Abstract Based on a theoretical approach, Gascuel showed that trophic flow kinetics is a key characteristic of ecosystems’ functioning, partly determining their response to human disturbances such as fishing pressure. The kinetics quantifies the speed of the trophic flow, i.e., the velocity of biomass transfers from low to upper trophic levels, due to predation and/or ontogeny. In the present paper, we show that the production/biomass ( P / B ) ratio, used in many ecosystem models and… CONTINUE READING
