DaveO Posted October 19, 2019 Share Posted October 19, 2019 I found a reference to this work while reading Australian Birdlife magazine - a clear example of serendipity Avian UV vision enhances leaf surface contrasts in forest environmentshttps://www.nature.com/articles/s41467-018-08142-5 It comes with the usual warning about making your head hurt Dave Link to comment
dabateman Posted October 20, 2019 Share Posted October 20, 2019 Interesting, was a long article to just say less uv passes through the leaves than green light. Thus the reflected UV light difference is used for contrast vision of the birds. Link to comment
DaveO Posted October 22, 2019 Author Share Posted October 22, 2019 I'm only a chemist, but it often seems to me as if many papers in this area are answers searching for questions. Dave Link to comment
Andrea B. Posted November 8, 2019 Share Posted November 8, 2019 That's how mathematics is sometimes done! The theory ("answers") progresse beyond the practical applications ("questions") of it. Yet eventually, it seems, the theory explains something somewhere in physics/engineering/etc. This is an interesting paper, Dave. I read a lot of it, then got a bit bogged down. (But that's ok.) Speaking of bird vision. This is just being discussed today here: https://www.ultravioletphotography.com/content/index.php/topic/3561-hello-again-and-berry-question/ Link to comment
