    Girl Scouts playing with animal antlers and pelts during a Nature Museum overnight program

    6:00:  I arrived at the Museum to find 150 other girls with sleeping bags and pillows, waiting to see where we’d be sleeping for the night.

    6:30:  After dropping off our belongings, we all came together in a GIANT circle to meet the staff, sing some songs, and go over the rules for the evening.

    7:00:  I GOT TO MEET A TURTLE. His name is Bob and he’s a Blanding’s turtle. They are an endangered species. I can’t believe I got to pet him!

    7:30:  My troop just got to explore the Museum’s exhibits…and we were the only ones there! It was so cool to have the whole place to ourselves. We built dams in RiverWorks, then spent a long time watching the animals in the Rainforest Adventure exhibit. So cool!

    8:00:  Now I know how to tell the difference between a fox squirrel and a grey squirrel.  I got to touch some real (but no longer living) squirrel specimens and play this fun matching game where I had to find two pictures of squirrels of the same species that matched.

    8:30:  I just ate some popcorn and other snacks in Nature’s Lunchbox.  I loved the chance to hang out with my friends.

    9:00:  Craft time! We made these awesome seed bombs out of clay, dirt, and seeds. I can’t wait to plant it in my backyard.

    9:30:  It’s time to start getting ready for bed. I rolled out my sleeping bag, then I brushed my teeth and changed into my PJs. 

    11:00:  Lights out. I AM SLEEPING AT THE MUSEUM. Ah!

    ::next morning::

    7:00:  Time to wake up! So soon?! 

    8:00:  We had breakfast together and got our badges that prove that we spent the WHOLE NIGHT at the Museum.

    8:30:  Before the Museum’s even open, we got the special chance to explore the Butterfly Haven.  Since we had the place to ourselves, I had a chance to look more closely than usual at everything in there. I didn’t know there were birds in the haven! I love the button quail, running around among the plants. I’m going to come back and visit them again.

    9:00:  I stopped by the gift shop to buy a souvenir from this great trip. I got a stuffed turtle who I’m going to sleep with from now on so I always remember the night I spent at the Peggy Notebaert Nature Museum.

    Girl Scouts examining reptile and amphibian specimens in jars during a Nature Museum overnight program

    Sounds like a great time, right? Well, this is a REAL experience for young girls at the Museum. We are recruiting Girl Scout troops for two upcoming overnights this spring:

    Juniors (4th and 5th graders): April 24-25

    Brownies (2nd and 3rd graders): May 8-9

    5:30pm-9am

    $45/girl, $15/chaperone

    If you know a Girl Scout who might like to participate in this unique program, please have her troop leader visit our Overnight Programs page to register or learn more. Questions can be directed to overnights@naturemuseum.org or 773-755-5100 x5037.

  • The Office That Started It All: A Closer Look at Dr. Edmund Andrews

    Last week we celebrated our 158th birthday, this week we’re recognizing one of the founder who made it all possible. Dr. Edmund Andrews died on this day in 1904. Andrews was born in Vermont and expressed interest in botany and geology from an early age. Although he soon turned his professional focus to medicine, this love remained with him. He studied medicine at the University of Michigan, and became demonstrator of anatomy and professor of comparative anatomy. He became a published author and had his essays featured in medical journals. It was this work that then brought him to settle in Chicago.

    Edmund Andrews in office

    Although he was a practicing surgeon, during his off-hours he returned to his love of nature. It was in his offices that the original members of what was to later become the Chicago Academy of Sciences began to meet. When the Academy was formalized in 1857, Andrews was named Curator of the Academy. By the time Robert Kennicott took over the position in 1863, Andrews had co-founded the Chicago Medical College, and had been appointed Surgeon in Chief of Camp Douglas. Although his medical work kept him occupied professionally, he still remained involved with the Academy. His interest in geology and glacial history led him to publish some of his findings in the Transactions of the Chicago Academy of Sciences, and he served as the President of the Board of Trustees for a number of terms and through some of its toughest years.

    While we recognized and remember Dr. Edmund Andrews for his work with the Academy, he truly made a name for himself as a pioneering surgeon. To learn more about his contributions to the world of medicine, check out the links below.

  • At Least We Have Houseplants

    And the snow lies drifted white
    In the bower of our delight
    Where the beech threw gracious shade
    On the cheek of boy and maid:
    And the bitter blasts make roar
    Through the fleshless sycamore

    ~ Willa Cather

    It’s cold. Like, Siberia cold. I am a person who values his time outdoors, but to heck with this. Blankets, hot beverages, and good books – these shall be the apparatus of my forbearance, until the blessed day arrives when I can stand outside for more than ten minutes without losing feeling in my extremities.

    Winter is hard on a horticulturist (as I have lamented before). But thanks to a the accidental genius of a Victorian-era Englishman named Nathaniel BagshawWard, and the insatiable social ambitions of the ascendant middle class in his milieu, we have houseplants upon which to turn our phytophilic attentions when snowflakes fly.

    With enough space and the proper equipment, virtually any plant can be grown indoors. However, there are a few dozen hardy species that have become archetypal denizens of shopping malls, lobbies, and hotel atriums, as well as residential windowsills. You may not know their names, but you know them: aglaonemas, marantas, spathiphyllums, crotons… 

    Counter to their colloquial reputation, some familiar houseplants have secret talents and unique life stories that are worth investigating…under a Snuggie, with a laptop warming your thighs. So grab another mug of chai, and let’s explore a couple, shall we?

    Ficus tree

    (Courtesy of Kenpei via Wikimedia Commons CC BY-SA 3.0)

    We’ll begin with Ficus benjamina, known as Benjamin’s fig or, more simply, the ficus tree. Despite its deserved reputation as a finicky leaf-dropper, ficus trees frequently adorn large interior spaces. This is due to their tolerance of low light and dry air, and because their fine texture and broad branching structure fit our temperate-zone expectations of what a tree should look like. Native to Southeast Asia, the ficus is a close relative of strangler figs and banyans, and like those plants, will often send down aerial roots from its branches. As with all plants in its genus (including the edible fig, Ficus carica), the Benjamin fig relies on a symbiotic relationship with a particular species of tiny wasp in order to produce seeds.

    Botanically speaking, a fig is not an individual fruit, but rather a receptacle that encloses multiple small fruits (the fleshy bits inside). These fruits started off as hidden flowers, pollinated when the aforementioned wasp entered the fig through a tiny hole in the tip. The wasp lays eggs inside, thus protecting them from predators and providing a food source for the resultant larvae. In return, the wasp performs necessary pollination duties. In a fascinating example of coevolution, nearly all of the 800 or so species of Ficus are pollinated by different, unique species of wasps.

    Monstera deliciosa, aka Mexican breadfruit or Swiss cheese plant

    (Courtesy of Mokkie via Wikimedia Commons CC BY-SA 3.0)

    Surely one of the best scientifically-named plants of all time, Monstera deliciosa, aka Mexican breadfruit or Swiss cheese plant, is indeed a monster of a plant. In its native Central American climes, its stout, vining stems can climb 60 feet or more into the trees. Edible, pineapple-like fruits are sparsely produced beneath its enormous, leathery leaves. 

    Grown indoors, the “delicious monster” typically stays much smaller, and may lack the bizarre fenestration that makes this plant a favorite in humid conservatories. No one really knows the wherefores of the leaves’ “Swiss cheese” stylings, but there are some theories out there.

    As with several other plants in its family, Monstera can actually generate its own heat. At certain blooming stages, its inflorescences (flower clusters) can be as much as 5°C hotter than the surrounding air. This phenomenon, known as thermogenesis, likely aids the dispersal of chemical signals that attract pollinators.

    Dieffenbachia aka dumbcane

    (Courtesy of Louise Wolff/darina via Wikimedia Commons CC BY-SA 3.0)

    Now lets take a look the deceptively euro-sounding dieffenbachia. A relative of the Mostera, the dieffenbachia or dumbcane hails from similar, neo-tropical environs. Its speckled leaves have been bred and selected for many distinct and interesting patterns, which has led, along with its remarkable shade tolerance and overall ease of culture, to the Dieffenbachia’s predominance as a parochial favorite.

    But dumbcane is not without its dark side. In common with its familial brethren, its cells contain tiny, sharp crystals of calcium oxylate that can be extremely irritating to the skin, eyes, mouth, and esophagus. The name dumbcane derives from the tendency of the tongue to swell if the plant is chewed, causing temporary mutism. In the West Indies, exceedingly awful human beings once took advantage of this phenomenon to punish their rebellious slaves.

    Having experienced the harrowing topical effects of the dieffenbachia on more occasions than I like to admit (note to self: GLOVES!), I can attest that potency varies widely among varieties, and tends to be greatest in the stems and roots of large specimens. Fortunately the swelling, numbness, and prickly aches brought on by contact with the plant’s juices rarely last more than a day. And there is a rather unforgettable odor to the cut stems of older plants that serves as a helpful reminder not to rub an eye or bite a fingernail until one has thoroughly washed up.

    This odor comes from compounds closely related to asparagusic acid, which is the same stuff that makes your pee smell funny (giggle) when you eat asparagus. Speaking of which, is there any vegetable that induces thoughts of springtime as reliably as fresh asparagus? I can see them now -- pale stems pushing their way out of the warming soil, ready to drink in the nourishing rays of waxing daylight…I can hear a robin tweeting happily among bursting buds…And the flowers! Daffodils, hyacinths, forsythia!

    Crap. Have you seen the weather forecast?

    We are having a party this week!  The Chicago Academy of Sciences was founded on January 13, 1857 and was the first science museum in Chicago.  Our collections served as the nucleus for the organization of our institution and preserve our natural heritage.  These specimens, artifacts, and associated documents are used as primary source material for environmental studies and historical research.  To celebrate our birthday, we’ve brought out specimens from the museum collections that aren’t typically on display.

    One question we are often asked is, “What is the oldest specimen in our collection?” The oldest specimen in our museum collection, in terms of when it was collected, are two Merlins collected in the Rocky Mountains in 1834 by J.R. Townsend. That's right -- bird specimens that are 182 years old!  One of these is on display.

    Fossils, though, have the award for oldest in terms of when they were created!  This "Tully Monster" fossil is from the Mazon Creek area, right here in Illinois, and is approximately 307 million years old.

    This plant specimen from our botanic collection was collected by Floyd Swink, a prominent botanist who co-authored "Plants of the Chicago Region."  In 2013, Gerould Wilhelm, Swink's coauthor, visited our collections facility to review some of our plant specimens and annotated several, including this one.  These “conversations” left by researchers who utilize our collection adds to the scientific knowledge of those specimens.

    Last month, the Nature Museum hosted 24 Conservation Clubs from all over Chicago for the C3 Club Summit. The Chicago Conservation Corps (C3) clubs are organized by teachers who have gone through C3 Club training here at the museum and are now organizing afterschool programs on environmental conservation issues in their schools with support from C3! 

    At the Club Summit, the clubs got to meet, share, explore, and get pumped up about their club’s Green Vision for the year!

    C3 Student Club Projects

    During the Summit, Clubs shared their Green Vision for the school year:

    Students brainstormed action items for the environmental issue they wanted to undertake this year in their classroom, school, or community. They made posters and recorded a short video that detailed their goal, audience, and steps to complete achieve their Green Vision!

    Clubs also made PLARN (plastic yarn)-for local initiative “New Life for Old Bags”:

    Students repurposed plastic grocery bags by cutting them into strips and looping them together to create PLARN. The PLARN is later crocheted into sleeping mats for the homeless—an initiative started by “New Life for Old Bags”.

    Clubs attended a "Maker Party":

    A number of partner organizations engaged Clubs in production-centered activities focused on sustainability, environmental conservation and youth voice, providing Clubs with inspiration and tools for their own sustainability projects, events, and awareness-raising campaigns in their schools and broader community. The Anti-Cruelty Society’s “PUPcycle & rePURRpose” station had students make upcycled pet toys out of reclaimed cardboard, old t-shirts, and corks. The National Veterans Art Museum showed students how to make animated GIFs. Free Spirit Media & Mikva Challenge provided a model for an awareness-raising social media campaign with their #IDreamAnEarth station.  Other partners who facilitated stations at the Maker Party included The Art Institute of Chicago, Intuit: The Center for Intuitive and Outsider Art, Friends of the Forest Preserves, The Sweet Water Foundation, Scientists For Tomorrow, and CodeCreate.

    During the growing season, I was charged with the fun and interesting task of compiling a list of all plant species growing in the Museum’s “habitat vignettes”. For those unfamiliar with this term, we sometimes use it to refer to areas of the museum grounds where we’ve worked to recreate plant communities that were typical of our area before European settlement. Frequent visitors know these areas well: the Black Oak Savanna, Burr Oak Savanna, Elizabeth Plotnick Tallgrass Prairie, the rooftop garden, (the section visible from the Bird Walk) and our portion of the North Pond edge.

    In creating the plant list, I counted species intentionally planted by us as part of our restoration efforts as well as those that showed up here on their own. The total number of species was 350! Being in list-making mode, I divided these into categories that had more meaning in relation to what we are trying to accomplish with the habitat vignettes. To wit:

    Native Species: 229

                   Planted by us: 159

                   Spontaneous:  56

                   Unknown: 14

    Non-Native: 123

    It’s worth noting that these categories are not cut and dried distinctions. There are differing opinions on whether some species grew here before Columbus. Also, several have strains both from North America and from other continents (which can behave differently ecologically). In these cases, I tended towards the majority opinion of authors who have studied our local flora, weighted by my own opinion. Then there was the matter of how local to get while defining “native.” In this case, I considered a species native if it was known from a county at least bordering Cook.

    A final distinction I wanted to make was whether a species was invasive or not. This entered even blurrier territory as, aside from a few of the worst offenders, there is far from a standard consensus on which species are invasive locally. I used a pragmatic approach, counting any species as “invasive” if we have actively attempted to control or eradicate it. The resulting list included 63 species – 12 of them native, 51 non-native. (Yes, native species can be invasive, too. But that’s a subject for another blog post.)

    Surprises

    In creating any such list, there are bound to be surprises.  For example, I found two native species of Willow Herb in the Black Oak Savanna that are more typically found in wetland habitats. I suspect that seeds or seedlings of these plants arrived in the soil of native plant plugs. (We happened to see Willow Herb growing in abundance at a local nursery). I was also surprised that one of the species we’ve attempted to reintroduce over the years – Marram Grass – seems to have died out completely.  It almost certainly grew here centuries ago when lakefront dunes made up portions of the museum grounds, but now its failure here is a good example of the challenges posed by “restoring” nature in heavily modified environment.

    Historical Perspective

    It is impossible to know the exact species list that would have emerged if I had compiled it a few centuries ago. Historically, this land was sand dune, marsh, oak savanna and probably some prairie. The lakefront was originally much closer to the museum. The topography, hydrology, and soil here have been drastically altered over the last couple centuries, making it difficult to recreate the conditions required by some of the presumed original species. Despite this, both the museum and the North Pond Nature Sanctuary have successfully reintroduced a good number of plants that once would likely have grown here. Have any of these original species survived on the property on their own throughout all of these changes? The answer, sadly, is probably not. However, some native plants were likely in the general area the whole time and would have been able to easily re-colonize the museum grounds. These correlate to the 56-70 species that I’ve listed as spontaneous. Why did some species need to be replanted, while others came back uninvited?    

    Weediness

    You may know that some plant species are extremely sensitive to specific conditions (like Leadplant), while others will grow almost anywhere (Hairy Aster). There is a general spectrum between these two extremes. The species we intentionally replanted tend towards the more conservative, “specialist” side, while those that found their own way here are on the other, “weedier” side. Another way to describe this equation ecologically is that climax species are on one end, and pioneer species are on the other. Pioneer species do well in disturbed areas where bare soil is exposed. This situation always existed in nature but is far more common today, as a result of human land use patterns. As a result, the seeds of these species are practically everywhere. But unlike these weedier species, when more conservative, climax species have been absent for a long while, their seeds are no longer in the soil (or in nearby areas), and thus they generally will not return on their own. 

    Change

    This list might be considered a “snapshot” of what was here in 2014. While I was positively surprised by the ratio of native to non-native species growing here, it should be noted that the species list doesn’t reflect how many individual plants of each species are present, which is what we hope to alter most as the years go by. The quantity of individual, reintroduced native plants will hopefully increase with time. The number of weedy native and non-natives will probably also change, as we extirpate some, and new ones arrive. Now that we have a list, we will be able to compare it to lists of future years, hopefully showing progress as we strive towards recreating lost native habitats.

    Chicago has been a part of the film industry since it began. At the turn of the century, a few of the largest, most popular film studios called Chicago home. Unfortunately, after the West Coast was established as the center of the industry and the studio system was established in the early 1920s, many of these Windy City-based organizations moved west or went out of business. One company that didn’t, however, was the Atlas Educational Film Company. Based out of Oak Park, the company was formed in 1913 with the focus of making educational and industrial films. Many of their films were done in association with the Farm Bureau Federation, but one in particular featured many of Chicago’s museums, including The Chicago Academy of Sciences.

    Sponsored by the Chicago Association of Commerce, the film was called “Background for Tomorrow” and it was produced in 1942. Written by John Gould Curtis and directed by Bertram Bates, the film was sold as a feature-length talkie that focused on telling the story of the exhibits, as well as the behind the scenes activities of several notable Chicago museums. The Chicago Academy of Sciences, The Field Museum, The Oriental Institute of the University of Chicago, the Chicago Historical Society, and The Museum of Science and Industry were the featured institutions, with schools, churches, parent teacher associations and similar organizations as the target audience.

    Filming began at the Academy on May 1, 1942. As detailed in the Chicago Naturalist Volume 5, Number 1, the Atlas team shot exteriors of the building, a visit to the Director’s office, and several scenes in the main exhibit hall. The behind the scenes footage included a look into how habitat groups were constructed, in addition to the process of preparing celluloid leaves and installing them in an exhibit.

    By the end of the year, the Atlas team had completed filming and production, and the film was released. The Educational Screen reviewed it for its January 1943 issue, and praised it for its ability to present museums as “live educational centers teeming with activity and wielding a powerful influence on the minds and thoughts of millions that come within visual range of their intellectual treasures.” It also highlighted the film’s efforts to “show how events and developments from the remotest past to the present day furnish the experiential basis for still richer future for the human race. Those who still incline to think of museums as merely mortuaries for dead facts of the past should see this picture. It is a revelation of what museums really are and what they can mean to children and adults alike.”
