- Atelier de moluscos terrestres em Santa Maria : conhecer para protegerPublication . Cunha, Regina Tristão da; Teixeira, Dinarte; Ferreira, Ana; Melo, Paulo Jorge; Rocha, Cátia; Rodrigues, PedroA maioria das acções de educação ambiental empreendidas com as crianças e jovens portugueses visa, tradicionalmente, os resíduos e a água e, mais recentemente, a eficiência energética. As acções educativas que dão a conhecer os valores da biodiversidade, à escala regional ou local, são menos frequentes, e poucas têm um carácter prático e/ou experimental, pelo que a maioria das pessoas, mesmo se empenhada em proteger e conservar “as suas” espécies e ecossistemas, desconhece o que pode fazer. Assim, dar a conhecer as espécies da fauna e da flora, nomeadamente, aquelas que são raras ou endémicas, e os habitats que as suportam, poderá ser um factor decisivo para proteger e conservar a biodiversidade de uma determinada região ou localidade. É neste contexto que, no âmbito da Expedição Científica Santa Maria/2009, surge o projecto “Atelier de Moluscos Terrestres”, com os seguintes objectivos: dar a conhecer a diversidade malacológica da ilha de Santa Maria e estimular a adopção de medidas integradas de conservação e protecção das espécies e dos seus habitats.
- Mid-Atlantic Islands Invertebrate Specialist Group, Newsletter n.º 7Publication . Wilkins, Vicky; Borges, Paulo A. V.; Teixeira, DinarteIn this issue, Luís Crespo presents the recent taxonomic revision of the Hognas from Madeira archipelago. Mário Boieiro and Paulo Borges share the new findings of introduced species in the Azores. At the same time, António Franquinho Aguiar brings the new paper of J. Claessens et al. regarding the pollination strategy of the Gennaria diphylla on the Canary and Madeira Islands. Carla Rego et al. talk about the hoverflies from the Madeira archipelago, while Yeray Monasterio informs about the butterflies observation workshops which will take place at La Palma Island (Canaries Islands). Dinarte Teixeira, Marco Neiber and Klaus Groh signal the start of a conservation project in Tenerife addressing five Critically Endangered endemic land snails.
- Mid-Atlantic Islands Invertebrate Specialist Group, Newsletter n.º 8Publication . Wilkins, Vicky; Borges, Paulo A. V.; Teixeira, DinarteIn this issue, Vicky Wilkins brings us news about the restoration and protection of the cloud forests of St. Helena (UK) and its impact on the island invertebrate endemics. In addition, Vicky shares news about the re-exploration of the endemic subterranean fauna at Ascension Island (UK), its methods and challenges. In this number, we dedicate special attention to the work presented by group members at the World Congress of Malacology, which took place in Munich in August. Martina Panisi talked about the discovery and preservation of the endemic-rich malacofauna of the Gulf of Guinea oceanic islands (central Africa). Next, Marco Neiber spoke about the origin, radiation and diversification of Hemicycla land snails in the Canary Islands, while Klaus Groh talked about the Pomatiidae of the Central Canary Islands. Finally, Dinarte Teixeira spoke about the conservation of the land snails in Oceanic islands.
- 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.
- Using taxonomically unbiased criteria to prioritize resource allocation for oceanic island species conservationPublication . Martín, José L.; Cardoso, Pedro; Arechavaleta, Manuel; Borges, Paulo A. V.; Faria, Bernardo F.; Abreu, Cristina; Aguiar, António F.; Carvalho, José A.; Costa, Ana C.; Cunha, Regina Tristão da; Fernandes, Francisco M.; Gabriel, Rosalina; Jardim, Roberto; Lobo, Carlos; Martins, António M. de Frias; Oliveira, Paulo; Rodrigues, Pedro; Silva, Luís; Teixeira, Dinarte; Amorim, Isabel R.; Homem, Nídia; Martins, Berta; Martins, Mónica; Pereira, EnésimaOceanic islands have been the grand stage of documented extinctions. In view of limited resources, efficient prioritization is crucial to avoid the extinction of taxa. This work lists the top 100 management priority species for the European archipelagos of the Macaronesian region (Azores, Madeira and the Canary Islands), taking into account both their protection priority and their management feasibility. Bryophytes, vascular plants, molluscs, arthropods and vertebrates were scored by species experts following two sets of criteria: (i) protection priority, including ecological value, singularity, public institutions’ management responsibilities and social value; (ii) management feasibility, including threats knowledge and control feasibility, external socio-economical support for management and biological recovery potential. Environmental managers weighted the same criteria according to their management importance. Final species scores were determined by the combination of both species valuation and criteria weighting. Vascular plants dominate the Top 100 list, followed by arthropods and vertebrates. The majority of listed taxa are endemic to one archipelago or even to a single island. The management feasibility criteria did not dictate that all taxa must be eminently endangered, as for most of the species it should be relatively easy to control threats. The main advantages of this process are the independent participation of scientists and conservation managers, the inclusion of criteria on both protection priority and management feasibility and the taxonomically unbiased nature of the process. This study provides a potentially useful biodiversity conservation tool for the Macaronesian archipelagos that could be readily implemented by the respective regional governments in future legislation.
