Minhocas exóticas como indicadoras de perturbação antrópica em áreas de floresta atlântica

RESUMEN. En el presente trabajo se evaluo el efecto de la perturbacion antropica en la incidencia de lombrices exoticas y nativas activas en la superficie del suelo en un area de bosque atlantico del estado de Sao Paulo, Brasil. Los oligoquetos fueron muestreados usando trampas (pitfall) en dos areas, una en donde hubo corte raso y quema y otra en donde solamente hubo corte selectivo. La mayor parte de los individuos (91.4%) fue colectada en el area en donde hubo corte raso y quema y todos eran especies exoticas ( Amynthas sp., A. gracilis , A. corticis ) o peregrinas ( Pontoscolex corethrurus ). El contraste del numero de individuos entre las dos areas sugiere que la perturbacion antropica influye en la actividad superficial y la abundancia de especies exoticas de lombrices y que estas presentan un uso potencial como indicadores biologicos.
