Chave de identificação interativa de múltiplas entradas para espécies da família Lauraceae da Reserva Natural Vale, Linhares - ES

Foi elaborada uma chave interativa de múltiplas entradas para a identificação de 50 espécies da Família Lauraceae presentes na Reserva Natural Vale, Linhares-ES. Desenvolvida a partir da versão livre do Programa Lucid® 3.3, apresenta caracteres botânicos de marcação livre e não sequencial, que elimina as espécies as quais não atendem aos critérios selecionados até a identificação do material. Para tanto foi confeccionada uma matriz de caracteres relacionados aos táxons. Foram incluídas ilustrações no final do trabalho já que a versão utilizada do programa compromete a resolução dessas na própria chave. Há uma cópia da chave com o instalador do programa e instruções para uso no CD-ROM entregue junto com o trabalho. Futuramente estará hospedada no site do programa. A versão apresentada no trabalho é preliminar e será concluída posteriormente com a versão paga do programa. A utilização das chaves interativas facilita e dinamiza o processo de identificação dos táxons, contribuindo para a difusão do conhecimento biológico e de programas voltados ao reconhecimento e conservação da biota

Sinalização visual e biologia reprodutiva de Dendropsophus werneri (Anura: Hylidae) em área de Mata Atlântica no estado do Paraná, Brasil

We studied the reproductive biology and visual signaling of Dendropsophus werneri, whose distribution is limited to the Atlantic Rain Forest. The fieldwork was carried out in the Estação 2 do IAPAR, municipality of Morretes, state of Paraná, Brazil, from August 2006 to March 2007. Additional information on reproduction was gathered in the Reserva Natural Salto Morato, municipality of Guaraqueçaba, state of Paraná, Brazil, from September 2006 to March 2007. Males were smaller than females. Males called throughout all the study period in Morretes, but were active only during three months in Guaraqueçaba; males called from low vegetation along the edge of temporary ponds in open areas. The visual signaling was observed in two contexts: (1) aggressive behaviors between two males and (2) during the reproduction, by amplectant males. In the territorial behavior, males exhibited both aggressive and mixed calls, visual signaling as well as physical combats. We also recorded satellite behavior in four males. The mean egg number per clutch was 244 ± 32 eggs, varying between 188 and 310 eggs. We observed two reproductive modes: Mode 1 and Mode 24. In the present study, Dendropsophus werneri showed elaborated social interactions involving visual signaling, territorial behavior, mating bahavior with tactile stimuli, and two different reproductive modes, demonstrating its complex reproductive biology.

Visão contemporânea sobre pinos anatômicos

As an alternative to improve the adaptation of prefabricated posts in flared canals and weakened roots, the option is for relining prefabricated pin, known as a technique of anatomical post. This technique, which can be made with composite resin increases the adjustment post to the walls of the canal and reduces the cementing line, causing the retaining post is less dependent on the mechanical properties of the cementing agent. This article aims to provide an overview of anatomical posts, specifically in the last two decades, based on studies extracted from Scielo, Scopus and Pubmed, referring to the following terms of MeSH Data Base: custom made fiber post, indirect fiber glass posts, root canal therapy and post and core tecnique. According to the literature review in this article, it can be concluded that this technique has been used by several authors and has been shown effective and promising, it creates an individualized retainer with better adaptation and decreased mechanical imbrication cementing line .

Tecnologias de gênero, masculinidades e apriosionamentos na execução penal

The study articulates the relations of power / knowledge in the production of crime and operationalization of the law, the subtle way in which technologies of gender naturalize actions and reactions in relationships, partnerships and daily struggles between staff and prisoners and the processes of subjectivity in contemporaneity . This study has as epistemological matrix the genealogy proposed by Michel Foucault, who has allowed diverse pathways as document reviews, semi-structured interviews, performance groups and courses. The interweaving of the forces and discourses has engendered the impact of technologies on gender, especially masculinity, in the present relations between staff and prisoners. The impact of this relationship puts on display the modulations of subjectivity in a continuum of oscillation between normalizing and singularizing modes of subjectification.

A família Myrtaceae na reserva particular do patrimônio natural da Serra do Caraça, Catas Altas, Minas Gerais, Brasil

This is a floristic survey of Myrtaceae in the Serra do Caraça, Minas Gerais. Fifty two species were found belonging to 12 genera - Myrcia with 17 species, Eugenia with nine, Campomanesia and Myrciaria with five species each, Psidium with four, Siphoneugena with three, Blepharocalyx, Calyptranthes, Marlierea and Myrceugenia with two species each, and Accara and Plinia with one species each. Descriptions of the genera and species, identification keys, geographical distributions, illustrations and comments are provided. © 2005 Instituto de Ciências Biológicas - UFMG.

Measurement of the natural variation of 13C:12C ratio in leaves at Reserva Ducke Forest, central Amazonia

Investigation of carbon isotope fractionation by plants was carried out at two sub-areas located in Reserva Ducke, central Amazonia: open reserve (virgin forest with low density of plant species); and closed reserve (virgin forest with high density of plant species). Preliminary results (δ‰ 13C: 12C values, PDB) of leaf analysis at different plant heights indicate the following: Eschweilera matamata Hub. (Lecythidaceae), common name 'matamata', -31.55±0.61; Protium heptaplyllum March. (Burseraceae), common name 'breu branco', -32.34±1.39; Calophyllum brasiliense Camb. (Guttiferae), common name 'jacareúba', -30.72±0.23; Scleronema micrantthum Ducke. (Bombacaceae), common name 'cardeiro'. -28.81±0.68; and Carapa guianensis Aubl. (Meliaceae), common name 'andiroba', -31.07±0.51. It is possible that the plant species analysed belong to the C3 photosynthetic cycle. In general, the species in the open reserve show differences of the order of 1.66±0.34‰ (greater in 13C) as compared with the same species in the closed reserve. The old leaves show differences in the relative isotopic enrichment (δ) of the order of 1‰, being smaller in new leaves in both reserves. The probable occurrence of an isotopic gradient from the lower (2-5 m) to the upper part (15-20 m) of the plant, of the order of 1.3‰, smaller in 13C, in species from the dense forest was noted. However, only two plants from each species were analysed during a two-year period, data obtained to far are still preliminary, and results should, therefore, be revised. Moreover, according to the literature, the natural carbon isotope fractionation by plants shows metabolic, physiological and environmental dependence. © 1991.
