PHACEphenology_summary_final_forSD

Mean timing of life cycle events (in DOY) for all species in all treatments in all years. Treatment designation are as follows: ct are the ambient CO2, ambient temperature treatments (i.e. control); cT are the ambient CO2, warmed treatments; Ct are the CO2 enriched, ambient temperature treatments; and CT are the CO2 enriched, warmed treatments. Marked (*) cells designate those species that initiated leaf emergence and flower production earliest, and seed maturation and senescence latest in the season within a treatment within a year. Standard errors (SE) are included in parenthesis where applicable. Where SE is blank, there was no variation in induction dates for that particular species or the sample size was not more than one individual per treatment per year. Number of plots (n) where species did occur per treatment is also included (maximum possible n is 5)

Relative abundance of nematode families in soil from stands of three tree species.

<p>Relative abundance of nematode families in order of mean abundance in stands of (A) aspen, (B) pine, and (C) spruce. Letters after each family denote feeding group: PP, plant parasite; RA, root associate, BF, bacterial feeder; FF, fungal feeder; OM, omnivore; and PR, predator. Values are means±SE.</p

Abundance of nematode feeding groups in stands of three tree species (mean±SE) and <i>F</i> and <i>P</i> values from ANOVA.

<p>Abundance of nematode feeding groups in stands of three tree species (mean±SE) and <i>F</i> and <i>P</i> values from ANOVA.</p

Microbial biomass and community composition in soil from stands of three tree species.

<p>Microbial biomass (A) C and (B) N, (C) fungal to bacterial rRNA gene ratio, and (D) fungal and (E) bacterial community composition (based on NMS ordination scores) in stands of each species. Values are means±SE and letters denote significant differences (<i>P</i> = 0.05) among tree species (upper and lower case letters refer to NMS axis 2 and 3, respectively, for bacterial community composition).</p

ANOVA output of the effect of tree species and block on soil properties and animal abundances.

*<p>Based on ordination scores for the three axes that explained the most variance in the NMS analyses.</p

Leaf litter quality and root biomass of tree species (mean±SE) and <i>F</i> and <i>P</i> values from ANOVA.

*<p>Fine roots were<1 mm diameter; coarse roots were >1 mm diameter.</p>§<p>Not applicable since there was only one litter sample per stand.</p>†<p>Different letters denote significant differences among tree species (<i>P</i> = 0.05).</p

Mesofaunal abundance in soil from stands of three tree species.

<p>Abundance of (A) collembola, and (B) mesostigmatid, (C) oribatid, and (D) prostigmatid mites in stands of aspen, pine, and spruce. Values are means±SE and letters denote significant differences among tree species (<i>P</i> = 0.05).</p

Soil physical and chemical properties and respiration rates in stands of three tree species.

<p>Soil (A) temperature, (B) moisture, (C) pH, and (D) respiration rates in stands of each species. Values are means±SE and letters denote significant differences among tree species (<i>P</i> = 0.05).</p
