Abstract/Summary

The spatial relationship between the concentration and deposition of the major ions in precipitation and stemflow and their influence on the tissue nitrogen concentration of 3 epiphytic bryophytes on Quercus petraea and Q. robur was investigated at 7 UK Atlantic oak woodland sites with a range of total N deposition of 55-250 mmole m-2. The main driver of change in tissue N concentrations of 3 epiphytic bryophytes (Isothecium myosuroides Brid. (Eurhynchium myosuroides (Brid.) Schp.), Dicranum scoparium (Hedw.) and Thuidium tamariscinum (Hedw.) was total N deposition in stemflow, dominated by ammonium deposition. The 3 epiphytic species also showed strong relationships between tissue N concentration and total N deposition in rainfall but a poor correlation with total N ion concentration in rainfall. This study shows that epiphytic bryophytes utilise stemflow N and thus increase their risk from inputs of total N deposition compared to terricolous species at the same site.
