This is Dan Simberloff with his mandolin. Dan was my Ph.D. advisor and co-author of several papers (see Vázquez and Simberloff 2002, Am. Nat.; 2003, Ecol. Lett.; 2004, Ecol. Monogr.).
Why interactio? No, we didn't misspell it. It means interaction in latin. Why latin? For no particular reason, we just liked it. Also, our logo represents an ecological network in which species or individuals (colored circles) are connected by interactions (grey lines); it was designed by Virginia Chirilá.
