Groundwater Ecology

In recent times, ecohydrology and hydroecology are making a mark on theenvironmental agenda, as evidenced by the proliferation of these terms in theacademic literature. There is an increasing recognition that groundwater is essentialto many ecological communities. Surface ecological processes (such asevapotranspiration) significantly impact hydrological responses and relatedhydrochemical function. Thus, the relation of groundwater hydrology to patternsand processes in ecology is a ‘two-way street’ where understanding the feedback ofone to the other serves as a powerful lens through which to evaluate and explainthe functioning of natural ecosystems. Influxes of groundwater to lakes, rivers, andwetlands can change whole-system physico-chemical properties such astemperature and salinity, while also providing more subtle influences onmicroenvironments and their ecological processes. The recognition of thesignificance and power of this tandem has not always been followed with effectiveinterdisciplinary science. The ecological, hydrological, and physico-chemical linksbetween groundwater, surface water and associated ecosystems are seldom fullyunderstood even though true characterization and wise management will require amultidisciplinary approach. This means biologists need to understand theimportance of magnitude and timing of groundwater flows for their system, whichrequires the skills of hydrogeologists to achieve. Hydrogeologists, in turn, mustunderstand how and why groundwater influences ecological processes so that theirexpertise is brought to bear at a scale commensurate to the ecological researchquestion. In this paper therefore, an overview of general concepts, research effortsand future perspectives are presented. More importantly, the paper asserts that it isnot simply the integration of hydrology and ecology that will determine the futureprospects for ecohydrology/hydroecology, but the way in which this integrativescience is conducted.

Palmyrah palm has great economic potential and every part of the palm is useful in one way or the other.The palm is found growing widely in southern states of India. The palmyrah products like tender fruit endosperm (nungu), neera, jaggery and tuber flour are not commercialised as the value addition in palmyrah is not standardised. Even though palmyrah is an economically important palm, it has not received proper attention from the agricultural research workers, probably on account of the fact that it is very slow growing palm found mostly in the wild state. In this context knowing of physico chemical properties and development of value added products and popularizing the same is essential.

Dicationic Ionic Liquids

A series of dicationic ionic liquids (ILs) including [C 4 (MIM) 2 ][PF 6 ] 2 , [C 5 (MIM) 2 ][PF 6 ] 2 , [C 6 (MIM) 2 ][PF 6 ] 2 and [C 4 (PYR) 2 ][PF 6 ] 2 were synthesized. Their thermal stability and melting points were analysed. It was found that dicationic ILs presented important implications in the design of homogeneous and heterogeneous system with water. A homogeneous system of dicationic ILs with water could be formed at a relatively high temperature and then a heterogeneous system was formed when the solution was cooled to a low temperature. The ILs recovered by altering the temperature were obtained in high percentage yields of [C 4 (MIM) 2 ][PF 6 ] 2 (97.6%), [C 5 (MIM) 2 ][PF 6 ] 2 (97.3%), [C 6 (MIM) 2 ][PF 6 ] 2 (98.0%) and [C 4 (PYR) 2 ][PF 6 ] 2 (94.2%). On the other hand, [C 4 (MIM) 2 ][PF 6 ] 2 and [C 5 (MIM) 2 ][PF 6 ] 2 exhibited good solubility in acetonitrile and acetone. A homogeneous system could be achieved with imidazolium-based ILs with a relatively low amount of water and acetonitrile at room temperature. All of the properties of dicationic ILs have a strong correlation with the nature of dications, the linkage chain and the symmetry of dications. Dicationic ILs may provide a new opportunity for some specific applications in order to enable the effective separation and isolation of products.

This work focuses on analyzing of physico-chemical properties of sediment affected by frequent floods along the eastern shore of the Bandama River in the department of Niakaramadougou. Sampling was from 4 excavated graves at two positions of studied area, one near the stream and the other one far away from the stream.. Samples collected were analyzed, including texture with granulometric analysis made by the Robinson pipette, and standard sediment analysis methods for measuring organic carbon (OC), nitrogen (N), and other chemical properties including pH, organic matter (OM), and C/N ratio. Statistical analyses were carried out to assess the differences between the physico-chemical parameters at different sampling areas. Differences are significant when comparing areas that are highly affected by floods and areas that are less affected by floods, especially for concentrations of OM, OC and nitrogen. Results show that successive floods are influencing directly the dynamic of physico-chemical properties of the sediments along the shore.

A pot experiment was conducted in the Net house of Soil Science Division of Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during rabi season, 2017-2018 in Tista Meander Floodplain Soils (AEZ-3). The objectives were to evaluate the effect of boron on the yield of wheat, estimate boron use efficiency and to find out suitable variety for maximizing the yield. The experiment was designed in Completely Randomized Design (CRD) with three replications. Three varieties of wheat (BARI Gom-28, BARI Gom-29 and BARI Gom-30) with 5 levels of boron (0, 0.5, 1.0, 1.5 and 2 kg ha-1) along with a blanket dose N120P30K90S15Zn3Mg6 kg ha-1 were used in the study. All the three varieties performed well with application of 1.5 kg B ha-1 as compared to the other B treatments. However, the highest yield (39.2 g pot-1) was obtained with BARI Gom-30 variety receiving B at 1.5 kg ha-1. Bangladesh J. Agril. Res. 44(2): 303-310, June 2019

Effect of consuming solely poultry-by-products by grower pigs, instead of conventional feeds was the focus of this study. Thirty–six Large White male pigs of 6 weeks 5.7 – 7.5kg were fed Boiled Dead Birds (BDB) (T3), Boiled Hatchery Waste BHW (T2) and conventional pig food PKC (T1). Thus, there were three treatments with 12 pigs per treatment. The pigs were reared for 10 weeks over which the chemical composition, performance and digestibility studies, carcass and organ function, serum and haematological status, and physico – chemical analysis and palatability were evaluated. The study was arranged as a completely randomized design. Daily weight gain, daily feed intake and body weight gain had highest (P<0.05) values of 107.45g. 105.31g and 4513.00g inT1 compared to T2 (37.52g, 63.39g and 1580.00g) and T3 (60.00g, 63.30g and 2520.00g) respectively. Pigs on T3 performed best in physico – chemical evaluation having the lowest (P<0.05) for thermal and cold shortening, cooking loss and thaw rigor but highest (P<0.05) values for water holding capacity than for T1 and T2. Lymphocyte values and white blood cell were best for T3 while T1 had highest in monophils. The T3 had lowest significant cholesterol value (106.80 mg/dL), than T2 (336.76 mg/dL) and T1 (123.88 mg/dL) while T1 did best (P<0.05) in glucose content (84.92 mg/dL), compared to T2 (60.22 md/dL) and T1 (66.63 mg/dL). The T1 had the highest palatability scores (P<0.05) for palatability status than T2 and T3. T1 performed bestin palatability scores, performance evaluation and carcass and organ characteristics, while T2 and T3 led to higher physico – chemical properties, serum and haematological parameters, which had positive significant effect on the health status of the pigs.

The effects of passive- and active-modified atmosphere packaging (passive- and active-MAP) were investigated on the physio-chemical and quality attributes of fresh in-hull pistachios stored at 4 ± 1 °C and 90 ± 5% R.H. Fresh pistachios were packaged under each of the following gas combinations: active-MAP1 (AMA1) (5% O2 + 5% CO2), AMA2 (5% O2 + 25% CO2), AMA3 (5% O2 + 45% CO2), AMA4 (2.5% O2 + 5% CO2), AMA5 (2.5% O2 + 25% CO2), and AMA6 (2.5% O2 + 45% CO2), all balanced with N2, as well as passive-MAP (PMA) with ambient air (21% O2 + 0.03% CO2 + 78% N2). Changes in quality parameters were evaluated after 0, 15, 30 and 45 days of storage. Results demonstrated that AMA6 and PMA had significantly lower (7.96 Log CFU g−1) and higher (9.81 Log CFU g−1) aerobic mesophilic bacteria counts than the other treatments. However, the AMA6 treatment decreased, kernel chlorophyll and carotenoid content, hull antioxidant capacity, and anthocyanin content. The PMA treatment produced a significant weight loss, 0.18%, relative to the other treatments. The active-MAP treatments were more effective than the passive-MAP in decreasing weight loss, microbial counts, kernel total chlorophyll (Kernel TCL), and kernel carotenoid content (Kernel CAC). The postharvest quality of fresh in-hull pistachios was maintained best by the AMA3 (5% O2 + 45% CO2 + 50% N2) treatment.
