| Outline of Final Research Achievements |
Xenophyphores are giant, unicellular protists that flourish on the deep-sea floor in all the word’s oceans. Their large and complex tests accumulate toxic metals from the water column, but also attract a wide variety of organisms, including isopods, polychaetes, mollusks, and echinoderms. This research was aimed to establish the relevance of xenophyphores as bioindicators of deep-sea ecosystem health and whether they can be used to assess environmental pollutant concentrations and local/regional species diversity. Unfortunately the project has been cancelled due to a lack of fresh specimen samples.
