Diverse fish communities more productive and resistant to changing temperatures

Fish provide protein to billions of people and are an especially critical food source in the developing world. Today marine biologists confirmed a key factor that could help them thrive through the coming decades: biodiversity. Communities with more fish species are more productive and more resilient to rising temperatures and temperature swings, according to a new study from the Smithsonian's Tennenbaum Marine Observatories Network and other international institutions.
