| Abstract | Coastal sand dunes are a hostile environment for forests. Little is known about the composition and diversity of the bacterial community in forest soils established on sand dunes. This study examines the soil bacterial community in the upland and lowland Casuarina and lowland Hibiscus successional forests in a coastal sand dune ecosystem. The 16S rRNA gene clone libraries were constructed to analyze the structure and diversity of communities. The Acidobacteria and Proteobacteria predominated in the sand dune forest communities, but the proportions of some phylogenetic groups differed among three communities. Some Actinobacteria- and Bradyrhizobium-related clones were only present or abundant in Casuarina forest soils. Because Casuarina could support a symbiotic, N2-fixing soil bacterial community, the composition of the microbial community may reflect its potential roles in the nitrogen budget and the effects of vegetation. Based on the diversity indices, the lowland Casuarina soils had the least diverse community, and the upland Casuarina community was the most diverse. Compared to an inland natural forest community, the dune communities were more diverse and had different proportions of abundant bacterial groups from those in the inland soils. The distribution of the abundant operational taxonomic units also differed among coastal and inland forests. The topography and vegetation type could affect the soil bacterial community composition in sand dune forests. The high diversity of soil bacterial community may be a result of the succession phase of the sand dune ecosystem. |

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.
