Ecology, Not Host Phylogeny, Shapes the Oral Microbiome in Closely Related Species
Maraitou, Markella; Forsythe, Adrian; Fellows Yates, James A.; Brealey, Jaelle; Warinner, Christina; Guschanski, Katerina (Peer reviewed; Journal article, 2022)Host-associated microbiomes are essential for a multitude of biological processes. Placed at the contact zone between external and internal environments, the little-studied oral microbiome has important roles in host ... -
Genomic analyses show extremely perilous conservation status of African and Asiatic cheetahs (Acinonyx jubatus)
Prost, Stefan; Machado, Ana Paula; Zumbroich, Julia; Preier, Lisa; Mahtani-Williams, Sarita; Meissner, Rene; Guschanski, Katerina; Brealey, Jaelle; Rodríguez Fernandes, Carlos; Vercammen, Paul; Hunter, Luke T. B.; Abramov, Alexei V.; Plasil, Martin; Horin, Petr; Godsall-Bottriell, Lena; Bottriell, Paul; Dalton, Desire Lee; Kotze, Antoinette; Burger, Pamela Anna (Peer reviewed; Journal article, 2022)We live in a world characterized by biodiversity loss and global environmental change. The extinction of large carnivores can have ramifying effects on ecosystems like an uncontrolled increase in wild herbivores, which in ... -
Genomic insights into the conservation status of the world’s last remaining Sumatran rhinoceros populations
von Seth, Johanna; Dussex, Nicolas; Díez-del-Molino, David; van der Valk, Tom; Kutschera, Verena E.; Kierczak, Marcin; Steiner, Cynthia C.; Liu, Shanlin; Gilbert, Marcus Thomas Pius; Sinding, Mikkel-Holger S.; Prost, Stefan; Guschanski, Katerina; Nathan, Senthilvel K. S. S.; Brace, Selina; Chan, Yvonne L.; Wheat, Christopher W.; Skoglund, Pontus; Ryder, Oliver A.; Goossens, Benoit; Götherström, Anders; Dalén, Love (Peer reviewed; Journal article, 2021)Small populations are often exposed to high inbreeding and mutational load that can increase the risk of extinction. The Sumatran rhinoceros was widespread in Southeast Asia, but is now restricted to small and isolated ... -
Inference of natural selection from ancient DNA
Dehasque, Marianne; Ávila-Arcos, María C; Díez-del-Molino, David; Fumagalli, Matteo; Guschanski, Katerina; Lorenzen, Eline D.; Malaspinas, Anna-Sapfo; Marques-Bonet, Tomas; Martin, Michael David; Murray, Gemma G.R.; Papadopulos, Alexander; Therkildsen, Nina Overgaard; Wegmann, Daniel; Dalén, Love; Foote, Andrew (Peer reviewed; Journal article, 2020)Evolutionary processes, including selection, can be indirectly inferred based on patterns of genomic variation among contemporary populations or species. However, this often requires unrealistic assumptions of ancestral ... -
The oral microbiota of wild bears in Sweden reflects the history of antibiotic use by humans
Brealey, Jaelle; Leitão, Henrique; Hofstede, Thijs; Kalthoff, Daniela C.; Guschanski, Katerina (Peer reviewed; Journal article, 2021)Following the advent of industrial-scale antibiotic production in the 1940s,1 antimicrobial resistance (AMR) has been on the rise and now poses a major global health threat in terms of mortality, morbidity, and economic ...
