Ecology Letters, Volume 25, Issue 11, Page 2476-2488, November 2022., 2022
We predict that food webs with scale‐free degree distributions should be favourably selected by random disturbances (in regions less disturbed by human pressure) while food webs with random degree distributions would be associated with targeted disturbances (in areas with more human pressure).
