Table 2. Results from SIMPER analyses, listing the six most important species according to its contribution to the dissimilarity between arthropod assemblages in adjacent biomes: DS = Desertscrub, GL = Grassland, CH = Chaparral, and PO = Pine Oak, P = Pine, MC = Mixed Conifer.
Capital letters preceding species names indicate to which major arthropod group the species belongs (C-Coleoptera, A- Araneae, O-Orthoptera, M-Myriapoda).
