BiologyBase is the work of R Hole, Jr. I've been working on various versions of this site since 1995, and continue to add and refine information provided here.

I am a biologist, writer and artist and have lived, taught and studied across North America and from southern Mexico into Canada.

BiologyBase is self-funded, and does sometimes get ignored when eating is a priority. If you like what you see looking around here and would like to see more, please consider sending a donation via paypal through the link below, or shop the recommended books and other stuff either through the Book Depository (free shipping worldwide) or through the Amazon links.

Thanks for visiting, I hope you enjoy the site and get some use from it.
