0:00.0 | Understanding the human body is a team effort. That's where the Yachtel group comes in. |
0:05.8 | Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years. |
0:11.0 | Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program. |
0:19.6 | To learn more about Yachtolt, visit yawcult.co. |
0:22.7 | .jp. That's Y-A-K-U-L-T.C-O.J-P. When it comes to a guide for your gut, count on Yacult. |
0:34.1 | This is Scientific American 60-second science. I'm Annie Sneed. |
0:38.3 | Populations of frog, salamanders, and other amphibians are declining around the world, |
0:43.8 | even in protected areas like U.S. national parks. |
0:47.3 | Ecologists needed a simple method to track the animal's numbers. |
0:51.3 | Now, researchers have found an effective way to keep tabs on amphibians, |
0:56.2 | using that concert and party favorite, glow sticks. Green glow sticks to be specific. |
1:02.0 | What we do know is that their eyes are particularly sensitive to green light. |
1:06.9 | David Munoz, a PhD candidate in the Ecology program at Penn State University. |
1:11.8 | To test the idea, Munoz and colleagues set up minotraps with and without glow sticks at a dozen vernal pools in Center County, Pennsylvania. |
1:20.0 | The critters gather the pools to breed. For a month, they trapped and tracked numbers of the Jefferson Salamander, the spotted salamander, the wood frog, |
1:28.1 | and the eastern red spotted newt. |
1:30.1 | Right before we leave for the day around 4 p.m., we'd activate the glowstick and hang it on the little |
1:35.9 | minnow trap, come back the next day to see what we got. |
1:39.4 | Traps with glowsticks were vastly more productive. |
1:42.0 | We were really surprised by how strong of an effect our |
1:46.5 | glowsticks had on our captures. So by just putting a glowstick in one of these minnow traps, |
1:54.1 | we increased the capture rates for our spotted salamanders and our Jefferson salamanders |
