An Interesting Method Used by Brown Tree Snakes to Climb (Video). Until this time, four different movement abilities of snakes, one of the cold-blooded creatures of nature, were recorded. However, a fifth movement was observed in the US-affiliated island of Guam.
In a new article published in the journal Current Biology, snakes’ sidewinding, linear, lateral undulation, and “concertina”In addition to either (the movement of snakes tüm ortaklık or tying with some parts of their body, pushing or pulling other parts of their body in the direction of movement) a fifth mobility it was described more.
Fifth mobility observed in snakes
This new biçim of climbing discovered in snakes, cement movement (lasso locomotion). The authors of the study say the lasso movement helped this invading snake species access resources that would otherwise be inaccessible. Although the lasso technique özgü evolved to help snakes climb trees, snakes use this method. electric poles It also uses it to climb structures such as.
These snakes, which were introduced to the island of Guam in the 1940s and 50s, caused the extinction of many bird species on the island. Only Micronesian Cattle and a bird that nests in caves remained. These snakes not only cause trouble for the birds on the island, but also do a lot of damage to the infrastructures. Due to this snake species, power cuts is happening. Therefore, it is very important for scientists to discover which structures these snakes cannot climb.
The researchers tested whether they could protect them from snakes by installing roller deflectors under bird nests on electric poles. This method özgü previously been used to keep other snakes and raccoons away from bird nests. Ecologist Thomas Seibert found that the deflector worked at first, but later using the lasso technique He says they saw the brown tree snake and they were shocked.
Researchers noticed that five different snakes used this technique. Working on the movement abilities of snakes Bruce Jayne says the lasso created by the snakes compresses the roller to create friction and prevent slipping. Bruce Jayne explains the movement of the brown tree snake as follows:
“The small bends in the lasso spiral have two functions. First; it provides a mechanism to tighten the spiral by using the largest muscle group in the snake’s body. Latter; little by little they move the snake upwards. “
Of course, this lasso technique requires snakes to make intense physical effort. Snakes perform these upward movements very slowly and take frequent breaks. Although it is not known whether this technique is used by other species, its use stated to be likely.
