Understanding host range evolution in plant viruses is central for the control of viral
diseases: changes in host range resulting in host switches or host range expansions are at …

The host range of a plant virus is the number of species in which it can reproduce. Most
studies of plant virus host range evolution have focused on the genetics of host–pathogen …

As the rate of spread of invasive species increases, consumer–resource communities are
often populated by a combination of exotic and native species at all trophic levels. In …

Plants suffer from a broad range of abiotic and biotic stresses that do not occur in isolation
but often simultaneously. Productivity of natural and agricultural systems is frequently …

Most eukaryotes harbor a diverse community of parasitic, mutualistic, and commensal
microbial symbionts. Although the diversity of these microbial symbiotic communities has …

Exotic invasive arthropods present an increasing threat to native species, ecosystem
function, crop production, forests, and other natural resources. Importation ('classical') …

Background Multiple infections of the same host by different strains of the same
microparasite species are believed to play a crucial role during the evolution of parasite …

Determining the processes that drive the evolution of pathogen host range can inform our
understanding of disease dynamics and the potential for host shifts. In natural populations …

Donald's ideotype and empirical evidence in cereal and oilseed crops indicate high yield is
associated with less competitive plants. In this study we grew 20 chickpea lines in six …

Background Adaptation of pathogens to their hosts depends critically on factors affecting
pathogen reproductive rate. While pathogen reproduction is the end result of an intricate …
