I am happy to announce that one of the papers resulting from my dissertation research, on head-butting in goats, is now freely available for download. You can get the paper in HTML or PDF form. For a previous blog post on the topic, check here. Journal of Experimental Biology is one of the progressive mainstream journals that opens up their archives after six months. . .it is a high-profile publication (impact factor in 2007, for what it's worth, of 2.972), and there are a lot of really cool papers in there (beyond mine, of course). Go check it out!
