Description

Vegetative dormancy, that is the temporary absence of aboveground growth for ≥ 1 year, is paradoxical, because plants cannot photosynthesise or flower during dormant periods. We test ecological and evolutionary hypotheses for its widespread persistence. We show that dormancy has evolved numerous times. Most species displaying dormancy exhibit life‐history costs of sprouting, and of dormancy. Short‐lived and mycoheterotrophic species have higher proportions of dormant plants than long‐lived species and species with other nutritional modes. Foliage loss is associated with higher future dormancy levels, suggesting that carbon limitation promotes dormancy. Maximum dormancy duration is shorter under higher precipitation and at higher latitudes, the latter suggesting an important role for competition or herbivory. Study length affects estimates of some demographic parameters. Our results identify life historical and environmental drivers of dormancy. We also highlight the evolutionary importance of the little understood costs of sprouting and growth, latitudinal stress gradients and mixed nutritional modes.

Notes

Main data file and legend
This Excel file includes two spreadsheets. The first, labelled "Data file", includes the data needed to run the main mixed modeling in our paper. The second, labelled "Legend", describes the variables. Please note that commas and ambiguous punctuation have been avoided so that the files can be exported as CSV files. Also, please note that, due to conservation concerns and legal requirements, population locations have been withheld. Instead, we present the latitude and longitude of populations, both rounded to the nearest 5 degrees.
