Comparing Sea Anemone Diversity in the Arctic and Antarctic Justin Buck and Daphne Fautin Ecology and Evolutionary Biology, University of Kansas Natural History Museum (http://web.nhm.ku.edu/inverts/Image/)
What is a Sea Anemone? • Benthic marine animal in the order Actiniaria • Found at all depths in every ocean in the world (http://web.nhm.ku.edu/inverts/Image/)
Benthic Animal Diversity Trends Number of Recorded Benthic Species for Certain Groups in Arctic and Antarctic (Barry & Grebmeier, 1991) • “The Antarctic has much higher species richness yet lacks the ecological diversity of the Arctic” (Dayton, et al., 1994: p. 90)
Hexacorallians of the World • http://hercules.kgs.ku.edu/hexacoral/anemone2/index.cfm • Website created in Daphne Fautin’s lab
Preliminary Data • More diversity is shown in Arctic than Antarctic • What will normalizations do to this data?
Normalizations • Area: • Arctic and Antarctic Oceans • Effort • Number of publications • Number of Expeditions (http://www2.kah-bonn.de/1/16/0e.htm) (http://hercules.kgs.ku.edu/Hexacoral/expedition/challenger_1872-1876/challenger.html)
Area Normalization • Used data in latitudinal ranges from 50º-90º North and South • The Arctic Ocean is about 1/4th the size of the Antarctic Ocean (Garrison, 1996) (http://www2.kah-bonn.de/1/16/0e.htm)
Publication Normalization • Relationship of genera per publication and species per publication
Expeditions Normalization • There have been 4 times more expeditions to the Arctic than to the Antarctic
Summary of Normalizations • Area • Arctic greater diversity • Publications • Arctic species greater diversity • Antarctic genera greater diversity • Expeditions • Antarctic greater diversity
Conclusion • The Arctic seems to be much more diverse than the Antarctic
Further Study • Compare diversity of sea anemones in every ocean in the world • Compare the diversity at different depths as well
