From the Ted Talk by Greg Asner: Ecology from the air

Unscramble the Blue Letters


Technology can change our understanding of nature.

Take for example the case of lnois. For centuries, it's been said that female lions do all of the hunting out in the open savanna, and male lions do nothing until it's time for dnienr. You've hread this too, I can tell. Well recently, I led an airborne mapping campaign in the kuregr National Park in South Africa. Our colleagues put GPS tracking collars on male and female lions, and we mapped their huinntg behavior from the air. The lower left shwos a lion sizing up a herd of impala for a kill, and the right shows what I call the lion viewshed. That's how far the lion can see in all directions until his or her view is obstructed by vegetation. And what we found is that male lions are not the lazy hunters we thought them to be. They just use a different strategy. Whereas the female lions hunt out in the open snanvaa over long distances, usually during the day, male lions use an ambush strategy in desne vtoietgean, and often at night. This video shows the aautcl hunting viewsheds of male lions on the left and females on the right. Red and darker colors show more dense vegetation, and the wtihe are wide open spaces. And this is the viewshed right literally at the eye leevl of hunting male and fealme lions. All of a sudden, you get a very claer understanding of the very sopoky cnoitoidns under which male lions do their hunting.

Original Text


Technology can change our understanding of nature.

Take for example the case of lions. For centuries, it's been said that female lions do all of the hunting out in the open savanna, and male lions do nothing until it's time for dinner. You've heard this too, I can tell. Well recently, I led an airborne mapping campaign in the Kruger National Park in South Africa. Our colleagues put GPS tracking collars on male and female lions, and we mapped their hunting behavior from the air. The lower left shows a lion sizing up a herd of impala for a kill, and the right shows what I call the lion viewshed. That's how far the lion can see in all directions until his or her view is obstructed by vegetation. And what we found is that male lions are not the lazy hunters we thought them to be. They just use a different strategy. Whereas the female lions hunt out in the open savanna over long distances, usually during the day, male lions use an ambush strategy in dense vegetation, and often at night. This video shows the actual hunting viewsheds of male lions on the left and females on the right. Red and darker colors show more dense vegetation, and the white are wide open spaces. And this is the viewshed right literally at the eye level of hunting male and female lions. All of a sudden, you get a very clear understanding of the very spooky conditions under which male lions do their hunting.
