THE University of Rey Juan Carlos (Urjc) Collides a study on the arachnidal fauna of underground ecosystems of Carmona (Seville)which revealed the presence of a kind of exotic spider, 30 Mogeaof origin Asian.
The study is part of a research project led by Fernando Cortés-FossatiMember of the ecological evolutionary group of the Biodiversity and conservation area of the Eurjc and in which the Autonomous University of Barcelona, the European University of Madrid, the Iberian group of Arancology and the Andalusian Association of underground explorations have also participated.
The main objective of this project was to analyze the native fauna of the Cavernícola arthropods in the underground aqueducts of Carmona (Seville), since there is a large scientific lagoon around this type of ecosystems. To deal with this lack of information, the team of specialists made an expedition to aqueducts of Roman origin.
This type of Nestícid spiders is characterized by living Wet places How they can cuevas. Since this place is part of the protected historical heritage, a Meticulous manual capture strategy Do not damage the structures of the monument.
This technique was carried out by two of the Co -Autors of the Labor, belonging to the Andalusian Association of underground explorations and the European University. Subsequently, an taxonomic analysis of the champions was performed.
The results of this work, published in the Arachnology of the international magazine, determined that it was Howaia Mogera, a very small type of spider of Asian origin which is probably already established in the area.
According to this study, he has extended from his native area for more than 50 years, perhaps thanks to Flow of goodsthat theAnd made it possible to reach more than 13 countries around the world.
Fernando Courteouus-Fossai highlights that “it is essential Continues to monitor this species up closesince there are still questions to answer. “
“One of the most important is to know if it is a Invasive speciesThat is, that it can produce adverse effects on the ecosystems in which it is introduced or if it is simply exotic. It should be considered that our country has a large number of endemic underground species, many of which have threatened, “he says.
