... 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...

...Paul O. Knorr; Lisa L. Robbins; Peter J. Harries; Pamela Hallock; Jonathan Wynn Abstract A common, but not universal, effect of ocean acidification on benthic foraminifera is a reduction in the growth rate. The miliolid Archaias angulatus is a high-Mg (>4 mole% MgCO 3 ), symbiont-bearing...

...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...

... species with porcelaneous tests and those with calcareous hyaline tests. For this study, a video camera with a microscope attachment was used to record chamber formation in Archaias angulatus . Detailed study of the recording revealed previously undescribed transitional stages prior to calcification...
