Tick-borne encephalitis virus (TBEV) is a zoonotic flavivirus of growing concern within the One Health framework, as its transmission cycle intricately links wildlife, domestic animals, vectors, and human populations. Its circulation is highly focal, depending on competent tick vectors and reservoir hosts in defined natural foci that can remain stable over decades.

West Nile Virus (WNV), a zoonotic arbovirus with a mosquito-bird transmission cycle, can lead to severe disease in birds and dead-end hosts such as horses and humans. Its distribution has increased worldwide and the reported WNV cases in 2024 in birds and horses even exceeded the previous years. Recently we described the pathogenesis of WNV lineage 2 in-vivo in geese, showing in particular the...

Peatlands are wetland ecosystems that store 44% of terrestrial carbon due to their ability to accumulate organic matter. However, 15% of peatlands worldwide are drained or degraded, threatening the stability of carbon stocks and other ecosystem services that depend on water-saturated conditions. Rewetting peatlands is therefore a key climate mitigation measure. Nevertheless, wet peatlands...
