Data from: Postglacial climate and fire-mediated vegetation change on the western Olympic Peninsula, Washington

Daniel G. Gavin, Linda B. Brubaker & D. Noah Greenwald
The mode and tempo of forest compositional change during periods of rapid climate change, including the potential for the fire regime to produce non-linear relationships between climate and vegetation, is a long-standing theme of forest ecological research. In the old conifer forests of the coastal Pacific Northwest, fire disturbances are sufficiently rare that their relation to climate and their ecological effects are poorly understood. We used a 14,700-year high-resolution sediment record from Yahoo Lake on...

Data from: The genetic basis of a rare flower color polymorphism in Mimulus lewisii provides insight to the evolutionary mutation spectrum

Carrie A. Wu, Matthew A. Streisfeld, Laura I. Nutter & Kaitlyn A. Cross
A long-standing question in evolutionary biology asks whether the genetic changes contributing to phenotypic evolution are predictable. Here, we identify a genetic change associated with segregating variation in flower color within a population of Mimulus lewisii. To determine whether these types of changes are predictable, we combined this information with data from other species to investigate whether the spectrum of mutations affecting flower color transitions differs based on the evolutionary time-scale since divergence. We used...

Data from: Thermal adaptation and acclimation of ectotherms from differing aquatic climates

Shawn R. Narum, Nathan R. Campbell, Kevin A. Meyer, Michael R. Miller & Ronald W. Hardy
To elucidate the mechanisms of thermal adaptation and acclimation in ectothermic aquatic organisms from differing climates, we used a common-garden experiment for thermal stress to investigate the heat shock response of redband trout (Oncorhynchus mykiss gairdneri) from desert and montane populations. Evidence for adaptation was observed as expression of heat shock genes in fish from the desert population was more similar to control (unstressed) fish and significantly different (P ≤ 0.05) from those from the...

Data from: Genomic patterns of introgression in rainbow and westslope cutthroat trout illuminated by overlapping paired-end RAD sequencing

Rapid and inexpensive methods for genomewide single nucleotide polymorphism (SNP) discovery and genotyping are urgently needed for population management and conservation. In hybridized populations, genomic techniques that can identify and genotype thousands of species-diagnostic markers would allow precise estimates of population- and individual-level admixture as well as identification of ‘super invasive’ alleles, which show elevated rates of introgression above the genomewide background (likely due to natural selection). Techniques like restriction-site-associated DNA (RAD) sequencing can discover...

Data from: The population structure and recent colonization history of Oregon threespine stickleback determined using restriction-site associated DNA-sequencing

Julian Catchen, Susan Bassham, Taylor Wilson, Mark Currey, Conor O'Brien, Quick Yeates & William A. Cresko
Understanding how genetic variation is partitioned across genomes within and among populations is a fundamental problem in ecological and evolutionary genetics. To address this problem, we studied the threespine stickleback fish, which has repeatedly undergone parallel phenotypic and genetic differentiation when oceanic fish have invaded freshwater habitats. While significant evolutionary genetic research has been performed using stickleback from geographic regions that have been deglaciated in the last 20 000 years, less research has focused on...

Data from: Association between integration structure and functional evolution in the opercular four-bar apparatus of the threespine stickleback, Gasterosteus aculeatus (Pisces: Gasterosteidae)

Heather A. Jamniczky, Emily E. Harper, Rebecca Garner, William A. Cresko, Peter C. Wainwright, Benedikt Hallgrimsson & Charles B. Kimmel
Phenotypes may evolve to become integrated in response to functional demands. Once evolved, integrated phenotypes, often modular, can also influence the trajectory of subsequent responses to selection. Clearly, connecting modularity and functionally adaptive evolution has been challenging. The teleost skull and jaw structures are useful for understanding this connection because of the key roles that these structures play in feeding in novel environments with different prey resources. In the present study, we examined such a...

Data from: Oligo-Miocene climate change and mammal body size evolution in the northwest United States a test of Bergmann's Rule

John D. Orcutt & Samantha S. B. Hopkins
Whether or not climate plays a causal role in mammal body-size evolution is one of the longest-standing debates in ecology. Bergmann's Rule, the longest-standing model addressing this topic, posits that geographic body-mass patterns are driven by temperature, whereas subsequent research has suggested that other ecological variables, particularly precipitation and seasonality, may be the major drivers of body-size evolution. While paleoecological data provide a unique and crucial perspective on this debate, paleontological tests of Bergmann's rule...
