Lake Xochimilco, in a detail from the 1847 Bruff/Disturnell map The Valley of Mexico at the time of the Spanish conquest, c. 1519. Lake Xochimilco (Spanish pronunciation: [sotʃiˈmilko]; Nahuatl languages: Xōchimīlco, pronounced [ʃoːtʃiˈmiːlko] listen ⓘ) is an ancient endorheic lake, located in the present-day Borough of Xochimilco in southern Mexico City.
As described by Paine in 1966, some sea stars (e.g., Pisaster ochraceus) may prey on sea urchins, mussels, and other shellfish that have no other natural predators. [19] If the sea star is removed from the ecosystem, the mussel population explodes uncontrollably, driving out most other species. [4] These creatures need not be apex predators.
An apex predator, also known as a top predator or superpredator, is a predator [a] at the top of a food chain, without natural predators of its own. [ 6 ] [ 7 ] Apex predators are usually defined in terms of trophic dynamics , meaning that they occupy the highest trophic levels .
True monitors are most well known by their maximum size, but what really distinguishes them from other monitors is their great evolutionary potential to kill large prey in relation to their own body size, allowing them to occupy the niche of apex predators in most of their biomes.

“They are the only group of birds that achieved the role of terrestrial apex predators, evolving species that basically conquered South America during the Miocene (about 23.03 million to 5.33 ...
When populations of an apex predator decrease, populations of mesopredators in the area often increase due to decreased competition and conflict with the apex predator. [2] This is known as the mesopredator release effect, which refers to the release of mesopredators from the trophic cascade. [5]
