Heavy Metal Music and Adolescent Suicidal Risk [2001, Canada]
— 1997 [EN] This study probes the differentiating characteristics (family relationships, social– psychological attitudes, drug use, and suicidal risk) of youth who prefer heavy metal (HM) music, worship music, and use music for vicarious release. Data analysis was based on a sample of 275 secondary school students between the ages of 14 and 18. Logistic regressions revealed that HM music preference and worshipping is not significantly related to suicidal risk when controlling for other risk factors. These findings were found for both boys and girls. Surprisingly, the use of music for vicarious release was inversely related to suicidal risk for girls. These findings are discussed within the framework of Arnett’s alienation theory (Arnett, J. (1991). J. Youth Adolesc. 20(6): 573–592) and Roe’s uses-gratification theory (Roe, K. (1995). J. Youth Adolesc. 24(5): 617–631) regarding adolescent socialization and media purposes. [FR] Cette étude vise à explorer la théorie d'Arnett (1996) et de Roe (1995) qui implique le lien entre l'aliénation et la préférence musicale pour le « heavy metal ». Cet article tente de vérifier l'hypothèse stipulant une influence de la préférence pour la musique heavy metal sur le risque suicidaire indépendamment des caractéristiques sous-jacentes à cette sous-culture. Cet article vise également à explorer les facteurs de risques des comportements suicidaires liés à la vénération et à l'écoute cathartique de la musique. Comme le suggèrent Arnett (1991, 1996) et Martin et coll. (1993) les analyses statistiques seront réalisées en considérant séparément les garçons et les filles.

Willow aboveground and belowground traits can predict phytoremediation services
— 2019-09-13 We explored traits-services correlations with plantations of short-rotation coppiced willows (Salix spp.). We conducted a four-year field trial (2016-2019) on a brownfield contaminated by trace elements (As, Ba, Cd, Cu, Mn, Pb, Se, and Zn), using split-plots nested into four blocks. We sampled 16 willow plantations (4.5m X 2.5m) of one or four cultivars from which half was coppiced after three years. For each plot, we measured ten functional traits from aboveground and belowground tissues (LA, SLA, LDMC, RDMC, LNC, RNC, LCC, RCC, SSD, and leaf pH) and six phytoremediation services (Phytoextraction, phytostabilisation, translocation factors, soil decontamination, and bioconcentration factors of total and belowground tissues). To do so, we measured trace elements in plant tissues and soil. We tested the impacts of treatments (willow diversity and coppicing) on the services and traits through linear mixed models and controlled for spatial heterogeneity with soil covariates (OM, texture and initial contamination). We explored the traits-services correlations through a redundancy analysis (RDA).

Zooplankton functional trait database for Canadian lakes
— 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).

Québec Lake Sampling Data 2019, LimnoScenES project
— 2022-03-04 Data were collected in summer 2019, through 3 regions on Southern Québec (Estrie, Laurentides, Outaouais), Canada. For each sampled lake, data were collected for bacterioplankton, phytoplankton, zooplankton and environmental parameters. Data for lake name, region, date, latitude (°), longitude (°), maximum depth (m), average depth (m), area (km²), water residence time (year-1), fetch (m); Lakes were sampled at the deepest point. Data collected for Secchi depth (m) and profiles of: dissolved oxygen (mg/L), temperature (°C), pH, BBE Phycoprobe (µg/L); Vertical net hauls across water column for crustacean zooplankton: species, size (mm), biomass (µg/L). Vertical tube samples for phytoplankton taxa, size (µm), biovolume (µL/L); Bottle samples (0.5m depth) were taken from each lake’s deep point for chlorophyll a (µg/L), total nitrogen (mg/L), total phosphorus (µg/L), dissolved organic carbon (mg/L), water color (A440) (m-1) and bacterial 16S metagenomics.

Environmental variables measured in 624 lakes across Canada
— 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.

Zooplankton biomasses from 624 lakes across Canada from 2017 to 2019
— 2022-02-23 We examined crustacean zooplankton biomass in 624 freshwater lakes spanning 12 ecozones within 6 continental drainage basins as part of the NSERC Canadian Lake Pulse Network project. Lakes were sampled once, over three summers (2017-2018-2019). Zooplankton were collected at the deepest point of each lake using a 100μm mesh Wisconsin net. Zooplankton were anesthetized with CO2 (Alka-Seltzer) and samples were preserved at room temperature in 70% ethanol. Samples were identified to the species level by BSA Environmental Services (Ohio, U.S.A.) using a dissecting microscope (100x to 400x magnification). Species biomasses were calculated by BSA using the mean length of up to 10 measured individuals per taxon per lake (Beisner et al., 2021), and known size/weight relationships for each species (Dumont et al., 1975; McCauley, 1984; Lawrence et al., 1987). The file “zooplankton biomass” contains the biomasses (µg d.w./L) of 102 crustacean zooplankton taxa from 624 lakes across Canada. The file “lake location” contains the location (longitude and latitude coordinates) and respective Ecozone and Continental Basin allocations of the 624 lakes. pelagic crustacean zooplankton biomass (µg d.w./L)

Replication Data for: The translation of ‘transparency’ in the Canadian press: An inquiry into symbolic power
— 2018-09-26 This corpus investigate the business sections of seven Canadian newspapers over a period spanning from 2001 to 2008 in English and in French. The newspapers are: The National Post, The Globe and Mail, The Toronto Star, The Gazette, La Presse, Le Devoir and Le Droit. For comparison purposes, a corpus made of Canadian bank's annual reports was also used. With the use of the monolingual concordancer WordSmith 6.0, we looked at the following keywords: transparency, opaque and their French equivalents. The results were treated in several Excel files.
