SOU biologist receives NSF grant for grasshopper research
(Ashland, Ore.) — Southern Oregon University biologist Jacob Youngblood has been awarded a three-year, $422,183 grant from the National Science Foundation to study how insects respond to two aspects of climate change – rising air temperatures and declining plant nutrients – potentially improving pest management strategies and forecasts of insect-related damage nationwide.
The study will focus on migratory grasshoppers, which consume as much as 20% of available forage from U.S. rangelands each year for losses estimated at about $393 million.
“This project will investigate how temperature and nutrition jointly affect the most damaging rangeland pest in the United States,” said an abstract of the NSF grant. ”By combining fieldwork, laboratory experiments and computer simulations, the research will improve ecological forecasts and inform pest management strategies that support national food security.”
The project is also expected to provide opportunities for SOU students to participate as paid researchers. The work will be conducted partly by students enrolled in Youngblood’s courses in environmental physiology and biogeography. The NSF-funded project – “How temperature-nutrient interactions affect the physiology and ecology of an insect herbivore” – is scheduled to begin Aug. 1.
“This work has the potential to significantly improve how we manage national rangelands in a changing climate,” Youngblood said. “If we can predict grasshopper outbreaks before they happen, we can act proactively to minimize damage to crops and forage.
“Just as important, the project will train SOU students – many of whom are the first in their families to attend college – in research design, data analysis and science communication, preparing our graduates to tackle scientific challenges in their careers and communities.”
The project will test competing hypotheses for how the combination of temperature conditions and nutrient availability affect the biology of grasshoppers. It will involve a combination of computer simulations, experiments in artificial laboratory environments and field experiments conducted at The Farm at SOU.
“Together, this integrative approach will advance general theory on how organisms forage in multidimensional environments and how those foraging decisions scale up to affect physiology and ecology,” the abstract of the NSF grant project said.
Youngblood, an animal physiologist and ecologist, joined the SOU Biology Department as an assistant professor in 2022. His research interests involve predicting the impacts of climate change on insect populations. He teaches courses on the principles of biology, comparative animal physiology and biogeography.
He earned a bachelor’s degree in biological sciences from Clemson University and a doctorate in biology from Arizona State University.
