why are jaguars considered a keystone species

Umbrella species have large habitat needs, and the requirements of that habitat impact many other species living there. None of these are true about a keystone species. Even though these vital species differ according to their environment, they all have one aspect in common. They also provide a safe haven and feeding area for small fish among their roots, which reach down through the shallow water.

Among the many keystone species that are vulnerable or already endangered is the jaguar (Panthera onca). There was once a time when the Jaguar roamed the length of a biological corridor that stretched from the Southwestern United States all the way to Argentine Patagonia. \\ A foundation species exerts the most influence on maintaining biodiversity while a keystone species is most abundant. Sea Otters are considered keystone species because of their ability to exert a trophic cascade or in other words top down pressure.
