OLI Grant: Sub-millimeter life positions of magnetotactic protists in reducing salt marsh sediments


Grant Funded: 2004

Documentation of the life positions of microorganisms on the millimeter- to micron-scale can provide much information relevant to the biogeosciences.  For example, life position associations between prokaryotes and eukaryotes provide physiological information as well as information of geochemical heterogeneity and cycling. The objective of this Ocean Life Institute proposal is to refine a presently-existing life position method with the routinely-used fluorescent in situ hybridization (FISH) technique to identify targeted microorganism species or groups.This method development will be done using readily available field collections near Woods Hole, but will ultimately provide a method for application in a variety of biogeochemical settings and for additional microorganisms including prokaryotes and eukaryotes.
