Organic membranes determine the pattern of the columnar prismatic layer of mollusc shells.
The degree to which biological control is exercised compared to physical control of the organization of biogenic materials is a central theme in biomineralization. We show that the outlines of biogenic calcite domains with organic membranes are always of simple geometries, while without they are much more complex. Moreover, the mineral prisms enclosed within the organic membranes are frequently...
متن کاملThe effects of exposure to near-future levels of ocean acidification on shell characteristics of Pinctada fucata (Bivalvia: Pteriidae)
Atmospheric carbon dioxide concentrations have greatly increased since the beginning of the industrial age. This has led to a decline in global ocean pH by 0.1 units, and continued decline of 0.3–0.5 units is predicted by the end of 2100. Acidification of the ocean has led to decreased calcification rates and dissolution of calcareous structures in a range of marine species. Shells of the pearl...
متن کاملCharacterization of Prismalin-14, a novel matrix protein from the prismatic layer of the Japanese pearl oyster (Pinctada fucata).
The mollusc shell is a hard tissue consisting of calcium carbonate and organic matrices. The organic matrices are believed to play important roles in shell formation. In the present study, we extracted and purified a novel matrix protein, named Prismalin-14, from the acid-insoluble fraction of the prismatic layer of the shell of the Japanese pearl oyster (Pinctada fucata), and determined its wh...
متن کاملOn the occurrence of Pinctada radiata (Mollusca: Bivalvia: Pteriidae), an alien species in Croatian waters
The family Pteriidae (Bivalvia: Pterioida), which includes the group of species known as “pearl oysters” comprises three genera, namely Pteria Scopoli, 1777, Pinctada röding, 1798 and electroma Stoliczka, 1871 (CLEMAM, 2008). This family is represented by three species (Pteria hirundo (Linné, 1758); Pinctada radiata (Leach, 1814) and electroma vexillum (Reeve, 1857)) in the Mediterranean accord...
متن کاملInvestigation of Two-dimensional Models of Elastic Prismatic Shell
Statical and dynamical two-dimensional models of a prismatic elastic shell are constructed. The existence and uniqueness of solutions of the corresponding boundary and initial boundary value problems are proved, the rate of approximation of the solution of a three-dimensional problem by the vector-function restored from the solution of a two-dimensional one is estimated. 2000 Mathematics Subjec...
