Glad to report another paper coming out by Tiffanie Nelson in PLoS ONE. It describes a large scale comparison of gut microbes from mammals living in terrestrial and marine systems and is aptly titled

Tiffanie M Nelson, Tracey L Rogers, Mark V Brown

There are some intersting differences betweens mammals inhabiting the different biomes and Tiff speculates as the the causes. Link when it becomes available
