Studies on the regulation of plasma cholesterol levels in squirrel monkeys of two genotypes
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

Worldwide, transportation agencies have been involved in road mitigation efforts to reduce road mortality and promote connectivity of endangered species. Baseline data on how mammals respond to highway construction, however, are rarely collected in road mitigation and monitoring studies, including in the USA.

Urban expansion is a major driver of habitat fragmentation, shrinking wildlife habitat, and restricting wildlife movements and activity patterns. In this novel environment, species must adapt to the new composition of wildlife communities. For example, red squirrels Sciurus vulgaris are commonly found in urban environments, while their potential ...

Space Use Preferences and Species Proximity in a Mixed-Species Zoo Monkey Exhibit
Many zoos display animals in mixed-species exhibits where multiple different species share the same space and potentially interact. This study analyzes a mixed-species exhibit with three New World monkey species (white-faced saki, black-capped squirrel ...

Cholesterol metabolism in rhesus monkey, squirrel monkey, and baboon
The metabolism of cholesterol wastudied in baboons, rhesus monkeys, and squirrel monkeys while they were being fed either a low fat, low cholesterol (basal) diet or the basal diet supplemented with saturated fat and cholesterol (atherogenic diet).

Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

ABSTRACT The emergence of anthelminthic resistance is a well‐documented phenomenon in livestock and companion animals. Given the scarcity of new antiparasitic drugs, the implementation of effective, holistic anthelminthic control strategies is critical to preserving the efficacy of existing treatments.

Demographic buffering in natural populations: A multi‐level perspective
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Abstract Background and Purpose Opioid use disorder, particularly involving fentanyl, poses major challenges due to high relapse rates and limited effectiveness of pharmacotherapies. The kynurenine pathway has emerged as a target for addiction treatment through its modulation of glutamatergic and dopaminergic neurotransmission.

The concentration of lysophosphatidylcholine (monoacyl sn-glycerol 3-phosphorylcholine) in intima plus inner media of atherosclerotic aorta from squirrel monkeys was nearly eight times that in comparable control tissue. Plasma levels of the same compound
