Plant Virus Ecology
• examines the ecological roles of plant-associated
viruses in managed and unmanaged ecosystems;
• investigates the reciprocal influence of ecosystem
properties on the distribution and evolution of plant
viruses.

Plant Virus Ecology Sample Questions
•Within a plant species, do virus communities vary predictably according to
environmental gradients?
•How do virus communities vary as a function of environmental gradients
known to be important for vascular plants?
•Do common plant species have more virus species than rare plant species?
•Does 'distance decay' exist in virus communities?
•Do virus abundance distributions conform to expectation from the Unified
Neutral Theory?
•Are virus abundance distributions lognormal?
•Are annuals less likely to have high viral loads?
•Are some habitats more conducive to high viral loads than others?
•Is virus species biodiversity related to plant biodiversity?
•Are native species likely to have higher viral loads than exotic species?
•Are successful invaders relatively virus-free?
•Are exotic plant species more or less prone to infection than native
species?
•Does a diverse plant community confer protection from viruses?
•What is the role of viruses in the maintenance of plant biodiversity?

Plant Virus Ecology and Epidemiology
Epidemiologists: concerned about the consequences of
virus infection in agricultural settings
Ecologists: also interested in the consequences in natural
settings.
Perspectives different, but questions and tools overlap.
