Research with implications for species under stress from a warming planet — ScienceDaily

For many marine animals, such as the Dungeness crab, seasons and timing are components of complex life cycles, where disturbances can have serious effects on populations. Understanding how climate change affects each stage of life is no small task when considering all the variables and moving parts of a changing environment. Despite these challenges, this … Read more

A new method for predicting the response of ecosystems to marine heatwaves developed by international collaboration — ScienceDaily

Marine heat waves, driven by climate change, are becoming more frequent and intense around the world. Although we know that heat waves kill marine organisms and have devastating effects on ecosystems, there is currently no way to predict these effects or help ecosystems adapt. An international team of marine scientists from Hong Kong, Japan, and … Read more
