Patterns of interspecific variation in labial microarchitecture among anthropoid primates and the evolution of the hominin lips

open access: yesThe Anatomical Record, EarlyView.
Comparative histological and semi‐automated image analysis of primate lips: Masson's trichrome‐stained sagittal sections were segmented to quantify the connective tissue, adipose, and muscular components, enabling interspecific comparisons of labial architecture.

The impact of urbanisation on social behaviour: a comprehensive review

open access: yesBiological Reviews, EarlyView.
ABSTRACT Urbanisation is a key driver of global environmental change and presents animals with novel stressors and challenges. It can fundamentally influence social behaviour and has the potential to reshape within‐ and between‐species social interactions. Given the role of social behaviour in reproductive fitness and survival, understanding how social

Morphological Characterization of Diaphragm in Common Squirrel Monkey (Saimiri sciureus)

open access: yesAnais da Academia Brasileira de Ciências, 2018
The wall of the diaphragm can be affected by congenital or acquired alterations which allow the passage of viscera between the abdominal and chest cavities, allowing the formation of a diaphragmatic hernia.

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

open access: yesBiological Reviews, EarlyView.
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 ...

Quantitative Analysis of Locus Coeruleus Neurons and Thalamic Noradrenergic Axons in a Progressive 1‐Methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine Monkey Model of Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease is mainly characterized by dopaminergic neurodegeneration in the substantia nigra pars compacta (SNc) and α‐synuclein accumulation. The locus coeruleus (LC) is also affected in Parkinson's disease and linked to some nonmotor symptoms, but the extent and timing of its degeneration remain unclear.

Acute Toxoplasmosis in Squirrel Monkeys.

open access: yesJournal of Veterinary Medical Science, 1997
Five cases of acute toxoplasmosis in caged squirrel monkeys (Saimiri sciureus) were reviewed. The early stages of systemic toxoplasmosis were present in all cases. In the liver, there were multiple foci of hepatocellular necrosis. The lung had diffuse interstitial pneumonia.
