Estudio Sobre Los Posibles Depredadores Del Erizo Irregular Brissus Unicolor (Leske, 1778)

Los caparazones del erizo de mar irregular Brissus unicolor (Leske, 1778), que aparecen frecuentemente en los fondos someros de las islas Canarias, presentan en su mayoría una perforación muy evidente. Este trabajo de fin de grado pretende estudiar las características y ocurrencia de esta perforación con el fin de determinar sus posibles causantes. Se recolectaron un total de 104 caparazones de B. unicolor en 15 localidades de la isla de Tenerife. El 94% de ellos presentaba al menos una marca de depredación por perforación. -

Insgesamt können 24 Arten nachgewiesen werden. Tonnoidea weisen generell eine ungewöhnliche weite geographische und stratigraphische Verbreitung auf, wie sie bei anderen Gastropoden unbekannt ist. Dementsprechend sind die paratethyalen Arten meist auch in der mediterranen und der atlantischen Bioprovinz vertreten. Einige Arten treten zuerst im mittleren Miozän der Paratethys auf. Insgesamt dokumentiert die Verteilung der tonnoiden Gastropoden in der Parate- thys einen starken klimatischen Einfluss. -

The large diversity of the species characterized the mollusc fauna from the famous occurrences of the Făget Basin (Lăpugiu de Sus, Nemeşeşti, Coştei). The assemblage from Lăpugiu de Sus represents one of the richest European Badenian fossil fauna. The collected gastropods (190 specimens) have been determined, systematically arranged and illustrated. The 54 species recorded belong to 20 families (Neritopsidae, Cerithiidae, Turritellidae, Cypraeidae, Pediculariidae, Ficidae, Naticidae, Aporrhaidae, Tonnidae, Buccinidae, Columbellidae, Fasciolariidae, Nassariidae, Muricidae, Mitridae, Volutidae, Olividae, Conidae, Terebridae and Turridae).

The context of the project is included within our mission and exclusive dedication to researching, protecting and recuperating the oceans through investigation and scientific work, with a focus on biodiversity, the environment and sustainable marine development. As part of a general diagnosis, the most environmentally important habitats have been identified in this report according to their unique qualities and biological and biogeographical interest. The following chapters detail research results and include proposals for representative types of natural habitats of interest to the European Community. -

O. VAN REGTEREN ALTENA (Rijksmuseum van Natuurlijke Historie, Leiden) INTRODUCTION The palaeolithic deposits of the rock shelter of Ksar'Akil in the Antelias valley have been excavated by a group of American Jesuits in the years I937-I938 and 1947-1948. Recently the fossil bones from these deposits were reported upon by my colleague Hooijer (1961). When he received the material for description it appeared that his samples contained a large collec• tion of molluscan shells and a few spines of echinoderms as well. These are dealt with in the present paper. To the best of my knowledge they are all the remains of molluscs and echinoderms found during the excavation. For further details on the collection and the site I refer to Hooijer's paper, which also contains references to the literature on Ksar'Akil. A few shells from the neighbouring site Abri Bergy (cf. Hooijer, 1961, p. 56) are mentioned in my list of Mollusca under nos. 6 and 26. MOLLUSCA Shells of 45 species of Mollusca have been collected in the rock shelter of Ksar'Akil. They belong to marine, freshwater, and terrestrial molluscs. All the species recorded are still living in the neighbourhood of the locality. The following is an annotated list of these Mollusca. Unless otherwise stated the data on the bathymetrical distribution of marine species have been borrowed from the list on page 808 seq.
