This research article from BMC Evolutionary Biology (2007) presents a study of the biogeography of certain protozoa. This resource might be of interest for both the methodology and the results of the study. In order to test the hypothesis that all protozoa are globally distributed, the authors obtained DNA sequences for a rapidly evolving gene from several locations around the world. The methods used, including steps taken to avoid pitfalls common in such studies, are described in detail. In discussing their results, the authors addresses possible weaknesses in the data. This paper should be accessible to advanced undergraduate as well as graduate students and teachers.
