  1. Climate Change + Life Histories Group A25 Biology 1510 Alejandra Arango, Ashley Medlock Ryan Evans, John Durham, Jeremy Carmack

  2. Introduction What we will be discussing. Cause of climate change Effect of climate change on arctic marine life Case study - Apherusaglacialis Future consequences of climate change Figure 1: http://www.sciencedaily.com/releases/2012/09/120913173030.htm#.UFOdjtawXDA.twitter

  3. Why is this happening? The cause of climate change Burning fossil fuels introduced to carbon cycle Greenhouse effect Expansion of Hadley Cell Warming of the poles Figure 2: http://www.earth-policy.org/indicators/C52/carbon_emissions_2010 Figure 3: http://www.theresilientearth.com/?q=content/wetter-world-during-eocene

  4. What is happening? The effect of climate change on arctic marine life Increase in density gradient Primary consumers not receiving proper nutrients Figure 4: http://www.bio.utexas.edu/faculty/sjasper/Bio213/aquahab.html

  5. Case Study Apherusa glacialis Figure 5. Nemohypothesis – downward vertical migration Pelagic phase Ascend during spring algal bloom http://rsbl.royalsocietypublishing.org/content/early/2012/09/04/rsbl.2012.0517.full.pdf Nemo: http://images.catchsmile.com/wp-content/uploads/2011/04/Nemo.jpg

  6. Impending consequences How climate change will affect future marine life. Restructuring of food web Escape of methane gas in the atmosphere Major fishing areas decrease in size Figure 6 http://oceansnorth.org/climate-change

  7. Conclusion. Take home message. NPP decreases Species richness declines Organisms adapt or die Figure 7 http://www.worldatlas.com/webimage/countrys/polar/arctic.gif
