Eksempler på howler

• Isolation and the absence of contact with other howlers may protect against parasites and disease, thereby reducing mortality.

• In contrast, predators of invertebrates, rodents and generalist herbivores (leaf-cutter ants, howler monkeys, common iguanas) are present at greatly elevated densities.

• While following the howler monkey group, all interspecific encounters between howler monkeys and coatis were recorded.

• Factors influencing leaf choices by howler monkeys: a test for some hypotheses of food selection by generalist herbivores.

• Factors influencing the leaf choice by howler monkeys: test of some hypotheses of food selection by generalist herbivores.

• These results are consistent with the earlier predictions suggesting that howler monkeys are routinely trichromatic.

• Finally, the establishment of a sound management programme is crucial for the future well-being of howlers on the island.

• Recently, the physiological properties of howler monkey ganglion cells were analyzed through in vivo extracellular recordings.

• However, the question of how important predation is to the demography of mainland howlers remains open.

• During five of these episodes, coatis just passed by a non-fruiting tree where the howler group was resting without interacting.

• Activity patterns and feeding habits of translocated howler monkeys.

• One has to respect the integrity of a theorist who writes a book pointing out his own past howlers.

• 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).

• Dispersed by large birds, howler and spider monkeys.

• In the third panel filled points represent an analysis subtracting a single trap below a howler monkey sleeping tree.
