This study is part of the Floristic and Forest Inventory of Santa Catarina, conceived to evaluate forest resources, species composition and structure of forest remnants, providing information to update forest conservation and land use policy in Southern Brazilian State of Santa Catarina (95 000km²). In accordance to the Brazilian National Forest Inventory (IFN-BR), the inventory applies systematic sampling, with 440 clusters containing four crosswise 1 000m² plots (20x50m) each, located on a 10x10km grid overlaid to land use map based on classification of SPOT-4 images from 2005. Within the sample units, all woody individuals of the main stratum (DBH?10cm) are measured and collected (fertile and sterile), if not undoubtedly identified in field. Regeneration stratum (height>1.50m; DBH<10cm) is registered in 100m² in each sample unit. Floristic sampling includes collection of all fertile trees, shrubs and herbs within the sample unit and in its surroundings. This study performs analysis based on 92 clusters measured in 2008 within an area of 32 320km² of mixed ombrophyllous forests with Araucaria angustifolia located at the state’s high plateau (500m to 1 560m above sea level at 26º00’-28º30’ S and 49º13’-51º23’ W). Mean density (DBH?10cm) is 578 individuals/ha (ranging from 85/ha to 1 310/ha), mean species richness in measured remnants is 35 (8 to 62), Shannon and Wiener diversity index (H’) varies between 1.05 and 3.48. Despite high total species diversity (364 Magnoliophyta, five Coniferophyta and one tree fern) and relatively high mean basal area (25.75m²/ha, varying from 3.87 to 68.85m²/ ha), the overwhelming majority of forest fragments are considered highly impacted and impoverished, mostly by logging, burning and extensive cattle farming, turning necessary more efficient protection measures. Basal area was considered an appropriate indicator for stand quality and conservation status.

The burrowing nematode (Radopbolus similis) is considered the most economically important nematode to banana production worldwide. In Brazil, yield losses can reach up to 100 % among Cavendish bananas. Although no information is available on genetic and biological variability of the nematode in Brazil in bananas and other plants, observations have suggested the occurrence of several biotypes of the nematode. The objective of this study was to observe genetic variability of 12 populations of R similis using RAPD markers, in relation to geographic origin and aggressiveness on diploid (AA) and triploid (AAA) banana genotypes. This study showed that all populations of R similis reproduced in all banana genotypes, and higher values for the reproduction factor occurred on Grand Naine, Pisang Jari Buaya, and Yangambi km 5. Differences in aggressiveness were reflected on plant height and root weight. Populations from Bahia (BA1 and BA2), Minas Gerais (MG1 and MG2), Pernambuco (PE), Cuba (CUB), and Costa Rica (CR) were more aggressive on banana plants, in particular those from Pernambuco and Bahia. By contrast, populations from Rio de Janeiro (RJ), São Paulo (SP1 and SP2), Santa Catarina (SC), and Australia (AUS) were less aggressive. Through RAPD markers at the relative genetic distance of 0.45, the populations of R similis were separated in five similarity groups. No correlation between geographic proximity and genetic similarity was observed among R similis populations, except for the populations from Bahia (BA1 and BA2). In this study it was evidenced a close association between the level of aggressiveness on bananas and a short genetic distance, except for the populations from Rio de Janeiro (RJ) and Australia (AUS).
