| Abstract | An important feature of seed dispersal mutualism is the differentiation of dispersal-related seed traits (dispersal syndrome), which potentially contribute to partitioning of both seed dispersers and regeneration sites among sympatric plants. Yet, the selective factors underlying the diversity in dispersal syndromes are largely unknown. The differential requirements for seed dispersal distances are often proposed as a main factor in plant adaptations to disperser animals. Focusing on two sympatric ant-dispersed sedges Carex lanceolata and Carex tristachya (Cyperaceae), we tested the association of the adaptation to different dispersers with requirements for seed dispersal distances. We found that C. lanceolata was more frequently dispersed by the large ant Formica japonica (which had relatively long dispersal distances compared with other smaller ants) than by C. tristachya, and this was caused by the higher seed attractiveness of C. lanceolata to F. japonica. Pot experiments manipulating adult-to-seedling distances showed that isolation from conspecific adults only benefited C. lanceolata seedlings, and C. tristachya seedlings were not affected. These results support the importance of differential requirements for seed dispersal distances as a factor underlying the diversity in dispersal syndromes among animal-dispersed plants. |

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.
