In reading the manuscript I was surprised to see the result that abundance had declined by 21% and species richness had remained reasonably constant. This seems at odds with the observation than in both plots we see an increase in the maximum abundance and richness...

"Significance" (normally at p<0.05) is entirely an arbitrary term. However, it is used as if it is some great gold standard we must all strive for. If editors were only to allow its use when formal power calculations have been done at a specific alpha (aka significance)...

The authors did an excellent job talking about the fallacies of p-values. In addition, other summary statistics such as the mean, median, interquartile range, and r-square can skew interpretation of the results as Anscombe...

In a paper about correlations we show that many trained scientist failed to see problems in scatter plots but argue that what really matters is to establish the strength of a correlation (e...

I absolutely agree there are biases. There are further tools for correcting model biases, but they've yet to establish Bayesian methods in QUORUM statements. FYInterest: http://www.bias-project.org.uk/

This study involves healthy volunteers and not a rare patient population. A sample size of 13, which drops to 12 for skin conductance, seems odd. The experiment presumably lacks statistical power and the paper doesn’t justify or discuss this glaring limitation. Why...

I'd like to know how can I implement the permutation procedure suggested to control for spatial autocorrelation in climatic variables (used as predictor variables in fourth-corner).

Nice paper, and thanks for submitting a preprint. I have a suggestion about the use of bar plots, that hide information about the data distribution. Below some suggestions (with code) on valid alternatives. This representation hides data and confounds the...

I told my colleagues that PeerJ is a journal where they need to publish if they want their paper to be published quickly and with the strict peer review expected from a good journal.
