CIRCADIAN FLUCTUATIONS IN TOTAL PROTEIN AND CARBOHYDRATE CONTENT IN THE SLUGLAEVICAULIS ALTE(FERUSSAC, 1821)

Abstract

Rhythmic fluctuations in total protein and carbohydrates in the central nervous system, midgut gland, and foot muscle of Laevicaulis alte were not in phase with each other. Fluctuations were largest in the midgut gland. The occurrence of crest values during dark hours for total protein and light hours for total carbohydrates, high protein levels during the dark span and high carbohydrates during light, may be related to the animal's motor functions. Percent loss of water content was bimodal in all three tissues studied.
