Abstract
The amount of structural and storage lipids and the composition of fatty acids (FA) in the symbiotic hydroid coral Millepora dichotoma were determined monthly throughout the year. In the first half of the year, the hydrocoral actively accumulated lipids, as indicated by a twofold increase in the content of reserve lipid classes of (waxes, triglycerides, and monoalkyl diacyl glycerides) concurrent with a relatively stable level of polar phospholipids (PL) and sterols. There was a decrease in the proportion between choline and ethanolamine glycerophospholipids (PC/PE) in July, a sharp drop in the content of triglycerides in August, and a large dispersion the PL values in September, which may be due to energy expenditures and structural changes in the colonies during spawning. The level of 22:6n-3, which is synthesized in hydrocoral from FA of plankton, was maximum in the summer, and the level of 18:4n-3, the FA marker of photosynthetic symbionts, doubled in the winter. This indicates the predominance of the heterotrophic mode of nutrition in M. dichotoma in the summer and an increased role of symbionts (an autotrophic food source) in the winter with a drop in water temperature and the onset of a stormy period.
