| Abstract | Previous studies suggest that a disproportionately high number of invasive plant species are clonal, and that an increase in N availability often promotes the spread of introduced plants. We tested the hypothesis that greater ability to increase performance in response to the increase in N availability is associated with greater invasiveness in clonal plant species on a regional basis in China, where the potentials for new introductions and for N deposition are high. We compared growth, allocation of mass, morphology, and N use efficiency in six pairs of closely related, widespread species of clonal plants with and without N addition designed to simulate future N deposition of 15 g N m$^{−2}$ year$^{−1}$. Within each pair, one species was introduced and invasive in China, and the other was native or in one case introduced but not invasive. Added N increased the final dry mass of species by 10–120 % and the final number of ramets by up to 300 %. However, responses to N did not differ consistently (P > 0.05) between invasive and native or non-invasive species; increase in total mass with added N ranged from being 6 times greater in the invasive species to 3 times greater in the native species in a pair. Results suggest that increased N availability due to deposition in China will favor the spread of some but not all introduced, clonal plant species in China. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
