Animals Deserve to Be Included in Global Carbon Cycle Models, Too

by Nathaniel Scharping 16 April 202416 April 2024

Because they are far less plentiful than plants and microbes, animals have typically been excluded from examinations of carbon exchange in the atmosphere. But new research shows they may have a considerable influence on carbon cycle dynamics.
