In natural populations of the intertidal copepod Finistra elegans, variation exists for two color morphs: a light brown form and a light green form. A student estimates the frequency of the light brown copepod to be 12%, 15%, and 17% over three consecutive years. Over the same three-year period, the population remained stable and no discernible changes occurred in the abundances of other intertidal species.
(a) Provide five explanations for why the frequency of the light brown copepod has apparently increased. (Please use a few sentences for each explanation.)

(b) What evidence would be required to support an adaptive basis for the increase in frequency of the light brown copepod? Briefly describe one experiment that could provide such evidence.

I have an essay due on Friday and need help getting started with some ideas. PLEASE HELP ME!!!

    For researching:

    You may have to search and research, but once you learn some good sources and methods, you should have success. In addition to searching on the Internet, you also need to make best friends with the reference librarian(s) in your local or college library. Libraries these days subscribe to enormous research databases, and they are often more useful than Internet searches. Ask your librarian if you have access to EBSCOHost -- it has several databases within it, including a huge one for academic research.

    For Internet searching:
    At this webpage, you can go immediately to the search sites (first three columns across the top) -- or even better you can scroll down until you see the section called HOW TO SEARCH THE INTERNET. Those are the links to start with. You'll not only learn how to come up with good search terms, but also how to evaluate the webpages you get as results. Some will be good and others will be garbage. You need to know how to tell the difference.

    My favorite way to search is to go to Google's advanced search page http://www.google.com/advanced_search?hl=en and put my search words or phrases into the first or second search box (either "all the words" or "exact phrase"). Another is to start out at http://scholar.google.com. However, there many other strategies for searching you can use, and the HOW TO SEARCH THE INTERNET section will help you best.

    For writing:

    Follow the writing process, whether you're writing for science, history, English, or whatever:

    Prewriting: Brainstorm, research, plan, outline, thesis statement

    Writing: Write first draft by starting with section II of your outline; write the introduction after the body of the paper is written; write the conclusion last.

    Polishing: Revise, concentrating first on the body of the paper, then the intro, then the concl (revision = making sure ideas are logical and sequential and support your thesis); proofread (spelling, grammar, usage, etc.)

    Do you have a thesis yet? Have you done your brainstorming (and maybe research) yet? Have you written an outline?
