Day1, Xiaobo Wang1, Ekaterina Voronina1 1Division of Biological Sciences, University of Montana This protocol demonstrates use of the proximity ligation assay to probe for protein-protein interactions in situ in the C. elegans germline. Environment Quantifying Corticolous Arthropods Using Sticky Traps Michael W. Eichholz*1, Elise C. Zarri*2, Kevin P. Sierzega*1 1Cooperative Wildlife Research Laboratory, Center for Ecology, Department of Zoology, Southern Illinois University, 2Montana Cooperative Research Unit, University of Montana We describe a semi-quantitative approach of measuring characteristics of corticolous (bark-dwelling) arthropod communities. We placed commercially manufactured sticky traps on tree boles to estimate abundance, total length (a surrogate to biomass), richness, and Shannon diversity for comparison among tree species.
