An Afternoon with Organisms, Evolution, & Ecology

May 25, 2023

It鈥檚 a sunny Wednesday afternoon in mid-April, and my car bounces along a dirt road. I鈥檓 on my way to the Conard Environmental Research Area (CERA), 乐播传媒入口鈥檚 ecological field station, to join Professor of Biology Liz Queathem and the students in her section of Organisms, Evolution, and Ecology. Today, they鈥檙e surveying the oak and hickory forest on the property to identify the spring ephemeral wildflowers in bloom. 乐播传媒入口ians have been coming to this forest to document spring ephemerals for over 100 years. For many, it has been and continues to be a favorite field exercise:

1:15 p.m. En route to CERA I see a red-tailed hawk swoop low over the road. The 252 students aren鈥檛 planning to birdwatch (not today, at least), but this is a nice nature encounter to kick off the afternoon.

1:21 I pull onto CERA鈥檚 winding gravel road and arrive at the Environmental Education Center (EEC). The prairie that surrounds me is just beginning to green up after a season of underground dormancy.

1:23 Two sprinter vans arrive at the field station and 23 乐播传媒入口ians in long pants and closed-toed shoes tumble out. I notice that I鈥檓 the only one wearing shorts 鈥 embarrassing.

1:25 In the EEC, students pore over maps of the property. They鈥檝e been assigned specific plots in the forest to survey with their lab partners today.

1:29 鈥淚t鈥檚 a beautiful day to be out here,鈥 Queathem announces to the room. 鈥淭his time, we probably won鈥檛 have any tornadoes.鈥 It seems like the bar for 鈥済ood lab weather鈥 might be quite low.

1:30 Mindy Sieck, biology technical assistant, runs the class through the protocol for the day. 鈥淪oil cores taken from these woods show that it鈥檚 been forested for about 1000 years,鈥 she tells us. In a region as transformed by agriculture as Iowa, that鈥檚 a remarkably long-standing forest.

A line of people walk along a trail through the woods, away from the camera. They carry buckets, backpacks, and notebooks.

1:32 鈥117 years ago,鈥 Sieck continues 鈥Henry Conard started bringing students here to look at spring ephemerals. He and his students would take the train to Kellogg and then walk the rest of the way 鈥 more than three miles.鈥 I鈥檒l never complain about a commute again.

1:36 It鈥檚 time to head out to the forest. Students clamor to grab paint buckets filled with tape measurers, neon flags, and segments of PVC pipe.

1:37 鈥淲e want to wrap up by 3:05 so you have time to wash up for poison ivy,鈥 Queathem announces, and I now understand why everyone wore pants.

1:40 A quarter mile or so of gravel road takes us to the edge of the forest. At the trailhead, students break into clusters around the botany experts who鈥檝e joined us today.

1:42 鈥淭his is the gooseberry,鈥 Stephanie Roush, 乐播传媒入口鈥檚 greenhouse manager, points. 鈥淎nd ooh! Here鈥檚 a violet!鈥 She shows us a small yellow flower.

1:43 鈥淥h? But it鈥檚 yellow 鈥.鈥 Eva Cuevas 鈥25 says what we鈥檙e all thinking.

1:44 Roush explains that not all violets (Viola odorata) are violet in color and that they can be purple or yellow. Counterintuitive but also kind of cool.

White wildflowers shaped like an upside down pair of pants bloom on the forest floor.
Dutchman鈥檚 breeches (Dicentra cucullaria), so named for their resemblance to pantaloons.

1:45 鈥淭his flower that looks like an upside-down pair of pantaloons, those are Dutchman鈥檚 breeches,鈥 Queathem points. Dutchman鈥檚 breeches (Dicentra cucullaria). Now that name is apt.

1:47 鈥淲ait, did you say these were Dutchman鈥檚 briefcase?鈥

1:49 Sieck kneels by a flower with spotted leaves 鈥 a trout lily. The spotted leaves are named for their resemblance to the speckling on the side of a trout, she explains.

1:52 After 10 minutes of careful observation of the forest floor, we鈥檝e reached the post marking the first experimental plot.

1:53 Students head to their assigned plots, drop their buckets, and get to work. With two tape measures (staked into the ground via screwdriver) and a collection of flags, they begin to set up a grid of randomized points.

1:56 鈥20! 21! 4! And 11!鈥 Oscar Angell 鈥25 shouts to his lab mate. She鈥檚 barely visible as she trails a tape measure over a ridge.

2:00 The forest looks like a crime scene right now, with students stalking through the brush and planting flags as though marking evidence.

2:05 Random coordinates marked, student assemble their PVC quadrants and begin the daunting task of identifying the spring ephemerals in the one-meter square at each point.

2:09 Kneeling on the forest floor, Henry Liu 鈥25 jots notes while his groupmates inventory the blooms in their quadrant. Queathem stops by to offer them some ID help: 鈥淩ecognize this one? 鈥極h! Hans! I鈥檝e gone and put my pants in the dike!鈥 鈥 Dutchman鈥檚 breeches!鈥

2:22 The plant identifiers are starting to find their groove. Mostly. Sometimes their guidebooks don鈥檛 help much. 鈥淚s that one just 鈥 grass?鈥 a student asks Roush. It鈥檚 not.

2:30 鈥淭his one that鈥檚 not cutleaf toothwort, I鈥檓 pretty sure it鈥檚 black snakeroot,鈥 Cuevas says. 鈥淪layyyyy,鈥 her partner exhales in celebration.

2:40 A student is now barefoot. 鈥淚鈥檓 hot,鈥 he offers by way of explanation. Alrighty.

2:41 I find a massive patch of violets that are indeed violet in color. Some order is restored to my world.

Four people kneel around a square quadrant. They are examining the blossoms within the square and comparing them to a reference sheet.

2:43 I am startled out of my wildflower reverie by a scream of, 鈥淎hhh! Tick! Tick! Tick!!!鈥 鈥淲hat did it look like?鈥 Queathem is on the case.

2:44 鈥淚t was red! Oh. You know what 鈥? It might have been a beetle. My bad.鈥 False alarm. Alarming, nonetheless.

2:47 Angell discovers a cluster of hard shelf mushrooms on the trunk of an oak tree. An impromptu fungi drum session breaks out.

2:50 Students have reached a steady and rapid rate of shoot identification: 鈥淲e鈥檝e got dogtooth violet, spring beauty, some donkey ear, liverwort 鈥 that鈥檚 it. Boom. Next!鈥

2:53 鈥淢ayapple looks like a cocktail umbrella,鈥 a student points out. And, you know what? He鈥檚 right.

3:04 We鈥檝e been out in the forest for over an hour. As students finish up in their plots, they deconstruct their PVC quadrants and collect the blue and orange flags. The vista looks a bit less crime scene-esque.

3:10 On the walk out of the woods and back to the EEC, Roush reminds students of a wildflower walk to be hosted at CERA the following weekend. 鈥淚f you go, you鈥檙e going to already know a bunch of the species.鈥

鈥淵eah, and we can intimidate everyone with our knowledge,鈥 a student adds. Intimidation is, of course, the primary reason anyone studies wildflowers.
