Subject: Season-dependent reproductive performance in a non-seasonally breeding diurnal species, the zebra finch (Taeniopygia guttata)
Keywords: Clutch size, nest building, reproduction, seasons, zebra finch.
Abstract: The reproduction and its associated behaviour in a non-seasonal species are considered totally independent of seasons. To assess this, we examined seasonal differences in the nest building and reproductive performance in diurnal zebra finches that were hatched and raised in outdoor aviaries. Adult male and female birds were separately housed in cages equipped with two perches stacked in a large aviary, receiving the natural day length (NDL) and temperature conditions. Cages housing male birds were also fixed with a nest box. After two weeks of acclimation, the males and females were paired randomly, and the parameters of nest building and reproductive performance, such as the onset of egg laying, clutch size and hatchlings and fledglings per pair, were recorded in the winter (second week of November 2022 to the first week of February 2023), and subsequently similarly in the summer (third week of April 2023 to the first week of July 2023) seasons. The pairs took more time to initiate (mean ± SE – winter: 2.92 ± 0.58; summer: 2.33 ± 0.45) and complete (mean ± SE – winter: 6.75 ± 0.52; summer: 4.50 ± 0.27) the nest in winter, as compared to that in summer. Per pair, the clutch size was significantly smaller in winter (mean ± SE: 2.2 ± 0.36) than in summer (mean ± SE: 3.6 ± 0.34), but the hatchlings (P = 0.2123) and fledglings (P = 0.5302) were not significantly different between the two seasons, perhaps due to higher temperature and dryness in summer. These results indicated an underlying seasonality in zebra finches, which could be economically useful to those engaged in breeding and raising of pet species.

Subject: Martian/Lunar analogue research station in India: Ladakh as a potential site
Keywords: Analogue research, Ladakh, Lunar, Martian, terrestrial research station.
Abstract: India has a rich geographical landscape suitable for creating extra-terrestrial analogue habitats, which are crucial for supporting prolonged space missions and addressing the challenges of sustaining human life outside of Earth. It is also imperative that these habitats are analogous, both in design and proposed locations, as accurately as possible for meaningful lessons and research. India has set ambitious targets for its space program, which necessitates the construction of terrestrial research stations that can simulate extra-terrestrial conditions. We believe this is an opportune time to establish an analogue research station in Ladakh, that will benefit a diverse group of researchers. It can potentially become a shot in the arm for the Indian human space program. Apart from research, the tourism boost that such a site can give will also benefit local communities.

Subject: Relative abundance and diversity of insect foragers associated with inflorescence in dwarf varieties of coconut (Cocos nucifera L.)
Keywords: Conservation, diversity indices, ecosystem service providers, nut yield, pollinators.
Abstract: Ecosystem services offered by insect foragers in the coconut system are exceptional in utilizing pollen and nectar resources and, thereafter, rewarding effective pollination in coconut palms. The pollinator community recorded from dwarf varieties of coconut comprised 35 insect species, out of which 30 could be identified, belonging to 6 orders and 17 families. Insect fauna belonging to families Formicidae (ants), Apidae (bees) under Hymenoptera and Curculionidae (weevils) under Coleoptera were recorded in abundance from the coconut inflorescence. However, a considerable quantity of pollen grains clings onto the body parts of bees and assumes likely pollination services in coconut. Ants, though noticed in large numbers, may not be involved in pollination, probably because of their apterous nature and smooth body surfaces warranting in-depth scrutiny. Abundant floral visitors were registered during January–July compared to August–December. Higher nut yield in coconut recorded during January–May could be positively linked to enhanced foraging activities by insects, a classical instance of ecosystem services delivering economic benefits to farmers. The maximum insect activity was during the forenoon session, coinciding with anthesis time of coconut. Modulation among various diversity indices (Menhinick index, Shannon’s index) were recorded for species richness and temporal abundance for insect visitation in coconut. Conservation of these pollinators in the perennial coconut system is crucial for sustaining production and safeguarding the ecosystem. As coconut produces inflorescence around the year and ensures continuous pollen availability, coconut orchards can also be used for division of honeybee colonies during the brood rearing season.

Subject: Epigenetic DNA methylation markers: a non-invasive diagnostic approach for urinary bladder cancer
Keywords: DNA methylation, methylation-specific PCR, non-invasive biomarkers, urinary bladder cancer.
Abstract: Urinary bladder cancer (UBC) has high recurrence rates, making early detection vital. Promoter DNA methylation of CALCA, CCNA1 and P16 genes can serve as non-invasive biomarkers. The objective of the present study is to evaluate the promoter methylation status of CCNA1, CALCA and P16 genes in the blood of UBC patients compared to controls, and to explore their utility as non-invasive biomarkers. Blood samples from 169 participants, including 89 UBC patients and 80 controls, were analysed. Blood samples were collected, DNA was extracted for bisulphite conversion, followed by methylation-specific polymerase chain reaction (PCR). Statistical analyses determined the association between methylation status and clinical features. Methylation was detected in CCNA1 (66.2%), CALCA (53.9%), and P16 (72%) in UBC patients, significantly higher than in controls. Combined analysis of these three genes provided a sensitivity of 85% and specificity of 80% for UBC detection. Blood-based methylation of CCNA1, CALCA and P16 genes emerged as a promising non-invasive biomarker for early UBC detection. Further validation in larger cohorts is required.

Subject: Estimating geomagnetic field detection sensitivity of pigeons and passerine migrants using deep machine learning
Keywords: Deep learning, machine learning, magnetic field, navigation.
Abstract: The capability of homing pigeons and passerine migrants to derive navigation-rated information from the geomagnetic field (GMF), enabling them to navigate from unfamiliar sites, is a subject of research. Despite the vast trajectory information available from field experiments, the true accuracy of their map and compass sense are seldom reported. The recent developments in bird geo-tagging, precision world magnetic model and deep machine-learning capabilities enable us to understand the mechanisms underlying their innate abilities in true navigation. In this article, we machine-learnt the GMF anomaly in a 10 km2 region and analysed the flight path efficiency for a 10-km GMF-anomaly-guided trajectory using the developed deep-learning-based artificial intelligence (AI) algorithm. From the simulated flight path and comparing the computed efficiencies with the field-reported results, it is observed that the sensitivity of the GMF gradient detection sensory system in pigeons and passerine migrants in familiar and unfamiliar regions are in the range of 1–3 nT and 0.5–2.5 nT respectively. Identified results shall help implement AI based solutions for understanding spatiotemporal bird migration and enacting environmental conservation policies.

Subject: Effects of begomovirus infection on invasiveness of plant Croton bonplandianus Baill.
Keywords: Begomovirus infection, chilli leaf curl virus, Croton bonplandianus, exotic species, papaya leaf curl, pathogen reservoir.
Abstract: Invasive species are considered the second worst threat to biodiversity after habitat destruction, which was altered the function and service of the ecosystem. However, some exotic species fail to become invasive due to newly acquired enemies in the introduced range, as described by the ‘increased susceptibility’ hypothesis. In the present study, we have tested the increased susceptibility hypothesis: does begomovirus infection play an important role in the invasiveness of Croton bonplandianus in its introduced range. To understand the role of viral infection on the invasiveness of C. bonplandianus, the healthy and viral infected population density of C. bonplandianus was measured at different ecosystems by the quadrat method. Several first- and second-order branches, number of inflorescence per plant, number of buds/inflorescence, number of male and female flower/ inflorescence, number of seed/inflorescence, pollen and seed viability, chlorophyll content were measured in infected and healthy populations of C. bonplandianus. Results showed that the infected population of C. bonplandianus was higher in agroecosystems than in other ecosystems. The number and length of the inflorescences were maximum in healthy plants (24.74 ± 1.78 and 5.78 ± 0.13 respectively) than infected population (7.28 ± 0.88 and 2.04 ± 0.08 respectively). The number of male and female buds per inflorescences were also recorded maximum in healthy plants (21.19 ± 0.86 and 4.44 ± 0.13 respectively) and significantly different from the infected plants (9.99 ± 0.63 and 2.16 ± 0.12 respectively). Further, to identify the nature of the virus, viral DNA was isolated from the infected plant and confirmed through Rolling Circle Amplification followed by digestion to release the 2.7 kb and anticipated 1.3 kb. The above fragments were cloned, sequenced and analysed to identify the nature of the virus molecules. Surprisingly, 2.7 kb matched the papaya leaf curl virus, whereas 1.3 kb showed significant similarity with the alpha satellite, which is associated with the chilli leaf curl virus. Based on the results, we concluded that begomovirus infection has strongly affected reproductive traits of C. bonplandianus thus resulting in their failure to become an invasive species at the introduced range. However, the infected population of C. bonplandianus acts as a pathogen reservoir for various crop diseases, namely papaya and chilli leaf curl diseases.

Abstract: The present study investigates the effects of climatic variability on the reproductive development, flower sex ratios, and fruit set of Litchi chinensis cv. Dehradun in Himachal Pradesh from 2021 to 2023. Results reveal that cooler temperatures during floral bud induction (November–December) favoured balanced flower sex ratios and floral differentiation, promoting a successful fruit set. Higher temperatures in December 2022, however, led to increased vegetative growth and reduced reproductive output. Early flowering in January was advanced by cooler conditions in 2021–22, while improved rainfall and humidity further supported panicle health and fruit retention. Warmer April–May conditions contributed to elevated fruit drop and cracking, impacting yield. Additionally, cooler temperatures encouraged longer, more robust panicles, positively influencing flower production. These findings highlight the significance of cooler temperatures during key stages of litchi development and suggest the potential of adaptive practices, such as supplemental irrigation during dry spells, to counter climate impacts on yield and quality

Subject: Hydrology and water management in the Anthropocene: challenges and opportunities with particular reference to India
Keywords: Anthropocene, anthropogenic drivers, Indian rivers, tipping point, water resource management.
Abstract: The Anthropocene period is characterised by multiple stressors triggered by human-induced changes in the hydrological cycle and land surface transformations. The arrival of humans on this planet has significantly altered the biophysical systems, particularly since the Industrial Revolution, commonly known as the era of the Great Acceleration. It is important to recognise these changes in the hydrological systems and start planning country-specific and sustainable strategies to mitigate the challenges posed in terms of water availability and demands, water-related disasters, river health and river ecology. It is of particular importance to realise that our water resource system may already cross the tipping point of exploitation. Water is undoubtedly the most essential commodity for humans, but it is equally important to understand the needs of other ecosystems that depend on water. This article documents the challenges and opportunities of water resource management in the Anthropocene, which is particularly relevant to India and proposes a series of urgent measures to mitigate the situation. We reason that a better understanding of our hydrological systems will contribute to water security and resilience to society in terms of water and the environment and contribute to the growth of the nation.

Subject: Agrivoltaics – a potential solution for sustainable energy use from a global perspective
Keywords: Agrivoltaics, economic feasibility, global initiatives, integrated production, renewable energy, sustainable agriculture.
Abstract: Agrivoltaics, the amalgamation of solar panels with farming methods, has been steadily gaining traction as an innovative remedy for managing the conflicting needs of land in both food cultivation and energy generation. This concept emerged in the 1980s and has since gained momentum as a viable solution to optimise land usage for sustainable agriculture and renewable energy production. This integrated production model seeks to synergize food, energy and water resources, offering a sustainable alternative to traditional land division practices. The co-location of solar panels with crops demonstrates promising results, indicating increased agricultural outputs and energy yields. While global leaders like Japan, France, Germany and China have embraced agrivoltaics, challenges in regulatory frameworks and societal acceptance persist, particularly in European nations. Economic feasibility studies, conducted through simulations, highlight promising electrical and agricultural benefits. Comparative assessments against conventional photovoltaic systems reveal potential advantages, including increased electric yield and positive impacts on crop yields. Integration of agrivoltaics into diverse farming practices, from aquaculture to horticulture, offers a holistic approach to sustainable land use, promising secondary income and enhanced crop yields. By addressing farmers’ distress, agrivoltaics emerges as a unique solution, providing additional income sources and reducing reliance on traditional farming. As the world pivots towards sustainable agriculture, agrivoltaics presents a beacon of promise, poised to play a pivotal role in the world’s transition towards integrated and resilient agriculture.

Keywords: GDP baseline, intensity indicators, Lorenz curve, population baseline, science of science, size-dependent indicators
Abstract: We use an approach based on gross domestic product baselines and curated data from three ranking agencies to rate and benchmark Indian universities relative to their counterparts in other countries. Various scientific impact measures are used, considering both size-dependent and composite indicators. The relative position changes dramatically depending on the extent to which the intensity or quality of research is factored in.

Subject: India’s participation in the 6th BRICS meeting on research infrastructures and mega science projects
Keywords: None
Abstract: BRICS member states, in spite of their unique developmental strategies, need to address common concerns like better quality of life, inclusive economic growth, employment and a sustainable development pathway. Research and development (R&D) has emerged as a primary growth engine for driving scientific know- how, technological breakthroughs and innovative strategies towards facing these challenges. A collaborative BRICS effort utilizing its combined strength in science, technology and innovation (STI) can facilitate a platform for sustained growth for BRICS; an effective BRICS synergy can achieve what a single nation may find arduous, or take ages to achieve. Several past collaborative engagements have regularly demonstrated that BRICS has this potential.

Subject: National conference on urban biodiversity
Keywords: None
Abstract: Urban biodiversity refers to the wide variety of life forms, plants, animals, fungi and microorganisms that inhabit urban environments. However, the rapid expansion of cities in recent decades has led to significant habitat fragmentation, pollution, climate change and the loss of natural areas, all of which threaten the survival of many species. Urbanisation has become a major driver of ecological and biodiversity loss globally, as unchecked city growth contributes to land degradation, increased resource consumption, higher greenhouse gas emissions, and greater waste generation. Predictions indicate that by 2050, 70% of the global population will live in urban areas, intensifying the pressure on urban biodiversity and exacerbating these negative impacts.
