... of Archaias angulatus , both in hospite and in cytoplasm extracted from the host shell, across a range of temperature conditions (4.4–33.9°C) using pulse amplitude modulated chlorophyll fluorometry and chlorophyll a measurements. Typical mean yields (F v /F m ) for symbionts in hospite were 0.6–0.7...

...Kazuhiko Fujita; Pamela Hallock Abstract Habitat preferences of epiphytic foraminifers, particularly Archaias angulatus and Sorites orbiculus, were studied in a mixed macroalgalseagrass bed in Florida Bay near Long Key. Ten common plant species with different growth forms were sampled. On all ten...
