Observations on phenology of some representative trees, shrubs, under-shrubs and herbs in a subalpine forest of Uttarakhand, western Himalaya were recorded. With the commencement of favorable growth season in April, occurrence of leaf fall was indicatory growth phenomenon in Quercus semecarpifolia, Q. floribunda and Abies spectabilis. However, active(More)
The present study was aimed at characterization of the cellulose degrading actinomycete strain St-1, isolated from soil samples of Patna region in India, on the basis of morphological, cultural, physiological and molecular characterization. Based on morphological and analysis of 16S rRNA sequence, the strain St-1 was identified as Streptomyces griseorubens(More)
The present study outlines an approach to classify forest density and to estimate canopy closure of the forest of the Andaman and Nicobar archipelago. The vector layers generated for the study area using satellite data was validated with the field knowledge of the surveyed ground control points. The methodology adopted in this present analysis is(More)
Four representative species of different growth forms viz., rhizomatous forbs (Rumex nepalensis Spreng.), mat-forming forbs (Plantago major Linn.), stoloniferous forbs (Picrorhiza kurrooa Royle ex Benth.) and prostrate creeping dwarf shrubs (Skimmia laureola Hook. f.) were exposed to CO2 to assess its effect on their growth, morphology and dry matter(More)
Aconitum balfourii (Bruhl) Muk. (Ranunculaceae) is an endangered medicinal plant. Natural populations were surveyed in the northwest Himalaya for population estimation and evaluation of elite germplasm. Vegetation sampling of quadrats was conducted using the vertical belt transect method in areas supporting A. balfourii. Plant density and relative dominance(More)
Studies were conducted on population status and regeneration of Quercus semecarpifolia and Quercus floribunda in a subalpine forest of western Himalaya. Saplings of Q. semecarpifolia belonging to the 51-100 cm size class and those of Q. floribunda belonging to the 101-150 cm size class were well represented in studied subalpine forests. Comparable seedling(More)
The increasing forest fragmentation rate stresses the necessity of conservation of species by restoring their habitat sites. Particularly, endemic species deserve much attention as they show a narrow range of distribution. The present study is focused on the population structure, age gradations, and regeneration status of Pterocarpus dalbergioides Roxb., an(More)
Phytodiversity is affected both by natural and anthropogenic factors and in Island ecosystems these impacts can devastate or reduce diversity, if the native vegetation is lost. In addition to rich species richness and diversity, Island systems are the sites of high endemism and any threat to these ecosystems will consequently lead to loss and extinction of(More)
