FE: Susan Schwinning talks to Alan Knapp about plant competition in water-limited environments

As part of our new Mechanisms of Plant Competition Special Feature, Susan Schwinning talks to Alan Knapp about plant competition in water-limited environments. Water is the primary factor limiting the growth and productivity of land plants, and fluctuations in plant-available water are ubiquitous in most terrestrial environments, due to variable and unpredictable rainfall. Evolution has produced numerous strategies of compromise between the conflicting goals of maximizing growth and reproduction when water is available and minimizing the risk of mortality when it is not. Because no species is able to pre-empt all opportunities for water and nutrient uptake, many plant species can coexist. However, the mechanisms responsible for making this stable, competitive coexistence possible are often hidden and difficult to study experimentally. Understanding and predicting how plant communities will respond to contemporary climate change remains a challenge to science, but one that can be guided by addressing the fundamental ways in which fluctuations in plant-available water interact with competition, between either adults or seedlings.
