The use of eDNA in the reconstruction of present and past polar vertebrates’ populations by Rodrigo Goldenberg-Barbosa, Anna Donato, Dafne Anjos, Cesar Amaral

“…Our results show how the Artic region is well represented with several studies focusing on vertebrates, being the second most researched group of organisms (19%), only behind plants, and with several studies related to the development of new approaches and methodologies for the use of eDNA from cold regions being published in the last years. In opposite, the Antarctic eDNA science on vertebrates is still poorly developed, with the vast majority of studies focusing on microbial life; therefore, the Antarctic region still remains with a great potential for the research development in vertebrates and the effects of the past and recent climate changes on their populations.…”

“…The aim of this study was to assess the pathogenic potential of E. coli strains from the polar regions of the Earth, based on the analysis of the genomes of these bacteria from typical ornithogenic ecosystems of the Arctic and Antarctic. Materials and methods. The study used collections of E. coli isolated from ornithogenic biological material during expeditions to high latitude areas of the Arctic (archipelagos of Novaya Zemlya, Franz Josef Land, Svalbard) and Antarctic (Haswell Archipelago). 16 cultures associated with avian E. coli (12 polar and 4 temperate strains) were selected for genome-wide sequencing using BGI technology. …”
