The ecology of fear and inverted biomass pyramids Malone

In inverted biomass pyramids (IBPs) prey are outnumbered by their predators when measured by biomass We investigate how prey should behave in the face of danger from higher predator biomass and how anti‐predator behavior (in the form of vigilance) can in turn affect the predator prey system

(PDF) On the prevalence and dynamics of inverted trophic

Elton (1927) was the first to suggest that trophic biomass pyramids should be bottom heavy meaning that the biomass of each consumer trophic level is less than that of its resource However researchers report a range of different shapes of biomass pyramids ranging from bottom heavy (also called traditional)

Keystone species Wikipedia

A classic keystone species is a predator that prevents a particular herbivorous species from eliminating dominant plant species If prey numbers are low keystone predators can be even less abundant and still be effective Yet without the predators the herbivorous prey would explode in numbers wipe out the dominant plants and dramatically

(PDF) The paradox of inverted biomass pyramids in kelp forest

Theory predicts that bottom heavy biomass pyramids or 'stacks' should predominate in real world communities if trophic level increases with body size (mean predator to prey mass ratio (PPMR) more than 1) However recent research suggests that inverted biomass pyramids (IBPs) characterize relatively pristine reef fish communities
