Keywords: Aphid predation, Carinostigmus costatus, Hyadaphis coriandri, nesting activity.
Abstract: The predation of aphid hunting wasp, Carinostigmus sp. on fennel aphid, Hyadaphis coriandri is reported from India. The solitary wasp was molecularly identified as Carinostigmus costatus (NCBI Accession No. OQ913733.1). The wasp constructed its nest in the pithy stems of Ceasalpinia pulcherrima (peacock flower) provisioning fennel aphid, H. coriandri. There was a decrease in the population of the fennel aphid, H. coriandri with an increase in the nesting activity of the solitary wasp, C. costatus. Our study indicated that the solitary wasp, C. costatus could be easily conserved by providing pithy stems of C. pulcherrima as nesting habitats around the field borders for natural regulation of aphid infesting fennel.

Subject: The Beas river floods 2023: a watershed moment for paradigm shift towards urbanization and development in the Higher Himalayan valleys
Keywords: Alluvial deposits, anthropogenic intervention, Beas river flood, higher Himalaya, Indian Summer Monsoon.
Abstract: The present study is done in the Beas river (Manali to Mandi town) after the July 2023 flood to assess the geomorphic and geological vulnerability of the terrain and understand the role of human intervention in the disaster. The study is based on preliminary field observations and morphometric analysis that indicates that the surfaces proximal to the trunk riverbed and the ephemeral tributary channels suffered maximum damage. Along the upper Beas river, the lateral erosion caused by hyperconcentrated flows saturated with paraglacial sediments partly obstructed the river and also increased the erosivity that also led to remobilization of midchannel bars along with the uprooted trees. In the downstream (southern mountain front), maximum damage was caused by activating seemingly dormant ephemeral tributary channels. The slope-channel coupling locally bulked the sediment supply of the trunk river. The disaster was force amplified when the river was temporarily obstructed by the manmade structures (e.g., suspension bridges), and most importantly, urban settlements (largely hotels) on the flood plain. Also, many public buildings suffered as these were constructed in/along the ephemeral tributary channels, which were temporarily blocked by these structures, as well as by logged tree trunks. The Beas flood is yet another brutal reminder to change our perception towards the developmental approach, given that extreme events are projected to increase in the Himalaya.

Keywords: Agricultural extension, group decisionmaking, self-help groups, swarm-intellig
Abstract: The concept and utility of self-help groups (SHGs) are proven facts, and they have significantly contributed to group-led extension activities on a large scale. These SHGs play an instrumental role in empowering their members and in many core aspects of farming. Still, these groups also face various challenges, among which ineffective group decision-making is prominent. Therefore, it is critical to strengthen the SHGs by resolving the issues of stability for strengthening the extension system in light of agriculture and rural development at the national level. Swarm intelligence is a phenomenon through which the swarm of honeybees perform various group tasks and takes crucial group decisions effectively and efficiently, utilizing their collective intelligence. Therefore, the study was intended to map the group decision processes among honeybee swarms and their inbuilt influences to relate them to the decision-making processes among SHGs. The present study inferred that seven key factors, i.e. decision impulse, conviction of the decision, engagement in decision, decision duration, decision alignment, extent of participation and real time physical negotiation, contributed to the effectiveness of swarm-intelligence-based group decision-making.

Abstract: The present study reports the well-preserved Ediacaran sack-like soft-bodied fossils assigned as Finkoella ukrainica and Finkoella oblonga from the Sonia Formation of the Jodhpur Group, Marwar Supergroup, western Rajasthan, India. The F. ukrainica is found in elliptical, ovate-shaped and sometimes oblong or cucumber-shaped forms with a distinct short neck, and a small circular protrusion or depression may be present on the organism. F. oblonga is elongated, ovate to cucumber-shaped fossil specimen with poorly preserved six longitudinal low grooves and ridges arranged parallel to the marginal ridges of the organism. Both F. ukrainica and F. oblonga are also well comparable to the type materials of Ukraine in the preservation of concave (negative relief) and convex (positive relief) with oral/atrial siphons, double marginal ridges/grooves and elevated edges in the Sonia Formation. The Finkoella fossil remains are believed to be the flattened bodies of tunicate organisms. Similar sack-shaped Burykhia fossils recorded in the White Sea of Russia contrasted to sponges and similar hollow-shaped organisms have been interpreted and compared with lichenized fungi and fungal affinity. Thus, the biological affinity of the Finkoella organism is still unresolved.

Abstract: In the present article, a methodology has been discussed to evaluate the influence of activity concentration of soil samples containing heavy metals in the environment. The approach leverages a simulated germanium detector and a cylindrical geometry sample configuration to analyse soil samples with varying densities. The results showed a positive correlation between the soil densities and activity concentration, with an average correlation coefficient of 0.99 indicating that variations in density affect the activity concentration measurements. To mitigate this error, a demonstration of the self-absorption correction as a function of density, being an essential part of the present study has been included.

Keywords: Catchment area, Central Water Commission, Ganga, hydrology, remote sensing
Abstract: Geospatial information on river gauging stations, such as station locations, catchment boundaries, river flow paths and other hydrographic data are basic building blocks of hydrological analyses. Such information for India’s river basins is available from Central Water Commission (CWC) and water resources information system (WRIS), but is limited in extent and unreliable. Using widely used global hydrography products, catchment boundaries were delineated for 100 gauging stations in the Ganga river basin (GRB), and their catchment areas were estimated. The delineated boundary for the GRB, and also station-wise catchment areas from the present study were much more consistent with global hydrography products than those available from CWC and WRIS. Lack of reliable, analysis ready hydrography data is a hindrance to hydro-climatological research. The long-term objective of this study is to help build such a needed dataset using high-resolution remote sensing products.

Abstract: Estimates by the Central Water Commission (CWC) on flood damage to crops, houses and public utilities from 1953 to 2020 is about Rs 4 lakh crores (INR 4 trillion)1 . Therefore, a comprehensive flood forecasting and early warning framework for India is essential to mitigate the above damage. The main input for flood forecasting is the availability of dependable rainfall forecasts. Despite the stochastic nature of rainfall forecasts, the methodologies adopted in India for flood forecasting are mostly deterministic in nature. Hence, there is a need to translate the ensemble rainfall forecast into an ensemble hydrologic prediction by integrating meteorologic forecast, hydrologic and hydraulic models . With the advancement of science, reliable rainfall forecasts are made possible with sufficient lead time from many weather forecasting models.

Subject: Assessment of agricultural land area lost due to Brahmaputra riverbank line erosion in Assam
Keywords: None
Abstract: The River Brahmaputra is characterized by its exceedingly large flow, enormous volume of sediment load, continuous changes in channel morphology, rapid bed aggradations, bank line recession and erosion. Heavy rainfall, associated with severe flooding, excessive siltation and migration of river channels, causes erosion on both sides of the Brahmaputra river. The river has a braided channel in most of its course in the alluvial plains of Assam, and the river flows through 21 districts of the state. The braided nature, lateral changes in channels and continuous migration of rivers cause severe erosion along the banks, leading to a considerable loss of good fertile land each year. Shear failure due to undercutting upper bank materials during high flooding and over-steepening of bank materials also leads to bank failures in both the banks1–3 . Damages caused by erosion run into several hundred crores every year. Bank erosion by the rivers has been a serious issue for the last six decades as more than 4.27 lakh hectares (ha) of land have already been eroded by the River Brahmaputra and its tributaries since 1950, which is 7.40% of the area of the state. As assessed, the annual average loss of land is nearly 8000 ha. The width of the River Brahmaputra has increased to 15.00 km in some places due to bank erosion (https:// waterresources.assam.gov.in/portlets/flooderosion-problems).

Abstract: The performance of the global economy is supposed to be ruled by the economies of each country1 . With this, the economic instability that countries experience during global crises creeps in, as evident from the Global Economic Outlook Report 2020, which emphasized how the COVID-19 pandemic affected the global economy2 . However, when it comes to the space economy, countries seem to show resilient support for multiple reasons, as evidenced by research from Morgan Stanley, which expects the global space industry to grow into a US$ 1.1 trillion market by 2040, from about US$ 350 billion in 2016 (ref. 3). One of the reasons is that the various space stakeholders use a sustainable approach to space research. For example, in scenarios where stakeholders from one country specialize in cost-effective satellite launches, support other countries to launch their satellites into orbit, thereby reducing resource wastage and effective utilization of financial resources. Other reasons include investor sentiments, which lead to volatility in the stock market (changes in support and resistance), thus affecting the returns4 . Such an effect was not seen in the space industry, as the effect of support and resistance on the overall share market did not affect the space companies due to most of them not being listed in popular stock exchanges, for example, SpaceX and Skyroot Aerospace Private Limited5 . This resulted in an ultimate decline in costs for space-based ventures, resulting in the realization of the very celebrated aspiration of ‘SPACE FOR ALL’, as obvious from making spacesuits for women3 , which earlier were not a priority

Subject: Hundred years of research on Drosophila ananassae has revealed a number of unusual features of this species
Keywords: None
Abstract: Drosophila ananassae was originally described by Doleschall in 1858 from Ambon Island in Indonesia. This species came into notice when Morgan, Bridges and Sturtevant compiled data in a volume entitled ‘The Genetics of Drosophila’ in 1925 as D. caribbea Sturtevant in the chapter ‘other species of Drosophila’. Kikkawa in 1935 verified D. caribbea as D. ananassae. The first mutation in this species was curved wing, an autosomal recessive gene on II chromosome reported by Sturtevant in 1921. Since then D. ananassae has been utilized extensively for different kinds of studies and results of these studies conducted during the last hundred years have clearly revealed that D. ananassae is genetically unique species and stands distinct from other species of the genus Drosophila. The important unusual features of this species are: spontaneous meiotic male recombination, presence of chiasmata in males, high mutability, optic morphology hyper mutability system, absence of genetic coadaptation, Y-4 linkage of nucleolus organizer, high frequency of pericentric inversions and translocations, population substructing, parthenogenesis, extra chromosomal inheritance, incipient sexual isolation, inversion karyotypes and mate recognition system, spontaneous genetic mosaic, segregation distortion, lack of correlation between crossing-over and chromosome distance between inversions, rare male mating advantage, trait and sex specific fluctuating asymmetry, female and male remating and sperm displacement, speciation in south Pacific populations, association with a bacterium Wolbachia, variation in resistance to environmental stress, nutrition regulated stress resistance, correlation between inversion karyotypes and mating propensity and phylogenetic relationship with its sibling D. pallidosa which is in statu nascendi

Abstract: The United Nations Climate Change Conference COP 28 was held and concluded in Dubai. It is particularly important as the first ‘global stocktake’, a process for countries and stakeholders to examine the progress towards meeting the goals of the Paris Agreement. The conference outcome was a revelation of the slow progress in most areas of climate action. Consequently, nations collectively made a pronouncement on the way forward to accelerate climate action. As usual, transitioning from fossil fuels to renewable energy sources was one of the focus areas.
