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.
