Sorry to take so long to find this comm...Hi Kelvin,<br />Sorry to take so long to find this comment. It's a good question. What we meant is that sagrei's spread to the islands wasn't biased in some way by differences in carolinensis morphology or habitat use across populations. In other words, maybe sagrei is on the islands it's on because carolinensis were perching higher and had larger toepads before the invasion on those very islands. Thus, sagrei and carolinensis were able to coexist there, but not on the islands with just carolinensis, where they perch lower. The genetic data support that each island population of carolinensis is evolving independently and observational/experimental data support that sagrei colonizes every island it reaches. This suggests that there weren't any pre-existing differences among carolinensis populations and that character displacement is evolving in situ on every island that sagrei is reaching, rather than being an outcome of ecological sorting or a single evolutionary event. Hope that helps. Thanks for the question and the kind words! - YoelYoelhttps://www.blogger.com/profile/08564518519673106894noreply@blogger.comtag:blogger.com,1999:blog-4456348657596914237.post-32254104716581520502014-10-30T23:33:47.370-04:002014-10-30T23:33:47.370-04:00Hi Yoel, great work!

Doesn't the presence of both lizard species preclude competitive exclusion? This is fascinating work.<br /><br />KelvinAnonymoushttps://www.blogger.com/profile/05522043472341488706noreply@blogger.comtag:blogger.com,1999:blog-4456348657596914237.post-62424716849246107852014-10-30T20:57:44.474-04:002014-10-30T20:57:44.474-04:00super cool!
