ABSTRACT Herbaceous flora along human-impacted landscapes in the agrestal-ruderal matrix from Manipur, North East India revealed a decrease in richness and diversity from agrestal to ruderal sites. However, the co-dominance and evenness showed the opposite trend in general. The study explored the mutual feedback mechanism between urban-rural landscapes and its impact on the composition, structure, and patterns of vegetation diversity. Studying the diversity patterns and their causes is beneficial for understanding the formation and maintenance mechanisms. This study selected four sites in NE India and conducted field research using uniform sampling methods. The composition, diversity pattern, and driving factors of vegetation were analyzed; soil phosphorus and soil reaction contributed relatively better, while soil nitrogen had a lower negative contribution. The contribution of moisture was found to be lower in distinguishing the two groups of vegetation. The increase in species richness in agrestal sites appeared to be due to the presence of r-strategists capable of rapid multiplication and dispersal, as they can make the best use of available resources. |
