“…In a just published study about Moravian Karst, our area of interest, the impact of villages on pollution by allogeneic was analyzed and confirmed [ 27 ]. We have found a similar effect of settlements in the same villages and watersheds of streams (Tables 2 and 3 ; Figs.…”

“…A karstic watershed has the following characteristics including (1) engulfed streams in karst landscape and (2) underground water channels, caves, and sinkholes due to the solubilization of limestone. These factors make karstic caves and aquifers highly vulnerable to anthropogenic contamination [ 22 – 27 ]. Focused on microbial contamination, special attention in karstic water has been devoted to the transport of pathogenic Escherichia coli and fecal indicator bacteria [ 28 – 36 ].…”

The impact of residential villages on the nontuberculous mycobacteria (NTM) in streams flowing through them has not been studied in detail. Water and sediments of streams are highly susceptible to anthropogenic inputs such as surface water flows. This study investigated the impact of seven residential villages in a karst watershed on the prevalence and species spectrum of NTM in water and sediments. Higher NTM species diversity (i.e., 19 out of 28 detected) was recorded downstream of the villages and wastewater treatment plants (WWTPs) compared to sampling sites upstream (i.e., 5). Significantly, higher Zn and lower silicon concentrations were detected in sediments inside the village and downstream of the WWTP’s effluents. Higher phosphorus concentration in sediment was downstream of WWTPs compared to other sampling sites. The effluent from the WWTPs had a substantial impact on water quality parameters with significant increases in total phosphorus, anions (Cl–and N-NH3–), and cations (Na+ and K+). The results provide insights into NTM numbers and species diversity distribution in a karst watershed and the impact of urban areas. Although in this report the focus is on the NTM, it is likely that other water and sediment microbes will be influenced as well. Graphical Abstract

“…This is mainly due to the vulnerability and sensitivity of karst landscapes, which makes them complex and subjective to study. In terms of study areas, scholars, such as Malá Jitka, Čech Vladimír, Arantza Aranburu, Alexandrowicz Stefan Witold, Howard Limbert, Romeo Eftimi, and others, have explored karst landscapes in the Czech Republic [4], Slovakia [5], Florida [6], Northern Iberia [7], Poland [8], Vietnam [9], and Albania [10]. China is rich in karst landscape and rocky desertification resources, but its research needs to be further deepened, especially in the Yunnan-Guizhou-Sichuan karst area represented by Yunnan Province.…”

A key means of promoting the high-quality development of karst areas is the maintenance of the area’s ecological security. A full recognition of the special ecological function of karst areas, as well as their significance to the surrounding region’s ecological, economic, and social development, is crucial in strengthening the overall strategic deployment of the national ecological construction and the protection and sustainable development of karst landscapes around the globe. In this study, the karst landscape of Puzhehei, Qiubei County, Wenshan Prefecture, Yunnan Province, China, was used as the research object. This study identified ecological source sites through a combination of morphological spatial pattern analysis and landscape connectivity assessment. As a result, 10 factors were selected to construct a comprehensive ecological resistance surface from the natural environment and socio-economic perspective; the resistance surface was corrected by combining the sensitivity of rocky desertification. An ecological corridor and ecological nodes were identified to construct the ecological security pattern based on the minimum cumulative resistance model and circuit theory. The results show that (1) the source areas of the Puzhehei karst landscape ecological protection comprised 11 core area patches with the landscape connectivity index of (dPC) ≥ 10, with a total area of 166.6572 km2, which constituted 46.06% of the total study area, and the ecological source area totaled 77.275 km2, or 21.36% of the total study area; (2) there were 78 potential ecological corridors in the Puzhehei karst region, with a total length of 545.186 km, including 12 key corridors and 66 general corridors; (3) a total of 51 ecological nodes were identified, including 11 “source-type ecological nodes”, 30 “ecological pinch points”, and 10 “ecological obstacles”, including 16 key ecological nodes. This study provides a theoretical basis for the integration of Puzhehei Nature Reserve, as well as a reference for the ecologically sustainable development of similar karst areas.

The impact of residential villages on the nontuberculous mycobacteria (NTM) in streams flowing through them has not been studied in detail. Water and sediments of streams are highly susceptible to anthropogenic inputs such as surface water flows. This study investigated the impact of 7 residential villages in a karst watershed on the prevalence and species spectrum of NTM in water and sediments. Higher NTM species diversity (i.e., 19 out of 28 detected) was recorded downstream of the villages and wastewater treatment plants (WWTPs) compared to sampling sites upstream (i.e., 5). Significantly higher pH and Zn concentration were detected in sediments inside the village and downstream of the WWTP’s effluents. P and Cu sediment concentrations were higher only downstream of WWTPs compared to sediments inside the settlement. The effluent from the WWTPs had a substantial impact on water quality parameters with significant increases in total N, P, anions (HCO3–, Cl–, N-NO3–, and N-NH3–), and cations (Na+ and K+). The results provide insights into NTM numbers and species diversity distribution in a karst watershed and the impact of urban areas. Although in this report the focus is on the NTM, it is likely that other water and sediment microbes will be influenced as well.
