Baud, Alexandre;Aulard, Candice;Gregory-Eaves, Irene;Francus, Pierre;Huot, Yannick;del Giorgio, Paul;Antoniades, Dermot;Fradette, Maxime;Ghanbari, Hamid;Smol, John — 2022-12-13Radioisotopic and ancillary data (i.e., estimated temperature, precipitation and population in lake watersheds) for 37 lakes across Eastern Canada collected by the LakePulse Program in 2017
Tapics, Tara;Huot, Yannick;Walsh, David — 2023-12-08
Data were collected every two weeks in summer and every four weeks in winter beginning fall 2012 and ending fall 2015 in the Quebec (Canada) lakes Lac Croche, Lac Montjoie, and Lac SImoncouche. On each sampled date, a temperature profile was taken and analysed to determine if the lake was stratified or not. When stratified, discrete samples were taken for chemical and biological analyses in both the epilimnion and the metalimnion. When mixed, discrete samples for chemical biological samples were taken from one depth within the mixed layer. Profiles of lake oxygen, temperature, conductivity, and pH were taken, as were profiles of phytosynthetically active irradiance (PAR).
Paquette, Cindy;Fradette, Maxime;Huot, Yannick;Gregory-Eaves, Irene;Beisner, Beatrix E. — 2022-02-23Land use fractions (urban, mines, agriculture, pasture, forestry, managed grassland, water and natural landscape) and associated human impact index in 101 lake watersheds sampled as part the NSERC Canadian Lake Pulse Network project. Land use and human impact index were calculated as described in Huot et al. (2019).

Paquette, Cindy;Huot, Yannick;Gregory-Eaves, Irene;Beisner, Beatrix E. — 2022-02-23The 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.
