Earlier flowering did not alter pollen limitation in an early flowering shrub under short-term experimental warming

Abstract In animal pollinated plants, phenological shifts caused by climate change may have important ecological consequences. However, no empirical evidence exists at present on the consequences that flowering phenology shifts have on the strength of pollen limitation under experimental warming. He...
