The geneology of ecology term in first period of Turkey Turkish

Türkiye Türkçesinde ekoloji kavramı ilk defa Bahâ Tevfik ile Ahmed Nebîl tarafından Vahdet-i Mevcȗd Bir Tabî'at Âliminin Dini adıyla tercüme etmiş oldukları metinde 1911 yılında kullanılmıştır. Türkiye Türkçesinde ekoloji sözcüğünün girdiği 1911 yılından ilk kitabın yazıldığı 1965 yılına kadar olan süre ilk dönem olarak tanımlanmıştır. Ekoloji alanında ilk doktora Almanya'da Asaf Irmak tarafından yapılmıştır. Türkçede ilk ekoloji ders notu Asaf Irmak tarafından 1934 yılında hazırlanan Orman Ekolojisi ders notudur. Yükseköğretim kurumlarında Toprak İlmi ve Ekoloji dersi 1934 yılında Orman Fakültesi ders programında yer almıştır. Ekoloji ile ilgili ilk akademik birim 1943 yılında Toprak İlmi ve Ekoloji Anabilim Dalı olarak Orman Fakültesinde kurulmuştur. Aynı kurumda 1950 yılında ise Orman Ekolojisi dersi olarak bağımsız bir ders niteliğine kavuşmuştur. Yazılan ilk kitabın da Akif Kansu tarafından 1965 yılında yazılan Böcek Ökoloji ve Epidemiyolojisi isimli eserin olduğu tahmin edilmektedir. 1911 yılında Türkçeye giren ekoloji kavramı, 1930'lu yıllardan sonra sınırlı bilim alanında kullanılmaya başlanmış ve 1950'den sonra ekoloji terimleri ve kavramlarının kullanımı yaygınlaşmıştır. 1911-1965 yılları arasında ekolojinin temel terim ve kavramlarına, ekolojinin alt dallarına ve ekosistemin çeşitlerine yönelik bilgilerin Türkçeye çevrilmesine yönelik bilimsel çalışmaların olduğu görülmektedir. Böylece bu dönemde daha sonraki yıllarda yapılacak olan ekoloji çalışmalarının terim ve kavram altlığı oluşturulmuştur.

Evaluation of the machinability of CW614N brass alloy

Brass alloys are widely used materials for general and industrial applications. However, the lead content in them forces manufacturers to develop new ecological types, the properties of which must be gradually specified in order for the product to be produced and processed more efficiently. The article deals with the evaluation of the machinability of CW614 brass by investigating the influence of technological parameters on the surface roughness of the machined surface and the intensity of vibrations during machining. The measured data were statistically processed; with the help of regression analysis, mathematical formulations of the influence of input parameters on monitored variables were defined and based on them, functional dependencies were plotted in the MATLAB software application. The results showed that at the CW614N brass alloy machining, the feed rate has the greatest influence on the surface roughness Ra, but the depth of cut has the greatest influence on the vibration intensity.

HEMATOLOGICAL PROFILE OF CLINICALLY HEALTHY ADULT KAZAKH HORSESZHABE BREED TYPE OF THE KAZAKHSTAN

The article illustrates the data of studies of hematological indicators of the Kazakh breed of horses of the Zhabe type. To obtain a hematological profile, whole blood samples of 54 clinically healthy adult horses of the Type Zhabe of both sexes, raised on the pure pasture content of the farm "Kyzylsok" Zhambyl region, Muzey Zhambyl, Seriktas, were examined on the hematological analyzer MS 4-3Vet (France). The results of the blood test were recorded in winter and the intervals were set especially for erythrocyte parameters: hematocrit (Hct) 35.8 - 49%, hemoglobin 10.8–16.7 g/dl, the number of erythrocytes - 6.83–9.28 (m/mm3); leukocytes (m/mm3) - 9.41-24.37, lymphocytes % - 26.9–49.8 and monocytes % 1.5–5.9; platelet count 312-710 (m/mm3). Significant (P <0.05) differences were noted for the number of red blood cells, the total number of red blood cells, the number of leukocytes (TLC), depending on gender. In addition, clearly differentiable morphometric and morphological signs of erythrocytes, leukocytes (lymphocytes and monocytes) and thrombocytes were noted. Under the influence of the peculiarities of the habitat, an ecological and geographical type of the Kazakh horse, which is called Zhabe , has been formed in the mountainous regions of the republic, having pronounced morpho-hematological characteristics that provide an optimal level of regulation of vital aNctivity and stability of the organism. The hematological indicators indicated here can help in monitoring the health status of horses with hard maintenance through the use of diagnostics in veterinary medicine.

Metagenomic analysis reveals hidden links between gut microbes and habitat adaptation among cave and surface dwelling Sinocyclocheilus species.

Intestinal microbes are closely related to vital host functions such as digestion and nutrient absorption, which play important roles in enhancing host adaptability. As a natural "laboratory", caves provide an outstanding model for understanding the significance of gut microbes and feeding habits in the habitat adaptability of hosts. However, research on the relationship between gut microbes, feeding habits, and the adaptability of troglobites remains insufficient. In this study, we compared the characteristics of the intestinal microbes of Sinocyclocheilus cavefish and surface fish and further established the relationship between intestinal and habitat microbes. Furthermore, we conducted environmental DNA (eDNA) (metabarcoding) analysis of environmental samples to clarify the composition of potential food resources in the habitats of the Sinocyclocheilus cavefish and surface fish. Results showed that the structure of the Sinocyclocheilus gut microbes was more related to ecological type (habitat type) than phylogenetic relationships. While horizontal transfer of habitat microbes was a source of gut microbes, hosts also showed strong selection for inherent microbes as dominant microorganisms. Differences in the composition and structure of gut microbes, especially dominant microbes, may enhance the adaptability of the two Sinocyclocheilus fish types from the perspectives of food intake, nutrient utilization, and harmful substance metabolism, suggesting that food resources, predation patterns, intestinal flora, digestive and absorptive capacity, and feeding habits and preferences are linked to habitat adaptability. These results should facilitate our understanding of the significance of fish gut microbes to habitat adaptation and provide a new perspective for studying the adaptive mechanisms of cavefish.

Conservation Biology of Endangered Wild Walnut in Tianshan Valley, Xinjiang

Wild walnut belongs to the walnut family in Tianshan Valley of Xinjiang. Tertiary tree species in Central Asia and endangered plant under state protection. Its main distribution areas are as far as the Western Tianshan Mountains and Pamir-Alai Mountains of the former Soviet Union, and it is only distributed in Dekuztala County of Xinjiang, China. It is of great scientific value to study the origin and evolution of cultivated walnut, paleofloristic changes, paleogeography, Tertiary and Quaternary climatic changes. Due to the narrow distribution of wild walnut in Xinjiang, harsh desert conditions, climate change, human disturbance, habitat fragmentation and other factors, wild walnut in Xinjiang is facing the risk of extinction, and it is urgent to carry out research on conservation biology and conservation genetics. In this paper, floristic, community and plant population research and analysis methods were adopted [1][6]. In this paper, the floristic composition, plant ecological type structure, plant climate and soil water characteristics of wild walnut community, age structure of wild walnut population, fluctuation cycle and evolution trend of population age composition, population growth characteristics, phenotypic plasticity of seeds and compound leaves, and biomass allocation were analyzed comprehensively in Xinjiang Nature Reserve. And put forward scientific protection countermeasures.

Soil carbon stock in different of mangrove ecosystem in Mahakam Delta, East Kalimantan, Indonesia

Mangrove forests serve as a buffer against sedimentation from the mainland into the sea, protect the area from coastal erosion, and prevent seawater intrusion in some ecological types of coastal environments. Additionally, because soil and below-ground biomass retain a significant quantity of carbon, they are essential for carbon sequestration. The current study seeks to estimate the soil organic carbon stock of mangroves associated with natural regeneration, mangrove rehabilitation areas and abandoned shrimp ponds, in Mahakam Delta, East Kalimantan, Indonesia. A 125-meter-long transect line was used to collect data, with three sampling points representing the length of the transect line. Each soil sample was taken at three different depths: 0-50 cm, 50-100 cm, and 100-150 cm. After that, the samples were taken to the laboratory for carbon analysis. The mangrove rehabilitation area had the highest bulk density at 8.64 gr/cm3, followed by natural mangroves along the river border at 7.67 gr/cm3, and abandoned ponds had the lowest at 7.16 gr/cm3. The rehabilitation area had the highest soil carbon stock at 1120 tons/ha, followed by natural mangroves along the riverside at 686 tons/ha and abandoned ponds at 383 tons/ha. In accordance with the study, mangrove rehabilitation regions had larger soil carbon stocks than natural regeneration along the riverside and abandoned ponds. In order to protect the ecologically significant mangrove ecosystem and minimize the effects of climate change, mangrove restoration and rehabilitation are necessary.

Relationship between ecosystem services and farmers’ well-being in the Yellow River Wetland Nature Reserve of China

Understanding the coupling relationship between ecosystem services and farmers' well-being in the Yellow River Wetland Nature Reserve plays an important strategic role in maintaining China’s ecological security and improving the well-being of regional farmers. Based on field research, questionnaire surveys, and other methods, this study took five Yellow River Wetland Nature Reserves in Henan Province as the research object and used a comprehensive multi-index evaluation method to evaluate the level of ecosystem services and farmers’ well-being in the research area in 2000, 2010, and 2020. Moreover, a coupling coordination degree model was used to analyze the coupling relationship between ecosystem services and farmers’ well-being, as well as their spatiotemporal distribution characteristics. The results showed that the ecosystem service perception index of the Yellow River Wetland Nature Reserve increased from 0.579 to 0.826 from 2000 to 2020. The overall well-being index increased from 0.358 to 0.818 during the same period. The comprehensive indices of ecosystem services and household welfare in the five nature reserves were significantly different. From 2000 to 2020, the coupling coordination between ecosystem services and farmers’ well-being in the Yellow River Wetland Nature Reserve gradually improved, and the coupling coordination type changed from the basic coordinated development welfare lagging type to the well-coordinated development welfare and ecological synchronization type. Based on the actual situation of the Yellow River Wetland Nature Reserve, some suggestions are put forward. These include strengthening publicity regarding ecological protection, further developing tourism related to the Yellow River Wetland, increasing investment in environmental protection and management, and perfecting the mechanism of wetland ecological protection. The results of this study can provide a reference for promoting coordination between ecosystem services and farmers’ well-being in the Yellow River Wetland Nature Reserve.

Ecological distribution of modern diatom in peatlands in the northern Greater Khingan Mountains and its environmental implications.

Relationships between diatom assemblages and environmental variables in peatlands of the northern Greater Khingan Mountains are helpful for understanding the indicative significance of diatoms to environment changes, and potentially provide a reference for environmental monitoring and paleoenvironment reconstruction in the edge of monsoon region. In this study, we analyzed modern diatom assemblages and their relationships with environment factors in 30 surface samples from shrubby-herbaceous and herbaceous peatlands based on ordination analysis. Benthic and epiphytic Pennatae diatoms are mainly ecological types, whereas planktonic Centricae diatoms are relatively fewer. The most diverse genera are Pinnularia and Eunotia. Eunotia paludosa and Achnanthidium minutissimum dominated in shrubby-herbaceous peatlands, while Navicula minima and Fragilaria capucina dominated in herbaceous peatlands. The diatom community structures are different in different vegetation types and the diatom species diversity in herbaceous peatlands is higher than that in shrubby-herbaceous peatlands. CODMn and pH are the most important environmental factors affecting diatom species composition and diversity. Eunotia bilunaris, Eunotia mucophila, and Eunotia paludosa can be used as indicators of acidic water environments. Caloneis silicula, Fragilaria capucina, Hantzschia amphioxys, and Navicula radiosa can be applied to indicate the weak alkaline conditions. Eunotia bilunaris and Eunotia paludosa can indicate low conductivity, while Sellaphora pupula indicates the medium-high conductivity. Fragilaria capucina and Navicula radiosa can indicate oligotrophic habitats.

Biternatisporites gen. nov.—a new megaspore genus from the Middle-Carboniferous sediments of the Tunguska basin (Siberian platform, Russia)

The paper presents a new genus, Biternatisporites gen. nov., which is represented by a single species, B. compositus comb. nov.. This genus was found in the Middle Carboniferous sediments (Bashkirian age) of the Tunguska Basin, Russia. A description of the sediments where the new genus was found is given. The area of Biternatisporites gen. nov. represents a double ray system: large rays reach the edge of the megaspore, and small rays go beyond the corners of large rays. The new genus belongs to the first ecological and morphological type of megaspores, in terms of evolutionary development. This type is characterized by a simple morphological structure of the shell, consisting of the distal and proximal sides. On the proximal side there is an area bearing a tetrad scar and rare sculptural elements.

Selection of a Pavement Structure from Technically Established Alternatives Based on Construction Cost, Energy Consumption, and Carbon Footprint

This paper presents a procedure to select a pavement structure from technically established alternatives. The general proposed process relies on calculating the present worth of total cost resulting from construction, maintenance/rehabilitation, energy consumption and carbon footprint during those activities as well as recycling of the materials at their end life. However, depending on data availability, the general process could be reduced to just the construction phase as is the case in most developing countries where required pavement performance data is scarce. The reduced procedure was validated on four types of pavements for six traffic levels and three subgrade types. Under the conditions considered in this study, it was found that concrete pavements have high construction, embodied energy, and carbon footprint costs (the environmental impact represents about 66% of the total cost) as compared to other pavement types. Full-depth asphalt pavements were found to be the best ecological type, their construction cost is a little higher than the environmental one with a distribution of about 53% and 47%, respectively. Inverted pavements seem to be a good alternative to weak subgrades although the costs associated with environmental effects contribute to about 52% of the total cost.

Epidemiological profile of leprosy in a municipality of northeastern Brazil in the face of the challenges of those affected

Objective: To characterize through data obtained from secondary sources the epidemiological profile of leprosy patients in Teresina, Piauí, from 2017 to 2021 in relation to challenges such as disabilities, involvement in children and the rate of deaths related to leprosy. Methods: This is an observational, analytical study of the ecological type, through data from the Notifiable Diseases Information System (SINAN). The variables gender, gender, age, schooling, endemicity index, Physical Disability Degree (DPD), clinical forms and deaths were investigated, through the chi-square test, the Shapiro-wilk test and the odds ratio calculation. Results: There was predominance of the clinical and epidemiological profile with predominantly male gender, color/mixed race, with educational level up to high school, with dimorphous clinical characteristics, however without predominant reactions, but with high DPD Index I. Conclusion: Through the data collected in SINAN it was possible to identify that the population of Teresina currently faces challenges regarding the detection of leprosy in children, is oscillating parameters between hyperendemic and very high endemicity, 9% of the affected population developed some DPD and deaths with higher prevalence were identified in the elderly, however, a scarcity of large number of information from SINAN was observed.

Non-linear models of species' responses to environmental and spatial gradients.

Species' responses to broad-scale environmental or spatial gradients are typically unimodal. Current models of species' responses along gradients tend to be overly simplistic (e.g., linear, quadratic or Gaussian GLMs), or are suitably flexible (e.g., splines, GAMs) but lack direct ecologically interpretable parameters. We describe a parametric framework for species-environment non-linear modelling ('senlm'). The framework has two components: (i) a non-linear parametric mathematical function to model the mean species response along a gradient that allows asymmetry, flattening/peakedness or bimodality; and (ii) a statistical error distribution tailored for ecological data types, allowing intrinsic mean-variance relationships and zero-inflation. We demonstrate the utility of this model framework, highlighting the flexibility of a range of possible mean functions and a broad range of potential error distributions, in analyses of fish species' abundances along a depth gradient, and how they change over time and at different latitudes.

Comparison of avian diversity between urban parks adjacent to mountain and river in the largest megacity Guangzhou, South China

Urban parks can provide a resource for maintaining and increasing bird biodiversity. However, little research has been conducted to show the differences in bird community diversity between parks adjacent to mountains and rivers in the city center of highly urbanized areas. This study analysed whether the bird composition and species diversity differed between parks adjacent to Baiyun Mountain (hillside parks) and Pearl River (riverside parks) in Guangzhou, South China. From January 2018 to December 2020, 137927 birds representing 206 species were recorded. The results indicated that the number of species and individuals of birds were higher in hillside parks than in riverside parks in each season. The number of species and individuals was also higher in hillside parks than in riverside parks in different functional groups according to bird food type, residential type, and ecological type. The number of species shared by the two types of parks was 120. The unique birds' species number in hillside and riverside parks were 67 and 19, respectively. Bird diversity in terms of richness and Shannon index was higher significantly in hillside parks than in riverside parks in summer. Principal component analysis of environmental traits of 18 parks showed that plant traits in parks have relatively high and positive contribution. Correlation analysis indicated that bird diversity was positively affected by water area, the highest altitude, habitats diversity and tree evenness in park, while negatively regulated by building coverage around each park. The top 20 most abundant bird species accounted for 87.5% of the total birds in the study period. Nycticorax nycticorax, Urocissa erythroryncha and Podiceps ruficollis were observed more frequently in hillside parks, while Pycnonotus aurigaster, Passer montanus, Acridotheres cristatellus were observed more frequently in riverside parks. Principal coordinates analysis also indicated that bird communities significantly differed between hillside parks and riverside parks. In conclusion, our findings highlight the importance of conserving mountains and rivers as buffer zones for serious anthropogenic disturbance in the city center. We propose that the conservation of hillside parks is a priority strategy for enhancing urban birds biodiversity.

The risk of respiratory incidents in response to the increase of ozone concentration in the ambient air, in the Silesian Voivodeship, in 2016-2017.

Due to the high level of urbanization and industrialization, Silesian Voivodeship remains a region with the poorest quality ambient air, especially in the winter season in which alarm levels are constantly being exceeded. However, in the summertime, there are observed short-term episodes of high ozone concentrations for which their impact on the population health is poorly documented. The aim of the study was to assess the risk of daily respiratory health problems related to an increased pollutants concentration typical for photochemical smog. In the ecological type of study, secondary epidemiological data were used. They were obtained from the National Health Fund (NFZ) in Katowice and included the number of outpatient visits in primary health care and hospitalizations due to respiratory diseases (J00-J99) and selected acute respiratory incidents registered between 01/01/2016 and 31/08/2017 in the Silesian Voivodeship. In the summertime of both years (2016 and 2017), there were observed short-term episodes of photochemical smog in the study region. Obtained results show a significant increase in the risk of outpatient visits due to total respiratory diseases, and also due to acute pharyngitis, acute laryngotracheitis, bronchitis, and asthma in response to the increase in ozone concentration. Similarly, a significant increase in the risk of hospitalization for all respiratory diseases was found, however, it appeared with a delay of at least two to three weeks. In the case of hospitalization due to bronchitis statistically significant risk was observed 2-4 days after the increase in exposure. The occurrence of registered respiratory incidents was confirmed in response to the increase in ozone concentration, characteristic of the summertime in the Silesian Voivodeship.
