New species of snakes and arthropods
Discovered new species of snakes and arthropods
It would seem, at the dawn of the new Millennium, it is difficult to find new species of animals, but yet scientists continue to surprise us. Research is successful quite often: for example, in South East Asia were found unique flying snakes. but in Indonesia – the new Gecko. And again found unknown fauna.
Long-term field and laboratory work by a group of zoologists led by Omar Torres-Carvajal (Museum of Zoology, Pontifical Catholic University of Ecuador) led to the discovery in the forests in northwestern Ecuador a new species remnevidnyh thick-headed serpent, which was named Imantodes chocoensis.
To allocate a new view that allowed features of the structure of the head. Later DNA analysis confirmed the hypothesis and allowed us to determine the closest relatives of snakes. They were members of the species that live in the Amazon basin on the other side of the Andes. “One possible explanation for the differences Imantodes chocoensis and its closest relative is that the uplift of the Andes have divided the original population into two parts, each of which has evolved into a separate species,” said Dr Torres-Carvajal.
Remnevidnyh thick-headed snakes live in Mexico and Argentina and are different from other snakes of the New World with a very thin body, disproportionately slender neck, big eyes, and a dumb head. They live in trees and hunt frogs and lizards at night.
In addition to new snakes were found previously unknown arthropods. A group of scientists from the University of Navarra and a group of speleologists headed by Floren with Fedrico (Catalan Association of Biospeleology) found three new species of springtails in caves in Teruel (Spain) that belong to one of the most ancient groups of animals on our planet.
“Studying fauna in the caves allows us to expand our knowledge of biodiversity. Springtails are found organisms that were completely isolated for thousands of years. Climate change has not touched them,” explained Enrique Baquero, who carried out a taxonomic study along with Rafael Jordan (University of Navarra).
Three new species of springtails belong to different groups and are phylogenetically very distant from each other. They have been named Pygmarrhopalites maestrazgoensis, P. cantavetulae and Oncopodura fadriquei.
