Cage Matching: Head to Head Competition Experiments of an Invasive Plant Species from Different Regions as a Means to Test for Differentiation Lortie et al. 2009
Ecotypic differentiation How the population of a species adapts to a particular set of environment conditions Shade-tolerant plantFull-sun plants
Objective Compare inter vs. intra regional competitive ability
For mixed plots
Novelty Compares invasibility of the same species in two different populations Focus on environmental drivers for plant invasion Couples biogeography with population ecology.
Future work? Compare YST in the native range
Questions What is ecotypic differentiation? How does ecotypic differentiation relate to competition? How was the Californian population more successful than the Argentinean population? What are some ways to experimental measure the response of competition in plants?
