The impact of urbanisation on social behaviour: a comprehensive review
Biological 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

COMPARISON OF EMOTIONAL RESPONSES IN MONKEYS WITH RHINAL CORTEX OR AMYGDALA LESIONS [PDF]
, 2002 Four emotionally arousing stimuli were used to probe the behavior of monkeys with bilateral ablations of the entorhinal and perirhinal cortex. The animals’ behavioral changes were then contrasted with those observed earlier (Meunier et al., 1999) in ...

Movement 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.

Studies on the regulation of plasma cholesterol levels in squirrel monkeys of two genotypes
Journal of Lipid Research, 1972 Certain individual squirrel monkeys (“hyporesponders”) are able to remain normocholesterolemic when fed diets containing cholesterol (0.5 mg/kcal). Other squirrel monkeys (“hyperresponders”) when fed the same diet become hypercholesterolemic. The purpose

Acute Toxoplasmosis in Squirrel Monkeys.
Journal 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.
