Abstract
This paper quantifies the spatial distribution of zooxanthellae (ZX) and zoochlorellae (ZC), two
algal symbionts common to the temperate anemone, Anthopleura xanthogrammica, in relation to
shore height. Anemones in tidepools and crevices had varying algal proportions: .0.90 ZC
(green anemones), 0.10 to 0.90 ZX (mixed), and .0.90 ZX (brown). Brown anemones are
primarily found in the high intertidal and the upper region of tidepools. Mixed anemones are most
common at intermediate shore heights and green anemones are exclusive to the low shore and at
increasing depth in tidepools. Microhabitat was also important to algal proportion, as anemones in
crevices had greater proportions of ZC than anemones in tidepools at the same shore height. In a
reciprocal transplant experiment, A. xanthogrammica were moved between high and low shallow
tidepools. All anemones moved from a low to a high tidepool exhibited a shift from ZC to ZX
populations, while the anemones transplanted from high to low tidepools maintained ZX
dominance. This is the first documentation that field algal populations can shift from ZC to ZX in
Anthopleura. The field survey and transplant study results support the hypothesis that the relative
abundance of ZX and ZC in A. xanthogrammica is influenced by the environmental gradient
associated with shore height and microhabitat.
