Understanding wildlife responses to novel threats is vital in counteracting biodiversity loss. The emerging pathogen () causes dramatic declines in European salamander populations, and is considered an imminent threat to global amphibian biodiversity. However, real-life disease outcomes remain largely uncharacterized.

- Habitat anthropization negatively impacts global biodiversity, but some species show adaptive life-history responses, like increased reproduction, to cope with these changes.
- The study focused on the yellow-bellied toad and utilized a large dataset of over 21,000 individuals from various European populations to examine the effects of anthropogenic environments on their survival and reproduction.
- Results indicated that while adult toads had lower survival and shorter lifespans in human-modified habitats, their increased reproductive output compensated for these losses, helping to maintain stable population growth rates despite habitat alterations.
Starting in 2010, rapid fire salamander (Salamandra salamandra) population declines in northwestern Europe heralded the emergence of Batrachochytrium salamandrivorans (Bsal), a salamander-pathogenic chytrid fungus. Bsal poses an imminent threat to global salamander diversity owing to its wide host range, high pathogenicity, and long-term persistence in ecosystems. While there is a pressing need to develop further research and conservation actions, data limitations inherent to recent pathogen emergence obscure necessary insights into Bsal disease ecology.

Mitigating this hazard requires a thorough understanding of the pathogen's disease ecology that is driving the extinction process. Here, we monitored infection, disease and host population dynamics in a Belgian fire salamander (Salamandra salamandra) population for two years immediately after the first signs of infection.

Presence of the chytrid fungus Batrachochytrium salamandrivorans at new locations and in urodeles of different species expands the known geographic and host range of the fungus and underpins its imminent threat to biodiversity.
