The distribution of Phytophthora cinnamomi in the Americas is related to its main host (Persea americana), but with high potential for expansion

Phytophthora cinnamomi is among the most destructive plant pathogens that affect many host plants in different ecosystems. Economically important hosts of this pathogen include avocado (Persea americana), and oomycete may cause large-scale epidemics. This study analyzed potential geographic distribution P. (pathogen) (host), relation to multiple Americas. Niche overlap between were also evaluated, using a multistep process ecological niche modelling MaxEnt algorithm. similarity populations related examined. As complement, tool was designed visualize risk avocado. Results showed randomly distributed environmental space, but pathogenwas narrower than its principal host. The largely function niches. Areas with grow could present low cinnamomi, given invasiveness pathogen, they be affected future.
