      Rideout, Bruce; Njaa, Bradley L. (John Wiley & Sons, 2012)
      Kirkbride's Diagnosis of Abortion and Neonatal Loss in Animals, Fourth Edition is a concise resource for determining the causes of abortion and neonatal loss in cattle, small ruminants, pigs, horses, dogs, cats, and exotic mammals…. Covers cattle, sheep, goats, pigs, horses, dogs, cats, and non-domestic mammals Details the characteristics of many abortifacient causes and associated lesions….
    • Molecular phylogeny and evolution of the Perissodactyla

      Steiner, Cynthia C.; Ryder, Oliver A. (2011)
      The evolution of perissodactyls (rhinoceroses, tapirs, and horses) has been well studied primarily because of their extensive fossil record. Nevertheless, controversy persists regarding relationships of some of the extant taxa, reflecting inconsistencies between molecular and morphological studies. Here we examine the phylogenetic relationships of 16 living perissodactyl species by concatenating two mitochondrial and nine nuclear genes, and we estimate their divergence times using a relaxed Bayesian molecular clock approach....
    • Molecular phylogeny of extant equids and effects of ancestral polymorphism in resolving species-level phylogenies

      Steiner, Cynthia C.; Mitelberg, A.; Tursi, R.; Ryder, Oliver A. (2012)
      …Here we studied the phylogenetic relationships of all extant species of Equidae by analyzing 22 partial mitochondrial and nuclear genes using maximum likelihood and Bayesian inferences that account for heterogeneous gene histories. We also examined genetic signatures of lineage sorting and/or genetic introgression in zebras by evaluating patterns of intraspecific genetic variation….
