Data from: Geographic variation in Megalorchestia californiana allele frequencies may be caused by winter rather than summer temperatures

John H. McDonald & JH McDonald
There are many allozyme polymorphisms with latitudinal clines, for which selection by climate is one obvious explanation. Both warm summer temperatures and cold winter temperatures could plausibly impose selection on enzyme polymorphisms, but because summer and winter temperatures are usually geographically correlated, there has been little attempt to use patterns of geographic variation to discriminate between these possible selective factors. The glucose-6-phosphate isomerase and mannose-6-phosphate isomerase allozyme polymorphisms in the amphipod crustacean Megalorchestia californiana have...

Data from: Population genetic data of a model symbiotic cnidarian system reveal remarkable symbiotic specificity and vectored introductions across ocean basins

Daniel J. Thornhill, Yu Xiang, Min Zhong, Scott R. Santos & D. Tye Pettay
The Aiptasia-Symbiodinium symbiosis is a promising model for experimental studies of cnidarian-dinoflagellate associations, yet relatively little is known regarding the genetic diversity of either symbiotic partner. To address this we collected Aiptasia from 17 localities throughout the world and examined the genetic diversity of both anemones and their endosymbionts. Based on newly-developed SCAR markers, Aiptasia consisted of two genetically-distinct populations, one Aiptasia lineage from Florida and a second network of Aiptasia genotypes found at other...
