This file contains phenotypic and fitness data on naturally-recruiting Boechera stricta plants in 5 transects. Jill Anderson collected these data at the Carpenter Meadow site in 2010. The data file was created in Text Wrangler.

This file contains data from the experiment at Carpenter Meadow to assess natural selection on flowering in local genotypes. Jill Anderson collected data in the field in 2010. Analyses included size at planting (number of leaves) and cohort as fixed effects, and row nested within block as random eff

Interspecific hybridization may enhance the capacity of populations to adapt to changing environments, and has practical implications for reforestation. We use genomewide estimates of admixture and phenotypic traits for trees in a common garden to examine the extent and direction of gene flow across

Gene flow from transgenic crops allows novel traits to spread to sexually compatible weeds. Traits such as resistance to insects may enhance the fitness of weeds, but few studies have tested for these effects under natural field conditions. We created F2 and F3 crop-weed hybrid lineages of genetical

Specialization is common in most lineages of insect herbivores, one of the most diverse groups of organisms on earth. To address how and why specialization is maintained over evolutionary time, we hypothesized that plant defense and other ecological attributes of potential host plants would predict

We examined patterns of genetic differentiation at isozyme loci in natural populations of Ipomopsis aggregata, for which distances of gene flow had been previously estimated. Using genetic neighborhood areas based on direct estimates of gene flow to define subpopulations, we found that FST values (t

The total number of viable, undamaged seeds released by a plant provides an estimate of female reproductive success (RS). I outline a method for analyzing pollinator-mediated selection based on partitioning female RS into four multiplicative components: number of flowers, pollen received per flower,

Estimates of realized gene flow and pollen dispersal to stigmas in the same natural populations of Ipomopsis aggregata subsp.

ABSTRACTDominantly coarse‐grained, shallow‐marine, metasedimentary rocks of the Early Proterozoic Uncompahgre Group (UG) record periods of shoaling and drowning on different temporal scales that are attributed to episodic long‐term oscillations in relative sea‐level with superimposed shorter duratio

Future correlational studies must explicitly consider phylogeny and should also be supplemented by detailed studies of particular transitions to dioecy - studies of the sort that have clarified analogous issues such as heterostyly.
