Subject: Economic Contribution of Wild Edible Minor Fruits to the Forest Fringe Tribals - A Sustainable Alternative Livelihood Approach
Keywords: Economic Valuation, Livelihood Option, Minor Fruits, Tribal Community.
Abstract: Valuation of tropical dry deciduous forests of eastern lateritic part of India is mostly based on economic appraisal of its wood stock. Occasional assessment often overlooks the economic potential of non-timber benefits like wild edible minor fruits (WEMFs) which have a wide subsistence use even for cash income. Present study deals with the ethnobotanical information, spatio-temporal distribution along with estimation of economic contribution considering annual productivity and utilizations of WEMFs in the two sampled forests of eastern lateritic part of India from where a major tribal community (Santal) gets benefit. Annual production and utilization was performed considering different factors associated to the quantum of extraction. A new comprehensive economic model was developed to estimate the net annual economic contribution per Santal family by WEMFs. A higher production peak of WEMFs in alternative year was noted along with Clump distribution and specific habitat preference. Net value of revenues - from these WEMFs was estimated to be Rs. 772.86 ± 76 family-1 year-1 which presently contributing 3.74% of their total annual income. Forests of eastern lateritic part of India have a strong potentiality to produce WEMFs that may be helpful in generation of alternative livelihood option to the local tribals through entrepreneurship development.

Subject: Leaf and Shoot Growth Characteristics of Abies pindrow and A. spectabilis of West Himalaya
Keywords: Abies spp., High Altitude, Leaf and Shoot Characteristics, West Himalaya, Climate Change.
Abstract: In this article leaf and shoot growth characteristics of two fir species (A. pindrow and A. spectabilis) found in the high-altitude zone of Tungnath (Uttarakhand) are described with an objective to identify them easily due to their almost similar morphology. The mean height of A. pindrow trees was markedly greater than A. spectabilis (40.3±1.80 vs. 27.7±1.15 m), and the tree height declined but tree CBH increased with the increasing altitude. Both shoot diameter and number of leaves per shoot were higher in A. spectabilis for both leader (mean= 4.2 vs. 6.0 mm) and lateral shoots (mean=3.1 vs.3.88 mm). The number of leaves per shoot in A. spectabilis (mean= 146) was two and half times more that in A. pindrow (mean= 65). The leaves of A. spectabilis were comparatively smaller (length= 2.50 cm), narrower (width= 0.19 cm) and thinner (thickness= 0.25 mm) than the leaves of A. pindrow (length= 4.6 cm), narrower (width= 0.23 cm) and thinner (thickness= 0.38 mm). Leaves (needles) of A. pindrow are acute and bifid at apex, and A. specatbilis leaves are rather smooth at apex and have two greyish bands on either side of shallow mid-rib. Leaf mass (0.006 vs. 0.01 g/leaf) and leaf area 2 (0.48 vs. 1.0 cm2 /leaf) was also higher for A. pindrow. The increasing leaf thickness with altitude has important implications for understanding the ability of these two important fir species to harvest sunlight and grow in the cold environment at high altitude to devise an appropriate forest management practice in the era of climate change.

Keywords: Girth Size, α- and β- Santalol, Indian Sandalwood, Oil, Variability.
Abstract: Santalum album L. is commonly known as Sandalwood or Indian Sandalwood and categorized as 'vulnerable' by the International Union for Conservation of Nature. Variation for oil and its major constituents i.e., α- and β- santalol of the Sandalwood trees with wide range of tree girth from two different locations in the Uttarakhand state has been attempted. Sandalwood core samples were collected from twenty trees of different girth size ranging from 34 to 152 cm. Extraction and estimation of sandalwood oil from the core samples was carried out by using solvent extraction and gravimetric analysis methods respectively. Whereas α- and β-santalol content was estimated from the extracted oil by using Gas chromatography/Mass spectrometry technique. Estimated oil content ranged from 0.45% to 3.07% while α- and β- santalol content varied from 40.5% to 55% and 16% to 26% (w/w) respectively. Although considerable variation in oil and santalols content exists, but no significant relationship between tree girth, oil, and santalols content was observed. Therefore, sufficient care has to be taken while selecting superior genotypes of Sandalwood tree from study areas.

Subject: Thermal Modification of Bamboo : A Chemical-Free Processing Technique for Improving the Properties and Performance of Products
Keywords: TM Bamboo, Bamboo Timber, Dimensional Stability, Decay Resistance, LBL, BSL.
Abstract: Thermal modification is one of the ecofriendly alternative processing techniques for improving various properties of bamboo including dimensional stability and decay resistance. The heat treatment protocols for producing thermally modified (TM) bamboo have been worked out in the laboratory for different species. The TM bamboo exhibited improved properties particularly lower shrinkage and swelling, higher water resistance, darker brownish colour and enhanced decay resistance against fungi and borers. When bamboo is subjected to heat treatment temperatures above 200°C for longer durations (>8 hours), the flexural strength is found to be adversely affected. By thermal processing, not only decay factors of bamboo are eliminated but dimensional stability and resistance to moisture related problems are also improved. TM bamboo with improved aesthetic and quality parameters may be used for production of certain value-added “green products”. A few composite boards were produced successfully in the laboratory using TM bamboo. The bamboo culms of required dimensions were thermally modified and converted into thin strips or crushed bamboo, which can be processed further into sturdy composite panel products such as laminated bamboo lumber (LBL) or bamboo strand lumber (BSL) or so called “bamboo timber”. Thus, thermal modification of bamboo may be considered as an ecological alternative to preservative chemical treatments. The thermally modified bamboos may be used for different valued-added products such as furniture, flooring tiles, bamboo boards and strip-based panel products in structural and non-structural industry sectors. Through successful implementation of up-scaled processing, this technique may lead to prospective business opportunities and bamboo-based industry of the country may utilize TM bamboos for production of various life-style products.

Abstract: The present research attempts to characterize the morphological and germination behavior of a promising fodder species Sesbania grandiflora L. (Agast) under nursery conditions. Experiment was carried out at the nursery of the Forest Research Center for Eco-Rehabilitation (FRCER), Prayagraj, Uttar Pradesh, during April 2021 and different germination parameters viz, germination per cent, survival per cent, germination capacity, germination energy, vigour index, mean daily germination and mean germination time along with seed morphological parameters were studied. Early germination from the medium-sized seeds of S. grandiflora proved to be significant under nursery conditions. A good germination per cent (83.42%) and low mean germination time (14.19 days) indicates an early and rapid germination of S. grandiflora under nursery conditions. Such an investigation may help nursery managers to produce seedlings of species for fodder availability during lean period.

Keywords: Altitude, Biomass, Net Primary Productivity, Kumaun Himalaya.
Abstract: The present study was performed in the forest of Kumaun Himalaya present along the altitude as to determine the biomass storage and NPP of the forests. For this purpose, a total of 150 plots were placed at 15 different sites by following plot sampling method. Allometric regression equations were used for the calculation of tree biomass and NPP, which were previously developed for the similar forests and similar tree species of Himalaya by different workers. The biomass value of all the five forests ranged from 156-918.36 t ha-1 and NPP varied between 10.70 and 20.30 t ha-1 yr-1. Low biomass value was reported at middle altitude (chir-pine and banj-oak forest) and lowest altitude (teak forest) as compared to the high-altitude forests. However, all the forests showed high net primary productivity. The regression analysis showed a positive correlation of biomass with NPP (r2 =0.595). No relationship was seen between altitude and biomass and altitude and net primary productivity. In fact the entire elevation range supports good productivity and biomass. It was also noticed that expansion of chir-pine forests towards the banj-oak forest was responsible for the low biomass of banj-oak forests. Banj-oak forests at this elevation are considered to be the soil binder forests which bind the soil and stop landslides. However, the chir-pine expansion in banj-oak forest area is facing tremendous loss in its forest vegetation.

Abstract: This study is aimed at evaluation of ecological and economical value of Subsidiary Silvicultural Operations (SSOs) in Sal Forest of Jharkhand, by measuring its effects in terms of Ecosystem Services (ES). Data like plant height and girth etc. were collected, from 18 samples and 18 control plots, spread over 3 Agroclimatic Zone, for three models of SSOs. Using the collected data, parameters like wood volume, Biomass, Shannon Wiener Index (H’), Regeneration status and Soil conserved / ha. were generated. Comparative analysis between sample and control plot shows, SSOs where practiced has led to alter significantly, the productivity and biodiversity of forest. In sample plot wood volume growth assessed was 107 m3 /ha.; Biomass growth 54 m3 /ha, Carbon content 27m3 /ha. Regeneration percentage as calculated 44.45%. Shannon Wiener Index (H’) was found 1.39 and the average of the same for control plots was found to be; wood volume 61.53 m3 /ha.; Biomass 20.11 m3 /ha., carbon content 10.05 m3 /ha.; Regeneration percentage 28.51% and Shannon Wiener Index (H’) 1.09/ha. Thus, in general, SSOs have a positive effect on all the parameters of ecosystem services. Soil conservation effect is found highest in “Northern dry mixed forest” i.e., 21.1 m3 /ha. Subsequently 16.57 m3 /ha in mixed moist and dry deciduous forest and lowest 13.55 m3 /ha. in dry peninsular Sal Forest. All the factors like wood volume, biomass, and carbon content, Shannon Wiener Index, regeneration status, soil conservation are important measures for sustainability of any given ecosystem. Therefore, SSOs need to be 1promoted to ensure, conserve and increase forest productivity ultimately, achieving sustainable Forest Management, like soil conservation, natural regeneration and biological diversity etc. Study also evaluated the various ES of Forest in terms of monetary value and has found that per hectare enhancement of Rs. 225838 happened in ES NDMF, RS. 324746 in MMDDF and RS. 385120 in DPSF measured by difference between sample and control plot. This gives very significant hope when the same is analysed at ̒ ̒ Forest type level. for this efficacious intervention i.e., SSOs the result showed that in Model no.3 of SSO is the best and dry peninsular Sal Forest of Jharkhand as compared with Model no.1, 2 and forest sub type similarly for NDMF, MMDDF.

The present study is carried out by using geospatial technology as an attempt to Analyse the land use and land cover change over a period from 1973 till 2022.The geospatial technology is being used as a timely and cost-effective way to carry the study as the site remained inaccessible during the long period of insurgency and no adequate database is readily available. Results indicated that there has been significant decrease in the grassland areas, rise in encroachment and changes in the river coarse inside the park.

Subject: Neutral and adaptive genetic variation in Indian snow leopards, Panthera uncia
Keywords: Adaptive evolution, balancing selection, captive breeding, genetic diversity, major histocompatibility complex.
Abstract: In this study, we reveal patterns of genetic variation in snow leopards (Panthera uncia) by combining neutral (mtDNA, microsatellites) and adaptive (MHC II-DRB) genes. We collected 56 faecal samples from three locations in India. We observed moderate levels of microsatellite diversity (N = 30; A = 5.6; HO = 0.559). Nine unique MHC II-DRB sequences were identified in four snow leopard samples, of which 8 were novel. We found low levels of polymorphism in MHC class II-DRB exon, which was higher in captive (VA = 9.4%) compared to wild individuals (VA = 7.8%), likely as a result of a population bottleneck.

Title: 26Al–26Mg isotopic studies in some calcium–aluminium-rich inclusions and chondrules from unequilibrated chondrites

Subject: 26Al–26Mg isotopic studies in some calcium–aluminium-rich inclusions and chondrules from unequilibrated chondrites
Keywords: Calcium–aluminium-rich inclusions, chondrules, early solar system relative chronology, short-lived now-extinct radionuclide, solar system
Abstract: Calcium–aluminium-rich inclusions (CAIs) and chondrules are the oldest dated components of chondrites. They record the events and processes during the formation and early evolution of the solar system in their morphology, mineral phases and isotopic compositions. 26Al–26Mg isotopic systematics of two CAIs from Leoville (CV3.1-3.4), two chondrules from Queen Alexandra range 99177 (CR3.00), one mega chondrule from Semarkona (LL3.00), and a plagioclase rich chondrule from Chainpur (LL3.4) were carried out to understand the formation processes of these rare kinds of objects and to obtain constraints on early solar system events and processes. Petrographic and isotopic properties of Leoville CAI 1 (Type B2) suggest its formation c. 0.1 Ma after typical non-igneous CAIs characterized by the canonical ratio of 26Al/27Al = 5.25 × 10–5 , from a partial melt heated to a maximum temperature of ~1420°C and cooled slowly at ≤0.5°C/h. Leoville CAI 3 (Type A) plausibly formed early within 1 Ma of the canonical CAI value and subsequently experienced parent body aqueous alteration. The analysed chondrules did not yield significant 26Mg excess due to their small Al/Mg ratio or resetting by secondary processes.
