Plots showing millipede taxonomic effort over time in terms of species descriptions.

<p>Plot A shows the data as used to calculate global species diversity following the methods of Bebber <i>et al. </i><a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0037240#pone.0037240-Bebber1" target="_blank">[39]</a>. The y-axis corresponds to the number of species descriptions in a given year (t) while the x-axis shows the number of species accumulated at time “t-1”. A local regression line is shown fitted to the data. Plot B shows a species accumulation curve fitted with a local regression line with no trend toward asymptote. Plot C shows the taxonomic productivity over time in terms of species descriptions published yearly and is fitted with a local regression line.
