Cascade (juggling) for a complete cycle of throws. However, in order to keep the number of props in the juggler's hands to a minimum, it is necessary to begin the pattern by throwing, from alternating hands, all but one prop (in the same hand as the first throw, which started with one more prop than the other) before any catches are made. The reverse cascade, or outside cascade, is a juggling pattern in which the props follow the same path as the cascade, but with time going backwards, hence the 'reverse'. One throws every ball with, "an outward instead of an inward
Trophic cascade debated how ubiquitous they are. Hairston, Smith and Slobodkin argued that terrestrial ecosystems, as a rule, behave as a three trophic level trophic cascade, which provoked immediate controversy. Some of the criticisms, both of Hairston, Smith and Slobodkin's model and of Oksanen's later model, were: Antagonistically, this principle is sometimes called the "trophic trickle". Although Hairston, Smith and Slobodkin formulated their argument in terms of terrestrial food chains, the earliest empirical demonstrations of trophic cascades came from marine and, especially, aquatic ecosystems. Some of the most famous examples are: The fact that the earliest documented trophic cascades all occurred in
