Leading indicators of trophic cascades.

Regime shifts are large, long-lasting changes in ecosystems. They are often hard to predict but may have leading indicators which are detectable in advance. Potential leading indicators include wider swings in dynamics of key ecosystem variables,…

This paper examines the empirical evidence on currency crises and proposes a specific early warning system. This system involves monitoring the evolution of several indicators that tend to exhibit an unusual behavior in the periods preceding a…

This paper examines whether financial disclosures on acquired entities allow investors to effectively predict goodwill impairment, a task that has become more important following the recent abolishment of goodwill amortization. In predicting…

Since its first appearance (Hairston, Smith & Slobodkin, 1960), the hypothesis that predation can structure communities has courted controversy (Shapiro, Lamarra & Lynch, 1975; Strong, 1992; McCann, Hastings & Strong, 1998). Nearly 50 years later…

Although trophic cascades (indirect effects of predators on plants via herbivores) occur in a wide variety of food webs, the magnitudes of their effects are often quite variable. We compared the responses of herbivore and plant communities to…

Predation can be intense, creating strong direct and indirect effects throughout food webs. In addition, ecologists increasingly recognize that fluxes of organisms across ecosystem boundaries can have major consequences for community dynamics.…

Trophic cascades in ecological communities are defined as the vertical propagation of indirect mutualism between non-adjacent trophic levels in a food chain or food web.
