Subject: Maintaining agricultural sustainability through carbon footprint management
Keywords: Agricultural management, carbon footprint, climate change, greenhouse gas emissions, soil health.
Abstract: Global awareness of climate change issues, particularly changes in air temperature, has increased dramatically over the last half a century. Concerns regarding ecosystem sustainability and human existence on Earth arise due to population expansion, rising surface temperatures and increased greenhouse gas (GHG) emissions. Agriculture accounts for approximately 18% of the total GHG emissions, largely in the form of carbon dioxide, methane and nitrous oxide. As a result, limiting GHG emissions is critical to alleviating the consequences of climate change, which is attainable if the concept of carbon footprint is understood. Cereal production produces more GHG emissions than other farming methods, including vegetables and fruits. ‘Carbon footprint’ is a popular term in agriculture and environmental research due to its involvement in environmental impact assessments and global climate change. GHG emissions are influenced by changes in land use, soil type and agricultural management approaches. Therefore, it is important to consider how agricultural management practices, particularly those involving the soil and related systems, affect the relationships between photosynthesis and GHG emissions. This study deals with the concept of carbon footprint in agriculture and various mitigation measures for its management

Abstract: Indian pangolins or thick-tailed pangolins, Manis crassicaudata (the word crassicaudata derived from Latin words crassus (thick or heavy) and cauda (tail)), are medium-sized mammals weighing between and 18 kg. They primarily feed on termites and ants, and their specialized feeding habit, known as myrmecophagy, has led to specific morphological adaptations such as a long sticky tongue and long sharp claws1 . The keratinized scales of pangolins act as an armour, protecting them when they curl up into a ball (referred to as ‘pengguling’, a Malay word meaning ‘rolling up’) in response to threats . Ironically, these scales, which evolved to protect pangolins against predators, now drive them to extinction as thousands of pangolins are killed for their scales every year by humans . Indian pangolins face extreme risk of extinction due to poaching, habitat loss and fragmentation . Their habitat extends from northern Burma and the southern Yunnan Province in China to the eastern parts of Punjab and Sindh in Pakistan, as well as most of India, Nepal, and Bangladesh5 . Despite the wide range of pangolins, little is known about their distribution and status, except for a few presence records obtained from the semiarid regions of western India , moist deciduous forests of North Bengal , tropical moist forests of the Western Ghats10 and the lower Shivalik hills of Himachal Pradesh

Subject: Learning botany in the field: can we afford to give it a miss?
Keywords: Learning botany in the field
Abstract: The throbbing and rich discipline that Botany is today is due to its founders who travelled across the Earth studying plants growing in different parts and geographical niches of the world. Equipped with a keen sense of observation, they helped develop the discipline of field botany that records the habit and habitat of a plant and assists in the taxonomic identification of plants, including those that appear similar but, in reality, are different. Field study is an essential and integral part of learning about living organisms, including plants, animals and the teeming microbes that outnumber all plants and animals taken together. Learning biology in field settings is a real-time experience which helps develop creativity, environmental awareness and a sense of accountability towards nature among students. Observations on the natural habitats, plant habits, ecology, growth cycle and biology provide deep insights regarding plants that are important sources of food, fuelwood, timber and medicine. Since neither the environment nor the diverse living organisms inhabiting a constantly changing interconnected world remain the same, field botany is never static and requires monitoring by the days, weeks, months and years.

Abstract: No experimental study has been done so far on the natural degradation of the traditional Sanchi manuscripts made from the bark of agarwood (aloeswood, i.e. Acquilaria agallocha Roxb., locally known as Sanchi tree in Assam, North East India). In this study, SEM, FTIR, XRD and stress–strain test using UTM were carried out on lignocellulosic Sanchi manuscripts to determine cellulosic variations. Reduction of crystallinity index of cellulose, decrease in tensile strength and toughness indicated the natural degradation of Sanchi manuscript. The study reveals that the Sanchi manuscripts are highly vulnerable to natural degradation, and therefore need scientific techniques and treatments to prolong lignocellulosic changes.

Subject: Circulation of A2 subclade of Avipoxvirus in pigeons of the Andaman and Nicobar Islands, India
Keywords: Avipoxvirus, chicken, clade and subclade, fowlpox virus, pigeon.
Abstract: Genus Avipoxvirus, an important member of the family Poxviridae, has 12 species which have been recognized by the International Committee on Taxonomy of Viruses (ICTV). Fowlpox virus and pigeonpox virus are two important species that may affect other species of birds, besides chicken and fowl. Hence, accurately identifying species, clades and subclades of Avipoxvirus is vital to design and implement adequate control strategies. The present study was carried out in a pigeon colony showing symptoms of pox. A fragment of viral Pan-genus 4b (P4b) gene was amplified and sequenced. As an equivocal and prototype species, sequence information of fowlpox virus isolated from an infected bird was also generated. The generated sequence information was compared with those of previously reported strains. It was found that both fowlpox and pigeonpox viruses belonged to clade A, and there was circulation of A1 and A2 subclades in chicken and pigeon respectively. From India, one report showed the circulation of A1 and A3 subclades in Indian chickens and pigeons respectively, since the other reports were based on clinical symptoms, histopathological examination and comparison of sequence information with those available without distinct demarcation of clade and subclade of Avipoxvirus. This study describes the findings of the novel A2 subclade of Avipoxvirus and the existence of pigeonpox in the Andaman and Nicobar Islands, India.

Subject: Utilizing machine learning algorithm, cloud computing platform and remote sensing satellite data for impact assessment of flood on agriculture land
Keywords: Agriculture, cloud computing platforms, floods, machine learning algorithm, remote sensing data.
Abstract: Floods are one of the most devastating natural disasters that cause immense damage to life, property and agriculture worldwide. Recurring floods in Bihar (a state in eastern India) during the monsoon season impact the agro-based economy, destroying crops and making it difficult for farmers to prepare for the next season. To mitigate the impact of floods on the agricultural sector, there is a need for early warning systems. Nowadays, remote sensing technology is used extensively for monitoring and managing flood events, which is also used in the present study. The random forest (RF) machine learning (ML) algorithm has also been used for land-use classification, and its output is used as an input for flood impact assessment. Here, we have analysed the flood extents and their impact on agriculture using Sentinel-1 SAR, Sentinel-2 and Planet Scope optical imageries on the Google Earth Engine (GEE) cloud computing platform. The present study shows that floods severely impacted a large part of Bihar during the monsoon seasons of 2020 and 2021. About 701,967 ha of land (614,706 ha agricultural land) in 2020 and 955,897 ha (851,663 ha agricultural land) in 2021 were severely flooded. An inundation maps and area statistics have been generated to visualise the results, which can help the government authorities prioritize relief and rescue operations.

Abstract: To ascertain the impacts of flood-affected and landslide impacted soils on the microbial community and soil nutrient status, an assessment between disturbed and undisturbed soils was conducted. Without discernible differences between soils impacted by flooding and landslides, the total bacterial and fungal population had decreased in disturbed soils. The lack of organic carbon and copper in flood-affected soils profoundly impacted the bacterial population. The disturbed soils were found to have reduced organic carbon, nitrogen and micronutrients. The microbial isolates that persisted even in these degraded conditions may be considered potential bioagents for the restoration of disturbed soils

Subject: Difference in synonymous polymorphism related to codon degeneracy between co-transcribed genes in the genome of Escherichia coli
Keywords: Base substitution, codon degeneracy, co-transcribed genes, replication and transcription, synonymous polymorphism
Abstract: In our study, we compared synonymous polymorphism in co-transcribed gene pairs within five well-known Escherichia coli operons (rpoB/C, lacZ/Y, kdpA/B, araB/A and bcsA/B). Interestingly, the transition to transversion ratio between gene pairs were different due to their compositional differences of two-fold and four-fold degenerate codons. The differences in polymorphism spectra were more pronounced in four-fold and six-fold codons compared to two-fold degenerate codons. Notably, rpoB and rpoC showed significant distinctions in UCC, GUA, CCG, GCU, GGC and CGC codons. Similar trends were observed in other gene pairs, particularly in higher degenerate codons. Notably, two-fold degenerate codons primarily exhibited synonymous polymorphisms through transitions, while higher degenerate codons encompassed both transition and transversion events. This underscores the intriguing role of degenerate codons in molecular evolution.

Keywords: Cucumber, foraging activity, pollination efficiency, stingless bee, yield.
Abstract: The present study deals with the foraging activities and pollination efficiency of Tetragonula iridipennis in cucumber (Cucumis sativus) under protected conditions. Experiments were conducted during two seasons (summer and winter) with three different treatments: open pollination (OP), pollinator exclusion (PE) and stingless bee pollination (SBP) in Assam, North East India. The foraging activity of T. iridipennis was checked in SBP treatment at different timings after installing a 15,504 cm3 beehive. The pollination efficiency of T. iridipennis was also examined among the three selected treatments. The peak period of visitation on cucumber flowers was recorded during 0800-0900 h of the day during both seasons. The yield increase of SBP over PE during both seasons was five times higher. These findings indicate the significance of T. iridipennis as an effective pollinator in greenhouse cucumbers.

Keywords: Art restoration, binders, mural paintings, pigments.
Abstract: Eight micro-samples from mural paintings of Malayadipatti and Adiyamankottai temples in Tamil Nadu, India were studied using binocular microscopy, thin film crystal X-ray diffraction, X-ray fluorescence, Fourier transform infrared spectroscopy, micro-Raman spectroscopy and field emission scanning electron microscopy to understand the original constituent materials of the pigments, binders and the methods of painting. Red paint had a mixture of cinnabar and hematite. The yellow colour resulted from orpiment. Orange hues were produced a mixture of orpiment and hematite. Grey colour was produced by a mixture of calcium carbonate and manganese dioxide. Black tones were prepared primarily using lamp black. The minerals used in both the temples were nearly identical. The appearance of proteinaceous materials/oils as a binding medium in all samples indicated the use of a tempera wall painting technique. These findings help improve our understanding of the methods and materials used in mural arts and serve as a guide for their future restoration.

Subject: Does socio-economic dynamics influence crop yield variability?
Keywords: Agricultural technologies, crop production, farmers, policies and subsidies, socio-economic factors
Abstract: The present study examines the current research on how socio-economic factors affect the decision-making process and adoption of agricultural technologies by farmers in crop production scheduling. It reviews existing literature to identify gaps in knowledge and determine the most relevant factors influencing crop production in Northwest India from 2016 to 2021. The study finds that socio-economic factors, such as education, age, awareness and financial limitations, significantly impact farmers’ decision-making when it comes to crop planning. Additionally, societal issues like politics and religion also influence crop output. The study suggests that government policies and subsidies can help improve farmers’ livelihoods, and effective communication from agricultural scientists can encourage the adoption of affordable and environmentally friendly production technologies. However, the study emphasizes the need for more primary data to address socio-economic constraints in intervention efforts.

Reference: The rhizosphere–plant–microbial association is a complex and intricate system susceptible to various organic pollutants, including polycyclic aromatic hydrocarbons (PAH). Since the soil acts as a sink of PAH, their accumulation shifts the delicate rhizosphere–plant–microbe equilibrium and enters the food chain through plants. How the presence of PAH in the rhizosphere affects the rhizosphere–plant–microbial system is still unclear. This study aims to understand the effects of PAH on rhizosphere–plant–microbial interactions. It also explores the potential use of microbes to alleviate PAH-induced stress in the soil for effective and sustainable management.

Subject: National Initiative on Undergraduate Science programme in chemistry
Keywords: Chemistry, national initiative, nurture programmes, student camps, teacher workshops, undergraduate science education.
Abstract: The article discusses the National Initiative on Undergraduate Science (NIUS) programme in chemistry conducted by the Homi Bhabha Centre for Science Education (TIFR), Mumbai, which was initiated in 2004. Being located in a science education research and development institution, the programme has made efforts to interact with chemistry teachers and first-year undergraduate students and, thus, is different when compared to similar programmes within the country. The article reviews the key ideas of the programme, its growth and evolution to date and likely directions for its expansion in the near future.

Subject: Defining the ‘urban critical zone’ for global sustainable development
Keywords: Ecosystem services, natural environments, planetary boundary layer, sustainable development, urban critical zone
Abstract: With urbanization, cities are becoming new landscapes, significantly altering the properties, processes and pathways of previous natural environments. The natural critical zones that have existed for millennia are rapidly getting modified by the superimposition of the urban components to give rise to a new critical zone system, viz. the urban critical zone. The clogging and bypassing of the natural process pathways and the increasing demands of urban populations for ecosystem services put the native critical zone and the adjoining zones under stress. To elucidate this point, we present a case study on Delhi, the capital city of India, to demonstrate how the urban critical zone is unsustainable. We exemplify the increasing demand and supply gap of basic ecosystem services, such as clean air and water, that are essential to sustain life. In doing so, we redefine the limits of the critical zone in urban areas, recognizing that significant parts of cities are beyond the presently defined critical zone.

Subject: Need to declare the Higher Himalaya an eco-sensitive zone
Keywords: Need to declare, Higher Himalaya, eco-sensitive zone
Abstract: The recent disasters in Uttarakhand, India (e.g. 2013 Kedarnath, 2021 Rishi Ganga and 2023 Joshimath) and Himachal Pradesh (e.g. 2000 and 2013 Satluj–Kinnaur floods and 2023 Beas floods) have reignited the debate of anthropogenic impact on Higher Himalayan valleys and potentially increased impact of disasters in the region1 . It is feared that under the impending climate change scenario, the sustainability of the geologically fragile Higher Himalayan ecosystem would be threatened, endangering the safety of infrastructure such as habitation sites, roads and hydropower projects. The climate sensitive Higher Himalaya is not only the abode of endemic and endangered flora and fauna but also contains a large number of glaciers which sustain millions of people inhabiting the Indo-Gangetic Plains. Therefore, it is now being increasingly considered that similar to the Bhagirathi Eco-Sensitive Zone, the river stretches between the headwaters till the southern flank of the Main Central Thrust (MCT) covering a stretch of ~125 km should be declared as eco-sensitive zones
