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.Expert Answer.

OVERVIEW The short film Some Animals Are More Equal than Others: Trophic Cascades and Keystone Species opens by asking two fundamental questions in ecology: "What determines how many species live in a given place? Or how large can each population grow?"The 1995/1996 reintroduction of gray wolves (Canis lupus) into Yellowstone National Park after a 70 year absence has allowed for studies of tri-trophic cascades involving wolves, elk (Cervus elaphus), and plant species such as aspen (Populus tremuloides), cottonwoods (Populus spp.), and willows (Salix spp.).To investigate the …Some Animals are More Equal than Others: Trophic Cascades and Keystone Species 1.

Despite general agreement that species interactions will be affected by climate change (1, 2), surprisingly few studies have explored the ways in which climate-modified trophic cascades might affect ecosystem functioning (reviewed in ref. 3).Individual and population-level responses to altered climatic conditions could have cascading effects that either amplify or dampen the impacts of ...
The division of labor displayed in anaerobic metabolic cascades appears to be hard-wired in the biology of the participating microorganisms: for example, no known microbe can degrade complex biopolymers anaerobically and at the same time perform methanogenesis [39].However, recent experiments with synthetic communities or marine particles show that this trophic organization is not limited to ...

The Green World Hypothesis is now widely known as trophic cascade.The concept was championed by three ecologists Nelson Hairston, Frederick Smith and Lawrence Slobodkin (HSS hypothesis) in 1960. They suggested that predators keep herbivore populations in check by consuming them.James Estes and colleagues discovered that the kelp forest ecosystems of the North Pacific are regulated by the presence or absence of sea otters, which feed on sea urchins that consume kelp.
