Published: 03 September 2020
...Alexander A. Venn; Coralie Bernardet; Apolline Chabenat; Eric Tambutté; Sylvie Tambutté ABSTRACT Coral calcification relies on the transport of ions and molecules to the extracellular calcifying medium (ECM). Little is known about paracellular transport (via intercellular junctions) in corals and...

These studies demonstrate the complexity of calcification pathways and the cellular responses of animals to these altered...

Ca 2+ influx across the nuchal organ and body surface of neonates but not embryos is presumably related to calcification of the exoskeleton. Increases in the levels of Na + and Ca 2+ in...

Thus, hydration of endogenous CO 2 forms HCO – 3 for calcification while hydrogen ions are excreted, contributing to continued...
