Una prueba biológica de la existencia de refugios glaciares ("nunataks") en el Pirineo occidental

Abstract

[ES] La existencia de macizos de refugio montañosos que sobresal ían de los hielos durante las glaciaciones cuaternarias habrá sido vislumbrada independientemente por biólogos y geólogos. Para el caso concreto del Pirineo centro-occidental el autor documenta esta idea con una lista de especies vegetales paleoendémicas, cuya abundancia en el piso supraforestal de las Sierras Interiores indica, en la mayoría de los casos, una larga evolución "in situ" de tales estirpes, seguramente desde tiempos precuaternarios. El estudio taxonómico, corológico y ecológico de las plantas endémicas pirenaicas suministra valiosos datos para la Biogeografía histórica.

[EN] Both geologists and biologists have been pointing out the existence of mountain refuges uncovered of ice along the Ouaternary periodo According with this idea, the author shows a list of paleoendemic plants whích are very abundant on the top of West Pyrenean mountains. Surely, these ancient taxa have undergone a very long evolution "in situ" from the Prequaternary ages to the present time. A taxonomical, chorological and ecological study of endemic pyrenean plants always provide substantial data to Historical Plant Geography.
