Item Ácaros cavernícolas do Brasil: uma observação preliminar sobre a ocorrência e distribuição das famílias(Mundos Subterráneos, 2009) Bernardi, Leopoldo Ferreira de Oliveira; Zacarias, Maurício Sergio; Silva, Marconi Souza; Ferreira, Rodrigo LopesItem Amphibious Shelter-Builder Oniscidea Species from the New World with Description of a New Subfamily, a New Genus and a New Species from Brazilian Cave (Isopoda, Synocheta, Styloniscidae)(Plos One, 2015) Souza, Leila A.; Ferreira, Rodrigo Lopes; Senna, André R.Item An Exceptionally High Bat Species Richness in a Cave Conservation Hotspot in Central Brazil(2021-07-09) Barros, Jennifer de Sousa; Bernard, Enrico; Ferreira, Rodrigo LopesCaves are among the most used and important roosts for hundreds of bat species worldwide. However, caves remain some of the least known and most threatened environments globally. Documenting the richness of bat species in caves is important not only to draw attention to the uniqueness and relevance of these roosts, but it also contributes to the identification of priority sites for the conservation of bats and the cave fauna dependent upon them. Here, we assessed and described an exceptionally high bat richness in a group of caves in southeastern Tocantins, central Brazil. Inventories carried out in 19 caves resulted in seven families and 31 bat species, of which three were new regional records. Twelve caves were used by threatened and endangered bat species, eight had high diversity indices, and seven caves had high species richness, including one cave that may hold a world record with 26 bat species found inside. The variation in beta diversity is mainly due to species turnover, which indicates that protecting the largest possible number of caves would be ideal for the most efficient conservation of local bat assemblages. The sampled region stands out for its high potential for the conservation of endangered species, and we strongly recommend the full protection of 15 caves classified as a priority for conservation.Item An exceptionally high bat species richness in a cave conservation hotspot in Central Brazil(2021-06) Ferreira, Rodrigo Lopes; de Sousa Barros, Jennifer; Bernard, EnricoCaves are among the most used and important roosts for hundreds of bat species worldwide.

Item Asymmetry compensation in a small vampire bat population in a cave: a case study in Brazil(Subterranean Biology, 2015) Ueti, Amanda; Pompeu, Paulo Santos; Ferreira, Rodrigo LopesItem Before it’s too late: priority areas for conservation of cryptic and threatened species of troglobitic arthropods in the Brazilian semiarid(2024-04-18) Bento, Diego de Medeiros; Ferreira, Rodrigo Lopes; Vasconcelos, Santelmo; Lima, Jamily Lorena Ramos de; Oliveira, Guilherme; Silva, Tiago Castro; Lima, Sergio Maia QueirozOne of the most important steps in identifying priority areas for conservation is the assessment of species richness and their extinction risks. While most species remain undescribed, the identification of cryptic lineages is frequent in phylogenetic and phylogeographic studies. This is particularly common in troglobites, exclusively subterranean organisms. The Jandaíra Formation, in the Brazilian semiarid, combines the occurrence of extensive karstic areas with hundreds of caves and subterranean aquifers in a region with intense paleoclimatic changes. This region is recognized for the richness of troglobitic species, some of which are widely distributed in heterogeneous areas. This suggests cryptic lineages that can be differentially exposed to anthropogenic threats, with distinct extinction risks regarding the nominal taxa of which they putatively belong. To test it, a large sampling was conducted and, by means of lineage delimitation analyses, the genetic structure of four troglobitic taxa, three aquatic and one terrestrial, was evaluated. In addition, the extinction risk of these lineages was assessed and priority areas for conservation were identified. The results indicated that while Cirolanidae sp. 1 (Isopoda) is a single species widely distributed, Cirolanidae sp. 2, Potiberaba porakuara (Amphipoda) and Kinnapotiguara troglobia (Hemiptera) present an extensive diversity of cryptic and endemic lineages, most of which are likely new threatened species. Furthermore, two priority areas for conservation of these lineages were identified. Thus, comparative phylogeography may represent a first step in the conservation of subterranean taxa, indicating areas that should be prioritized in a context of increasing threats and dwindling conservation resources.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 LopesItem Brasileirinidae, a new isopod family (Crustacea: Isopoda) from the cave in Bahia (Brazil) with a discussion on its taxonomic position(Zootaxa, 2012-07) Ferreira, Rodrigo Lopes; Prevorcnik, Simona; Sket, BorisItem Brasilomma gen. nov., a new prodidomid genus from Brazil (Araneae, Prodidomidae)(Zootaxa, 2012-10) Ferreira, Rodrigo Lopes; Silva, Marconi Souza; Brescovit, Antonio Domingos; Rheims, Cristina Annetaxonomia- Caracterização dos ecossistemas das Grutas Aroê Jari, Kiogo Brado e Lago Azul(Chapada dos Guimarães, MT): subsídios para o turismo nestas cavidades(Revista de Biologia e Ciências da Terra, 2009) Ferreira, Rodrigo Lopes; Bernardi, Leopoldo Ferreira Oliveira; Silva, Marconi Souza

Item Cave lithology determining the structure of the invertebrate communities in the Brazilian Atlantic Rain Forest(Biodiversity and Conservation, 2011) Ferreira, Rodrigo Lopes; Silva, Marconi Souza; Martins, Rogério Parentoni- 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 Cave lithology influencing EPT (Ephemeroptera, Plecoptera, Trichoptera) assemblages and habitat structure in south-eastern Brazil(2021-06-18) Pacheco, Gabrielle Soares Muniz; Pellegrini, Thais Giovannini; Ferreira, Rodrigo LopesKnowing how cave lithology influences the benthic macroinvertebrate fauna is important for conservation and management of subterranean aquatic systems. However, those influences are still poorly understood, especially in the Neotropics. This study aimed to understand how cave lithology can influence benthic EPT assemblages by assessing the differences in the EPT genera structure in caves of two distinct lithologies (quartzite and limestone) and determining possible differences in the lithology habitats. To achieve this, hydrochemistry data and biological samples were collected in six allogenic cave streams from the two aforementioned lithologies. Results showed that both the assemblages from different lithologies and within the same lithology are statistically different, thus indicating probable regional influences beyond local ones. Our results also pointed out an effect of lithology on the substrate parameters, which in turn affected the EPT composition. Cave lithology affects water chemical and physical characteristics, thus supporting different EPT assemblages. The results of this study provide a foundation for future investigation on how the lithology can influence the benthic macroinvertebrate fauna and should lead to means of predicting such fauna on the basis of the cave lithology and water chemistryItem Cavernas em risco de extinção(Ciência Hoje, 2001) Ferreira, Rodrigo Lopes; Martins, Rogério Parentoni
