Resumen
[ES]Estudio de nematodos de vida libre que aparecen en excrementos de conejo procedentes de suelo de
olivar en Jaén para determinar qué porcentaje de nematofauna del suelo de olivar pasan al
excremento para utilizarlo como fuente de alimento, bien bacterias u hongos coprófilos, o nematodos
depredadores de otros nematodos. Se analizaron excrementos en dos tipos de olivar de secano y
regadío, debido a que, abundancia y diversidad, varían en función de la humedad del suelo. Del total
de muestras examinadas se han encontrado 16 especies pertenecientes a cinco órdenes y 12 familias,
11 especies aparecen en suelo y nueve en excremento. Además, se ha encontrado en las heces una
especie parásita del conejo, Nematodirus filicollis. Los resultados indican que en suelo el orden más
abundante es Dorylaimida y en excrementos el orden Rhabditida, especialmente Panagrolaimus
rigidus. De todas las especies se aportan descripción e ilustraciones.
[EN]Study of free living nematodes from rabbit excrements appearing in soil samples from olive culture in Jaén to determinate what percentage of soil nematofauna could colonize these excrement for use that as food source, either bacteria or dung fungi, or predator nematodes of other nematodes. Two types of olive cultures have been sampled according its type of irrigation (rainfed and irrigated) because abundance and diversity of nematodes is modified depending on soil humidity. Sixteen species were found belonging to five orders and 12 families, where 11 species have appeared in soil and nine in excrement. Furthermore, a parasitic nematode of rabbit, Nematodirus filicollis, has been found in the feces examined. After this study it is observed that the most abundant order in soil is Dorylaimida, while the most abundant order in excrement corresponds to Rhabditida, especially Panagrolaimus rigidus. Descriptions and illustrations with optical microscope are provided for all species.
