Does tooth wear influence ageing? A comparative study across large herbivores
256.69 KB 0 downloads
Abstract: We test whether the intensity of tooth wear influences the strength of actuarial senescence across species of large herbivores. We collected from the literature data on tooth wear in the wild (measured...

The Interrelationships of Higher Ruminant Families with Special Emphasis on the Members of the Cervoidea
12.77 MB 0 downloads
Abstract: We analyze the interrelationships of the higher (Pecoran) ruminants, and suggest possible relationships between these families and the various genera of the polyphyletic assemblage "Gelocidae." We also...

K-Casein Gene Phylogeny of Higher Ruminants (Pecora, Artiodactyla)
566.97 KB 0 downloads
Abstract: To asses phylogenetic relationships among the higher ruminants (infraorder Percora, order Artiodactyla), we analyzed K-casein DNA sequences, including 434 nucleotides of the fourth exon. The higher ruminant...

Old world ruminant morphophysiology, life history, and fossil record: exploring key innovations of a diversification sequence
646.07 KB 0 downloads
Abstract: The omasum of pecoran ruminants (which is absent in tragulids) and shorter gestation periods in non-giraffid crown pecorans (as opposed to giraffids) could represent cases of key innovations that caused...
