“…We also found that the presence of highly connected individuals (or "hubs") in a random, scale-free network is important for collective learning. This is coincident with the results of an empirical study of spider monkeys [42] that found that more central individuals lead collective movements and are followed to available feeding trees that they know about more frequently than non-central individuals.…”

“…Similarly, in foraging groups, six or seven neighbours may be a good compromise between the benefit of gathering valuable information from others and limited sensory and memory capacities. In an empirical study aimed specifically at uncovering the rules by which spider monkeys share information about feeding trees [42], individuals that know about available feeding trees share this information with an average of 4.25 (±3.75 S.D.) individuals over several detailed observations at feeding trees.…”

“…Studies over the past decades have substantially advanced our understanding of the mechanisms by which social structure—the content, quality and patterning of social connections among individuals in a population (Hinde, 1976)—arises, and how social structure shapes social processes (Sueur, Romano, Sosa, & Puga‐Gonzalez, 2019). For example, (dis)assortativity around individual traits and states—for example, genetic relatedness, sex, age, dominance, promiscuity, behavioural repertoire—can influence social interactions (Croft et al., 2009; Farine, Montiglio, & Spiegel, 2015; McDonald, Spurgin, Fairfield, Richardson, & Pizzari, 2019; Pike, Samanta, Lindstrom, & Royle, 2008); early‐life conditions affect adult social decisions (Farine, Spencer, & Boogert, 2015); and the social environment can affect collective decision‐making (Palacios‐Romo, Castellanos, & Ramos‐Fernandez, 2019; Strandburg‐Peshkin, Farine, Crofoot, & Couzin, 2017) or dispersal and recruitment (Armansin et al., 2020; Ilany, Barocas, Koren, Kam, & Geffen, 2013; McDonald, 2007). Sometimes, who individuals are connected to, or the overall structure of populations, can also simply arise from limitations in where individuals can move and, therefore, who they can encounter (e.g.…”

“…The circuit of individual strategies that we infer here is, at least in part, a reflection of information sharing about available patches. Following another individual when ignorant is a simple mechanism of information sharing (Palacios-Romo et al, 2019), that could be reflected in the dyadic weights we have measured. This would lead to a fully connected circuit with information about food sources promoting a flexible grouping pattern that matches heterogeneity in the environment.…”

“…Fission-fusion social dynamics, in which individuals fission and fuse into subgroups of varying size, is a collective pattern arising from individual decisions (Sueur et al, 2011 ; Ramos-Fernández et al, 2018 ). These dynamics are thought to be adaptive, as they allow individuals to forage more efficiently in heterogeneous environments, share information about the location of resources, and adjust the size of their subgroups to resource availability (Aureli et al, 2008 ; Sueur et al, 2011 ; Palacios-Romo et al, 2019 ). The individual, strategic decisions to leave or join subgroups, how these decisions influence subgroup size distributions, and whether these are a good fit or even predicted by environmental states, are open questions.…”
