Brazil opens highly protected caves to mining, risking fauna

Brazil’s government has changed the designation of caves that warrant top priority for conservation (see go.nature.com/3gy5). Constituting some 13–30% of the country’s 22,000 protected caves, these will now be open to commercial exploitation, which could seriously affect their vulnerable fauna.

Hotspot in ferruginous rock may have serious implications in Brazilian conservation policy
(2022-09-01) Zeppelini, Douglas; Oliveira, João Victor L. C.; Lima, Estevam C. Araujo de; Brito, Roniere A.; Ferreira, Aila S.; Stievano, Luis C.; Brito, Nathan P.; Oliveira-Neto, Misael A.; Lopes, Bruna C. H.
A hotspot of subterranean Collembola in ferruginous rock caves and Mesovoid Shallow Substratum is revealed by the analysis of pseudocryptic diversity. The diversity is accessed by detailed description of chaetotaxy and slight variation in morphology of 11 new species of Trogolaphysa Mills, 1938 (Collembola, Paronellidae, Paronellinae) and the 50 previously recorded species of springtails from caves, using optical and electronic microscopy. When combined with recent subterranean surveys, our results show an important reservoir of cave diversity in the Mesovoid Shallow Substratum. Contrastingly the conservation policy for subterranean fauna in metallogenic areas in Brazil prioritizes the caves instead the cave species, which may be extremely detrimental to the fauna in the shallow subterranean habitats not accessible to humans.
