The Cryptic Nature of Trophic Downgrading The omnipresence of top-down control in ecosystems is not widely appreciated because several of its key components are difficult to observe. invasive specie    ... Estes JA, et al. STONY BROOK, NY–"Trophic Downgrading of Planet Earth," a review paper that will be published on July 15, 2011, in the journal Science, concludes that the decline of large predators and herbivores in all regions of the world is causing substantial changes to Earth’s terrestrial, freshwater, and marine ecosystems. Trophic downgrading of planet earth. Trophic downgrading of planet earth. This paper looks at how the loss of large apex consumers could affect trophic cascades and the potential consequences it could have on the dynamics of disease, wildfire, carbon sequestration, invasive species, and biogeochemical cycles.

Download. Until recently, large apex consumers were ubiquitous across the globe and had been for millions of years. Published. Although such losses are widely viewed as an ethical and aesthetic problem, recent research reveals extensive cascading effects of their disappearance in marine, terrestrial, and freshwater ecosystems worldwide. Removing those apex consumers produces what’s called “trophic downgrading,” which refers to the cascade of damage that can occur when an intact ecosystem is disrupted in such a … TROPHIC DOWNGRADING OF PLANET EARTH, SCIENCE.
