A team of Princeton ecologists took advantage of a rare opportunity to study what happens to an ecosystem when large carnivores are wiped out. “Large carnivores play a critical, and disproportionate, role in their ecosystems, and their populations are declining worldwide,” said Justine Atkins, a graduate student in ecology and evolutionary biology at Princeton. “However,…
Language, music, and art often vary between adjacent groups of people, and help us identify not only ourselves but also others. And in recent years rich debates have emerged and spawned research into culture in non-human animals. Scientists first observed chimpanzees using tools more than half a century ago. As this complex behaviour appeared to…
Pangolins, a group of unique African and Asian scaly mammals, are considered to be one of the most heavily trafficked wild mammals in the world. They are hunted and traded for their meat, scales, and other body parts, and used as traditional medicines in parts of Africa and Asia. Of the eight pangolin species, four…
In 1991, a strange thing happened in the wilds of Tanzania’s Serengeti National Park. The Serengeti, a World Heritage Site, is home to a spectacular range of carnivores, from lions to cheetahs and more. And with more than 1.5 million zebras, wildebeests and gazelles making annual migrations across the park, there’s plenty of food for…
A new review paper finds that the loss of Africa’s forest elephants has broad impacts on their ecosystems, including hitting several tall tree species, which play a key role in sequestering carbon dioxide. Forest elephants disperse large seeds, keep the forest canopy open, and spread rare nutrients across the forest, benefiting numerous species across the…
Mention wildlife on Madagascar and the first thing listeners probably picture is the island’s famed lemurs. As many people know, these unique primates are found nowhere else, and are the most endangered group of mammals in the world. But few people realize that lemurs’ fate is directly bound up with that of Madagascar’s largest predator,…
At current rates of loss to poaching, rhino species will be extinct within our lifetimes. The big problem is demand for their horn from Asia. The market for rhino horn is moving from “traditional” medicine to “investment value” as jewellery and other processed artefacts in the art and antiques market, according to wildlife trade monitors…
Beehive fences can help improve human-elephant coexistence. By Katarzyna Nowak, University of the Free State When people cultivate food crops on or near wild lands it can be assumed that wild animals will eat them – what’s known as crop-raiding. Farms in the vicinity of protected areas can expect to be visited by a range…
A study of the microbiomes of wild gorillas and chimpanzees offers insights into the evolution of the human microbiome and might even have implications for human health. The research project was led by scientists at the Center for Infection and Immunity (CII) at Columbia University’s Mailman School of Public Health. Findings appear in the journal Nature…
Malawi Parliament last month passed new regulations that place an additional 216 species under protection. The regulations form a critical secondary law to the National Parks and Wildlife Act (NPWA), which came into effect in 2017, and which most notably increased the maximum penalty for wildlife crime to up to 30 years in prison. Illegal…
