In addition, check out these drawings that the Sydney did to illustrate some of the wing morphological measurements. It's rare to find a biologist who can both crush it with statistical analysis AND be artistically inclined at the same time. Nice work Sydney!

A plot showing prestige (impact factor) on vertical axis and fees charged by journals on horizontal axis.

Journal fees for open access are becoming obscene. But what are we, scientists, paying for? I made a simple plot with journals in my research area(s). Clearly, we are paying for prestige: a shockingly clean correlation between the impact factor and journal fees
