- New data on the fruit flies (Drosophilidae) of Madeira archipelago with notes on the ecology of the endemic Drosophila madeirensis MonclúsPublication . Rego, Carla; Aguiar, António F.; Cravo, Délia; Boieiro, Mário; Silva, Isamberto; Castro, Catarina P.; Menezes, Dilia; Serrano, Artur R. M.The first findings of drosophilids from Desertas and Porto Santo islands (Madeira archipelago) are reported and the knowledge on the abundance and distribution of the endemic Drosophila madeirensis Monclús is updated. This Madeiran endemic was found associated with forest habitats, but was not exclusive of Laurisilva. Furthermore, the finding of widespread populations with moderate abundance indicates that presently this species is not endangered. Finally, we provide an updated checklist of the family Drosophilidae occurring in the Madeira archipelago.
- Spatial distribution of Madeira Island Laurisilva endemic spiders (Arachnida: Araneae)Publication . Crespo, Luís C.; Boieiro, Mário; Cardoso, Pedro; Aguiar, Carlos A. S.; Amorim, Isabel R.; Barrinha, Carla; Borges, Paulo A. V.; Menezes, Dilia; Pereira, Fernando E. A.; Rego, Carla; Ribeiro, Sérvio P.; Silva, Israel F.; Serrano, Artur R. M.Madeira island presents a unique spider diversity with a high number of endemic species, many of which are still poorly known. A recent biodiversity survey on the terrestrial arthropods of the native forest, Laurisilva, provided a large set of standardized samples from various patches throughout the island. Out of the fifty two species recorded, approximately 33.3% are Madeiran endemics, many of which had not been collected since their original description. Two new species to science are reported – Ceratinopsis n. sp. and Theridion n. sp. – and the first records of Poeciloneta variegata (Blackwall, 1841) and Tetragnatha intermedia Kulczynski, 1891 are reported for the first time for Madeira island. Considerations on species richness and abundance from different Laurisilva locations are presented, together with distribution maps for endemic species. These results contribute to a better understanding of spider diversity patterns and endemic species distribution in the native forest of Madeira island.
- Stone-stacking as a looming threat to rock-dwelling biodiversityPublication . Rocha, Ricardo; Borges, Paulo A. V.; Cardoso, Pedro; Kusrini, Mirza D.; Martín-Esquivel, José L.; Menezes, Dilia; Ferreira, Mário Mota; Nunes, Sara F.; Órfão, Inês; Gonçalves, Catarina Serra; Sim-Sim, Manuela; Sepúlveda, Pedro; Teixeira, Dinarte; Traveset, AnnaThis letter to the editor describes the surge of “photo-friendly” stacks of stones as an emerging tourism-associated threat to rock-dwelling biodiversity.
