A DNA Sequence–Based Approach To the Identification of Shark and Ray Species and Its Implications for Global Elasmobranch Diversity and Parasitology
A comprehensive survey of DNA sequences derived from the mitochondrial NADH2 gene was conducted for elasmobranchs collected from around the world, suggesting 79 potentially new taxa that are genetically distinct from their closest relatives in other regions.
Elasmobranch Phylogeny: A Mitochondrial Estimate Based on 595 Species
Interest in elasmobranch biodiversity and taxonomy has grown in recent years, catalyzed primarily by four influences: (1) the large number of new species that have been described over the past 30
Rates of mitochondrial DNA evolution in sharks are slow compared with mammals
Examination of mtDNA sequence variation for 13 species of sharks from two orders that are well represented in the fossil record to test the constancy hypothesis finds differences in mtDNA substitution rates among taxa indicate that it is inappropriate to use a calibration for one group to estimate divergence times or demographic parameters for another group.
Molecular phylogenetics and evolution of turtles.
Towards complete and error-free genome assemblies of all vertebrate species
The Vertebrate Genomes Project is embarked on, an effort to generate high-quality, complete reference genomes for all ~70,000 extant vertebrate species and help enable a new era of discovery across the life sciences.
Species delineation and global population structure of Critically Endangered sawfishes (Pristidae)
It is shown that populations of sawfish exhibit significant geographic structuring across their respective ranges, meaning that regional-level conservation will be required, and the NADH-2 gene may serve as a marker for the identification of rostra and fins involved in illegal trade.
Capturing protein-coding genes across highly divergent species.
Modifications are introduced that extend the reach of DNA hybridization capture to allow efficient capture of highly divergent homologous target sequences using a single set of baits, having important implications for comparative biology.
The Effect of Taxon Sampling on Estimating Rate Heterogeneity Parameters of Maximum-Likelihood Models
This work illustrates that estimates of rate heterogeneity parameters are highly sensitive to taxon sampling when the data are best explained by a mixeddistribution model of among-site rate variation (invariable sites plus gamma distribution [I1G]; and attempts to differentiate two possible causes of this sensitivity.
Phylogenetic Relationships among the Major Lineages of Modern Elasmobranchs
A phylogenetic tree based on DNA sequence comparisons for the C H A P T E R 1 is established to establish an even, balanced and representative coverage of the evolutionary trajectory of the vertebrate evolutionary tree.
