Molecular phylogeny of a cosmopolitan group of woodpeckers (genus Picoides) gased on COI and cyt b mitochondrial gene sequences.

Picoides is the largest genus of woodpeckers and member species are found on most major land masses. Current systematic arrangement of this group, based on morphological, behavioral, and plumage characters, suggests that New World species evolved from a single invasion by a Eurasian common ancestor and that all New World species form a monophyletic group. No clear link has ever been established between the relationships of Old World and New World species other than to infer that the most primitive species is Eurasian. This study employs DNA sequences for two protein-coding mitochondrial genes, cytochrome oxidase I and cytochrome b, to reconstruct phylogenetic relationships among all New World species and several Eurasian representatives of the genus Picoides. A well-resolved mitochondrial gene tree is in direct conflict with proposed species relationships based on nongenetic characters; monophyly among New World species is rejected, the evolution of New World species likely resulted from as many as three independent Eurasian invasions, and Picoides is paraphyletic with two other woodpecker genera, Veniliornis and Dendropicos. These results strongly suggest that this large, cosmopolitan genus is in need of systematic revision in order to reflect evolutionary history.

A test of a mitochondrial gene-based phylogeny of woodpeckers (genus Picoides) using an independent nuclear gene, beta-fibrinogen intron 7.

A conservative estimate of the species tree for the woodpecker genus Picoides based on two mitochondrial protein-coding genes is tested using sequences of an independently evolving nuclear intron, beta-fibrinogen intron 7. The mitochondrial gene-based topology and the intron-based topology are concordant, and a partition-homogeneity statistical test did not detect phylogenetic heterogeneity. The intron evolves more slowly than the mitochondrial sequences and tends not to resolve relationships among recently evolved species. However, the intron is superior over mitochondrial genes in resolving older bifurcations in the phylogeny. The two data sets were combined resulting in a robust estimate of the Picoides species tree in which most every node is statistically supported by bootstrap proportions. The Picoides species tree clearly shows that many morphological and behavioral characters used to lump species into this single genus have evolved by convergent evolution. Picoides is considered the largest genus of woodpeckers, but the molecular-based species tree suggests that Picoides is actually a conglomerate of several smaller groups.

Dental digital radiography.

Digital images offer tremendous advantages to dentistry in terms of the potential for lower exposure to patients, absence of darkroom or processing problems, convenience of image enhancement techniques and capacity for remote teledentistry. Digital systems are now able to acquire all types of images including panoramic and cephalometric. As technology continues to improve they may ultimately replace film as the medium of choice for dental imaging.
