The effects of ocean warming and acidification on seaweed growth and urchin grazing

Forward: This thesis shows that purple urchins increase feeding rates by about 500% when exposed to acidified conditions that are currently occurring in Northern California during spring upwelling season. (see figure 8 below) http://broncoscholar.library.cpp.edu/bitstream/handle/10211.3/194019/BriggsLauren_Thesis2017.pdf?sequence=4 No wonder the kelp is all gone! Of course 150 purples per square meter can do

Decreased pH and increased temperatures affect young-of-the-year red king crab (Paralithodes camtschaticus)

June 28, 2017   The red king crab (Paralithodes camtschaticus) is a high-latitude commercially important species with a complex life-history cycle which encompasses a wide variety of conditions and habitats. High-latitude waters, including those around Alaska where red king crab live, are predicted to have increased ocean acidification and temperatures
