Surely once insects have brought pollen to a flower, then plant-plant interaction is over? Not so, says Gerardo Arceo-Gómez, who argues that heterospecific (or other plants’) pollen arriving in a flower might affect plant diversity.
Community structure is most likely regulated by both elevation and soil nitrogen availability.
How do plants occupy niches within their communities? New research shows key roles for two features: habitat filtering and limiting similarity.
