Earth.com: Dwarf hippos in Madagascar preferred forests
UC research highlights importance of forests on African island
Science writers highlighted the University of Cincinnati's insights into an extinct hippo that once roamed the island of Madagascar in Africa.
UC College of Arts and Sciences Professor Brooke Crowley led a team of researchers who used isotopic analysis to discover that extinct dwarf hippos were feeding on sedges and leaves in forests rather than on grass on open savanna like their mainland cousins today.
The findings suggest grasslands in Madagascar are a relatively recent change facilitated by people rather than a natural habitat sustained in part by hippos. The study was published in the journal Plants, People, Planet.
Earth.com noted that Malagasy hippos are far smaller than common hippos found on the mainland. They likely resembled pygmy hippos that likewise live in forests in West Africa.
Common hippos travel overland each night to graze on grass. Studies have found their foraging helps support grasslands, preventing the succession of other types of plants.
UC's study suggests that Malagasy hippos had little influence over grasslands found on the island today.
