Kaitlin Karl, an Ecology, Evolution, & Behavior PhD student in the Cooperative Conservation Genetics Lab (CCGL) at the Illinois Natural History Survey (INHS), brings a deep-rooted passion for preserving biodiversity. With an academic background from Southern Illinois University and current research under the guidance of Mark Davis, Kaitlin is delving into phylogenetics, population genomics, and disease ecology, particularly within herpetofauna. From uncovering novel parasite species in Peruvian frogs to studying a vulnerable Timber rattlesnake population in New York, her work is contributing to species conservation. We sat down with Kaitlin for this edition of “People of PRI” to learn more about her journey, her favorite tools, and advice for aspiring conservationists.
Q&A with Kaitlin Karl
Q: Can you tell us a little bit about yourself and your role at Prairie Research Institute?
A: I joined the Prairie Research Institute and the (CCGL) as a PhD student under Mark Davis in June 2024. Before starting at the University of Illinois Urbana-Champaign, I completed my B.S. in Zoology at Southern Illinois University (SIU) and graduated in May 2024. My research focuses on conservation biology, particularly phylogenetics, population genomics, and parasite diversity related to herpetofauna. While at SIU, I studied the parasites of several Peruvian frog species, identifying a handful of novel parasite species. Since joining PRI, I’ve been analyzing the evolutionary relationships of a newly identified gartersnake species from Veracruz, Mexico. Moving forward, I’m excited to begin my dissertation research at U of I, which will explore the population genetics and disease ecology of a vulnerable Timber rattlesnake population in Northeastern New York.
Q: What drew you to your area of work or study?
A: I’ve been fascinated by wildlife for as long as I can remember, especially reptiles and amphibians. Some of my earliest memories are of dipnetting tadpoles and searching for snakes in the natural areas around my hometown in central Illinois. My interest in conservation genetics and species description stems from a deep desire to preserve and document biodiversity.
Q: What tools are indispensable to your work?
A: A computer is crucial because it allows me to access various bioinformatics programs, enabling me to construct phylogenetic trees and perform DNA sequence analyses. A compound microscope is also indispensable for examining the tiny morphological details of different species, from gartersnake scales to nematode feeding structures. Lastly, my field journal is a treasured tool, filled with drawings and notes of species I encounter, which often serve as references for scientific illustrations in manuscripts.
Q: What questions do you get asked most frequently about your career?
A: The most common question I get is, "Why study reptiles and amphibians?" While they might not appeal to everyone, reptiles and amphibians, along with their parasites, are among the most diverse and fascinating taxa on Earth. However, they’re also some of the most understudied. These species play critical roles in ecosystems, but many are declining at an alarming rate, making conservation efforts essential.
Q: What advice would you give to those just starting out in your field?
A: Stay curious and don’t hesitate to reach out to others in your field about research opportunities. Being proactive in seeking out experiences can lead to unexpected collaborations and projects you may never have considered.
Q: What do you do in your free time?
A: I enjoy painting, field-herping, and reading. I also love scrapbooking with my mom and sisters, and going on hiking and camping trips.
