Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

Public lands in the U.S. are managed with two goals in mind, protecting biodiversity and

providing people with recreational opportunities, a chance to connect with nature. But sometimes

those two goals are at odds, especially if recreation, activities like hiking or hunting,

disrupts wild animals enough to alter their use of those landscapes.

Indeed, several years ago, a study done in California found that hikers had a negative impact

on wildlife.

And that kind of sounded a bit of an alarm to us as wildlife biologist and as people who like to go hiking ourselves.

Wildlife biologist Roland Kay's of the North Carolina Museum of Natural Sciences at NC State University.

We were pretty worried that this problem was as bad as it seemed from that study and as widespread, and was widespread,

that there could be a real conflict between outdoor recreation and wildlife conservation.

To find out, Kay's and his team enlisted the help of more than 350 volunteer citizen scientists,

who deployed camera traps at nearly 2,000 sites within 32 protected areas

in six different states.

Roughly half of the areas allowed hunting and half did not.

What they discovered was something of a relief.

We found relatively minor impacts of hunting and hiking on wildlife.
