When does environmental variability become environmental change? The proxy record of benthic foraminifera
When does environmental variability become environmental change? The proxy record of benthic foraminifera
There are three possible approaches to investigating environmental change using organisms as proxies: comparison of spatial surveys from different time periods, time-series studies, and high resolution studies of cores. Because they have a preservable shell and are abundant, benthic foraminifera are the best meiofaunal group for giving a proxy record of past marine and marginal marine environments. Through the analysis of: changes in abundance of marker species; the introduction of new species or serious loss of previously existing species; changes in species diversity, dominance and abundance which extend well outside the established limits of variability; it is possible to document the extent of environmental changes that have taken (or are taking) place.

Abstract
There are three possible approaches to investigating environmental change using organisms as proxies: comparison of spatial surveys from different time periods, time-series studies, and high resolution studies of cores. Because they have a preservable shell and are abundant, benthic foraminifera are the best meiofaunal group for giving a proxy record of past marine and marginal marine environments. Through the analysis of: changes in abundance of marker species; the introduction of new species or serious loss of previously existing species; changes in species diversity, dominance and abundance which extend well outside the established limits of variability; it is possible to document the extent of environmental changes that have taken (or are taking) place.
