13. Riparian forest fragments in rice fields under different management: differences on hymenopteran parasitoids diversity
Resumo Os himenópteros parasitoides são importantes agentes de controle biológico em agroecossistemas com sua diversidade variando de acordo com a heterogeneidade de habitat. Nesse sentido, o objetivo deste trabalho foi avaliar a influência da distância de áreas com fragmentos de vegetação natural das áreas de cultivo de arroz, o tipo de manejo (org

14. Vegetative Propagation of Brazilian Native Species for Restoration of Degraded Areas
ABSTRACT Vegetative propagation by live cuttings is an alternative to reproduce native plants with the potential to be used in restoration of riparian forests and degraded areas. This propagation capacity is intrinsic to each species and is influenced by several factors, particularly the time of the year when cuttings are collected. The aim of this work was

15. Riparian vegetation structure and soil variables in Pandeiros river, Brazil
Resumo Este estudo analisou as variações florísticas, estruturais e suas relações com variáveis do solo em dois trechos de vegetação ripária em uma região ecotonal entre savana e zonas semi-áridas. Propomos a hipótese de que, apesar da proximidade entre as áreas amostradas, as condições do solo são distintas e levam a mudanças na estrutura e

17. Landscape Ecology in a Watershed of the Ocoy River, Western Parana State, Brazil
ABSTRACT This study evaluated the landscape structure of a watershed located in a region considered strategic for the implementation of the Paraná River Biodiversity Corridor. Based on land-use/land-cover mapping, four different scenarios were generated: 1) real situation, 2) considering the edge effect, 3) without Permanent Preservation Areas (APPs), and

18. Tecnologia Blockchain: inovação em Pagamentos por Serviços Ambientais
RESUMO Os problemas socioecológicos são complexos e multidimensionais, envolvendo pelo menos a dimensão ambiental, social, econômica, política e institucional. Os problemas relacionados ao uso múltiplo dos recursos hídricos, a revitalização de bacias hidrográficas e a recuperação de rios urbanos têm colocado novos desafios para a sociedade, os q

19. Herpetofauna of Parque Estadual Altamiro de Moura Pacheco: one of the last remnants of seasonal forest in the core region of the Brazilian Cerrado
ABSTRACT Studies in remnants of semi-deciduous seasonal forest of the Cerrado are needed to fill sampling gaps and improve basic knowledge of biodiversity. This study presents data on the herpetofauna of Parque Estadual Altamiro de Moura Pacheco, one of the last protected areas of seasonal forest in the core region of the Brazilian Cerrado. Fourteen sites we

20. Vegetative and Environmental Components in a Secondary Riparian Forest in the Southern Plateau of Santa Catarina, Brazil
ABSTRACT This study investigated the vegetation and environmental variable of fragments at different successional stages in a secondary riparian forest in the municipality of Ponte Alta, Santa Catarina state, Brazil (27°29’00” S and 50°17’11” W, WGS84), aiming to list priority variables for monitoring forest succession in riparian forests. For thi

21. Responses of riffle beetle assemblages to deforestation in a semi-deciduous Atlantic Forest remnant
Abstract Deforestation affects freshwater assemblages since aquatic organisms are dependent on the structure of the riparian vegetation. To investigate the responses of riffle beetles (Elmidae) to deforestation, this study assessed the structure of riffle beetle assemblages found in streams running through a large and well-preserved semi-deciduous Atlantic F

22. Effect of vegetation on cutaneous leishmaniasis in Paraná, Brazil
BACKGROUND Cutaneous leishmaniasis (CL) is endemic in the state of Paraná, Brazil. OBJECTIVE This study aimed at analysing the influence of the remaining native vegetation on the prevalence of CL in Paraná. METHODS Global testing was used for spatial autocorrelation along with simultaneous autoregressive model (SAR). The regression was based on the C

23. Does the landscape surrounding streams affect the occurrence of freshwater crabs? A case study of the genus Aegla (Crustacea: Decapoda: Anomura) in subtropical basins
ABSTRACT Changes in the landscape where watersheds are located may affect the stream biota in different ways. In order to explore this idea, we collected freshwater crabs of the genus Aegla Leach, 1820 in subtropical region of southern Brazil. We also measured a number of landscape features and physico-chemical variables in the collection streams and surroun

24. Contamination and Soil Biological Properties in the Serra Pelada Mine - Amazonia, Brazil
ABSTRACT Discovered in 1980 and unleashed an utter gold rush of the modern era, Serra Pelada was the largest open-air mine in Brazil. About 80,000 gold prospectors worked there until 1984, when the gold pits were flooded. The environmental impact caused by mining inflicted irreversible damage to the ecosystem, with the formation of a large lake and piles of
