“…For example, survival of the 10 nondomestic felid species endemic to Latin America is particularly jeopardized by habitat loss, human-animal conflicts, and poaching [1] whereas tiger conservation in Asia is mainly by harvest of animals for traditional medicines used by at least a quarter of the world's human population [2]. One felid species in particular-the Iberian Lynx-is critically endangered (IUCN R. List 2009) mainly due to decimation of European rabbit (Oryctolagus cuniculus) populations, the lynx's main prey [3].…”

“…In these areas, the polecat is specialized in the predation on lagomorphs (Roger, 1991;Santos et al, 2009). However, rabbit populations are in steep decline for 25 years because of illness, such as the myxomatosis (Calvete et al, 1997) or the rabbit haemorrhagic disease (RHD) (Delibes-Mateos et al, 2009;Moreno et al, 2007), modification of its habitat and hunting (Calvete et al, 2006). Restocking operations are trying to rebuild these populations particularly in the Mediterranean region (Letty et al, 2006), but methods need to be improved (Calvete et al, 1997;Moreno et al, 2007).…”

Status del turón Mustela putorius (Linnaeus, 1758) en Francia e implicaciones para su gestión Mustela putorius (Linnaeus, 1758) ipurtatsaren estatusa Frantzian eta kudeaketarekin lotutako inplikazioak ABSTRACTThe polecat Mustela putorius Linnaeus, 1758 is an elusive species whose lifestyle is relatively unknown. In France, the species might be legally hunted. Knowledge of the distribution of the species on the national scale is a necessary prerequisite for the implementation of appropriated management and conservation measures. The National Wildlife and Hunting Agency (ONCFS) has developed a method for collecting data at the national scale so that to create presence maps of small and medium-sized carnivores. The presence map of the polecat is presented in this note, based on data collected from 2001 to 2010. The map shows that the species is fairly well distributed throughout the country with the exception of some regions that deserve further study. According to current knowledge, the factors threatening the polecat in France are above all the deep modifications of the preferential habitats of the polecat, particularly the important decrease of wetlands and hedged farmland; the increase of the road network and the poor state of rabbit Oryctolagus cuniculus (Linnaeus, 1758) populations, an important food resource notably in the Mediterranean regions. The importance of secondary rodenticide poisoning needs to be evaluated. We postulated that trapping is not nowadays a major threat to the species in France. Management and conservation measures of its habitat through the implementation of public policies could favor its maintenance.KEY WORDS: Conservation, Distribution, European polecat, France, Threats. RESUMENEl turón Mustela putorius Linnaeus, 1758 es una especie huidiza de costumbres poco conocidas. Su caza en Francia podriar estar permitida. Conocer la distribución del Turón en territorio nacional es indispensable para tomar medidas de gestión y de conservación apropiadas a su estatus. La Oficina Nacional de Caza y Fauna Salvaje (ONCFS) ha desarrollado un método de recogida de datos a escala nacional con el fin de realizar mapas de presencia de pequeños y medianos carnívoros. En este artículo, se muestra el mapa de presencia del Turón obtenido a partir de los datos recogidos del año 2001 al 2010. Éste, indica que la especie está bien distribuida en el territorio a excepción de algunas regiones que merecerían un más estudios. Basándonos en los conocimientos actuales, los factores que amenazan al Turón en Francia son sobre todo las enormes modificaciones de su hábitat, particularmente una disminución importante de los humedales y de las zonas boscosas; el aumento de la red de carreteras y el mal estado de ciertas poblaciones de conejos Oryctolagus cuniculus (Linnaeus, 1758), importante fuente alimenticia, especialmente en las regiones mediterráneas. La gestión y la conservación del hábitat del Turón a través de la realización de políticas públicas serían unas medidas que podrían favorecer el mantenimiento de es...

“…In 1989, RHD was introduced in the Iberian Peninsula and had immediate effects. The RHD virus suddenly killed up to 60% of wild rabbits in Doñana (Villafuerte et al 1994) whereas rabbit densities dropped by a factor of 5.7 and were kept at these very low levels at least for the next 15 years (Moreno et al 2007). As a result, some sites within the Doñana area had rabbit densities 100 times lower than those allowing lynx reproduction (López-Bao et al 2008).…”

During the last 70 years, the Iberian lynx Lynx pardinus has experienced dramatic changes in its environment, range size, and population size. In a context of widespread support for Iberian lynx conservation, its recent downgrading from Critically Endangered to Endangered in the IUCN Red List has drawn some public concern. Here we expand the summarized account published in the IUCN Red List website to illustrate how assessments are performed in well studied species. Assessment requires assignment to the highest threat category for which the species qualifies according to any of five criteria. Using 2012 as the reference year, no decline was observed during the last three lynx generations, and criteria regarding Population size reduction (A1, A2 and A4) were not met. Under criterion B (Geographic range) the species should be listed as Vulnerable. Considering Criterion D (Very small or restricted population), the Iberian lynx should be assigned to the Endangered category because in 2012 the estimated number of mature individuals (168) was under the established threshold of 250. A complex population model incorporating the combined effects of climate change, prey availability and conservation strategies reveals the critical need of maintaining current reintroduction efforts to avoid lynx extinction. If this condition is fulfilled, the species should be downgraded to Endangered under criterion E (Quantitative analysis). If reintroductions are discontinued, the category Endangered would be assigned under criteria A3 (Projected population reduction) and C (Small population and decline). We discuss the objectivity, transparency and conservation implications of the Iberian lynx downlisting. Keywords: geographic range, population models, reintroduction, risk factors, sustained management ResumenDurante los últimos 70 años, las condiciones ambientales, el área de distribución y el tamaño poblacional del lince ibérico Lynx pardinus han experimentado cambios sustanciales. Vivimos un periodo en el que la conservación del lince recibe un fuerte apoyo social y, en este contexto, la reciente catalogación de la especie como En Peligro en la Lista Roja de la UICN, rebajando su anterior estatus de En Peligro Crítico, ha despertado cierta preocupación. Usando el caso del lince ibérico, ilustramos con detalle cómo se evalúa el grado de amenaza y se catalogan en la Lista Roja de la IUCN las especies para las que existe mucha información biológica. Las especies deben catalogarse en la categoría de amenaza más alta resultante de la valoración independiente de cinco criterios. Tomando 2012 como el año de referencia, no encontramos indicios de declive desde hace tres generaciones y, por tanto, los criterios de reducción de tamaño poblacional A1, A2 y A4 no se cumplen. Considerando el criterio B, relativo a atributos del área de distribución, la especie debe clasificarse como Vulnerable. Según el criterio D, relativo a poblaciones pequeñas y de distribución restringida, el lince entra en la categoría En Peligro porque el número es...
