As well as the common symptoms of post-polio syndrome, several associated symptoms can arise from the combination of fatigue, muscle weakness, and muscle and joint pain.
Squirrel monkeys are any of the species of monkeys that belong to the taxonomic genus Saimiri. The species and subspecies are distinguished mostly from fur coloring and shape, rather then behavior differences. They live in Central and South America and have similar habitats even though the range is very widespread.
Among common squirrel monkeys, S. sciureus, within-group feeding competition is intense because fruit is found in small, dense patches easily monopolized by one monkey. The incentive to protect this patch is high and the result is direct feeding competition between members of the group.
