APPLICATIONS OF THE ARCTIC OSTRACODE DATABASE (AOD) TO SPECIES ECOLOGY AND PALEOENVIRONMENTAL RECONSTRUCTIONS (Invited Presentation)
The AOD is used to investigate modern ostracode biogeography, regional community structure and ecology. In addition, fossil occurrences of a species with known modern environmental tolerances and ecology can provide a basis for the reconstruction of Cenozoic environments. Therefore, the AOD can provide a better understanding of how the Arctic Ocean has been affected by, and perhaps influence climatic and oceanographic change during both the Common Era and deeper geologic time (e.g. Quaternary and Pliocene).
This talk will address how the AOD can be used to address questions such as:
-- How is contemporary climate change affecting benthic ecosystems? Specifically, have ostracode assemblages changed over the last ~40 years?
-- What factors explain geographic differences in ostracode abundance and diversity?
-- Can the AOD be used to create temperature envelopes for modern Arctic and subarctic ostracode species environmental ranges and applied to fossil ostracode assemblages to approximate past ocean temperatures from the early Pliocene though the Pleistocene?
