Examples of trophic in a Sentence

Recent Examples on the Web: Adjective

The effect is known as a trophic cascade, in which the removal of a key species has ripple effects throughout the ecosystem. Steve Winter, National Geographic, "How City-Dwelling Leopards Improve Human Health," 9 Mar. 2018 There has been a lot of research done on how removing predators can cause a trophic cascade that can result in a collapse of a system. Jacqueline Cutler, USA TODAY, "Why the cheetah population is shrinking," 12 Dec. 2017 This is, in effect, a trophic shift—the length of the species’ food chain has changed. Wendy Mitman Clarke, Smithsonian, "Bones of the Hawaiian Petrel Open Up a Window Into the Birds’ Changing Diet," 26 Apr. 2017 This shift has created a trophic mismatch, meaning plants bloom earlier, and insects that eat the plants emerge earlier, while the red knot chicks that eat the insects are hatching too late to feed on them at their peak. National Geographic, "Arctic Warming Is Shrinking This Adorable Shorebird," 12 May 2016 This indicated that the birds’ food chain had become shorter; somewhere in the birds’ food chain, animals were eating at a lower trophic level. Wendy Mitman Clarke, Smithsonian, "Bones of the Hawaiian Petrel Open Up a Window Into the Birds’ Changing Diet," 26 Apr. 2017 Their gradual reestablishment triggered a trophic cascade much like the reintroduction of the Yellowstone wolves had, but for different reasons. Brian Switek, WIRED, "Restoring Missing Lynx – The Rejuvenation of an Ecosystem," 14 June 2010 Some experts, however, aren’t so sure that a trophic cascade is at work here. Brigit Katz, Smithsonian, "Is Australia’s Dingo-Proof Fence Changing the Ecosystem of the Outback?," 15 May 2017 But normally, these records only cover two trophic levels. National Geographic, "Amazing ‘Nesting Doll’ Fossil Reveals Bug in Lizard in Snake," 7 Sep. 2016
