Optimal Foraging

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Ecological Niches

Ecological Niches

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Symbiosis

Symbiosis

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Cognitive Ecology
Network Science

Background:

Collectives can outperform individuals in information processing.
Fission-fusion dynamics involve dynamic group structures and information sharing.
Complementary knowledge sharing is crucial for navigating heterogeneous environments.

Purpose of the Study:

To investigate how spider monkeys share foraging information in fission-fusion dynamics.
To analyze the structure of social interactions and information overlap within spider monkey groups.
To model collective information processing in dynamic environments using network analysis.

Main Methods:

Analysis of partial overlaps in individual spider monkey core ranges to represent seasonal knowledge.
Identification of sets of individuals with complementary knowledge overlaps.
Utilizing simplicial complexes to model higher-order interactions and information sharing patterns.

Main Results:

Complementary foraging knowledge was identified among sets of individuals.
Simplicial complex structures revealed holes in various dimensions, indicating information complementarity.
The study demonstrated a balance between redundant and unique knowledge within the group.

Conclusions:

Complex spatial networks in fission-fusion dynamics facilitate adaptive collective foraging information processing.
Spider monkey social structures enable efficient navigation of dynamic and heterogeneous environments.
Distributed information processing through social networks is a key adaptation for survival.
