The Gulf of Mexico dead zone is predicted to be a near record size in 2019. By the end of summer, the hypoxic region at the mouth of the Mississippi River is expected to occupy over 22,000 square kilometers—an area the size of Massachusetts. The culprit? Nitrogen-based fertilizers applied to crops across the Midwest that… Read more »
In a grassy clearing between crop hectares at the Kellogg Biological Station LTER, Dr. Nick Haddad, Principle Investigator, stares into the dark recesses of a bee box, set a few feet off the ground. The research team places the bees here while they’re still in cocoons. When they hatch, the bees gather fluorescent yellow, powdered… Read more »
Dr. Doug Landis waded into a soybean field in Michigan’s Kellogg Biological Station LTER Site. Bending down in the September heat, he carefully turned over leaf after leaf. After a few seconds he stopped, “Here they are!” I crouched down to my heels, bringing my face close to the rough underside of the leaf. Dr…. Read more »
Puffy clouds skirt the late summer sky, occasionally dumping a shower on our heads while Dr. Doug Landis and I walked between the crop rows at the Kellogg Biological Station (KBS) in Michigan. Breezes ruffled the soybean leaves like waves, but few insects or birds zipped through the sky above the crops. Near the corn… Read more »
Researchers took advantage of a 24-year experiment maintained by the Kellogg Biological Station LTER to assess the possibility that cultivation practices might drive evolution of less-cooperative microbes.
How do you begin to approach wicked problems, those that span socioeconomic and ecological spheres, when solutions involve multiple and varied stakeholders? Researchers at the Kellogg Biological Station LTER began to tackle one of U.S. agriculture’s greatest challenges, excess nitrogen pollution, by hosting “The N Roundtable,” to improve the flow of information through a farming landscape that has changed dramatically in the past few decades.
Credit: Jim, the photographer. CC Y 2.0To reduce the risk of being eaten, prey animals may change their behavior (by staying hidden during certain hours, for example) and adapt physiologically. Although these responses help prey survive in the short-term, they also suppress their ability to move and reproduce. By studying insect responses to the risk… Read more »

A typical warm summer night is complemented with the familiar glow of fireflies and the light spectacle they create darting around and lighting up the night sky. However, the timing of these light shows might be affected by environmental changes. In order to better understand the life history of the firefly, researchers from the Kellogg Biological Station (KBS) LTER investigated the phenological patterns of fireflies from 2004-2015 to determine what explains the variability observed in their mating season.
Some bacteria become less cooperative with their plant hosts under long-term nutrient additions, finds new research by Jen Lau, an ecologist at the Kellogg Biological Station (KBS) LTER, and her collaborator Katy Heath at the University of Illinois. “A decade ago, no one was thinking about the idea of rapid evolution—the kind you could see… Read more »
