Ecological relevance of non-perennial rivers for the conservation of terrestrial and aquatic communities. [PDF]
Conserv Biol, 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

Microbially influenced corrosion and rust tubercle formation on sheet piles in freshwater systems
Environmental Microbiology, Volume 25, Issue 10, Page 1796-1815, October 2023., 2023 Abstract The extent of how complex natural microbial communities contribute to metal corrosion is still not fully resolved, especially not for freshwater environments. In order to elucidate the key processes, we investigated rust tubercles forming massively on sheet piles along the river Havel (Germany) applying a complementary set of techniques.

Journal of Phycology, Volume 59, Issue 3, Page 590-602, June 2023., 2023 Abstract Microphytobenthos (MPB), typically comprised mainly of diatoms, is a key contributor to nearshore energy flow and nutrient cycles. Deposit‐feeding invertebrates are known to alter the structure and activity of MPB. The eastern mud snail Ilyanassa obsoleta can reach extremely high densities in estuaries of the northwestern Atlantic, and their ...

Diversity and distribution of lacustrine diatoms along the Trans‐Mexican Volcanic Belt
Freshwater Biology, Volume 68, Issue 3, Page 391-405, March 2023., 2023 Abstract The Trans‐Mexican Volcanic Belt is recognised as a highly biodiverse zone and we present a study of diatom diversity and species distributions in its lakes. We aimed to identify diatom taxa with the highest regional occupancy, explore diversity at a regional level, identify the main variables associated with species distributions, and present ...

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.

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

Primer registro de Thalassiosira catharinensis (Bacillariophyta) en aguas costeras marinas argentinas [PDF]
, 2018 Several ultrastructural analyses of taxa belonging to the genus Thalassiosira from Argentinean coastal waters were carried out, nevertheless, the smaller fraction of the nanoplanktonic Thalassiosira was frequently overlooked.

Flora algal de la cuenca del río Guadalquivir: Su valor en la determinación de la ecorregionalización de la cuenca [PDF]
, 2018 In compliance with the Water Framework Directive of the European Union, we needed to diagnose the ecologic quality of the different sections of the rivers of the Guadalquivir basin. In order to establish a regional classification of the water bodies by a
