Investigating Current Research Problems

Scientists exchange ideas and information through scientific journals. Thousands of these exist, many in very specialized fields. Conservation Ecology is an important example of a new variety of scientific journals: e-journals, which you can access on the Worldwide Web. This journal includes research articles, debates, discussions, and comments from a variety of well respected and active ecologists, and it covers topics that are very current. Go to the Conservation Ecology at http://www.consecol.org/Journal/ and look at the most recent issue.

1. Review the table of contents: what are the topics that ecologists are concerned about today?

2. Look at one of the articles in detail. How does the tone of the article reflect some of the ideal approaches of science outlined in chapter 1 (hypothesis testing, cautious inspection of evidence, objectivity)?

3. What kinds of data (or other evidence) are presented in support of the author's arguments?

4. Some of the articles are debates about a particular topic. Find one of these and identify the positions on either side of the debate: what is the question they are debating? describe two (or more) opposing views on the question.
