I love this ... "Dr. Eleanor's Book of Common Ants" based in part on citizen science data
This is really cool: Dr. Eleanor's Book of Common Ants. Free to download. With incredible pics from Alex Wild. And based in part on data from the School of Ants citizen science project. You can download the PDF or the iBook from iTunes. From the folks at "Your Wild Life" including Holly Menninger and Rob Dunn and others. Definitely worth checking out.
