Recording of presentation at Evolution 2022. The same presentation was given at ASM 2022. Abstract: The phylogeny and other aspects of the evolutionary history of the Neotropical cat genus Leopardus have long been shrouded in uncertainty, partly owing to an overwhelming abundance of genealogical discordance in this group. We employ whole-genome s...
Article
Darwin's fox is an opportunistic omnivorous predator native to Chile classified as Endangered by the IUCN Red List. Habitat use by Darwin's foxes can be negatively affected by the presence of free-ranging dogs that range freely across native and non-native habitats and can be a source of fox mortality. The objective of this study was to analyze the...

Feline paramyxoviruses are found all over the world. They are suspected of being involved in chronic diseases of the urinary tract in domestic cats. Research at our institute led to the discovery of new paramyxoviruses in cats. The diversity of these viruses and their molecular pathogenesis are the focus of my research.

Goal: A disease surveillance programme in the field to evaluate the risk of outbreaks in both the insular and continental range of the species. Compare pathogen prevalence in areas with different levels of anthropogenic intervention where Darwin's foxes occur. We have extended our research to also sample other species of carnivores that share their ecosystem with this threatened canid. Additionally, we are sampling domestic dogs and vaccinate them to avoid spill-over to wild carnivores. Finally we have created a serum and tissue bank with samples from this species in order to have samples available for retrospective studies and to share them with other institutions.
