Belowground c allocation estimated as soil respiration minus aboveground litter inputs sarah abbott
1. Belowground C Allocation Estimated as
Soil Respiration Minus Aboveground
Litter Inputs
Sarah Abbott with Tim Fahey, Ruth Yanai,
Alex Young, and Shiyi Li
6. Calculating belowground C allocation requires
putting both of these in the same units and
estimating year-round soil respiration--stay tuned!
RESULTS
N decreases soil respiration
(and likely belowground C allocation)
P decreases leaf production
(does this relate to greater diameter growth?)
Can we conclude that P matters more aboveground
and N matters more belowground?
Editor's Notes
What goes down must come up. Litterfall must get respired, in the long run,
** No Detectable Difference
Hypothesis:
H0: μC = μN = μNP =μP
H1: at least one of means is different
F: 1.73
Fcrit: 2.81
Reject hypothesis
P value: 0.17

Here we perform Analysis of Variance (ANOVA) to test whether the means of the treatment types are equal. The one-way analysis of variance is used to determine whether there are any statistically significant differences between the means of three or more independent groups. It’s odd that the technique is called "Analysis of Variance" rather than "Analysis of Means." but appropriate because inferences about means are made by analyzing variance.
The X is the mean
Bar is median
Box is interquartile range (middle 50%)
Whiskers are extrema
ANOVA and Box whisker plots suggest that N and N+P may
