Assignment:

Please describe in paragraph format at least three kinds of biochemical adaptations that an organism would have to have in order to thrive in the following environments.

You will need some online research about the habitat but use the lecture to speculate on the cell membrane/wall/protein/genome/internal structures.

  • The dead sea.
  • The Savannah River Superfund Site.
  • The Vostok lake.
  • A black smoker (hydrothermal vent).

Symbiosis Speed Dating

Please SPECULATE (don't google, only book and lecture) on a microbial mutualistic symbiosis that could "resolve" the issue. No species names needed. It has to have two co-evolved partners (symbiosis) and some nutrient exchange that is mutually beneficial to the organisms (mutualism). Pick three.

  1. A volcano erupted stranding a group of fish-eating lizards far away from streams and lakes. They begin to eat fruits, roots, and grasses but cannot digest them very well. What symbiosis would help these lizards?
  2. A coral reef fish is finding fewer and fewer sponges to eat because of climate change. The only sponges that are abundant are ones with a toxic nitrogen compound to help protect it from predators. What symbiosis could help these fish?
  3. A paper mill is built upstream of a healthy pond. This causes algal blooms that eat up all the oxygen in the water. What symbiosis could help the fish in this ecosystem?
  4. UVR exposure is related to climate. With changes in conditions, a group of trees is experiencing unusually high UV exposure for much longer parts of the season causing stress and tumors. What symbiosis could help these trees?
  5. Ciiy pigeons are increasingly exposed to sulfur dioxide in polluted city air. They begin to develop lesions in their respiratory system. What symbiosis could help these birds.
  6. A group of 100 beetles in carried in a crate of fruit from Egypt to Brazil. They are used to being dry all the time and in Brazil they become covered with toxic mold growing on the moisture on their exoskeleton. What symbiosis would help these beetles?
