What is this figure meaning? (Ecology -- Punctuated Equilibrium)

  1. Nov 2, 2015 #1
    1. The problem statement, all variables and given/known data
    As I reading this article I conflict with a problem, I never find the meaning of Figure 3(b).
    the paragraph below the figure illustrated it but I couldn't find what it want to say.

    every help will be a appreciated.

    2. Relevant equations

    3. The attempt at a solution

    Hi Binvestigator:

    The figure in your post and the paragraph describing it seem to me to be just as unclear as you found it. I tried to click on the link "this", but it failed to take me to the article. I edited the link address and the following seems to work better:
    This only shows the abstract. Unfortunately, I do not have access to read the article.

    You may find the following link of some use. It has a good discussion of the "punctuated equilibrium" concept.

    Presumably the figure is intended to be evidence either supporting or refuting this concept. Perhaps the text of the article would clarify this.

    Hope this helps.

    Hi Binvestigator:

    My town librarian was able to locate a copy of the article for me. I confess that after reading several pages near the Figure 3 you included in your post #1, I still am unable to understand what the horizontal lines in the figure represent, or what the authors are saying. My apologies. I wish you good luck in the course.
