Item Ticks (Ixodida) associated with bats (Chiroptera): an updated list with new records for Brazil(2023-08-19) Lourenço, Elizabete Captivo; Famadas, Kátia Maria; Gomes, Luiz Antonio Costa; Bergallo, Helena GodoyBats harbor diverse groups of ectoparasites, such as insects and mites like ticks (Ixodida). Some species of ticks with records for bats and humans have already been reported with the occurrence of pathogens. This research article aims to document new geographical and host records of ticks infesting bats in Rio de Janeiro state, Southeastern Brazil, and provides a list of tick species associated with bats in Brazil. We counted 12 argasid ticks and five ixodid ticks associated with six individuals of bats. Larvae of Amblyomma sp., Ixodes sp., Ornithodoros sp., and Ornithodoros hasei and one nymph of Amblyomma sculptum parasitizing Artibeus obscurus, Phyllostomus hastatus, Micronycteris sp., Molossus fluminensis, and Carollia perspicillata in different localities of Rio de Janeiro state were studied. We carried out a systematic review with the descriptors: tick bat Brazil. We considered data from 42 articles in the systematic review. We compiled eleven records of Ixodidae, and 160 records of Argasidae. Ornithodoros cavernicolous were the most recorded tick species. Overall, we registered 171 tick–bat or roost–bat associations with 85 records of these infesting bats. The review also shows the occurrence of tick species associated with bats, and we present new records on ticks parasitizing bats in Brazil.Item Bat species diversity from Reserva Ecológica de Guapiaçu, Rio de Janeiro, Brazil: a compilation of two decades of sampling(2023-11-25) Pires, Rayssa S.A.; Soares, Gabriella; Souza, Renan F.; Teixeira, Tiago S.M.; Monteiro-Alves, Priscila S.; Lourenço, Elizabete C.; Bergallo, Helena G.; Costa, Luciana M.; Santori, Ricardo T.; Esbérard, Carlos E.L.; Moratelli, Ricardo; Novaes, Roberto L.M.Reserva Ecológica de Guapiaçu (REGUA) is a private, protected area inside a remnant of the Atlantic Forest with high biodiversity. Although the bats of the reserve have been sampled for more than two decades, few studies have been published about them. Based on a compilation of data from several surveys, we present an updated list of the bat species there and compare it with surveys from other locations in the Atlantic Forest. From August 1998 to September 2021, at least 194 sampling nights were carried out at REGUA by different research groups from various institutions, totaling 448,092 m2.h of sampling. A total of 4,069 individuals were captured, belonging to 47 species and six families. Additionally, our results indicate that it is possible that some species that occur at REGUA have not been recorded yet. REGUA has the greatest num ber of bat species known for the Atlantic Forest. This most likely results from the fact that the reserve includes large areas of mature, continuous forest connected with other protected areas in the State of Rio de Janeiro. Another factor contributing to the high diversity of bat species at REGUA is that the area has been intensely sampled for many years. Given that the bat assemblage there appears to be a good proxy to ascertain the ecological patterns of biodiversity in well-preserved forests, we consider REGUA to be an important area for long-term ecological research. The basic knowledge about the ecological interactions of bats with different food resources and zoonotic microorganisms offers a unique opportunity to carry out research in several areas of knowledge, making it possible to address questions about bat assemblage structure, bat-parasite ecology, competition, niche partitioning, and other related studies.Item Enhancing the still scattered knowledge on the taxonomic diversity of freshwater triclads (Platyhelminthes: Dugesiidae) in caves from two Brazilian Biomes(2020-11-18) Hellmann, Lindsey; Lopes Ferreira, Rodrigo; Rabelo, Lucas; Leal-Zanchet, Ana MariaRecent studies have recorded new species of freshwater planarians in caves of the biomes Amazonia, Atlantic Forest, Cerrado, and Caatinga. Herein we contribute to enhancing this knowledge by describing three new cave-dwelling species of Girardia from three different cave systems situated in two biomes (Atlantic Forest and Cerrado) in eastern Brazil. Girardia spelaea sp. n., from a limestone cave, is eyeless and shows a whitish body. The other two species, G. asymmetrica sp. n. and G. ibitipoca sp. n., from limestone and quartzite caves, show pigmented bodies and eyes. The three species are characterized by dorsal and/or dorsoventral testes and a bulbar cavity with forked ental portions, varying from round or ovoid to elongate. Each new species is easily recognized by a unique combination of characters of their external morphology and reproductive system. Girardia spelaea is probably a troglobitic species and the two other species may be trogrophiles, all of them with a restricted known distribution.
