"We're not saying this is an excellent outcome for the status or the persistence of this native mosquito," said Tyson Research Center director Kim Medley.

As you’re swatting at swarms of mosquitoes this spring, take comfort in this fact: Our bloodsucking foes have their own parasites.

The tiny waterborne parasites only infect mosquitoes — but not every species is susceptible.

The invasive Asian rock pool mosquito, first found in Missouri in 2005, appears to be virtually immune to a protozoan parasite in Missouri. Biologists at Tyson Research Center now say this invasive mosquito acts like a vacuum, sucking up parasites that attack a native mosquito species.

Julia Berndt kneels on the forest floor and picks up a crushed eggshell from an experimental bird nest.

The Webster Groves High School senior has spent nearly three months working at Washington University’s Tyson Research Center near Eureka. The summer program pairs St. Louis-area students with scientists who help them design their own independent-research projects.

Berndt is studying how controlled fires — also known as prescribed burns — affect the predators that eat bird eggs.

Most people hope to avoid ticks when they take a walk in the woods.

For biologists at Washington University’s Tyson Research Center, however, attracting ticks is the goal.

In a recent study, Tyson researchers collected thousands of lone star ticks in the Missouri Ozarks. The results point to an interesting pattern: the number of ticks found in an area is closely related to the topography, or physical features, of the landscape.

Volunteer Lisa Houska is hunkered down next to a tall cyclone fence at the Endangered Wolf Center in Eureka. She’s peering at a hillside, observing a handsome pair of thick-furred Mexican wolves and their three pups that were born last year.

“We’re watching Sibi and Lazarus. This is their second breeding season,’’ Houska whispers.

For two hours on this unseasonably warm winter morning she’ll sit motionless, trying not to disturb the family. She’s hoping to witness another successful courtship between mom and dad.

Ozark glade restoration project heats up at Tyson

Researchers are conducting controlled burns this week at Washington University’s Tyson Research Center southwest of St. Louis.

The burns are part of a project to study how to restore Ozark glades – rocky forest clearings with native species that resemble those of the desert southwest.

Washington University ecologist and project lead Tiffany Knight says fire is a natural part of glade ecosystems.

This article first appeared in the St. Louis Beacon, June 10, 2009 - A learning center in Eureka may soon be recognized as one of the greenest buildings in North America.

The cedar-sided Living Learning Center sits on the grounds of Washington University's Tyson Research Center at the end of a winding road, within 2,000 acres of forest, prairies, ponds and savanna. The center, built at a cost of $1.4 million, is poised to be the first building in the United States and Canada to meet the strict standards of the Living Building Challenge.
