Maintaining social cohesion through coordinating traveling time and direction is a primary benefit of group living in mammals. During a 15-month study, we investigated socioecological factors underlying leadership of collective group movements in three multimale–multifemale groups of black howler monkeys (Alouatta pigra) at Palenque National Park (PNP), Mexico. A total of 691 independent group movements across a variety of contexts were collected. Leadership of group movements was partially… 

Ethological studies of native Mexican mammals: A review

The number of ethological studies based on Mexican mammals have increased in recent years compared to those from other Latin American countries.  This study conducts an analytical review of the

Leadership of old females in collective departures in wild bonobos (Pan paniscus) at Wamba

It is found that the frequency of initiation was associated with the individual’s age, affiliative relationships, and male dominance rank, and the three oldest females initiated departures more frequently than expected, suggesting that these individuals were habitual initiators and took an important role to preserve cohesiveness.



Individual and social determinants of spontaneous group movements in cattle and sheep.

It is concluded that preferential bonds and individual traits related to social dependence were more influential in spontaneous group movements at pasture than were emotional traits and dominance status.

Coordination of Group Movements in Wild Red-fronted Lemurs (Eulemur rufifrons): Processes and Influence of Ecological and Reproductive Seasonality

Study of red-fronted lemurs in Kirindy Forest, Madagascar, between 2008 and 2010 provides new insights into seasonal variability of coordination processes and the role of social dominance in lemur group movements, thereby contributing to a comparative perspective from a primate radiation that evolved group living independently of anthropoids.

Reaching a Consensus: Terminology and Concepts Used in Coordination and Decision-Making Research

It is recommended that future studies on coordination and decision-making in animal groups do not use the terms “combined decision” and “democratic/despotic decision- making” to avoid ambiguity as well as anthropocentric connotations.

Leadership in mixed-sex groups of muskoxen during the snow-free season

Adult females emerged as leaders in all 3 contexts, and other group members were more likely to follow adult females than adult males during initiations of activity, and half of successful initiations by adult males included aggressive behavior toward females.

Where Next? Group Coordination and Collective Decision Making by Primates

Primate groups need to remain coordinated in their activities and collectively decide when and where to travel if they are to accrue the benefits and minimize the costs of sociality. The achievement

Mechanisms of Cohesion in Black Howler Monkeys

All diurnal primates live in social groups but with a great range of variation in the types of groups they form. Primate societies vary in group size, composition, dispersal patterns, levels of

Coordination of Group Movements in Non-human Primates

This chapter summarises the current understanding of variation in spacing patterns, types of leadership, and decision-making processes in group movements in non-human primates and proposes an operational definition that has already been applied successfully in studies of small free-ranging groups.
