Under normal cellular conditions there is a constant balancing act between the creation of reactive oxygen species (ROS) and their elimination by the antioxidant system including enzymes such as superoxide dismutase, glutathione peroxidase, and catalase. Abnormally low levels of ROS can impede cellular signaling and some normal intracellular reactions, while overly high levels of ROS create oxidative stress which can lead to the improper oxidation of lipids, proteins and DNA resulting eventually resulting in apoptosis, necrosis, and other cellular damage.… » Read More

Stress and mineralization responses to environmental stress in Mantis Shrimp
Calcified marine organisms face a double edged sword as global warming increases not only the temperature of ocean waters, but also the level of acidification. Many such organisms that live within the intertidal zone are already adapted to cope with the broad fluctuations in temperature and pH that occur with each tidal cycle – but precisely how the species cope with the stressors of increased temperature and decreased pH varies widely and have costs that can include increased energy demands, growth restriction, physiological stress, and changes in mineralization. … » Read More
Changes in the length of day throughout the year can be a marker for critical species functions such as migration, hibernation, and mating.
