Growth, development and nutritional indices of tobacco caterpillar, Spodoptera litura (F) raised on bell pepper plants grown under elevated CO2 and temperature conditions


 The experiment was conducted at experimental farm situated at 30◦5’N latitude and about 77◦11’E longitudes, an elevation of 1260 m above mean sea level of Department of Environmental Science, Dr YS Parmar University of Horticulture and Forestry Nauni, Solan, Himachal Pradesh during 2014 and 2015, to study the effect of elevated CO2 (eCO2) and elevated temperature (eT) on growth, development and nutritional indices of Spodopteralitura on bell pepper plant. Feeding trials with foliage feeding insect S. litura was conducted using foliage of bell pepper plants grown under four concentrations of CO2 and temperature, viz. three Open Top Chambers, (T1: OTC eCO2 550±10 ppm; T2: OTC with elevated temperature 1°C higher and eCO2 550±10 ppm; T3: OTC with ambient temperature and CO2 and T4: natural ambient air and temperature in open. Biochemical analysis of foliage revealed that plants grown under elevated CO2 had lower nitrogen. The larvae fed on eCO2 as well as eCO2 and temperature foliage exhibited greater consumption compared to the larvae fed on foliage under ambient CO2. Larval duration also increased by two days. The eCO2 and eCO2 and temperature foliage was more digestible with higher values of approximate digestibility. The relative consumption rate increased whereas the efficiency parameters, viz. efficiency of conversion of ingested food (ECI), efficiency of conversion of digested food (ECD), and relative growth rate (RGR) decreased in eCO2 and eCO2 and temperature. The consumption and weight gain of the larvae were negatively and significantly influenced by leaf nitrogen.

Spatial analysis of natural reserve fund of the Zakarpatska Oblast


 
 
 The article brings light to the study of the nature reserve fund (NRF) of Zakarpatska oblast as a component of the national heritage of the country. Representativeness is considered to be one of the main principles of spatial formation of the NRF object network. Therefore, to determine the current state and ensure further effective development of the region’s nature reserve fund, it is necessary to analyze its territorial and internal structural indicators. The purpose of the study is to analyze the current status of the region’s nature reserve fund with the reference to the possibility of introduction of the further new management practices. The article is based on information and statistical materials, the provisions of regional programs for the formation of the ecological network and environmental legislation of Ukraine. To solve the assigned tasks, there has been done a comprehensive analysis of statistical reporting data and materials of the NRF Register in Zakarpatska oblast of the Department of Ecology of Natural Resources of Zakarpattia Regional State Administration within the period of 2019, and reporting documents of environmental institutions for the same period. The considered indicator is the territorial distribution of nature reserve areas and region areas by administrative districts (before the formation and implementation of changes to the administrative-territorial structure of the Zakarpatska oblast), which is presented in the form of the division into four groups. The spatial distribution of the territory and the NFR objects do not sufficiently meet the criteria of local representativeness, so their spatial structure needs significant improvement, be specific – the creation of nature reserves, especially in the lowlands of the region. The average density of nature protection objects in the region (36 units / 1000 km2) is almost three times higher than the corresponding indicator in the neighboring Lviv region. The average value of the reserve factor in the region makes 14.17 %. It has been found that the reserve ratio demonstrates geographically the largest disproportion in Zakarpatska oblast. It is the highest indicator in turns of administrative entities in the districts of Mizhhiria, Velyky Bereznyi and Rakhiv. The lowest one is in Svaliava and Berehove districts, respectively. In addition, the reserve ratio compared to the national average indicator and in other European countries has been carried out. The quality of the nature reserve network is determined by the insularity coefficient, which indicates the size of the NRF objects and their stability. Further expansion of the network of nature protection objects in Zakarpatska oblast is possible due to the creation of Latorytsa, Shaian and Uzhok landscape parks. A big assumption can be made that by 2020 it will be possible to create new and expand existing areas of NRF in the region up to 100–120 thousand hectares, which will increase the protected area up to 20–22 %. The key issues of nature reserves to be developed in Zakarpatska oblast are primarily related to the imperfection of the management system. To handle this problem, there is an urgent need to develop a strategy, which will envisage the perception of the NRF as a holistic anthropogenic and natural unit in order to put into practice the environmental, scientific, educational and recreational functions.

A Note about ʻFoulgo’ Salt Processing and its Role in the Livelihood of Dwelling People in Gabal Marra

The aim of this note was to outline the processing of a table-salt, locally known as “Foulgo salt” in Gabal Marra area, and highlighting its socio-economic impact on the livelihood of the mountain dwellers. Salt samples were procured from a local producer and were chemically analyzed in the laboratory of the Soil and Environmental Sciences Department, Faculty of Agriculture, University of Khartoum in August 2020. The preparation steps include: impregnation of soil by salt in the farm, collection and percolation of the soil and evaporation of the solute at home and yield of the salt. The salt is grey to pale brown in colour and has small crystals and readily dissolves in water. The salt is composed of 78.9% NaCl, 0.5 % Ca, 0.78 % Mg and traces of K. Its Ec is 19.97dS/m and TDS of 1280.8 ppm. The salt is used for human consumption and for various purposes. It is sold to get income and historically it was used for trade both as commodity and exchange currency. The salt is still produced at small scale, and its production is anticipated to continue for some time in response to the prevailing local demand

Anaerobic Decolorization of Sulfonated Azo Dyes by Sulfate Reducing Bacteria

Aim: The present study was done to find out ability of sulfate reducing bacteria to reduce sulfonated azo dyes found in the textile effluent.
 Study Design: Isolate Sulfate reducing bacterial strains from dye contaminated soil samples, inoculate and incubate dye supplemented media under static anaerobic condition and measure the decolorization using UV-VIS spectrophotometer.
 Place and Duration of Study: The samples were collected from Travancore textiles Nemom, Thiruvananthapuram, Kerala, India. Laboratory analysis were performed at Department of Environmental Sciences, University of Kerala, Thiruvananthapuram, India. The study was done for a period of six months.
 Methodology: The isolated sulfate reducing bacterial (SRB) strains were screened to test the tolerance to selected sulfonated azo dye Direct blue 71. The decolorization assay was done in Postgate media and an aliquot of samples (3mL) were withdrawn periodically, centrifuged at 10,000rpm for 15min. The supernatant was used to assay azo dye reduction by measuring residual absorption at the wavelength 594 nm of the Direct Blue 71. Results were compared with the uninoculated control. The optimization of physicochemical conditions for effective decolorization of the selected bacterial strains was studied at different environmental conditions (pH, temperature, concentration and added co-substrates such as sodium acetate, lactate and mannitol). The biodegradation of sulfonated azo dye was assessed by characterizing the metabolites formed after degradation by Fourier Transform Infrared Spectroscopy (FT-IR). FT-IR analysis revealed only decolorization had occurred without degradation of the dye during the short incubation period of one week.
 Conclusion: Degradation of azo dyes and other recalcitrant compounds by obligate anaerobes such as sulfate reducing bacteria is a slow process. Hence, extension of incubation period is necessary for the effective and complete degradation of the dye by SRB.

Such assessment of the water quality in the urban area of Mulyanka, Danilikha, Yegoshikha and Iva rivers catchments are presented in this study. The analysis is given for the background and mouth sections. The data of river’s water chemical composition was used for periods 2009-2010 and 2015-2018. A comparative analysis of water quality in terms of pollution indices is given.

The assessment of the environmental impact of the waste sludge and hazardous chemicals in the arroyo of Yasynov city of Kamyanske

The main structures of tailings and sludge facilities are tailings and sludge storage facilities, tailings and sludge hydraulic transportation facilities and circulating water supply facilities. Therefore, the assessment of the environmental impact of the sludge storage of waste and hazardous chemicals in the Yasinova arroyo of the city of Kamyanske is an urgent task for scientists and workers of the ore-processing industrial enterprises. The aim of the work is to assess the impact on the environment of the sludge storage of waste and hazardous chemicals in the Yasinova arroyo of the city of Kamyanske. The object of the study is the process of environmental pollution due to the activity of sludge from waste and hazardous chemicals in the Yasinova arroyo of the city of Kamyanske. The research subject is the reduction of the level of environmental pollution during the activity of the sludge storage’s waste and hazardous chemicals in the Yasinova arroyo of the city of Kamyanske. The initial data of the laboratory analysis of water samples were provided by the laboratory of OJSC Dniproazot. Regulatory and technical documentation is provided by the Department of Environmental Protection of the Department of Ecology and Natural Resources of the city of Kamyanske. The ecological situation in Kamyanske has long been characterized as a crisis. A significant excess of geochemical parameters of some elements in soils was recorded. Particular attention should be paid to the content of Ce and REE in the polymineral substance of tailings. Exceedances of the maximum concentration limits of Ni and Cu in the Konoplyanka River, which flows in the immediate vicinity of the tailings; which suggests an assumption that there is a migration of these elements from the tailings with groundwater and their accumulation near the river.

Modelling ultrafine particle number concentrations at address resolution in Denmark from 1979-2018 – Part 1: Regional and urban scale modelling and evaluation

The integrated model system DEHM/UBM/AirGIS, developed at Aarhus University, Department of Environmental Science, has been extended with the dynamic aerosol module M7 to account for particle number concentrations of particles with diameters below 1 μm in the atmosphere. The aim of this development is to quantify the spatial and temporal distribution of particle number concentration across Denmark and evaluate the results with available measurements. This article presents model results for particle number concentrations from the regional scale model DEHM and the urban scale model UBM, for comparison with measurements of particle number concentrations from European and Danish measurement stations. The deterministic modelling of particle number concentration has been vitiated by the lack of consistency between emission inventories, and the evaluation of the models is challenged by the lack of consistent long-term measurements data. The performance evaluation of the DEHM and UBM models shows that both models overestimate the level of the particle number concentrations at all stations, however, the results for the correlation coefficients are 0.86 for DEHM and in the range from 0.86 to 0.87, for UBM, for annual mean particle number concentrations at Danish measurement stations. We conclude that the inclusion of particle number concentration in DEHM and UBM shows some capability of reproducing observed patterns, when comparing the results of the models with available measurements, but that there is also room for improvement, especially with respect to the emission inventories and preprocessing of emissions and to the treatment of volatile organic compounds based on natural emissions during summer time.

Relationship between Air Pollution and Hospital Admissions for Chronic Obstructive Pulmonary Disease in Changchun, China: A Season-Stratified Case-Cross Study.

Background This study aimed to explore the relationship between air pollution and hospital admissions for COPD in Changchun, a northeast city of China, in different seasons. Methods The data on a total of 1,733 hospitalized patients living in Changchun with acute exacerbation of COPD from September 2013 to April 2018 were collected from a comprehensive 3A hospital of Changchun. Daily average concentrations of PM2.5, PM10, SO2, NO2, CO, and O3 were collected from the Department of Ecology and Environment of Jilin Province. The conditional logistic regression model was adopted to analyze the effect of air pollutant concentration on the number of hospitalized patients with COPD in different seasons. Results The maximum OR value for most air pollutants emitted in spring was on lag day 4, in summer and autumn on lag day 3, and in winter on lag day 2. In spring, SO2 and NO2 were entered into the regression equation, and the OR (95%CI) was 0.992 (0.986–0.998) and 1.009 (1.002–1.017); in autumn, PM2.5, PM10, and SO2 were entered into the regression equation, and the OR (95%CI) was 1.005 (1.000–1.011), 0.995 (0.991–1.000), and 1.006 (1.001–1.011), respectively; and in winter, PM2.5 and PM10 were entered into the regression equation, and the OR (95%CI) was 1.008 (1.002–1.015) and 0.994 (0.988–0.999), respectively. Conclusion The relationship between air pollution and hospital admission for COPD in Northeast China varies with different seasons. In spring, NO2 is likely to be the major risk factor for hospital admissions for COPD; in autumn, PM2.5 and SO2 are the major risk factors; and in winter, PM2.5 is the major risk factor.

New eodermapteran earwigs (Dermaptera) from the Middle Jurassic Jiulongshan Formation of China

A new genus of eodermapteran earwigs, Aglyptoderma gen. nov., is described from the Middle Jurassic Jiulongshan Formation of Inner Mongolia, China. It comprises two new species—Aglyptoderma elongatum gen. et sp. nov. and Aglyptoderma cylindratum gen. et sp. nov. The genus belongs to the family Semenoviolidae, hitherto known only from the Late Jurassic of Kazakhstan. However, owing to significant differences in the form of the head, pronotum, tegmina and tarsomeres, the new genus is classified within a separate subfamily, Aglyptodermatinae subfam. nov. The features of the new genus are discussed in the context of existing hypotheses regarding post-Jurassic character-state transitions in the postabdomen of female Dermaptera. In particular, reduction of the cerci and internalization of the ovipositor across Archidermaptera, Eodermaptera, and Neodermaptera may relate to the variety of maternal care behaviours seen among earwigs.

PROFESSOR VOLODYMYR KUCHERYAVYI SCIENTIFIC SCHOOL OF URBOECOLOGY, PHYTOMELIORATION AND LANDSCAPE ARCHITECTURE

Introduction. The theoretical foundations of the new ecological disciplines "Urban Ecology" and "Phytomeliora-tion" were laid in the mid-80's and 90's of the last century at the Department of Ecology and Landscape Architecture of the Ukrainian National Forestry University, which at that time was headed by Lviv scientist Volodymyr Kucheryavyi famous by his monographs “Green Zone of the City” (Kyiv: Naukova Dumka, 1981) and “Natural Environment of the City” (Lviv: Higher School, 1984).Purpose and methods. The methodological basis of urban ecological research is the ecological-comparative method, which involves gradation ordination with the allocation of four ecological and phytocenotic zones on the territory of cities into the study of the urban ecosystem (suburban forests - city parks – public gardens - street plantings) (V. Kucheryavyi, P. Hnativ, M. Kurnytska, N. Siroochenko, N. Stepanyak, K. Myronchuk, T. Pushkaryova, Yu. Kozak) This approach is used in dissertation research not only by graduate students and applicants of the Department of Ecology and Landscape Architecture of UNFU, but also young scientists of Kyiv, Lutsk and Chernivtsi.Results and discussion. Taking into account the growth of the "recreational boom" among urban residents in the 80's and 90's, scientific researches of park and forest park phytocenoses are developed (V. Kucheryavyi, A. Zhyrnov, Yu. Khrystuk, R. Danylyk, V. Kramarets, N. Lukyanchuk, O. Kaspruk, R. Dudyn, N. Imshanetska, N. Kovalchuk, S. Marutyak, O. Oleynyuk). During this period, visual methods of diagnosing of urban ecosystems state are widely used, which confirm the feasibility of using of ecowedge ordination. The influence of complex urbogenic gradients of the environment on the adaptation processes of living organisms and their significance for the evaluation of the results of woody plants introduction into the urbogenic environment was determined (V. Kucheryavyi, M. Kurnytska, O. Kaspruk, O. Gorbenko, M. Les, V.S. Kucheryavyi, T. Shuplat, N. Gotsiy). Electro-physiological methods of impedance and polar-ization capacity measuring, fluorescence of plastid pigments, temperature gradients of the environment are used for establishing the level of plant viability (V. Kucheryavyi, H. Krynytskyi, V. Mokryi, A. Kuzyk, M. Hozdog, S. Hridzhuk, Yu. Pankivskyi, V. Kucheryavyi, T. Shuplat). Investigations of the phytogenic field of vegetation begin, its role in the formation of the continuum in conditions of urbogenic and manmade devastation is determined (V. Kucheryavyi, V. Popovych, T. Levus, T. Shuplat). The formation of a scientific school on urban ecology and phytomelioration is ensured by the three generations of scientists succession. A significant number of scientists have passed the scientific path from post-graduate student in the 80's - 90's to the candidate or doctor of sciences (P. Hnativ, V. Mokryi, V. Mazepa, S. Myklush, M. Nazaruk, Ya. Henyk, V. Popovych).Conclusions. The authoritative leader of the scientific school on urban ecology, phytomelioration and landscape architecture is Professor Volodymyr Kucheryavyi, who has supervised four doctors and 22 candidates of science. During the years of his scientific activity he published about 300 scientific articles, more than 30 monographs and textbooks. Heading the scientific and methodological commission of the Ministry of Education and Science of Ukraine on environmental education in the 80's and 90's, he started training specialists in "applied ecology" in Ukraine. Thanks to the initia-tive of prof. V. Kucheryavyi scientists of the Scientific School of Urban Ecology, Phytomelioration and Landscape Architecture took an active part in many international projects (V. Kucheryavyi, Ya. Henyk, L. Kalahurka, M. Chernyavskyi, O. Oleynyuk, L. Parkhuts, Z. Sheremeta, S. Melnychuk, V. Popovych, T. Shuplat, M. Fitak, V.S. Kucheryavyi). The scientists worked closely with research teams from Germany, Austria, Belgium, Poland, Slovakia, the Czech Republic, and Norway. Scientific research on urban ecology, phytomelioration and landscape architecture, which began in the 1980s, continues thanks to the succession of scientific generations.

IMPROVEMENT OF THE HYDROECOLOGICAL CONDITION OF TEREMNIVSKY PONDS

The article is devoted to the assessment of the current hydroecological condition of Teremnivsky ponds, the factors influencing it, the connection with the hydroecological condition of the Sapalaivka river. The history of research of hydroecological condition of Teremnivsky ponds, features of physical and geographical conditions of locality and anthropogenic influence on ecosystem of ponds are analyzed. The reservoirs are located in the Teremnivskyi district, where low-rise private buildings and a few of industrial enterprises predominate. Ponds and their shores are a place of rest and recreation of local population. It has swimming and sunbathing beaches, shopping and catering facilities. The shores of the ponds are currently insufficiently landscaped and have poor sanitation. The reservoir is a typical floodplain pond in the valley of the river Sapalaivka. Built in the 60's. XX century Recently, the ecological and sanitary condition of ponds has deteriorated, which makes it difficult to use them for recreational purposes. This is largely due to the poor ecological condition of the Sapalaivka river. Teremnivsky ponds in the summer are characterized by eutrophication - the enrichment of reservoirs with nutrients, which is accompanied by increased productivity of the reservoir. Much of the surface of the reservoir is covered with a film of duckweed and other algae. Poor sanitation of the reservoir banks also contributes to eutrophication. Shores are not removed from fallen leaves, household waste. It all gets into the stakes and pollutes them. It is determined that the hydroecological condition of Teremnivsky ponds is most affected by: chemical composition of water, microbiological water pollution, eutrophication of the reservoir in summer, sanitary condition of the reservoir banks, ecological condition of the Sapalaivka river, where the reservoir was created. It is established that the content of certain chemical pollutants in the water of Teremnivsky ponds exceeds their maximum permissible concentration in reservoirs for fishery use. Such water pollution is caused by the ingress of surface runoff from the city, sewage from latrine pits and garbage from the population. Thus, the hydroecological and sanitary condition of Teremnivsky ponds today is unsatisfactory and requires optimization. Previously implemented measures of local environmental programs are analyzed. In 2012-17, on the initiative of the Department of Ecology of the Lutsk City Council, measures were taken to improve the hydroecological condition of the Sapalaivka River. At present, a significant amount of urgent work has been done, and the project is still far from complete. In 2013-2014, landscaping with elements of revitalization of the valley of the Sapalaivka River was carried out. A set of measures for the completion and successful implementation of the project to improve the hydro-ecological condition of Teremnivsky ponds is proposed. It includes: cleaning and tidying up the water area and the surrounding area; technical measures (treatment of surface runoff from the city and prevention of contaminated wastewater; bioremediation measures (treatment of ponds from pollutants already in the water, improving the sanitary condition of water and combating eutrophication of the reservoir).
 Key words: ponds, hydroecological condition of ponds, factors determining the hydroecological condition of ponds, measures to improve the hydroecological condition of ponds.

Monitoring Ocean Acidification within State Borders: Lessons from Washington State (USA)

The Washington State Department of Ecology conducted a large-scale ocean acidification (OA) study in greater Puget Sound to: (1) produce a marine carbon dioxide (CO2) system dataset capable of distinguishing between long-term anthropogenic changes and natural variability, (2) characterize how rivers and freshwater drive OA conditions in the region, and (3) understand the relative influence of cumulative anthropogenic forcing on regional OA conditions. Marine CO2 system data were collected monthly at 20 stations between October 2018 and February 2020. While additional data are still needed, the climate-level data collected thus far have uncovered novel insights into spatiotemporal distributions of and variability in the regional marine CO2 system, especially at low salinities in shallow, river-forced shelf regions. The data provide a strong foundation with which to continue monitoring OA conditions across the region. More importantly, this work represents the first successful long-term OA monitoring program undertaken at the state-level by a regulatory agency. Therefore, we offer the work described herein as a blueprint to help state and local scientists and environmental and natural resource managers develop, implement, and conduct long-term OA monitoring programs and studies in their own contexts and jurisdictions.

Washington methanol plant canceled

Northwest Innovation Works has shelved plans to build a methanol complex in Kalama, Washington, after the state’s Department of Ecology denied permits for the massive facility. NW Innovation planned to spend about $2 billion to build 3.6 million metric tons per year of methanol capacity. The output would have been shipped to China for use as a chemical feedstock. The company, which proposed the project in 2014, had been considering other facilities in the region as well. The Port of Kalama says Gov. Jay Inslee had initially supported the project but “turned on us when he ran for president.”
