title: Seedlings response to simulated browsing and water stress: insights for assisted migration plantations

description: Data collected during a greenhouse experiment simulating large mammal winter browsing and water stress on five species of North American seedlings. Data include the monitoring of soil water content during the experiment (SoilWaterContent.txt), mortality of the seedlings (Mortality.txt) and values of growth, biomass and chemical compounds for each seedling included in the experiment (ExpResults.txt). Details on the experimental methods are available in Turgeon et al (in prep.) and the metadata is available below.<b>Metadata common to all files</b>Species: Seedling species; CHR = Quercus rubra; THO = Thuja occidentalis; PIB = Pinus strobus; CET = Prunus serotina; ERS = Acer saccharum.Analogue: Seedling climate analogue (see Turgeon et al.), either 2018 (analogue to current climate at plantation site), 2050 (analogue to climate predicted for 2050 at plantation site), 2080 (analogue to climate predicted for 2080 at plantation site).ID: sequential number identifying seedlings from same species-analogue combination.<b>Metadata SoilWaterContent.txt</b>date: Date of collection of the soil sample (Format: YYYY-MM-DD)soilwater: soil water content (%), evaluated using the wet and dry mass of the sample ((wet mass – dry mass)/wet mass x 100).<b>Metadata Mortality.txt</b>This file only list seedlings that died either before the onset of the water stress treatment or during the water stress treatment.browsing: browsing treatment, either browsed (‘Brout’) or unbrowsed (‘NoBrout’).waterstress: water stress treatment level, either no-stress (watering at 80% of pot capacity, 1L; ‘NoStress’), moderate stress (50% of pot capacity, 0.5 L; ‘stress1’) or high stress (25% of pot capacity, 0.3 L; ‘stress2’. Seedlings that died before the onset of the treatment are identified by ‘before’.bloc: experimental block in which is located the seedling. NA values are for seedlings that died before the onset of the treatment<b>Metadata ExpResults.txt</b>browsing: browsing treatment, either browsed (‘Brout’) or unbrowsed (‘NoBrout’).waterstress: water stress treatment level, either no-stress (watering at 80% of pot capacity, 1L; ‘NoStress’), moderate stress (50% of pot capacity, 0.5 L; ‘stress1’) or high stress (25% of pot capacity, 0.3 L; ‘stress2’.hauteurini: seedling height before the experimental treatments.hauteur: seedling height at the end of the experiment.diam: diameter at the base at the beginning of the experiment.ram: number of shoots &gt;5 cm (evaluated according to Potvin 1995) at the end of the experiment.maerien: aboveground mass (g) of seedlings at the end of the experiment.mracine: belowground mass (g) of seedlings at the end of the experiment.mtot: total mass (g) of seedlings at the end of the experimentratio: aboveground mass/belowground massmret: nitrogen: nitrogen content of foliage (broadleaf species) or shoots (wood + needles, coniferous species); g/kg.phen: total phenolic content of foliage (broadleaf species) or shoots (wood + needles, coniferous species); mg/g.flav: flavonoid content of foliage (broadleaf species) or shoots (wood + needles, coniferous species); mg/g.<b>Reference</b>Potvin, F. 1995.
