The text describes how some recent and ongoing research does not support the wolf trophic cascade hypothesis. The "top-down" or "bottom-up" refers to the ecological pyramid describing trophic levels. Productivity can be defined for any trophic level or other group, and it may take units of either energy or biomass. Heterotrophs (or consumers) get organic molecules by eating other organisms or their by-products. return []; . }; Concept 45.1 The endocrine system and the nervous system act individually and together in regulating an animal's physiology. }); hike = function() {}; vertical-align: -0.1em !important; Here we explore an example (that of Steller's sea cow, Hydrodamalis gigas) that can help inform this hypothesis for Pleistocene extinctions.This particular case is intriguing and potentially informative because various aspects of the rise and fall of sea cows are reasonably well known; the final step in the sea cows' demise occurred just several hundred years ago, in the presence of modern . /*special for safari End*/ A keystone species is a species which has a disproportionately large effect on its natural environment relative to its abundance, a concept introduced in 1969 by the zoologist Robert T.
