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 Proposal for a Geobiodiversity Index Applied to the Morphoclimatic Domain of Cerrado—Brazil(2021-06-30) Valdir Adilson SteinkeThe Morphoclimatic Domain of Cerrado is located in the Brazilian territory, and it is a central area of great importance for the ecological scenario of Brazil. This area has undergone strong anthropic pressure in the last 60 years, especially due to the expansion of agribusiness—a warning sign for the conservation of its natural resources. Studies on geodiversity and biodiversity have sought to contribute with data for maintaining the landscapes of this region. The objective of this proposal is the generation of a geobiodiversity index capable of indicating the most relevant areas of geological, geomorphological, and vegetation aspects to be preserved and conserved within existing legal instruments. The methodological procedures were centered on segmenting the area in 2.472 hexagonal cells, which were subjected to a spatial matrix analysis in GIS and geostatistical environments capable of articulating the various elements and generating an agglutinating index for each cell. The result indicates 276 areas with the highest index value, presenting, therefore, possible classified areas. This index is an attempt to draw attention to Cerrado and the importance of its 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.
