Dynamiques et évolutions morpho-sédimentaires de l’avant-plage du secteur littoral de Combrit – Île-Tudy entre le XIXe et le XXIe siècle

Nearshore is an integrated part of the coastal zone, as well as beaches and coastal dunes. However, they remain poorly studied compared to the emerged part of the system, because of the limited access for scientific monitoring. The nearshore of Combrit - Ile-Tudy (south Brittany, France), addressed in this paper, is a good example. The first aim of this study is to present a methodology for the interpretation of old bathymetric surveys (supplied by the French naval hydrographic and oceanographic service SHOM) which considers all the inaccuracies related to this type of data. Then, this method is implemented in order to depict the morphological evolution of the nearshore by comparing the ancient bathymetric surveys (19th and 20th centuries) and the recent...

Disjoint geographical distribution of intertidal and nearshore benthic invertebrates in the Southern Hemisphere
Provedor de dados: 97
Autores: CASTILLA,JUAN C; GUIÑEZ,RICARDO.
Biogeographical explanations for the extant and paleo disjoint geographical distribution in the southern hemisphere of five species of nearshore marine benthic invertebrates: Gaimardia trapesina, Ostrea chilensis, Pyura stolonifera taxonomic complex, Aulacomya ater and Concholepas concholepas, showing distinctive reproductive strategies and early life history characteristics are reviewed and analyzed. Through the use of published and new information we contrasted the following hypotheses: a) vicariance-historical process, b) epiplanktonic larval dispersal, c) juvenile/adult dispersal through rafting and d) planned or accidental anthropogenic dispersal mechanisms. The juvenile/adult transoceanic dispersal hypothesis by rafting was the only one impossible to...
