Borealis
Blanchard, Alice; Beisner, Beatrix E.; Philippe Juneau — 2022-12-20 All data relate to three plankton species: Microcystis aeruginosa, Dolichospermum flos-aquae and Chlamydomonas globosa. The factors measured for the first objective (impact of temperature variation) in lab experiments: - population growth rate - Operational and maximum photochemical yield - Relative energy dissipation by fluorescence - Relative dissipation of photochemical energy - Relative dissipation of non-photochemical energy All data relate to three species: Microcystis aeruginosa, Dolichospermum flos-aquae and Chlamydomonas globosa. The factors measured for the second objective (impact of the combination of a variation in temperature and contamination with atrazine) in lab experiments: - population growth rate - Operational and maximum photochemical yield - Relative energy dissipation by fluorescence - Relative dissipation of photochemical energy - Relative dissipation of non-photochemical energy - Photosynthetic pigment concentration

Environmental variables measured in 624 lakes across Canada [2017-2019]
Borealis
Paquette, Cindy; Huot, Yannick; Gregory-Eaves, Irene; Beisner, Beatrix E. — 2022-02-23 The file “LakePluse_env_624lakes.csv” contains environmental variables from 624 sampled as part of the NSERC Canadian Lake Pulse Network project over three summers (2017-2018-2019). Lake morphometry variables were either measured on site (lake depth), or obtained from HydroLAKES v. 1.0 (Messager et al. 2016). Water quality variables (water physical and chemical properties) were collected or measured at the deepest point of each lake, following the protocols from the NSERC Canadian Lake Pulse Network (2021). Watershed land use fractions were characterized for each lake, as described by Huot et al. (2019). Variables sampling depth and units are described in “metadata_variables.xlsx”. The file “fishTL_314lakes.csv" contains fish data in a subset of 314 lakes. Fish presence-data was collected as part of the FishHab project (fishab.weebly.com). Species trophic position were obtained using FishBase (https://www.fishbase.se/), and the highest trophic level was recorded for each lake (maxTL). Fish species were assigned a trophic position of piscivore (trophic level or TL > 3.5) or planktivore (TL ≤ 3.5) based on FishBase classification of known planktivore and piscivore species (adult stages). The total number of piscivore and planktivore taxa were then recorded for each lake.

Sub-fossil crustacean zooplankton relative abundances from 101 lakes across Canada
Borealis
Paquette, Cindy; Griffiths, Katherine; Gregory-Eaves, Irene; Beisner, Beatrix E. — 2022-02-23 This data set contains cladoceran sub-fossil relative abundances for 101 lakes across Canada sampled as part of the NSERC Canadian Lake Pulse Network project. Lakes were sampled once, over three summers (2017-2018-2019). Cores were collected using a gravity corer in the deepest point of each lake and were sectioned on site with a vertical extruder. Each lake was sampled for a “top” sediment sample, represented by the first centimeter of the surface of the sediment core, and a “bottom” sediment sample, corresponding to the 1 cm of sediment located between 3 and 4 cm from the base of the core. Cladoceran extraction and preparation followed the protocol from Korhola and Rautio (2001). Cladocerans were identified using DM 2500 Leica compound inverted microscope under 200X-400X magnification with a minimal count size of 100 individuals. Identification at the species, genus, or species complex level followed Szeroczynska and Sarmaja-Korjonen (2007) and Korosi and Smol (2012a; b). Sites are identified with Lake ID number, followed by “T” for top samples and “B” for bottom samples. Lakes IDs with respective locations (longitude and latitude coordinates) and Continental Basin allocations can be found here: https://doi.org/10.5281/zenodo.4701262 References Korhola, A., and M.

Zooplankton functional trait database for Canadian lakes
Borealis
Beisner, Beatrix E.; Paquette, Cindy; Barnett, Kerri; Finlay, Kerri; Hébert, Marie-Pier — 2022-04-22 This dataset contains functional traits of 102 crustacean zooplankton taxa sampled in 624 Canadian lakes (Pelagic sample), as well as 58 sub-fossil cladoceran taxa (Sediments sample) sampled in 101 lakes. Lakes were sampled across Canada as part of the NSERC Canadian LakePulse Network. The traits used are: feeding type (B(Bosmina)-filtration, C(Chydorus)-filtration, D(Daphia)-filtration, S(Sidae)-filtration, stationary suspension or raptorial), habitat (littoral, pelagic or intermediate) and trophic group (carnivore, herbivore, omnivore, or a combination of these). Pelagic species length of up to 10 individuals per taxon per lake were measured by BSA Environmental Services (Ohio, U.S.A.), and averaged for each taxon. Sediments sample lengths were either obtained from the literature (Demott & Kerfoot, 1982; Barnett et al., 2007; Griffiths et al., 2019), or from the Pelagic sample length data. Feeding type, habitat and trophic group functional traits were obtained from literature (Demott & Kerfoot, 1982; Barnett et al., 2007; Hébert et al., 2016; Griffiths et al., 2019).

Metadata for: Ecosystem and mixoplankton responses to pulsed allochthonous inputs to lake mesocosms
Borealis
Hughes, Riley; Sarran, Charlie; Harvey, Eric; Beisner, Beatrix E. — 2024-09-03 The research objective was to understand ecosystemic responses to different types and schedules of allochthonous inputs, with a focus on the autotrophic and mixotrophic (bacterivory) responses of nanophytoplankton to such events. We conducted a mesocosm experiment in the summer of 2022 in which we added organic matter as pulses, either through insect larvae, tree leaves or a combination of both to in-lake mesocosms (Lac Triton, Station de biologie des Laurentides). A range of response variables was sampled to capture ecosystem metabolism, community composition, and the relative contributions of autotrophic, heterotrophic and mixotrophic activities.

Observational fish data for ten important fisheries species across the province of Québec
Borealis
Beisner, Beatrix E.; Rodriguez, Marco; Lemaire, Marine; Fugère, Vincent; Barrette, Marie-France; Gagné, Stéphanie; Leclerc, Véronique; Morissette, Olivier; Pouliot, Rémy; St-Pierre, Annick; Turgeon, Katrine; Velghe, Katherine; Guay, Jean-Christophe — 2024-09-03 The data covers sampling sites over all of the province of Québec, with more data in the southern regions of the province. Data are from Hydro-Québec and the Québec Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (MELCCFP). These datasets include a heterogeneous mix of standardized and non-standardized fish surveys by government biologists and by environmental consulting firms sub-contracted by Hydro-Québec, collected between 1973 and 2021. Overall, 6498 unique sites (3087 sites in lakes, 3412 sites in rivers; reservoirs excluded), were included in the database. For each site, the data consisted of species counts (adult and juvenile life stages), location (latitude and longitude), sampling date, habitat type (lake or river) and fishing gear (three categories: electrofishing, gillnet, or seine). Climate data (means over 1970 to 2000) and elevation were extracted for each site according to the site’s location from the WorldClim website (https://www.worldclim.org/) in 2023; a site which provides global weather and climate data at high spatial resolution. All 19 ‘bioclimatic variables’ provided by WorldClim were obtained from WorldClim raster files (10-min. resolution) using the function extract from the package raster (Hijmans and van Etten 2012). Five weakly-correlated bioclimatic variables were retained: annual means for temperature and precipitation, mean diurnal temperature range, annual temperature range, and precipitation seasonality (coefficient of variation of monthly total precipitation).
