What is Fragilaria koensabbei and does it matter what it is called? (Meta)barcoding and the science of taxonomy Commentary is provided on the use of barcoding and metabarcoding in diatom studies and its broader relevance to the principles of taxonomy. The claims that taxonomy, however it is performed, is time-...

"The claims that taxonomy, however it is performed, is time-consuming and that it requires extensive expertise, due to a constantly evolving taxonomy, are questioned as good, even useful, criteria by which to judge a science" by

Gutting USAID threatens billions of dollars for U.S. farms, businesses U.S. businesses that sold goods and services to USAID are in limbo, including American farms dealing in rice, wheat and soybeans.

US farmers sold $2 billion of food to USAID. Not any more.

- $340M of purchases/shipments are now paused. Over 680,000 tonnes.
- Food stranded in Houston
- Aid stopped in transit.

The world’s poor starving, food rotting & US farmers screwed.

I have been turning a bunch of my own drawings (rendered from SEM images) of diatoms that I post onto Redbubble shop (www.redbubble.com/people/Diato...) as coloring pages. Feel free to use them for your outreach. Here's a marine diatom #Arachnoidiscus.

DiatoViz provides templates for plotting in R DiatoViz provides silhouettes of diatoms to be plotted in graphs in R. The use can be made either by the scientific name or by the OMNIDIA code.

The #DiatoViz package provides a simple function to add silhouettes of #diatoms to plots generated #ggplot2. Great work by @junqueiragaabi.bsky.social
