A new arbuscular mycorrhizal fungus, Cetraspora helvetica, was found in three Swiss agricultural soils: a no-till crop production system and two temporary grasslands. It forms white spores, 210?270 µm diam, on dark yellow sporogenous cells. The spores have three walls: a triple-layered outer, a bi-layered middle and a triple-layered inner wall. The spore surface is crowded with convex warts, 5?12 µm diam at the base and 1.5?5.0 µm high. The germination shield is hyaline with multiple (6?10) lobes. Glomerospores of two other Gigasporineae spp. have also three walls, multiple-lobed hyaline germination shields, and projections on the outer spore surface: C. spinosissima and C. striata. However, spores of these fungi are substantially pigmented (ochraceous yellow to rust) and crowded with short, thin spines or fingerprint-like processes, respectively. Partial sequences of the 28S ribosomal gene place the new species adjacent to C. spinosissima, C. pellucida, and C. gilmorei. Phylogenetic analyses demonstrate the monophyly of the two genera Racocetra and Cetraspora within the Racocetraceae. |

Abstract The Conservation Units (CU) were created to protect natural environments from growing degradation and to impede the expansion of urbanization and agricultural crops. The Serra da Canastra National Park, established to protect the headwaters of the São Francisco River and other places of scenic and ecological interest, is extensively visited due to its many tourist attractions, such as waterfalls, fauna and flora. An analysis of the park?s geography is needed to assess the risk involved in and its suitability for public use due to its territorial extension and environmental complexities. Thus, this study aimed to investigate the background of issues of interest to CU management. Additionally, we used high-resolution RapidEye imagery, altimetry and database of park infrastructure to build geospatial database and estimate classes of suitability for and risk in public use through GIS tools. The resulting cartographic data can support the planning of policies concerning the landscape and park?s territorial management. |
