Functioning of the Lubomirskia baicalensis symbiotic community under the conditions of a model experiment
AbstractExperiments on keeping Lubomirskia baicalenis in temperature-controlled aquarium installations have indicated that after three months of incubation of the sponge with the temperature rise from + 4 to +12 quantitative biochemical parameters of cells in both the sponge itself and its symbionts change. The results of the experiment have revealed that when the water temperature rises above the ecological optimum for the endemic species of the Baikal sponge, Lubomirskia baicalenis, the quantitative composition of demospongic acids will change. The cells of the sponge itself synthesize directly these acids, and they are taxonomic and trophic markers.
