The origin of platyrrhines: An evaluation of the Antarctic scenario and the floating island model
TL;DR: This paper evaluates whether protoplatyrrhines could have migrated to South America via Antarctica, and the floating island model is a plausible transoceanic mode of dispersal for land vertebrates like protoplateyrrhine, and whether a journey on a hypothetical floating island over the Paleogene Atlantic Ocean exceeds the survival limit.

Intratree vertical variation of fruit density and the nature of contest competition in frugivores
TL;DR: Red-tailed monkeys decreased their movements between successive fruits that they ate in the presence of blue monkeys compared to when they were feeding alone, perhaps to avoid disturbing dominants and attracting aggression or because they ingested more semi-ripe and green unripe fruits, i.e., more food of lower quality.

Vertical stratification of the nutritional value of fruit: macronutrients and condensed tannins.
TL;DR: Overall, upper‐crown feeding sites produced a higher density and quality of food than lower‐c Crown sites of the same tree, providing a clear nutritional explanation for why tree‐feeding frugivores compete for the highest feeding sites.

Contest competition for fruit and space among wild chimpanzees in relation to the vertical stratification of metabolizable energy
Alain Houle,Richard W. Wrangham +1 more
TL;DR: In a recent study, the authors found that covert contest competition over feeding sites gave dominant individuals an important advantage even in very large patches, where the amount of agonism can be puzzlingly low.

RESEARCH ARTICLE Vertical Stratification of the Nutritional Value of Fruit: Macronutrients and Condensed Tannins
Alain Houle,Richard W. Wrangham +1 more
- 01 Jan 2014
TL;DR: In this article, the authors measured how the nutritional value of a fruit is influenced by its ripeness and its height within the tree crown and found that the upper crown produced fruit densities 4.2 times higher, and a fruit crop 4.8 times larger, than the lower crown of the same tree.
