Posted by External 12 days ago General
http://feeds.sciencedaily.com — A study of the migratory biology of bar-headed geese, during their high altitude flights across the Tibetan plateau and Himalayan Mountains, has revealed how these birds cope with flying in the relatively low-density mountain atmosphere. The study shows that the geese perform a 'roller coaster' ride through the mountains, tracking the underlying terrain even if this means repeatedly shedding hard Read More

Why lizards have bird breath: Iguanas evolved one-way lungs surprisingly like those of birds

Posted by External 72 days ago General
http://feeds.sciencedaily.com — Biologists long assumed that one-way air flow was a special adaptation in birds driven by the intense energy demands of flight. But now scientists have shown that bird-like breathing also developed in green iguanas – reptiles not known for high-capacity aerobic fitness. The finding bolsters the case that unidirectional bird-like flow evolved long before the first birds. Read More
