Imagine that one diatom assemblage has 20 species and another has 25, but the more species rich assemblage also has more diatoms counted.A fair comparison of the richness of each assemblage can onl…| Musings on Quantitative Palaeoecology
In any analysis, there are a series of steps: data importing, cleaning, analysis, creating figures, and then putting it all together in an manuscript. Very often, some of these steps are time consu…| Musings on Quantitative Palaeoecology

By coincidence, days after I wrote about the apparently very low midge counts in Hiidenvesi, the authors published a correction. Erroneous information considering Chironomidae and Chaoboridae accum…| Musings on Quantitative Palaeoecology
Last week I gave a course on R for palaeoecologists covering data handling using tidyverse, reproducibility and some some ordinations and transfer functions. One of the exercises was to download so…| Musings on Quantitative Palaeoecology
