  • Nutraceutical potential of essential oils in dairy animal diets:
           challenges and opportunities

    • Free pre-print version: Loading...

      Abstract: Abstract Antibiotics at sub-therapeutic levels are often used as feed additives to increase the efficiency of feed conversion into milk and meat and/or to prevent disease and metabolic problems. Under realistic feeding conditions, ionophoric antibiotics such as monensin have proven to be the most efficient manipulators of rumen microbiota and fermentation. Despite these desirable effects on animal performance, the use of antibiotics in animal diets has become a public health concern because of their potential role in the emergence of antibiotic-resistant bacteria. In recent years, there has been public concern about restricting or limiting the use of these antibiotics in animal feed and replacing them with natural sources such as essential oils (EO). Essential oils produced by many aromatic plants have antimicrobial effects on a range of microorganisms. Considerable research has been devoted to utilizing the antimicrobial properties of EO to manipulate rumen microbial fermentation to improve feed utilization and reduce the greenhouse gas (GHG) emissions to decrease adverse environmental impacts of the livestock production. Despite in vitro studies have demonstrated antibacterial activity of essential oils, exhibiting their ability to induce changes in rumen fermentation and improve feed utilization, most in vivo studies have failed to show significant effects on nutrient utilization and animal performance owing to the delayed adaptation within the rumen microbial communities. Current review underscores the opportunities and challenges associated with the use of EO as a potential feed additive for ruminant animals to enhance their health and productive performance. Additionally, this review also highlights the challenges related to the practical application functional efficacy of EO.

  • Prioritization of sub-watershed using geospatial techniques and WSPM model
           in Mandakini River basin, Uttarakhand, India

    • Free pre-print version: Loading...

      Abstract: Abstract The integrity of a watershed is majorly contributed by soil and water; those are essential to thrive sustainably in a hilly area like Uttarakhand. With geoinformatics techniques mapping and estimation of hazard-prone areas can be done. The current study is based on the prioritization of sub-watersheds (SW) by using a correlation-based approach named the weighted sum priority model (WSPM) by utilizing Cartosat DEM. The Mandakini River Basin was delineated into 5 major sub-watersheds to study morphometric attributes, i.e., linear, areal, and relief parameters. The mean estimation of drainage density (Dd) is 2.51 and Stream frequency (Fs) is 4.46. Fs and Dd show positive correlation with other linear and areal parameters (0.83). Elongation Ratio (Re) values for SW 01 and SW05 shows oval shape of sub-watershed. The Form factor (Ff) value of SW 04 featuring a gradual rise and prolonged flow. The cumulative rank for all SW has been computed using the WSPM model, reveals the SW3 and SW4 have the highest priorities for soil erosion among all the rest of the sub-watersheds. This comparative study approaches planners and government officials to assist in decision-making for erosion conservation structures and also in the prediction of hazard-susceptible zones.

  • The role of thioredoxin system in the maintenance of redox homeostasis in
           Mycobacterium tuberculosis

    • Free pre-print version: Loading...

      Abstract: Abstract Maintenance of intracellular redox homeostasis is pivotal for the survival of an organism. During intricate host–pathogen interactions, pathogens typically encounter a barrage of oxidative assault from the host. Therefore, the successful evasion of the pathogen from the hostile environment relies on the efficiency of its redox response system. Mycobacterium tuberculosis, the etiological agent of tuberculosis, confronts redox imbalance mediated by reactive oxygen species (ROS) and reactive nitrogen species (RNS), as well as hypoxic conditions within the host. This review focuses on the survival strategies employed by M. tuberculosis in the redox-imbalanced environment of the host. The initial section of this review centers on the thioredoxin system of M. tuberculosis, which encompasses thioredoxin reductase along with thioredoxins (TrxB and TrxC). Various physiological targets of thioredoxins and the strategies employed to modulate them are described. The subsequent section of this review addresses multiple aspects of hypoxic conditions encountered by M. tuberculosis within the granuloma. This section delineates factors involved in the regulation of hypoxia, such as Rv0081, a transcriptional hub protein, and GroEL1, a chaperone protein. The collective information presented here offers a concise overview of the redox systems of M. tuberculosis that enable it to cope with oxidative stress (primarily the thioredoxin system) and hypoxia.

    • Free pre-print version: Loading...

      Abstract: Abstract Genetic diversity and population structure are essential aspects for understanding the evolutionary history, conservation as well as species diversification in freshwater aquaculture. This study aimed to investigate the genetic variation and population structure of Ompok bimaculatus, commonly known as the butter catfish, using mitochondrial DNA markers, i.e., cytochrome b and ATPase 6/8 genes, as well as their concatenated sequences. The Cytochrome b, ATPase 6/8 and combined genes revealed a large number of haplotypes and low nucleotide diversities. AMOVA results indicated a high level of variance, attributed to differences within populations with significant FST values and the presence of population structure in natural populations. High levels of genetic differentiation within populations of O. bimaculatus were observed. Population-specific haplotype highlighted genetic differentiation among the four studied natural populations, which indicated the presence of distinct genetic characteristics within each population. Molecular variance analysis and pairwise FST values based on cyt b (FST: 0.02227 to 0.58236), ATPase 6/8 (FST: 0.000 to 0.28410) and concatenated (FST: 0.00504 to 0.41511 (Gomti-Kaveri)) further confirmed the genetic differentiation and population structure. The findings of this study provide valuable insights into the species’ genetic characteristics, which can aid in the development of targeted conservation strategies to preserve genetic diversity and ensure the long-term viability of O. bimaculatus populations.

  • Effect of anthropogenic disturbance on biomass allocation to different
           above- and below-ground vegetation components of a dry tropical forest in
           India

    • Free pre-print version: Loading...

      Abstract: Abstract Biotic and anthropogenic disturbances are mediating changes in species diversity and vegetation composition in different regions of the world. Such changes may affect plant biomass allocation patterns in different tree components and vegetation types. To assess the impact of anthropogenic disturbances such as grazing, lopping, harvesting of non-wood forest products, fuel wood and fodder collections on biomass allocation to different components of the vegetation, two study sites i.e., one undisturbed site and the other a disturbed site located in the Barnawapara Wildlife Sanctuary, Chhattisgarh were selected. Biomass allocation was measured by placing ten (10 m × 10 m) quadrats randomly, at both the forest sites (i.e., disturbed and undisturbed). Based on the regression equations relating tree circumference to dry weight of components (viz., bole, branch, leaf, and root), biomass of different vegetation components (i.e., above- and below-ground) was measured. Total biomass (above- and below-ground, including herbaceous shoots and litter mass) was significantly (P < 0.05) higher on the undisturbed site (360.38 t ha−1) compared to the disturbed site (113.99 t ha−1). Among different above-ground components, most of the biomass was allocated to branches followed by bole and leaf. Above-ground biomass ranged between 76.47 and 270.87 t ha−1 with higher value at undisturbed forest site and the lower at the disturbed forest site. The below-ground biomass varied between 37.52 and 89.51 t ha−1, and like above-ground biomass it was also higher at the undisturbed forest site and lower at the disturbed forest site. A higher (~ 8%) biomass allocation to below-ground component was observed at the disturbed site, compared to the undisturbed site. Moreover, the proportion of biomass in the herb layer was higher at the disturbed site compared to the undisturbed site. Based on the results of present study, it can be concluded that under the disturbed conditions plants allocate major portion of the biomass to the below-ground and herbaceous components in the tropical dry deciduous ecosystems.

  • Assessing the stability of slopes in municipal solid waste landfills

    • Free pre-print version: Loading...

      Abstract: Abstract In this investigation, we focused on geotechnical aspects concerning the static and dynamic slope stability analyses for a landfill during the final stages of construction under worst-case conditions. To ensure accuracy, we accounted for varying mechanical and physical characteristics of the buried wastes at different depths, which were determined through a combination of field investigation and literature data. For the dynamic analysis, we employed a Newark-type approach to calculate the permanent displacement of the buried wastes when subjected to a critical artificial earthquake. Subsequently, Newmark analyses were conducted to evaluate the sliding potential of the landfill cover and the critical wedge, enabling us to assess the yield acceleration and time history of permanent displacements. The comprehensive analysis outcomes have been instrumental in evaluating the landfill's overall static and seismic stability and assessing the adequacy of the design slopes. The study’s findings hold significant implications for ensuring the landfill’s safety and appropriateness under critical loading conditions.

  • Quantitative assessment of morphometry and GIS integrated RUSLE
           model-based soil loss estimation from Pahuj river basin, central India

    • Free pre-print version: Loading...

      Abstract: Abstract In this study the morphometric indices of the Pahuj river basin (PRB) were evaluated by applying remote sensing and GIS. The Shuttle Radar Topographic Mission (SRTM) based 30 m digital elevation (DEM) data was used in order to extract morphometric parameters using standard methods. The PRB covering an area (3648 km2) and is controlled by homogenous lithology and geological structures. The drainage density indicates that the permeable soil with coarse texture is dominantly occurring in large low-lying flat areas of the basin. Contrary to this the high gradient consist of impermeable hard granitic rocks of Neoarchean to Precambrian age with a low quantity of permeable soil. The low value of elongation ratio and form factor reveal that PRB is elongated and show low peak flows. To assess the soil erosion susceptibility, the morphometric attributes and a Revised Universal Soil Loss Equation (RUSLE) model integrated with the GIS was used in order to estimate soil loss from the basin. The results of rainfall erosivity (R-factor) along with rainfall pattern indicate that the upper Pahuj catchment relatively exhibits a high intensity of erosion and rainfall than the middle and lower region. The findings of of rainfall erosivity (R), soil erodibility (K), topographic (LS), and crop management (C) factors infer that the soil loss is quite low in the study area. The low value of the ruggedness number and Melton ruggedness (4.16) imply that the basin is moderately rugged and less prone to erosion, particularly in the high relief catchment area. The effective practices of water and soil conservation will enhance water storage capacity and prevent soil and sediment loss in the PRB. The research findings may be helpful to resolve the water crisis and can enhance the effective management of soil conservation in such a drought-prone area.

  • Antibiotic resistance genes on raw egg surface with potential to transmit
           through supply chain

    • Free pre-print version: Loading...

      Abstract: Abstract In this study, the occurrence of tetracycline resistance genes among bacteria present on the raw egg surface was analysed. Metagenomic method was used in this study for the rapid detection and better surveillance on antibiotic resistance transfer. From the study, meta DNA extracted from the raw egg surface wash was found to be positive for tetB gene. Whereas the meta DNA from the poultry slaughter house cutting surface, was found to have both tetA and tetB genes. The antibiotic resistance pattern of bacteria isolated from the raw egg samples further showed 76% of them to be resistant to more than 3 different categories of antibiotics. As the antibiotics used in the poultry feed are known to contribute to the fast emergence of resistance in bacteria associated with poultry derived food, it is important to rigorously monitor the feed in poultry farms in order to minimise the rapid spread of antibiotic resistance.

  • Mesozoic tectonics of the Indo-Burmese wedge: a record from the
           high-pressure metamorphic rocks of the Nagaland-Manipur Ophiolite Belt, NE
           India

    • Free pre-print version: Loading...

      Abstract: Abstract In this study, we make a review of the recent developments on the metamorphic and tectonic evolution of the Nagaland-Manipur Ophiolite Belt (NMOB) in the Indo-Myanmar Ranges. We collate key metamorphic findings and chronological constraints in the NMOB to demonstrate an exceptional record of the full life cycle of the thermal and dynamic history of the Early Mesozoic intra-oceanic subduction system within the eastern arm of the Neo-Tethys from its infancy to its cold-mature stage. The earliest stage of an Early Jurassic-aged oceanic subduction under warm thermal conditions (apparent peak thermal gradient of ~ 20 °C/km), and within the first 1–2 Myrs since subduction initiation is recorded in the newly discovered high- and low-temperature metamorphic sole rocks of the Tusom CV area in the Manipur segment of the ophiolite belt. The metamorphic sole sequence, comprising a package of ultra-high temperature mafic granulites → high-temperature mafic granulite → garnet + clinopyroxene-bearing amphibolite → garnetiferous amphibolite → non-garnetiferous amphibolite → epidote amphibolite and low greenschist facies metasediments, and structurally downward, constitutes an inverted metamorphic sequence. Tectonic slices of hornblende eclogite facies metasediments and metabasites from diffrrent locations in the Nagaland segment of the Ophiolite Belt, on the other hand, reveal an apparent peak thermal gradient of ~ 12–15 ℃/km, indicating an intermediate subduction cooling stage. The structurally upward metamorphic sequence of greenschist facies → pumpellyite-diopside facies → lawsonite blueschist facies and epidote eclogite facies, the latter locally reaching ultra-high pressure metamorphic conditions in metabasalts of the structurally lowermost unit of the Nagaland ophiolite mélange together record a cooler apparent peak thermal gradient of ~ 7–8 ℃/km. We relate this metamorphism with the end stage of the Early Jurassic-aged intra-oceanic subduction, when the Neo-Tethys evolved into a cold-mature stage of subduction.

           farming in the Eastern Himalayan region of India

    • Free pre-print version: Loading...

      Abstract: Abstract The non-availability of efficient buckwheat genotypes is a challenge to achieve higher productivity under organic farming. Hence, this study was undertaken during three consecutive rabi seasons (2016–19) in the Sikkim state of the Indian Himalayas to evaluate the agronomic performance of different buckwheat genotypes under organic farming. Twelve buckwheat genotypes were tested in three times replicated randomized block design. Results revealed that among the buckwheat genotypes, PRB-1 had the tallest plant (68.3 cm) while IC 109729 had the shortest (41.8 cm). However, the maximum above-ground dry matter accumulation (10.7 g plant−1) and leaf area index (2.59) were noticed in IC 49671 followed by IC 109433. While the chlorophyll content (2.08 mg g−1) was highest in Sangla B-1. Local Meethay was short duration (78 days) buckwheat genotype while Sangla B-1 took the maximum number of days (113 days) to attain maturity. The highest number of branches plant−1 (12.8) and seeds clusters plant−1 (28.7) was recorded in IC 49671. The maximum production efficiency (14.2 kg ha−1 day−1), profitability (649.6 US$ ha−1 day−1), and the nutrients’ acquisition (122 kg N ha−1, 30.5 kg P ha−1 and 98.8 kg K ha−1) were recorded under IC 49671 closely followed by IC 109433. Overall findings suggested that the buckwheat genotype IC 49671 and IC 109433 are suitable candidates for organic cultivation in the Eastern Himalayan region of India.

  • A holistic approach of remote sensing, GIS, and machine learning for
           shallow landslide susceptibility mapping in Gaganbawada region of Western
           Ghats, India

    • Free pre-print version: Loading...

      Abstract: Abstract Every year, the Western Ghats region experiences devastating landslide disasters that are closely linked to the region’s wealth and growth, resulting in the loss of lives and damage to private and public property. Thus, it is important to identify the highly vulnerable places to minimize these losses. The major objective of this present research is to create a reliable landslide susceptibility map for the Gaganbawada region of Western Ghats. Support vector machine (SVM) is the machine learning based algorithm used to demarcate landslide susceptibility zones using a holistic approach of remote sensing and geographical information system. At first, the landslide inventory map is produced using Google Earth images and field studies. A total of 170 landslide (85) and non-landslide (85) points are used for the training and testing dataset, with a ratio of 70% and 30%, respectively. Secondly, 15 landslide influencing factors are selected. The predictive capabilities of the influencing factors are assessed using the information gain ratio and Pearson correlation coefficient to choose the optimal subset of influencing factors. Subsequently, a landslide susceptibility map is produced using the radial basis function kernel of the SVM model. As per the result, 23% of Gaganbawada’s land area is in the high and very high landslip susceptibility zone, and 50% is in the low zone. The susceptibility map represents that only 8% of the land area is in the very high zone, on the other hand, 70.5% of historical landslides have been recorded. The resulting model is validated using the receiver operating characteristic (ROC), and several statistical evaluation matrices. According to the ROC evaluation result, the SVM model has an area under the curve (AUC) value of 0.88, showing that the present machine learning based model has acceptable prediction effectiveness and landslide susceptibility map result is reliable and effective for implementation.

      Abstract: Abstract The uncertainty of Heisenberg and exclusion concepts are applicable when electron wave functions overlap. Since fermions are affected by a spin force with the Brillouin function, Quantum magneto hydrodynamic equations have been developed for studying the spin force effects on the system. The Normal Mode Analysis method is used to solve the QHD equation for nonrelativistic degenerate inhomogeneous quantum plasma. Following linearization, the first order perturbation of the densities and velocities of plasma species are observed, which are used in Poission’s equation to obtain dispersion relation. Influence of spin force using Brillouin function for half spin particles along with Bohm Potential will be observed in a quantum plasma model consisting of degenerate electron along with non-degenrate positive ions. The results will have impact on both plasma-aided nanotechnology and the dispersion relation for quantum plasma instability

Compared to aquatic bodies, the evidence of MP contamination in terrestrial environments has received less attention. However, despite the high likelihood of MP contamination in India, there is a paucity of available evidence from the research based study. The main sources of microplastic pollution in agricultural fields are the application of sewage sludge as fertilizers, soil mulching and sewage wastewater irrigation. The findings of this investigation offer preliminary proof that MPs contamination present in the sewage wastewater. The present study found that a total number of 291 microplastics present in all the experimented soil samples. The microplastic particles were found to be different in size, shape, and color. Microplastics particles were found to belong to five different polymer classes, including polyethylene, polypropylene, polystyrene, polyethylene terephthalate, and polyvinyl chloride, according to chemical analyses of their composition. According to this study, MPs are a rather long-lasting result of human-induced activities that might profoundly alter terrestrial ecosystems.

  • Geophysical and geochemical studies on sinking stream occurrence in
           Ayankulam village of South Tamilnadu, India

      Abstract: Abstract The severe monsoon flooding in 2021 exposed the intricate hydrogeological processes affecting groundwater resources near Ayankulam village in the semi-arid terrain of South Tamil Nadu, India. Despite extensive inundation from overflow of the Nambiar canal, the village well remained dry due to diversion of recharge away from shallow aquifers into deeper concealed karst formations present in the underlying calcarenite bedrock. Detailed geophysical surveys utilizing Azimuthal Square array resistivity combined with Magnetotellurics successfully identified and mapped subsurface pathways of sinking streams that rapidly transported surface water vertically into deeper fractured basement aquifers instead of laterally recharging the shallower dug well. Geochemical analysis of groundwater samples collected from wells in the area revealed progressive evolution of ionic compositions along groundwater flow paths dominated by water–rock interactions including carbonate mineral dissolution, silicate weathering, cation exchange and evaporation. Findings indicated that excessive recharge from heavy rainfall events caused accelerated subsurface drainage of fresh groundwater away from inland recharge zones near Ayankulam village towards the coast. This rapid drainage driven by the hydrostatic pressure exerted by the intense monsoon recharge on the highly permeable karst conduit networks buried beneath the low permeability overlying clay-rich soils. The diversion of freshly recharged water from the surface into deeper aquifers before it could reach the shallow dug well resulted in the phenomenon of “dry fallout” observed in Ayankulam village. This integrated geophysical and geochemical study provided evidence that sinking streams and the complex linkage between shallow and deeper aquifers control groundwater occurrence and movement in the region. The findings emphasize the need for enhanced monitoring and measurement of hydrogeological parameters coupled with integrated water resources management. This is vital for sustainably harnessing water resources amidst growing demands from the increasing population and intensifying climate change pressures that exacerbate rainfall variability.

  • Triassic non-marine vertebrate diversity of India: status report
           (2020–2024)

    • Free pre-print version: Loading...

      Abstract: Abstract Just after the end-Permian Mass Extinction Event, the onset of Triassic period records an impoverished terrestrial vertebrate diversity end-Permian extinction event that is succeeded by the advent of new and diverse faunas that peaked during the Late Triassic. Such variations in vertebrate diversity is also reflected in the fossil record of the Gondwana basins of India. In a span of four years (2020–2024), multiple work from India has considerably enhanced this Triassic vertebrate record by addition of various new tetrapods. This included a proterosuchian from the Early Triassic, a large, herbivorous and horned azendohsaurid and an erythrosuchid from the Middle Triassic, and various phytosaurs, aetosaurs, a dome-headed archosauromorph and a small carnivorous azendohsaurid from the Late Triassic. These studies highlighted the biostratigraphic and biogeographic significance of the fossil finds and helped in the better understanding of the Triassic scenario of India.

  • An overview of recent research on the fossil biota of the Deccan Volcanic
           Province, India

    • Free pre-print version: Loading...

      Abstract: Abstract The Deccan volcanism of India, representing one of the largest flood basalt provinces of the world, has attracted wider attention in recent years because of its supposed role in the mass extinction at the Cretaceous-Palaeogene (K/Pg) boundary. In this context, flora and fauna recovered from the sedimentary beds deposited immediately before the initiation of Deccan volcanism (infratrappean beds) and those deposited during quiescent stages of volcanism (intertrappean beds) assume great significance in understanding the effects of the volcanism on contemporary biota, biogeographic origins and distribution of different taxonomic groups, and the role of volcanism in K/Pg boundary mass extinction. In this paper, a detailed review of the research done on these aspects in the last 4 years is presented.
