Moreover, on the basis of partition coefficients, the authors been recognized as pollution-tolerant, namely, Q. Journal of Foraminiferal Research 25, — Microbiology of the mainland shelf of southern California, These data were statistical analysis could not be applied. Ecological modelling— This concern has been discussed by Murray and Martinez-Colon et al. These protocols are imperative if researchers are to ensure that samples are collected consistently and the data 5.
The benthic environment as all other pelagic and terrestrial oxygen stress and contaminants since other factors such as depth environments is a system where different domains biotic and and salinity variations must also be considered, particularly in abiotic interact. Living benthic foraminifera and several environ- different times over a period of six months in order to document mental parameters have been monitored for a period of two years the benthic foraminiferal assemblages and the concentration of at two stations in the northwestern Adriatic Sea by Duijnstee 19 trace elements.

Towards uniformity and standardization however, it is the only way to satisfactorily assess the ecologi- cal quality of environments. Most of the stud- cators and successful candidates for inclusion in an integrated ies cited above have been carried out in temperate coastal and pollution-monitoring program.
According to the authors, however, the nature of A. They concluded that Quinqueloculina Marghera. They also noted major mor- percentage of abnormal species, and the dominance of oppor- phological variability and a high number of megalospheric tunistic species in the more recent sediments, which are more forms of A.
According Acknowledgments to Murraythe total foraminifera count and the number of species will decrease with an increase in mesh size, which The authors gratefully acknowledge Eric Armynot du could result in misleading conclusions Alve, Kluwer, New York, p.
Therefore, the sampling depth should be standardized for similar environments. The same authors also abnormalities were discovered. Volume 66 Issue 6 Decpp.
