MARC recordEffects of nitrogen fertilization on plant communities of nonsorted circles in moist nonacidic tundra, northern Alaska / Alexia M. Kelley, Howard E. Epstein.
| Title: | Effects of nitrogen fertilization on plant communities of nonsorted circles in moist nonacidic tundra, northern Alaska / Alexia M. Kelley, Howard E. Epstein. |
| Author(s): | Kelley, Alexia M. Epstein, Howard E. |
| Date: | 2009. |
| In: | Arctic, Antarctic, and Alpine Research. (2009.), Vol. 41(1) (2009) |
| Abstract: | Reports results of experiment in which nonsorted circles and surrounding more stable vegetation are fertilized, to determine if nitrogen availability limits plant communities on disturbance dominated features. Fertilized stable vegetation shows increase in graminoid biomass and decrease in moss biomass but no total biomass response. Plant communities on nonsorted circles are less responsive to addition of nitrogen. Difference in fertilizer response indicates that presence of these features creates spatial heterogeneity in tundra plant community dynamics that should be taken into account when studying tundra responses to environmental change. |
