Velle, Gaute; Mahlum, Shad; Monteith, Don T.; de Wit, Heleen; Arle, Jens; Eriksson, Lars; Fjellheim, Arne; Frolova, Marina; Fölster, Jens; Grudule, Natalja; Halvorsen, Godtfred A.; Hildrew, Alan; Hruška, Jakub; Indriksone, Iveta; Kamasová, Lenka; Kopáček, Jiří; Krám, Pavel; Orton, Stuart; Senoo, Takaaki; Shilland, Ewan M.; Stuchlík, Evžen; Telford, Richard J.; Ungermanová, Lenka; Wiklund, Magda-Lena; Wright, Richard F. (NIVA-rapport;7077, Research report, 2016-09)This is a study of the international impact of acid emission reductions on vulnerable freshwater biodiversity of benthic macroinvertebrates. In order to properly attribute impacts it is necessary to also incorporate the ... -

Time series were ... -
Trends and patterns in surface water chemistry in Europe and North America between 1990 and 2020, with a focus on calcium
Vogt, Rolf David; Agnieszka, Kolada; Arle, Jens; Austnes, Kari; Van Dam, Herman; Futter, Martyn; Fölster, Jens; Gundersen, Cathrine Brecke; Higgins, Scott N.; Houle, Daniel; Hruska, Jakub; Monteith, Don; Paterson, Andrew; Rogora, Michela; Sample, James Edward; Stoddard, John; Steingruber, Sandra; Ulanczyk, Rafak; Vuorenmaa, Jussi; de Wit, Heleen (NIVA-rapport;7931-2024, Research report, 2024)The report presents trends in major anions and cations, pH, TOC and bicarbonate in surface waters in Europe and North America from 1990 to 2020. Special attention is given to trends in calcium, which showed some unexpected ...
