If you could turn back the clock about 200 years, you could watch as millions of whales swam along their migration routes. Around 150 years ago, you could witness bison…
African elephants use areas of grassland, bushland, and woodland, but how do they move through these different vegetation types in different seasons, especially where water becomes a seasonally scarce resource?…
Small animals form the majority of animal diversity on Earth, but there are fundamental gaps in our knowledge of how animals too small to wear GPS or satellite tracking tags…
The millions of waterbirds that migrate each spring from South America to as far as the Arctic can’t do it in one trip. They stop to rest and refuel several…
Data from satellite tracking tags deployed on elephants in Botswana, Namibia, Zambia and along the border of Angola and Zimbabwe have revealed that the Kavango Zambezi Transfrontier Conservation Area (KAZA…
