I break ...Trophic Cascade Theory and Apex Predators. There have been several attempts to come up with a proper definition for the term trophic cascade and its theory. Still, it refers to 'the interaction of different intermediary species via an indirect manner, spreading downward in a top-down forcing through food web that originated with predators.'A trophic cascade is a phenomenon where species impact other species even if there are no direct interactions among them. For example, Dr. Jim Estes showed that sea otters control the population of sea urchins, which eat kelp. Thus, the otter indirectly affect the amount of kelp and impact all the species that depend on kelp.New studies are documenting trophic cascades in theoretically unlikely systems such as tropical forests and the open ocean. Together with increasing evidence of cascades, there is a deepening understanding of the conditions that promote and inhibit the transmission of predatory effects. These conditions include the relative productivity of ecosystems, presence of refuges and the potential for ...THE TROPHIC CASCADE HYPOTHESIS In 1979, Paine combined his own results with those of others, including Estes and Palmisano, to propose the idea of trophic cascades, in which direct and indirect effects from a species at or near the top of the food chain propagate down and regulate the species and population sizes in the rest of the community.
This activity explores the content and research discussed in the film Some Animals are More Equal than Others, which tells the story of the ecologists who first documented the role of keystone species in ecosystem regulation.

In this Data Point activity, students explore a new trophic cascade example by interpreting a graph to examine how the disappearance of cougars affected the trees in Zion National Park. To use this resource as part of this playlist: Have students analyze the graph and background reading in the “Student Handout.”The ratio of predator-to-prey biomass is a key element of trophic structure that is typically investigated from a food chain perspective, ignoring channels of energy transfer (e.g. omnivory) that ...A trophic cascade occurs when predators indirectly affect the abundance of organisms more than two trophic levels down (Figure 1). The otter-urchin-kelp interaction is an example of a trophic cascade.The top-down effect refers to a higher trophic level influences the community structure of a lower trophic level through predation [10]. What is a cascade species? An ecological cascade effect is a series of secondary extinctions that are triggered by the primary extinction of a key species in an ecosystem.View Trophic_Cascade_Guide from BSC BCH1010 at Palm Beach State College.

The authors review the factors affecting cascade strength and how these vary between systems.
Trophic cascades in ecological communities are defined as the propagation of indirect effects between nonadjacent trophic levels in a food chain or food web. Typically, cascades are driven by predation from the top-down, with altered herbivore densities mediating the ultimate effects on the biomass of primary producers. ... Key Concepts ...Furthermore, fish trophic levels can modify the strength of trophic cascades, but an even number of food chain length does not have a negative effect on primary producers in real ecosystems.
