Researchers used a handheld device that looks a little like a ray gun to record how plant leaves on different Alaskan mountains reflect light. And, it turns out, different populations of plants of the same species-- for instance, plants living on neighboring mountaintops-- reflect light differently, in ways that echo their genetic variation from each other.<br /><br />Credit: Lance Stasinski<br />Credit: Catherine Chan<br />Credit: Dawson White<br /><br />Research Paper: Reading light: leaf spectra capture fine-scale diversity of closely related, hybridizing arctic shrubs <a href="https://nph.onlinelibrary.wiley.com/doi/full/10.1111/nph.17731" target="_blank" rel="nofollow">https://nph.onlinelibrary.wiley.com/doi/full/10.1111/nph.17731</a><br /><br />News Source: <a href="https://www.eurekalert.org/news-releases/931764" target="_blank" rel="nofollow">https://www.eurekalert.org/news-releases/931764</a><br />...<br /><a href="https://www.youtube.com/watch?v=hOMS51UnesI" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=hOMS51UnesI</a>
