| Abstract | The cordgrass Spartina alterniflora has invaded mangrove-dominated habitats in China during the last few decades. However, the ecological effect of the S. alterniflora on the mangrove fish community is poorly understood. In order to assess the relative nutritional contributions of native autotrophs (benthic microalgae: BMA, particulate organic matter: POM, C3 native mangrove Aegiceras corniculatum, Avicennia marina and Kandelia obovata) and C4 exotic S. alterniflora, we examined the stable carbon and nitrogen isotope values of six common fish species (Osteomugil ophuyseni, Coilia grayii, Parachaeturichthys polynern, Sparus latus, Lateolabrax japonicas and Ophichthus apicalis) in the tidal creek of Zhangjiang Estuary. Results of the MixSIR model suggested that exotic S. alterniflora combined with BMA constituted major food sources of the fish community. S. alterniflora had a higher median contribution than all the other food sources to all fish species except for P. polynerna and S. latus, which derived their major food sources from BMA. These results indicated that the invasive cordgrass has been incorporated into the local aquatic food web through providing important nutrient source for fish species in the mangrove ecosystem of Zhangjiang Estuary. |

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.
