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. The Island Biology Interest Group (IBIG, http://www.ibigbiology.com) is grateful to the organisers of the 2016 Island Biology Conference held in the Azores for promoting the symposium that led to this manuscript. We thank Joaquin Hortal for useful comments on an early version of the manuscript, and also Guido Jones for his language editing funded by the Cabildo de Tenerife, under the TFinnova Programme supported by MEDI and FDCAN funds. We are grateful to Salvador de la Cruz and Elena Morales for extracting updated information from the Biodiversity Data Bank of the Canary Islands. We also thank Ricardo Ramalho (Cardiff University) for fruitful discussions on the geological age of the Cabo Verde islands.

La biodiversidad del sistema se mantiene gracias a lagran abundancia y heterogeneidad de lagunas y a su amplio gradiente de hidroperiodo, así como porla diferenciación geomorfológica del parque. Las principales amenazas para la conservación del sistema son la desecación y la introducción de es-pecies invasoras, como el cangrejo rojo americano (Procambarus clarkii). Se detectan tendencias impor-tantes de desecación asociadas a la sobreexplotación del acuífero en los alrededores del parque, queafecta también a las mayores lagunas del parque. Como consecuencia de los descensos del acuífero, seestá produciendo el acortamiento del hidroperiodo de las lagunas y la pérdida de las especies propiasde los medios más permanentes. Entre ellas destacan algunas con alto valor de conservación, que ac-tualmente restringen su distribución a lagunas profundizadas artificialmente (denominadas localmentezacallones), ya que son los únicos medios que actualmente se pueden considerar permanentes. Mientrasque no se solucionen los graves problemas que conllevan los descensos del acuífero, los zacallones tie-nen en la actualidad un importante valor para mantener la diversidad del sistema, por lo que requierenun plan de mantenimiento y gestión, [EN]: The Doñana temporary pond network is characterized by a high flora and fauna species richness, in-cluding a high number of rare and threatened species. This high biodiversity is due to the high abun-dance of ponds of different size across a broad hydroperiod range. The different geomorphologicalareas within the park contribute to increase the heterogeneity of the whole pond network. Two main problems are currently threatening the conservation of the pond network: the observed trendsof pond desiccation and the introduction of invasive species, such as the swamp crayfish (Procambarusclarkii). Desiccation trends are currently detected associated with groundwater overexploitation in agri-cultural and urban areas around the park. As a consequence, we detect a tendency to pond hydroperiodshortening that involves the loss of aquatic species requiring longer inundation cycles, being some ofthem threatened species. These species are presently only found in ponds that have been artificiallydeepened (“zacallones”) so they offer available water during summer or in dry periods. These semiar-tificial ponds have an important role for preservation of aquatic communities and should be includedinto a management plan for conservation of the biodiversity of the pond network.

Islands harbour evolutionary and ecologically unique biota, which are currently disproportionately threatened by a multitude of anthropogenic factors, including habitat loss, invasive species and climate change. Native forests on oceanic islands are important refugia for endemic species, many of which are rare and highly threatened. Long-term monitoring schemes for those biota and ecosystems are urgently needed: (i) to provide quantitative baselines for detecting changes within island ecosystems, (ii) to evaluate the effectiveness of conservation and management actions, and (iii) to identify general ecological patterns and processes using multiple island systems as repeated ‘natural experiments’. In this contribution, we call for a Global Island Monitoring Scheme (GIMS) for monitoring the remaining native island forests, using bryophytes, vascular plants, selected groups of arthropods and vertebrates as model taxa. As a basis for the GIMS, we also present new, optimized monitoring protocols for bryophytes and arthropods that were developed based on former standardized inventory protocols. Effective inventorying and monitoring of native island forests will require: (i) permanent plots covering diverse ecological gradients (e.g. elevation, age of terrain, anthropogenic disturbance); (ii) a multiple-taxa approach that is based on standardized and replicable protocols; (iii) a common set of indicator taxa and community properties that are indicative of native island forests’ welfare, building on, and harmonized with existing sampling and monitoring efforts; (iv) capacity building and training of local researchers, collaboration and continuous dialogue with local stakeholders; and (v) long-term commitment by funding agencies to maintain a global network of native island forest monitoring plots., Biodiversity and Conservation, 27 (10), ISSN:1572-9710, ISSN:0960-3115

Póster presentado en el 7th European Pond Conservation Network Workshop + LIFE Charco Seminar 1st May – 4th May 2017 Universidade do Algarve, Faro, Portugal, The pond network in the Doñana National Park, in SW Spain, is composed of more than 3000 temporary ponds that are usually dry during summer. This network is complemented with approximately 200 artificially deepened ponds that were transformed for old human uses (i. e., cattle drinking, farm irrigation, charcoal production). They are locally known as “zacallones”. We have recorded plant and animal species present in zacallones in order to assess their value for conservation. These water bodies act as permanent ponds; they are the reproductive habitats of those species with long larval phases, and the summer refuges of many coleopterans and heteropterans. They are also the habitats of plants that do not resist long dry phases. Some of these ponds are subject to occasional restoration tasks that mainly consist in the removal of thick bottom layers of mud. We have analysed and compared the water quality, and also animal and plant species richness of these ponds during two subsequent years after these tasks. Water quality was generally better in restored zacallones, and vegetation cover as well as animal and plant richness also increased. In unrestored zacallones, the concentration of total-P in the water was significantly higher than in recently restored sites. Additionally, the P-adsorption capacity of the sediment (estimated as the ratio between iron-hydroxides and P-inorganic fractions) was significantly higher in the restored sites. The removal of the bottom layer did not prevent the development of a rich community of aquatic macrophytes, including some threatened species. Our results suggest that zacallones can provide refuge to some significant species, particularly in recent years as the Doñana temporary ponds are being reduced in number and wet-phase duration (or hydroperiod). However, the water quality of these transformed ponds can deteriorate very rapidly (due to their small size and intensive use for wild fauna and cattle drinking), and hence they require periodical monitoring and management.

La importancia del sistema de lagunas de Doñana radica en la gran cantidad de lagunas y su elevada heterogeneidad, lo que le permite albergar a un gran número de especies, muchas de ellas singulares, al ser exclusivas de este tipo de medios acuáticos, caracterizados por un periodo de desecadón recurrente. Esta compleja red de lagunas se ha ido conformando, a lo largo del tiempo, coroo consecuencia de la interacción de los aprovechamientos tradicionales del suelo sobre las coodiciones hidrogeolágicas del manto eólico litoral onubense, en un contexto donde fluctúan períodos dimaticamente húmedos y secos.

The Doñana National Park is given the highest degree of environmental protection in Spain as it has been designated as a Ramsar Site, a Biosphere Reserve, a Special Protection Area for birds, and a Natural World Heritage Site. Nevertheless, it is located in an area with a wide variety of pressures due to the exploitation of water resources. The intensification of agriculture, urban growth, and the development of tourist resorts on the fringe of this protected land has long threatened the conservation value of the Doñana National Park and has, consequently, added this park to the Montreux Record of Ramsar Sites under threat in 1990.

Mediterranean temporary ponds are a priority habitat under the European Union Habitats Directive, but those of natural origin are scarce, as many of them have been destroyed or transformed into permanent waters. The aim of this study is to highlight the conservation value of the system of temporary ponds in Doñana National Park, where more than 3000 water bodies may be filled during wet years. They are located on soils of aeolian origin where water persistence is favoured by the presence of an argilic semi permeable horizon and by a relic clay-rich sandy layer. Temporary ponds can be classified across a wide hydroperiod gradient. Most ponds fill with autumnal or winter rains and persist up to late spring or summer, and only a few may persist through summer. Eight of the 11 amphibian species of this area require temporary ponds for breeding. More than 124 taxa of macroinvertebrates have been recorded, coleopterans (56 taxa) and heteropterans (19 taxa) being the richest taxonomic groups. Several zooplankton species are endemic to this kind of habitats, such as the copepod Dussartius baeticus and the rotifer Lecane donyanensis. Regarding vegetation, at least 55 hydrophytes species were identified in the ponds sampled, and also some species endemic to SW Iberian Peninsula (Callitriche regis-jubae, Scorzonera fistulosa, Callitriche lusitanica) and others are in relic situation (Hydrocharis morsus-ranae, Thorella verticillato-inundata, Lemna trisulca). The conservation value of these ponds is highlighted by the large variety of protected and/or rare species of flora and fauna, which are favoured by a high pond abundance and connectivity. © Asociación Ibérica de Limnología, Madrid.

13 páginas.-- 3 figuras.-- 4 tablas.-- 47 referencias, Geomorphological and hydrological features can provide a sound basis for global wetland classification. Temporary ponds located on the sandy area of Doñana can be classified into five different geomorphological areas. We hypothesised that these ponds would differ in soil characteristics, which may also explain differences in the composition of their macroinvertebrate, amphibian, and aquatic plant species assemblages. The study ponds were significantly segregated into southern and northern geomorphological areas based on the depth to the water table. The results of the multivariate ordination of soil variables were consistent with a north-south segregation, which was explained by the carbonate and other main ion concentrations in the pond basins. The ponds located in ecotones (marsh-sand and stable-mobile dunes) were particularly rich in amphibians and macroinvertebrates. This result may be explained because the ponds with the longest permanence of water were located in these areas, which represented the only flooded ponds during droughts. In addition, they also contained a high number of temporary ponds, thus favouring connectivity and environmental heterogeneity in these areas., This study was funded by the Spanish Ministry of Agriculture, Food and Environment (project 158/2010).
