In 2014–2018, within the middle part of the Oka River basin, on narrowed and widened sections of its floodplain, were conducted studies of the retreat rate of the channel steep banks. The method of erosional pins was used to determine the rate of changes in the floodplain edge contours on active bank slopes – sections of the relatively straight and meandering Oka channel. We established that in 2014–2017, with low floods, at the level of the lower and middle intervals of channel-forming discharges, lateral erosion was determined not so much by fluvial relief formation as by slope and anthropogenic processes. After the recession of the 2018 flood, which was close in its level and discharge to the average annual values, there was a significant intensification of the bank retreat under the direct influence of the flow and more frequent formation of hollows. The annual data and integrated research results over the five-year period indicate a significant predominance of longitudinal horizontal channel deformations and a slowdown in the rate of transverse deformations, especially in dry years. The significant role of the anthropogenic and slope components in lateral erosion of the Oka channel banks has been established.

The rate of bank retreat was measured using erosion pins on the alluvial banks of the rivers in the Podhale region (the boundary zone between Central and Outer Carpathians) during the hydrological year 2013/2014. During the winter half-year (November–April), the bank retreat was mainly caused by processes related to the freezing and thawing of the ground (swelling, creep, downfall). During the summer half-year (May–October), fluvial processes and mass movements such as lateral erosion, washing out, and sliding predominated. The share of fluvial processes in the total annual amount of bank retreat (71 cm on average) was 4 times greater than that of the frost phenomena. Erosion on bank surfaces by frost phenomena during the cold half-year was greatest (up to 38 cm) on the upper parts of banks composed of fine-grained alluvium, while fluvial erosion during the summer half-year (exceeding 80 cm) mostly affected the lower parts of the banks, composed of gravel. The precise calculation of the relative role of frost phenomena in the annual balance of bank erosion was precluded at some stations by the loss of erosion pins in the summer flood.

Abstract. Photosynthesis provides carbon for the synthesis of macromolecules to construct cells during growth. This is the basis for the key role of photosynthesis in the carbon dynamics of ecosystems and in the biogenic CO2 assimilation. The development of eddy-covariance (EC) measurements for ecosystem CO2 fluxes started a new era in the field studies of photosynthesis. However, the interpretation of the very variable CO2 fluxes in evergreen forests has been problematic especially in transition times such as the spring and autumn. We apply two theoretical needle-level equations that connect the variation in the light intensity, stomatal action and the annual metabolic cycle of photosynthesis. We then use these equations to predict the photosynthetic CO2 flux in five Scots pine stands located from the northern timberline to Central Europe. Our result has strong implications for our conceptual understanding of the effects of the global change on the processes in boreal forests, especially of the changes in the metabolic annual cycle of photosynthesis.

Gardens and horticulturists play an increasingly important role in plant conservation, both in situ and ex situ. Integrated research and conservation of species intends to work across fields to connect science to conservation practice by engaging actors from different sectors, including gardens. The case of integrated conservation of Quercus brandegeei, a microendemic oak species in Baja California Sur, Mexico, is presented as an example of a collaboration between gardens and academic researchers to create a species-specific conservation plan that incorporates horticultural knowledge.

Abstract Organochlorines have diverse structures and applications and are included in the list of persistent organic pollutants (POPs) due to their toxicity and environmental persistence. The reduced capacity of conventional wastewater treatment plants to remove these compounds encourages the development of cost-effective and efficient remediation approaches. Fungal biotechnology can contribute to the development of these technologies through their enzymatic machinery but faces several drawbacks related to the use of dispersed mycelium. In this sense, investigations concerning the degradation of organochlorines using immobilized fungi demonstrated an increase in contaminants removal efficiency compared with degradation by free cells. Despite this interest, the mechanisms of immobilized fungi have not been comprehensively reviewed. In this paper, recent advances of laboratory and field studies in organochlorine compounds removal by fungi were reviewed, focusing on the role of immobilization techniques. Firstly, the mechanisms of organochlorines bioconversion by fungi and the factors affecting enzyme activity are elucidated and discussed in detail. Then, the main targeted compounds, fungi, technics, and materials used for immobilization are discussed, as well as their advantages and limitations. Furthermore, critical points for future studies of the fungi immobilization for organochlorines removal are proposed.

Abstract. The magnitude of termite methane (CH4) emissions is still an uncertain part of the global CH4 budget and current emission estimates are based on limited field studies. We present in-situ CH4 emission measurements of termite mounds and termite mound sub samples, performed in the Amazon rain forest. Emissions of five termite mounds of the species Neocapritermes brasiliensis were measured by use of a large flux chamber connected to a portable gas analyser, measuring CH4 and CO2. In addition, the emission of mound sub samples was measured, after which termites were counted, so that a termite CH4 and CO2 emission factor could be determined. Mound emissions were found to range between 17.0–34.8 nmol mound−1 s−1 for CH4 and between 1.6–13.5 μmol mound−1 s−1 for CO2. A termite emission factor of 0.32 μmol CH4 gtermite−1 h−1 was found, which is twice as high as the only other reported average value for the Amazon. By combining mound emission measurements with the termite emission factor, colony sizes could be estimated, which were found to range between 50–120 thousand individuals. Estimates were similar to literature values, and we therefore propose that this method can be used as a quick non-intrusive method to estimate termite colony size in the field. The role of termites in the ecosystems CH4 budget was evaluated by use of two approaches. Termite mound emission values were combined with local termite mound density numbers, leading to an estimate of 0.15–0.71 nmol CH4 m−2 s−1 on average emitted by termite mounds. In addition, the termite CH4 emission factor from this study was combined with termite density numbers, resulting in an estimate of termite emitted CH4 of ~1.0 nmol m−2 s−1. Considering the relatively low net CH4 emissions previously measured at this ecosystem, we expect that termites play an important role in the CH4 budget of this Terra Firme ecosystem.

Stress protectors (adaptogens) are among the most important factors that regulate growth processes at all stages of plant development. This article presents results of field studies of the effect of new synthetic plant growth regulators of stress protectors (adaptogens) on the elements of productivity and yield of spring oats of the Skakun variety. The obtained results during the research showed that all the studied derivatives of peredazinones are adaptogens and they contribute to an increased productivity and increased yield of spring oats. We studied the effect of pre-sowing treatment of seeds with new synthetic plant growth regulators of stress protectors on the quality indicators of cereal production of Skakun oats (protein, starch and amylolytic enzymes content in the cereal). Pre-sowing treatment of oat seeds increases the amount of protein in the cereal up to 15%, starch – up to 25%, amylase – up to 20%. We proved the ability of stress protectors to minimize the negative impact of heavy metals (lead, zinc) on agrophytocenoses, which will make it possible to obtain environmentally friendly cereal products when cultivating oats in anthropogenically polluted areas of the Saratov Oblast.

<strong>Abstrak: </strong>keberadaan<strong> </strong>berbagai kajian dan literatur tentang gender tidak serta merta merubah pandangan masyarakat tentang keadilan gender. Sebab, kajian gender tetapi memiliki pendukung dan penentang. Ada pendapat bahwa kajian gender berupaya merubah ajaran agama itu sendiri. Dalam kajian gender selama ini, ditemukan banyak pihak yang ikut berkontribusi bagi muncul dan berkembangnya paham yang bias gender dalam masyarakat Muslim, khususnya di Indonesia. Di antara pihak yang bertanggungjawab terhadap kelestarian paham yang diskriminatif terhadap perempuan adalah para pemuka agama yang diwakili oleh para ustaz dan ustazah dimana mereka memainkan peran sebagai penyampai ajaran agama kepada masyarakat Muslim. Artikel ini mengkaji pandangan para ustaz dan ustazah terhadap ketidakadilan gender yang dilihat dari latar belakang suku masing-masing, sehingga akan terungkap perihal adakah kaitan antara latar belakang suku seorang ustaz dan ustazah terhadap persepsi mereka tentang ketidakadilan gender. Didasari oleh studi lapangan, dimana data penelitian diperoleh dari angket dan wawancara, kajian ini menemukan bahwa masih ditemukannya pemahaman bias gender dalam persepsi ustaz dan ustazah di kota Medan. Kajian ini diharapkan dapat memberikan kontribusi bagi kajian gender di Indonesia.  <strong></strong><br /><strong> </strong><br /><strong>Kata Kunci: </strong>ustaz, ustazah, ketidakadilan, gender, suku<br /><strong> </strong><br /><strong>Abstract: The Perception of Islamic Preachers about Gender Bias Reviewed From Ethnic Group Backgrounds.</strong> The existence of various studies and literature on gender does not automatically change the society's opinion about gender equality. As such, supporters and opponents of the idea are readily found. One opinion goes as far as saying that gender studies try to alter the teachings of religion itself. In the gender studies has been found that many contributed to the emergence and development of gender biased ideology in Muslim societies, especially in Indonesia. Among those responsible to discriminatory preservation of women are religious leaders who are represented by <em>ustaz</em> and <em>ustazah</em> where they play the role of religious teachings to the Muslim community. This article examines the opinions of <em>ustaz</em> and <em>ustazah</em> on gender inequality realized from the background of each ethnic group, so it will be revealed about whether there is a link between ethnic background of an <em>ustaz</em> and <em>ustazah</em> to their perception of gender injustice. Based on field studies, where the research data was obtained from questionnaires and interviews, this study found that there is an understanding of gender bias in <em>ustaz</em> and <em>ustazah</em> perceptions in Medan city. This study is expected to contribute to gender studies in Indonesia.<br /> <br /><strong>Keywords:</strong> ustaz, ustazah, injustice, gender, ethnic group
