Abstract Periphyton plays an important functional role in shallow lakes and is sensitive to variation in nutrient availability and global warming. Understanding the responses of periphyton to changes in nutrient availability in contrasting warming scenarios can contribute to the development of more efficient techniques for the restoration of lakes in a

Trophic strategies of freshwater nanoflagellates under variable run‐off scenarios
Abstract Terrestrial run‐off is increasing in temperate lakes due to climate change and can lead to loading of colored dissolved organic matter (cDOM) and nutrients, thus reducing light availability and increasing carbon, nitrogen, and phosphorus. Run‐off events are highly irregular, resulting in temporal resource variability that may determine the ...

The investigation of phycobiliproteins in isolated heterocystous cyanobacteria from western Mazandaran [PDF]
Cyanobacteria are gram-negative photosynthetic organisms and one of the most successful groups of organisms this planet has ever seen. They include some of the first life forms to evolve on Earth.

An assessment of plankton populations, toxic cyanobacteria, and potential impact of introduced marine alewife (Alosa pseudoharengus) in Pawtuckaway Lake, New Hampshire [PDF]
A field study was conducted during the summer, 2005 to evaluate the lake water quality and planktonic communities in Pawtuckaway Lake, NH. Of special concern was the condition of the plankton populations since the lake had been subjected to introductions

Smaller phytoplankton size‐groups control the stoichiometry of the autotrophic community
Abstract In the marine environment, the prevailing paradigm is that larger organisms like diatoms are primary contributors to phytoplankton stoichiometry. Numerous studies investigated the stoichiometry of phytoplankton groups or total community but its dynamics among different size‐groups are not resolved.

Impact of copper and iron on growth and silicic acid uptake in two Southern Ocean diatoms
Abstract Copper (Cu) and iron (Fe) are vital micronutrients that influence diatom physiology, growth rate, and nutrient stoichiometry. This study examines the interactive effects of Cu and Fe on two Southern Ocean diatoms, Proboscia inermis and Chaetoceros flexuosus, cultured under varying Fe and Cu conditions.
