Priority needs für sustainable mountain development across scales
Authors: Geschke Jonas , Urbach Davnah , Fischer Markus 
Published: September 2024

Abstract

Sustainable development in mountains is essential, for themselves and beyond. However, mountains are under threat by inter alia climate and land use changes, and a target-oriented implementation of measures towards achieving the Sustainable Development Goals (SDGs) is urgent. Therefore, sustainable mountain development needs focus from decisionmakers and management, balancing interests of stakeholders across different regions and governance levels. Here, we identify SDG priority needs throughout different mountain regions of the world. While we found the Northern Andes most need to protect and restore biodiversity, the Central Andes need quality education. In the European Alps, sustainable consumption and production should be priority. For the Himalaya, combating climate change is most needed. Globally, life on land, quality education, and good health and well-being are the SDGs with the highest consensus priority. The results show how different priority perspectives can be consolidated, and where options for synergistic sustainable mountain development are.

Authors: liao ling 
Published: September 2024

Abstract

This study evaluates the global inequalities of breast cancer incidence and mortality from 2022 to 2050 with the latest GLOBOCAN estimates. It focuses on disparities across continents, age groups and Human Development Index (HDI) levels. In 2022, Africa shows the highest positive slope values of age-standardized rates (world) of mortality vs. incidence, both for those under 40 (0.346) and those 40 and older (0.335). These values contrast with those for Asia (0.085, 0.208), Europe (0.002, -0.014), Latin America and the Caribbean (0.17, 0.303), Northern America (-0.078, -0.188), and Oceania (0.166, -0.001). In both age groups, lower HDI levels are correlated with higher slope values and vice versa. Projections to 2050 indicate significant increases in the burden of breast cancer, with persistent yet varied disparities and differences. This highlights the need for differentiated strategies in breast cancer prevention, early-stage diagnosis, and treatment.

Abstract

The COVID-19 pandemic led to significant disruptions in schooling worldwide. This study aims to evaluate and compare the impact of the pandemic on student mathematics achievement across eight representative countries/regions, using data from the Programme for International Student Assessment (PISA) 2022. The multilevel random forest (RF) method was employed to account for the effects of national, school, family, and individual contexts, as well as the hierarchical structure of the PISA data. The results show that the multilevel RF model outperformed the traditional multilevel model in terms of predictive accuracy. School closures were found to have the most significant negative impact, while school support and self-directed learning had positive effects. Additionally, the impact of COVID-19 on student mathematics achievement varied substantially across different countries/regions and subgroups. The findings are discussed regarding the resilience of education system, educational inequities, and their implications for policy and methodology.
Enhancing smallholder agricultural production through sustainable use of shallow groundwater in the Borkena catchment, Awash River Basin, Ethiopia

Published: September 2024

ABSTRACT
With increasing shallow groundwater use for agricultural purposes, understanding the spatiotemporal variability in recharge rates, storage capacity, and its interaction with surface waters becomes crucial for its sustainable management. An integrated SWAT–MODFLOW model is developed to assess shallow groundwater availability in the Borkena catchment. The model is calibrated using streamflow and static groundwater level data. Results show that groundwater recharge in the catchment is 85 mm/a, representing 11% of the mean annual rainfall. Shallow groundwater resources exist across nearly 42% of the Borkena catchment. The percentage of shallow groundwater withdrawal to groundwater recharge is very low (0.1%), signifying the potential for increased shallow groundwater development. However, caution must be taken as its uncontrolled expansion may result in a high risk of depletion. This integrated modeling is one of the few efforts conducted to provide important information regarding shallow groundwater potential in the Borkena catchment, which is essential for the resilience of small-scale producers in the continued growing water demand and climate change.

ABSTRACT

Waste treatment for pollution control is a hot topic being studied and has received growing attention. In this study, spent bleaching earth (SBE), a waste material from the oil refineries, was pyrolyzed in a N2 atmosphere to produce an environmentally sustainable clay/carbon composite (SBE@C (500 °C)). SBE@C (500 °C) was tested for its ability to remove methylene blue (MB) from water. The Langmuir model best explained the adsorption isotherms, with maximum adsorption capacity of 29.54 mg/g (MB solution (10–60 mg/L)). The pseudo-second-order kinetic model effectively described the adsorption kinetics data. Thermodynamic parameters indicated spontaneous and endothermic processes. The impact of coexisting cations on MB adsorption by SBE@C (500 °C) decreased in the following order: Fe3+ &gt; Al3+ &gt; Mg2+ &gt; K+ &gt; Na+. The ionic strength results indicated that increasing the concentration of Na+ ions led to a decrease in adsorption capacity. MB removal was greatest at pH level of 8. The adsorption mechanisms involved π–π interactions, electrostatic interactions, and changes in physicochemical properties. After 3 cycles, SBE@C (500 °C) may be recycled up to 11 times before completely losing its adsorption capacity. Overall, SBE@C (500 °C) shows promise for removing MB from wastewater, while mitigating secondary pollution from SBE.

Key Points

This study, the sole randomized trial of its kind, proposes guidelines for fluid balance management in continuous KRT (CKRT) patients using bioimpedance.Despite this, bioimpedance analysis–guided volume management did not influence the proportion of patients achieving estimated euvolemia at 7 days into CKRT.Further investigation is needed to assess whether bioimpedance analysis guidance can facilitate rapid fluid removal in the early phase of CKRT for patients with AKI.

Background
Ultrafiltration with continuous KRT (CKRT) can be used to manage fluid balance in critically ill patients with AKI. We aimed to assess whether bioimpedance analysis (BIA)–guided volume management was more efficacious than conventional management for achieving estimated euvolemia (e-euvolemia) in CKRT-treated patients.

Methods
In a multicenter randomized controlled trial from July 2017 to July 2020, the patients with AKI requiring CKRT were eligible if the weight at the start of CKRT had increased by ≥5% compared with the weight at the time of admission or total body water (TBW)/height (H)2 ≥13 L/m2. We randomly assigned 208 patients to the control (conventional fluid management; n=103) and intervention groups (BIA-guided fluid management; n=105). The primary outcome was the proportion of attaining e-euvolemia 7 days postrandomization. E-euvolemia was defined as the difference between TBW/H2 D7 and D0 was <−2.1 L/m2, or when TBW/H2 measured on D7 was <13 L/m2. The 28-, 60-, and 90-day mortality rate were secondary outcomes.

Results
The primary outcome occurred in 34 patients in the intervention group and 27 in the control group (47% versus 41%; P = 0.50). The mean value of TBW/H2 measured on D7 was the same at 13.9 L/m2 in both groups. The differences between TBW/H2 D7 and D0 were −1.13 L/m2 in the intervention group and −1.08 L/m2 in the control group (P = 0.84). Patients in the intervention group had a significantly higher proportion of reaching e-euvolemia on D1 than those in the control group (13% versus 4%, P = 0.02). Adverse events did not differ significantly between the groups.

Conclusions
BIA-guided volume management did not affect the proportion of reaching the e-euvolemia at 7 days of the start of CKRT.

Authors: Олькова А.С. , Товстик Е.В. 
Published: September 2024

Статья посвящена проблеме выбора информативных показателей экологического состояния почвы с низкоуровневым стресс-фактором. Цель данной работы – сравнение токсикологических (ex situ) и биоиндикационных показателей (in situ) почвы, находящейся в условиях загрязнения, засухи, повышенной кислотности. В образцах почвы определяли численность зимо- генной и олиготрофной микрофлоры, активность экзоферментов каталазы и уреазы, острую ток- сичность почвенных вытяжек в тестах на Paramecium caudatum и Escherichia coli. Большинство реакций, проявившихся ex situ и in situ, были горметическими или равными контролю. Увеличение численности по сравнению с контролем наблюдали у олигокарбофилов в среднекислой почве (в 13 раз), у олиготрофов в почве, испытавшей засуху (в 22 раза), у амилолитиков в загрязненной и кислой почве (в 6 раз), а также в засушливой (в 1.6 раза). Достоверно уменьшались в условиях приложенных факторов значения следующих показателей: численность аммонификаторов при кадмиевом стрессе низкого уровня (в 3 раза) и средней кислотности почвы (в 5 раз), целлюлозо- литиков в ответ на кислотность почвы (в 2.5 раза) и при засухе (в 1.7 раза), активность уреазы в среднекислой почве (в 1.7 раза). Кроме того, в 1.4 раза возрастал индекс токсичности для среднекислой почвыв тесте на P. caudatum.
The article is devoted to the problem of choosing informative indicators of the ecological state of soil with a low stress factor. The purpose of this work is to compare toxicological (ex situ) and bioindic- ative indicators (in situ) of soil under conditions of pollution, drought, and increased acidity. The number of zymogenic and oligotrophic microflora, the activity of catalase and urease exoenzymes, including the acute toxicity of soil extracts in tests for Paramecium caudatum and Escherichia coli were determined in soil samples. Most of the reactions observed ex situ and in situ were hormetic or equal to the control. As compared to the control, an increase in the number was noted in oligocarbophiles in moderately acidic soil (by 13 times), in oligotrophs in drought-exposed soil (by 22 times), in amylolytics in contaminated and acidic soil (by 6 times), as well as in arid soil (by 1.6 times). The values of the following parameters sig- nificantly decreased in the conditions of the applied factors: the number of ammonifiers under low-level cadmium stress (by 3 times) and moderate soil acidity (by 5 times), cellulolytics in response to soil acidity (by 2.5 times) and under drought (by 1.7 times), urease activity in moderately acidic soil (by 1.7 times). In addition, the toxicity index for moderately acidic soil in the test for P. caudatum increased by 1.4 times.

Поглощение растениями СО из атмосферы в процессе фотосинтеза и дыхание почвы в наибольшей степени определяют углеродный баланс наземных экосистем. На основе 3-летних наблюдений в теплый период года (июль–август2017–2019 гг.) проведена оценка составляющих углеродного обмена древесных растений и почвенного покрова на сплошной вырубке 10-летней давности среднетаежного сосняка черничного в условиях Южной Карелии. Контролем послужили одновозрастные деревья (10–15 лет) и естественные почвы под пологом спелого сосняка черничного. Сопоставление показателей СО2 -газообмена сосны обыкновенной (Pinus sylvestris L.), березы повислой (Betula pendula Roth), ольхи серой (Alnus incana (L.) Moench)и осины (Populustremula L.) выявило в условиях сплошной вырубки более интенсивное связывание СО2 в процессе фотосинтеза относительно его выделения листом при темновом дыхании у всех видов (в 6–10 раз) по сравнению с таковыми у деревьев под пологом спелого древостоя (в 3–6 раз). Наибольшая интенсивность фотосинтеза для одновозрастных деревьев отмечена у лиственных видов относительно сосны как в антропогенно трансформированном биоценозе (16.6–17.6 и 7.4 мкмоль/м2 с), так и под пологом сосняка черничного (11.2–12.3 и 5.5 мкмоль/м2 с). Показан вклад почвенной эмиссии в атмосферный поток СО2 на сплошной вырубке (4.6 мкмоль/м2 с) и под пологом древостоя (5.9 мкмоль/м2 с).Отмечено преобладание внутрисезонной вариабельности на фоне схожих среднемноголетних величин показателей углеродного обмена древесных растений и почвы на обоих экспериментальных участках.
Photosynthetic carbon flux and soil respiration are major determinants of the carbon balance of terrestrial ecosystems. Components of the carbon exchange of woody plants and soils were esti- mated in a 10-year-old clear-cut site of mid-boreal bilberry-type pine forest in southern Karelia during the warm season (July–August) in 2017–2019. The control was trees of the same age (10–15 years) and natural soils under the canopy of a mature bilberry pine forest. A comparison of the parameters of CO2 gas exchange in Scots pine (Pinus sylvestris L.), silver birch (Betula pendula Roth), gray alder (Alnus incana (L.) Moench), and aspen (Populus tremula L.) revealed that photosynthetic uptake of CO2 exceeded its release by foliage during dark respiration in all the species more significantly in the regenerating clear-cutting (6–10-fold) than under mature stand canopy (3–6-fold). The rate of photosyn- thesis in trees of the same age was higher in deciduous species compared to pine both in the clear-cut site (16.6–17.6 and 7.4 µmol/m2·s) and under pine forest canopy (11.2–12.3 and 5.5 µmol/m2·s). The contributions of soil emission to the atmospheric СО2 flux in the regenerating clear-cutting (4.6 µmol/m2 s) and under the stand canopy (5.9 µmol/m2·s) are reported. Intra-seasonal variability of the parameters of carbon exchange in woody plants and soil was high as opposed to the relatively low variation among years in both sample plots.

Abstract
Termites are widely dispersed throughout the tropics and attain the highest diversity and abundance in the rainforests of Africa. Understanding their diversity in areas with human activities can provide insights into the local biodiversity and health of the ecosystem. The present study investigated the abundance and diversity of termite species at the Kwara State University campus. The study area was divided into five zones, and thorough examinations of all microhabitats were conducted to detect termite presence. Random handpicking and transect sampling methods were employed to evaluate termite diversity. There were 353 instances of termites encountered between May 2021 and August 2022. The analysis revealed eight termite species in seven genera and three subfamilies. Among these, Trinervitermes geminatus had the highest relative abundance at 48.7 %, whereas Fulleritermes tenebricus had the lowest at 1.98 %. All identified species belonged to the family Termitidae, with subfamilies Nasutitermitinae accounting for 50.7 %, Macrotermitinae for 37.7 %, and Termitinae for 11.6 % of the species. Grass-feeding Trinervitermes geminatus was the most frequently collected species, followed by fungus-growing Macrotermes subhyalinus; both were found across all five campus zones. The species diversity and richness indices observed in the five zones were moderately high. The considerable abundance of termites within the university campus suggests their significance in the ecosystem. There is a need to document termite species present in an ecosystem with human activities because it helps to monitor biodiversity loss in the environment.
Postovulatory Follicle Degeneration and Atresia in Horse Mackerel Trachurus trachurus from the East Coast of Algeria
Authors: Chikhoune Amirouche , Ichalal Keltoum 
Published: September 2024

Abstract
The present study focuses on the detailed description of postovulatory follicles (POFs) resorption and atresia in horse mackerel from Algerian waters. From February 2013 to February 2014, 155 female horse mackerel were randomly collected. Histological sections of ovaries were analyzed. Few POFs (7.28% of early POFs and 2.91% of old POFs of the total observed oocytes) were detected. Morphological changes of POF resorption were discussed in the current study. No particular shape was observed. Four types of atretic oocytes were determined: α = 34.38%, β = 5.28%, δ = 2.37% and γ = 0.94%, which was reported for the first time in horse mackerel. The incidence of α atresia was higher in the yolked (21.48%) than in the unyolked oocytes (12.89%). α atretic oocytes can be classified into two main types: non-bursting (capsulated, lipoidal and cystic atresia) and bursting (multiple bursts, single bursts, phagocytic bursts and liquified bursts). Further studies are required to better understand the reproductive strategies of fish in relation to postovulatory follicle resorption and atresia.
