In the third panel filled points represent an analysis subtracting a single trap below a howler monkey sleeping tree.
Dispersed by large birds, howler and spider monkeys.
As predicted, small-island howlers consumed fewer resources and obtained a smaller fraction of their intake from rare tree species (those contributing < 1% of basal area).
One has to respect the integrity of a theorist who writes a book pointing out his own past howlers.
Activity patterns and feeding habits of translocated howler monkeys.
During five of these episodes, coatis just passed by a non-fruiting tree where the howler group was resting without interacting.
However, the question of how important predation is to the demography of mainland howlers remains open.
Recently, the physiological properties of howler monkey ganglion cells were analyzed through in vivo extracellular recordings.
