Competitiveness of the Exotic Silphium perfoliatum against the Native Urtica dioica: A Field Experiment
Silphium perfoliatum (cup plant) is native to North America and is increasingly used as a bioenergy crop in Germany. Spontaneous occurrences of this species have already been detected in several European countries. To assess the possible risk to biodiversity by spreading of S. perfoliatum, we investigated the competitiveness of this species against the native and highly competitive Urtica dioica over four years in a field experiment in Bayreuth (Germany). S. perfoliatum grew well among U. dioica, although its biomass was strongly reduced by surrounding U. dioica. Projection area, plant height, and reproductive potential were less or similarly reduced by surrounding U. dioica as by the intraspecific competition. Moreover, S. perfoliatum significantly suppressed the growth of the competitive U. dioica. A settlement and establishment of S. perfoliatum in the native flora of Central Europe and a suppression of uncompetitive plant species are therefore conceivable.
期刊介绍:
The main aim of the International Journal of Ecology & Development (IJED) is to publish refereed, well-written original research articles, and studies that describe the latest research and developments in ecology and development. It also covers the many potential applications and connections to other areas of Ecological Science, economics and technology such as the use and development of mathematics/statistics in ecology or use and development of economics for ecology & development or inter-disciplinary nature of applications for Ecology & Development. International Journal of Ecology and Development is published three issues in a year in Winter, Summer and Fall.
