| Abstract | This study aimed to document variation in the composition and structure of regenerating woody vegetation along an altitudinal gradient of a rupestrian grassland and to describe the relationship between species and characteristics of the soil. All woody plants with a diameter at ground height of ≤1 cm were collected in seven sampling sites at altitudes between 800 and 1400 m in Serra do Cipó (Minas Gerais State, Brazil). Phytosociological parameters and the Shannon diversity index were calculated and compared using Hutcheson’s t test. Floristic composition was evaluated by nonmetric multidimensional scaling (NMDS) ordination with analysis of variance as a confirmatory analysis, in which the response variables were the axis of the NMDS. Correlation between soil characteristics and vegetation patterns was evaluated with multiple regression models and canonical redundancy analysis. For all analyses, we performed analysis of variation partitioning to decompose the explanation of spatial, soil, and altitudinal variation. A total of 809 individuals of 127 species belonging to 26 families were sampled. Species richness and structure varied among altitudes. Species diversity followed an altitudinal pattern and was higher at lower altitudes. Some soil variables, such as remaining phosphorus, base saturation, and structural components, were more strongly correlated with species distribution than the others. Although variation in altitude leads to changes in the composition of the regenerating woody species, variation in plant communities was determined by a combination of environmental factors, of which soil properties played an important role. |

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.
