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 Coarazuphium auleri sp. n. (Carabidae: Zuphiini), a new troglobitic ground-beetle in Central-Western Brazil(2021-12-12) Pellegrini, Thais Giovannini; Bichuette, Maria Elina; Vieira, LetíciaABSTRACT In this paper, we describe Coarazuphium auleri sp. n. Until now, the species occurred in a single limestone cave, located at Nobres municipality (state of Mato Grosso – Central-Western Brazil). The new species comprises an apterous species from the genus Coarazuphium with the complete absence of hindwings, eyes are composed of very reduced eyes-scars, depigmentation and ommatidia are not evident. We also provide an updated key for species identification of Coarazuphium from the most recently published one. We followed the criteria of IUCN and classified the species as Critically Endangered – CR, IUCN criteria B1ab(iii)+2ab(iii), since the species has a restricted geographical distribution; estimated occurrence length <100 km2; population in few locations and with a continued decline in area, extent, and quality of habitat. According to Brazilian law, the existence of a critically endangered species places the Lagoa Azul cave as one of maximum relevance.- Feeding in the dark: are stonefly nymphs good indicators of reference conditions for cave streams? A case study using gut content analysis in Brazilian quartzite caves(2020-02-11) Costa, Bárbara Goulart; Ferreira, Rodrigo Lopes; Pellegrini, Thais GiovanniniBenthic macroinvertebrates are considered important bioindicators of water quality, and their distribution is influenced by several factors, including food availability. This feeding is an essential factor for all living beings and determines aspects of temporal and spatial population dynamics and relations between individuals and their respective habitats. The present work aimed to analyze the diet of nymphs of the order Plecoptera associated with quartzite caves located in southern Minas Gerais state, Brazil. The stomach contents of 79 specimens were analyzed, and many were empty (40.5 %). Among the nymphs with stomach contents, the most frequent content was fine particulate organic matter. The high amount of individuals with empty content may indicate a low tolerance of these organisms to subterranean environments.
