SEMEN COLLECTION IN THE SQUIRREL MONKEY [PDF]

open access: yesReproduction, 1967
The first successful attempt to collect semen from monkeys was reported by Mastroianni & Manson ( 1963) using adult macaques. A monophasic, alternating current was applied through two surface electrodes, one around the base of the penis, the other against the ventral aspect of the glans near the frenulum.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
