| preferential expulsion of dividing algal cells as a mechanism for regulating algal-cnidarian symbiosis. | a wide range of both intrinsic and environmental factors can influence the population dynamics of algae in symbiosis with marine cnidarians. the present study shows that loss of algae by expulsion from cnidarian hosts is one of the primary regulators of symbiont population density. because there is a significant linear correlation between the rate of algal expulsion and the rate of algal division, factors that increase division rates (e.g., elevated temperature) also increase expulsion rates. ad ... | 2000 | 11147708 |
