27. Understory structure in riparian fragments of atlantic rainforest in the extreme north of Pernambuco, Brazil / Estrutura do sub-bosque em fragmentos ripÃrios na floresta atlÃntica do extremo norte, Pernambuco, Brasil
Deleterious changes in fragments of forest communities have been often associated to biotic and abiotic changes related to area and edge effects. The understory is an important component of forest communities and exhibits a clear response to the process of fragmentation, due to its susceptibility to such effects. In the Northern section of the Atlantic Fores

28. Forest fragments' contribution to the natural biological control of Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) in Maize
The present work evaluated the influence of forest distance on predatory solitary wasps' abundance and richness and its relation to the natural biological control of the fall armyworm (Spodoptera frugiperda Smith - Lepidoptera: Noctuidae) in maize. The study consisted of two parallel lines of six experimental maize plots located at an increasing distance fro

29. The effects of four types of anthropogenic disturbances on composition and abundance of terrestrial isopods (Isopoda: Oniscidea)
The Brazilian Atlantic Forest is currently reduced to about 12% of its original range. Among the components that make up its great diversity, there are species with the potential to be bioindicators, which can be very important for conservation-oriented studies. This study compares the species composition, abundance and sex ratio of terrestrial isopods in si

30. Efeito da fragmentação sobre a estrutura de populações de Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae) no sul do Brasil
Fragmentation of habitat is the transformation of a continuous natural landscape into habitat patches or fragments, and may result from human settlements, agriculture, resource extraction and/or logging. Besides the influences of habitat loss, populations that remain in these fragments experience conditions similar to those of the surrounding matrix: the pro

31. Desenvolvimento de filmes de ZnO para aplicação em fotocatálise
This study was dedicated to the synthesis and characterization of ZnO films grown on aluminum and graphite substrates. The synthesis was carried out through the hydrothermal method that is simple and low cost. The association of different characterization techniques allowed the study of electronic and structural properties of the films in order to evaluate t

32. Influence of row spacing reduction on maize grain yield in regions with a short summer.
The interest in reducing maize row spacing in the short growing season regions of Brazil is increasing due to potential advantages such as higher radiation use efficiency. This experiment was conducted to evaluate the effect of row spacing reduction on grain yield of different maize cultivars planted at different dates. The trial was conducted in Lages, in t

33. TV on web: courses of reelaboration of audiovisual genres in the era of transmedia / A TV na web: percursos da reelaboraÃÃo de gÃneros audiovisuais na era da transmÃdia
This research aims to discuss the possibilities of reworking television genres, due to transmedia phenomenon, which takes those genres to digital communication platforms. Accordingly to that, the research tries to capture evidences of change in two television genres â the soap opera and the newscast â in the edge of its migration to YouTube video repositor

Estrutura e riqueza de hepáticas (Marchantiophyta) epifíticas em áreas fragmentadas de Cerrado com borda natural e antrópica / Estrutura e riqueza de hepáticas (Marchantiophyta) epifíticas em áreas fragmentadas de Cerrado com borda natural e antrópica / Structure and richness of the epiphytic liverworts (Marchantiophyta) in fragmented areas of Cerrado with natural edge and anthropogenic / Structure and richness of the epiphytic liverworts (Marchantiophyta) in fragmented areas of Cerrado with natural edge and anthropogenic
The damage caused by the proliferation of edge in forest cover, referred to as edge effects are extensive, may occur over large spatial scales influencing species composition, structure and ecological processes in boundaries of ecosystems. However, studies have shown highly variable response patterns of the taxonomic group studied in relation to the landscap

35. Fragmentação florestal, dinâmica e ecologia da paisagem na bacia hidrográfica do rio Itapemirim, ES. / Forest and dynamic fragmentation of landscape ecology on the Itapemirim river hydrographic basin, ES.
This study had as the most important objective to analyze the structure of forest landscape on the Itapemirim ES basin river, using quantitative methods with indexes of landscape ecology, aiming the selection of suitable areas for environmental conservation; and to study the influence of the edge effect on the different sizes of these fragments. Initially th

36. Resposta da comunidade de formigas aos atributos dos fragmentos e da vegetação em uma paisagem da Floresta Atlântica nordestina
The objective of this study was to determine the effects of forest fragmentation on ant richness in a landscape of Atlantic Forest in Northeast Brazil. More specifically, the ant richness was related to the attributes of fragments (area and distance from the fragment central point to the edge), landscape (forest cover surrounding the fragments), and tree com
