  1. Climate Change and Life Histories Austin Jones Kaci Crawford Hanyang Li Yinzhou Yu

  2. Climate Change and Global Warming • What is Climate Change? • Reasons: • Population: CO2 and Fossil Fuels • High CO2 Infrared  Temp. Increase • Impact: • Geographic • Phenology • NPP Changes

  3. Effect of Ice-Free Summers for Apherusa glacialis • Article link: http://rsbl.royalsocietypublishing.org/content/early/2012/09/04/rsbl.2012.0517.full.pdf • Study: • Habitat (Food and Shelter) • Why affected by Global Warming • Changes to food sources and amount of habitat available

  4. Data/Results • Pelagic Phase • What/When it is • How it relates to A. glacialis • Geographic changes that cause it • Reproduction Period • In Relation with the Pelagic Phase

  5. Discussion • How does Global Warming affect A. glacialis? • COMPETITION • Food, Habitat, Mates • Disrupting the Ecosystem/ the Food Chain • Lowered NPP=Less Algae  More competition for food  Smaller population of amphipods  Less food for other organisms.

  6. Take Home Message • Global Warming affects more than just the temperature, it also affects the ecology of this organism and many others.
