Cave-adapted millipedes from Portugal: species conservation profiles.

Background: Amongst the cave-dwelling millipedes (Diplopoda), there are several endemic species in Portugal with a very small geographical distribution. These species play an important role in the decomposition of organic matter in subterranean ecosystems and are vulnerable to disturbance from human activities, such as habitat destruction, pollution infiltrating from the surface and cave tourism.

New Information: We present the IUCN Red List profiles for cave-adapted millipedes (Diplopoda) from Portugal and propose conservation measures to prevent extinction.

Species conservation profiles of cave-adapted terrestrial isopods from Portugal.

Background: Terrestrial isopods (Oniscidea) are the most diverse group of troglobionts in caves of continental Portugal. They occur in all karst regions of Portugal, play a major role in decomposition of organic matter in caves and may act as umbrella species for the conservation of all other cave-adapted invertebrates.

New Information: We present the IUCN Red List profiles for the cave-adapted terrestrial isopods from continental Portugal, based on recent distribution data from caves.

Cave-adapted beetles from continental Portugal.

Background: The cave biodiversity of continental Portugal faces tremendous conservation challenges, mostly linked to their direct destruction and contamination infiltrating from the surface. Beetles are the most diverse insects and one of the most diverse arthropod groups in caves of Portugal.

New Information: We present the IUCN Red List profiles for the cave-adapted beetles from continental Portugal, all endemic to their respective geological units and massifs.
