FNR 2020 Year in Review: The Research

FNR Research Breakthroughs
Hellbender eggs at Mesker Park Zoo breedingDr. Rod Williams and his hellbender lab team were instrumental in the success of Mesker Park Zoo in getting captive hellbenders to breed naturally.

The state of Indiana also selected the Eastern Hellbender project to highlight as part of the Association of Fish and Wildlife Agencies (AFWA) national effort.


Dr. Songlin Fei analyzed 16 years of U.S. Forest Service forestry inventory analysis regarding the impact of the emerald ash borer on the destruction of ash forests and concluded that in impacted areas, young trees are dying before they can reach their reproductive stages.


Dr. Shao co-supervised a research team composed of several electrical and computer engineering (ECE) undergraduates, who have accomplished real-time measurements of tree attributes, including diameter at breast height (DBH) computation and lowest branch detection. The team successfully demonstrated the capability to automatically measure 1,000 trees in Martell Forest within 36 minutes by driving through a red oak plantation. The driving speed can be doubled or tripled when measuring a walnut plantation with clear ground conditions.
Major Grants
Map of Coreyon ReefDr. Tomas Hook and his research team will be providing a checkup on the Coreyon Reef Project in Saginaw Bay in Lake Huron through a new grant from the Michigan Department of Natural Resources and the Environmental Protection Agency.

Dr. Jacob Hosen is part of a team which will be studying how hydrology and plant community diversity can be modulated to maximize nutrient retention and minimize production of greenhouse gasses from wetlands, after receiving a $500,000 grant from the USDA’s National Institute of Food and Agriculture (NIFA).

Dr. Bryan Pijanowski and post-doctoral research associate Dr. Kristen Bellisario’s proposal regarding “Sensor technologies for real-time monitoring of mosquito populations through heat maps in India” was selected as one of four to receive the 2020 Shah Family Global Innovation Lab Seed Grant.

He also is part of a multi-disciplinary effort to study the relationships Mongolian herders have with their landscapes through the lens of sound. His team of ecologists, social scientists and ethnomusicologists, received $750,000 from the National Science Foundation for the four-year project.
Dr. Linda Prokopy earned support for two new projects: “Understanding of Persistence of Cover Crop Use: Lower Wabash,” and also a social science assessment of the obstacles and opportunities for meeting nutrient management goals.

Inyo California TowheeDr. Andrew DeWoody will be studying the genetics of the Inyo California Towhee, a potentially endangered bird species.

Assistant professors Mo Zhou and Jingjing Liang will be part of a collaborative study with the University of Kentucky on “Enhancing the Awareness, Knowledge and Understanding of Sustainable Maple Syrup Production Practices Among Current and Potential Maple Syrup Producers.” The duo has been awarded a $100,000 grant from the United States Department of Agriculture - Acer Access and Development Program for their portion of the study. – Zhou, Liang Earn Maple Syrup Industry Grant

Dr. Liz Flaherty is part of a newly funded grant from the National Science Foundation: “Collaborative Research: The Ecological Basis of Hunting and Meat Sharing in Female Savanna Chimpanzees,” an interdisciplinary project, which assesses female biased hunting. It is part of the HUNTRESS (hunting, nutrition, tool use, reproductive ecology, and meat sharing in savanna chimpanzees) project. Flaherty will be leading the stable isotope component of the project.
