2022 - Interactions of Alouatta palliata and Co-Existing Species at La Selva Biological Station - Poster Presentation
Title
2022 - Interactions of Alouatta palliata and Co-Existing Species at La Selva Biological Station - Poster Presentation
Description
Social grouping is rare among most mammals but is extremely routine within primates. With the increase in group living comes the increase in intraspecific foraging competition. However, niche divergence, or the differences in food selection and habitat use, may help mitigate this competition. Interactions between species are a major force in structuring ecological communities because they affect speciation, survival, and phenotypic divergence. In several studies of Alouatta seniculus, found in the Amazon, it was revealed they were absent from many sites compared to Ateles and Lagothrix species, suggesting that Ateles and Lagothrix shared common habitat use in certain sites found in the Amazon where Alouatta seniculus was absent. Because the number of Alouatta differs depending on their habitat location, understanding the coexistence of Alouatta and surrounding primates species is of the utmost importance because of how it affects the surrounding ecosystem. One of the coexisting primates at La Selva, Cebus capuchinus, tends to reside within the middle strata, using the upper canopies for travel, while Alouatta palliata tend to stay within the middle and upper canopies. Because of this slight overlap, I hypothesize both have interactions with one another. Whether those interactions are affiliative or aggressive will be recorded. I will record species, the proximity to the nearest neighbor, sex, and age. This study will be conducted at La Selva Research Station in May of 2022.

2022 - Mantled Howler Monkeys: Mate Guarding at La Selva Research Station (Aloutta, palliata)
Title
2022 - Mantled Howler Monkeys: Mate Guarding at La Selva Research Station (Aloutta, palliata)
Description
In the natural world, there are many reproductive strategies that are ways for organisms to increase their reproductive success. One reproductive strategy of primates is mate guarding, where they guard a reproductive female and won’t let her get near any other suitors. Mate guarding is often seen in multi-male and multi-female troops because the male wants to limit the female’s access to other males in the troop. Among monkeys of Central and South America, Alouatta palliata (mantled howler monkeys) has multi-male and multi-female troops. These troops are made up of non-kin members and male coalitions. There can be anywhere from 1 or more males and 9 or more females. Individuals of A. palliata are mostly black in color, with long, black guard hairs that give them the name “mantled”. A. palliata are polygynous and mate all year long. It is unclear if the rainforest structure at La Selva Research Station would lead A. palliata to mate guard or not. I predict that A. palliata at La Selva Research Station will mate guard females with no infants due to the rainforest structure being 43% re-growing secondary forest. I will investigate if mate guarding is one of the tactics used to deter other males from copulating with females. I will collect data by using instantaneous scan sampling at two-minute intervals. The data I will record will be the sex, age, whether the females have an infant, and proximity to the nearest neighbor. I will also record the nearest neighbor’s sex, and age. I will judge proximity by three categories: In contact (zero m apart), close will be more than zero and up to one m apart, and far will be greater than one m apart. This will be used to compare the proximity of males to females with no infants and the proximity of males to females with infants. Afterward, I will compare these results with those of A. palliata from other sites.
