Host species and size affect epiphytic cryptogam communities in a mixed-evergreen forest.

Epiphytic cryptogams such as macrolichens, mosses, and leafy-liverwort share important components of the diversity, structure, and nutrient cycling of forest communities, and provide numerous ecosystem services. To establish a comprehensive, publicly available ecological data set as a foundation for forest cryptogam research, we conducted a detailed census of the spatial diversity and abundance of epiphytic macrolichen, moss, and leafy-liverwort species on the University of California Santa Cruz Forest Ecology Research Plot, a 6-ha mixed-evergreen forest research site on the UCSC Campus Natural Reserve. We recorded sixty-three cryptogam taxa from 6,967 tree trunks representing 28 woody species. Non-metric multidimensional scaling ordination indicated that that lichen, moss, and liverwort species were clustered differentially in space. Multi-response permutation procedures and non-parametric multivariate analysis of variance suggested that cryptogamic epiphyte communities differ among both host species and trunk diameters. Within host species, variation in cryptogam community composition increased with host size. The detailed spatial survey allows analysis of distribution patterns of even rare cryptogam species, as well as comparison of multivariate methods for epiphytic community analysis.
