The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora
Biological Reviews, EarlyView.ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife
Biological Reviews, EarlyView.ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over
