"Lafferty et al. show that all forms of these relationships come down to fundamental consumer-resource interactions"

"Energy flow in Ecosystems"

Perspective piece in Science:

"All organisms in an ecosystem can be placed on a trophic level, depending on whether they are producers or consumers of energy within the food chain (see the photo). Ecologists have long debated what regulates the trophic structure and dynamics of ecosystems (1). This is important because trophic structure and dynamics regulate many of the goods and services that ecosystems provide to wildlife and humankind, such as the production of harvestable food and energy, carbon sequestration and modulation of climate change, and nutrient uptake and control of global biogeochemical cycles (2). A study by Hatton et al. on page 10.1126/science.aac6284 of this issue (3) and a recent report by Lafferty et al. (4) represent important advances toward a unified theory of trophic structure that captures observed trends across all ecosystems...."

"Could there be a unified theory of ecology?"

Coverage on Forbes:

"Scientists love unifying theories - a single equation (or set of equations) that explains everything in the discipline. Physicists have been searching for theirs for decades, running into difficulty unifying quantum theory with relativity. Economists work very hard at trying to model the global economy via complicated regression models. Until recently, however, ecologists thought that different food webs operated under distinct conditions. That is, the dynamics of foxes and squirrels must be different from those of parasites eating hosts...."
