Abstract

Microhabitat preferences and species-environment patterns were quantified for bryophytes in blue oak woodlands and forests of central coastal California. Presence data for mosses collected from 149 400 m2 plots were analyzed using canonical correspondence analysis (CCA), a multivariate direct gradient analysis technique. Separate ordinations were performed for terricolous, saxicolous and epixylic mosses using 14 environmental variables. Fifty-six species of bryophytes were collected from the study area. Only the terricolous moss CCA was shown to be significantly related to environmental variables. Thirty-nine soil bryophyte species were arranged along 4 environmental gradients: potential annual solar insolation, moderate soil trampling, tree density and overstory crown cover. The significance of each environmental factor is discussed in relationship to the ecology of the species.
