Trophic consequences of introduced species: Comparative impacts of increased interspecific versus intraspecific competitive interactions.

ABSTRACT: Invasive species can cause substantial ecological impacts on native biodiversity. While ecological theory attempts to explain the processes involved in the trophic integration of invaders into native food webs and their competitive impacts on resident species, results are equivocal. In addition, quantifying the relative strength of impacts from non-native species (interspecific competition) versus the release of native conspecifics (intraspecific competition) is important but rarely completed.Two model non-native fishes, the globally invasive Cyprinus carpio and Carassius auratus, and the model native fish Tinca tinca, were used in a pond experiment to test how increased intra- and interspecific competition influenced trophic niches and somatic growth rates. This was c
