| Abstract | In this study the nectar-gathering behavior of population of virtual bees is observed during visits to a field of simulated flowers over several hundred generations. The object of the study is to see if floral constancy evolves in the virtual bees. Floral constancy, observed in real bees, is the tendency to harvest nectar from only one type of flower. Flowers can only reproduce if they have received the proper pollen type from a visiting bee and so floral constancy is potentially of substantial importance to flowering plants. The virtual bees are evolved for 250 generations and evaluated for floral specialization. Floral specialization is defined as the average of the maximum visits to one flower type divided by the total number of flower visits. The initial hypothesis was that populations with flowers that had nearly equal amounts of nectar available to the bee would not specialize, but populations with flowers that had a large difference in obtainable nectar would specialize in the flower with more nectar available. Although populations with a choice between nearly equal returns stabilized at non-specialization, the other populations did not behave as expected. Populations that were given one flower with nearly no available nectar (less than 0.1000) and a flower with a larger amount of nectar available specialized in the flower with nectar, but when given a choice between flowers with any procurable amount of nectar greater than 0.1000, the populations eventually stabilized at non-specialization. |

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.
