Item Biodiversidade Em Seis Cavernas No Parque Estadual Do Sumidouro (Lagoa Santa, MG)(Revista Brasileira de Espeleologia, 2012) Iniesta, Luiz Felipe Moretti; Ázara, Ludson Neves; Silva, Marconi Souza; Ferreira, Rodrigo Lopes- Cave lithology effect on subterranean biodiversity: A case study in quartzite and granitoid caves(2020-10) Souza-Silva, Marconi; Iniesta, Luiz Felipe Moretti; Ferreira, Rodrigo LopesPhysical features and lithology variations contribute to promoting changes in faunal composition and richness between caves in Neotropics. Cave lithology effects on biodiversity were reported to iron ore caves in Brazil, however, it is less clear to granitoid and quartzite caves. Hence, based on these two kinds of rocks we correlate invertebrates species richness and composition with some cave features (lithology, the distance between caves, cave extension, number of entrances, entrance size, environmental stability, and altitude). Overall, 1,027 invertebrate species were recorded in 50 sampled caves. From this total, 11 obligate cave species were found. Invertebrate assemblages showed considerable turnover between caves and rock types with a strong contribution of replacement component of beta diversity. Replacement influence was greatest in quartzite caves mainly because of altitude and distance among caves. Furthermore, richness was determined by cave extension in both lithotypes, although this relationship was much more pronounced for the granitoid caves, which contradicts previous studies. The granitoid caves studied here are predominantly structured by stacked blocks with macro and meso anastomosed subterranean spaces that provide an extensive network of interstices with structural characteristics similar to shallow subterranean habitats that may increase in habitat availability and species richness. The study highlight that the lithology-mediated effects of cave extension on richness must be considered for quartzite and granitoid in the ecological and conservational proposal. Furthermore, altitude and distance among caves were important elements determining invertebrate composition.
Item Expanding the range of the troglobitic millipede Pseudonannolene ambuatinga Iniesta & Ferreira, 2013: insights into its distribution and conservation status (Spirostreptida, Pseudonannolenidae)(2024-06-10) Iniesta, Luiz Felipe Moretti ; Oliveira, Marcus Paulo ; Brescovit, Antonio ; Bouzan, Rodrigo SalvadorPseudonannolene Silvestri, 1895 (Spirostreptida, Pseudonannolenidae) is one of the most common genera of millipedes in Brazilian caves. To date, only three troglobitic species are known in a list of 56 species described for the genus. In this study, we report new records of the cave-dwelling species Pseudonannolene ambuatinga Iniesta & Ferreira, 2013 in Minas Gerais state. These records extend its distribution by approximately 600 km2, making it the most widely distributed cave-dwelling millipede in the country. We also provide a new assessment of its conservation status based on the records and threats to its populations.Item New species of Pseudonannolene Silvestri, 1895 from Brazilian limestone caves with comments on the potential distribution of the genus in South America (Spirostreptida: Pseudonannolenidae)(Zootaxa, 2014) Iniesta, Luiz Felipe Moretti; Ferreira, Rodrigo LopesItem The first troglobitic Glomeridesmus from Brazil, and a template for a modern taxonomic description of Glomeridesmida Diplopoda(Zootaxa, 2012) Iniesta, Luiz Felipe Moretti; Ferreira, Rodrigo Lopes; Wesener, Thomas
