Throughout a analysis keep within the highlands of Colombia carried out as a part of her doctorate, Charlotte Hopfe, PhD pupil underneath the supervision of Prof. Dr. Thomas Scheibel on the Biomaterials analysis group on the College of Bayreuth, has found and zoologically described a brand new species of spider. The beforehand unknown arachnids are native to the central cordillera, not removed from the Pacific coast, at an altitude of over three,500 meters above sea-level. Within the journal PLOS ONE, the scientist from Bayreuth presents the spider she has referred to as Ocrepeira klamt.

“I selected the zoological identify Ocrepeira klamt in honour of Ulrike Klamt, my German trainer at highschool. The keenness with which she pursues her occupation and the curiosity she reveals in her college students and in literature are an inspiration to me,” says Charlotte Hopfe.

The cordillera in Colombia is known for its unusually giant number of species. The habitats of those species are distributed at altitudes with very totally different weather conditions, vegetation, and ecosystems. The Bayreuth researcher has collected and zoologically decided specimens of greater than 100 species of spider in these habitats. In doing so, she was primarily in a area that has solely been accessible to researchers for the reason that finish of civil battle in Colombia in 2016. She found the brand new spider, which differs from associated species within the hanging construction of its reproductive organs, at altitudes of over three,500 meters above sea-level. Within the identification of this and plenty of different spider specimens, Hopfe acquired beneficial help from researchers at Universidad del Valle in Cali, Colombia, with which the College of Bayreuth has a analysis cooperation. Colombia has been recognized as a precedence nation within the internationalization technique of the College of Bayreuth, which is why it maintains shut connections with a number of Colombian universities.

The research of spiders from areas of such varied big climatic and ecological selection can also provide an opportunity to seek out solutions to 2 as but unexplored questions. It’s not but identified whether or not temperatures, precipitation, or different climatic components affect the evolution of spiders, or the properties of their silk. For instance, is the proportion of species with extraordinarily elastic silk within the lowland rainforest greater than within the semi-desert? And it’s also nonetheless unclear whether or not the properties of the silk produced by a species of spider are modified by climatic components. Would a spider residing within the excessive mountains, equivalent to Ocrepeira klamt, produce the identical silk if it had been native to a a lot decrease area of the cordillera? The reply to those questions might present vital clues as to the situations underneath which uncommon spider silks develop.

Alongside related strains, it might even be fascinating to discover whether or not there are spider silk proteins which, attributable to their properties, are much more appropriate for sure purposes in biomedicine and biotechnology than silk proteins at the moment identified. “The better the number of spider silks whose buildings and properties we all know, the better the potential to optimize present biomaterials and to develop new varieties of biomaterials on the premise of silk proteins,” Hopfe explains.

Charlotte Hopfe’s analysis was funded by the German Tutorial Alternate Service and the German Tutorial Scholarship Basis.
