Back at the museum, sculptors re-created each animal's body—down to musculature and tendons—in clay around a posed skeleton. "The anatomy on these specimens is absolutely incredible," notes George Dante, founder of the company Wildlife Preservations who led the taxidermy restoration efforts for the project. The original taxidermists tanned skins on models shaped to the sculpted bodies, then returned the preserved skins to each animal, ensuring a precise fit.
In the pre-plastic era of the 1930s museum artists used wax, paper, lacquer, wood, plaster, burlap and fabric to create convincing leaves, stems, rocks and other elements. With every detail composed to re-create the specific site, "you are transported to this spot," Dante notes. "Each one is a specific time and place. They serve an important purpose in that respect. So you can actually find this exact location and see how it's changed over time—how the vegetation has changed, how the landscape has changed."
Some of the best-known background painters, including James Perry Wilson and George and Belmore Browne, carefully captured the scene using an exacting grid system to make these curved-wall backgrounds appear infinite.
The trouble with time
The first 10, masterful dioramas—including the American bison and pronghorn antelope, the Alaska brown bear, the moose and the wapiti—were sealed behind glass for the 1942 opening of the exhibit. An additional 19 were added in 1954 and small mammal dioramas were completed in 1963. And rarely had any of the dioramas been touched since; one was opened to replace a fallen branch and another to restore faded snow.
They had not even been opened to rectify small inaccuracies. Most dioramas were meant to represent the snapshot in time when the animals were collected. But in the American bison and pronghorn antelope diorama, the scene was intended to depict the herd structures present in the mid-19th century, when bison still roamed free in great numbers. One visiting botanist, however, had noticed that the grasses in the foreground were invasive, nonnative species that had arrived by the 1930s but would not have been growing on the Great Plains in the 1850s.
In addition to new scientific understanding, the material integrity of the animals themselves began to shift, adversely affecting their accuracy. Over the years, the dioramas acquired a well-worn dusty look, as they faded far from their original coloration. The unfiltered fixtures that illuminated these displays had rarely been upgraded in the past 70 years, which meant the dioramas were being bombarded with UV-wavelengths that sapped the colors out of the animals' natural coats and some of the scene elements, such as snow—and as Elkin points out, "nobody likes yellow snow."
The new for the old
With the restoration project, museum experts at last had an opportunity to return the scenes to good scientific standing. Their main priority was restoring faded animal furs to their original colors. One of the major challenges was "gaining access to the taxidermy without damaging the dioramas," Elkin says. "While we were trying to remedy one thing, we didn't want to damage another." Some of the smaller animals could be carefully removed but many, such as the 500-pound bison, were too large to risk transporting. For these animals the museum built temporary wooden scaffolding into the dioramas to save fragile grasses and plants from being trampled, allowing conservators and taxidermists more freedom to work inside. (This intimacy was not always easygoing, however; "the wolves were a little scary when the glass comes down," says Elizabeth Nunan, who worked with Elkin on the conservation aspects.)

"This enables researchers to track changes in coloring and habitat due to, for example, rapidly advancing climate change." - Don't you just love how each and every supposedly scientific article, no matter what the purported and/or stated theme of it supposedly is these days, just never fails to get its dig in about "manmade global warming" aka "[global] "climate change?" And so now it's again evolved further (for the dramatic purposes of this article) into "rapidly advancing" "climate change!" I swear! An article could be about string theory or polar auroras, and I honestly wouldn't be in the least bit surprised to hear global warming (or any variant) be given a "shout out," even in an article such as those! Give it a rest for God's sake! This is the exact reason I finally CANCELLED my Scientific American magazine. If you want to discuss it (climate change) rationally, (you remember rationally, don't you?) and in a focused and pointed manner within a story of relevance,, then fine, but to have it repeatedly infiltrate, in such a sub-rosa fashion, each and every article published, as a superfluous, incongruous component to the stated purpose of the story,, well then sorry, I can't, don't and won't buy it, and I am no longer going to be buying from you either...
Upon reading "rapidly advancing climate change" I jumped to comment, only to discover that you did it for me already!
Reply | Report Abuse | Link to thisScientific American must have an employee responsible for ensuring that some variation of the phrases "global warming" or "climate change" occur in every other article.
Well, Nagnostic and Lewtheprof, have you guys ever had a subscription with Objective reality and by the way, it is free!
Reply | Report Abuse | Link to thisFirst of all, I was a long time PAYING customer of the hard copy of Scientific American. I did finally )in disgust) switch to Science News, and honestly, it is a lot better (in this respect we are discussing),, not perfect but better. Finally though, just why would you think that opinion, editorializing and proselytizing should be [allowed to be] a part of the articles within any such a "hard news" or supposedly fact based science journal. If you knew anything at all about the history of this magazine, you'd know it is not (never been) the norm for it, historically speaking. This is clearly a path into sensationalism for them, at best,, into politically driven, advocacy/propaganda journalism at worst. They've sullied themselves with this, and my guess is that in some way (probably credibility) it'll ultimately hurt them. It's clear that they are unconcerned with that possibility right now, or are but another willing sacrificial lamb for the cause of pseudo-scientific advocacy for that which is politically expedient in our time.

BTW, free or not, it's still propaganda and propagandizing. You and others like you, are enabling them and those like them by rationalizing and so by default, defending them. Is that really the right thing to do, whatever the topic? Just remember, "Opinion Journalism" is an oxymoron!
Hmmm...I did not read them to say 'manmade' global warming. If you do not believe in global warming, whether manmade or otherwise, it seems to me you are the one who is not being objective, it is a fact, not an opinion. The fact of the matter is, the changes caused by global warming are relevant to the discussion, and therefore appropriate to the article. You might be a denier of global warming, just as you might be a denier of earthlings having walked on the moon, or the earth being round...the fact you want to continue to believe something that has no scientific objectivity, does not make you objective, just irrational. There is a difference between healthy skepticism, which is in my view a virtue, and wearing blinders to any fact that does not support 'your opinion'. As they say, you are entitled to your own opinion, but you are not entitled to your own 'facts'.
Reply | Report Abuse | Link to thisIt's rather surprising to see an article in a scientific magazine refer to "pronghorn antelope" in a natural history article. I had thought that pronghorns were not antelopes, but a completely independent species. Was I wrong?
Reply | Report Abuse | Link to thisPronghorns are members of the family Antilocapridae, while "antelopes" are members of several different subfamilies of the family Bovidae. The term "antelope" is used to indicate a tropical or subtropical bovid, usually from Africa, that has a particular general size, temperament, shape, build, or head/horn shape. For example, the eland, an oxlike bovid, is considered an antelope based on habitat, head shape, temperament, and build. Such distinctions are often rather arbitrary.
Reply | Report Abuse | Link to thisIf you are going to give before and after shots, as with the Bison, please try to use comparable lighting and exposure. I would also be curious (a) what happened the Bison's "before" bird and (b) why was the "after" bison given a vigorous hair blow out (looks like 60s dos)? I would have expected the bison was originally given somewhat matted head hair as more likely in nature (rain, sweat, lack of combing, etc.).
