1. Estrutura e diversidade de trechos de Cerrado sensu stricto às margens de rodovias no estado de Minas Gerais
Resumo Estradas são um dos principais fatores de degradação conhecidos do Cerrado, pois, apesar de sua relevância econômica, causam recortes em extensas massas contínuas de biota natural. De acordo com o Código Florestal Brasileiro, a vegetação às margens de rodovias deve ser considerada como de preservação permanente. Entretanto, escassos são o

3. Phytosociological Survey of Sugarcane Crop Weeds in Different Agroecological Areas in Tucumán Province, Argentina
RESUMO: As plantas daninhas constituem o principal fator limitante na produção de agroecossistemas de cana-de-açúcar argentinos. O objetivo deste trabalho foi analisar a composição florística e fitossociológica de plantas daninhas na cultura da cana-de-açúcar em diferentes regiões agroecológicas. Entre 60 e 90 dias a partir do surgimento da cultu

4. Species Diversity and Community Structure of Arthropod Pests and Predators in Flax, Linum Usitatissimum L. from Darjeeling (India)
ABSTRACT The species richness and relative abundances of different aboveground plant-dwelling pest and predator species were assessed in flax (Linum usitatissimum L.) ecosystem under mid-hill conditions of eastern Himalayas. The experiment was conducted in winter seasons during 2004-2013 at the Regional Research Station (Hill Zone), Uttar Banga Krishi Viswav

5. Spatial Variability of Soil Fauna Under Different Land Use and Managements
ABSTRACT Geostatistics allows the evaluation of the distribution pattern of data with high spatial variability in agricultural systems. This study aimed to evaluate the spatial variability of biological diversity indices of soil fauna under different land (agriculture and forest). Samples were collected in seven areas (millet, soybean, corn, eucalyptus, past

6. Forecasting the impact of an invasive macrophyte species in the littoral zone through aquatic insect species composition
ABSTRACT Invasive macrophytes threaten freshwater ecosystem biodiversity. We analyzed the impact of the invasive white ginger lily (Hedychium coronarium J. König, Zingiberaceae) on aquatic insect assemblages living in the littoral zone of a tropical reservoir. We took aquatic insect samples in the littoral zone on four main vegetal profile banks: white ging

7. Longitudinal impact of clinical and socioenvironmental variables on oral health-related quality of life in adolescents
Abstract The aim of the present study was to investigate the impact of oral diseases, socioeconomic status, and family environmental factors on changes in the perception of oral health-related quality of life (OHRQoL) in adolescents. A prospective cohort study was conducted in Juiz de Fora, Minas Gerais, Brazil, with a sample of 286 twelve-year-old adolescen

8. Spatial distribution of Culicidae (Diptera) larvae, and its implications for Public Health, in five areas of the Atlantic Forest biome, State of São Paulo, Brazil
ABSTRACT In view of the adaptive ability of mosquitoes and their role in the transport of infective agents, entomological surveys undertaken in transitional environments are very important for the determination of the risk they represent for Public Health. Among the principal vectors of the infectious agents involved in the occurrence of important arboviruse

9. The impact of social determinants on schoolchildren’s oral health in Brazil
The aim of this study was to evaluate the impact of socioeconomic status, home environment, and self-perception of health conditions on schoolchildren’s dental caries experience. A total of 515 twelve-year-old schoolchildren from Juiz de Fora, State of Minas Gerais, Brazil, were selected into a random multistage sample. The schoolchildren were examined

10. Occurrence of culturable soil fungi in a tropical moist deciduous forest Similipal Biosphere Reserve, Odisha, India
Similipal Biosphere Reserve (SBR) is a tropical moist deciduous forest dominated by the species Shorea robusta. To the best of our knowledge their rich biodiversity has not been explored in term of its microbial wealth. In the present investigation, soil samples were collected from ten selected sites inside SBR and studied for their physicochemical parameter

11. FLORÍSTICA, ESTRUTURA E DINÂMICA EM UMA FLORESTA OMBRÓFILA MISTA NO NORTE DO ESTADO DE SANTA CATARINA
The floristic composition, horizontal structure, diametrical distribution and the dynamics (ingrowth, increment, mortality) were evaluated in a remaining of a Ombrophyllous Mixed Forest, located in the National Forest of Três Barras, Três Barras City, Santa Catarina State, within a period of 5 years (2004-2009). In 2004, it were installed and measured 26 p

12. 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
