Insecticides Similar to Nicotine Widespread in Midwest Insecticides similar to nicotine, known as neonicotinoids, were found commonly in streams throughout the Midwest, according to a new USGS study. This is the first broad-scale investigation of neonicotinoid insecticides in the Midwestern United States and one of the first conducted within the United States. Effective in killing a broad… Robert J. Korpella 07/31/14
Bees Able to Spot Which Flowers Offer Best Rewards Before Landing Bumblebees are able to connect differences in pollen quality with floral features, such as petal color, and so land only on the flowers that offer the best rewards, according to a new study by researchers at the University of Exeter. The study used bumblebee foragers housed under controlled conditions to… Robert J. Korpella 07/31/14
The Secrets of Owls’ Near Noiseless Wings Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence. “Owls possess no fewer than three distinct physical attributes that are thought to contribute to their silent flight capability: a comb of stiff… Robert J. Korpella 11/26/13
River Otters Show Evidence of Banned Toxins Researchers in Illinois discovered something very disturbing: river otters have been exposed to dangerous chemicals and pesticides that were banned decades ago. In some cases, the concentrations of chemicals in the otters’ livers exceeded otters examined before the compounds were banned. The Illinois Department of Natural Resources gathered the remains… Robert J. Korpella 10/16/13

The Dollar Benefit of Stream Revitalization Here’s a refreshing bit of news. Rather than focus on the costs of cleaning up a polluted stream, the U.S. Geological Survey (USGS) celebrated the jobs, and the millions of dollars in value the restoration project contributed to a local economy. This stream renovation project didn’t happen in the Ozarks,… Robert J. Korpella 08/16/13
Ticks Carry the Heartland Virus, Too A mysterious virus that afflicted two Missouri farmers in 2009 was confirmed as a disease transmitted to humans through tick bites. The two Missouri men were admitted to the hospital after suffering from high fevers, fatigue, diarrhea, and an extreme drop in white blood cell counts. Since the symptoms resembled… Robert J. Korpella 07/25/13
Stream Biodiversity Impacted by Pesticides Pesticides, primarily those used in agriculture, are among the most investigated and most regulated of pollutants. Recent studies have concentrated on the influence of pesticides on the biodiversity of aquatic habitats. International researchers recently demonstrated biodiversity losses of 27 to 42 percent in streams across the globe as a result… Robert J. Korpella 06/21/13
Insecticides Lead Aquatic Insects to Starvation Neonicotinoids are a class of insecticides that are chemically related to nicotine. These insecticides affect the nerve synapses of insects, and neonicotinoids are popular for their solubility in water. Plants absorb the chemical, which is often applied to the soil to reduce its chances of drifting through the air. However,… Robert J. Korpella 05/17/13
Pan’er Mountain I got to spend some time with an old friend not long ago. Many years had sailed between visits, brought on by a lack of time, other priorities, whatever the reason. The beginning of our conversation was tenuous. Some of the old familiarity had been erased with the passing of… Robert J. Korpella 05/03/13
Exposure to Fine Traffic Pollution Particles Increases Heart Disease Risk Over the years, a number of studies described various associations between road traffic and heart disease. Last year, one such study even demonstrated a link between traffic noise and the probability of suffering a heart attack. The latest study shows that long-term exposure to the type of fine particulate matter… Robert J. Korpella 04/18/13
Spring Peepers I look forward to those harbingers of spring each year. Spring peepers occupy a little hollow near my house, and they start calling in mid, sometimes early March each year. My friend and fellow Master Naturalist, Bob Kipfer, captured some excellent footage of a peeper peeping. If you’re anxious to… Robert J. Korpella 03/22/13
Hog Farm Threatens the Buffalo In the 1960s and early 1970s, Dr. Neil Compton and a host of others fought the U.S. Army Corps of Engineers about that organization’s plan to dam the Buffalo River. Dr. Compton and his team won that fight. But a new threat looms for the Buffalo River. C&H Hog Farms… Robert J. Korpella 03/14/13
The Child in Nature Miranda Anderson grew up with a respect for nature. Her parents led her in that direction. She had her own kayak by the time she was five, and she floated it in the ocean—a lot. Miranda hopes to become a marine biologist one day but for now, she’s in demand… Robert J. Korpella 03/08/13
Kids Have a Lot to Teach Parents About the Environment Sometimes without even realizing it, a child can directly impact the attitude and behavior of her parents with respect to the environment. Researchers have now quantified how environmental education is passed from a young generation to an older one, and how that new knowledge influences behavior. While the study took… Robert J.

Floating the Bird Count The Great Backyard Bird Count was last weekend. It rolls around the middle of February each year, and it’s a great excuse to grab an extra cup of coffee and a recliner, then sit back and enjoy the comings and goings of birds in your backyard or neighborhood. Count the… Robert J. Korpella 02/22/13
Mood Enhancing Drugs Impact Fish, Too Water treatment plants only filter out so much material. Mineral levels, for example, are typically much higher downstream of treatment plants than they are elsewhere. That fact is driven by salt expelled by the body, but not captured during treatment. A larger issue is the accumulation of pharmaceuticals passed through… Robert J. Korpella 02/15/13
New Fish Species Named for Roosevelt, Carter, Clinton, Gore and Obama Biologists identified five new fish species recently, and named them after former presidents and a vice-president: Teddy Roosevelt, Jimmy Carter, Bill Clinton, Al Gore and Barack Obama. Two species are found in the waters of Arkansas, Missouri and Oklahoma. Scientists chose these political leaders for their environmental records. All the… Robert J. Korpella 11/29/12
Poor Air Quality Means Poor Test Scores for Senior Citizens No wonder so many seniors settle in the Ozarks after retirement. Or in the desert southwest, or even in parts of Florida for that matter. New research demonstrates that areas of high air pollution, something we do not experience much here in the Ozarks, often leads to cognitive dysfunction in… Robert J. Korpella 11/21/12
Alien Invaders Red fire ants, thousand cankers disease, kudzu, zebra mussels and emerald ash borers are just a few of the invasive species that cost the U.S. up to $130 billion annually in both damage and preventative measures. Add to that a recent study discovering that 47 percent of firewood bundles purchased… Robert J. Korpella 10/24/12
Tick Bites Causing Unusual Allergic Reactions Beside that nasty, itching wound left behind, we most feared Lyme disease or Rocky Mountain spotted fever spread by ticks. Now scientists have linked another problem with tick bites: severe allergic reactions to eating red meat. The lone star tick, named for the single white dot on its back, is… Robert J. Korpella 08/31/12
The Scoop on Dirt We’ve become a society addicted to cleanliness. Grocery cart corrals have sanitizing wipes available, and hand sanitizers are at nearly every desk and in many purses. Not that cleanliness is all bad, but the National Wildlife Federation (NWF) says a little dirt is actually a good thing for children. Building… Robert J. Korpella 08/24/12
Keeping the Watershed Clean A butterfly flaps its wings in China, creating a thunderstorm in Chicago. That’s the essence of the “butterfly effect,” where small changes in one location can make a big impact somewhere else. While that example might stretch our thinking, one that’s closer to home is how actions upstream in our… Robert J. Korpella 08/17/12
Brown Recluse Spiders Make Appearance Two venomous spiders inhabit the Ozarks. One of them has sought shelter this summer by heading indoors. A number of people throughout the region reported seeing brown recluse spiders in greater numbers this year. Experts say that may be a result of a prolonged heat wave and drought that hit… Robert J. Korpella 08/17/12
The Cicada Killer Wasp A brightly colored wasp about two inches long with a menacing stinger is enough to make many people head back indoors. But cicada killer wasps are paired with mild manners to go along with their threatening appearance. At least they are docile where humans are concerned. It’s a different story… Robert J. Korpella 08/10/12
Perseids About to Heat Up If you’ve wished upon a falling star this summer, you’ve probably caught one of the Perseid meteors. This summer spectacular is already underway, but the peak will occur this weekend. The International Meteor Organization predicts 50 to 60 meteors per hour during the mornings of August 11, 12 and 13.… Robert J. Korpella 08/08/12
When It Comes to Navigation, a Trout’s Nose Knows Wild rainbow trout can swim upriver and downstream, investigate feeder creeks and return to their place of birth with nearly flawless navigation. A keen sense of smell and great eyesight account for some of their directional prowess, but scientists have recently isolated what could be the biggest catch of all—magnetic… Robert J. Korpella 07/20/12
The Great Backyard Bee Count Thanks to the efforts of nearly 100,000 citizen scientist volunteers, Gretchen LeBuhn and her team of researchers assembled what is now the largest single body of information on bee activity in North America.

Songbirds and Outdoor Cats - A Deadly Combination Non-native species almost always exact a toll on the natives. Large crayfish overpower smaller varieties, Japanese beetles decimate tree leaves, kudzu engulfs about anything that isn’t moving too fast, and both feral and house cats significantly diminish songbird populations. The Audubon Society says that over 100 million songbird deaths are… Robert J. Korpella 06/08/12
Humidity a Clue to Where the Nectar Is Plants and pollinators have co-evolved over millions of years. During that time, plants developed myriad means of attracting bees, flies and other animals to spread pollen and keep the plant species thriving. In similar fashion, pollinators developed specialized methods of collecting plant nectar, as well as a little pollen while… Robert J. Korpella 05/31/12
Pesticide Makes Bees Finicky Eaters Links between pesticides and honeybee health continue. Researchers at the University of California San Diego discovered that even small doses of a common crop pesticide turned bees into finicky eaters, and inhibited their ability to communicate food sources to the rest of the hive. Bee colonies throughout the world have… Robert J. Korpella 05/25/12
Never a Dull Day Fishing I hadn’t wet a line in a while, so my plan was to ply the waters of Capps Creek for a couple of hours in search of a few rainbow or brown trout. Capps is a location where I’ve either had great success catching fish, or left without as much… Robert J. Korpella 05/18/12
Do Genes Rule Behavior? Age determines stereotypical roles worker honeybees assume. When they are only a few days old, they take on the tasks of feeding the brood and producing beeswax to seal cells in the hive where larvae develop. After a week, she moves on to other tasks, such as grooming other bees… Robert J. Korpella 04/26/12
Talking with the Animals When Dr. Doolittle longed to converse with animals, I’m not sure he had worms in mind. But a team of California Institute of Technology scientists got down in the dirt to discover a communication technique used by nematodes, one of the most abundant animals on Earth. Scientists already discovered that… Robert J. Korpella 04/19/12
Wild Edibles of Missouri Ever wonder which plants are edible and which to avoid? The Missouri Department of Conservation has captured a now out of print book, Robert J. Korpella 04/13/12
Honey Bees Have Ability to Self-Medicate Researchers at North Carolina State University recently discovered that worker honey bees became healers when the bees’ hives were attacked by a harmful fungus. The fungal infection triggers bees to increase levels of antifungal plant resins. “The colony is willing to expend the energy and effort of its worker bees… Robert J. Korpella 03/30/12
Nest Cams Cornell’s Lab of Ornithology has set up a couple of web cams on bird nests. One features red-tailed hawks that built a nest on top of an 80-foot tall stadium light, while the other one keeps watch on blue herons that constructed a nest on a dead white oak tree… Robert J. Korpella 03/29/12
A Spring Snake Find I don’t have a fear of snakes. But I won’t be the first one in line to hold one either. In fact, I may not get in line at all. If I see one in the wild, I am curious enough to get within a safe distance to study it.… Robert J. Korpella 03/23/12
March Planets in View If you’ve scanned the heavens at night this month, you probably couldn’t help notice a very bright “star” in the western sky. That’s actually sunlight reflecting off the clouds that surround our planetary neighbor, Venus. It’s proximity to Earth makes Venus glow brilliantly in the night sky. The other bright… Robert J. Korpella 03/16/12
Open Pipes Threaten Birds After discovering the remains of hundreds of birds in an uncapped pipe, Audubon California advocates sealing off exposed pipes. That advice is worth following here in the Ozarks as well. In spring, birds often locate small openings they can use to build a nest. Some species, such as bluebirds, depend… Robert J. Korpella 03/09/12
Ovenbird Decline Linked to Invasive Species In the upper Midwest, ground-nesting ovenbirds are in decline as a result of an unlikely invasive species: earthworms. Ovenbirds, which are part of the warbler family, visit the Ozarks throughout the summer months. They are difficult to spot in forested areas, but their loud song which resembles “teacher, teacher, teacher”… Robert J. Korpella 03/02/12
Rare Fungus Kills Endangered Rattlesnakes Eastern massasauga rattlesnakes are not native to the Ozarks. Their closest proximity to our region is a small section of northeastern Missouri, and parts of southern Illinois. But they are significant because a fungus not normally seen in the wild presents an unexpected threat that has killed several snakes already.… Robert J. Korpella 02/24/12
Crystal Bridges Art Museum Featuring a story about an art museum may seem unusual for an outdoors website, but Crystal Bridges is anything but typical for an art museum.
