que gerou o interesse pelo armazenamento das células nele contidas. A legislação brasileira distingue bancos para uso alogênico não aparentado (públicos) e para uso exclusivamente autólogo (privados). Por sua vez, o armazenamento de SCUP para uso familiar (doação dirigida) pode ser realizado em bancos de sangue de cordão umbilical e placentário públicos, serviços de hemoterapia ou centros de transplante, quando há um membro da família do nascituro com doença diagnosticada e que necessite de transplante de CPH como tratamento. Apesar de a legislação ser clara, a Anvisa tem identificado o interesse sobre a possibilidade da liberação de unidades de SCUP, armazenadas em bancos autólogos, para a utilização de outrem, familiar, além do recém-nascido beneficiário. O objetivo do trabalho visa promover a reflexão sobre uma possível modificação dos parâmetros legais nacionais que regem os bancos de SCUP autólogo, tornando-os bancos com vistas ao uso familiar, por meio da exposição dos principais elementos relacionados ao tema. O estudo analisou os critérios técnico-sanitários legais para regulamentação dos bancos; descreveu as características das CPH de diversas fontes e tipos de doação para transplante; contextualizou a relação com os princípios da Bioética; avanços sobre terapia e pesquisas relativas às CPH; e discutiu possíveis riscos envolvidos no processo.

Os Brachyura semiterrestres Crustacea, Decapoda de Ilha Comprida, SP., Brasil

This work aims to analyse the faunistic composition of ''Ilha Comprida, SP, Brasil, in relation to semiterrestrial crabs. The collects were done during one year. The animals were handy sampled, and the colleting area comprised from Cananeia proximities to Icapara bar, towards north, including beaches, sand banks and mangroves. After each sample the animals were identified. The results obtained were similar those presented for other estuarine regions in São Paulo north coast. With reference to the species from Parana coast, we have got 2 species more. The crabs recorded are distributed in 3 Decapod families: Grapsidae, Ocypodidae and Xanthidae.

New Neotropical species of Ceraeochrysa Adams (Neuroptera: Chrysopidae)

Species of Ceraeochrysa Adams are distributed from southeast Canada to Argentina. Larvae feed on aphids, thrips, white flies, mites, and neonatal larvae of Lepidoptera in varied agroecosystems. Seven species are known in Venezuela, viz. Ceraeochrysa achillea Freitas & Penny, C. angulata (Navas), C. bitacornua Freitas & Penny, C. caligata (Banks), C. cubana (Hagen), C. everes (Banks), and C. valida (Banks). In this study, three species are described as new to science, Ceraeochrysa melaenopareia sp. nov., Ceraeochrysa pittieri sp. nov., and Ceraeochrysa torresi sp. nov.
