Four jaguar captures, three deaths

Octavio Rosas, a doctoral student at New Mexico State University, had set out snares in an area near Nacori Chico in the Sierra Madre mountains of eastern Sonora. Early that warm morning, he and another biologist found a jaguar trapped in one of their leg snares. The jaguar lunged at the pair, but they were able to get a dart loaded with the sedative ketamine into its hindquarters. When the first dart didn't sedate the animal, Rosas applied two more doses, half the quantity of the first. The animal never recovered from sedation and died as the warm morning turned hot. Rosas attributed the death to "heat stress."...ArizonaStar
