Molecular phylogenies have yielded strong support for many parts of the amphibian Tree Life, but poor resolution deeper nodes, including relationships among families and orders. To clarify these relationships, we provide a phylogenomic perspective on by developing taxon-specific Anchored Hybrid Enrichment protocol targeting hundreds conserved exons which are effective across class. After obtaining data from 220 loci 286 species (representing 94% 44% genera), estimate phylogeny extant...
Significance Population structure and speciation are shaped by a combination of biotic abiotic factors. The tiger salamander complex has been considered key group in which life history variation led to rapid rate speciation, driven large part the evolution obligate paedomorphosis—a condition adults maintain an aquatic, larval phenotype. Using multilocus dataset, we present evidence gene flow between taxa with different strategies, suggesting that paedomorphosis is not strong driver complex....
Abstract Cytochrome B sequences and allozymes reveal complex patterns of molecular variation in dusky salamander ( Desmognathus ) populations eastern Tennessee. One group allozymically distinctive populations, which we refer to as the Sinking Creek form SCF ), combines morphological attributes fuscus with cytB characteristic carolinensis . This is abruptly replaced by D. just north Johnson City, TN no evidence either sympatry or gene exchange. To south, allozymic markers indicate a broad...
Body plan evolution often occurs through the differentiation of serially homologous body parts, particularly in arthropod plans. Recently, homeotic transformations resulting from experimental manipulation gene expression, along with comparative data on expression and function genes wing regulatory network, have provided a new perspective an old question insect evolution: how did evolve? We investigated metamorphic roles suite 10 wing- body-wall-related hemimetabolous insect, Oncopeltus...
Ecology and Evolution 2013; 3(8): pages 2547–2567 doi: 10.1002/ece3.636 Table 2 reports incorrect GAPDH allozyme frequencies for the Lemon Gap form at Locality 61, which is actually fixed GAPDH4, Sinking Creek 31, polymorphic GAPDH2 GAPDH3. We still assert that 36 may reflect gene exchange with LGF. A corrected version of appears below. The text end Results section bottom P. 15 should read as follows: “The populations localities 73 are or nearly same variants 16 presumptive loci, but exhibit...
A bstract The North American tiger salamander species complex, including its best-known species, the Mexican axolotl, has long been a source of biological fascination. complex exhibits wide range variation in developmental life history strategies, populations and individuals that undergo metamorphosis, those able to forego metamorphosis retain larval, aquatic lifestyle (i.e., paedomorphosis), do both. This assumed lead reproductive isolation speciation, but degree which it shaped population-...
