Patterns of cytonuclear discordance and divergence between subspecies of the scarlet macaw (Ara macao) in Central America.

The scarlet macaw, Ara macao, is a neotropical parrot that contains two described subspecies with broadly discrete geographical distributions. One subspecies, A. m.

Archaeogenomic evidence from the southwestern US points to a pre-Hispanic scarlet macaw breeding colony.

Hundreds of scarlet macaw () skeletons have been recovered from archaeological contexts in the southwestern United States and northwestern Mexico (SW/NW). The location of these skeletons, >1,000 km outside their Neotropical endemic range, has suggested a far-reaching pre-Hispanic acquisition network. Clear evidence for scarlet macaw breeding within this network is only known from the settlement of Paquimé in NW dating between 1250 and 1450 CE.

Overcoming Barriers.

Dr. Neal-Boylan's program of scholarship has always focused on nurse workforce issues. She recently published two books related to how nurses work.

Transformational leaders capitalizing on opportunities.

Many organizations have recently launched new goals, which provide strategic opportunities for nursing professional development specialists. Nursing professional development specialists are key to advancing nursing practice and are in unique positions to influence and leverage our expertise to promote the provision of safe quality care. We are transformational leaders.

A predicted ABC transporter, FtsEX, is needed for cell division in Escherichia coli.

FtsE and FtsX have homology to the ABC transporter superfamily of proteins and appear to be widely conserved among bacteria. Early work implicated FtsEX in cell division in Escherichia coli, but this was subsequently challenged, in part because the division defects in ftsEX mutants are often salt remedial. Strain RG60 has an ftsE::kan null mutation that is polar onto ftsX.
