- Insights from the Dalberto Teixeira Pombo (DTP) Arthropod Collection – II. Long-term monitoring of arthropod fauna in the show cave Algar do Carvão (Terceira, Azores, Portugal)Publication . Fonseca Crespo, Luís Carlos; Amorim do Rosário, Isabel; Pereira, Fernando; Borges, P.A.V.; Ruzzier, EnricoABSTRACT: The second manuscript in the series "Dalberto Teixeira Pombo (DTP) Arthropod Collection" focuses on Algar do Carvão, a remarkable volcanic pit on Terceira Island, Azores, that is a Natural Monument, a show cave and part of the Terceira Island Natural Park. This volcanic cave is unique amongst the archipelago’s subterranean systems due to its distinctive geological features, including rare silica-based speleothems and its exceptional natural setting. Surrounded by remnants of native laurel forest, the cave hosts a specialised assemblage of arthropods, including several taxa endemic to the Azores and single island endemic species. Of particular interest are four obligate cave-dwelling species or subspecies (troglobionts): the centipede Lithobius obscurus azoreae Eason & Ashmole, 1992 (Chilopoda, Lithobiomorpha, Lithobiidae); the springtail Pseudosinella ashmoleorum da Gama, 1988 (Collembola, Entomobryomorpha, Entomobryidae); the spider Turinyphia cavernicola Wunderlich, 2008 (Arachnida, Araneae, Linyphiidae); and the ground beetle Trechus terceiranus Machado, 1988 (Insecta, Coleoptera, Carabidae), the last two being endemics to Terceira Island. These species are part of a fragile and narrowly distributed subterranean fauna shaped by the volcanic origin of the island and its isolation (0.4 Ma). Their presence highlights the conservation value of Algar do Carvão, which serves not only as a cave biodiversity hotspot, but also as a natural laboratory for studying evolution, adaptation to subterranean habitats and island biogeography. Despite being a show cave with frequent human visits, Algar do Carvão retains a relatively intact hypogean ecosystem, though it remains vulnerable to anthropogenic pressures, such as habitat disturbance and pollution.
- Dataset on bryophyte species distribution across an elevational gradient on Flores IslandPublication . Gabriel, Rosalina; Nunes Morgado, Leila; Poponessi, Silvia; Henriques, Debora; Coelho, Márcia; Silveira, Gabriela; Pereira, Fernando; Borges, P.A.V.; Guerrero-Ramírez, NathalyABSTRACT: A bryophyte diversity survey was carried out from July 29 to 1 August 2013, in Santa Cruz das Flores, Flores Island (Azores) (39.471185 N Latitude; -31.184692 W Longitude), along an elevational gradient (70, 200, 400, 600 and 800 m a.s.l.). The study employed the Global Island Monitoring Scheme (GIMS) protocol for bryophytes. At each elevation level, three replicates of six substrates colonised by bryophytes (rock, soil, humus, dead wood, tree trunks, leaves) were collected. In total, 385 sampling events generated 1345 species occurrence records, representing 89 bryophyte species (37 mosses; 52 liverworts).
