Revealing biases in insect observations: A comparative analysis between academic and citizen science data.

In fact, a highly significant relationship was found between the (log-transformed) number of users uploading observations in each insect order and the (log-transformed) number of observations in each order (Pearson’s correlation test, r = 0.97, t = 17.26, df = 17, p-value < 0.001), as well as between the number of users per order and the Shannon’s diversity index of each order (Pearson’s correlation test, r = 0.96, t = 10.92, df = 11, p-value < 0.001) and the Shannon’s diversity index of each order and the total number of observations per order (Pearson’s correlation test, r = 0.94, t = 8.98, df = 11, p-value < 0.001).
