| Abstract | Hypania invalida (Grube, 1860), one of three common polychaete species for the Kuybyshev Reservoir, was found for the first time in the mid-1970s. It recently became a common benthic species, despite its low density and biomass. This polychaete can be found quite often at depths of more than 5 m, in silty deposits, and in communities formed by two dreissenid species (Dreissena polymorpha and D. bugensis), which are the most abundant in zoobenthic communities. The polychaete abundance depends weakly on the abundance of dreissenids in communities. However, the polychaete average body size, abundance, and biomass are the highest in the communities where the dreisssenid contribution to the total biomass constitutes 10.1 to 50.0%. For the last 10–15 years, the average polychaete body weight has tended to decrease; the same is observed for its abundance in the dreissenid communities. The seasonal dynamics of polychaete populations and its reproduction peculiarities are estimated on the basis of data on its abundance and body weight. |

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.
