Environmental Feedbacks of the Subalpine Ecotone Species in the Langtang National Park, Central Nepal Himalaya

Popis výsledku v původním jazyce

An acute sensitivity of ecotone vegetation to environmental changes makes ecotone vegetation dynamics as one of thenprime aspects in vegetation ecology. Understory vegetation of ecotone can indicate the changing environmental conditionsnof the region by showing its own growth pattern, abundance, and assemblages. Our study aims at investigating thencompositional pattern of herbaceous species of a subalpine ecotone in Langtang National Park, central Nepal and analyzingntheir responses to the different environmental factors. We performed multivariate analyses to study species composition, andnfor analyzing individual plant species responses logistic regression was used.nIt was observed that profound variation in the canopy cover and soil organic carbon along the ecotone significantlyninfluenced the species composition of the herbaceous vegetation. Response curve analysis showed the most significantnresponse of eleven least tolerance species to the environmental variables. Gentiana argentea, Geranium donianum, Kobresiansp., Potentilla griffithii, Rubia wallichiana, Rubus nepalensis, Thalictrum chelidonii and Thalictrum cultratum werenparticularly important because these species had narrow amplitude to both the studied environmental variables - canopyncover and soil organic carbon. As these species could be critically sensitive to even minor fluctuation in the environmentalnfactor(s), can be regarded as potential indicator species of the respective environmental variable. These indicator speciesncould be vital in understanding community dynamics of the vulnerable ecotone vegetation within the National Park via theirnuse in long-term assessment of the habitat conditions. Replicated studies at broader scales would further be important fornunderstanding the dynamics of the other ecotone plant communities of Nepal Himalaya.
