Data from: A comparative survey of the frequency and distribution of polymorphism in the genome of Xenopus tropicalis

Chris Showell, Samantha Carruthers, Amanda Hall, Fernando Pardo-Manuel De Villena, Derek Stemple & Frank L. Conlon
Naturally occurring DNA sequence variation within a species underlies evolutionary adaptation and can give rise to phenotypic changes that provide novel insight into biological questions. This variation exists in laboratory populations just as in wild populations and, in addition to being a source of useful alleles for genetic studies, can impact efforts to identify induced mutations in sequence-based genetic screens. The Western clawed frog Xenopus tropicalis (X. tropicalis) has been adopted as a model system...

Data from: Potential fitness tradeoffs for thermal tolerance in the intertidal copepod Tigriopus californicus

Christopher S. Willett
Thermal adaptation to spatially varying environmental conditions occurs in a wide range of species, but what is less clear is the nature of fitness trade-offs associated with this temperature adaptation. Here, populations of the intertidal copepod Tigriopus californicus are examined at both local and latitudinal scales to determine whether these populations have evolved differences in their survival under high temperature stress. A clear pattern of increasing high temperature stress tolerance is seen with decreasing latitude,...

Data from: Data archiving is a good investment

Heather A. Piwowar, Todd J. Vision & Michael C. Whitlock
Funding agencies are reluctant to support data archiving, even though large research funders such as the National Science Foundation (NSF) and the National Institutes of Health acknowledge its importance for scientific progress. Our quantitative estimates of data reuse indicate that ongoing financial investment in data-archiving infrastructure provides a high scientific return.

Data from: Hybrid breakdown weakens under thermal stress in population crosses of the copepod Tigriopus californicus.

Christopher S. Willett
The outcome of hybridization can be impacted by environment conditions, which themselves can contribute to reproductive isolation between taxa. In crosses of genetically divergent populations, hybridization can have both negative and positive impacts on fitness, the balance between which might be tipped by changes in the environment. Genetically divergent populations of the intertidal copepod Tigriopus californicus have been shown to differ in thermal tolerance at high temperatures along a latitudinal gradient. In this study a...
