Item Change in the composition of cave-dwelling bats after a 53-year interval at the Gruta do Limoeiro (Espírito Santo, Brazil)(2022-11-23) Ditchfield, Albert David; Hoppe, João Paulo Maires; Andrade, Gabriella Marchezi; Tahara, Arthur Setsuo; Martins, Felipe de Melo; Scabello, Mirela; Oprea, Monik; Coutinho, Rafael Zerbini; Pimenta, Vinícius Teixeira; Vieira, Thiago BernardiAn especially interesting question is “How many species of bats can be found simultaneously in the same cave?” This information is surprisingly rare in the literature, mainly in the Neotropics. The aim of this study was to sample bats in Gruta do Limoeiro cave, Municipality of Castelo, State of Espírito Santo, Brazil after a 53-year interval of the first survey, by the naturalist Augusto Ruschi. Four surveys were conducted in 2005 and 2006, capturing bats with mist-nets and actively exploring the cave. We recorded eleven species of three families, Phyllostomidae, Vespertilionidae and Molossidae, making Gruta do Limoeiro cave one of the most diverse caves in the World for bats. Of the 14 species found by Ruschi, seven were still present, and four species were added. The seven species lost from Ruschi’s list are mainly Emballonuridae and some Phyllostomidae, probably due to landscape changes. We recommend the long-term monitoring of the Gruta do Limoeiro cave to understand the loss in diversity, and consequently in ecosystem services.Item Persisting while changing over time: modelling the historical biogeographic of cave crickets (Orthoptera, Grylloidea) in Neotropics(2023) Castro-Souza, Rodrigo Antônio; Sobral-Souza, Thadeu; Rabelo, Lucas Mendes; Zefa, Edison; Ferreira, Rodrigo LopesUsing species distribution modelling (SDMs) techniques, we predicted the biogeographic history of crickets commonly found in Neotropical caves as a way to detect potential long-term environmental refuges in South America. Our models were built based on a thorough investigation of existing database regarding the genus Endecous Saussure, 1878 (Ensifera: Phalangopsidae) occurrences. The predictions of their distribution were obtained for two paleoclimate scenarios (LGM — 21 ka and Mid-Holocene — 6 ka), the current climate scenario (0 ka) and one future global warming climate scenario (RCP8.5, 2080–2100). Our findings suggest that in the past, the potential distribution of the crickets was wider, with potential forest corridors connecting different karst areas with caves within their occupancy area. The future prediction indicates a drastic reduction in their spatial distribution with an increased potential for isolation in subterranean ecosystems. Atlantic humid forest patches and caves represent the main environmental refuges for these crickets. Considering the ongoing impacts on surface environments and future climate change, the conservation of caves and karst landscapes has become one of the main strategies for the maintenance of these crickets and all the correlated subterranean communities.
