The role of kleptoplasts in the survival rates of Elysia timida (Risso, 1818): (Sacoglossa: Opisthobranchia) during periods of food shortage
چکیده انگلیسی

The importance of photosynthetic products derived from kleptoplasts in several sacoglossan species is being investigated in different fields, such as chemistry, biomolecular genetics and ecology. This study analyzes the effect of kleptoplasts on the survival rates of Elysia timida by evaluating the development of chlorophyll concentration, total length and survival rates of starved E. timida specimens kept in the light and in the dark. Although chlorophyll concentration values were similar in both cases, after 28 days specimens kept in the dark showed a greater size decrease and a lower survival rate (up to 30% lower) than those kept in the light. It is evident that kleptoplasts provide the mollusc with extra energy at the primary metabolism level to compensate for a shortage in food.
