Hello Klaus's daughter has reported on Facebook that sadly Klaus has passed away. One of the leading lights of British diatom studies is gone but has left a very fine legacy. Some of my most treasured

I am working on a key to morphological groups of diatoms. Here is the latest revision [1]. As VanLandingham said, "There is no such thing as taxonomic truth." Rob [1] https://drive.google.com/drive/fo

Apologies; further to my last, there are two further specimens, as attached, in case that helps. Best regards Robin Lewando From: diatom-forum@groups.io <diatom-forum@groups.io> on behalf of robin lew

Hi Robin, I last bought Naphrax from Brunel in the UK in 2017, they have it for sale still (although not cheap). They sell an export version that is not diluted with toluene, so I got that. I live in

Hello group. The attached photos are of two diatoms from the sediment surface on the shallow edge of a freshwater lake in lowland West Cork ,Ireland. A most distinctive shape but I am drawing a blank

I am deeply grieved to hear of the death of Klaus Kemp. He and I corresponded a good deal over the years, and I purchased many slides from him -- all exquisitely beautiful. He was also very good at di

This Web Academy talk considers the population dynamics of a species of the centric genus, Actinocyclus. Many interesting aspects are covered such as molecular data, the ways in which data is collecte

Hello. Whilst selecting images to help in identifying fossil diatoms I have been finding at 6.50 and 6.49 m depth quite a few of these triangular... well, I believe they are diatoms. They seem to fit

Hello Group, The talk given April 12 by Kalina Manoylov is now online. Titled "Species diversity and community dynamics of diatoms in the Savannah River estuary", it covers the 50 year history of cons

Hi Group, Some of my E C P Bone slides do not have the species identified and in some, neither the genus. One marked only "From Malaya 1962" is one such with no indication of genus. Nice slide prepare

Hi. This is a sample of a selection of the smaller diatoms I am finding. These are from 6.53 m depth, i.e c. 16ka. I have included several images at different foci of the two centric specimens. The se

After nearly 5 years, I think I have identified who made and used these keeper/sorter slides! (Original post here https://groups.io/g/diatom-forum/message/3869 ) I could not find the picture I posted

I don't know if anybody wants to take on the Diatoms of the Arid Southwest, but if somebody does, please contact Dr. Bundy. Somebody might want to archive the database so the records are not lost. I h

I found the quote by Albert Grunow (in the posting from a few days ago) during nametracing Berkeleya rutilans through time. Humbling stuff. To lighten the moods after this heavy stuff, I added a bunch
