Los Coleópteros acuáticos amenazados (Coleoptera)

Abstract

[ES] Ochenta y ocho especies (incluidas 3 subespecies) de coleópteros acuáticos han sido recogidas en el Parque Nacional de Sierra Nevada (SE Iberia), de las cuales 15 son endemismos ibéricos y 4 (dos especies y dos subespecies) exclusivos del Parque. En los últimos muestreos realizados se han encontrado 49 especies y 7 endemismos, destacando la presencia de Agabus nevadensis Lindbeg, 1939 e Hydroporus sabaudus sierranevadensis Shaverdo, 2004, dos de los cuatro endemismos exclusivos de la zona de estudio y de los más amenazados en la Península Ibérica. Sierra Nevada presenta una riqueza menor a la observada en otros parques nacionales y áreas protegidas de superficie similar. Sin embargo, es muy rica en endemismos ibéricos, y el único Parque Nacional español con taxones reconocidos con distribución restringida a los límites del área protegida. La relativa baja riqueza de especies está relacionada con la homogeneidad de los ecosistemas acuáticos incluidos en el Parque, debido al carácter mayoritariamente silíceo de la zona y a las condiciones de extrema dureza ambiental propias de áreas con elevada altitud. Estas condiciones bioclimáticas son singulares en una región (SE Iberia) caracterizada, en general, por una menor altitud y temperaturas más suaves, importantes factores que podrían explicar la presencia en Sierra Nevada de algunos endemismos exclusivos.

[EN] Eighty eight species (plus 3 subspecies) of aquatic Coleoptera have so far been recorded in the Sierra Nevada Nacional Park (SE Iberia), 15 of them Iberian endemics and 4 (two species and two subspecies) exclusively found in the Park. In a recent sampling we collected 49 species of which 7 were Iberian endemics, including Agabus nevadensis Lindbeg, 1939 and Hydroporus sabaudus sierranevadensis Shaverdo, 2004, two of the four exclusive endemics from the study area and considered to be highly threatened in the Iberian Peninsula. The species richness of Sierra Nevada is lower than that of other National Parks and protected areas with a similar surface. Nevertheless, it is very rich in Iberian endemics, and the only Spanish National Park with recognized taxa restricted to the limits of the protected area. The relatively low species richness may be related to the homogeneity of the aquatic ecosystems included in the Park, due to the dominance of a siliceous substrate and the extreme environmental conditions typical of high altitude. These bioclimatic characteristics are singular in a region (SE Iberia) characterized by general lower altitudes and much milder temperatures, and could be an important factor to explain the presence in Sierra Nevada of some exclusive endemics.
