Queen카지노 게임 컬렉션�s 카지노게임사이트 researcher Barrie Frost and his research collaborators have uncovered the first reliable evidence that some nocturnal insects use the Earth카지노 게임 컬렉션�s magnetic field to navigate during migration.

Each spring, millions of nocturnal Bogong moths (Agrotis infusa) hatch across breeding grounds throughout southeastern Australia before flying over 1,000 kilometres through the dark night to reach a limited number of high altitude caves in the Australian Alps. After a few months of summer dormancy in those cool mountain caves, the moths fly right back to the breeding grounds where they were born.

카지노 게임 컬렉션�When we began this study, we were convinced that the Bogong moth would exclusively use celestial cues in the sky, such as the stars and the moon, for navigation during migration,카지노 게임 컬렉션� says Dr. Frost, Director of the Visual and Auditory Neuroscience Lab at Queen카지노 게임 컬렉션�s. 카지노 게임 컬렉션�This, it turned out, is not the case. We were very surprised when we discovered that these moths could sense the Earth카지노 게임 컬렉션�s magnetic field just like migratory birds.카지노 게임 컬렉션�

For this project, Dr. Frost created an upgraded, computerized flight simulator specifically designed for moths. He used Google Earth to create an accurate moving image of the ground the moths are flying over. When the moth is flying in the simulator, the ground is programmed to always move backward, no matter what direction they choose, which encourages them to keep flying.

To safely suspend the moth in the simulator, the researchers glued a small sensor, called a stalk, to their back, wired the stalk to a computer and then suspended them in the flight simulator using wires. Computers tracked their direction of travel.

Using this simulator, they found the moths카지노 게임 컬렉션� flight direction turned predictably when dominant visual landmarks and a natural Earth-strength magnetic field were turned together. When those two cues were turned in conflicting ways, the moths became disoriented within minutes. The findings led the researchers to conclude that Bogong moths rely on a magnetic sense.

카지노 게임 컬렉션�This is essentially the same strategy we use when hiking in wilderness terrain: we determine our direction with a compass and then look for some distant landmark in roughly the same direction카지노 게임 컬렉션�for instance a mountaintop or a distant tree카지노 게임 컬렉션�and then head for this as we walk,카지노 게임 컬렉션� says Dr. Frost. 카지노 게임 컬렉션�When this landmark is no longer reliable, we again check our direction with the compass and choose a new landmark to orient towards.카지노 게임 컬렉션�

The researchers say they would now like to dissect, in more detail, which visual and magnetic cues the moths use and how they are integrated in the brain. Due to the moths카지노 게임 컬렉션� relatively simple nervous system, they also hope to learn how the insects detect magnetic information, something that has yet to be achieved in any animal.

The research appeared as the lead article in Current Biology and a photo of the Bogong moth appeared on the cover. The Gazette originally reported on Dr. Frost designing the simulator in 2015.
