pH is an important factor that shapes the structure of bacterial communities. However, we have very limited information about the patterns and processes by which overall bacterioplankton communities assemble across wide pH gradients in natural freshwater lakes. Here, we used pyrosequencing to analyze the bacterioplankton communities in 25 discrete freshwater lakes in Denmark with pH levels ranging from 3.

- Shallow lakes can exist in two stable states: a clear-water state dominated by submerged plants or a turbid state overwhelming with phytoplankton; however, clear-water can also occur without these plants.
- A model was created to study how sediment algae influence this shift from turbid to clear-water states in a lake after fish removal, finding that algae can impact phosphorus levels and affect the production between periphyton and phytoplankton.
- The model indicated that the lake's response to changes in phosphorus levels and fish removal is influenced by its physical structure, and that the ability of periphyton to maintain clear-water conditions is sensitive to light and phosphorus interactions.
Climate change may have profound effects on phosphorus (P) transport in streams and on lake eutrophication. Phosphorus loading from land to streams is expected to increase in northern temperate coastal regions due to higher winter rainfall and to a decline in warm temperate and arid climates. Model results suggest a 3.
