Plants must precisely time flowering to capitalize on favorable conditions. Although we know a great deal about the genetic basis of flowering phenology in model species under controlled conditions, the genetic architecture of this ecologically-important trait is poorly understood in non-model organisms. Here, we evaluated the transition from vegetative growth to flowering in Boechera stricta, a perennial relative of Arabidopsis thaliana. We examined flowering time QTLs using 7,920 recombinant inbred individuals, across seven lab and...

Brown trout microsatellite data (61 loci). The data set consists of samples from three wild brown trout populations in Western Jutland, Denmark, along with samples from two hatchery strains used for stocking. The samples of wild trout populations consist of contemporary samples (2000-2006). Moreover, two of the populations are also represented by historical samples from 1943-1956. See Hansen et al. (2010) for further details. The data file is in MSA format [Dieringer D, Schlotterer C...

Previous studies using partial regression Mantel tests of matrix correspondence on within-island geographic variation in the color pattern of the Tenerife (Canary Islands) lacertid lizard (Gallotia galloti) support natural selection for different north--south climatically determined biotopes but do not support any historical cause. However, tests on the DNA phylogeny based primarily on population data from 57 localities on Tenerife support the hypothesis that there were populations on two putative precursor islands that have come into...

Phylogenetic relationships were reconstructed for salamanders of the plethodontid subfamily Desmognathinae to examine evolution of morphology, ecology, and life history. Mitochondrial DNA sequences encoding 12S and 16S ribosomal RNA and the valine transfer RNA provided 259 phylogenetically informative sites from approximately 1,200 nucleotide positions for 21 specimens representing 15 species and subspecies. These data were analyzed in conjunction with 13 morphological and reproductive characters to generate phylogenetic hypotheses. The directly developing terrestrial desmognathines Phaeognathus hubrichti...

The switch from feeding to nonfeeding larvae is an ecologically important transformation that has evolved on several separate occasions within the echinoids. In each case, this life history transformation has been accompanied by extensive changes in larval morphology. A phylogenetic approach is used here to reconstruct these morphological changes, to begin asking why they have taken the particular forms observed, and to assess the degree of parallel transformation in separate cases. Both traditional character mapping...
