1. Hysterosalpingography: Balloon Catheter or Metal Cannula?
ABSTRACT The Brazilian Atlantic Forest (BAF) is one of the biodiversity hotspots, but in the last decades, it has been fragmented due to agricultural and urban-industrial expansion, which has a strong impact on forest fragments. The goal of this study was to analyze the Biotic Integrity Index (BII) in fragments of BAF in two medium-sized cities in Southeaste

3. Richness of Chrysomelidae (Coleoptera) depends on the area and habitat structure in semideciduous forest remnants
RESUMO A área de uma mancha de habitat pode aumentar a riqueza local de espécies tanto diretamente (pelo balanço entre imigração e extinção) quanto indiretamente (por aumentar a heterogeneidade do habitat e/ou como efeito do esforço amostral). Ambientes mais heterogêneos apresentam maior variedade de recursos e condições permitindo a coexistência

4. Agroforestry systems and understory harvest management: the impact on growth and productivity of dual-purpose wheat
Abstract: The objective of the study was to evaluate the growth and production efficiency of forage-grain dual-purpose wheat in two arrangements and four agroforestry systems (Intercrop-I and Intercrop-II), as well as to evaluate crop management for the wheat crops in two planting seasons (Crop Season I-2014 and Crop Season II-2015. The experiment was condu

5. Mimosa scabrella Benth. as Facilitator of Forest Successional Advance in the South of Brazil
ABSTRACT Pioneer species have the potential to colonize disturbed environments, contributing to the establishment of other species and driving the dynamics and advancement of the structure of forest communities. The aim of this study was to assess the evolution of floristic-structural composition in the regenerating stratum of communities formed in the Mimos

6. Estimativa de impactos da extração seletiva de madeiras na Amazônia utilizando dados LIDAR
Resumo As atividades de manejo florestal são consideradas importantes para o desenvolvimento sustentável no Brasil. Tais atividades, entretanto, exigem monitoramento rigoroso que muitas vezes é de difícil operacionalização. O mapeamento das áreas afetadas pela exploração seletiva de madeira e a mensuração dos impactos decorrentes da exploração f

7. Effect of Leaf Quality on Herbivory of Three Atlantic Forest Species
ABSTRACT The present study evaluated the relationship between herbivory and leaf quality of three abundant tree species (Cupania oblongifolia Mart., Siparuna guianensis Aubl. and Xylopia sericea St. Hill.) in the understory of a eucalyptus plantation and an adjacent Atlantic Rainforest fragment. Herbivory differed among species, since X. sericea was less att

8. Phytosociology of Native Species in the Understory of a Corymbia citriodora Stand in Espírito Santo State, Brazil
ABSTRACT This study is based on the hypothesis that unmanaged plantations of commercial species do not prevent understory colonization by native species. The research aimed to describe the floristic composition and structure of native arboreal species in the understory of a Corymbia citriodora stand. To this end, 112 plots (10 × 10 m; 1.12 ha) were installe

9. Diversity and Guilds of Ants in Different Land-Use Systems in Rio de Janeiro State, Brazil
ABSTRACT This study aimed to evaluate the ant fauna in three different land-use systems: pasture, eucalyptus plantation and secondary forest, in southeastern Brazil. The ant fauna was collected with standardized pitfall traps. Forty-seven ant species were collected, belonging to 24 genera and six subfamilies. The total ant species richness was significantly

10. Environmental structure affects taxonomic diversity but not functional structure of understory birds in the southwestern Brazilian Amazon
RESUMO Mudanças nas características ambientais podem influenciar o uso do habitat por aves, afetando o número de indivíduos, a riqueza de espécies e alterando a composição de espécies e estrutura funcional das assembleias. Medidas que avaliam a estrutura funcional de assembléias biológicas constituem uma ferramenta complementar à abordagem taxonô

12. Dynamics of solar radiation and soybean yield in agroforestry systems
Abstract Soybean (Glycine max L.) monocropping have had a great socio-economic and environmental impact on the world and agroforestry systems has been considered an alternative for more sustainable production. The aim of this study was to evaluate the effect of different arrangements of agroforestry systems of the species E. urophylla x E. grandis and P. dub
