| Abstract | Competition between managed honeybees and wild pollinators is thought to be a key factor in structuring foraging communities on flowers. The majority of studies have focused on impacts such as floral visitation rates and resource overlap. However, direct measurement of fitness is required to fully assess the impacts of competition. We compared in 2 years the weight and reproductive success of bumblebee colonies located at two sites that were either close to or far from a large honeybee apiary, and which were located in the same landscape and with access to similar floral resources. We found that bumblebee colonies located at the site near the honeybee apiary gained less weight, and produced fewer and smaller queens, in both years than colonies at the site far from the apiary. The ratio of queen weight/size was lower in the colonies near honeybees in 1 year, while males were smaller and offspring sex ratio more male biased in colonies close to honeybees than in those far from honeybees. Proximity to managed honeybee hives was therefore associated with significantly reduced fitness of bumblebee colonies, but studies from many more sites are needed to confirm the effect. |

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.
