Macrofaunal contributions to benthic nutrient fluxes revealed by radium disequilibrium
Abstract The benthic flux of nutrients underpins marine food webs, influences conditions for life in the oceans, and contributes to climatic feedback. Estimates of these fluxes' contributions to macro‐ and micronutrient cycles are, however, highly variable, generating significant uncertainty in biogeochemical models.

While the Smithian–Spathian boundary carbon isotopic excursion has been traditionally interpreted as capturing global carbon cycle behaviour, recent studies have suggested that at least some Early Triassic carbon isotopic excursions may incorporate influences from authigenic or early diagenetic processes.

Gastropod classification and taxonomy [PDF]
Gastropods are a large and highly diversified class within the phylum Mollusca. Many gastropods possess a shell whereas some are without shells. The shelled gastropods are also called univalves.
