Tylenchida is one of the most significant groups of soil nematodes because it includes most small plant parasites (about 500-800 um long) that are agricultural pests. With respect to taxonomy most of these agricultural nematodes are well-studied, but what is less known are related species that are common in habitats relatively undisturbed by anthropogenic effects. These less studied Tylenchida are nevertheless crucial to developing a phylogenetic framework for the group, as a basis for classification of the entire group. Preliminary results, in conjunction with other projects at Deep Canyon, have demonstrated an abundance of tylenchid diversity in the region, including some species new to science. Many of these species occur in wash areas and it is likely that a majority have the capacity to undergo anhydrobiosis during periods in the desert when conditions are otherwise unfavorable for feeding and reproduction. Our goal is to sample areas already identified as promising sources of specimens. These will be collected as soil samples of about 500 cc; they can either be processed on site or at UCR by standard methods of screening and funnels. Freshly collected specimens can be returned in coolers to our UCR laboratories where they can be processed for classical microscopy and well as DNA sequening. Specimens, including types of new species, can be deposited in the UCR Nematode Collection. The project is supported in part by NSF funding to PI Baldwin. Published results will recognize the role of the UC Boyd Deep Canyon in the study.
