Drought affects the amount of nectar available for this year. Watch for them this Labor Day weekend as they begin their journey south to their wintering grounds in central Mexico. There may not be as much nectar for them in Oklahoma and Texas; they need the fuel in our Kansas gardens and meadows.

Monarch butterflies are flying south toward central Mexico as a part of their fall migration. Kansas plays a vital role in helping the butterflies on their journey, as states like Oklahoma and Texas experience nectar droughts.

Just out: Another super cool map from our Kansas Applied Remote Sensing Program. We'll be passing this one out at the Kansas State Fair on Sept. 20, the KU Field Station Visitors' Day on Oct. 4, and other events in the coming months.

The Arkansas River Watershed starts in Colorado, ends where the river joins the Mississippi, covers the southern half of Kansas east to west and crosses seven states.

Sometimes, research connections span decades, and sometimes they come with a dog. 🐢🐕

Earlier this year, we were contacted by Dr. Ngaio Richards of Working Dogs for Conservation, who was looking for a classic University of Kansas publication on the natural history of the ornate box turtle (Terrapene ornata).

We were able to provide a PDF of the 1960 study by herpetologist John M. Legler, which contains detailed observations about the turtles' behavior, habitat and seasonal activity. More than 60 years later, that information is helping inform modern conservation work.

And in return, we received two lovely photos of Arly, a Conservation Canine, along with the story behind them. Conservation dogs are trained to use their remarkable sense of smell to help researchers locate wildlife in the field. Arly was helping habitat data researchers collect information and search for an ornate box turtle that had been missing since April — and he found it. 🐾

Understanding an animal's behavior, habitat and seasonal activity can be an important part of this kind of fieldwork. Detailed natural history accounts can provide valuable clues about where a species may be found and the conditions it may be experiencing.

It's a great example of how preserving and sharing scientific knowledge can support new conservation approaches decades after that knowledge was first recorded.

Thanks to Ngaio and to Laura Speight of Sp8 Ecoservices, LLC, for sharing Arly's photos and story with us!

Do you get your water from a Kansas lake (or have you gone swimming in one lately)? We’ve been studying the conditions of Kansas reservoirs for more than 20 years, providing public data about safety and supply.

🚰 In 2006, the Kansas Biological Survey began making bathymetric (lake bottom) maps and taking sediment cores at reservoirs throughout the state. This set a baseline we could use to compare current and historical conditions, which are recorded in the lake sediments themselves.

⛵ In 2017, we moved to the next level of research, monitoring harmful algal blooms (HABs) and water quality. Our researchers have done large-scale experiments to better understand which environmental conditions favor HABs and toxins, and to find ways to mitigate them. This is ongoing.

🚣‍♀️ Now our researchers also take part in the Water Injection Dredging (WID) pilot project at Tuttle Creek Reservoir near Manhattan to test this method of reducing reservoir sedimentation.

🏊‍♀️ All along the way, we’ve made our data available publicly for the website of the Kansas Water Office (they've funded lots of our research).

We live here, and we’re in this for the long haul. (Btw, that's Christine Cornish, a member of our lake assessment team, in the photo.)

We had a great time at the Rocks & Rockets fair in Colby, Kansas, this past Saturday. We brought our giant floor puzzle of Dodge City, a demonstration on mussels native to Kansas waters, a matching game about land use change, giveaways including our Kansas River Watershed maps and notecards, and more.

Researchers Debbie Baker, Dana Peterson and Jennifer Delisle met with visitors of all ages; more than 350 attended. Thanks to the organizers of this annual event!

It takes four to five generations for butterflies to complete the migration from Mexico to the north and back again. How did scientists learn about this?

This interview from South Dakota Public Radio provides a great summary—including info on the place where Monarch Watch picked up the baton in research tracking of the butterflies.

Will Wright, author of the new book Borders of Biodiversity: How Gray Wolves, Monarch Butterflies, and Giant Sequoias Transformed Large Landscape Conservation, tells the story of how Fred and Norah Urquhart of the University of Toronto developed the first tagging/citizen system and spent more than 25 years researching and finally confirming the North American monarch migration to and from overwintering grounds in Michoacán, Mexico.

A great read.

Fifty years ago this August, scientists proved that some monarch butterflies traveled 3,000 miles in a complex migration ritual. Will Wright, Ph.D., explores the complexity of discovery and the challenges of protecting international migration corridors.

Can a recover after a cedar invasion? You’ve seen these trees lining the roadsides and smothering former meadows and pastures.

🐦 Eastern redcedars (Juniperus virginiana) have long been used as windbreaks and serve as an important food source for wild birds (which spread the seeds).

🌑 But they can overtake open ground quickly, and redcedar invasion can be particularly damaging to native prairies because the tree’s wide base and thick foliage quickly shade out native grasses and wildflowers.

🌱 Falling needles also change soil pH, making it more alkaline. This binds soil nutrients such as phosphorus, depleting resources for other plants.

🌳 Once established, redcedar can remain a dominant species for decades before being gradually replaced by hardwoods such as oaks and hickories.

☀️ Once we clear a never-plowed prairie of redcedars, what steps should we take to help it recover—and what should we reasonably expect in terms of recovery?

We'll have some answers in the near future. Holly Andres, graduate student in Ecology and Evolutionary Biology, is in the beginning stages of research on these very questions. She’s been awarded a fellowship from the Grassland Heritage Foundation for her planned work. More to come.

Holly's advisor is Ben Sikes, a senior scientist here at the Kansas Biological Survey and a KU professor.

Can maintain high yields with half the nitrogen fertilizer routinely used?

🌽 KU researchers are working on that goal with collaborators at Colorado State University. Agricultural changes happen in stages.

🌽 Maggie Wagner, Kansas Biological Survey associate scientist and KU associate professor of Ecology and Evolutionary Biology, along with Joel Swift, postdoc in Maggie’s lab, and Kai Sarwinski, undergraduate researcher, have been in Fort Collins, Colo., working with their colleagues.

🌽 The researchers collected samples and data from hundreds of maize (corn) plants, with the goal of identifying the genetic codes of those that perform better than expected when grown without fertilizer.

🌽 They're especially interested in the roles of roots and root-associated microbes, which requires uprooting the plants.

🌽 The overall goal of the project is to breed maize hybrids that maintain high yield when receiving only 50 percent of the standard dose of nitrogen fertilizer. The project is funded by the Dept. of Energy.

We had a wet spring in eastern Kansas this year; other areas were wildly variable. Are precipitation extremes changing?

💧 A new interactive map allows users to explore data and patterns in across the state. (Link in comments)

🌧️ It's based on rainfall records from 1895 through 2023 and looks specifically at annual and seasonal extremes.

💦 Data shows an increase in recurring wet extremes since about 1980.

You can search for and download historical data by:
👉 Groundwater Management District;
👉 county;
👉 reservoir catchment basin; and
👉 Regional Advisory Committee (Kansas Water Office = funded the research).

The Kansas Hydroclimate Extremes app was developed by David Weiss and Jude Kastens of our Kansas Applied Remote Sensing Program. It’s based on study led by Sam Zipper of the Kansas Geological Survey; collaborators were David, Jude and KU faculty members from the departments of geography and atmospheric science and geology.

Your monthly check-in for July at the West Campus Pocket Prairie, a teaching space planted by our researchers and maintained with help from the KU grounds crew. There's a lot of noise from machinery here, but this small restoration and the creatures in it seem to be thriving. 🦋🌻🌼
