Document Summary
Lecture 1: orientation; species ranges and limiting factors. All columbines have extensions that go back behind the flower called nectar spurs and the plant secretes sugar water that piles up in the bottom of the spur. The blue one (aquilegia caerulea) is adapted for pollination by extremely long tongued hock-moths (day-flying moths that come to these flowers and push their tongues all the way down). The red one (aquilegia elegantula) is adapted for pollination by hummingbirds which also have a very long tongue but not as long and flexible as a hock-moth. The spurs of the red one are considerably stiffer. The red one and blue one are relatives. Definition of ecology => is the science of the distribution and abundance of organisms. The most fundamental aspect of ecology is that everything is patchy. Organisms are not spread neither evenly nor randomly across the world.
