The role of functional traits and trade-offs in structuring phytoplankton communities: scaling from cellular to ecosystem level.

abstract：:Natural ecosystems are shaped along two fundamental axes, space and time, but how biodiversity is partitioned along both axes is not well understood. Here, we show that the relationship between temporal and spatial biodiversity patterns can vary predictably according to habitat characteristics. By quantifying seasonal...
