Biological intercalibration: Invertebrates 2022
(NIVA-rapport;7840-2023, Research report, 2023)The ICP Waters biological intercalibration of invertebrates was executed to harmonise taxonomic work across countries and is of high value in programmes where the focus is on community analyses, e.g., for the classification ... -
Effects of nitrogen on nutrient-limitation in oligotrophic northern surface waters
(NIVA-rapport;7680, Research report, 2021)Nitrogen deposition has a potentially eutrophying impact on oligotrophic freshwaters. Here we present a data analysis and a literature review with a joint focus on nitrogen (N) limitation in oligotrophic lakes and rivers. ... -
