Sub-lethal temperature effects are also related to metabolic inefficiencies, susceptibility to disease and toxic effects of pollutants, behavioural patterns, intra-and inter-specific competition, predator-prey relationships, community composition and parasite-host relationships.emperature reductions to stream environments in winter may result from the loss of insulation of the forest canopy under clear-cut conditions in combination with increased radiant cooling; accelerated freezing may lead to anchor ice formation and minimize interstitial habitat for juvenile fish (Hicks et al.
If your urinary pH fluctuates between 6 to 6.5 in the morning and 6.5 and 7 in the evening, your body is within a healthy pH range. First morning urine should be slightly more acidic as you eliminate waste accumulated throughout the night.
Primary causes may be kidney stones, certain medications or infection. Generally, the normal pH range for urine is between 4.6 to 8.0, although it may vary depending on the laboratory testing your urine. If you exhibit a low pH level of less than 4.6, this may indicate diabetic ketoacidosis, diarrhea or starvation.
