| Abstract | Exposure of plants to vehicle exhaust emissions and road-induced changes to soil biogeochemistry and hydrology can lead to shifts in plant composition in calcareous grasslands. Mixed effects models were used to identify relationships between plant community composition and a suite of measured and modelled environmental variables along transects away from roads at eight calcareous grasslands. Ellenberg pH, moisture and nitrogen (N) scores increased nearer roadsides, however, only Ellenberg N scores were associated with their respective measured or modelled values highlighting NO2 deposition as a likely driver of change. Forb abundance and diversity increases nearer roadsides were also associated with NO2 deposition, with increases seen in the abundance and diversity of typical edge species rather than species characteristic of calcareous grasslands. Grazing, removal of invasive species and the use of barriers to intercept transport-derived air pollution may help to reduce the detrimental effects of roads across these diverse but threatened landscapes. |

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.
