  • Re: Mystery diatom. Pseudauliscus?

    Hi, Dick. I put some more genera into the key [1]. Building these certainly makes me pay attention to the differences. Comments and corrections welcome. Rob

    Hello Dick,I would like to see the material you currently have on the tri-genera. It is definitely one of my weak areas.Charles On Thursday, July 2, 2015 6:53

    Hi Rob, OK, will do.  It will be a short while, as my generic "descriptions" will need some revision.  Your key is well designed, and looks quite easy to

Group Description

This group is a forum intended for those with a serious interest in the study of diatoms (Bacillariophyta). These microscopic organisms are famous for their ubiquitous occurrence in aquatic environments, and for the beauty of their silica-walled frustules (shells). They are among the most important primary food producers, and constitute the base of many important aquatic food chains.

Many of our members are interested in the taxonomy and evolution of the diatoms, while others have an interest in diatoms as esthetic objects. Others may have deeper interests in the ecology of diatoms. We see all of these interests as being fully compatible.

The purpose of the group is to facilitate: (a) communication among diatomists at all levels of expertise; (b) the sharing of images and data regarding diatoms; (c) the furtherance of education concerning diatoms; (d) discussion of diatom collecting techniques, and the cleaning and mounting of diatoms for observation with the light microscope; (e) assistance in identifying diatom specimens; and (f) other purposes that may arise as the group evolves. The group is moderated, the moderators being Dick Carter (United States), Leszek Wolnik (Ireland), and Raymond Hummelink (The Netherlands).

The image on our group homepage was made by Prof. Bill Dailey, and shows the diatom Kittonia elaborata (Grove & Sturt) Grove and Sturt. It is from the famous Late Eocene deposits of Oamaru, New Zealand.
