The variability of the bioaccumulation of metals (Ag, Cd, Cu, Fe, Mn and Zn) was extensively studied in the mussel Bathymodiolus azoricus from five hydrothermal vent sites inside three main vent fields of increasing depth along the Mid-Atlantic Ridge: Menez Gwen, Lucky Strike and Rainbow. Metal bioaccumulation varied greatly between vent fields and even between sites inside a vent field with B. azoricus showing a great capacity to accumulate metals. The bioaccumulation of these metals also varied significantly among tissues. The main target was the gills where metals were mainly associated with soluble compounds whereas in the digestive gland they were mainly associated with insoluble compounds. Storage of metals under insoluble forms in B. azoricus seems...

Late Maastrichtian-Danian Mytilids and Pinnids (Mollusca: Bivalvia) from Northern Patagonia, Argentina

Autores: Griffin,Miguel; Parras,Ana; Casadío,Silvio.
The Upper Cretaceous - lower Paleogene rocks from northern Patagonia yield a rich fauna of marine mollusks that may be useful in elucidating paleobiogeographic and paleoenvironmental changes taking place across the K/P boundary in the region. Most of the mollusk faunas remain poorly understood, as the preservation is generally deficient. This paper describes three new species of mytilids (Septifer mayai n. sp., Mytilaster ? edseli n. sp. and Gregariella amara n. sp.), and records four species of pinnids, one of which is new (Plesiopinna pampeana n. sp.). All the material comes from the Maastrichtian Jagüel Formation, and the Maastrichtian/Danian Roca Formation, exposed in the provinces of Río Negro, Mendoza and La Pampa (Argentina). A survey of the...
