The evolutionary consequences of domestication
Poppy

Poppy is an ancient domesticated plant. Humans have selected it for medicinal use, food and flowers. PhD Student Pranoy is studying the how suites of plant traits have changed in response to this domestication.

Parasitoids

Plants and their pest herbivores have of course evolved due to domestication. Parasitoids that reply on herbivores in agricultural systems have also evolved. Long ago, for her PhD, Saskya studied the evolution of parasitoid wasp foraging behavior where its host is found on cultivated cabbage vs where it is found on wild mustard.
