Patterns of leaf characteristics, forest structure, tree species diversity, biomass, and productivity across a gradient 3300 m 15.7°C in mean annual temperature Kumaun, the Indian central Himalaya, were summarized compared to values from other similar forests. Throughout elevational gradient, rainfall was high (100—300 cm), but not correlated with elevation. Evergreen 1—yr life—span dominated most transect; above 1800 m, deciduous multiyear evergreen leaves also well represented. Although...
E cological measurements, as traditionally made, represent small areas. However, in response to worldwide concern about environmental quality, ecologists have expanded their focus encompass the earth (e.g., Field et al. 1995, Frank and Inouye 1994, Neilson Marks Wessman 1992). Analyzing predicting processes at scale of biosphere require that information-including data geographic regions biological systems are not well represented widely available basesbe integrated appropriate scale.

Abstract This article draws attention to the significance of Himalayas in relation global climate change, and discusses likely impact warming on ecosystems both upstream downstream regions. Scientific evidence suggests that are at more than average rate. Alpine particularly vulnerable warming, as species occurring near mountain tops will have no space for their upward march. Intensification water stress because warmer temperatures can adversely affect leaf phenology regeneration many...
Leaf dynamics, nutrient (N, P, K, Ca, and Na) changes, retranslocation from the leaves of 13 species were investigated in four representative forest communities Central Himalaya, India. In evergreens temperate regions, with leaf longevities several years, there is negligible movement substances during first year. For by contrast, loss mass beings autumn often continues until summer, when new are formed. The decrease dry this period was 12.3-34.1% maximum mass. concentration N, K decreased...
The Himalaya range encompasses enormous variation in elevation, precipitation, biodiversity, and patterns of human livelihoods. These mountains modify the regional climate complex ways; ecosystem services they provide influence lives almost 1 billion people 8 countries. However, our understanding these ecosystems remains rudimentary. 2007 Intergovernmental Panel on Climate Change report that erroneously predicted a date for widespread glacier loss exposed how little was known Himalayan...
Abstract. Lantana camara shrubland is compared with the adjacent Quercus leucotrichophora and Pinus roxburghii forests to understand changes occurring in net primary productivity nutrient cycling, as a consequence of degradation these forests. The total was 17 t ha ‐1 yr , which similar values reported for forests: 16 ‐ 21 . Total content (N, P) soil L. shrubland: 2932 kg N 111 P, lower than that forest soils.
This paper is concerned with the heavy rainfall episode reported over some locations of eastern parts Uttar Pradesh, India during 16 & 17 September 2021 and associated meteorological conditions are investigated. Each deserves major scientific documentation for improvement in existing knowledge users. Even though it may also benefit general public, as concerns everybody domain. case study will serve above purpose be useful policymakers, disaster managers, response, mitigation. Regarding...
The biomass and net primary productivity (NPP) of 2- to 8-year-old plantations Eucalyptus tereticornis Sm. (= E. hybrid) growing in the tarai (a level area superabundant water) region Central Himalaya were estimated. Allometric equations for all above-ground below-ground components trees shrubs developed each stand. Understorey, forest floor litter fall also estimated from stands. Shrubs appeared first at 5-year-old plantation. vegetation, littermass, tree increased with increase plantation...
With main purpose of developing a coherent baseline information timberline forests Sikkim, Eastern Himalaya, we investigated, (i) forest structure and composition, (ii) regeneration status dominant tree species between treeline, (iii) influence environmental variables in (iv) relationship ecological attributes. The study was conducted along the stretch Dzongri landscape nested within Khangchendzonga National Park (UNESCO's World Heritage Site, 2016), core zone Biosphere Reserve (in UNESCO...

Abstract. This study describes the biomass and net primary productivity of forests Central Himalaya occurring in areas where vegetation ranges from close‐canopy broad‐leaved forest to stunted open‐canopy timberline vegetation. The studied were Acer cappadocicum at 2750 m, Betula utilis 3150 Rhododendron campanulatum 3300 m altitude Himalaya. With rise decreased 308.3 ton/ha 40.5 forest. decrease was less steep, 19.6 ton/ha/yr 10.0 production efficiency leaves (net per unit leaf weight) these...
The developmental stages of 142 alpine plant species were observed during 1984/85 in the grassland site Rudranath bughiyal (30°28′N, 79°20′E; 3250 to 4200 m) Central Himalayan region. The...
