Subject: Camera traps reveal coat colour variation in an isolated population of golden jackals
Keywords: Coat colour variation, golden jackal, hybridization, isolated populations.
Abstract: Long-term monitoring of glolden jackals along the coastline of the southern Western Ghats, India, Provided interesting results. We observed various coat colour patterns such as leucism, melanism, semi melanism and rusty coats among jackals resembling dogs. The melanistic variation and rust colour expression may be due to the acquired genetic properties during crossbreeding with the free-ranging dogs, as the associated mutations have been previously documented in dogs and not in jackals. Genetic studies can assist us in understanding the causes and consequences of coat colour variation.

Keywords: Breeding lines, genomic regions, mapping population, pigeon pea, quantitative trait loci.
Abstract: Multi-parent advanced generation intercross (MAGIC) population is a powerful resource for genetic studies, molecular mapping and development of high-yielding pigeon pea genotypes. In this study, eight diverse pigeon pea genotypes were used as founder patents and crossed in two, four-and eight-way approach to develop a MAGIC population, which could be useful for delineating the genomic regions/quantitative trait loci for various traits of interest. The population can also prove useful for selection of high-yielding pigeon pea breeding lines adapted to various agro-ecological regions of India.

Subject: Snow avalanche risk management in Shemshak region: a modelling, mapping and evaluation of factors affecting the occurrence of snow avalanches
Keywords: Hazard and risk maps, mapping and modelling, risk management, snow avalanche
Abstract: In the last two decades, 40 persons have been killed by avalanches in the Shemshak region, Tehran, Iran. The area has also suffered a lot of damage. Here, we have studied 18 variables affecting the occurrence of avalanches in Shemshak region. They are related to the geomorphological, topographic, climatic and snow conditions as well as human activities. The modelling and mapping were performed using various environment al factors and statistics as well as data-driven methods (e.g hierarchical analysis method, maximum entropy) followed by field visits. Finally the conceptual model of avalanche risk assessment was prepared using spatial mapping and HEV approaches. The results showed that avalanche hazard maps are considered as the high-risk and most important areas in the avalanche hazard amps are considered as low-risk areas in the avalanche hazard maps are considered as low risk areas in the avalanche risk map. Based on the obtained results, it can be concluded that due to the complexity of the risk mapping process, it is difficult to use a worldwide benchmark and indicators system to assess hazards and prepare risk maps. Therefore, more research is needed to elucidate the applied risk maps for avalanche hazard management.

Subject: Influence of driver and vehicle attributes on operational characteristics of U-turning vehicles
Keywords: Approaching through traffic volume, driver behaviour, heterogeneous traffic, mid-block median opening, vehicle attributes
Abstract: Mid-block median openings (MBMOs) are provided to take a U-turn, which is a complex process. Tom takes this movement a vehicle has to stop at the MBMO to find a suitable gap in the approaching through traffic stream. Two parameters, namely, service delay9SD) and occupancy time (OT) are crucial operational characteristics of an MBMO, which significantly affect characteristics of an MBMO, which significantly affect traffic operation. The present study examines the influence of driver behaviour and vehicle attributes on SD and OT at six-lane and four-lane divided roads. From statistical analysis, SD was observed to be less at low approaching through traffic volume (ATTV) compared to high ATTV, where as OT was observed to be high at low ATTV, and it decreased with increase in ATTV. Male drivers showed aggressive drinking behaviour compared to female drivers, and the same was validated using a two-tailed t-test. Moreover, personal vehicles were found to behave defensively compared to commercial vehicles. Also, loaded vehicles were observed to turn the ring steering slowly being concerned about the safety of their passengers and goods compared to empty vehicles. The findings of this study will be beneficial in validating simulation results, defining level of service etc. for planners in regulating the traffic efficiently.

Abstract: We provide a methodology for assessing short-term mitigation targets for a region against long-term global goals for addressing climate change. We first estimate the per capita fair share of the remaining carbon budget for India from 2018 onwards. Potential long-term emissions trajectories between 2018 and 2100 compatible with this fair share are then constructed. These budget-compatible trajectories are then compared to the Nationally Determined Contribution (NDC) as well as results from five modelling studies for India. The methodology discussed here can be used to assess the adequacy of NDCs and also helps in rationalizing the process of target setting for climate action.

Abstract: The present study aims to uncover the alpha-glucosidase inhibition (AGI) and antioxidant activities of Ensete superbum seed extract. The AGI activity of crude extract (IC50 =0.17 µg/ml) and silica gel column purified fraction (ESSFR4; IC50 =0.17 µg/ml) was excellent when compared to acrbose (IC50 =1720 µg/ml). Also, the free radical scavenging ability of ESSFR4 was comparable to ascorbic acid. Among the five compounds identified from ESSFR4, pentasiloxane, dodecamethyl and 2, 4-hexadienedioc acid, bis (trimethylsilyl) ester, had the best binding affinities against human and yeast AG enzymes respectively. However, ADME/toxicity evaluation of these five compounds revealed that they would require further structural scrutiny and in vivo studies before recommending them as an alternative to the present AGIs to treat type-2 diabetes.

Subject: Techno-economic analysis of irrigation systems for efficient water use in the backdrop of climate change

Abstract: In view of the growing water scarcity, particularly in the backdrop of climate change in the adoption of water-efficient irrigation systems is becoming indispensable. The study of efficient irrigation systems is lacking in the developing countries like India, which is in turn responsible for the low values of water-use efficiency in agriculture. Therefore, in this article, different irrigation systems studied for the developing countries, including the water-efficient and traditional ones, are reappraised. The irrigation systems are assessed on the basis of various factors such as economic parameters, water productivity, water saving and crop yield. Among water-efficient irrigation systems, drip irrigation system (DS) is considered to be the most successful method for water conservation and increased agricultural output.DS not only reduces the cost of supplied water, but also those incurred in the activities such as human labour and their cultivation costs.DS is found suitable for a variety of crops, including cereals, vegetables and cash crops in different regions of the world. Water saving and electricity saving is in the range 40-54% and 26-47% respectively, when DS is compared with the surface irrigation is found to be the most robust, profitable and cost-effective method of irrigation and could be a possible solution to the growing water shortage in the backdrop of climate change.

Abstract: Globally, sustainable management of agricultural waste is a great challenge, especially in developing nations like India with a burgeoning population, production rate and economic growth. India generates more than 500 million tons of crop residues annually. Residue burning is a major environmental concern contributing to global warming, health issues, loss of valuable nutrients and soil biota. Intensive cultivation with the use of high-analysis straight inorganics alone has resulted in imbalanced fertilization, multiple nutrient deficiencies and soil degradation. There is an ushering need for alternate sources of organic due to the shortage of good quality farmyard manure (FYM) owing to the decline in cattle population in rural areas.

Abstract: Human-elephant conflict is a major conservation issue in elephant-range nations. A number of management methods have been developed and are now in use to avoid and mitigate this conflict. Human-elephant conflict continues to be wide-spread as the bulk of the present preventive techniques is based on site-specific elements that only provide short-term solutions, whereas mitigation strategies typically shift conflict risk from one location to another. Conflicts are more common in or around conservation zones that are close to densely human-inhabited regions. Elephant populations are close to humans in villages on the edge of national parks, communities bordering forest reserves and settlements within the reserves, and so confrontation are serious. Conflicts are common when human infringe on animal habitats, such as farming in an elephant travel corridor, and when elephant food sources are depleted, forcing it to adapt to new condition.

Keywords: Biodiversity hotspot, dung beetles, molecular phylogeny
Abstract: The tribal and generic-level phylogeny of Scarabnaeinae (Coleopera: Scarabaeidae) dung beetles have been often debated globally. However, fauna from India have not been a part of these analyses due to lack of data. We used partial sequences of 16 S mt DNA gen of dung beetles collected from different part of the Western Ghats, India, to examine (1) the tribal positions of Onthophagini, Onitini and Oniticellini, and (ii) the phylogenetic position of different genera of Onthophagini, suggesting the invalid position of Oniticellini.The non-Onthophagus genera of Onthophagini-Caccobius, Cleptocaccobius, Milichus-nested within Onthophagus, suggesting that these three genera might be invalid and could be subgenera of Onthophagus. Onitini formed a separate clade in the phylogenetic tree. The results suggest for tribal-level reclassification of dung beetles, as noted in previous studies. The present study may enrich the molecular data of the Indian dung beetles, which are currently lacking.

Subject: Habitat suitability analysis for blackbuck (Antilope cervicapra) in Nahar Wildlife Sanctuary, Haryana, India
Keywords: Bioclimatic variables, blackbuck, habitat suitability, remote sensing, spatial distribution
Abstract: Remote sensing and GIS play an important role in wildlife species conservation through their applicability to study spatial distribution, landscape pattern and also factors that affect the distribution, density and movement of wild fauna. The present study deals with the distribution of blackbuck (Antilope cervicapra) in Nahargarh Wildlife Sanctuary, Haryana, India, and to determine their habitat suitability which is shrinking due to the spread of settlements (urban and rural).For habitat suitability analysis of blackbuck, data from WorldClim,19 bioclimatic variable layers such as temperature , humidity , precipitation, etc. were utilized to calculate the maximum entropy using MaxEnt version 3.2.Satellite data from Landsat 8 were used to generate land use and land cover for analysing habitat suitability. An area of 330.71 ha was found to be suitable for blackbuck habitat within the 10 km buffer area, against the present area of 28.32 ha. The growth of Prosopis juliflora which causes damage to the skin of blackbuck during movement was found to be another factor responsible for confining its niche within the Sanctuary. The present study will help in the effective safeguarding of blackbuck species by the Wildlife Wing of the Haryana Forest Department.

Subject: Soil quality mapping in the groundnut belt of erstwhile Mahabubnagar District, Telangana, India using GIS
Keywords: Crop colonies, groundnut, micronutrients, soil quality maps, yield gaps.
Abstract: The present study was conducted during rabi season of 2019-20 based on the crop colonies concept, where the highly and marginally potential regions for ground nut were delineated with an objective of soil fertility assessment in the crop area in order to determine the yield gaps and constraints for low yields in marginally potential areas. Soil samples collected at 35 GCP sites through preliminary crop survey in homogenous, contiguous groundnut areas at the time of crop-cut experiments were analysed in the laboratory for soil quality parameters. The results revealed that the soils were slightly saline (pH:7.50-8.50) with low saline EC (<0.25 dsm-), high organic carbon content (>0.75%), acutely deficit available nitrogen (<100 kg ha-1), high phosphorus (>24.6 kg ha-1) , medium potassium (108-280 kg ha-1) and low Sulphur (<10 MG kg-1).The DTPA extractable micronutrients-zinc, manganese and copper were sufficiently high (Cu>0.20 mg ka-1; Zn>0.65 mg kg-1 and Mn>2 mg kg-1), while iron was low (<4 mg kg-1). Based on the results of laboratory analysis soil quality maps were generated using QGIS software, wherein each parameter was grouped into several classes based on USDA soil classification employing IDW interpolation technique.

Subject: Public perception of flood risks and warnings in the flood-prone Kashmir Valley, India
Keywords: Flood forecasting and warning, public perception, question-based survey, risk estimation
Abstract: Floods are the most recurrent of all natural disasters in Kashmir Valley, Jammu and Kashmir, India, affecting both society and economy. Despite various efforts to prevent loss of lives and assets during floods, a crucial component of flood management, i.e., how the inhabitants perceive flood risk, is not well-known in the region. A questionnaire-based survey was conducted in flood-prone regions of the Valley to gain information on how public understands the risks of flooding in their area, their flood preparedness, knowledge about floods and the trust in various institutions for managing floods and disseminating flood warnings. Respondent demographics was then linked with their answers to establish potential correlations. Responses illustrate that the respondents consider floods as the most important natural disaster in the valley and most of them mention that the risk is increasing. Results show that the respondents have average knowledge regarding floods, flood protection measures and emergency actions in case of floods. At the individual level, they had not taken adequate steps for safeguarding themselves or their families against floods. The characteristics lf respondents namely age, gender, income, education level and previous experience with floods showed statistically significant correlations with the responses. In general, the findings of the study call for better education of the inhabitants regarding flood risks and management actions as well as improvement of existing methods of flood forecasting and warning in the region.
