  • Influence of irrigation on the Sunn pest Eurygaster integriceps Put.
           (Insecta: Heteroptera) in the Central Forest-Steppe of Ukraine

    • Authors: Fedir Melnichuk; Svitlana Alekseeva, Oleksandra Hordiienko, Oleksii Nychyporuk, Andrii Borysenko
      Abstract: The aim of the research is to establish the influence of watering on the phenological and biological features of winter wheat pests development, in particular Sunn pests. Trials were conducted on winter wheat crops under sprinkler irrigation in 2015-2020 in conditions of the Central Forest-Steppe of Ukraine. The size of the experimental plots in the field experiments was 50 m2 (10.4x4.8 m) at the 4 times replication. The allocation of plots was randomized. The average numbers of Sunn pest nymphs in 2015-2020 were 0.7-2.7 exemplars/m² on non-irrigated winter wheat crops and 0.8-3.8 exemplars/m² on irrigated. The share of the factor “presence of irrigation” that impacts on the number of Sunn pests reaches 80.2%. The sums of degree-days necessary for the beginning of different development stages of this phytophagous were calculated. The stage of the revival of Sunn pest nymphs began in mid-May – the first decade of June, which coincided with the phases of development of winter wheat: the end of flowering – soft dough ripening of the grain. The sum of degree-days required for the beginning of this stage was 177.8-233.8°C without irrigation, while in sprinkler irrigation conditions – 275.5-349.1°C. For the beginning of the transformation of the fifth instar nymphs into adults, the required sum of degree-days was 410.5-481.5°C on the non-irrigated crops and 545.7-630.4°C – under conditions of irrigation. Clarifying the sum of degree-days required for different stages of Sunn pest development will allow for predicting the terms of protective measures against this pest in the field conditions under irrigation.

      Abstract: Karachi is the major financial hub of Pakistan. The urban sprawl generates many sub financial hubs as well e.g. Saddar which is consider as CBD of metropolitan, specifically area along I.I. Chundrigar road is almost have offices and business set-up. The similar pattern has been emerged in many other places e.g. Shahrah-e-Faisal and Tariq road. Along all three major roads mixed-used development particularly commercialization has taken place prominently and these sectors emerged as main business Centre. The present study was aimed to assess the Land-Use/Land Cover (LU/LC), green cover and air quality index analysis through object based analysis on very high-resolution satellite imagery at Shahrah-e-Faisal. The obtained results showed that the combine three activities such as Shopping, Business and Trade (SBT), Social, Institutional and Infrastructure related activities (SII), and travel or movement (ToM) were occupied on 51.34% of land. The residential activities also make an attractive volume of proportion was up to 47.11%. Therefore, it can be the perfect example of smart growth if introduction greenways initiate more effectively along with some attraction spots for Leisure.

  • Study of Covid-19 - Related Ecological Habitat of College Students: A
           Survey

    • Authors: Anatolii Hrynzovskyi; Saimah Khan, Rohan Srivastava, Abdul Rahman Khan
      Abstract: In recent years, the interaction of people with the surrounding ecological environment has become increasingly unsafe for health, namely the person' physical and mental capabilities. This is especially true of the younger generation, like students of higher educational institutions, who have weakened immunity due to a busy study schedule, constant mental overload and stress. That is, health, as a sign of the quality of life of a student, is associated with the ecological situation and lifestyle, therefore, is one of the main concepts of human ecology. The influence of additional negative factors, such as stress and restrictions associated with the Covid-19 pandemic, greatly increases the risk of developing students' mental health problems. Unexpected isolation related to Covid-19 has caused disruption to daily routines, especially in students. The sudden change in the learning environment and limited social interactions and activities posed an unusual situation for children's developing brains. The study aim is to investigate and identify the psychological threats posed by students of different ages (under 20, between 21–25, and 26-32) in this pandemic of COVID-19. It was found that 28.0% of students were often nervous and stressed in the age group under 20, in contrast to 26.5% and 11.1% in groups 21 to 25 and over 26, respectively. In the younger group of students, 10.2% of students never felt upset, in the group of 21-25 years old - 8.3% and over 26 years old - 5.6%. It was concluded that it is mandatory to assess the student's psychological health and to plan for necessary support mechanisms, mainly during the recovery phase, because depression, stress, fear of getting infected, fear of losing a loved one, fear about getting jobs and related academic issues, disturbance in sleeping pattern, increase in duration of screen time, etc., were found to be common among students of all age groups.

  • Oak and others, new to Poland, hosts of mistletoe Viscum album subsp.
           album in the city of Toruń and its immediate vicinity

    • Authors: Lucjan Rutkowski; Andrzej Nienartowicz, Mieczysław Kunz
      Abstract: The paper presents the distribution of localities of seven tree taxa, identified as new hosts of mistletoe in Poland, in the city of Toruń. Particular attention was paid to the description of a site with mistletoe on an oak identified as Quercus x rosacea. The reason for this is that native oaks are rare hosts of mistletoe in Central and Eastern Europe and this is the first finding of such a host–parasite association in Poland. The occurrence of all eight host species at 14 sites was compared with the distribution and description of localities and morphological characteristics of both host–mistletoe association components presented in the botanical, ecological and forestry literature.

  • Studies of the silkworm enzyme activity and their correlations with
           economic variables

    • Authors: Sergiy Yeremenko; Mohd Younus Wani, Nisar Ahmad Ganie, Mushtaq Rasool Mir, Shakeel Ahmad Mir, Munazah Yaqoob, Imtiyaz Murtaza, Tanveer Ahmad Wani, Mohd Farooq Baqual, Oleksii Sukennikov
      Abstract: The experiment was conducted to analyse the larval performance and economic traits of bivoltine silkworm breeds of silkworm (SK-1, SK-6, SK-22, SK-28, SK-33, CSR4, CSR2, NB4D2, DUN6 and APS4) during spring season. The haemolymph total protein, succinate and gultamate dehydrogenase activities were estimated and their correlation with economic traits were also worked out. The results of the study confirmed that among ten bivoltine silkworm breeds, highest haemolymph SDH activity of 3.47 µmoles/ml/mgprotein/min was recorded in the silkworm breed SK1 and least SDH activity of 1.58 µmoles/ml/mg protein/min was recorded in the breed APS4. The highest peak of succinate dehydrogenase activity of 2.65 µmoles/ml/mg protein/min was observed on 7th day of the 5th instar and lowest peak of succinate dehydrogenase activity of 2.39 µmoles/ml/mg protein/min was observed on 4th day of the 5th instar. GDH activity of 0.46 µmoles/ml/mg protein/min was recorded highest in the silkworm breed SK1 and lowest of 0.15 µmoles/ml/mg protein/min was recorded in silkworm breed APS4. The highest peak of haemolymph GDH of 0.36 µmoles/ml/mg protein/min was recorded on 7th day of 5th instar and lowest peak of 0.26 µmoles/ml/mg protein/min was recorded on 4th day of 5th instar. The correlational studies revealed that haemolymph total protein, SDH and GDH were found to be positively corelated with yield by weight and number (cocoon), weight of mature larvae, shell weight ,cocoon weight, shell ratio percent, silk productivity, rate of pupation, fecundity, raw silk percentage  and length of filament. Thus, the study revealed that silkworm breeds like SK1, SK6, SK22 and SK28 as productive breeds and hence may be used for future breeding programmes for evolution of new robust silkworm breeds

  • Allometric relationships among tree-size variables under tropical forest
           stages in Gia Lai, Vietnam

    • Authors: Manh Hung Bui; Van Khoa Phung, Thi Bich Phuong Nguyen, Van Quy Nguyen, Bernard Dell
      Abstract: Allometric models play an undeniable role for estimating hard-to-measure quantities such as volume, biomass and carbon stock in forests. However, so far there has been limited model development for native forests in Vietnam. Therefore, this study was conducted to build and analyze the effectiveness of nonlinear and mixed models for secondary and old-growth forests in Gia Lai, Vietnam. The study measured diameter at breast height, total height, commercial height and crown width of forest trees in 20 plots (10 plots for each forest stage). The results showed that diameter had the strongest relationship with height. In the secondary forest, the Power, Korf and Ratskowky models were the best for pairs of variables, while Prodan, Weibull and Power models were the best fit in the old-growth forest. The nonlinear mixed-effect models were better than classic nonlinear models in both forest stages. Fixed and mixed models developed in this study are very valuable for estimating difficult-to-measure quantities and contribute to effective forest management in the study region.

  • The intensity of biofilm formation by heterotrophic bacteria isolated from
           soil ferrosphere

    • Authors: Nataliia Tkachuk; Liubov Zelena
      Abstract: The intensity of biofilm formation by heterotrophic bacteria possessed ammonifying ability (Bacillus simplex ChNPU F1, Streptomyces canus NUChC F2, Streptomyces gardneri ChNPU F3), ammonifying and iron-reducing ability (Fictibacillus sp. ChNPU ZVB1) previously isolated from soil ferrosphere was studied. Methods used: indirect measurement of the biomass of the bacterial biofilm using the adsorption/desorption of crystal violet, the aggregation test (to determine aggregation properties), the salt aggregation test (to determine hydrophobicity). The correlation analysis between the intensity of biofilm formation and aggregation of strains showed a significant positive correlation. The studied strains of microorganisms did not show high adhesive properties, they were moderately-adhesive (B. simplex, S. canus and S. gardneri) and weakly-adhesive (Fictibacillus sp.). It is supposed that the role these bacteria in the microbial damage of materials is determined preferably by bioelectrochemical reactions (iron-reducing bacteria) and the production of corrosive and/or antimicrobial metabolites (ammonifying and iron-reducing bacteria), but not by the biofilms formation. The prospect of further research is to analyze the antagonistic properties and biofilm formation of heterotrophic bacteria under co-cultivation conditions, in particular, with sulfate-reducing bacteria.

  • Impact of climate change on snow covered area over the transboundary
           Jhelum River basin of Himalayas region using Remote Sensing

    • Authors: Saira Munawar; Ghani Rahman, Muhammad Miandad, Mehtab Ahmed Khan, Humayun Ashraf, Saba Yousaf Zai
      Abstract: Climate change is one of the pertinent issues for the 21st century mainly for the transboundary river basins because it has parallel impacts on the hydrosphere and cryosphere. The temperature changes impacted the snow-covered area (SCA) of the river basins. MODIS MOD10A2 product data was used to delineate the SCA for the Jhelum River basin. The catchment is further divided into elevation zones using DEM to delineate the SCA for every zone. The temperature changes were plotted against the SCA, and correlation analysis was used to see the impact of climate change on the SCA. The seasonal trend of SCA has depicted an increase in SCA during the spring and summer seasons and decreasing trend during autumn while winter shows stability. The snow cover depletion curve (SCDC) showed that snow is maximum in December, January, and February while its minimum during July and August. The correlation analysis of temperature and SCA for the period of 2001-2017 illustrated the inverse relationship, which depicted that a slight increase in temperature may trigger the fastest depletion in the snow-covered areas generating water issues for snow/glacier-fed river basins.

  • Application of MCE-AHP technical for modelling paddy zoning: A case study
           in Vietnam

    • Authors: Tong Thi Hanh; Mai-Phuong Pham, Nguyen Thi Thu Nga, Samreen Riaz Ahmed, Altaf Hussain Lahori, Nataliia Borodina
      Abstract: The main aim of present study was to determine the most suitable land for paddy via AHP - GIS and Remote Sensing. Ba Thuoc district - Thanh Hoa province was selected as the target area to conduct the experimental set-up. As per opinion of scientists and the guidance of World Food Organization (FAO) on agricultural crops, the criteria selected to estimate the ecological adaptation of crops include soil type, soil texture, soil depth, soil pH, N (%), elevation, slope, distance from rivers, yearly precipitation, low-average and high temperature, average sunny hours, saltwater intrusion. The land suitability map was generated by superimposing the component maps considering the weighting of the criteria. The obtained results showed that in the experimental area nearly 8.26% of the land-use region was very appropriate for rice growing, 26.29% was observed medium appropriate, 43.35% was less appropriate and 22.1% was not fit for paddy cultivation. Overall, the data may be of value for country government, policy makers, managers as well as local authorities to induce local farmers for paddy production on most suitable areas

  • New locality of Botrychium matricariifolium in south-eastern Poland –
           characteristics of the habitat and some plant traits

    • Authors: Tomasz Wójcik; Maria Ziaja
      Abstract: Botrychium matricariifolium is a critically endangered species in Poland. In 2020, a new locality of this rare fern was found in the Góra Chełm forest reserve (Strzyżowskie Foothills). The population comprised 58 individuals. The fern was found in the Carpathian beech fertile complex Dentario glandulosae-Fagetum at a forest margin located near an unused quarry. The community comprised 29 vascular plant species. The dense layer of trees (90%) was composed of Acer pseudoplatanus, Abies alba, and Fagus sylvatica. The greatest coverage in the undergrowth was achieved by Dentaria glandulosa, Dentaria bulbifera, Galeobdolon luteum, and Mercurialis perennis. The mean height of the ferns was 14.9 cm. The trophophores had 3 branches each and were 1.1-3.4 cm long (mean: 2.1 cm). They had 5 to 9 pinnae. The length of the sporophore ranged from 2.3 to 8.3 cm (mean: 5.1 cm). It had from 12 to 183 sporangia (mean: 62). In 2021, the locality was re-verified, and 30 sporulating individuals were recorded. No factors threatening the species were noted. The population is in good condition and does not require any special active protection measures.
