Resumen
[ES] Este trabajo presenta un estudio de la fauna del orden Dorylaimida (Nematoda) en dos
dolinas y su matriz circundante en la Sierra de la Pandera, provincia de Jaén. Se han
identificado 306 individuos pertenecientes a 12 especies, 11 géneros y 9 familias, que
fueron recolectados en 15 muestras de suelo. Tanto la diversidad (5,4 especies por
muestra en la matriz vs 4,0 y 3,0 en las dolinas) como la abundancia (20,6 individuos por
muestra vs 16,6 y 23,8) de la dorilaimofauna presentan valores muy bajos respecto a lo
esperado, seguramente debido al estrés hídrico sufrido por el área estudiada. No se han
encontrado diferencias significativas ni en la distribución de la diversidad (riqueza
específica) ni en la distribución de la abundancia entre los grupos de muestras
considerados. No existen diferencias significativas en la composición y estructura de las
comunidades nematológicas de las dolinas y de su matriz circundante.
[EN] This project presents a study of the fauna of the Dorylaimida (Nematoda) order in two sinkholes and its surrounding matrix in the Sierra de la Pandera, Jaén province. 306 individuals belonging to 12 species, 11 genera and 9 families have been identified, which were collected in 15 soil samples. Both the diversity (5.4 species per sample in the matrix vs 4.0 and 3.0 in the sinkholes) and the abundance (20.6 individuals per sample vs 16.6 and 23.8) of the dorilaimofauna show very high values. lower than expected, probably due to water stress suffered by the studied area. No significant differences were found either in the distribution of diversity (specific richness) nor in the distribution of abundance between the sample groups considered. There are no significant differences in the composition and structure of the nematological communities of the sinkholes and their surrounding matrix.
