Warming impairs trophic transfer efficiency in a long-term field experiment

In ecosystems, the efficiency of energy transfer from resources to consumers determines the biomass structure of food webs. As a general rule, about 10% of the energy produced in one trophic level makes it up to the next. Recent theory suggests that this energy transfer could be further constrained if rising temperatures increase metabolic growth costs, although experimental confirmation in whole ecosystems is lacking. Here we quantify...

Embracing general theory and taxon-level idiosyncrasies to explain nutrient recycling

At the molecular level, the process of living involves coupled biochemical reactions that result in the uptake and transformation of energy and materials by an organism, yielding biomass to support its growth and reproduction, along with waste products.
