Life after death: site pre-emption by the remains of Poa annua

J. Bergelson

Research output: Contribution to journalArticlepeer-review


Randomly distributed Capsella bursa-pastoris and Senecio vulgaris were introduced into plots with either a random or a patchy distribution of Poa. Seedling numbers in the following generation were 4-6 times as high for Capsella and Senecio when Poa was patchily rather than randomly distributed, due to increased emergence or survival of seedlings in areas with a low density of dead Poa adults. Interference by dead grass blades was responsible for high seedling mortality. -from Author
