Benthic Diatom Communities in Urban Streams and the Role of Riparian Buffers
Mutinova, Petra Thea; Kahlert, Maria; Kupilas, Benjamin; McKie, Brendan G.; Friberg, Nikolai; Burdon, Francis J. (Peer reviewed; Journal article, 2020)Urbanization impacts stream ecosystems globally through degraded water quality, altered hydrology, and landscape disturbances at the catchment and riparian scales, causing biodiversity losses and altered system functioning. ... -
Biodiversity patterns of Arctic diatom assemblages in lakes and streams: Current reference conditions and historical context for biomonitoring
Kahlert, Maria; Ruhland, Kathleen M; Lavoie, Isabelle; Keck, Francois; Saulnier-Talbot, Emilie; Bogan, Daniel; Brua, Robert B; Campeau, Stephane; Christoffersen, Kirsten Seestern; Culp, Joseph M; Karjalainen, Satu Maaria; Lento, Jennifer; Schneider, Susanne Claudia; Shaftel, Rebecca; Smol, John P. (Peer reviewed; Journal article, 2020)1.Comprehensive assessments of contemporary diatom distributions across the Arctic remain scarce. Furthermore, studies tracking species compositional differences across space and time, as well as diatom responses to climate ... -
Co-occurrence, ecological profiles and geographical distribution based on unique molecular identifiers of the common freshwater diatoms Fragilaria and Ulnaria
Kahlert, Maria; Maaria Karjalainen, Satu; Keck, Francois; Kelly, Martyn; Ramon, Mathieu; Rimet, Frederic; Schneider, Susanne Claudia; Tapolczai, Kálmán; Zimmermann, Jonas (Peer reviewed; Journal article, 2022)Diatom taxonomy has evolved in recent years, with many new species described and new approaches such as molecular genetics showing the existence of cryptic diversity within currently accepted species. This cryptic diversity ... -
Gaps in current Baltic Sea environmental monitoring – Science versus management perspectives
Kahlert, Maria; Eilola, Kari; Mack, Leoni; Meissner, Kristian; Sandin, Leonard; Strömberg, Helena; Uusitalo, Laura; Viktorsson, Lena; Liess, Antonia (Peer reviewed; Journal article, 2020)Legislations and commitments regulate Baltic Sea status assessments and monitoring. These assessments suffer from monitoring gaps that need prioritization. We used three sources of information; scientific articles, project ... -
Interactions between pH and nutrients on benthic algae in streams and consequences for ecological status assessment and species richness patterns
Schneider, Susanne Claudia; Kahlert, Maria; Kelly, Martyn G. (Journal article; Peer reviewed, 2013)Eutrophication and acidification are among the major stressors on freshwater ecosystems in northern Europe and North America, but possible consequences of interactions between pH and nutrients on ecological status assessment ... -
Multitrophic biodiversity patterns and environmental descriptors of sub-Arctic lakes in northern Europe
Lau, Danny C.P.; Christoffersen, Kirsten S.; Erkinaro, Jaakko; Hayden, Brian; Heino, Jani; Hellsten, Seppo; Holmgren, Kerstin; Kahilainen, Kimmo Kalevi; Kahlert, Maria; Karjalainen, Satu Maaria; Karlsson, Jan; Forsström, Laura; Lento, Jennifer; Mjelde, Marit; Ruuhijärvi, Jukka; Sandøy, Steinar; Schartau, Ann Kristin; Svenning, Martin; Vrede, Tobias; Goedkoop, Willem (Peer reviewed; Journal article, 2020)1. Arctic and sub-Arctic lakes in northern Europe are increasingly threatened by climate change, which can affect their biodiversity directly by shifting thermal and hydrological regimes, and indirectly by altering landscape ... -
Revisiting global diversity and biogeography of freshwater diatoms: New insights from molecular data
Chonova, Teofana; Rimet, Frédéric; Bouchez, Agnès; Kahlert, Maria; Schneider, Susanne Claudia; Bailet, Bonnie; Eulin-Garrigue, Anne; Gassiole, Gilles; Monnier, Olivier; Ouattara, Allassane; Rey, Stéphanie; Rhoné, Mathieu; Keck, François (Peer reviewed; Journal article, 2023)The distribution of microorganisms has long been assumed to be cosmopolitan and primarily controlled by the environment, but recent studies suggest that microbes may also exhibit strong biogeographical patterns driven by ... -
Same same, but different: The response of diatoms to environmental gradients in Fennoscandian streams and lakes – barcodes, traits and microscope data compared
Kahlert, Maria; Bailet, Bonnie; Chonova, Teofana; Karjalainen, Satu Maaria; Schneider, Susanne C.; Tapolczai, Kálmán (Peer reviewed; Journal article, 2021)We developed and compared the performance of freshwater benthic diatom indices calculated from (i) traditional morphological species identification, (ii) Amplicon Sequence Variants (ASVs) obtained via DNA metabarcoding, ...
