Summary

Ecological changes generate a wide-open array of stress conditions in aquatic animals and photosynthetic organisms. These environmental modifications could be due to intrinsic biotic (e.g. biotoxins presence, sexual maturation, food quality, etc.) and/or abiotic (such as temperature, salinity, acidification, solar and UV radiation, tides, seasonality, etc.) factors. Even more, water bodies and oceans properties may fluctuate according to anthropological incidence such as pollution (e.g., metals), industrial and urban wastes, climate global change, etc. This scenario often promotes an induction of disbalance between the generation and elimination of reactive oxygen species (ROS) and reactive nitrosative species (RNS) in living organisms. Their production in cellular and extracellular systems has to be tightly controlled by antioxidants and radical scavenging biochemical reactions. The importance of radical species generation and the modification in their steady state concentration by alteration of either environmental or metabolic conditions, due to either natural or anthropogenic factors, and the effect on the cellular signaling and the maintenance of the homeostatic conditions in photosynthetic and non-photosynthetic organisms will be relevant contributions to this special issue.

 

This topic focuses on the frontiers in the knowledge on cellular mechanics and the advances in oxidative and nitrosative stress in aquatic organisms. Studies facing different levels of natural organization, such as molecular, cellular, physiological and ecological aspects are encouraged to be submitted.

 

We welcome biologists, biochemists, biophysics, physicists, and ecological researchers to contribute original articles and reviews (or mini-reviews) to this special issue.
