CHEEK TOOTH MORPHOLOGY AND ANCIENT MITOCHONDRIAL DNA OF LATE PLEISTOCENE HORSES FROM THE WESTERN INTERIOR OF NORTH AMERICA: IMPLICATIONS FOR THE TAXONOMY OF NORTH AMERICAN LATE PLEISTOCENE EQUUS.

Horses were a dominant component of North American Pleistocene land mammal communities and their remains are well represented in the fossil record.Despite the abundant material available for study, there is still considerable disagreement over the number of species of Equus that inhabited the different regions of the continent and on their taxonomi

A female giant panda presented with a large, hard mass on the right cheek, which was investigated at the Dujiangyan Base of the China Conservation and Research Center for the Giant Panda with computed tomography (CT) scans and DANDELION biopsy of the oral mass, as well as venous blood sampling.Hematological tests revealed elevated levels of the tum

Despite the importance of Active Galactic Nuclei (AGN) Toners in galaxy evolution, the mechanisms that fuel AGN activity remain poorly understood.Theoretical models suggest that major mergers of galaxies contribute strongly to AGN fuelling, particularly at high AGN luminosities.The connection between mergers and AGN activity has therefore been wide
