Acidification Tolerance in Aquatic Organisms Cluster 3: Living Oceans and Global Climate Change Elana Sanford, Sona Trika, Joey Uy, Michelle Hines
BACKGROUND CO 2 emissions & the keeling curve Trend in decreasing pH Carbonic acid Calcifying organisms The foundation of the marine ecosystem Little Echo Pond in Franklin, New York (“The Keeling Curve.”, 2013) (“Little Echo Pond”, 2013)
BRINE SHRIMP Procedures 100% mortality rate for acidic Can control salinity in body, but pH is different Support rare birds & clean bodies of water by absorbing bad chemicals (“Brine Shrimp.”, 2013) DUCKWEED Procedures Different levels of low pH lead to different mortality rates Thin waxy outer layer Major producer SEA SNAILS Procedures No movement Shut itself off from outside in protective shell Eat soft algae reducing turbidity (McClung, 2012) (Schursastro, 2009) (Flatabø, 2005)
Procedures All died in low pH died, in medium low pH most died and fresh all survived Skin is a significant barrier Supports decomposition GUPPIES Procedures All exposed to low pH died while the rest survived Little outer protection Support frogs & eat algae (reduce turbidity) Procedures All survived Protective exoskeleton Scavenger GHOST SHRIMP (Aquatic Foods, 2013)(Petshrimp.com, 2013)(Krisp, 2013) BLACKWORMS
