Keywords: Space based observations, annular solar eclipse, June 2020
Abstract: On 21 June 2020, an annular solar eclipse phenomenon took place. The path of the ‘ring of fire’ spanned across Africa and Asia. In addition to the traditional methods of observing the solar eclipse through telescope using solar filters or sing solar projectors, this phenomenon can also be captured using satellite data. The shadow cast by the moon on the surface of the Earth leads to a drop in the solar flux over the Earth’s surface, which can be recorded by space-based sensors in the visible-near-infrared spectral range. We have presented the natural colour composite images eclipse conditions from three different satellite sensors, i.e., Moderate resolution Imaging Spectroradiometer (MODIS) over Terra/Aqua (https://modis.gsfc.nasa.gov/)and Visible Infrared Imaging Radiometer Suite (VIIRS) over NOAA-20 (https://data.nodc.noaa.gov/).

Abstract: Some of the non-native invasive species of plants invade various habitats, thereby posing considerable threats to sustenance of native flora. These may be deliberately introduced for cultivation, but they become widespread and naturalized in due course of time. Once, established, such weeds are not easy to control. During a recent floristic survey in Srinagar Garhwal, Uttarakhand, India (altitude 595m amsl, 30°13’11.64” N, 78°47`36.), the present authors came across an herb with shining white flowers. It was found in a shady place, adjacent to the road, farming dense patches in few localities nearby.

Abstract: Tunicates are known to exhibit fast growth rate by consuming phytoplankton during their unusual blooming period. Hence their position in the food web is vital for the environment. During our regular faunal exploration under the ‘Fauna of Lakshadweep: Echinoderms’ survey on 5 February 2018, we have noticed a pryrosome swarm at the subtidal environment of Bangaram Island of Lakshadweep Archipelago. It was identified as the giant pyrosome, Pyrostremma spinosum (Herdman, 1888), which is found as groups of colonial organisms with thousands of Individual zooids, drifted in the sub-tidal regions at depths between 8 and 15 m.

Abstract: The extent of original medical research in India remains sub-optimal despite competence and facilities. One of the factors could ignorance about, and a general lack of rational appreciation of India’s traditional knowledge systems (TKS), which could otherwise be a good source of new ideas, and thus innovation. The existing silos do not allow sufficient cross-disciplinary dialogue between the mainstream biomedical community and those in the KTS to promote active and unbiased research in TKS. The new science, Technology and Innovation Policy (STIP) proposed by the Department of Science and Technology (DST2020), Government of India has the potential to accelerate the confluence of ancient and contemporary wisdoms, if appropriately articulated, inter-digitated and executed.

Subject: Syncing phenology phase and canopy spectral reflectance of common tree species of four forest covers in India
Keywords: Absorption band, canopy-level spectra, forest cover, phenology phase, rainfall gradient, tree species
Abstract: Variability in the leaf phenology of tropical trees impacts their growth. How phenology of tree species responds over rainfall gradient is relevant to study in the light of current climatic changes. Airborne visible and infrared imaging spectrometer-next generation (AVIRIS-NG) spectral datasets have been considered for this study as they not only provide wider area of coverage, but also high spatial and spectrally resolved output. Canopy-level spectra of 16 common species of four different forest covers in India were synced with observed phenology phase and the annual rainfall in each forest cover was recorded. Reflectance spectra of the same species in the four forest covers distinctively differed over rainfall gradient, indicating intra-species pliability. Consistent lower reflectance/higher absorption at chlorophyll bands of all the common deciduous species in the higher annual rainfall region over that with relatively lower rainfall indicated that deciduous species acclimate green foliage phase of the phenology cycle. Boxplots of reflectance values of chlorophyll absorption band of 16 species showed a decrease in the variability of the datasets over the four forest covers, revealing that increasing rainfall provides better synchrony in the phenology phase of the observed tree species. The study highlights the importance of AVIRIS-NG spectral datasets in monitoring different phases of forest phenology associated with growth potential dynamics effectively under changing rainfall pattern.

Abstract: Study of ecomorphological variations in fish of different habitats helps in understanding the diversification of body traits developed due to different environmental conditions. The morphological variations in sub-populations of Trichogaster fasciata induced by different habitats characterized by different environmental conditions have been studied. Overall, 86% and 92% of individuals were correctly classified using linear discriminant function analysis of truss and geometric morphometrics. The individuals from lotic habitat showed a more streamlined body, sloping head and inflated caudal peduncle than those of the lentic habitat which displayed deeper body, broader head and deflated caudal peduncle. Relative warps were used to quantify variations in the form of characteristic interpretation of body shape. The results from the present study help clarify the questions of morphological predictions in the sub-populations of this fish across different flow habitats and provide insights into phenotypic variations in the T.fasciata population.

Keywords: Ancient monument, chemical and mineralogical analysis, coastal sites, lime plaster, salt intrusion
Abstract: The present study aimed to unravel important features regarding the ancient lime plaster for a Portuguese monument in the Indian Ocean coast for the formulation of compatible repairing materials and to determine its condition to plan conservation works. The study illustrates the hydraulic properties of lime used for the construction, the extent of salt intrusion into the plasters, area of intrusion and its source. Wet chemistry results reveal that the dampness and capillary actions led to salt diffusion into the walls and its percolation to different heights of the monument. Due to the intrusion of water into the matrix of the plaster , its inner core becomes less cohesive, resulting in brittleness of lime combination and peeling-off of the upper fabric. Thermal techniques, X-ray diffraction and X-ray fluorescence results identified the mineralogical composition of the construction materials, viz. Lime plaster and mortar. Further, they confirmed the uniqueness of lime combination used to build the monument with lime-silica ratio in the range 1: 1 to 4: 1 and its transformations over a period of time in saline atmosphere. This study provides an overview regarding the ancient lime plaster used in the monument and may help to devise new compatible materials for subsequent conservation works.

Abstract: During a survey of psychrotrophic soil fungi from a high-altitude cold desert (4000 masl), nine species of the genus Aspergillus were discovered. One of the species was identified as Aspergillus aeneus based on its morphological and molecular characterization. This species has been rediscovered from India from an extreme habitat as a psychrotolerant after 56 years of its first report from topical soil in Madhya Pradesh. Globally, this fungus is a rare species with limited occurrence, being reported so far only from India, Somalia and Costa Rica. It is a novel representative of desert fungi that showed cellulose and protease activity but lack lipase activity.

Abstract: Oilseeds can be used to manipulate ruminal fermentation for attaining cleaner and better production. The effect of feed-grade niger seeds was studied on in vitro rumen fermentation parameters in comparison to sunflower seeds. Methane production decreased (P≤0.01) with incorporation of both seeds. In vitro digestibility of dry matter and organic matter reduced at higher incorporation levels (above 5 %, DM basis). Fermentation pattern of niger and sunflower seed-based total mixed rations was highly comparable. The relatively higher anti-methanogenic potential of niger seeds could make it a better choice for alleviation of enteric methane and formulation of environment-friendly rations.

Abstract: In the first few months of its deadly spread across the world, COVID-19 mortality has exhibited a wide range of variability across different nations. In order to explain this phenomenon empirically, we have taken into consideration all publicly available data for 106 countries on parameters like demography, prevalence of communicable an non-communicable diseases, BCG vaccination status, sanitation parameters, etc. We used multivariate linear regression models and found that the incidence of communicable diseases correlated negatively. Demography, improved hygiene and higher incidence of autoimmune disorders correlated positively with COVID-9 mortality, and they were among the most plausible factors to explain COVID-19 mortality compared to GDP of the nations.

Subject: Role of electrostatics in artificial pollination and future agriculture
Keywords: Artificial pollination, crop production, electrostatic charging, food security, honeybee
Abstract: Pollination is the process of pollen detachment from the male part, i.e., anther of a flower, travel through a medium and deposition onto the female part, i.e., pistil of flower, thereby enabling fertilization and reproduction. Majority (87.5%) of flowering plants rely on animal pollination, on insects in particular with the remnants of species being wind-pollinated and with autonomous seed-producing capabilities. The reproductive phase of a plant has direct impact on crop yield and quality of produce in terms of bio morphological characters which affect its market value. On a global account, 80% of all plant species depend on pollination for reproduction, which influences 35% of crop production and worth US $117 billion per year. However, drastic decline in native pollinators has raised major concerns for the assurance of pollination services. Studies have revealed that the absence of pollinators may reduce the global agricultural crop production by 3-8%.Also, keeping in mind the world scenario of crop production and population expansion in relation to land under cultivation which remains the same; rather it shows a decreasing trend. Crop productivity has to be optimized from all possible points of view to meet the future food demand. Here the concept of precision agriculture arises, i.e. optimum utilization of available resources to achieve maximum possible yield from the same land area and desirable quality, without jeopardizing the environment. If the pollination process is disturbed due to climatic factors or insufficient pollinators during the period of bloom, it may directly result in lower yield, undesirable bio morphological changes and quality loss, leading to mass economic drop. To overcome this situation, artificial pollination techniques have been developed.

Subject: Challenges to identify and mentor gifted children in developing countries: the Indian experience
Keywords: Developing countries, gifted children, identification, mentoring, psychometric measurements
Abstract: The National Education Policy 2020 (NEP-2020) has recognized the need to identify, and nurture gifted and talented children beyond the school curriculum. Through systematic research, the National Institute of Advanced Studies, Bengaluru has developed multiple protocols for identifying and multi-level, multi-stage mentoring of gifted children. This study argues that there is need for a paradigm shift in the identification process that predominantly uses psychometric measurements in the portfolio that captures the actual data points of gifted children. This is particularly relevant for developing countries like India, which has a diverse population predominantly from disadvantaged communities. Establishing norms for standardized psychometric tests developed for the western populations will have inherent limitations to identifying the gifted children in multi-lingual and multi-cultural contexts. Needless to state, India has far too few trained psychologists to accomplish this task.
