Description
Non-native grasses, originally introduced for pasture improvement, threaten Australia's iconic low-resource grasslands and a thorough understanding of the life-history strategies associated with these species is essential for effective management. Comparing invasive qualities across four congener pairs of native and non-native grasses, it was revealed that non-natives displayed a unique combination of morphological and physiological traits compared to natives. This study applied a novel technique of microdialysis and found that native and non-native grasses use soil nitrogen differently, likely contributing to the competitive advantage shown by non-native grasses across Australia.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
