Newly published in Global Ecology and Biogeography, research by Alli Cramer, a 2020 doctoral graduate of WSU’s School of the Environment, now at the University of California Santa Cruz, and WSU Professor Stephen Katz revealed a new approach which sorts biomes based on their life-supporting potential and stability of the sea floor.
Cramer and Katz reviewed more than 130 studies to weigh variables such as light, depth, and nutrients across seven biomes incorporating dozens of environments, including coral reefs, kelp beds, ocean ice, and deep abyssal plains.
Analyzing the data inductively, rather than proceeding from an initial hypothesis, they found biomes were most clearly sorted by two strong variables: gross primary production, a measure of the energy in the food web; and substrate mobility, or the movement and composition of the ocean floor.
