- Flora marina de las islas Salvajes : resultados preliminares de la campaña "Macaronesia 2000".Publication . Parente, Manuela I.; Gil-Rodríguez, María C.; Haroun, Ricardo J.; Neto, Ana I.; De Smedt, G.; Hernández-González, C. L.; Berecibar Zugasti, EstibalizSe relacionan las macroalgas (173 táxones) identificadas hasta el momento, como resultado de las recolecciones realizadas durante la expeditión científica MACARONESIA 2000 en el intermareal y submareal de las Ilhas Selvagens (mayo de 1999). Se citan por vez primera para estas costas 66 táxones, de ellos 53 corresponden a especies y 13 géneros. Desde el punto de vista ficogeográfico se amplía el rango de distribución de numeorsas especies. Las nuevas citas contribuyen principalmente a incrementar el número de táxones con patrones de distribución macaronésica y anfiatlántica. En este sentido, se confirma lo expuesto por Prud'homme van Reine & van den Hoek (1990) para sustentar y considerar la flora marina bentónica de los archipiélagos de Salvages, Madeira y Canarias, con características similares, desinándolos por ello como un grupo de archipiélagos que conforman la Macaronesia s.s.
- Macaronesia as a Fruitful Arena for Ecology, Evolution, and Conservation BiologyPublication . Florencio, Margarita; Patiño, Jairo; Nogué, Sandra; Traveset, Anna; Borges, Paulo A. V.; Schaefer, Hanno; Amorim, Isabel R.; Arnedo, Miquel A.; Ávila, Sérgio P.; Cardoso, Pedro; Nascimento, Lea; Fernández-Palacios, José María; Gabriel, Sofia I.; Gil, Artur José Freire; Gonçalves, Vitor; Haroun, Ricardo J.; Illera, Juan Carlos; López-Darias, Marta; Martínez, Alejandro; Martins, Gustavo M.; Neto, Ana I.; Nogales, Manuel; Oromí, Pedro; Rando, Juan Carlos; Raposeiro, Pedro M.; Rigal, François; Romeiras, Maria M.; Silva, Luís; Valido, Alfredo; Vanderpoorten, Alain; Vasconcelos, Raquel; Santos, Ana M. C.Research in Macaronesia has led to substantial advances in ecology, evolution and conservation biology. We review the scientific developments achieved in this region, and outline promising research avenues enhancing conservation. Some of these discoveries indicate that the Macaronesian flora and fauna are composed of rather young lineages, not Tertiary relicts, predominantly of European origin. Macaronesia also seems to be an important source region for back-colonisation of continental fringe regions on both sides of the Atlantic. This group of archipelagos (Azores, Madeira, Selvagens, Canary Islands, and Cabo Verde) has been crucial to learn about the particularities of macroecological patterns and interaction networks on islands, providing evidence for the development of the General Dynamic Model of oceanic island biogeography and subsequent updates. However, in addition to exceptionally high richness of endemic species, Macaronesia is also home to a growing number of threatened species, along with invasive alien plants and animals. Several innovative conservation and management actions are in place to protect its biodiversity from these and other drivers of global change. The Macaronesian Islands are a well-suited field of study for island ecology and evolution research, mostly due to its special geological layout with 40 islands grouped within five archipelagos differing in geological age, climate and isolation. A large amount of data is now available for several groups of organisms on and around many of these islands. However, continued efforts should be made toward compiling new information on their biodiversity, to pursue various fruitful research avenues and develop appropriate conservation management tools.
- Mapping and assessing ecosystem services in Europe's Overseas : A comparative analysis of MOVE case studiesPublication . Sieber, Ina M.; Montero-Hidalgo, Miriam; Kato-Huerta, Jarumi; Rendon, Paula; Santos-Martín, Fernando; Geneletti, Davide; Gil, Artur José Freire; Trégarot, Ewan; Lagabrielle, Erwann; Parelho, Carolina Paula Furtado de Medeiros; Arbelo, Manuel; van Beukering, Pieter; Bayley, Dan; Casas, Enrique; Duijndam, Sem; Cillaurren, Esperance; David, Gilbert; Dourdain, Aurélie; Haroun, Ricardo J.; Maréchal, Jean-Philippe; Martín García, Laura; Otero-Ferrer, Francisco; Palacios Nieto, Elena; Pelembe, Tara; Vergílio, Marta H. S.; Burkhard, BenjaminMapping and Assessment of Ecosystems and their Services (MAES) has been widely applied on the European Union (EU) mainland, whereas the EU Overseas entities still bear potential for implementation. This paper presents novel applications of the MAES procedure in the EU Outermost Regions and Overseas Countries and Territories ("EU Overseas"). Eight case studies from different geographical areas were analysed through a comparative assessment by applying an established framework following key steps in the MAES process, in order to stipulate lessons learned and recommendations for MAES in the EU Overseas. These key steps include the identification of policy questions, stakeholder networks and involvement, application of MAES methods, dissemination and communication and implementation. The case studies were conducted and analysed under the umbrella of the EU MOVE pilot project, including the Azores, the Canary Islands, Saint Martin, French Guiana, Martinique, Reunion Island and the Falkland Islands. Each case study represented different governance, policy and decision-making frameworks towards biodiversity and environmental protection. Case studies predominantly addressed the policy domains of Nature and Biodiversity Conservation and Marine and Maritime Policy. Ecosystem Services (ES) were assessed across a wide range of themes, biomes and scales, focusing on terrestrial, coastal and marine ecosystems. Results show that the implementation of the case studies was accompanied by extensive communication and dissemination activities. First success stories were visible, where the MAES exercise led to meaningful uptake of the ES concept to policies and decision-making. Yet, there is still work to be done - major bottlenecks were identified related to the MAES implementation centring around financial resources, training and technical expertise. Addressing these aspects can contribute to an enhanced implementation of MAES in the EU Overseas in the future.

Parente, Manuela I.; Neto, Ana I.; Fletcher, Robert L.; Gil-Rodríguez, María C.; Haroun, Ricardo J.Two species of encrusting brown algae (Phaeophyceae) are newly recorded for the Salvage Islands (Madeira Archipelago) viz. Nemoderma tingitanum and Hapalospongidion macrocarpum. The species are described, and information is presented concerning their ecology, morphology and geographical distribution in the Atlantic.

- PARQMAR (INTERREG III-B 03/MAC/4.2/M9): caracterization, planning and management of diverse marine protected areas in the Macaronesian Archipelagos.Publication . Haroun, Ricardo J.; Araújo, Ricardo; Neto, Ana I.; Espinosa, Agustín; Jordan, Vítor
- PARQMAR: Characterization and management of marine protected areas of the Macaronesia – The cases of "Eco-parque Marinho do Funchal" (Madeira Is.), Santa Maria Is. (Azores), Tenerife Is. and Gran Canaria Is. (Canary Islands).Publication . Araújo, Ricardo; Delgado, João; Martín, Rafael; Haroun, Ricardo J.; Neto, Ana I.; Chavez, V.; Sanchez-Araña, J.The aim of this project is to promote conservation and sustainable use of coastal ecosystems in several MPAs located in different archipel agos of the Macaronesian Region: Azores, Madeira and Canary Islands (Central Atlantic Ocean) through a close transnational cooperation. The main benthic and fish communities are charact erized as well as the diverse economic activities performed inside the MPAs. The surveys are carried out both in the intertidal and in the subtidal areas of Santa Maria Isl and (Azores), the Eco-Parque Marinho do Funchal (Madeira) and in two coastal sectors in Gran Canaria and in Teneri fe Islands (Canary Islands). From the dat a obtained a zoning and management plan for each MPA will be done to support the sustainable use of their marine resources. PARQMAR is a project supported by the EU Initiative INTERREG III-B (Madei ra, Azores, Canari es), project PARQMAR (03/MAC/4.2/M9).

- Synthesis of meeting and recommendations from the Net-Biome round table discussion on "motivated" science on biodiversity management and use in support of overseas sutainable developmentPublication . Hawkins, Stephen J.; Feldmann, Philippe; Azevedo, José M. N.; Louis, Max; Haroun, Ricardo J.; Abreu, António DomingosThis brief report summarizes the deliberations of the Round-Table presentations and discussion held during the Net-Biome Final Meeting (Paris, 15 & 16 February, 2012). The participants identified relevant key issues to support of Biodiversity management and underpinning science in ORs and OCTs. Two major themes emerged: a) Policy context and engagement with stakeholders b) Major scientific opportunities for research in the ORs+OCTs.
