    • Ph.D., Yale University
    • USDA Forest Service Scientist
    • As a molecular ecologist, I use genetic data to study how species interact, including how introduced species move around the world.
  • Laurel Haavik, Forest Entomologist

    • Ph.D., University of Arkansas
    • USDA Forest Service Scientist
    • A forest entomologist studies the habits of insects that live in forests.
  • Karen Dillman, Lichenologist

    Forests & Plants

    • M.S., Arizona State University
    • USDA Forest Service Scientist
    • A lichenologist is someone who studies lichens in their natural habitat. Lichens are made up of more than one organism, but the main partners are fungi and algae. The fungal partner is the body of the lichen we can see easily in nature, while the algal partner is hidden inside the fungal layers.
  • Doug Booher, Ecologist, Entomologist, and Evolutionary Biologist

    Insects

    • Ph.D., University of California, Los Angeles
    • USDA Forest Service scientist
    • As an ecologist and an entomologist, I study the functional importance native ants provide to ecosystems and the impacts invasive species have on native ant communities. As a taxonomist, I describe new ant species.
  • Emilee Poole, Entomologist

    Insects

    • Ph.D., University of Georgia
    • USDA Forest Service scientist
    • As an entomologist, I’m interested in the interactions between plants and insects. I study forest health by looking at native and invasive pests, their impact on our forests, and potential management strategies.
  • Monika Derrien, Social Scientist

    Forests & Plants
    PDF preview of the front of Monika Derrien's collector card showing Dr. Derrien standing outside in a park.
    • Ph.D., University of Vermont
    • USDA Forest Service Scientist
    • A social scientist studies interactions among individuals, groups, and societies.
  • Mariko Yamasaki, Research Wildlife Biologist

    Wildlife
    Front cover of Mariko Yamasaki Collector card
    • M.S., University of Michigan
    • USDA Forest Service Scientist
    • Research wildlife biologists study vertebrates and habitats they occupy to better understand how to ensure their continued presence in an ever-changing world.
  • Joseph Wunderle, Wildlife Ecologist & Conservation Biologist

    Wildlife
    Front coer of Dr. Joseph Wunderle Collector Card
    • Ph.D., University of Minnesota
    • USDA Forest Service Scientist
    • We study wildlife populations and their relationships with their physical and living environment to identify what might cause populations to increase or decrease.  We apply these research findings to help endangered species’ populations to increase.
  • Ted Weller, Ecologist

    Forests & PlantsWildlife
    Front cover of Ted Weller Collector Card
    • M.S., Humboldt State University
    • USDA Forest Service Scientist
    • An ecologist studies the interaction between animals, their environment, and the weather.  In my work, I study how those interactions change among seasons.
  • Mel Warren, Fisheries & Aquatic Ecologist

    Wildlife
    Front cover of Dr. Mel Warren Collector Card
    • Ph.D., Southern Illinois University, Carbondale
    • USDA Forest Service Scientist
    • As a fisheries and aquatic ecologist, I study fishes and freshwater mussels in their natural habitats to learn about their life cycles, needs for survival, roles in the ecosystem, and how we can conserve them.
