As a child, Kate Ihle was a “towny,” a kid who lived in Thief River Falls, a small agricultural community in Minnesota. She had friends on the swim team, was a lifeguard during the summer, and hiked in the woods and swamps nearby. Did she know that being a scientist was in her future? Not exactly.
“I was always collecting crayfish, frogs, turtles….but, let them go afterward,” Ihle confessed. “I basically just really liked being outside and exploring.”
It wasn’t until she watched a TV special about oceanographer Jacques Cousteau that her interest in science and fascination with animals took hold.
“By the time I went to an undergraduate college, I was set on studying biology,” Ihle said. “I chose Carleton College, a small liberal arts college, joined sports teams in track, cross country and ultimate Frisbee, and signed up for a bunch of different classes.”
There are so many different types of subjects to study in biology in school – microbes, plants, animals, fish, insects, parasites, birds – that when Kate started her research experience, she decided to start with a summer study in genetics.
“I studied yeast genetics in a program called Research Experience for Undergraduates that is funded by the National Science Foundation. And while it taught me that I loved research, I also discovered that I didn't really want to do genetics,” said Ihle.
When she graduated from college, the feeling of “not quite being sure” what type of biology excited her most stayed with her. So, Ihle decided to go to work in a research lab as a research technician to find out what kind of scientific research was right for her. First, she did studies in neuroscience. Then, she studied ion channels in cell membranes. “I was super lucky. All my bosses mentored me, encouraged me to take classes, and helped me to try to find jobs or volunteer positions so that I could find exactly what I really wanted to do.”
Surprisingly, it was when she worked in a honey bee lab that she found her passion. “I loved it. I got to mix lab work with the out-of-doors!”
Now with a doctoral degree in biology, Ihle not only studies honey bees and the way that bees in general organize their social groups, she has gone to focus on a particular bee - an orchid bee - found in the cloud forests of Panama.
Why study orchid bees? “Female orchid bees don’t typically live in organized hives like honey bees do. Most of them nest alone or in very small groups. I wanted to know why they developed such a flexible lifestyle – what made their social relationships so different from those of honey bees.”
This kind of curiosity is what makes Ihle a great scientist; one who will travel all the way to the tropics to find answers to her questions.
Cloud forests are unusual. Tropical conditions, combined with fog, clouds, rain and wind in heavily forested mountains create a very wet, cool environment. Luckily, the orchid bees that she studies like to nest by the highways, rather than deep in the dense damp forest! “I don’t know if they just like being near the forest’s edges, or along the exposed sides of streams or rivers, but nesting by the highway seems to be their favorite,” said Ihle. “Because of that, I've found 100 nests this year and gotten to also know the truck drivers of Panama really well!”
Ihle has also studied a sweat bee on Barro Colorado Island, an island in the Panama Canal. This bee has some similar social structures to orchid bees. “What’s interests me is finding out why some females live alone and why others like to be together?”
Though on her own and far from family and friends, Ihle describes her work as “pretty close to my dream job.” She says, “I have a Smithsonian Fellowship for the next year and until that ends, I’ll be up in the cloud forests, picking up lots of animals, learning about them and putting them back – just like I loved to do as a kid!”
