Why loss matters: Reply to the comments of Festi and others on 'A quantitative comparison of microfossil extraction methods from ice cores' by Brugger and others (2018).

Furthermore, the differences in pollen percentages between the centrifugation-based methods (FESTI, EICHLER) compared to the filtration- and evaporation-based methods indicates a clear variation in pollen composition (pollen percentages), which is independent from marker-based concentration estimates. Thus, as Festi and others ([10]) correctly repeat, the method differences have important implications for the interpretation of pollen records with a preferential loss of vesiculate pollen when using centrifugation-based methods, which is one of the fundamental conclusions in our method comparison (Brugger and others, [3]). A comparison of pollen extraction methods confirms dense-media separation as a reliable method of pollen preparation. [Extracted from the article]
