“…Although time-series data are arduous to collect, clearly much is gained by making such studies. At present there are few such studies (Buzas et al, 1977(Buzas et al, , 2002Scott and Medioli, 1980b;Murray, 1983Murray, , 2003Basson and Murray, 1995;Hippensteel et al, 2000Hippensteel et al, , 2002Murray and Alve, 2000) and these are mainly confined to single environments such as intertidal and shallow sub-tidal. Murray (2003) states there is a need for further studies in a range of environments to provide estimates on the size of local species pools and to provide baseline data to compare future long-term environmental changes.…”

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.

“…Results of analysis of the total living population (standing crop) are similar to those of the most abundant species, only overall periodicity is significant at the 95% level. Similarly, multivariate analysis (all 19 species considered simultaneously) using the same hypotheses showed only station differences and overall periodicity to be significant (Buzas et al, 1977).…”

“…In Jamaica, West Indies, Buzas et al (1977) sampled two Thalassia habitats, one in a back-reef fl at at a depth of less than 1 m and the other at about 3 m depth in Discovery Bay. Each habitat was sampled with four replicates each month from November 1969 to October 1970.…”
