Meet our new millipedes!

Post written by Alexa Leinaweaver, Live Animal Husbandry Coordinator.

We have a new exhibit up in the Animal Encounters zone: Millipedes!

The name “millipede” comes from Latin and means “thousand feet”. Millipedes have two pairs of legs for each body segment and usually more than 20 segments – which is a lot of legs! – but no millipede has actually been found that has 1,000 feet.

Millipedes eat vegetables, fruit, decomposing plants, and will even eat poop from other animals. They are the cleaning crew for the animal world!

These arthropods will curl up into a spiral or coil when they feel threatened. They can also burrow underground to find protection from predators, as well as food and cool temperatures.

There are a few different kinds you can find in our tank:

Florida Ivory Millipede (Chicobolus spinigerus)

The Florida Ivory millipede is native to the American Southeast (Florida, Georgia, Alabama). They are smaller and black-and-white striped.

American Desert Millipede (Orthoporus ornatus)

The American Desert Millipede is native to the deserts in the American Southwest. This species comes in several colors, depending on where they live and what colors keep them camouflaged and safe. The dark red-brown millipedes in the tank are also called Sonoran Millipedes, as that color tends to be found in Arizona, in the Sonoran Desert. The brown and gold millipedes are also known as Texas Gold Millipedes, as they are found in – you guessed it – Texas.

Come see FCMoD’s millipedes during our open hours and stop by for our monthly series, Meet the Animals!

Sugar Beet Science and Microbiology

Post written by Jenny Hannifin, Archive Research Assistant.

Did you know that scientific research using the humble sugar beet led to the birth of microbiology?

In the 1800s, agriculture and manufacturing industries struggled to meet the demands of a growing and changing population. Science was applied rigorously to solve domestic challenges, and the “industrialization of agriculture was reflected in the growth of the sugar beet, fermentation and other food industries.” (Needham, p. 189)  Scientists in the mid-1850s wanted to understand the chemical nature of living matter, not only for the betterment of agriculture, but for the sake of pure science.

Louis Pasteur (1822 –1895), famous for his vaccines and processes of sterilization, began his career by studying the crystalline structure of organic substances. He believed that asymmetrical structure, which produced optical activity (the polarization of light), was related to life itself, and that processes like fermentation worked because the substances involved were alive (what we now call microbes or microorganisms). Pasteur taught his students the principles of bleaching, sugar refining, and fermentation, including the processes used in the manufacture of beetroot alcohol.

Sugarbeets were a big industry in France, and one of the Lille distilleries asked Pasteur to help them solve a problem they were having with spoiled product. Pasteur analyzed the fermentation processes that he observed at M. Bigo’s sugarbeetroot distillery (circa 1856), and tied those observations to his research on the asymmetry of living substances.

What began as a search for the cause of spoiled beet alcohol led to a full-on investigation of fermentation. If the products of fermentation were alive, as Pasteur thought, then fermentation was a living process, not one of decay, as was believed by many scientists at the time.

But if that were true, where did that life come from? Could it spontaneously generate, as some believed (Pasteur thought not)? Fermentation was at the root of important scientific debates at the time, and investigating questions like these heralded the beginning of microbiology (the study of microscopic organisms).

Pasteur eventually proved that microbes in the air we breathe kick-start many processes (like fermentation) that are inherent in organic matter. Pasteur also determined many important principles about living microbes; for example, that microbes infecting animals caused disease, the so-called “germ theory” of disease.

Leave it to Beaver: Conservation of our natural and cultural heritage

Post written by Linda Moore, Curator of Collections

(A personal disclaimer: I grew up in Oregon–the Beaver State; in Corvallis, which is the home of Oregon State University and, of course, the mighty OSU Beavers. Our family drove around with twin stickers on our back-bumper declaiming “I’m a Beaver Believer” and “I’ve Got Beaver Fever.” I come by my love for these buck-toothed engineers honestly, and my “beaver fever” is unabashed.)

My experience with historical research has taught me that it can be almost impossible to pick up and follow a single topic: inevitably one thing is knotted on to another, tangled up with a dozen more, and sometimes tied on to its own tail. This has been the way it’s gone with my research on the beaver felt top hat of my last post. My research on that object made me curious to see what other artifacts of beaver history are preserved in the Fort Collins Museum of Discovery’s collections. Turns out it is an impressive inventory:

3 beaver felt top hats in addition to the one attributed to President Lincoln

1 elegant felt lady’s riding hat

2 wide-brimmed beaver felt Stetsons

1 pair of beaver fur mitts

1 bearskin coat trimmed at the collar and cuffs with beaver fur

1 sweet beaver fur cape and muff set, made from beavers trapped on George Campton’s ranch in Livermore about 1910 for his sister

1 old beaver trap, pulled out of the Cache La Poudre River and donated to the Museum in the 1960s

1 pelt from a beaver trapped by the donor himself in Colorado and donated in 1979

2 stuffed and mounted beavers (the largest and fattest dang beavers I’ve ever seen)

a set of beaver skulls

and, finally, various pairs of bright orange upper front beaver teeth

The presence of these beaver-related objects in the Museum’s collections reflects a steady involvement of the species in our region’s history, despite an economically driven “beaver fever” that severely depleted their numbers before Colorado had even become a state. The earliest historical trapping records of the Colorado Rocky Mountain region show sixty to eighty beaver present per mile of stream. By the turn of the 20th century the species’ population nationwide was as low as 100,000 individuals, very few of whom were here in the West.

Two sources I’ve come across recently not only decry the West’s loss of beaver populations, but advocate their protection and reintroduction as a means of conserving our region’s natural and cultural riches. Both recognize that in shaping the region’s waterways to their own purposes, beavers once played, and can play again, a vital role in maintaining the environments in which the region’s unique human history has unfolded. The first of these is Beaver World, a charming book by Enos Mills, a signed copy of which is in the Fort Collins Museum of Discovery’s Local History Archive. Mills was a passionate advocate for the natural world, and an astute direct observer of wild animals interacting with the environment. Beaver World was published in 1913, and in it Mills not only gushes about the beaver’s emblematic industriousness, “He works not only tooth and nail, but tooth and tail,” but more insightfully recognizes the role the species plays in maintaining both a healthy ecosystem, and a landscape humans find welcoming and pleasing:

Beaver works are of economical and educational value besides adding a charm to the wilds. The beaver is a persistent practicer of conservation and should not perish from the hills and mountains of our land. Altogether, the beaver has so many interesting ways, is so useful, skillful, practical, and picturesque that his life and his deeds deserve a larger place in literature and in our hearts.

The beaver’s role in maintaining healthy, functional Western ecosystems is the central focus in the much more contemporary article “Voyage of the Dammed,” carried in The High Country News. Writing at a time when water conservation is a high-profile problem and many of its proposed solutions carry high price tags, author Kevin Taylor outlines the position of environmentalists and other concerned citizens who advocate, at least in part, leaving it to the beavers:

The humble, hardworking rodent, through its dams and ponds, can extend the release of water late into summer, saturating the ground and healing watersheds. It has the power to re-create the primordial, wetter West that existed for millennia.

The article extends the beaver’s vital restorative role to cultural values as well. Taylor quotes a Coeur d’Alene tribal elder, 86-year-old Felix Aripa, who sees within the native ecosystems restored by beaver activity the roots of cultural restoration: in the returning native plants, fish, and animal species are embodied the cultural riches of language and long-held cultural knowledge.

These two sources have whetted my appetite for learning more about this species, and for doing what I can to promote its ongoing presence in our region. I understand that in caring for the beaver artifacts which lie within the Fort Collins Museum of Discovery’s collection — clothing, tools, and scientific specimens — we preserve the history of a species which plays a central role in the Native American traditions of this area, as well as in the story of the region’s surge in population and development in the 19th century. As I read the strong praise Enos Mills gives this species and the excited plans of those advocating its restoration, I’m thrilled with the possibility that within today’s beaver population is preserved a solution to our region’s compelling need to conserve both the health of the environment and the wealth of our cultural and historical heritage. “I’m a Beaver Believer” indeed.
