A phylogenetic tree of the Phylum Nematoda based on that of Blaxter et al. [25]showing the distribution of anhydrobiotic and desiccation tolerant taxa, along with their trophic ecology, across the Phylum. (¶Erkut et al. have recently shown that C. elegans dauer larvae can survive exposure to low relative humidity following preconditioning at 98% RH for 4 days [26]).
