Ecomorphology of the giant short-faced bears Agriotherium and Arctodus
The hypothesis that giant short-faced bears of the genera Agriotherium and Arctodus were primarily carnivorous and preyed on large terrestrial mammals is examined. It is argued that the shape and
Population Aggregation Analysis of Three Caviar-Producing Species of Sturgeons and Implications for the Species Identification of Black Caviar
Recent declines in population size of the three commercial species, combined with an increase in the demand for caviar on the interna- tional market, could have caused the observed mislabeling.
Ecomorphology of the giant bear-dogs Amphicyon and Ischyrocyon
Relative grinding area (RGA) of lower molars and wear pattern on upper molars suggest that bear-dogs were carnivorous, and previously proposed models of diet and hunting behaviour of these extinct carnivorans are tested.
A biomechanical constraint on body mass in terrestrial mammalian predators
The results support the existence of the proposed biomechanical constraint, although paleoecological datasuggest that some lineages of terrestrial mammalian predators failed to reach the limits,imposed by this constraint, because of the small size of available prey.
Limb bone stresses during fast locomotion in the African lion and its bovid prey
The comparison suggests that both the humerus and the tibia of a running lion have higher safety factors than those of its bovid prey running at the same speed.
Microscopic Electron-Phonon Theory of Ferroelectricity in Perovskite Oxides
The energy of the electronic subsystem of oxides (BaTiO 3 , etc.) renormalized by dynamical electron-phonon hybridization of valence 2p oxygen states and conduction 3d Ti states (or Nb, etc. states)

ABSTRACT Previously proposed hypothesis that known terrestrial and flightless members of the pennaraptoran clade Oviraptorosauria (Dinosauria: Theropoda) evolved from scansorial and volant ancestors
