TL;DR: It is proposed that multiple intraspecific hybridization events may have created especially potent conditions for the selection of a noxious invader, and may explain differences in genetic patterns among North and South America populations, inferred differences in demographic processes, as well as morphological differences previously reported from common garden experiments.

TL;DR: The results suggest that local adaptation may play a role in the success of C. solstitialis as an invasive weed and evaluated FST values against QST (FST/QST analysis) and found evidence for possible selection on plant height and leaf length in the non-native regions.

TL;DR: This study examines 482 expressed sequence tag contigs that encode putative membrane transporters in the economically important red seaweed Porphyra and identifies 30 trees that support the expected monophyly of red and green algae/plants and 19 that show evidence of endosymbiotic/horizontal gene transfer involving stramenopiles.

TL;DR: Cytochrome B sequences and allozymes reveal complex patterns of molecular variation in dusky salamander (Desmognathus) populations in eastern Tennessee, recognizing that it may never be possible to reconcile species limits with patterns of phylogeny, morphology, and gene exchange in these salamanders.

TL;DR: Analysis of mitochondrial (cytochrome b) nucleotide sequences, nuclear allozyme markers, and morphometric characters to investigate species boundaries and phylogenetic relationships among dusky salamanders in the southern Blue Ridge and adjacent Piedmont Physiographic Provinces of Virginia and North Carolina revealed four distinct mitochondrial DNA clades that are also characterized by distinct allo enzyme markers.
