Subject: Why is it essential to critically study allied taxa while describing those new to science? A case study based on Lepidagathis keralensis (Acanthaceae)
Keywords: Allied and new taxa, diagnostic characters, Lepidagathis keralensis, plant extinction, taxonomic practices.
Abstract: The effective conservation of a species is feasible only when its taxonomy and ecology are well understood. India is one of the top ten countries in the world, reporting several new species and is also
recognized as a centre of plant extinction. The role of plant taxonomists in the country is considered
crucial. This article discusses one of the most neglected taxonomic practices among Indian taxonomists while describing new taxa. It is done in the context of the field and detailed macro- and micromorphological studies of a newly described Lepidagathis Willd. (Acanthaceae) species from the
lateritic plateaus of the Western Ghats in Kerala as an example. The taxonomy of Lepidagathis keralensis Madhus. & N.P. Singh is also discussed with an updated description and colour photographs for precise identification.

Abstract: We are constantly amazed by various aesthetic and utilitarian services rendered by the members of
class Insecta. Not just services, but they also enlighten us with fundamental philosophies of life. As
an illustration, the metamorphosis of caterpillars to stunning butterflies whispers into our ears the
significance of transformation and hope, ants moving in rows underpins the relevance of teamwork.
They also form an integral component of the food web and act as scavengers. An attempt has been
made to showcase the grandeurs of insects. Above all, the greatest challenge to us is conserving
them as the very existence of insects is obligatory, for humankind will disappear without them

Subject: Issue of enteric methane emissions from Indian livestock
Keywords: Enteric methane emissions, Indian livestock
Abstract: The issue of greenhouse gas (GHG) emissions and its impact
on climate change is a matter of imperative concern at the
global level. Livestock farming has long been a mainstay of
human civilization, providing essential food and other resources to humankind. Ramifications of the livestock industry, especially its effects towards GHG emissions, cannot be
overlooked in this context. While the transport and energy
production industries are in the centre stage for their GHG
emissions, the spotlight on the livestock industry often gets
relegated. However, livestock production too plays a vital
role in contributing to the peril of GHG emissions. Methane
is a potent GHG, which is latent but has a significantly
higher potential than carbon dioxide over a 20-year time
frame. Due to its relatively lower concentration in the atmosphere, its impact often gets underestimated. Therefore, we
must appraise the issue’s intensity, emphasize the dire need
to address the same and initiate proactive measures to mitigate GHG emissions from livestock.

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.

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.
