The influence of Bromus tectorum invasion on nitrogen dynamics in an arid grassland

Citation

L J Sperry, and R David Evans, The influence of Bromus tectorum invasion on nitrogen dynamics in an arid grassland: .

Summary

Destruction of habitats by invasion of non-native organisms may alter ecosystem processes. Biotic and abiotic shifts in the soil will influence available nitrogen pools, and plant species better adapted to the altered nitrogen regimes will be more competitive. We are interested in how a recent Bromus tectorum invasion will affect the nitrogen dynamics, and if the changes associated with invasion alter the competitive status of the native plants. B. tectorum, an annual grass, germinates in the fall, while most native grass species germinate and begin root activity in the spring. B. tectorum's extensive root system monopolizes the soil profile accessing available moisture and nitrogen throughout the winter. Plots were established along [...]
