Physiological, environmental, and mineralogical controls on Mg and Sr concentrations inNautilus

Abstract: Describing the chemical ontogeny of 36 specimens of Nautilus allowed the identification, as well as the determination of the relative effects, of the controls on Mg and Sr concentration in skeletal aragonite. The previously documented trend that aragonite contains higher concentrations of Sr than Mg persists within skeletal structures of Nautilus. This relationship suggests that neither physiological nor environmental controls overwhelm the mineralogical control. Significant differences in Mg and Sr concentrat… Show more

“…In a study of Mg and Sr concentrations in nautilus shells, Mann (1992) found consistently higher and more variable elemental concentrations in carbonate formed earlier in life. Three possible explanations are given: (1) an age-related change in biomineralization, wherein elemental concentrations depend on carbonate accretion rates; (2) maturation of the biomineralization system, which results in increased control over shell chemistry; or (3) larvae are exposed to stresses related to food acquisition and protection -stresses less problematic in older organisms.…”

“…These intense morphological and developmental changes occurring during PI production are likely to cause significant differences in elemental uptake compared to juvenile shell production when the mantle has formed completely. Our results lend support to the idea that the effects of physiology on larval and juvenile shell production are sufficiently different to affect uptake and incorporation of elements into carbonate.In a study of Mg and Sr concentrations in nautilus shells, Mann (1992) found consistently higher and more variable elemental concentrations in carbonate formed earlier in life.

“…Chemical intra-shell variations in biogenic carbonates may include environmental (water chemistry, temperature, primary productivity) and biological factors (vital effects and growth rates) as the main influences (Eisma et al 1976;Carpenter and Lohmann 1992;Mann 1992;Klein et al 1996aKlein et al , 1996b, the latter largely depending on taxonomic and ontogenetic factors. Indeed, precipitation of LMC shells involves biological discrimination against seawater Mg 2+ and thus shells grow out of equilibrium with seawater (Lorens and Bender 1980).…”
