Abstract

{A 15N-addition mesocosm experiment was used to study competition for nitrogen (N) between the aggressive cattail species Typha × glauca (T. latifolia × T. angustifolia) Godr. (hybrid cattail) and a suite of native plant species often found in marshes Typha invades. Plant uptake of 15N released from labeled Typha and native-species litter was then measured in a pot experiment with new cohorts of two native plant species (Juncus balticus Willd. and Schoenoplectus acutus Muhlenberg ex Bigelow) grown with and without Typha. In both experiments, species differed in their above- and belowground uptake of 15N, with Typha outperforming the other species (1.7–5.0-times greater mean uptake
