Let It Snow!

My new paper is out!

Craig R. McClain, James C. Stegen, and Allen H. Hurlbert Dispersal, environmental niches and oceanic-scale turnover in deep-sea bivalveProceedings of the Royal Society B: Biological Sciences published online before print December 21, 2011, doi:10.1098/rspb.2011.2166

I discuss it over at my other website, Deep-Sea News.

In the food poor, homogenous mud flats of the deep sea, how can so many species coexist? The answer is snow…The deep-sea floor is essentially a patchwork quilt of different small habitats. I began this yearby publishing a study addressing how heterogeneity in marine snow of distances of just a few yards can lead to completely different communities of organisms. At the end of this year, just today in fact, I with coauthors show this same pattern over several thousands of kilometers.

This paper also got coverage at io9, Wired, and Discovery.
