Resumen
[ES] En este trabajo se realiza un estudio de la nematofauna (Dorylaimida y Mononchida) de diez muestras de suelo del encinar de Mata-Bejid, Parque Natural de Sierra Mágina, de Jaén. La extracción se ha hecho por centrifugación, y en glicerina anhidra. Se ha identificado 369 individuos de 30 especies, 20 géneros y siete familias. Cuatro especies se citan por primera vez en suelos de encinar. Para cada especie se ha determinado su frecuencia y abundancia. Tres especies son las más frecuentes, y siete las más abundantes. La mayor parte de la taxocenosis se compone especies cosmopolitas y holárticas, con una menor proporción de endemismos ibéricos, y una sola especie mediterránea. Los resultados obtenidos son similares a los previamente conocidos, pero se han encontrado diferencias en las especies presentes y su distribución, seguramente debido a la utilización de diferentes métodos de muestreo y de extracción de los nematodos.
[EN] Nematodes belonging to the orders Dorylaimida and Mononchida, collected from ten soil samples in Mata-Bejid holm-oak forest, Sierra Mágina Natural Park of Jaén, are studied in this contribution. They were extracted by a centrifugation method, and mounted in anhydrous glycerol. 369 specimens, 30 species, 20 genera and seven families. Four species are found associated to oak forest for the first time. Frequency and abundance are calculated far each species. Two species are the most frequent, and / species the most abundant ones. Most part of the nematode community consists of cosmopolitan and holartic species, with a lower proportion of endemic iberian species, and only one typical species of the Mediterranean. The results obtained are generally similar to those previously known in others Mediterranean habitats, but sorne important differences are found in species composition as well their distribution data, certainly due to the use of different methods of sampling and extraction.
