Giant flying spiders of the Guru species love big cities. A new study finds that their ability to relax in stressful situations may be the reason why. – Science News (Trending Perfect)

The Great Epic Invasive Guru Spiders Skydiving through the air isn't over yet. A new study has found that the 4-inch-long creatures have a truly different build, with hearts that can handle loud, rumbling noises. Major cities.

University of Georgia researcher Andy Davis made the discovery while conducting cardiac stress tests on guru spiders and their cousin, the golden silk spider. The research was published in the journal physiological entomology On Monday, he found that this type knows how to relax and stay calm when placed in situations that raise their heart rate.

The study says that the Goro spider, also known as Trichonyphylla clavata, “is known to weave its webs not only in natural green spaces but also in cities and towns, often on buildings and human dwellings.” “Trichonyphylla spiders’ responses to stress can be described as ‘homeostatic’, which may influence their ability to survive in habitats with frequent disturbances.”

Davis and his team evaluated the physiological responses of the Goro spiders and golden silk spiders and compared them with those of another pair of similarly sized and closely related species, the garden spiders and the striped garden spiders.

The researchers recorded the spiders' baseline heart rates while they were resting and inactive, and then recorded their heart rates after they were restrained under electronic sensors for 10 minutes.

“When all spider species were exposed to the new constraint stress, their heart rates increased, an expected response that other spider researchers have observed,” the study says. “However, there were differences between species in the magnitude of this increase, and in how the responses progressed over the 10-minute period.”

The researchers said the garden spiders, which belong to the genus Argiope, showed “distinct periods of fluctuation during constraint” and were even found to struggle against the constraint. On the other hand, the Goro spiders and their golden silk cousins ​​were “less fluctuating and more balanced.” They were also observed to enter a state of diapause for more than an hour after being stressed, meaning they essentially froze during that time.

The tests “begin to paint a picture of how the invasive goro spider and its cousin the golden silk spider have a unique way of tolerating new stressors, which may be why they are able to occupy human-made landscapes,” the researchers said, noting that other spider species in their family line may share this trait, although this needs further investigation.

Guru spiders have been making headlines for years as they continue to spread along the East Coast. The spiders, which originated in Asia, are believed to have been first introduced to northern Georgia around 2010. They have since been found in nearly a dozen other states. In December, Davis told the New York Times that New York is “right in the middle of where you like to be.” The spiders are expected to show up in the New York tri-state area this summer, though there have been no reports of that happening.

“They seem to be fine living in the city,” he told the newspaper, adding that they have been seen hanging out on street lamps and telephone poles, where “normal spiders wouldn't be able to live.”

The latest findings may not definitively prove that the spiders' relaxed behavior is behind their “affinity for urban environments,” the study says, adding that more research is needed. However, they do add weight to Davis' theory. Search from Februarywhich also found that Guru spiders don't necessarily mind the increased noise and vibrations that come with city life.

“These Guru webs are everywhere in the fall, including next to busy roads, and the spiders seem to be able to make a living there,” Davis said of his previous research. “For some reason, these spiders seem to be tolerant of urban areas.”

Alexa Schultz, a University of Georgia student and co-author of the study, Agreed“It seems that Guru spiders would not be shy about building a web under a traffic light or in an area where you would not imagine a spider would be found,” he said.

But don't worry – although spiders are venomous, they pose no danger to humans, although they may raise your heart rate more than theirs.
