About the Taxonomy
The taxonomy used in Pachyderm is a conservative reflection of what is being used in general biology textbooks. The goal is to help students learn the basics of taxonomy. All you taxonomists out there itching to write in and say that this or that group has been renamed please hold your advice as we will get around to changing it when the consensus has reached the point that the textbooks WE use have changed. Remember, taxonomy is constantly changing, and we are trying to give our students an exposure to the taxonomy that will help them as they search the literature. That being said, if anyone sees an image which we've misidentified, we'd be happy to hear about it.
Pachyderm Web is an outgrowth of the Pachyderm Program, written by Dave McShaffrey. All images copyrighted by Dave McShaffrey and Tanya Jarrell. The original Pachyderm software was supported by NSF Grant DUE- 9750553, and development of Pachyderm Web was supported by a TIG grant from Marietta College in turn supported by a US Department of Education Title III grant.
