Heart disease is a leading killer of humans, so it should not be that big a surprise that it is also the leading killer of great apes. Just as we have worked to improve human heart health, the Great Ape Heart Project is making similar strides among great apes.

Detroit Zoo has introduced the new Devereaux Tiger Forest and welcomed Amur tigers Nikolai and Aleksei, 2-year-old brothers who were born at the Columbus Zoo. The habitat is also home to 16-year-old female Kisa, who was born at the Detroit Zoo. The renovated and expanded habitat was made possible in part by a $1-million gift from the Richard C. Devereaux Foundation. The $3.5-million habitat occupies 1 acre in the Detroit Zoo's Asian Forest across from the Holtzman Wildlife Foundation Red Panda Forest. The Amur tiger (Panthera tigris altaica), formerly known as the Siberian tiger, is the largest member of the big cat family and the largest of the five remaining subspecies of tiger.
