News Finding: The scientists were able to confirm the value of their method using a large dataset of 220,000 interactions from 290 food webs.
Paper Finding: The varying body-mass ratios limit which trophic interactions are realized in a community , and the strength of these interactions .
News Context: These data enable researchers to determine the structure and stability of a habitat, without the need for a comprehensive examination of the relationships to other organisms. The scientists were able to confirm the value of their method using a large dataset of 220,000 interactions from 290 food webs. "If there is a big difference, this has a positive effect on the equilibrium of the energy flows of the food web and, by extension, on the stability of the ecosystem."
Paper Context: The varying body-mass ratios limit which trophic interactions are realized in a community , and the strength of these interactions . Predators typically exert the strongest feeding pressure on prey that are 1-2 orders of magnitude smaller 1 , while weaker interaction strengths are realized with prey that are smaller or larger than this size 11 . Moreover, they also buffer natural communities against perturbations from global warming
