1. Pollen morphology of selected species of Passiflora L. (Passifloraceae) from the Atlantic Forest
Pollen grains from twelve species of the Passifloraceae family from the Brazilian Atlantic Forest were analyzed: Passiflora subg. Astrophea (1sp.), P.subg. Decaloba (1sp.) and P.subg. Passiflora (10spp.). The current study aims to acquire additional information and feature the pollen morphology of the herein studied species to help setting a more precise tax

2. A molecular contribution to the controversial taxonomical status of some freshwater snails (Caenogastropoda: Rissooidea, Cochliopidae) from the Central Andes desert to Patagonia
For over 40 years malacologists have been discussing the taxonomical status of Heleobia species, an enigmatic genus from Cochliopidae family (Caenogastropoda: Rissooidea). As with other rissooidean families, the considerable character convergence and the paucity of anatomical synapomorphies has proved to be a problem in resolving cochliopid phylogenetic rela

3. Filogenia e biogeografia das espécies de actinote hübner, 1819 (Nymphalidae : Heliconinae) / Phylogeny and biogeography of species of actinote hübner, 1819 (Nymphalidae : Heliconinae)
Many aspects and details of the origin, evolution and biogeographical patterns of butterflies are not yet fully comprehended. The phylogenetic relationships among most butterfly groups remained unknown until recently. Phylogenetic studies have been based mainly on morphological characters of adults, although characters of immature stages had increased in use

4. Sistemática de Chironomidae (Insecta: Diptera) associados a esponjas de água doce
The first reports of Chironomidae in sponges date from the beginning of the 20th century, beginning with Xenochironomus Kieffer and Demeijerea Kruseman in North America. Since then, few species in these genera have been described and it was not until 2004 that a species in another genus (Oukuriella Epler) was reported as having larvae living in freshwater sp

5. Redescription of a Dasypodini (Xenarthra, Cingulata) from the Quaternary of São Paulo, Brazil, and remarks on the genus Propraopus Ameghino, 1881. / Redescrição de um Dasypodini (Xenarthra, Cingulata) do quaternário do Estado de São Paulo e considerações sobre o gênero Propraopus Ameghino, 1881
This work presents the comparative description of the skull, postcranium and osteoderms of the Dasypodini (Xenarthra, Cingulata) MNRJ 552-V, collected in the quaternary deposits of Gruta de Itaporanga, Sorocaba-SP, Brazil. The skull was CT scanned and compared to those of extant taxa of all three Dasypodidae subfamilies, while the postcranium was compared to

6. Considerações filogenéticas e taxonômicas na tribo Hureae Dumort. (Euphorbioideae- Euphorbiaceae) / Phylogenetics and taxonomics considerations of the tribe Hureae (Euphorbioideae-Euphorbiaceae).
Euphorbiaceae s.s., with five subfamilies and about 6.300 tropical and subtropical species, is one of the most complex and diversified angiosperm lines. Under a phylogenetic perspective, the approaches concerning the family are scarce and restricted to the highest levels. Among the Euphorbiaceae subfamilies, Euphorbioideae is prominent since it aggregates th

7. Características vegetativas e reprodutivas das plantas e fatores abióticos do meio e suas relações com a alocação de biomassa floral e a seleção sexual em angiospermas / Vegetative and reproductive characteristics of plants and abiotic factors of the environment and their relations with floral biomass allocation and sexual selection in angiosperms
Plants are sessile organisms exposed to the effects of environmental stress. The flowers are fundamental structures in the evolution of angiosperms, because through them is sexual reproduction. For this, the flowers exhibit strategies that help the plant to achieve better reproductive success. Animals visit flowers in search of resources, however, to carry p

8. Ser mãe eu sei, o que agora falta é social: sobre o processo de constituição da identidade profissional no Acolhimento Institucional de Crianças
This work aimed to comprehend how social mothers give meaning to their daily life in an Institutional Shelter and to analyze their inter-relations with the making up of Professional identity. We were guided by a Historical-material dialect of man and world and the expression of this in Psychology which considers the making up of a person as a human being as

9. Orchidaceae nativas da região central de São Paulo, Brasil : florística, interação com forófitos, proposta de novas espécies e propagação in vitro de uma espécie ameaçada de extinção / Native Orchidaceae of the central region of São Paulo, Brazil: floristic, interaction nested with host tree, new species proposed and in vitro propagation of threatened of extinction species
Aiming to know the sorts of Orchidaceae of the central region of the State of São Paulo, from 1996 and more intensively from 2005, visits were carried out in 125 forest fragments of 23 local municípios, with weekly periodicity and also, fortnightly. The collect were assistematics, being each fragment visited in the biggest number of points. The species not

10. RelaÃÃes filogenÃticas de abelhas indÃgenas sem ferrÃo do tÃxon Melipona Illiger, 1806 (Apidae: Meliponina) baseadas em seqÃÃncias parciais da regiÃo its1 do DNA ribossÃmico nuclear / FilogenÃticas relations of aboriginal bees without sting of tÃxon Melipona Illiger, 1806 (Apidae: Meliponina) based in partial sequences of the region its1 of the nuclear ribossÃmico DNA
O presente trabalho foi conduzido no perÃodo de abril de 2006 a marÃo de 2008, nos departamentos de Zootecnia e de Biologia, da Universidade Federal do CearÃ. O objetivo desta pesquisa foi investigar, atravÃs de dados moleculares, as relaÃÃes filogenÃticas de algumas abelhas indÃgenas sem ferrÃo do tÃxon Melipona Illiger, 1806, nativas do Brasil. P

11. A mitochondrial metazoan phylogeny / Uma filogenia mitocondrial de metazoários
Inferring the evolutive relations between the animal phyla has been a formidable challenge to Science. The animal phyla represent quite distinct baupläne (body architectures) and are, therefore, difficult to compare. At the same time, their fossil record converges mostly to the same period on the geological scale. The recent availability of molecular data h

12. Investigação sobre a diversidade microbiana e a filogenia de arquéias e bactérias em consórcios anaeróbios metanogênicos, originados de sedimentos estuarinos enriquecidos com clorofenóis / Investigation on the microbial diversity and phylogeny of archaea and bacteria in anaerobic methanogenic consortium from enriched estuarine sediments with pentachlorophenol (PCP) and 2,6-dichlorophenol (2,6-DCP)
Este trabalho investigou a diversidade microbiana e a filogenia de arquéias e bactérias em consórcios anaeróbios metanogênicos, originados de sedimentos estuarinos enriquecidos com pentaclorofenol (PCP) e 2,6-diclorofenol (2,6-DCP). Para tanto foram construídas bibliotecas genômicas e utilizados métodos moleculares independentes de cultivo como a Ele
