In caves, the absence of natural light in deeper regions starkly contrasts with the entrance areas, which still exhibit a light gradient extending into the cave interior. This interplay with the structural gradient of the environment potentially exerts distinct influences on invertebrate communities residing in different cave light zones. To invest...

We present the description and illustration of a new species within the genus Charinus Simon, 1892, discovered in a cave located in the state of Tocantins, situated in the northern region of Brazil. Charinus tocantinensis sp. nov., can be distinguished from its congeners by the following combination of distinctive characters: pedipalp femur with fo...

In this study, we used a multimodal statistical approach to assess the influence of physical, trophic, and shelter components on the spatial and temporal structuring of terrestrial invertebrate communities in limestone caves located in Iuiú and Malhada, southwestern Bahia. Seven caves were sampled during two distinct events, in 2016 and 2021, both...

This study describes a new species of the genus Charinus Simon, 1892, found in a cave in the municipality of Natividade, Tocantins, Brazil. The new species differs from other species of the genus by the number of dorsal and ventral spines on the pedipalp femur, by the presence of well-developed medial eyes, by the ocular tubercle, and the shape of...

The theory of habitat heterogeneity, which treats one of the global drivers of biodiversity, is valid for several taxonomic groups and distinct ecosystems, including subterranean environments. However, knowledge about the factors that influence the structure of subterranean communities remains limited, especially in Neotropical regions. We sought t...

Avaliamos as diferenças na riqueza e suficiência amostral de espécies troglóbias e não-troglóbias em resposta às variações da extensão de 29 cavernas, localizadas no estado de Minas Gerais, Brasil. A amostragem de invertebrados se deu por meio de coleta ativa ao longo de toda a extensão acessível da caverna. A localização dos espécimes coletados e...

Caves are peculiar subterranean environments, characterized by the absence of light, high climatic stability (humidity and temperature) and oligotrophy. They occur mainly in rocks of great economic interest, which brings diverse threats to the cave communities. Understanding the structural factors of these communities, then becomes fundamental for...
