<i>Phytophthora ramorum</i> - a pathogen linking network epidemiology, landscape pathology and conservation biogeography.

Pautasso, M.
<i>Phytophthora ramorum</i> is a generalist plant pathogen that has been subject to a remarkable amount of research activity. One decade after its description, this oomycete now affects a wide range of hosts in both North America and Europe, both in the wild and in ornamental plant trade (e.g., <i>Camellia</i>, <i>Rhododendron</i>, <i>Pieris</i>). Research on the biology, epidemiology and management of <i>P. ramorum</i> has not only rapidly expanded, but has also become increasingly interdisciplinary. In this overview, three examples of interdisciplinary collaboration concerning <i>P. ramorum</i> are presented: (1) network epidemiology (the application of network theory to epidemiology), (2) landscape pathology (the use of landscape ecology tools in the study of regional outbreaks of tree pathogens) and (3) conservation biogeography (a biogeographical perspective in conservation biology). Building on these approaches, three-way collaboration among network epidemiologists, landscape pathologists and conservation biogeographers (as well as e.g., molecular biologists, social and climate change scientists) is now needed to improve our understanding and management of the <i>P. ramorum</i> emergency, and many other challenges to plant health worldwide.
