Abstract

Resilience of eight laboratory stream ecosystems was evaluated following a 92-d light elimination disturbance. Results are consistent with the theory that resilience is positively associated with the rate of nutrient input to a nutrient-limited system, but are inconsistent with the idea that resilience is positively associated with the addition of a herbivore trophic level to the system. Grazing intensity (density), as well as behavioural (vagility) and life history characteristics may need to be considered. -from Authors
