How does anthropogenic activity affect the population of anaerobic micro-organisms in hot springs?5 answersAnthropogenic activities, such as capping and diverting springs for recreational use, can impact the microbial populations in hot springs. Studies in Hot Springs National Park (HSNP) and Yellowstone National Park (YNP) show that human modifications may alter the structure of bacterial communities in these thermal systems. In HSNP, despite anthropogenic changes, the microbial diversity remains considerable, with potentially unique species present in the springs. Additionally, in YNP, changes in microbial populations over time were observed in flowing springs due to human cross-contamination concerns, highlighting the need for proper sampling protocols to preserve these ecosystems for future research. These findings suggest that anthropogenic activities can influence the composition and diversity of anaerobic microorganisms in hot springs.
