What animal filled the role of top predator in yellowstone before wolves were reintroduced?
mixer [17]

Answer:

Explanation:

El Parque Nacional de Yellowstone (Estados Unidos), considerado el parque nacional más antiguo del mundo, fue creado en 1872 durante la presidencia de Ulysses S. Grant. En sus inicios, la fauna del parque no recibió la misma protección que hoy en día: los lobos y los pumas fueron eliminados deliberadamente en 1926 y, al cabo de unos años, la población de ciervos aumentó tanto que los administradores del parque reconocieron que los herbívoros estaban alterando la vegetación, por lo que se realizaron matanzas selectivas para controlar la población de dichos animales. Las matanzas selectivas terminaron a finales de los años 60 y la población de ciervos volvió a aumentar, por lo que finalmente se optó por reintroducir el lobo: 14 lobos de la provincia de Alberta (Canadá) fueron liberados en 1995 y otros 17 lobos canadienses en 1996. "La reintroducción del lobo (Canis lupus) en el Parque Nacional de Yellowstone es el experimento ecológico más celebrado de la historia", así comienza un estudio publicado en Journal of Mammalogy por Mark Boyce, de la Universidad de Alberta.
