Brian, Edison, and Kevin are lumberjacks who live next to a forest that is open to logging; in other words, anyone is free to use the forest for logging. Assume that these men are the only three lumberjacks who log in this forest and that the forest is large enough for all three lumberjacks to log intensively at the same time.

Each year, the lumberjacks choose independently how many acres of trees to cut down; specifically, they choose whether to log intensively (that is, to clear-cut a section of the forest, which hurts the sustainability of the forest if enough people do it) or to log nonintensively (which does not hurt the sustainability of the forest). None of them has the ability to control how much the others log, and each lumberjack cares only about his own profitability and not about the state of the forest.

Assume that as long as no more than one lumberjack logs intensively, there are enough trees to regrow the forest. However, if two or more log intensively, the forest will become useless in the future. Of course, logging intensively earns a lumberjack more money and greater profit because he can sell more trees.

The forest is an example of a_________ (A club good, A private good, A public good, A common resource).

Because the trees in the forest are________ (Excludabel, Nonexcludable) And ________ (Rival in consumption, Nonrival in consumption).

Depending on whether Edison and Kevin both choose to log either nonintensively or intensively, fill in Brian's profit-maximizing response in the following table, given Edison and Kevin's actions.

                          Edison’s and Kevin’s Actions

                                  Log nonintensively                      Log Intensively

Brian’s Profit Maximizing Response (Log intensively or Log nonintensively (Intesnively or Nonintensively)

Which of the following solutions could ensure that the forest is sustainable in the long run, assuming that the regulation is enforceable? Check all that apply.

  1. Outlaw intensive logging.
  1. Develop a program that entices more lumberjacks to move to the area.

  1. Convert the forest to private property and allow the owner to sell logging rights.

Please explain things in the correct order so that it is easy to understand.

2) Biofilms and other multicellular behaviors a) Recall that bacteria (and archaea) exhibit both transient and permanent multicellularity. How does these behaviors benefit bacteria? What are the costs? b) What kinds of environmentts seem to favor multicellular behaviors? Recall our discussion in the lecture – two that we discussed at length were mechanical antibiotic & chemical resistance and evasion of predators. c) Explain quorum sensing, especially the details we discussed with the Vibrio fischerii example. d) Compare and contrast incipient vs patterned multicellularity, and fit the examples of Bacillus subtillis, Myxococcus xanthus, and Streptomyces spp. into your explanation. How do these examples challenge our notions of the divide between single-celled and multicellular organisms? e) What is the microbiome? What are some of the implications for human health?
