Keywords: Arboreal species, Environmental impact, Northeast India, Phenophase, Tree
Abstract: Phenological studies provide a better understanding in the periodicity of phenophases in various seasons and relationships between the species and environmental factors. This paper presents the phenology of 12-timber yielding tree species in relation to rainfall and temperature. A total of 36 matured individuals representing 12 tree species were monitored for phenology over a period of three years from 2017 to 2019 in Borail Wildlife Sanctuary, Assam, India. Phenological phases like period of leaf abscission, leaf initiation, leaf growth, flowering, fruiting, seed dispersal and germination were recorded fortnightly. Various environmental parameters like precipitation, temperature, seasonality, were found to play crucial roles on the phenology of the tree species. Relationship between various phenophases and environmental factors was examined by using Spearman's rank correlation coefficient. Leaf abscission manifested significant negative correlation with maximum and minimum temperature and rainfall, whereas the remaining phenophases viz. leaf growth, flowering, fruiting and seed germination were shown significant positive correlation with temperature and rainfall for all the three years. The findings from this study can be utilized for management and conservation of the timber resources of the sanctuary in a scientific and sustainable way.

Subject: Carrying Capacity of Tree Fodder Species in Silvipastoral Systems in Himachal Pradesh, North Western Himalaya
Keywords: Agroforestry, Carrying capacity, Himachal Pradesh, Productivity, Tree fodder, Silvipastoral system
Abstract: The primary woody elements of the silvipastoral system, fodder trees are crucial for providing fodder for animals, particularly during dry seasons when herbaceous forage is unavailable. Along with this the leaf fodder from trees also provides fuel wood as a by-product to local communities. In Himachal Pradesh, there is a net shortfall of green fodder (26%) and dry fodder (54%) due to which the livestock population is decreasing continuously for the last two decades. Increasing the production of fodder per unit of land area is one of the potential options for meeting livestock fodder needs. Considering the huge potential of tree fodder species in livelihood security of Himalayan communities, present study was conducted in 12 representative villages of all four agro-climatic zones of Himachal Pradesh. The present study revealed that there is a great disparity between the carrying capacity of tree fodder species in existing silvipastoral systems of Himachal Pradesh. The tree forage yield data showed considerable variation in forage yield varying from 169.74 to 2310 kg-1 ha-1 year . Maximum carrying capacity was recorded in Grewia optiva (0.823 ACU ha year ) with a capacity to feed livestock size (325.88) in Banalgi, Solan (zone-II). However, minimum carrying capacity was recorded in Bauhinia variegata (0.059 ACU ha-1 year-1 ) with a capacity to feed livestock size (16.21) in Jogipanga (Una) zone-I. Among all studied sites Shiun Khas (Kangra), Kundi (Chamba), Naun (Mandi), Jarsahi (Shimla), Keela Kalanj (Sirmaur), Muling (Lahaul & Spiti) and Bhakra (Bilaspur) has high livestock in comparison to carrying capacity. If this pattern continues, the available fodder trees will come under high pressure which will impact the long-term sustainability of silvipastoral land use systems in the future. Therefore, for the sustainable management of silvipastoral land use systems assessment of tree forage carrying capacity is very important.

Subject: Delineation and Mapping of Riverine Wetlands in the Middle Ganga River using Geospatial Technology
Keywords: Riverine Wetland, Floodplain, Habitat, Biodiversity, Mapping.
Abstract: The wetlands are natural sink of pollutants and provides ecosystem services worldwide. Rapidly declining water resources is a global concern, underscored by international conventions such as the Ramsar Convention on Wetlands. The riverine wetlands are located at river floodplain and seasonally connected with the main stem river. Delineation and mapping of these wetlands are important to visualize their distribution pattern. We conducted the study in the middle Ganga River using geospatial techniques to delineate and map riverine wetlands. Result shows the wetlands are distributed along the active river channel in the Ganga River floodplain, which are seasonally connected with the Ganga River in monsoon. The wetlands are replenished with nutrients during fluvial connectivity. Wetlands are delineated and mapped (n=788) using Landsat 8 OLI satellite image by Modified Normalized Difference Water Index (MNDWI) by separating the water and land area using green and short wave infrared spectral bands of satellite image. These wetlands are home to various aquatic and water associated avian species, amphibian and reptiles. Conservation measures for these riverine wetlands are essential for sustainability of wetland ecosystem and wetland inhabiting flora and fauna and rejuvenation of the Ganga River system. Some of the wetlands are declared as protected area and Ramsar conservation sites, whereas more wetlands are need to be conserved under national conservation authority to conserve their natural integrity and to protect its biodiversity. This study provides insights and framework for freshwater habitat management for aquatic biodiversity.

Abstract: If we search the available scientific literature with ‘monsoon’ as the search term, we will be flooded with literally thousands of papers as search results. On the contrary, if we look for books about the monsoon, we would face a drought with just a few titles displayed. The bestseller so far has been Alexander Frater’s travelogue Chasing the Monsoon, which he wrote in 1991 and is now available in its 21st edition. The other most popular book has been The Monsoons by P. K. Das, published by the National Book Trust India in 1968. It is a science book written with the lay reader in mind, and has since been updated four times and translated into several languages. For the monsoon researchers, however, whether in India or elsewhe the definitive book has so far been Southwest Monsoon by Y. P. Rao, published in 1976 as a monograph of the India Meteorological Department.

Abstract: Trees of Bangalore by K Sankara Rao in two volumes is a most attractive, indeed charming, coffee table book focusing on not just flowering trees, but also shrubs, woody climbers, canes, palms and cycads of the city. It covers a total of 795 plant species, each with a number of photographs, a careful description of the morphology, and English, Kannada, and often Hindi and Sanskrit names. Technical terms used in the morphological descriptions are carefully explained with the help of not just verbal, but also a 22-page pictorial glossary with over 260 photographs. This pictorial glossary is itself a feast for the eyes for any plant lover. There are other books on trees of various cities such as Delhi and Mumbai, but none comes close to this book in the wealth and clarity of the information. The 795 species have been recorded from the natural dry deciduous forest of the Bannerghatta National Park, LalBagh Botanical Garden, a number of institutional campuses such as that of the Indian Institute of Science, Foundation for the Revitalisation of Local Health Traditions and the University of Agriculture Science. This is supplemented by records of trees of some sacred groves and those associated with temples, as well as around the old villages, along streets, in business places, and in house yards.

Abstract: The frequency and intensity of landslides in the Western Ghats of Maharashtra, India, have increased. The present study examines the unprecedented series of landslides in the Choravane watershed in July 2021, where 94 landslides were triggered by prolonged and intense rainfall. Many occurred in undisturbed forested areas, indicating that the landslides are not always associated with human-modified slopes. Our findings highlight the role of extended rainfall, distinctive lithology of the Deccan Volcanic Province and groundwater dynamics, particularly subsurface saturation and pore pressure, in landslide initiation. These insights have implications for hazard prediction and mitigation.

Subject: Authentication and trade of true cinnamon: need for regulation and promotion of sustainable cultivation
Keywords: Authentication, Ceylon cinnamon, cinnamaldehyde, Cinnamomum verum, coumarin, trade regulation.
Abstract: Humans have been incorporating spices into their diets for centuries. Initially, spices served to mask unpleasant flavours and odours in food, but over time, they became essential for enhancing taste and aroma. Cinnamon has been one of the most coveted spices globally for thousands of years, following black pepper. True cinnamon comes from the bark of Cinnamomum verum, a species native to Sri Lanka and often referred to as ‘Ceylon cinnamon’. Due to the limited availability and ever-growing demand for Ceylon cinnamon, many similar-looking species from the Cinnamomum genus are falsely marketed as genuine cinnamon. This practice raises health concerns because these substitutes often contain coumarin, a potentially harmful compound. Consequently, there is a pressing need to ensure proper identification and regulation of cinnamon in trade to protect consumers and uphold quality standards.

Abstract: The present study aims to explore the possible association pattern of receptor activator of nuclear factor kappa B (RANK) gene variants (rs 35211496 and rs 1805034) with its circulatory level and bone mineral density (BMD) in North Indian postmenopausal women. In this case-control study, we recruited 165 postmenopausal osteoporotic women as cases (age 54.44 ± 6.00) and 165 healthy postmenopausal women as controls (age 54.47 ± 6.46). BMDs were taken in all subjects using dual energy X-ray absorptiometry at different skeletal sites, and genotyping was carried out using polymerase chain reaction and the restriction fragment length polymorphism method. RANK serum levels were also assessed in all enrolled subjects by enzyme-linked immunosorbent assay. Findings from the present study indicated that subjects with homozygous mutant TT genotype of rs35211496 (NC_000018.10 : g.62354528C > T) and rs1805034 (NC_000018.10 : g.62360008C > T) showed significantly low BMD at forearm, lumbar spine, hip and femoral neck and increased RANK level as compared to CC and CT genotypes. Furthermore, at rs1805034, a significant difference was noted in the frequency of RANK genotypes and alleles among osteoporotic cases and controls (P = 0.021; 0.005) respectively.

Abstract: A study on Basmati rice variety differentiation was carried out in two districts of Haryana, using Sentinel-1 SAR and Sentinel-2 MSI time series data and a Random Forest (RF) classifier on the Google Earth Engine cloud computing platform. The fortnightly composite stack of VH-VV difference and Sentinel-2 multispectral bands and their Red-edge indices, Chlorophyll Index (CIgreen and CIred-edge), was analysed. Basmati varieties could be distinguished into long- and shortduration and early Basmati. The accuracy of the RF classifier model was validated by computing the AUC and receiver operating characteristic curves. AUC was > 0.9, ensuring the best model fitting and high accuracy. The results revealed that long-duration Basmati varieties are being replaced by shorter-duration varieties.

Abstract: The carbon dioxide (CO2) emission reduction technology has the limitation of high energy consumption, and the development of new and efficient capture media is a new way to achieve green and high-value utilisation of CO2. However, ionic liquids (ILs) have attracted the attention of researchers as a novel capture medium. In this study, Aspen Plus software was used to examine the process of capturing CO2 from flue gas of coal-fired power plants using ILs. The physical properties of 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim][BF4]) were analysed using known experimental data, and a process flow for physical absorption of CO2 was established. Based on the established full process model, a sensitivity analysis was conducted on the absorption tower and flash tank. The process simulation results showed that increasing the number of absorption tower plates and the lean liquid flow rate benefits CO2 absorption. The optimised absorption pressure is 3.0 MPa, the number of trays is 15, the lean liquid absorbent flow rate is 500 kmol/hr, the lean liquid feed temperature is 50°C, and the optimal operating conditions for the flash evaporation tank are a recovery pressure of 0.3 MPa and a recovery temperature of 150°C. The calculation of direct equipment investment cost in the process shows that with the increase of lean liquid load, the investment cost of all equipment except for the reboiler increases.

Keywords: None
Abstract: A pair of breeding adult Western Yellow Wagtails (Motacilla flava) was recorded on 2 May 2025 at 07:45 a.m. in Jodhpur, Rajasthan, within the Thar Desert landscape. The Western Yellow Wagtail is a small, slender passerine (body length 15–16 cm, weight 15–23 g) of the family Motacillidae, distinguished by its bright yellow underparts, olivegreen upperparts and prominent supercilium. The individuals recorded during this trail were wholly bright yellow below, with a greenish back. The head was blue-grey with white eyebrow (Figure 1). The recorded plumage indicates it to be a breeding male regionally from central and Southwest Europe. The species is polytypic, with several subspecies recognised across its broad Palearctic range1 . M. flava breeds across temperate Europe and Central Asia and migrates to sub-Saharan Africa and South Asia for the non-breeding season. In India, it is a regular winter migrant, typically arriving late September and departing by February or early March1 . Bar chart data from eBird corroborate this pattern, showing a marked decline in records from March onwards in Rajasthan2 . The IUCN Red List currently classifies the Western Yellow Wagtail as Least Concern, but recent assessments indicate declining populations in parts of its range , attributed to habitat loss and agricultural intensification. Alongside this observation, Siberian Stonechat (Saxicola maurus) and Eurasian Wryneck (Jynx torquilla), both winter migrants to the Indian subcontinent, were also recorded at the same site in late April 2025

Subject: Why is ‘North-East’ a natural laboratory of geodiversity in India?
Keywords: Brahmaputra plain, Eastern Himalaya, geodiversity, Meghalaya Plateau, North-East India.
Abstract: The north-eastern part of India, consisting of seven states, namely Arunachal Pradesh, Assam, Meghalaya, Manipur, Mizoram, Nagaland and Tripura, can serve as a natural laboratory of geodiversity in India. This living laboratory can offer important insights into the geotectonic evolution of South and South-East Asia, the quaternary fluvial dynamics, the richest karst topography, the Meghalayan age, the site associated with one of the best preserved and most complete records of K–Pg boundary transitions worldwide, and the nexus among geodiversity, biodiversity and human health and wellbeing. Therefore, the concerned region requires a comprehensive geotourism policy that will not only promote its unique geological diversity but also help to conserve all kinds of geological, ecological and even cultural treasures that the region has since time immemorial.

Subject: India’s pioneering high-altitude atmospheric and climate research in the Himalayas
Keywords: None
Abstract: India is constantly upgrading its meteorological infrastructure and capabilities for making high-precision weather predictions and climate projections on regional and global scales. Advanced climate models powered by supercomputing facilities and large-scale observational data have significantly improved India’s capabilities to forecast weather and climate events, including extreme weather events such as tropical cyclones and tsunamis, on different spatio-temporal scales. However, the predictive capabilities of climate models remain restrained due to the lack of adequate observational atmospheric data from high-altitude regions1 , especially the Himalayas – the ‘Third Pole’ of the Earth2 . Such underrepresentation of the Himalayas limits our understanding of the global weather and climate processes.

Title: Survival concerns in endemic trees of India

Subject: Survival concerns in endemic trees of India
Keywords: None
Abstract: Trees are distinctive from other life forms of plants as they characterise the landscape they prevail in and live for decades with minimal attention. They are well-adapted and resilient to their situations and provide ecological, economic, cultural, and aesthetic payoffs to many beneficiaries. About 22,214 species represent the country’s entire wealth of flowering plants as per the records of the Botanical Survey of India (BSI) (Plant Discoveries, 2024). Trees constitute 3460 species, including 1262 introduced species, and 27% of them are exclusively confined to the Indian flora and are recognised as Indian endemic species (Pusalker et al., Trees of India, Vol. 1, 2025). These are restricted species; occasionally, the range is symbolised by a single population (point endemics), thereby susceptible to extinction. Their elimination here amounts to their global elimination. Our concerns naturally go with them in the prioritisation of species conservation. India, which is committed to biodiversity conservation and is a signatory to multiple conservation treaties, has a greater obligation to protect them. The IUCN Red List (1964) uses five criteria: the species’ population decline or increase/geographic range/small population size decline/very small or restricted population/quantitative analysis to assess the threat of species extinction. The guidelines for applying the IUCN Red List Categories and Criteria are accessible with Version 16, March 2024, which are being adopted by many countries to prioritise species for conservation. This red list categorisation assesses information about range, population size, habitat and ecology, use and/or trade, threats, and conservation actions taken, if any. The said information on the species concerned is to be collected through extensive and intensive field explorations in their probable areas of presence. It expedites necessary conservation decisions. The species’ status can be updated and revised as one acquires more quality data from field work.
