| Abstract | Seedling densities and the mortality of fleshy-fruited species under 10 European tall-shrub species and the tree Sorbus aria were analyzed in 10-year-old experimental scrub for one growing season. The mean total densities of seedlings of 18 fleshy-fruited species differed under the different ‘hosts’, being highest under Crataegus monogyna, Viburnum opulus and Rosa canina (24–20 m$^{−2}$); intermediate under Sorbus aria, Rhamnus catharticus, Cornus sanguinea, Ligustrum vulgare and Juniperus communis (17–12 m$^{−2}$); and lowest under Euonymus europaeus, Viburnum lantana and Prunus spinosa (10–9 m$^{−2}$). This ranking was similar for the 11 planted species and for nine bird-dispersed, non-planted species which invaded the site, notably Hedera helix and Solanum dulcamara. Within the experimental scrub as a whole mortality of seedlings differed significantly among species, being highest in those with the smallest number of recruits. Mortality ranged from 94% and 89% for Solanum dulcamara and Viburnum opulus to 26% for Hedera helix and Ligustrum vulgare. The mean mortality across all species of seedlings did not differ significantly between host species, although it was slightly higher under Juniperus and Cornus (56%, 53%) and lower under Viburnum lantana and Rhamnus (42%, 41%). In four species, the mortality of seedlings was significantly higher under conspecific adults. Mean topsoil water content after a dry spell was negatively correlated with the diffuse site factor (DSF). The mean density of accumulated seedlings of the most abundant seedling species (Hedera) was positively correlated with the topsoil water content. Densities of other species showed no strong correlations with either topsoil water content or DSF. The probable factors controlling recruitment are discussed. |

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.
