Solving Mysteries on the Beach

One of my favorite things about my work is learning new things about environments I'm familiar with - going outside, exploring, and asking questions!  My family and I went walking along Sanibel Island during low tide and came upon a mystery.  We found these critters just floating in the shallow waters and had no idea what they were.  They were squishy and had "hairy" tentacles all over its back, but its belly was smooth.  We didn't know what it was, so we started to investigate and ask questions, biomimicry style.
Mystery Critter
We noticed it didn't have a shell like the other tidal organisms we found in the same area.  Why does he have a soft body when all of the other creatures here have a shell?  Especially in tidal areas, where this makes him more vulnerable to the ever present sea gulls.  What are the tentacles for?  Protection?  Camouflage?  Why was its belly so smooth and almost a thin membrane that concealed its insides?  And maybe the most interesting question - why was it here and why were they floating, seemingly lifeless?

Shelling (and Learning) with Kids

I have channeled my inner "snow bird" and flown south to Florida for a family vacation.  One of the first things we did - stopped at the beach!  Even a couple of sick kids can't keep us from the beach on New Years Eve Day.  While sitting there and digging in the sand, we found so many different shells that all had holes in them.  I channeled my inner Dayna (Baumeister, my illustrious biomimicry instructor) and explained to my daughter that the holes in the shells were not put there in order to make necklace creation easier (as she thought), but there because another type of mollusk (shelled invertebrate) drilled down into the shell with its tongue (!) and sucked out the poor clam through the hole and ate it!  The predator in this area - most likely a whelk.

"Sea snails use a radula, their ribbon-shaped tongue, to drill a hole in the shell of the clam. While drilling, the snails soften the shells by secreting carbonic acid and inserting the siphon. The clam is then digested inside its shell as the snail gulps down the remains of what Gulf Islands National Seashore park rangers call a 'clam milkshake.'" (Credit 6)

Thinking about Migration

I have emulated the fair weather birds and temporarily migrated to warmer climates – Florida!  My family has temporarily become a “snow bird” and escaped the Chicago winter in favor of the beach and the pool, if only for a week.  And it got me thinking about migration.

The energy it takes to move a body hundreds if not thousands of miles to find food and stay warm is immense.  Migratory birds have physical as well as behavioral adaptations that allow them to complete this momentous feat twice every year.  Some birds lose over 50% of their body weight burning fat to make an uninterrupted trip.  Other species fly the same route seasonally, and certain plants even time their flowering to coincide with the journeying pollinators.  Birds that migrate during the day take advantage of thermal currents over land.  Those that migrate at night avoid predators and overheating.

Human bodies have adapted to almost every climate on this planet through fat and our brain’s ability to manufacture clothing and artificial heating, but those with the means still find a way to migrate to warmer climates, if only for a short winter break.  While our bodies are fed and warmed through the long winters, it seems it heals the spirit to visit the sun.

Teaching Biomimicry to Young Kids

I have young kids preschool and kindergarten age, and one of my favorite things to do is to show them what I do by going outside.  On a recent day in late fall, we went into our backyard and went on a critter search.  Squirrels are abundant in my backyard because of the leftover food in the garden as well as the large maple tree which dominates our small lot.  So we set about investigating and learning about the squirrels.
Squirrels and their Amazing Tails
Children learn by doing, so at first we acted like squirrels.  We brought our hands up into claws and pretended to eat an acorn.  We hopped around on two feet simultaneously.  We wiggled our rear ends.  We talked about what they ate – acorns, ideally.  In our yard, birdseed, strawberries, pumpkins, the bulbs I had planted for spring (grrr) and really anything left in the garden that we didn’t harvest.  Then we talked about what eats them – dogs and coyotes came to mind, although our dog is much too old to do more than bark at them.  Then we pretended to be a squirrel and a coyote, a glorified game of tag, which they loved!  After all that exertion and thinking, we went back inside to do a little research and drawing.  I researched, my oldest drew a squirrel from a picture, and my youngest drank hot cocoa (Chicago is cold in November!).

Changes in the Prairie Over Time

I've been visiting our local prairie preserve for a couple of years now and the summer of 2012 was different. It was a summer of drought, and when I visited this summer, the changes were noticeable.

In our Tallgrass Prairie biome, the grasses should have been at least up to my chest and the majority of them were at my knees.  Certain areas that weren't burned have tall stands from last year next to the short ones of this year.  There are no credit cards in nature, so if the heat and drought were too much for one season, the grasses go dormant and wait for the following season.  Unlike our economic system, there is no unlimited growth in nature.

Taking a 100 Year Nap

Sometimes it is fun to go on creative thought experiments, like what would happen to your home if you took a nap for 100 years and woke to see what it would look like without adding the human energy and capital necessary to maintain it. One day in late summer, I did just that as I sat on the driveway in my front yard watching my kids ride their bikes up and down the street.

I live in a wood frame, two-story single-family home in a downtown area of a suburb outside of Chicago. The siding is cedar and the base in the front is clad with limestone. To the east our home is a large walnut tree that hangs over our house unless it is trimmed back. At the north-west corner is another large elm tree. Both are approximately 100 years old. So, if I were to sleep for 100 years old - what would my home look like? What parts would nature reclaim and what parts would remain recognizable?

Prior to settlement, my home was a part of a larger swath of oak woodland adjacent to a tallgrass prairie, so I can imagine that through drought cycles inherent in our climate, this type of vegetation will gradually overcome some of the introduced landscaping plants so prevalent in our neighborhood.

Deeply Listening to Nature

For this iSite, I was to work on improving my listening ability - but not in listening to other humans (though that could always use some work).  I was to listen to the creatures around me on a particular place in time, defer judgement, set aside distractions, and be present.  In this instance, in the woods while camping in British Columbia.
Wildlife Tree
I started out thinking about my stomach moving and the scratch of my pen as I wrote in my journal.  I heard waves crashing at an adjacent shore and birds honking and tweeting all around me.  I began to stare at a "wildlife spire," otherwise known as the stump of a 4' diameter Douglas Fir which had become a colony of life for moss, lichen, insects, micorbes, etc.  I thought about how the destruction of one life led to life for countless others smaller than the original.  I thought of Shiva, the Hindu God of destruction that is also the bringer of life and saw the beauty in its decay.  Life is opportunistic.  It grabs resources when it can.  And Life finds a way.
