Nitrogen addition effect overrides warming effect on dissolved CO and phytoplankton structure in shallow lakes.

Shallow lakes are numerous in all climate zones, but our knowledge about their dissolved carbon dioxide (CO) response to future climate change and nutrient enrichment is rather limited. Here we performed a mesocosm experiment with four treatments to investigate how warming and nitrogen addition will impact the partial pressure of CO (pCO) and phytoplankton community individually and combined. We found that warming alone had no significant effect on pCO, while nitrogen addition increased pCO significantly.

Application of microalgae enhances water quality in rice-crayfish culture.

Improper management of aquatic environments substantially restricts the development of the aquaculture industry. The industrialisation of the crayfish , for example, is currently being limited by poor water quality. Research suggests that microalgal biotechnology has a great potential for water quality regulation.

Transcriptomic and Physiological Responses to Oxidative Stress in a Glutathione Peroxidase Mutant.

Aerobic photosynthetic organisms such as algae produce reactive oxygen species (ROS) as by-products of metabolism. ROS damage biomolecules such as proteins and lipids in cells, but also act as signaling molecules. The mechanisms that maintain the metabolic balance in aerobic photosynthetic organisms and how the cells specifically respond to different levels of ROS are unclear.
