Canonical correspondence analysis (CCA) was utilized to model variation in community composition and structure relative to environmental gradients including: elevation, slope, soil texture, soil pH, available nitrogen, available phosphorus, and available potassium. Data were collected in Nevada's Toiyabe Range, a southwest-northeast trending fault-block range in the central Great Basin. A survey of 43, 400m<super>2</super> macroplots and 86, 1m<super>2 </super> nested microplots was conducted on the west slope of the Toiyabe Range during the months of June, July, and August 1999, and August 2000.

520 $a Canonical correspondence analysis (CCA) was utilized to model variation in community composition and structure relative to environmental gradients including: elevation, slope, soil texture, soil pH, available nitrogen, available phosphorus, and available potassium. Data were collected in Nevada's Toiyabe Range, a southwest-northeast trending fault-block range in the central Great Basin. A survey of 43, 400m<super>2</super> macroplots and 86, 1m<super>2 </super> nested microplots was conducted on the west slope of the Toiyabe Range during the months of June, July, and August 1999, and August 2000.
520 $a Within the ordination model, seven non-discrete woodland and shrubland assemblages were characterized in relation to interspecific and species-environment interactions. Gradients contributing significantly (p ≤ 0.05) to the ordination include: elevation, slope, percentage of sand in the mineral substrate, and soil pH. The CCA model illuminates numerous associative and mutually-exclusive interactions among montane taxa in relation to dominant environmental gradients, and provides an informational basis for future investigations.
