El presente artículo presenta un resumen de la información histórica de presencia del águila de Bonelli en las Baleares, los planteamientos y desarrollo del Pla de Recuperación y los resultados iniciales de las actividades de recuperación, enmarcadas en el proyecto LIFE de conservación integral de la especie. Se destaca la buena tasa de supervivencia de los ejemplares liberados, con una descripción y comparación de las técnicas utiliuzadas; y el éxito inicial que supone la reproducción en la Serra de Tramuntana de una pareja de la especie en 2013

Consorci per a la Recuperació de la Fauna de les Illes Balears, 11 años trabajando para la conservación de la biodiversidad

El COFIB, Consorci per a la Recuperació de la Fauna de las Illes Balears se creó en el año 2004 con la finalidad de atender las necesidades de recuperación de la fauna silvestre así como gestionar problemáticas relacionadas con la fauna exótica. Las entidades que lo constituyen son la Conselleria de Agricultura, Medi Ambient i Territori del Govern de les Illes Balears y la Fundació Natura Parc, entidades que aportan los medios necesarios para llevar a cabo las actividades del Consorcio. Durante estos años se han atendido 26.119 casos de fauna silvestre de las Islas Baleares y se han recogido 4.148 ejemplares de fauna exótica. Se ha participado en diferentes planes de conservación y recuperación que lleva a cabo el Servei de Protecció d’Espècies de la DG de Medi Natural. Los cuatro últimos años se ha incorporado el equipo de Sanidad y Control de Fauna, que interviene en acciones de control de especies invasoras y domésticas asilvestradas en diferentes espacios de la R.N.2000 y que ha capturado 11.622 especímenes de 25 especies distintas. Se colabora y participa en el seguimiento y monitorización de las enfermedades que afectan a la fauna silvestre. Desde el año 201,2 el COFIB coordina la recuperación de ejemplares de la fauna silvestre en todas las Islas Baleares. Gracias a los datos obtenidos a lo largo de estos 11 años, se ha contribuido en líneas de investigación y publicaciones que mejoran el conocimiento sobre nuestras especies. Finalmente, la educación ambiental y la investigación complementan las acciones de recuperación que lleva a cabo el COFIB. El artículo repasa algunas de las actuaciones, resultados y los datos más importantes recogidos durante este periodo

Origin and introduction history of the least weasel (Mustela nivalis) on Mediterranean and Atlantic islands inferred from genetic data

WOS: 000392187700028Introduced mammalian predators have negatively affected native biota and ecological processes in ecosystems across the globe. The least weasel (Mustela nivalis) is a Holarctic mustelid carnivore that has been considered one of the world's worst invasive alien species. It has been introduced to several islands in the Mediterranean Sea and Atlantic Ocean, and here we present a genetic analysis of these insular populations, based on mitochondrial DNA and microsatellites and building upon a previous Western Palearctic phylogeographic study, with the aim of inferring their origin and introduction history. This is essential information for ecological and evolutionary studies of those populations and our understanding of their impacts on the islands' biodiversity. Among the Mediterranean insular populations, a substantial mitochondrial subdivision between weasels in Sicily-Corsica and Malta-Sardinia-Balearics is best explained by a dual colonization originating from the Eastern Mediterranean. Given the correspondence between the observed genetic partition and the differential geographic distribution of Greek and Phoenician settlements and influence during the last millennium BC in those islands, we propose that weasels may have been introduced into the first group of islands by the Greeks and into the second group by the Phoenicians. There is strong support that the commercial and demographic expansions of Phoenicians and Greeks allowed the colonization of the western Mediterranean islands by the house mouse, and texts from Classical Antiquity show evidence that weasels were used for rodent control. Thus, weasels may have been intentionally introduced to the islands, with the aim of controlling commensal rodents. Besides indicating Eastern Mediterranean origins for weasels in Mediterranean islands, the mitochondrial data also revealed an unanticipated close genealogical connection between some of these populations and those from the Azores and So Tom,. The latter island populations showed no affinities with weasels from mainland Portugal, contrary to what might have been expected given that these Atlantic islands were settled by the Portuguese. The microsatellite data also supported the relationship between weasels in Atlantic and in Mediterranean islands. Considering geographic proximity and historical information, the most parsimonious explanation for the origin of the Atlantic weasels appears to be introduction from the Balearic Islands to the Azores and from there to Sao Tome.Portuguese National Funds through Fundacao para a Ciencia e a Tecnologia (FCT) [UID/BIA/00329/2013]; Fundacao para a Ciencia e Tecnologia (FCT, MCTES, Portugal) [SFRH/BD/60595/2009, SFRH/BPD/91494/2012]; Ciencia [C2007-UL-342-CBA1]; Academy of FinlandAcademy of Finland [200940, 108601, 118673]; American University in Cairo through a faculty research grant; Turkish National Science Foundation (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [110T930]We thank Jean-Francois Noblet, Wissem Ghawar (Institut Pasteur de Tunis), Maurizio Gattabria (Museo Civico di Zoologia di Roma), Federico Striglioni and Gino Damiani (Parco Nazionale del Gran Sasso e Monti della Laga) and Parco Nazionale d'Abruzzo, Lazio e Molise for providing samples, Fatima Sobral and Ana Simoes Nunes (DGV) for kindly providing access to an automated sequencer, and Arlindo Carvalho (Sao Tome and Principe General-Directorate for the Environment) for the permit to collect and export samples.
