Asexual Evolution and Forest Conditions Drive Genetic Parallelism in Phytophthora ramorum

Microorganisms, 2020
It is commonly assumed that asexual lineages are short-lived evolutionarily, yet many asexual organisms can generate genetic and phenotypic variation, providing an avenue for further evolution.

Environmental variables associated with Nothophaeocryptopus gaeumannii population structure and Swiss needle cast severity in Western Oregon and Washington

Ecology and Evolution, 2019
The environment has a strong influence on the abundance and distribution of plant pathogenic organisms and plays a major role in plant disease. Climatological factors may also alter the dynamics of the interactions between plant pathogens and their hosts.

Importance of local and long-distance Heterobasidion irregulare aerial basidiospore dispersal for future infection centres in thinned red pine plantations in Quebec

The Forestry Chronicle, 2017
Heterobasidion irregulare is a basidiomyceteous forest pathogenic fungus which causes a root disease capable of killing large trees. Infection probability is proportional to the density of aerial basidiospores infecting freshly cut stumps. The purpose of
