in this study, water samples were collected from 10 thermal and non-thermal springs of mahalat setting during four periods in 2011. the discharge rates of these springs vary from 2 l/s to 45 l/s and their temperature range from an average minimum of 18oc to maximum 47oc. spring water is high in so4-cl and this is related to gypsum dissolution. correlation coefficient, principal component analys...
Elevated stream temperature is a primary factor limiting the coho salmon (Oncorhynchus kisutch) population in California’s Shasta River Basin. Understanding the mechanisms driving spatial and temporal trends in water temperature throughout the Shasta River is critical to prioritising river restoration efforts aimed at protecting this threatened species. During the summer, the majority of stream...
Temporal variation in geochemistry can cause changes in microbial community structure and diversity. Here we studied temporal changes of microbial communities in Tengchong hot springs of Yunnan Province, China in response to geochemical variations by using microbial and geochemical data collected in January, June and August of 2011. Greater temporal variations were observed in individual taxa t...
