insert_link Environment Venomous snakes could start migrating in large numbers if we hit 5ºC warming By Pablo Ariel Martinez, Universidade Federal de Sergipe A global group of scientists has predicted that climate change may cause dramatic movements in venomous snake populations across many countries in Africa. The scientists took into account climate change predictions about changes to the current habitats of 209 venomous snakes, and mapped where those environments were found elsewhere. Based on this, they predict that snakes were likely to migrate […] today28 March, 2024
insert_link Africa We built an AI tool to help set priorities for conservation in Madagascar: what we found By Daniele Silvestro, University of Fribourg Artificial Intelligence (AI) – models that process large and diverse datasets and make predictions from them – can have many uses in nature conservation, such as remote monitoring (like the use of camera traps to study animals or plants) or data analysis. Some of these are controversial because AI can be trained to be biased, but others are valuable research tools. […] today27 March, 2024

insert_link Africa Pangolins in Africa: expert unpacks why millions have been traded illegally and what can be done about it By Olajumoke Morenikeji, University of Ibadan Pangolins are fascinating creatures known for their unique appearance and distinctive scales. They are mammals belonging to the order Pholidota and are native to Africa and Asia. Due to their primary diet of ants and termites, pangolins are often referred to as “scaly anteaters”. The African pangolin species are dispersed throughout southern, western, central and east Africa. Pangolins face rapid […] today22 March, 2024
insert_link Africa New ecoregion proposed for Southern Africa’s threatened ‘sky islands’ By Ryan Truscott There is an “inland archipelago” of mountains stretching across southern Malawi and northern Mozambique — a chain of hard granite inselbergs lifted high above the surrounding landscape as it weathered down over millions of years. These “sky islands”, as they’re also known, are topped with high-altitude grasslands and evergreen forests and watered by cool moist winds from the Indian Ocean to the east. A group […] today18 March, 2024

By Liz Kimbrough via Mongabay “We did it!” Doka Nason shouted as he stared at the screen of a camera trap in Papua New Guinea. He and his team had just captured a long-sought image: that of the black-naped pheasant-pigeon (Otidiphaps nobilis insularis). Believed to be extinct, this rare ground-dwelling bird was photographed as part of […] today28 February, 2024

When the family had arrived to the Amazon from southern Brazil four decades earlier, her father had swiftly cleared the dense rainforest to make way for pasture. “He razed it all by hand, with a saw and an ax,” Souza […] today20 February, 2024
insert_link Environment Rhinos can’t sweat, making them vulnerable to overheating: global warming could wipe them out in southern Africa By Timothy Randhir, UMass Amherst Southern Africa is home to 22,137 of the world’s 23,432 white and black African rhinos. But they’re facing grave threats because of a warming planet. Now, the first study of how climate change affects rhinos in southern Africa has found that they will cease to exist in the region’s national parks by 2085 if the world takes the worst-case scenario climate change […] today16 February, 2024
insert_link Africa Morocco dinosaur discovery gives clues on why they went extinct By Nicholas R. Longrich, University of Bath 66 million years ago, the last dinosaurs vanished from Earth. We’re still trying to understand why. New fossils of abelisaurs – distant relatives of the tyrannosaurs – from north Africa suggest that African dinosaurs remained diverse up to the very end. And that suggests their demise came suddenly, with the impact of a giant asteroid. The causes of the mass […] today13 February, 2024
