However, the architecture of the burrow of these rodents has been poorly studied. Brandt’s vole (Lasiopodomys brandtii, Radde 1861) is one of the subterranean mammals, and the species is mostly considered a pest on pasture and agricultural fields, particularly during population outbreaks in Mongolia. We aimed to study the architectural differences between old (outbreak over) and new (outbreak rising) burrows of Brandt’s vole related to soil physical properties. In June-August 2020-2021, we randomly selected 10 burrows in Central and Eastern Mongolia along with the same altitude and natural zone. We found differences in the size, the total length of tunnels, and the volumes of sleeping and storage chambers depending on the burrow ages. However, the relation between soil physical factors and burrow architectural features was weak. This weak indicates that Brandt’s vole can dig over the physical barriers of the diverse soils to construct the burrow until the inhabitable architecture. The size of the chamber in the new and the old burrows was significantly different. Based on our preliminary results, we presume that one of the reasons for the rapid decline of the vole population after outbreaks is related to the enlarged size of the chamber. Because the degradation of vegetation cover due to the outbreaks must follow a lack of food and grass materials to fill sufficiently in the sleeping chamber of burrows that might reason to reduce the survival level of the vole colony during the cold winter. \u0000Үлийн цагаан оготны нүхний байгууламж, түүнд нөлөөлөх хөрсний физик хүчин зүйлсийг судалсан дүн \u0000Хураангуй \u0000Үлийн цагаан оготно (Lasiopodomys brandtii, Radde 1861) нь нүхэнд амьдардаг мэрэгчдийн нэг юм.

However, a combination of traditional nomadic rangeland management and government regulations has led to the emergence of Mongolian nomadic pastoralism. Herders who have been sharing their rangelands for four seasons have initiated, agreed upon, and implemented local-specific approaches to rangeland use plans. The government has entered into rangeland use agreements with herders to ensure the proper use of rangeland resources. Experience has shown that the organization of rangeland use areas needs to meet several fundamental principles. These include: providing the participation of all herders in the soum and bagh, clarifying the rights and responsibilities of the primary organizational unit herders' pasture user group, ensuring the coherence of traditional herders' regulations with government regulations, and on this basis between herders' pasture user group and local government Mechanisms for concluding and implementing mining agreements and for herders to integrate them with their own voluntary and government regulations seem to be effective. \u0000Малчдын хамтын зохион байгуулалт, бэлчээр ашиглалтын гэрээний зохицуулалт ба хэрэгжилт \u0000Хураангуй \u0000Өнгөцхөн харвал Монгол орны бэлчээр нутаг нийтийн эзэмшилд, мал сүрэг хувийн эзэмшилд байгаа нь “нийтийн эзэмшлийн эмгэнэл”-ийн сонгодог жишээ болж харагддаг.

The research covered 122 herder households from 13 soums in 8 aimags. A total of 4,560 samples were collected from 1,522 goats representing the main factors determining cashmere quality: ecological habitat, various herd management practices, local breeds, age and sex of goats, and cashmere colour. Cashmere fibre diameter (FD), fibre curvature (FC), and coefficient of variation of fibre diameter (CVFD) were tested in 1,522 samples, and cashmere length was tested in 1,387 samples. The overall mean fibre diameter (MFD) was 16.1 μm, mean length (FL) was 44.9 mm, and fibre curvature (FC) was 61.9°/mm. Cashmere from one-year-old goats was significantly finer than cashmere from older goats (about 1.0 μm, P<0.05). Cashmere from does in the samples tested was significantly finer than cashmere from the bucks. Over the range in mean fibre diameter, from 13.5 to 19.0 µm, fibre curvature declined from 87.8 to 44.2°/mm. Of all cashmere samples, 40.6% belonged to super fine (≤15.5µm), 43.7% and 12.1% had a fibre diameter between 15.51-16.80 and 16.81-17.50 μm, respectively, and were suitable for knitwear. Only 3.6% of samples tested were between 17.51 to 19.00 μm and may only be suitable for weaving. The average CVFD values of cashmere of Mongolian breeds of cashmere goats was 22.5 ± 0.04%, with an individual range of 17.0-26.9%. This shows that it has lesser variation than Alashan white cashmere goats of Inner Mongolia Autonomous Region, China, where CVFD ranged from 27.09% to 41.39%. Compared to cashmere from China, Tajikistan, and Kyrgyzstan, with mean fibre curvature of 46, 46, and 58mm, respectively, the cashmere of local Mongolian breeds of goats would be considered curvier and longer, which makes stronger yarns. Short, higher crimped, softer cashmere may be preferred for woollen-spun yarns, but longer, lower crimped, softer cashmere may be preferred for woven yarn destined for knitwear. Fibre curvature of Mongolian cashmere goats declined an average of 6.1°/mm for a 1µm increase in MFD, which is similar to the 5.8°/mm observed in Chinese Liaoning goats, but less than the 13.6°/mm measured in controlled experiments with Australian goats. Significant differences were found between the cashmere of local Mongolian breeds of goats kept in open, natural rangelands and herded in a nomadic way in distinct ecological conditions of harsh continental climate compared to those breeds of goats kept in intensive farming. This shows the potential to offer distinct quality cashmere from local Mongolian breeds while maintaining proper management and selective breeding.","PeriodicalId":18941,"journal":{"name":"Mongolian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87147075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The water level of most lakes in Mongolia had been steadily increasing from mid-1960s to 1995 and declining from 1996. The purpose of this study is to determine current condition by each ecosystem compartment in and around the Lake Duruutsagaan and to define cause of the lake shrinking and deterioration of ecosystem. The Lake Duruutsagaan ecosystem study was carried out in the following natural elements: climate, hydrology, hydrobiology, forest, soil, pasture, plant species composition, and animals. The lake surface area was slightly decreased by 24.21% from 10.02 km2 in 2003 to 7.59 km2 in 2017. The lake water is highly mineralized, probably due to increases of evaporation of water. Also elevated concentrations of some chemical elements are detected in the lake water, including Phosphorus (22.6 mg L-1) and Arsenic (198 mg L-1). The high concentration of these two elements shown different kind of pollution existed in the lake. Probably, arsenic content in lake water is related to the geological composition of surrounding area, but elevated concentration of P can be attributed to the nutrient pollution due to soil erosion in surrounding area of lake. Species diversity in this lake is limited and only a few species of crustaceans that can tolerate under high salinity and polluted condition are present. All of soil samples have a low content of clay particles (between 2.6-8.5%). According to the soil samples data, pasture land in study area is moderately 80.95%, strongly 7.04% deteriorated due to direct and indirect effects of overgrazing. Especially, natural regeneration is not observed in the forest area. According to the study results, current condition of Lake Duruutsagaan and its surrounding area is indicating the need for some protection and restoration management.","PeriodicalId":18941,"journal":{"name":"Mongolian Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88191942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
