Tree structure and richness in an Atlantic Forest fragment: distance from anthropogenic and natural edges

Approximately 7.2% of the Atlantic rainforest remains in Brazil, with only 16% of this forest remaining in the State of Rio de Janeiro, all of it distributed in fragments. This forest fragmentation can produce biotic and abiotic differences between edges and the fragment interior. In this study, we compared the structure and richness of tree communities in three habitats - an anthropogenic edge (AE), a natural edge (NE) and the fragment interior (FI) - of a fragment of Atlantic forest in the State of Rio de Janeiro, Brazil (22°50'S and 42°28'W). One thousand and seventy-six trees with a diameter at breast height > 4.8 cm, belonging to 132 morphospecies and 39 families, were sampled in a total study area of 0.75 ha. NE had the greatest basal area and the trees in this habitat had the greatest diameter:height allometric coefficient, whereas AE had a lower richness and greater variation in the height of the first tree branch. Tree density, diameter, height and the proportion of standing dead trees did not differ among the habitats. There was marked heterogeneity among replicates within each habitat. These results indicate that the forest interior and the fragment edges (natural or anthropogenic) do not differ markedly considering the studied parameters. Other factors, such as the age from the edge, type of matrix and proximity of gaps, may play a more important role in plant community structure than the proximity from edges.

Flora e aspectos auto-ecológicos de um encrave de cerrado na chapada do Araripe, Nordeste do Brasil

This study subject to investigate the floristic composition and richness, the reproductive phenological patterns, the dispersal syndromes and life forms of species of a disjunt cerrado in semiarid climate at Araripe plateau during a one year period. We found 107 species and 41 families. Fabaceae, Myrtaceae, Poaceae, Apocynaceae, Euphorbiaceae and Malpighiaceae showed the largest number of species. For 47 of the woody species found, we studied the geographical distribution based on 27 papers of the Brazilian cerrados. Twelve species are of widespread occurence in the cerrado, and 13 are restricted to the Araripe plateau. Zoocory, autocory, and anemocory are the predominant syndromes of dispersal. The predominant life forms were phanerophytes (50.7%), hemicriptophytes (14.9%) and camephytes (13.1%). The cerrado of Araripe have lower species richness than continous cerrados, but a similar pattern of reproductive phenology, dispersal syndromes and life forms in more humid zones.

Reproductive biology of Davilla kunthii A. St-Hil. (Dilleniaceae) in Central Amazonia

This survey aimed at describing the interactions of floral visitors and Davilla kunthii A. St.-Hil. as well as characteristics of its reproductive biology in Itacoatiara, state of Amazonas, Brazil. Tests of the breeding system were performed. The guild of visitors was described according to richness, abundance, relative frequency and constancy. The breeding system tests indicated that D. kunthii is self-compatible. The pollination system was characterized as generalist, with 39 visitor species, from three different orders. Bees were the main group of pollinators, thus some behavioural aspects were described. Th e period of highest foraging activity was between 7 and 10 am. Some species presented agonistic and monopolistic behaviour. Given the behaviour and destructive potential, the Curculionidae seem to have a greater impact as seed predators than pollinators.

Sistema Nacional de Educação articulado ao Plano Nacional de Educação

This text which discusses the central theme of the National Conference on Education (CONAE), held in Brasília from 28th March to 1st April 2010, deals with the concept of a National System of Education in articulation with the National Plan of Education. To that end, after pointing to the basic uses of the concept of system, it discusses the question of the National System of Education exploring the federative question in order to reveal the complete compatibility of the organization of the National System of Education with the federative regime. Thereafter, it deals with the historical meaning of the National Plan of Education demonstrating that the plan is a demand of the system, since planned action is implicit in systematized education. Thus the National Plan of Education is fulfilling those goals and objectives for which it is responsible.

A moradia estudantil universitária como tema na produção científica nacional

This study analyses the national scientific production about college students' residence halls. The country's main data bases and electronic sites of several Brazilian higher education institutions were checked and 23 studies, published between 2000 and 2009, were found. The results of our analysis point to different focuses, which can be grouped into three categories: students who live in residence halls, residence halls themselves and actions for student assistance. Although there is large foreign scientific production about college student housing, the national production on this theme is still scarce, and the idea of student residence halls as educational spaces is still very incipient. The study points out to the need for investigating the living conditions in these places, and the impacts of this kind of habitation on students. Considering that student housing is an institutional responsibility, these studies potentially subsidize measures for proper educational conditions for college students.
