Individual Research Efforts

 

               As part of the Water Team, we agreed that our research should be twofold.  One, we would all research the Amazon River as a whole, and two, to specialize in different areas of research, each focusing on one particular aspect of the Amazon River.  In doing so, I chose to focus my efforts on aquatic microorganisms and water pollution.

 

 



General Research

 

The following are titles from various journals with articles that I read that apply to our team’s research in general.  Click on “Summary” for more info.  If the article was in an e-journal, a link to the article may or may not be provided. 

 

 

 

  • Effects of river level fluctuation on plant species richness, diversity, and distribution in a floodplain forest in Central Amazonia. Summary

 

  • Unexpected results of a pilot throughfall exclusion experiment on soil emissions of CO2, CH4, N2O and NO in eastern Amazonia. Summary

 

  • Calculations of river-runoff in the GISS GCM: impact of a new land-surface parameterization and runoff routing model on the hydrology of the Amazon River. Summary

  • Property rights for fisheries at different scales: applications for conservation in Brazil. Summary

 

  • Chemical and physical denudation in the Amazon River Basin. Summary

 

  • Ion regulation in ion-poor acidic water by the blackskirt tetra (Gymnocorymbus ternetzi), a fish native to the Amazon River. Summary

 

 

 

 

 

 

Group Ideas

 

 

 

Monitoring

  • Precipitation
  • Mercury concentration
  • Sediment flow
  • Water levels
  • Health of Aquatic Biota

 

 

Group Change

 

 

With a few weeks left in the project, the Mission 2006 voted and as a whole decided to restructure the groups.  I was put into the “mining” group.  In these new groups, we were asked to submit characterizations and solutions that were compiled for the final webpage and document used for the final presentation.
