Diatom of the month - March 2018: Afrocymbella barkeri

by Heather Moorhouse*
The tropical diatom genus Afrocymbella has only 12 known species, all of which are found in the African Rift Valley lakes1. They have been observed both free-living in the water column and attached to rocks and plants, and are solitary or colonial1. One such species is Afrocymbella barkeri Cocquyt & Ryken sp. nov. (19.9-63.8 ┬Ám) (Fig. 1), a newly described diatom found in Lake Chala1 (Fig. 2), a tropical crater lake that lies directly on the border of Kenya and Tanzania, just south of the equator (Fig. 3). 
This species was named after Prof. Philip Barker whose seminal work on diatoms in the East African Rift valley lakes has helped understand past climate and environmental change in the region. Afrocymbella barkeri is common at the end of the dry and windy season in Lake Chala, which corresponds to the northern hemisphere summer. The summer winds mix the lake water column and cause nutrient-rich deep water to rise to the surface, providing the nutrients that f…

Results of the ISDR/IUBS Student Travel Award

Image
The results of the Student Awards are up! Finally, 49 young Diatomists have taken part contesting for 8.800 € granted by the ISDR and IUBS. The awards will go mostly toward travelling fees, and include the inscription fee to the International Diatom Symposium in Berlin (25-30th of June).

If you have been awarded with one of the 25 awards given to Young Diatomists, we would like you to contact us to tell us about your experience. Don't forget to prepare your talk! :)

Congratulations to the winners!

Now some statistical data: from the 25 awards, 17 have gone to female Young diatomists.
Most Student Travel Awards have gone to Doctoral students (18). Followed by Postdoctoral researchers (5) and Master students (2).


6th Polar Marine Diatom Workshop

The Polar Marine Diatom Workshop is now open to state interest. It will take part at the idyllic Iowa Lake Lab at Milford, Iowa (USA) in August (6-10).

As Beth Cassie states in her email: "The Polar Marine Diatom Workshop is an interactive workshop that combines longer, microscope-based taxonomy and morphology sessions with shorter research talks and posters. We aim to have an integrated, participatory group of highly-experienced senior-level, mid-career, and early career scientists combined with graduate and undergraduate students. The workshop is focused on diatom taxonomy and paleoceanographic applications of diatoms from both polar regions."
