Five different communities with similar elevations were taken for investigation. The above-ground biomass samples were harvested as close to the ground as possible. Similarly, below-ground biomass samples were collected from harvesting monoliths (25 x 25 x 30 cm). Aboveground net primary production was determined as the sum of positive changes in biomass and belowground net primary production was calculated as the difference between peak belowground biomass and preceding minimum biomass. The live shoot biomass increased from May till September in all communities except Trachydium roylei and Polygonum, which peaked in August. The dead shoot and litter biomass first decreased and peaked in all communities in October. Belowground biomass first decreased and then increased towards the end of the growing season. The belowground to aboveground biomass ratio ranged between 0.61-3.08. The aboveground net productivity ranged between 454.8-294.3 g m-2, and the belowground net productivity ranged between 346.3-102.4 g m-2.","PeriodicalId":142181,"journal":{"name":"Indian Journal of Forestry","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123077285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Topographic, landcover, physiographic, edaphic and bioclimatic variables were used to predict the potential distribution of these plants in the alpine vegetation zone. Field surveys were conducted to collect occurrence data, and the abundance of species was assessed through rapid mapping exercises. The study found that certain habitat types, particularly Danthonia-dominated grassy slopes, herbaceous meadows, and shrubberies between 3000-4100 m elevations on specific slopes, were preferred by the MAPs. Among the threatened MAPs, Allium stracheyi had the largest potential distribution area (588 km2) with a moderate abundance of 1.7 individuals/m2, while Aconitum balfourii had the smallest potential distribution area (100 km2) with low abundance (0.2 individuals/m2). The results of the MaxEnt analysis identified several significant contributing factors for the potential distribution of threatened species, including aspect, slope, vegetation type, mean diurnal temperature, and precipitation during the wettest months. Based on the potential distribution and abundance data, specific meadows such as Valley of Flowers, Kandara, Ralam, Milam, Tungnath, Panchachuli, and Pindari were identified as priorities for in-situ conservation and management efforts.","PeriodicalId":142181,"journal":{"name":"Indian Journal of Forestry","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128273275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The clones of species E. camaldulensis in IFGTB series performed superior over FRI clones/species of E. tereticornis. The results of the analysis of variance (ANOVA) for mean height and girth increments showed high levels of significance. The results of growth performance indicated that all clones gave superior results for growth indicators as compared to control. On the basis of growth parameters, viz., height, girth at breast height, basal area and tree volume, in IFGTB series, the clones IFGTB 4, 8, 6, 10 and 1 performed superior over other clones, whereas in FRI series, the clones FRI 100 and FRI 124 performed superior over others.","PeriodicalId":142181,"journal":{"name":"Indian Journal of Forestry","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133920575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Internationally acclaimed standard laboratory procedure was followed in the preparation of permanent slides. The qualitative and quantitative wood anatomical characters were studied as per the International Association of Wood Anatomists (IAWA) terminology for hardwoods. Photomicrographs were taken for showing the diagnostic features of each taxon. The selected Salix species had some similar qualitative wood anatomical features along with differentiating characters based on which species can be distinguished from each other. In addition to qualitative anatomical features, quantitative anatomical features also showed significant differences among species. The main differentiating anatomical characters were druses, vessel-ray pits, ray seriation, shape/outline of solitary vessels and vessel frequency based on which identification key was prepared.","PeriodicalId":142181,"journal":{"name":"Indian Journal of Forestry","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127492965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
