Keywords: Biomass turnover interactions, soil C sequestration, Western Ghats
Abstract: Soil carbon (C) forms a major pool in global C cycle and is estimated to store 1500–2000 Pg of carbon in the upper 1 m soil layer. Absolute amounts of C stored in the soil may vary considerably from one vegetation/land use type to another Atmospheric CO2 assimilated by plants is added to soil via roots and litter, undergoes decomposition with time, and only a fraction of the total carbon added to the soil is actually sequestered. In general, the soil C is higher in the surface layers and decreases with depth.

Abstract: Crude oil contamination causes a major environmental problem. The crude oil changes the microbial population present. in the soil, thereby affecting its properties. . The microbial community present in crude oil-contaminated soil has significant ecological importance. These microbes can be used as an effective tool for bioremediation. It has been well documented that soil contains the highest level of prokaryotic diversity than any other environment. One gram of soil can have more than 10 billion microorganisms comprising different species. Two approaches can be used for isolating bacterial DNA from the soil.

Keywords: Dried-up bore wells, Groundwater recharge wells
Abstract: Groundwater is the major source of drinking water and irrigation in many rural areas of India. In recent decades, groundwater abstraction using bore wells (also known as tube wells) from deeper aquifers increased manifold. Overexploitation of groundwater and its depletion over the years have resulted in drastic fall in groundwater levels and drying-up of existing wells in many areas. Construction of farm ponds, percolation tanks, earthen dams and minor water harvesting structures are some measures to enable storage and direct use of water and contribute to recharging and augmenting groundwater.

Abstract: At a global level, the Pacific white shrimp (Litopenaeus vannamei) is the main cultivable crustacean species. It currently accounts for a generous proportion of the total production of shrimp, as well as a large proportion of the animal protein supply to society. However, the presence of viruses and bacteria, the use of brood stocks based on phenotypic selections that do not guarantee the genetic traits of interest in shrimp development and feeding with diets other than fishmeal have impacted its growth, nutrition and increased its susceptibility to infectious diseases resulting in great mortality, which has reduced the total production

Subject: Fragilariopsis sp. Bloom causes yellowish-brown waters off Alappuzha, south-central Kerala coast
Keywords: Bloom, coastal upwelling, Fragilariopsis sp., mud bank, fisheries
Abstract: Mud banks (Chakara) of Kerala are calm coastal waters that form in several isolated stretches along the coast usually during the southwest monsoon (SWM) period (June-September).They are characterized by the damping of incident waves, generating localized calm sea environment conducive for fishing activities, while the high monsoon waves create hostile environment in the rest of the region. Here, we present the scientific basis of the yellwish-brown discoloration of water column that occurs off Alappuzha, Kerala annually during the peak and late SWM associated with coastal upwelling-mud bank event. The discoloured waters that occur off Alappuzha associated with these events are locally known as 'pola vellam', which is nothing but diatom blooms. In 2014, pola vellam was actually caused by the bloom of Fragilariopsis (=Fragilaria) sp; hereafter Fragilariopsis, which was widespread in the study region, even beyond the mud bank domain. This bloom feature is attributable to the nutrient enrichment associated with intense coastal upwelling that was dominant over a larger spatial extent in the study domain, including the mud bank. FlowCAM-based plankton data strongly support the above view, as the abundance , bivolume and biomass of Fragilariopsis had similar temporal trend both in the mud bank and non-mud bank regions. The general ecology and importance of Fragilariopsis bloom in the study domain, from the point of view of commercial fisheries, is also elaborated in this communication.

Subject: Population structure and reproductive biology of selected sciaenid species along the fishing grounds of Goa
Keywords: Fecundity, population, spawning ,Sciaenidae
Abstract: The present hypothesis on reproductive migration pattern between two species of sciaenids is based on the data collected with the help of the single-day commercial trawl with a fishing effort of 181 h along the fishing grounds of Goa, west coast of India. The observations on abundance revealed that between the two species (Johnius borneensis and Otolithes ruber) that formed bulk of the catch, a significant inverse trend in catch was observed. The pattern of migration based on the examination of female gonadal status suggested J. borneensis to be a continuous spawner and was evidenced by continuous occurrence of gravid and spent females and their juveniles. On the other hand, the rare occurrences of gravid females of O. ruber from the study area suggest that the species spawns away from the coast or might migrate to some potential spawning grounds. Further, an assessment of fecundity and the ova distribution pattern propounded higher fecundity in O. ruber compared to J. borneensis with multiple spawning in both the species.

Abstract: Inter-specific relationships of size and walking speed were examined in five species of predaceous ladybird beetles of aphid prey from different habitats. Lengths of legs, weight and volume of body, and walking speed varied significantly among the five species of different sizes that were reared on their preferred prey food in uniform growth conditions. The species are Menochilus sexmaculata, Coccinella transversalis, Anisolemnia dilatata, Micraspis discolor and Scymnus sp. Lengths of legs and body sizes showed similar growth rates across the five species (isometry), but the giant ladybird species showed significantly higher positive allometry in body volume (allometric coefficient, α = 6.66) and significantly lower negative allometry in walking speed relative to body weight (α =0.95) when compared to other species (α = 3.54).The unique response by the giant ladybird species in body form and speed may be attributed to its foraging habitat of perennial bamboo forests with large aggregations of non-winged apid food which seem to favour the evolution of higher body volume and slower speed for giant size when compared to species of smaller sizes which usually forage for short-lived aphid colonies in seasonal and annual habitats of crop plants and weeds. Evidently, size (weight and volume) and speed matter in the evolution of life history attributes of predaceous ladybird beetles.

Abstract: Corbett National Park (CNP), Uttarakhand, India is currently facing pressure of encroachments from human settlements around the buffer zone leading to increasing human and animal conflicts. In the present study, we have analysed the extent of land-use/land-cover (LULC) changes between 1976 and 2011 using medium-spatial-resolution satellite data in and around CNP. Future projections have also been generated using CA-Markov and agent-based SaarS model. The study highlights that unlike in the past decades, the projected LULC may undergo restricted growth in built-up area agriculture.

Abstract: Halophytes have superior capacity to withstand soil salinity and are appropriate resources to study the mechanism of salt tolerance which can be harnessed to develop crops to withstand salinity. In this communication,we report the effect of salinity (200 mM Nacl) and elevated carbon dioxide 9CO2) treatments in tandem, on select halophytes that have different photosyntheic pathways: c3 and c4.The plants were raised in ambient (380 ppm) and enriched (500 ppm) concentrations of CO2 using a mini-FACE facility. Total chlorophyll content, total soluble sugar concentration, lipid peroxidation level and electrolyte leakage were measured from fresh leaf samples collected at different time points. The results show a positive effect for elevated CO2 concentration on salt tolerance in both C3 and C4 plants, and indicate that halophytes may benefit from rising atmosheric CO2 concentration. The results also suggest that C4 halophytes may benefit from the rising atmospheric CO2 concentration than C3 halophytes.

Abstract: In this study, we assess quantitative soil loss in the Himalayan ecosystem of Uttarakhand, India using universal soil loss equation and geographic information system. The analysis shows that about 359, 000 (6.71%), 473, 000 (8.84 %) and 1, 750, 000 ha (32.72 %) area is under moderately severe (15-20 tonne ha-1 year-1), severe (20-40 tonne ha-1 year-1) and very severe (40-80 tonne ha-1 year-1) soil loss respectively. It clearly indicates that about 48.3 % area of the state is above the tolerance limit of 11.2 tonne ha-1 year-1 of soil loss. This explains the need to undertake appropriate soil and water conservation measures to mitigate the top soil loss in this fragile Himalayan ecosystem. Based on the degree of severity of soil loss, appropriate soil and water conservation measures need to be adopted on priority basis. The agriculture practices should be diversified with farm-forestry, agro-horticulture and /or agro-forestry to minimize soil loss in cultivated areas of the state. Such conservation programmes help mitigate accelerated soil erosion, restore the fragile ecosystems and generate employment opportunities for the needy.

Keywords: Freshwater content, sea surface salinity, seasonal variability, upper ocean region
Abstract: Any change in precipitation, evaporation and river discharge, by virtue of its impact on the distribution of ocean salinity, leaves its inevitable signature on the freshwater content (FWC) in the oceans. In this study, synergistic use of satellite data and numerical ocean circulation model is explored to examine the seasonality of FWC of the upper 30 m water column of the Bay of Bengal (BoB). For this purpose, first the sea surface salinity (SSS) from Aquarius is assimilated into a model of the Indian Ocean. Strength of assimilation is judged by comparing simulated SSS with satellite and Agro datasets. An overall improvement of 39% is observed in SSS over free run of the model without data assimilation. Next, the focus is shifted to the spatial and temporal variability of fwc of the upper 30 m of BoB in relation to the different components of freshwater forcing. A delay of three months in the peak of FWC is observed with respect to the peak of net freshwater influx for BoB as a whole. However, the nature of the response of FWC to the total freshwater input forcing in the major river-dominated regions of BoB is different from that for the whole BoB. The relative role of river influx in controlling FWC in these regions is well brought out in the study. For the Ganga-Brahmaputra region, river run-off is observed to be a crucial parameter in regulating FWC, whereas for both Irrawaddy river region and central BoB, precipitation dominates the response. The response of salinity in the uppermost part of the northern BoB to the total freshwater input is much more rapid than in the other regions.

Abstract: In this study, Chromobacterium violaceum was subjected to sonic (100-2000 Hz) stimulation. Sound waves of300 Hz frequency promoted bulk production of the quorum-regulated pigment,violacein. Whole transcriptome analysis indicated that a total of 342 genes (i. e.4.63 % of the whole genome )were significantly upregulated in the sonic stimulated culture. Enhanced violacein production in the sound-stimulated culture seems to have stemmed from enhanced expression of the genes involved in pentose phosphate pathway,resulting in an increased availability of erythrose-4-phosphate to be used in the synthesis of tryptophan-the precusrsor of violacein synthesis. This study is a good demonstration of the ability of sound waves to alter bacterial metabolism.

Subject: Expression profiles of key genes involved in rice gall midge interactions reveal diversity in resistance pathways.
Keywords: HR+ type resistance, HR-type resistance, HR, ROS, SAR
Abstract: Resistance against the Asian rice gall midge,Orseolia oryzae (Wood-Mason), is conferred by any one of the 11 major genes identified so far. Resistance conferred by these genes mayor may not involve a hypersensitive reaction (HR). Three of these gall midge resistance genes have been already, cloned. In this study, expression of 20 key genes, identified based on our earlier studies, in 12 rice genotypes was profiled through quantitative real time (RT)-PCR at two time points. Results highlighted diversity in resistance pathways either involving reactive oxygen species (ROS)-hypersensitive reaction (HR) salicylic acid-mediated systemic acquired resistance or strong suppression of ROS-HR at initial stage itself. Some of the susceptible test genotypes derived from crosses between gall midge resistant and susceptible parents expressed trace activity of these genes even during compatible interaction.

Subject: Modelling of climate-induced groundwater recharge for assessing carbon emission from groundwater irrigation
Keywords: Climate change, carbon emission, ground-water modelling, groundwater recharge, HYDRUS, MODFLOW
Abstract: In this study impact of climate change on ground-water recharge is investigated and the carbon emission from groundwater irrigation is assessed under projected climate change scenarios for Karnal district of Haryana state in India. HYDRUS-1D and MODFLOW models were used to simulate the climate the change impacts on groundwater recharge for different projected climate change scenarios. Simulation results showed that groundwater recharge would increase marginally by 2030 over the baseline year of 2008 under the scenario based on ARIMA predictions, which considered the effect of all climate parameters. However, under the scenarios, which considered only rise in temperature, groundwater recharge would decrease by 0.07-0.22 m. Rise in temperature by 3.5°C. and 4.3°C along with 9 % and 16% increase in rainfall over the base year would increase the recharge by 0.09 m and 0.14 m respectively. The study also revealed that the effect of climate change on cumulative recharge would be more in sugarcane fields than in rice fields. Carbon emission of groundwater irrigation under the scenarios based on rise in temperature only would increase by a minimum of 12 kg Co2/ha in pearl millet crop by the year 203 to a maximum of 3250 kg co2/ha for sugarcane crop by the end of this century. Estimated total carbon emission in 2030 would be 345, 857 metric tonne from groundwater irrigation in Karnal district which is 87, 474 metric tonne more than the baseline emission.
