Metadata for “Physicochemical and biological variables measured in 110 national monitoring lakes between 1992 and 2022”. Lake monitoring data were downloaded from the data host https://miljodata.slu.se/MVM/

Sampling and analyses of all abiotic and biological variables were based on standard protocols throughout the study period. These protocols are quality controlled and certified by the Swedish Board for Accreditation and Conformity Assessment (SWEDAC; https://www.swedac.se/). All physicochemical and biological analyses were performed at the Department of Aquatic Sciences and Assessment following international (ISO) or European (EN) standards (Fölster et al., 2014). Detailed information concerning methods and quality control can be found at https://www.slu.se/en/departments/aquatic-sciences-assessment/laboratories/vattenlabb2/.

File information

Lake physicochemical variables measured in 110 lakes between 1992 and 2022. Mid-lake surface water samples (0.5 m) were taken annually during four sampling intervals (March to November, representing spring, summer, autumn and winter seasons) over a 31-year study period between 1992 and 2022 using a Plexiglas? sampler and monthly averages were calculated.

Data for monthly average daily mean air temperature and precipitation extracted from the interpolated Climate Research Unit gridded Time Series dataset (version 4.06; Harris et al., 2020; https://crudata.uea.ac.uk/cru/data/hrg/) for 0.5° latitude by 0.5° longitude grid cells corresponding to the geographic locations of the lakes were used to calculate annual mean air temperature (°C) and precipitation (mm per month for each lake in each year).

Phytoplankton was sampled quantitatively in late summer (August) with a tube sampler from the epilimnion in the open-water mid-lake area. Biovolumes (mm3/l) for individual species were calculated using geometric shapes and summed to obtain total phytoplankton biovolume (BioV). Taxon biovolumes were Hellinger transformed.

Phytoplankton data was converted to five biological metrics: number of taxa, biovolume (phytoplankton BioV), relative biovolume (%) of cyanobacteria, diversity (Hill’s N2 calculated using Canoco) and Euclidean distance (a measure of between-year variability in assemblage composition). Between-year Euclidean distance was calculated as the distance between two consecutive years of detrended correspondence axes 1-3 scores derived using Canoco software (version 5.12, ter Braak and ?milauer 2018; ?milauer and Lepes 2014) as d=√((x2 – x1)? + (y2 – y1)?) + (z2 – z1)?), where x1, y1, z1 represent DC axis scores one, two and three, respectively, at any year and  x2, y2, z2 represent DC axis scores one, two and three, respectively, for the previous year.

Benthic macroinvertebrate samples were collected in autumn (mainly October/November) from littoral habitats using standardised kick sampling with a hand net (0.5 mm mesh). Five standardised kick samples (20-s duration, 1 m long, ca 0.5–1 m depth) were taken from stony, vegetation-free sites in each lake. Taxon abundances (numbers per unit effort) were Hellinger transformed.

Benthic macroinvertebrate samples were collected in autumn (mainly October/November) from profundal habitats using an Ekman grab (247 cm2). Five samples were taken within a 150 m x 150 m quadrate situated over the deepest area of the lake. Taxon abundances (number of individuals per m2) were Hellinger transformed.
