Abstract
Riparian areas within a given arid region frequently contain broadly similar plant communities despite substantive geographic separation. Whether they also harbor similar communities of fungal symbionts, or feature assemblages unique to each riparian zone, is unknown. We examined fungal endophytes in foliage of woody angiosperms in six riparian areas in Arizona. Abundance and diversity differed among host species according to leaf longevity and phytochemistry, and among sites as a function of rainfall. Community composition varied among sites and host species. Comparison with regional data revealed that riparian areas harbor different subsets of the regional mycota rather than a consistent group of riparian taxa. Overall a high species- and phylogenetic richness of endophytes was recovered, especially among Mycosphaerella and affiliated anamorphs. Variation in endophyte communities across sites despite the relative consistency of plant communities underscores the importance of riparian zones both singly and in combination for harboring fungal biodiversity.
