“…Similar differences between live and dead assemblages due to the dissolution of calcareous species have been noted in other studies (e.g. von Daniels, 1970;Goldstein and Harben, 1993;Goldstein et al, 1995;Collins, 1996;Watkins, 1998, 1999;Edwards and Horton, 2000;Horton et al, 2005;Culver and Horton, 2005). With respect to sea-level studies, Edwards and Horton (2000) noted during a study of Arne Peninsula, South England, that reconstruction techniques performed reliably in the high marsh zone where agglutinated foraminiferal species are dominant.…”

We have collected live and dead foraminiferal times-series data at 2-weekly intervals for a 12-month period from the intertidal zone of Cowpen Marsh, Tees Estuary, UK. The data from the 689 samples show profound differences between live and dead assemblages, although assemblages are dominated by just three species, Haynesina germanica, Jadammina macrescens and Trochammina inflata, which represent over 70% of the assemblage. The cumulative increase in species of most environments approximates to a lognormal or log series. None of the datasets show a broken stick pattern. The cumulative maximum number of species, which represents the species carrying capacity of the environment, is recorded earlier in the life assemblages than the dead counterparts. The dead assemblage of Cowpen Marsh is found to have a higher abundance (435 compared to 163 individuals/10 cm 3 ) and number of species (52 compared to 28) than its live counterpart because the dead assemblage represents many generations added over a long period of time. In contrast, some species are recorded in the live dataset that were not found in the dead assemblage, indicating the dead record is either incomplete (e.g. taphonomic change) or inadequately sampled.We investigated the influence of patterns in cumulative increase on dead assemblages for sea-level reconstructions through the development of foraminiferal-based transfer functions. The cumulative transfer functions suggest that the performance improves during the first six sample intervals of the time-series dataset with reconstruction differing by 1.2 m and remains constant thereafter.

“…Other common species living on these mudflats included Elphidium excavatum (Terquen), Ammonia tepida (Cushman) (=Ammonia 'T7' of Hayward et al 2004), Psammophaga sp., and Ovammina opaca Dahlgren (Fig. 3 The primary difference between the in situ assemblages at these 2 mudflat sites was that the dead assemblage (consists of empty tests) at the Light- Gupta & Kilbourne 1976, Goldstein & Harben 1993. Overall, species richness, particularly of the dead assemblage, was higher at the exposed Lighthouse site (27 species of which 10 were alive) than at the protected mudflat at Chocolate (14 species of which 10 were alive).…”

“…The Lighthouse mudflat is bordered by a large salt marsh that includes both a broad low marsh, dominated by the halophyte Spartina alterniflora Loisel, which is typical of Georgia salt marshes, and diverse high marsh habitats (e.g. Goldstein & Frey 1986, Goldstein & Harben 1993. The second mudflat, here referred to as the 'Chocolate mudflat ' (31°30.166' N, 81°15.293' W), is located in the tidal estuary of the Mud River, and is adjacent to the historical site on Sapelo Island known as Chocolate.…”

“…These features are in contrast to the attached, immobile, trochospiral epifaunal species (e.g., Cibicides lobatulus, Rosalina spp; see Kitazato, 1988) which are typically planoconvex. Although A. beccarii and T. inflata have been recorded in small numbers in epiphytic communities (Matera and Lee, 1972), they are most commonly found living within the sediments (e.g., Steineck and Bergstein, 1979;Langer et al, 1989;Goldstein and Harben, 1993;Ozarko et al, 1997) and none of them seems to live in symbiotic association with algae or algal chloroplasts (Knight and Mantoura, 1985). Both in culture and field studies, Langer et al (1989) observed A. beccarii to dig itself into the sediment surface with a cork-screw movement, and the direction of the rotation corresponds to the growth direction.…”
