Reconstruction of Araucaria araucana cone production reveals warming intensifies regionally synchronized masting [PDF]
EcosphereThe reproduction of many long‐lived plants is highly variable and synchronized, known as masting. Masting is a key driver of plant regeneration dynamics and has cascading effects on food webs and carbon and nutrient fluxes through ecosystems.
