Subject: Gut microbiota in human metabolic health and diseases: current perspective and impending aspects
Keywords: None
Abstract: The urban lifestyle results in various metabolic abnormalities, including metabolic syndrome, non-alcoholic fatty liver disease and polycystic ovary syndrome. A complex ecosystem of bacteria living in the gastrointestinal tract – the gut microbiota, is essential for many physiological processes, such as immune system modulation and nutrition metabolism. Changes in the richness and composition of the gut microbiota have been linked in recent research to the onset and course of metabolic syndrome, a group of illnesses that includes hypertension, insulin resistance, obesity and dyslipidemia. It is possible to design targeted therapies, such as probiotics or dietary regimens to alter the microbiome and perhaps reduce the risk or severity of metabolic syndrome by understanding the complex pathways by which gut microbiota influence the condition.

Keywords: None
Abstract: The book under review begins with a preface documenting the background and importance behind writing this book on diversity of parasite fauna of Kashmir Himalayas. Considering the biological and ecological significance of parasites around which the contents of the book are centred, the book assumes high-order value in the field of academia in general and biological diversity in particular to increase awareness and understanding of parasite diversity. This reference book based on up-to-date research work of last few decades has the potential to fill the existing critical information gap in the field of parasite biodiversity and overall biological diversity in Kashmir Himalayas. It is interesting to know that about 40–50% of the living organisms live as either ectoparasites or endoparasites on/in different kinds of other living organisms (hosts) to fulfil their metabolic needs/ other life requirements and at the same time are responsible for causing a variety of parasitic diseases in their hosts.

Subject: Invasive plant in an anthropogenic disturbed and a community protected forest and their means as bio-resources
Keywords: Bioresources, Eastern Himalayas, invasive alien plants
Abstract: The present study deals with an exploratory survey on the uses and role of invasive alien species (IAS) in the local Naga livelihoods in the mountainous region of eastern Himalayas. IAS was randomly sampled from an anthropogenic disturbed forest and a community protected forest to comparatively analyse the type of IAS prevailing in those conditions. Later, group discussions were arranged with local inhabitants to distinguish and identify the various uses of IAS. A total of 31 plant species belonging to 18 different families were identified, out of which 21 species were reported to be used as bio-resources. The majority of the identified species were found to possess medicinal or curative properties. Considering the importance of IAS despite some of their negative impacts, it is important to impart traditional knowledge of their uses to the upcoming generations and initiate necessary steps to distinguish harmful species from harmless ones for better ecological sustenance.

Subject: Evaluating environmental and remote sensing factors in theileriosis risk prediction for bovine in Kerala, India: navigating post-flood climate dynamics
Keywords: Disease prediction, Kerala, livestock, machine learning, outbreak, theileriosis.
Abstract: Theileriosis, a parasitic disease, caused by Theileria spp. and transmitted through ticks, poses a significant threat to livestock, leading to elevated morbidity and mortality rates. This study investigated the incidence trend of theileriosis in Kerala, India, over three years (2019–21). Notably, the research unveiled a substantial upsurge in bovine theileriosis cases within Kerala during this period, partly attributed to the state’s severe flooding and landslides in 2018, triggered by incessant monsoon rains. The present study envisaged pinpointing the risk factors underlying the prevalence of theileriosis in Kerala. Employing linear discriminant analysis, key environmental and remote sensing variables influencing the disease’s incidence were identified. Subsequently, these risk factors underwent climate disease modelling, leading to the creation of risk maps. To predict areas sensitive to theileriosis outbreaks in Kerala, two regression models and nine machine learning models were employed. The gradient boost and random forest models demonstrated the most accurate fit among these. The study also estimated the basic reproduction number (R0), which ranged from 0.89 to 1.8. This value indicates a high potential for Theileria spp. transmission within the study area. Consequently, the research outcomes offer valuable insights into pinpointing high risk theileriosis locations in livestock in Kerala.

Subject: Prediction of drought – risk zones in Tamil Nadu using historical and global climate model data
Keywords: Drought events, drought forecast, Indian Meteorological Department, standardized precipitation index
Abstract: Global climate change has increased the events and intensity of extreme events. Tamil Nadu is located in the southern peninsula region of India, which has benefitted both from the south-west monsoon (SWM) and the north-east monsoon (NEM). Although variations in the monsoon pattern increased events of drought. The IMD gridded (1991–2020) and projected global climate model data (EC_Earth3_Veg_LR) were used to anticipate the drought-risk-prone zones over Tamil Nadu by using the standardized precipitation index. During both the SSP245 and SSP585 scenarios of the near (2021–2050) and mid (2051–2080) century periods, an increase in rainfall amount was expected with a high coefficient of variation (CV) across the region. The CVs of the future SWM and NEM seasons were expected to range from 20% to 60% and 25% to 50% respectively. Increased variability often leads to an increase in number of drought events. Regardless of scenarios, the southern zone was expected to experience more drought events, followed by the northwestern zone during SWM. Drought events during the NEM were expected to increase in northeastern zone districts. Changes in cropping patterns and policymaking for future risk-prone areas were undertaken as a proactive response to mitigate potential agricultural challenges.

Abstract: National Innovations on Climate Resilient Agriculture (NICRA) is a flagship project of the Indian Council of Agricultural Research (ICAR) to mitigate climate change in vulnerable districts of India. The present study assessed farmers’ satisfaction with climate-resilient agricultural technologies following their adoption in two vulnerable districts of Telangana, India, identified under the NICRA project. Results showed that most farmers in the Suryapet and Khammam (62.67% and 90.00%) districts of Telangana state expressed high satisfaction with these technologies. Additionally, a significant proportion had a highly favourable perception of the technology promoters (71.33% and 82.00%), high perceived expectations (52.67% and 74.00%), high perceived quality (58.00% and 86.00%), and a high perceived value (68.00% and 84.00%) associated with climateresilient agricultural technologies. Importantly, the vast majority of the farmers in both districts expressed their intent to use these technologies when the need arises. Path analysis revealed that variables like perceived image, perceived expectation, perceived quality and perceived value had a significant direct impact on satisfaction, while there was no indirect effect on behavioural intention.

Abstract: We characterized the complete mitogenome of Nemipterus randalli and performed comparative mitogenomic analysis with previously determined mitochondrial genomes belonging to the family Nemipteridae. Using Sanger sequencing, we identified a 16,642 bp mitogenome containing 37 genes (13 protein-coding, 2 rRNA, 22 tRNA) and a non-coding region. Its gene organization, nucleotide composition, tRNA secondary structure and codon usage are similar to other Nemipteridae mitogenomes. The phylogenetic analysis indicated that Nemipteridae is a monophyletic group. The present study forms the basis for further studies on the population genetics, evolution and phylogeny of N. randalli and its family.

Keywords: Athaphum, Loktak, Meitei, Ramsar, spatiotemporal dynamics
Abstract: As the largest freshwater lake in the region and a designated Ramsar site, Loktak lake in northeast India holds paramount ecological and socioeconomic significance, particularly for the indigenous Meitei community. This study delves into the intricate spatiotemporal dynamics of a traditional fishing technique called athaphum practised by the Meitei community in the Loktak. It utilizes the normalized difference vegetation index derived from the remote sensing satellite images to discern the athaphum and its trend over the past three decades (1988–2023). Our findings reveal significant fluctuations in athaphum due to ecological, hydrological and human factors. The findings of this study enhance our understanding of the complexities involved in safeguarding Loktak lake. They shed light on the intricate balance needed to sustain environmental integrity and socioeconomic well-being in the Loktak region.

Subject: Empirical evidence for shifting cultivation’s role in indigenous food sovereignty in Manipur, Northeast India
Keywords: Agrobiodiversity, ethnic foods, indigenous food sovereignty, jhum cultivation, Northeast India.
Abstract: Indigenous food sovereignty (IFS) is pivotal in enhancing food security and nutritional well-being and preserving governance systems and cultural practices within indigenous communities. Despite its significance, the literature on food sovereignty practices within Indian tribal communities and strategies for bolstering them remains limited. The present study draws upon primary data collected from 97 households in Manipur, Northeast India to address this gap. This study employs a mixedmethods research approach and systematically investigates the intricate dynamics of shifting cultivation (SC), agrobiodiversity and their collective contributions to IFS. Empirical findings underscore that SC provides culturally relevant food resources, thereby amplifying dietary diversity and contributing significantly to IFS. The indigenous SC system in the present study site encompasses 32 crop species and 4 local livestock breeds, featuring numerous landraces that ensure nutritional security and preserve food culture. Integrating wild edible plants from forests and fallow lands supplements the traditional food basket, reinforcing indigenous food culture and promoting biodiversity conservation. This study emphasizes the symbiotic relationship between SC-based agrobiodiversity and dietary diversity and highlights their critical role in fortifying IFS resilience, particularly in the context of climate change.

Abstract: The effectiveness of a hybrid unmanned aerial vehicle (UAV) for optimizing crop booster application on cotton crops (variety Co-14) at Tamil Nadu Agricultural University is evaluated in this research. The hybrid UAV, featuring a 12-litre sprayer tank and powered by an internal combustion engine and brushless direct current motor, was tested at heights of 1 and 2 m and speeds of 3 and 4 m s –1 . The objective was to determine optimal parameters for maximizing droplet deposition and minimizing spray drift. The results indicated that at 1 m and 3 m s –1 , the droplet density in the target area was 148 ± 8 drops/cm2 , compared to 136 ± 4 drops/cm2 at 2 m. The volume median diameter at 1 m and 3 m s –1 was 361 µm, and the number median diameter was 392 µm, showing higher deposition and uniform droplet sizes at lower heights and lower speeds. Spray drift analysis indicated reduced off-target movement at 1 m and 3 m s –1 , showing a non-target droplet density of 54 ± 4 drops/cm2 compared to 42 ± 6 drops/cm2 at 2 m. The study concludes that the optimal UAV operation parameters are 1 m height and 3 m s –1 speed, enhancing droplet deposition, minimizing drift, and improving spray efficiency.

Abstract: In the modern rubber industry, the major problem is the use of petroleum-derived chemical reinforcements that exploit conventional sources of energy. In this review article, we have discussed the importance of some cellulose-based reinforcements as an alternative to harmful chemicals in rubber composites. The employment of natural cellulosic fillers not only improves the biodegradability of rubber latex but also enhances its mechanical and thermal properties. Such reinforced rubber composites can be used effectively in various sectors, i.e. food packaging, footwear, water purification and sensors. In the last, the current outlook and future perspectives of smart rubber composites in commercial areas are also discussed.
