The truth about diatoms should be accessible to everyone, in cyberspace and beyond!
From the first time I got a glimpse through a 1.4 NA oil immersion objective lens on a Zeiss microscope, I have been obsessed with diatoms. I think that if people could see diatoms, they would be just as obsessed as me. Developing a website for taxonomy and ecology is my effort to get kids, students, professionals, drifters and old folks involved, engaged, and advancing the field more than we thought possible. Biologists have the ability and the responsibility to address the crisis in loss of biodiversity and issues of environmental change.
