Abstract Studies of Upper Cretaceous deposits in North America have provided invaluable insights into the continental ecosystems of this time. Theropod (Saurischia, Dinosauria) pedal phalanges are commonplace in these deposits but can be difficult to identify at a finer taxonomic resolution.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Development of neuropeptide Y-ergic innervation of the small intestine in rats
Neuropeptide Y (NPY) acts as a neurotransmitter in the autonomic nervous system, including in the metasympathetic intramural ganglia of the intestine.

Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Changes in opioid signalisation during the ontogenesis.
Opioid receptors interact with opiate compounds, causing the inhibition of neuroexcitability. The activation of signaling pathway of opioid receptors plays crucial role in the treatment of chronic and cancer pain.

Dialectical inferences in the ontogenesis of social representations [PDF]
This article deals with a possible collaboration between two disciplines: developmental psychology and the theory of Social Representations (SR). The latter takes the study of the ontogenesis of social representations as a central issue, even though the ...

Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...
