| Abstract | Flower visitors often fly among plants of the same species more often than is expected from plant frequency and distribution, a behavior known as flower constancy. Because of its implications for the evolution of floral traits, whether flower constancy is associated with perceptual stimuli, reward value, and/or flower handling skills has been debated by many authors. However, it remains unknown whether flower handling skill has a substantial influence on flower constancy because flowers that require different handling skills generally also differ in their appearance (i.e., shape). We investigated the foraging type constancy of Bombus terrestris workers that foraged flower patches consisting of two (Trifolium pratense and Trifolium repens) or three (T. pratense, T. repens, and Lotus corniculatus) plant species. In these flower patches, individual bees foraged T. pratense flowers by either one of the two foraging modes that require different foraging techniques (legitimate foraging versus nectar robbing). Behavioral and pollen load analysis indicated that bees sometimes switched their foraging types between legitimate visits to T. pratense and visits to T. repens and between nectar robbing on T. pratense and visits to L. corniculatus, though they rarely switched between other combinations of foraging types. These results indicate that factors other than perceptual stimuli and spatial distribution of plants affected foraging type constancy. After considering other factors, such as the rewards and the sizes of individual foragers, we argue that handling skills required to forage flowers affected flower constancy observed in this study. |

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.
