Consumer resilience suppresses the recovery of overgrazed ecosystems
Abstract Many heterotroph species perish when faced with severe food limitation; others can persist, adapt, and thrive. Sea urchins are emblematic of this paradox: they can overgraze kelp forests to form barren habitats, but can then survive for decades in these nutritionally depauperate seascapes.

Kaptai Lake is a developing ecosystem with a linear food web and thereby vulnerable to external influences. The apex predator, Catfish (TL‐3.364), occupied the top trophic niches, while the overabundant (B: 3.264 t/km2) Clupeid (TL‐2.56) dominated the lower trophic level in the food web. The higher values of ecotrophic efficiency for most of the groups
