And now a new class of adaptable mesopredators are remaking the ecosystems they take over.

Trophic Level: A hierarchical level in an ecosystem made up of organisms that share the same function in the food web.  Apex predator: The animals at the top trophic level that feed on animals and organisms below them. Mesopredator: A member of a mid-ranking trophic level that preys on animals and organisms in lower trophic levels and occasionally gets eat by apex predators. Mesopredator Release: An ecological phenomenon in which mesopredators rapidly grow in population once apex predators are removed from an ecosystem.  Trophic Cascade: A series of dramatic changes in an ecosystem often triggered by mesopredator release.  ___________________________________________  If you liked this week’s video, you might also like:  ScienceWithTom goes deep on the science in this video with ecologist Alex McInturff: https://youtu.be/TJcgtqjj-yo _________________________________________  Subscribe to MinuteEarth on YouTube: http://goo.gl/EpIDGd Support us on Patreon: https://goo.gl/ZVgLQZ And visit our website: https://www.minuteearth.com/  Say hello on Facebook: http://goo.gl/FpAvo6 And Twitter: http://goo.gl/Y1aWVC  And download our videos on itunes:  https://goo.gl/sfwS6n ___________________________________________  Credits: Script Writer: Tom McFadden Script Editor: David Goldenberg Video Illustrator: Qingyang Chen Video Director: David Goldenberg, Emily Elert Video Narrator: Emily Elert, Tom McFadden With Contributions From: Henry Reich, Alex Reich, Kate Yoshida, Ever Salazar, Emily Elert, Peter Reich  Music by: Nathaniel Schroeder: http://www.soundcloud.com/drschroeder  ___________________________________________  References:  Darimont, C., Fox, C., Bryan, H., and Reimchen, C.
