The importance of intraespeciphic variation in the taxonomy of marine nematodes: The case of Terschellingia longispiculata Wieser & Hopper 1967 (Nematoda, Linhomoeidae)

In the presentstudy, the priority of taxonomic characters of cephalic region of Terschellingialongispiculata over those of the tail and reproductive system is discussed.Four morphological varieties of the species are established based on variationsof the tail and reproductive system. The problem of considering only changes inthe posterior region for determination of some species is posed. From this,studies on important populations must be done for the establishment of newspecies based on one of these characters, but taken together with characters inother regions such as the cephalic.

Estratigrafía del Paleógeno en la zona de tránsito entre la Cordillera Prelitoral Catalana y el Prepirineo

La serie de Eoceno y Paleoceno de El Far (provincia de Gerona), presenta un gran interés por servir de punto de enlace entre el Paleógeno de la Cordillera Prelitoral Catalana (en la zona de la Plana de Vic) y el Prepirineo. Es por ello que lieinos considerado interesante el pulilicar una serie detallada que sirva de jalón para poder correlacionar el Eoceno de la Plana de Vic con el de La Salut, Bellmunt y Puigsacalm, sobre todo en los tramos inferiores. Ambas series eocénicas poseen diferencias muy notables en su litología (cainbios laterales de facies) y potencia (aumento pogresivo hacia el surco paleógeno prepirenaico), lo que influye en la misma fauna...
