| Abstract | The conversion of old-growth into secondary forest changes profoundly the community structure of most plant life-forms, including the communities of terrestrial herbs. Here, we verify how herb communities are affected by environmental variables of old-growth and secondary stands of South Brazilian Atlantic Forest. We identified all herbaceous species and estimated their frequency and cover in 16 plots of 6 × 6 m in each forest type. We used the structural characteristics of the tree component (i.e., basal area, density, average height and canopy openness) and soil parameters as environmental variables of each forest. Results showed that old-growth and secondary forests have distinct herb composition, with the later showing higher plant cover and species diversity. Canopy openness and soil parameters explained part of the variation in herb composition between forests. Herb cover and richness responded positively to soil fertility in both forests, and in secondary forest these two descriptors were also positively correlated with canopy openness. The abiotic differences between forests allowed the establishment of herbaceous species with different ecological requirements, especially in the secondary forest, marked by input of species typically found in disturbed environments. These species contribute to the higher cover values and species richness in secondary forest. Our findings suggest that changes in environmental conditions in a forest substantially change the herb community. Because of their importance as environmental indicators, herb communities can contribute to a better understanding of successional patterns in the Atlantic Forest. |

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.
