Subject: Kallar elephant corridor in the Western Ghats, India: trend of human interface vis-à-vis feasibility of wildlife-friendly flyover and land acquisition
Keywords: Elephant corridor, human-interface, traffic intensity, wildlife-friendly mitigation
Abstract: The present account from Kallar elephant corridor is a case-history which elucidates that delay in implementing management recommendations leads to unmanageable trends in land-use pattern, traffic intensity, human–elephant interface, and escalation of costs for management options like land acquisition and engineering structures as flyovers or ‘elephant underpass’. Ultimately, a situation may develop where elephants may take their own course of population reduction, fragmentation and shifting of interface problem to new areas.

Subject: The war against MDR pathogens: move fungi to the frontline
Keywords: Drug resistance, filamentous fungi, novel antibiotics, pathogenic microbes.
Abstract: The evolution and spread of resistance among pathogenic microbes to different antibiotics currently in use is a global health problem. Attempts are being made to tackle this major health burden by involving policy makers, scientists, healthcare professionals, the general public and industry. Several strategies, including improvement of prescribing practices, use of combination therapies and synthetic antibiotics, and development of species-specific antibiotics have been suggested to retard the evolution of drug resistance. However, most of the new antibiotic molecules which are being prepared to be marketed are only modifications of existing ones, thus lacking novelty in their mechanism of action or target sites. It is reasonable to expect that the introduction of totally new antibiotics would delay the evolution of drug resistance. In this context, the filamentous fungi are a promising source of novel antibiotics. Their diverse biochemical pathways, the range of ecological niches they occupy, and that 8% or less of the 2.2–3.8 million estimated fungal species are known, underscore the now urgent need to screen them for novel antibiotics.

Subject: Submarine groundwater discharge in the Indian context
Keywords: Submarine groundwater discharge
Abstract: In India, the demand for freshwater resources is increasing every year because of population rise and rapid economic development. This warrants the imminent need for better evaluation of all the available sources of freshwater and their discharge–recharge mechanisms for planning sustainable development strategies in the country. Among different sources, groundwater constitutes about 97% of the earth’s liquid freshwater in the hydrologic cycle. It has now been realized that as part of the hydrologic cycle, a significant amount of groundwater flows directly into the sea through porous rocks and sediments1 . This component is called submarine groundwater discharge (SGD).

Subject: Response of methane diffusion in varying degrees of deformed coals to different solvent treatments
Keywords: Deformed coal, diffusion coefficient, pore structure, solvent treatment, wettability.
Abstract: In the communication, we analysed four semi anthracite coals with different degrees of deformation from the Huoerxinhe colliery in China that were extracted by tetrahydrofuran (THF) and carbon disulphide (CS2) and treated with hydrochloric acid (HCl) solution. Low-temperature nitrogen adsorption, water contact angle measurement and methane diffusion of untreated coals and their residues were carried out. As well, mineral composition of untreated coals and their residues treated with HCl are performed. Overall, compared with untreated coals, specific surface area has increased tendency after THF and CS2 extraction due to the removal of the soluble organic components in coal, depends jointly on mineral types and their respective content after HCl treatment. Regardless of coal un- or treated by solvents, diffusion coefficient grows with increasing coal deformation. Further study shows that the diffusion coefficient of coal with same deformation increases as follows: HCl treated coal residues, THF extracted coal residues, untreated coals, CS2 extracted coal residues. The aforementioned phenomena result from two aspects: on one hand, the enlargement of pore after solvent treatment reduces the collision between methane molecule and pore walls, thus improving the efficient of methane diffusion; on the other hand, pore is narrowed or even blocked completely due to the retention of foreign matters, which increases the resistance of methane diffusion. Therefore, methane diffusion after solvent treatment is jointly dependent on pore change because of the removal of soluble components and the retention of foreign matters.

Keywords: Chiroptera, Cynopterus sphinx, conspecifics, distress calls, social relationship
Abstract: Distress calls emitted by bats signal their conspecifics either to warn them or inform them about the situations. Conspecifics may also get attracted towards distress calls as a behaviour of cooperative mobbing or just selfishly assessing the potential source of danger. The exact function of distress calls in bats therefore vary to a great degree and are very hard to pinpoint. We conducted playback experiments to test the response of short-nosed fruit bat, Cynopterus sphinx towards the distress calls of their conspecifics from related and unrelated sites. Bats were attracted to their conspecifics from both related and unrelated sites and in one occasion towards fruit bat (Rousettus leschenaulti) of another genus within the same family. The response towards the opposite sex was significant in most of the playback trials and the reasons remain unclear. This symmetric response towards conspecifics from related and unrelated sites suggests the possibility of fruit bats building social relationships among unrelated individuals and probably between species.

Abstract: The present study was conducted to understand the public attitudes and preferences of location and operation of environmentally suitable solid waste landfill sites in Dhanbad city, Jharkhand, India. The research methodology used for obtaining data includes extensive questionnaire (prepared using the reported literature) survey and interview of the population. Statistical analysis (Pearson residuals and chi-square test) was done to understand the relationships among the responses received from the surveyed people of the study area. Most of the respondents (90%) were in favour of construction of engineered landfill sites, but many (70%) were not willing to pay any extra charges for solid waste management related services. This study will help the municipal authorities to identify a mechanism to gain public acceptance of the selected landfill sites and adapt the approach presented here to similar locations elsewhere.

Keywords: Artificial seeds, encapsulation, recalcitrant, storage, temperature.
Abstract: Artificial seed technology is known to be the best alternative for short-term storage of plant germplasm in recalcitrant species. Aquilaria malaccensis, being a recalcitrant seeded tree, possesses seasonal and highly desiccation-sensitive seeds which lose viability with slight decrease in their moisture content, hence storage becomes a difficult task. The present study deals with short-term storage of A. malaccensis nodal buds through artificial seed technology. Nodal buds encapsulated with 2.5% sodium alginate and 100 mM calcium chloride and polymerized for 40 min were found suitable for artificial seed reparation. Maximum regeneration rate of 83.3% and 75.0% was observed from encapsulated nodal buds stored at 4°C and 23 ± 2°C respectively, for 10 days. Storage was possible for a period of 60 days at 4°C and 50 days at 23 ± 2°C with average regeneration rate of 8.3% and 16.7% respectively.

Keywords: Annual effective dose, laser fluorimetry, safe limits, uranium.
Abstract: Laser fluorimetry technique has been used to estimate uranium concentration in groundwater samples collected from 20 villages of Fazilka district, Punjab, India. The uranium concentration was found to vary from 4.32 to 83.99 μg l–1 at different locations with mean concentration of 26.51 μg l–1. Also, 24% of the drinking water samples exceeded the safe limits set by WHO, while 9% was above the limit set by AERB. Certain health risk factors like annual effective dose, excess cancer risk and lifetime average daily dose were also evaluated. The study also included uranium estimation in soil samples collected from the same villages using wavelength dispersive X-ray fluorescence technique. All the values were found to be well within the safe limits. Topography of the region seems to be the most likely reason for higher uranium concentration at some locations.

Subject: Alternative sources of soil organic amendments for sustaining soil health and crop productivity in India – impacts, potential availability, constraints and future strategies
Keywords: Climate change, crop productivity, organic amendments, soil health
Abstract: Among the several causes, critical low soil organic matter status is predominant for decline in soil health and consequent fall in crop productivity. Over the years, availability of traditional source of soil organic amendment, viz. cattle manure drastically declined due to various reasons (domestic uses as fuel and plastering of the kachha houses). The present study highlights that there are many alternative sources of soil organic amendments available in the country which have tremendous potential to improve soil organic matter status and crop productivity, and rejuvenate and enhance the dying total factor productivity of Indian soils. Data from various sources reveal that about 300 million tonnes of alternative sources of soil organic amendments are available in the country. This study highlights that the application of alternative sources of organic amendments directly or indirectly improves soil health by influencing many soil properties (physical and chemical) and enzyme activities (biological) that regulate nutrient dynamics in the soil. Consequent upon improvement in soil environment, the application of alternative sources of soil organic amendments alone or along with recommended dose of fertilizers registered significantly higher yield in different crops across different agro-climatic conditions of the country. Composting and vermicomposting are the best strategies to convert the biomass of available alternative sources of organic amendments to plant nutrient-rich products.

Abstract: Biological diversity provides the variety of life on the earth and agricultural diversity forms a part of it. Agricultural biodiversity refers to the variability among and between all forms of life relevant to food and agriculture. The Indian subcontinent is recognized as one of the important centres of origin of crop plants. There are around 811 plant species under cultivation in India with more than 900 wild relatives which are distributed over different biogeographic regions of the country. However, rapid genetic erosion of the species and surrounding ecosystem due to various factors is a big threat to this diversity. Biodiversity conservation is a global concern and all the member states of the Convention on Biological Diversity are taking measures to preserve both native and agricultural biodiversity. Biotechnological tools are proving valuable for effective and efficient conservation efforts of agricultural plant genetic resources. Among the various applications available, tissue culture, molecular marker technology, establishment of DNA banks and genotypic database for various crops and accessions have been delineated in this paper.

Keywords: Backfill deformation, ground subsidence, mining, stress redistribution.
Abstract: Backfilling is widely used in mining operations. Deformation of a large volume of backfill leads to rock movement and ground subsidence. This study analysed ground subsidence and backfill deformation, combined with ground subsidence monitoring and numerical simulation. The results showed that the ground subsidence trough was located at the centre of the hanging wall of the ore body. The maximum vertical displacement exceeded 2000 mm. Underground excavation and filling led to stress redistribution. The shear stress concentrated at the backfill boundary and contact zone of the backfill and surrounding rock. The shear stress distribution changed with the shape of the backfill. The corner of the backfill boundary was the key position of shear stress concentration. The Mohr’s circle showed the envelope line where cohesion of 500 kPa could meet the strength requirement in the shallow part of the backfill; in the deep part, the cohesion required was 1500 kPa. The deep part of the backfill therefore failed more easily than the shallow part.
