CHANGES IN THE ULTRASTRUCTURE OF SYMBIOTIC ZOOXANTHELLAE (SYMBIODINIUM SP., DINOPHYCEAE) IN FED AND STARVED SEA ANEMONES MAINTAINED UNDER HIGH AND LOW LIGHT1

Abstract: The ultrastructure of symbiotic dinoflagellates (Symbiodinium sp., zooxanthellae) in the sea anemone Aiptasia pallida Verrill was examined in well‐fed or starved (up to 120 days) anemones maintained under two light levels (5 and 50 μmol · m−2· s−1). Cell size of zooxanthellae was not affected by feeding history; however, both light and feeding history affected the relative cell volume of chloroplasts, lipids, and vacuoles. Stereological analysis of transmission electron micrographs showed that algae in low‐lig… Show more

“…One hypothesis is that the host could limit symbiont growth, either by restricting the supply of nutrients or by actively "blocking" symbiont mitosis (see the previous section), thus generating a surplus of photosynthetic carbon for release (105,267). It is important to note, however, that nutrient limitation may cause carbon storage rather than release in symbiotic dinoflagellates (78,251), as it also does in free-living microalgae (375).…”

“…Potential sources include zooxanthellae released by cnidarians (Steele 1977, Hoegh-Guldberg et al 1987, HoeghGuldberg & Smith 1989, Stimson & Kinzie 1991, Davy et al 1997, Maruyama & Heslinga 1997, those excreted by fish (Muller-Parker et al 1996, Augustine & Muller-Parker 1998, and possibly populations in the benthos (Carlos et al 1999). Given that infection rate is correlated to zooxanthella concentrations (Montgomery & Kremer 1995, Kinzie et al 2001), a comparison of the rates of zooxanthella acquisition under known zooxanthella concentrations with that observed in situ provides a rough estimate of zooxanthella abundance in the field.…”

“…Algal toxins may speed coral calcification during nutrient shortages. Nutrient shortages freeze zooxanthellae in the G1 phase of the cell cycle (Muscatine et al 1989, Muller-Parker et al 1996, Smith & Muscatine 1999, Wang et al 2008; Fig. 6a), where dinoflagellates are often most toxic (Pan et al 1999, Taroncher-Oldenburg et al 1999, Guisande et al …”

“…6a), they can take coral nutrients as they leave, and they will likely die if they remain inside a bleaching coral (Dunn et al 2004). The coral may also evict the algae, if they become too toxic, and mainly produce lipids (Muller-Parker et al 1996).…”
