This dataset contains information related to the paper “Strong natural selection
during plant restoration favors an unexpected suite of plant traits” by Sarah Kulpa
and Elizabeth Leger, published in Evolutionary Applications. The first worksheet
contains data collected from an outdoor F1 common garden, the second worksheet
contains data from an F2 common garden, and the third worksheet has seed weights
from seeds produced during the second common garden (F3 seeds, which were not
planted). Terminology is consistent with that in the paper, where methodology is
described.
Data were collected by Sarah Kulpa, Elizabeth Leger, and Sandra Li. Questions about
this data file should be directed to: Elizabeth Leger, [email protected], University
of Nevada, Reno, 1664 N. Virginia Street, Reno, NV 89557, 775 784 7582.
Column headings:
Family: refers to seeds from a single plant. F1 families consist of seeds collected
from one of two field sites (East Humboldt and Gopher; there were no families for
seeds originally used in restoration). F2 families consist of seeds collected from the
F1 common garden, and F3 families are the progeny of F2 plants.
Seed source: indicates whether seeds are from the two field sites or the original
seeds used in restoration.
F1, F2, or F3 seed weight (mg): the weight of an individual seed. In the F2 garden, 4
additional seeds were weighed but not planted for each family so each family would
have 8 seeds weighed; the bottom four seeds per family were not planted in the
field.
Germination date: the date plants were observed to emerge from the ground.
Number of leaves, spikelets, plant height (cm): self explanatory.
End of season biomass (g): the dry mass of the vegetative part of the plant.
Total seed production (g): the total weight of seeds produced. Not all plants that
made spikelets produced seeds.
Flower date 2010: In the F1 garden, the flowering date of each plant was monitored
in the second year of growth.
Basal area (cm2): The size of the base of the plant, calculated by multiplying plant
length by width.
Missing data are indicated with “.”
