Living in a contaminated estuary - behavioral changes and ecological consequences for five species

  1. 1. Living in a Contaminated Estuary: Behavioral Changes and Ecological Consequences for Five Species Wang Chao 30 Sep. 2013
  2. 2. Publishing Authors: Judith S. Weis, Lauren Bergey, Jessica Reichmuth, Allison Candelmo Source: BioScience, Vol. 61, No. 5 (May 2011), pp. 375-385
  3. 3. Topic 1. One side is from the estuary pollution. 2. The other side is from the effect to species by pollution.
  4. 4. Estuary Pollution Urban areas often grow up around estuaries. Industrial development often leaves a legacy of pollution in these areas. The Georges River Estuary http://www.georgesriver.org.au/Estuary-Management-Plan.html
  5. 5. Estuary Pollution http://estuaries.noaa.gov/Estuarylive/VideoGallery.aspx?ID=43 http://estuaries.noaa.gov/Estuarylive/VideoGallery.aspx?ID=33 First,let’s watch a video.
  6. 6. After watch the video Do you think what things are the major sources of pollution to the estuary? Metals, oils, toxic organic compounds such as (PCB)… and high levels of nutrients...... Estuary Pollution Note: PCB stand for polychlorinated biphenyl
  7. 7. Main Topic--Behavioral Changes This paper focus on the feeding behavior and predator-prey relations in contaminated and clean estuaries and examining population and community-level consequences.

  10. 10. Questions and discussion Feeding habits and diet, physiology, body size, and reproductive rate affect how a species responds to contaminant stress, but all of those traits can themselves be altered by contamination. Plasticity of traits, especially feeding habits, is important in a changing environment.

  16. 16. Questions and discussion Are organisms at higher trophic levels more likely to be affected? Reynolds PL, Bruno JF (2012) Effects of Trophic Skewing of Species Richness on Ecosystem Functioning in a Diverse Marine Community. PLoS ONE 7(5): e36196. doi:10.1371/journal.pone.0036196
  17. 17. Questions and discussion Are certain taxonomic groups more likely to be successful under contaminant stress? Different special have different tolerance to the contaminated estuary. For example, Bergey et al. (2007) pointed that one trait of crustacean that may promote their greater success could be the ability to move contaminants into their exoskeletons before molting.
