Why do steamers have strips? Perhaps to throw insects off – Chemainus Valley Courier


Zebra strips are silent – especially for insects.

That is the conclusion of scientists from the University of Bristol and the University of California in Davis who wore horses in black and white clothes coats to help determine why zebra gets strips.

The researchers found that fewer horses were landed on the clogged horses and those without a strip coat, suggesting that zebra straps could offer protection from insects that can suck blood that can spread disease.

"The ability to reduce this to spin on the zebra coat because of strikes may affect the visual system of the horse insects during their last time," said Martin How, a joint research at the University of Bristol. "Stripes can sweep aviation in some way once they are close enough to see their low resolution eyes."

From a distance, the insects were attracted to both the horses and the zebra, with the same number of insects growing around both types of animals. But when the insects arrived closer, things get discipline. The insects plunged less frequently on the zebra and the horses covered in strip coats.

"Once they come closer to the zebra, however, they tend to fly past or enter them," said Tim Caro, a professor at the University. Davis Wildlife, Fish and Conservation Department. "This suggests that strips can interfere with the abilities of insects to have controlled landing."

The work, which is reported in the Public Library of Science UN magazine, is trying to answer one of the oldest questions in zoology – why do zebraras have strips? Charles Darwin received his theories. So British naturalist Alfred Russel Wallace.

But the British and California scientists tried to explore that question by studying horses and zebra at the British Live Live Hill, working with zoos in Europe on conservation for zebra. That gave a controlled environment where the horses could be worn and carefully viewed to test the theory.

"There's one of those research pieces that you say, why did not someone have done this?" & # 39; Tim Woodfine, conservation director at Marwell Wildlife in southern England said. He did not take part in the study. "It's simple and tidy. I think it's a big piece of work," he said.

Commenting on The Press Associated on Thursday, an expert on the vision of animals, there are reasons for being "quite exciting" about the research, and said scientists help him to understand what is happening in the minds of aviation .

The insights have wider implications for technology such as unloaded cars, inspired by the vision of the insects. If strokes are disrupted by air, they can also interfere with car systems without a driver, according to How.

"What we needed to do is get our mind into the eye of the fly," How he said. "They have very different eyes from us."

Erica McAlister, the older curator of insects and pests at the Museum of Natural History in London, said that the research contributed information to a topic discussed by scientists.

"We've been arguing about zebra strips for 75 years," said McAlister, who was not part of the study.

But there are also human requests. As he says from now on, he wore strips when riding his bicycle during the flight season.

I hope Caro that the study will underline the wonders that can still be found in the natural world.

"If we can try to blow the public's appreciation of the wonders of nature, they will be less prisoners about its destruction," he said. "That is my hope.
