Regulation of salt gland activity in the estuarine crocodile: phenotypic plasticity and control mechanisms. (2003-2005)
Abstract
The estuarine crocodile excretes excess sodium and chloride ions through salt glands located on the tongue, enabling the crocodile to live in seawater. This study will investigate the regulation of salt gland secretory capacity and activity, by examining both the phenotypic plasticity of the gland to changes in environmental salinity and diet, and by determining the neural/humoral mechanisms controlling secretory rate. In vivo measurements of blood flow and salt gland secretory rate, together with perfused gland preparations will reveal extrinsic and intrinsic factors controlling salt gland activity and the degree of coupling between blood flow and secretory rate.
