We present several arguments for the preeminence of social interactions in determining and giving shape to societies. In our view, a society can emerge from social interaction and relationship patterns without the need for establishing an a priori limit on who actually belongs to it. Markers of group identity are one element among many that allow s...

In May and June 2024, a die-off of Mexican mantled howler monkeys (Alouatta palliata mexicana) occurred in southern Mexico. This commentary documents the event, attributing it to extreme heatwaves, drought, wildfires, and habitat impoverishment. Despite their reported resilience to habitat disturbances, mantled howler monkey mortality rate in some...

Maternal kinship can structure social relationships in mammals, as demonstrated in species characterized by female philopatry. In these species, females tend to be closely related and interact more often with maternal relatives. However, there is limited evidence indicating a role of maternal kinship in species characterized by male philopatry. To...

A long developmental period in animals is often needed to learn skills for adult reproduction and survival, including feeding behaviour. The nocturnal Javan slow loris, Nycticebus javanicus, is unusual in that it consumes a specialized diet of difficult to extract resources, as well as disperses up to a year after sexual maturity. Here, we examined...

Deforestation is widely recognised as an agent of human disturbance that causes widespread destruction of species habitats and can result in animals occupying forest patches with limited food resources. When animals are forced to change habitats, they must also adjust their diet, activity budgets and social behaviour in response to facing new ecolo...

The chapter is about affiliative behaviours, factors that influence affiliative behaviours, and benefits of affiliative behaviours

Abstract: Habitat loss and fragmentation are major threats to the Mexican mantled howler monkey (Alouatta palliata mexicana) which have drastically reduced the size of its natural populations. This reduction negatively affects its genetic diversity. However, information regarding genetic aspects of this subspecies in fragmented landscapes is limite...

Habitat loss and fragmentation are major threats to Mexican mantled monkey (Alouatta palliata mexicana), which have reduced drastically the size of its natural populations. This reduction causes a negative impact on its genetic diversity, which in turns threatens the viability of its remnant populations. In this study, genetic diversity is determin...

En este trabajo se investigó el efecto de una variable ecológica (disponibilidad de alimento) en la conducta social de infantes y juveniles de la especie Alouatta palliata mexicana.
