Than...Anon- had no idea of the wildflower festival. Thanks so much for the info- I’ll plan to be up there! Still searching for the guide- if you have a pointer, I’d appreciate it.<br /><br />KB- Short answer: Plants shifted range, both latitude and altitude in response to glaciations. For example, 18-20,000 years ago sagebrush grew where over much of Arizona where Creosote grows today, and everything from Bristlecone Pines to Joshua Trees grew much lower than they do today.<br /><br />Long answer: What we refer to as the “ice age” is the series of several glacial/ interglacials over the last million years or so, by which time probably most/all of the modern Roseaceae genera- and many species- probably existed in pretty much their present form. Doubtless many Rosaceae species shifted range, others went extinct, and others gave rise to new species, through environmental pressures, geographic isolation (such as glacial refugia, or islands formed by rising sea levels during interglacials) or even hybridization with other species in the family whose ranges overlapped due to changing climate conditions (Pyrus- the genus of pears & apples- has long been suspected of hybrid origin.)<br /><br />The proto-rose would have lived long before this, more like 50-60 million years ago. But it and its various descendants would’ve faced all kinds of crazy climate swings in the time since, such as the hot-house conditions that existed around 35-40 million years ago, when jungles grew in the Yukon.<br /><br />So I guess to bring it back to the short answer- climate changes over the past 50M+ years are a big reason why the Rose family is so fabulously diverse today, and why it’s evolved so many of the same fascinating anatomical features repeatedly and independently.<br /><br />Sorry, long post AND long comment, but a cool question. Thanks BTW for the researcher perspective on 1st/3rd person and "methods" sections. I have an interesting connection BTW to the cold fusion story which I unfortunately can't share in the blog. Should we ever meet or correspond directly, remind me to share it.Watcherhttps://www.blogger.com/profile/02248341788957416471noreply@blogger.comtag:blogger.com,1999:blog-9199848742267562587.post-89268427212080765942009-07-10T07:23:57.468-06:002009-07-10T07:23:57.468-06:00Wow, that was long!
So, I keep wondering, but don...Wow, that was long!<br /><br />So, I keep wondering, but don't have time to research it, how did plants like the rose ancestor survive the ice ages?<br /><br />As for scientific papers being in the 3rd person, I have some experience with that as a research scientist who actually cares about my writing. I write in the 1st person but some editors insist that I change it - with no logical reasons to support their insistence. I've teased my students when they hand me a 3rd person draft by asking if a secret worker covertly did all the research in the middle of the night and handed it to the student to publish.<br /><br />One other thing about the 'Methods' section is that it needs to be written so that another scientist can replicate the experiment (remember 'cold fusion'?). You'd be amazed by how much detail that standard requires.KBhttps://www.blogger.com/profile/16885661679762446456noreply@blogger.comtag:blogger.com,1999:blog-9199848742267562587.post-37373656691019396412009-07-09T22:21:19.913-06:002009-07-09T22:21:19.913-06:00wasatch wildflower festival. you should become a ...wasatch wildflower festival. you should become a guide next year. www.wasatchwildflowerfestival.org. <br /><br />check out that local guide as well by the cottonwood canyons foundation! localized flower id's, but not as detailed as cyberflora.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9199848742267562587.post-72766250323904599842009-07-07T23:38:17.466-06:002009-07-07T23:38:17.466-06:00Nice pictures - especially that first shot of the ...Nice pictures - especially that first shot of the Crest trail.
