Tal es la su auze : El héroe afortunado del Cantar de Mio Cid

El protagonista del Cantar de mio Cid es un héore mesurado, pero también afortunado, agraciado con auze o buenaventura y "en buen hora nado". Su fortuna es innata, pero también cultivada a través de la prudencia. La suma de templanza y osadía sirva para mantener el auze del Campeador, lo que, unido al optimismo del héroe afortunado, impregna el poema épico de un fuerte dinamismo.

Bivalve mollusks in the sediments of the Anapa Bay Bar (Black Sea) in October 2010

Sandy beaches of the Anapa Bay Bar are a unique natural resource, but they are gradually being degrade under both natural and anthropogenic factors. Emissions of sand and shelly ground from the adjacent sea bottom partly compensate for this process. Concentration of carbonates may reach up to 50% in beach sands, and most of these carbonates are of mollusk origin. The major deposit formation role belongs to the key bivalve species: Chamelea gallina (Linnaeus, 1758). Average biomass of this mollusk species reaches up to 450 g/m**2 at depths 5-10 m. The other two subdominating mollusk species, bivalve Donax trunculus (Linnaeus, 1758) and gastropod Rapana venosa (Valenciennes, 1846), may impact as 16 g/m**2 and 6 g/m**2, respectively. Annually, 350 kg of shelly ground per running meter are newly deposited on the Anapa beach.
