Flower mites spend their lives by stuffing honey in flowers and healing pollen throughout the tropical tropical. In order to move from a certain flower to another flower, these small eight -legged creatures are on the beak of a bee and evacuate into the bird's nostrils during the flight.
When a quick hummingbie drinks a nectar on a flower, the mites run toward their beaks and on the boat, and eventually they move to another flower. However, Callos Garcia Robod, a biologist at Connecticut University, is basically not able to jump in poppy seed -sized mites. How do they feel the presence of birds and adhere to it very fast?
While studying at the Costa Rica La Celva Bioequit Bureau, Dr. Garcia Robbud and his colleagues decided to answer this question.
In a study of the National Science Academy, a study published on Monday found that the team can feel the same kind of modulated electric field created by the hawk, when the wings flip next to the flowers. I did. In addition, these electric fields can quickly lift mites across a small air gap.
This is the first time that the ability to detect electric fields has been discovered by ticks, and this “electric reception” is widely widespread and may be an ecological important, and it is a biologist at Bristol University in the UK. Daniel Robert said. Research on electrical acceptance.
In this study, Dr. Garcia Robbud, biologist Diego Dielic and Constantine Manser have devised experiments to evaluate mites.
One is a mites near the electrode on the grounded copper plate. When the electrodes were turned off or the non -modified electric fields soaked, everything except one of the mites came.
When it turned on within the scope of the electric field emitted from the bee, almost all mites remained and lifted the two forelors toward the electrode.
In the first test, Dr. Garcia Robbudo said, Dr. Garcia Robbburde responded immediately. “I was surprised that the reaction was very obvious and fast,” he said.
In another experiment, it was placed in the glass “Arena”, which had a negative and aggressive edge of animals. When the current turned on, the mites rushed to the actively charged hummingbird in nature and ran to the positively charged side.
Scientists looked closely at the mites's forefoot and found that they contained the same structure as the Halar organ. With each leg, they also found three hairs similar to what spiders used to measure the electric field.
More experiments showed that both the forefoot, which removed both forefoot, did not seem to be attracted to the modified electric field, but one foot modern had one foot.
They also had an anesthetized mites and brought electrodes toward them until the electric field was sufficient to lift animals beyond the 0.5 to 3 mm air gap. Mites can move 150 lengths per second, one of the maximum speed measured among landleaders.
“They are very fast,” said Dr. Garcia Robbud.
He strongly suggests that ticks are actually shining on birds using these fields in nature, and he is moving quickly than their flying host. I said.
Dr. Robert, who was not involved in this research, said that the discovery has raised other interesting questions. By sensing the signal embedded in the electric field of the bee, ticks may be able to learn something about the animals themselves. Can this include a variety of bird size, shape, and flapping frequency, so can it include species -level awareness?
Electrical infections are spread in aquatic animals, but not very common on land. Previous studies show that Maruhana bees detect flower electric fields and use them to evaluate whether flowers have recently been visited by other pollen mediators. So is the hover -free that can do this.
Spiders can also detect the charge in the atmosphere. This is useful for a balloon. Another Arcnide and Himashi bone mites are connected to the host using a static charge.
This white paper is a technical term that is a technical term that is a technical term used when a living thing temporarily hitchhik (a habit different from parasites practiced by ticks). It is the first thing to indicate the electric field used.
Sam England, a biologist in Fool Naturukunde in Berlin, Germany, states:
Flower mites are parasites of the host flower, and exhausts some of the same honey that hungry hawks are consumed. But birds don't seem to care and don't try to remove them.
“Most hummingl has these mites,” said Dr. Garcia Robud.
