Webhypothesis is a modification of the ERH, and will therefore be referred to here as the Resource-Enemy Release Hypothesis (R-ERH). For the R-ERH to hold, two conditions must be met: (i) stronger enemy regulation of high- than low-resource species; and (ii) enemy release of exotic species (Fig. 1). The objectives of this review WebEnemy release hypothesis completely explains the success of invasive species. Invasive species disrupt a native ecosystem function or economy. All of these statements are true. The length of a phylogenetic tree is determined by: The amount of time since individual lineages diverged. The fossil record of the lineages considered.
