Although several ethnomedicinal studies are available from the Himalaya, quantitative studies focusing on protected areas in this region are largely overlooked. In this study, we aimed to document the ethnomedicinal plants of the Overa-Aru wildlife sanctuary in Kashmir Himalaya. We conducted a systematic field survey in the study area during 2020 – 2021 to collect primary data from 110 participants through semi-structured interviews and questionnaires. The data was analyzed using quantitative indices and Pearsonʼs correlation. We recorded 64 plant species used against 8 human disease categories, including some first-time reports from the region. Asteraceae and Lamiaceae were the most dominant families and herbs were the dominant growth form. The most common plant part used were leaves, and the main method of preparation was decoction. Plant species with the highest r...

Research paper thumbnail of Growth dynamics and Resource allocation of Bistorta amplexicaulis (D. Don) Greene: an alteration across different habitats and altitudes

Ethnobotanical studies have revealed that this particular species is used to treat fractures, muscle injuries, heart problems, abnormal leucorrhoea, menorrhagia and inflammation of the mouth and tongue. The current study aimed to determine the variation in growth traits and fluctuations in the allocation patterns with respect to different habitats across the altitudinal gradient. In order to adapt to unpredictable and stressful conditions at higher altitudes, phenotypic plasticity plays a crucial role. Our findings revealed considerable variability in the phenotypic traits, indicating that altitude has a defined effect on this specific species’s morphology and reproductive traits. Low altitude plant populations of Kashmir University Botanical Garden (KUBG), Dara and Tangmarg were more robust and taller (98.4±2.36, 83.58±2.69 and 74.08±1.59 cm, respectively) than the populations of Pissu top and Ban...

Research paper thumbnail of Variability in morphology, phytochemicals, and antioxidants in Polygonatum verticillatum (L.) All. populations under different altitudes and habitat conditions in Western Himalaya, India

All. is one among eight species of Astavarga group of plants known for its vitality strengthening properties and used in different herbal formulations. However, systematic investigation on morphology and antioxidant phytochemicals in relation to different environmental variables like altitude and habitat conditions is poorly available. The present study reveals significant (p < 0.05) differences in structural and functional attributes among sixteen different populations of P. verticillatum in West Himalaya. Among the different populations, plants growing in moist habitat and oak forest exhibited maximum plant height, leaf number, biomass and phytochemical content (total phenolics, tannin, and flavonol). Antioxidant activity using 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) and 2,2-diphenyl-1picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) positively (p < 0.05) correlated with altitude. Presence of strong antioxidant and DNA damage prevention activity of the species validate its use as vitality strengthening and anti-aging properties. Identified suitable altitude, habitat conditions, and forest types can be utilized for reintroduction of species in to suitable agro-climatic condition. This will also help in obtaining higher quality produce and management practices for conservation of this species.

The current study is the first of its kind, carried out to find the impingement on growth dynamics of the plant under study along various altitudinal inclines and habitats. Extensive field surveys were conducted during the years 2020-2021 to assess the distribution and phenotypic attributes of Phlomis cashmeriana. Three natural sites viz, Jawahar tunnel, Hillar naar, Daksum and one control population at KUBG were selected for the present work. Morphological characteristics of species were noticed to be varying extensively under different scopes of environment. Plants thriving at lower altitudes (KUBG) were found to be growing vigorously and taller. However, the opposite scenario was observed in plants growing at higher altitudes (Jawahar tunnel). KUBG and Daksum were reasonably found to be better habitats for the growth of Phlomis cashmeriana as ...

Research paper thumbnail of Meiotic Bottlenecks Compromises Reproductive Success by Impairing Pollen Fertility and Seed Set in Swertia thomsonii C. B. Clarke—An Important Endemic Medicinal Herb of Western Himalaya

The presence of meiotic bottlenecks directly or indirectly influences the reproductive success of a plant species. The present study records chromosome number, male meiotic behavior, seed set, pollen viability, and pollen germination in two populations of Swertia thomsonii, an important medicinal plant of Himalaya. The chromosome count recorded in both accessions was 2n=2x=26, however; chromosomal abnormalities (21.23 and 4.31%) were recorded in population 1 (Pop-1) and population 2 (Pop-2), respectively. These include chromosomal stickiness, out of the plate, formation of laggards, abnormal spindles, bridges, multipolarity, and polysporads. These meiotic irregularities compromise pollen viability, pollen germination, and seed set of species. The possible cause for these recorded meiotic abnormalities was cold stress as the species grows in temperate or sub-alpine regions with cold climatic conditions. Another possible reason might be the presence of heavy metals in the soil more than permissible limits, which was determined by soil sample analysis. Therefore, these findings along with other reproductive and ecological studies can aid in the development of successful conservation and management strategies for this medicinally important plant species.

In this study we analyzed the phytosociological and soil characteristics of Phytolacca acinosa communities and their correlation. 110 quadrats were laid across ten randomly selected sites in Kashmir Himalaya, India. Soil analysis was done using standard protocols. Overall, 161 species were recorded, belonging to 128 genera and 49 families. The species richness (SR) ranges from 27 to 83. Highest IVI was recorded for Poa angustifolia (60.06) and least for Berberis lycium, Abies pindrow, Plectranthus ragosus, and Ailanthus altissima (0.37 each). P. acinosa showed 100% random associations with other plant species. Soil properties varied significantly across the selected sites. Significant positive correlation was found between species richness (SR), Organic matter (OM) (r = 0.79), Organic carbon (OC) (r = 0.79) and Shannon–Wiener index (...

It is essential for the government and health management system to monitor the districts affected due to COVID-19. The main objective of this study is to ascertain and categorize the COVID-19 affected districts into real clusters based on similarities within a cluster and differences among clusters in order to imply standard operating procedures (SOPs) policies, decisions, medical facilities, etc. could be improved for reducing the risk of infection and death and optimize the deployment of resources for preventing subsequent outbreaks.

Research paper thumbnail of Impact of Habitat Variability on Phenotypic Traits and Seed Germination Performance of Euphorbia helioscopia L.; a Case Study from the Kashmir Himalaya, India

(Euphorbiaceae), is an important medicinal plant species of the Himalayan region. The species showed wide variability in its phenotypic traits under different environmental conditions. The purpose of this study was to determine the impact of elevational gradient on the morphological traits and reproductive features of the species. The plants grown in the Kashmir University Botanical Garden were more vigorous and taller than the plants of high-altitude sites. Principal component analysis (PCA) revealed that the habitat of KUBG and Kangan (Ganderbal) were comparatively facilitated the growth of E. helioscopia. The regression analysis showed a positive correlation between various morphological traits. Our attempted results highlighted an elaborated account of the variation of phenotypic traits and seed germination performance in response to different environmental conditions along an elevational gradient.
