Flowering time is an important life history trait in plants that often
affects fitness. The optimal time to flower may be influenced by
trade-offs between flowering time and growth-related traits and is thus
likely to differ among habitats. Because flowering-time differences
between populations can also reduce gene flow, understanding the factors
that contribute to variation in flowering time among closely adjacent
populations that experience gene flow is of particular interest. Plant
adaptation to different edaphic environments provides some of the best
examples of adaptive divergence at small spatial scales, and often
coincides with flowering-time shifts. The current study addresses the
causes of flowering-time differences in two populations of Leptosiphon
parviflorus that are locally adapted to adjacent serpentine and sandstone
soils despite moderate levels of gene flow and close geographic proximity.
Field reciprocal-transplant studies and watering manipulations in the
greenhouse demonstrate the contribution of both the genotype and the
environment to observed flowering-time differences. The plasticity of
flowering time in response to soil type appears to be driven by
differences in soil moisture. In addition, selection on flowering time was
measured in both soil types across 4 years of study using a set of F5
advanced-generation hybrids and found to differ between the habitats.
Therefore, both selection and plasticity contribute to flowering-time
differences between these populations and thus have likely played an
important role in the initiation and/or maintenance of adaptive divergence
in this system.
Soil Volumetric Water Content Jan 27-June 18 2015This file includes the
raw voltage readings as well as the calculated volumetric water content
readings from four different sensors for each soil type (serpentine and
sandstone) at Jasper Ridge Biological Preserve. Two replicates were placed
at two different locations on each soil type (see README file for a
diagram for the approximate locations of each
sensor).VWC_2015.csvGreenhouse flowering time data for serpentine and
sandstone populationsData collected at the Michigan State University
greenhouse on serpentine "Serp" or sandstone "Sand"
soil in two treatments- "Dry" vs. "Control".
'Pop' indicates the population source, 'Initial Flat'
refers to the flat/position of the individual before being assigned to a
treatment. 'treatment_flat' refers to the flat replicate (nested
within treatment- either 1 or 2). 'Plant' is a unique number for
each plant on each flat, 'Date_Planted' is the day that each
individual was transplanted, 'Flower_Day' is the first day that
each plant was observed to flower (Day 0=first day of transplant/Feb 11),
and the first plant to flower was on Day 27 (corresponding to March
10).Parents_gh.csvFlowering time of the serpentine and sandstone
populations in the fieldThis data was collected on the parental
populations (serpentine and sandstone) on their native soil types at
Jasper Ridge Biological Preserve during years 2012-2015. Here,
'Rep' refers to the replicate plot (nested within year and soil
type). Years 2012-2013 only had one replicate plot on each soil type. The
'Flat_transplant' is the day each individual was transplanted to
the flat filled with field soil, and the 'Field_transplant' is
the day each individual was transplanted from the flat to the field.
Field.Row and Field.Column are the Row/Column positions for each plant in
the field plots, 'Edge' plants were directly on the outer edge
of each plot, while 'Inner' plants include everything else. The
date of first flower is listed in addition to the day of first flower. Day
#1 is the day the first plant flowered in that
year.Parents_field.csvFlowering time and fitness (survival, number of
flowers, number of fruits) for the F5 advanced-generation hybrids on each
soil type (serpentine or sandstone) during 2012-2015This data was
collected at Jasper Ridge Biological Preserve during years 2012-2015.
Here, 'Rep' refers to the replicate plot (nested within year and

include everything else. The date of first flower is listed in addition to
the day of first flower. Day #1 is the day the first plant flowered in
that year. 'Surv_flr' is whether or not the plant survived to
flower, and 'NumFlowers' and 'NumFruits' is the number
of flowers or fruits each plant produced.F5_selection.csv
