Effects of freshwater salinization on a salt‐naïve planktonic eukaryote community
Limnology and Oceanography Letters, Volume 8, Issue 1, Page 38-47, February 2023., 2023 Abstract Freshwater salinization is a widespread issue, but evidence of ecological effects on aquatic communities remains scarce. We experimentally exposed salt‐naive plankton communities of a north‐temperate, freshwater lake to a gradient of chloride (Cl−) concentration (0.27–1400 mg Cl L−1) with in situ mesocosms.

Conservation Biology, Volume 36, Issue 6, December 2022., 2022 Abstract River conservation efforts traditionally focus on perennial watercourses (i.e., those that do not dry) and their associated aquatic biodiversity. However, most of the global river network is not perennial and thus supports both aquatic and terrestrial biodiversity. We assessed the conservation value of nonperennial rivers and streams (NPRS) in

Environmental DNA, Volume 4, Issue 2, Page 363-384, March 2022., 2022 We assessed how the choice of bioinformatics algorithm (UCLUST, VSearch, DADA2, and Deblur) impacts the downstream biological conclusions that are drawn from eukaryotic 18S rRNA metabarcoding studies by using a low‐complexity and high‐complexity dataset. ASV algorithms produce more biologically realistic metabarcoding outputs, with DADA2 being the most

Factors shaping community patterns of protists and bacteria on a European scale
Environmental Microbiology, Volume 22, Issue 6, Page 2243-2260, June 2020., 2020 Summary Factors shaping community patterns of microorganisms are controversially discussed. Physical and chemical factors certainly limit the survival of individual taxa and maintenance of diversity. In recent years, a contribution of geographic distance and dispersal barriers to distribution patterns of protists and bacteria has been demonstrated ...
