SEASONAL PATTERNS IN THE BIOCHEMICAL CONSTITUENTS AND BODY COMPONENT INDEXES OF THE MURICID GASTROPOD,THAIS HAEMASTOMA

open access: hybridThe Biological Bulletin, 1978
1. Seasonal changes in the body component indexes of Thais haemastoma were studied over a 15 month period. Seasonal changes in the protein, carbohydrate and lipid level and content were determined for soft components over a 12 month period.2.

VOLUME REGULATION AND NITROGEN METABOLISM IN THE MURICID GASTROPOD THAIS HAEMASTOMA

open access: closedThe Biological Bulletin, 1985
Ammonia and primary amine excretion and concentrations of intracellular ninhydrin-positive substance (NPS) and free amino acids (FAA) were measured in Thais haemastoma acclimated to salinities between 5 and 35%o and over 14 days following direct transfer from 10 to 3O%o or from 30 to lO%o. There was no trend in excretion rates with acclimation salinity.
