Communication is key: Mother-offspring signaling can affect behavioral responses and offspring survival in feral horses (Equus caballus).

Abstract: Acoustic signaling plays an important role in mother-offspring recognition and subsequent bond-formation. It remains unclear, however, if mothers and offspring use acoustic signaling in the same ways and for the same reasons throughout the juvenile stage, particularly after mutual recognition has been adequately established. Moreover, despite its critical role in mother-offspring bond formation, research explicitly linking mother-infant communication strategies to offspring survival are lacking. We examined the communicative patterns of mothers and offspring in the feral horse (Equus caballus) to better understand 1) the nature of mother-offspring communication throughout the first year of development; 2) the function(s) of mother- vs. offspring-initiated communication and; 3) the importance of mare and foal communication to offspring survival. We found that 1) mares and foals differ in when and how they initiate communication; 2) the outcomes of mare- vs. foal-initiated communication events consistently differ; and 3) the communicative patterns between mares and their foals can be important for offspring survival to one year of age. Moreover, given the importance of maternal activity to offspring behavior and subsequent survival, we submit that our data are uniquely positioned to address the long-debated question: do the behaviors exhibited during the juvenile stage (by both mothers and their young) confer delayed or immediate benefits to offspring? In summary, we aimed to better understand 1) the dynamics of mother-offspring communication, 2) whether mother-offspring communicative patterns were important to offspring survival, and 3) the implications of our research regarding the function of the mammalian juvenile stage. Our results demonstrate that we have achieved those aims.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research explores the importance of acoustic communication between mother horses and their offspring for survival and behavioral responses, specifically during the first year of development. It aims to understand the different communication patterns and their implications for the offspring’s survival and the broader significance for juvenile mammalian behavior.

Understanding Mother-Offspring Communication

  • The researchers investigated the communicative patterns of mother-offspring in feral horses.
  • Specifically, they focused on the first year of development, which is an important period for forming bonds and recognizing each other.
  • The query is if this acoustic signaling stays the same after this mutual recognition, since it’s unclear whether the patterns remain constant or change over time.

Communication Initiation and Consequences

  • The research further delves into who initiates communication—mare or foal—and the outcomes of their communication tactics.
  • The results show that mother horses (mares) and their young (foals) differ in when and how they initiate communication.
  • It also shows disparities between mare- and foal-initiated communication events: they consistently have different outcomes.

Linking Communication to Offspring Survival

  • A significant aspect of this research is linking mother-infant communication strategies with offspring survival, a domain that hasn’t been considerably explored before.
  • The researchers found that the communication patterns between mares and their foals can be crucial for the survival of the young up to one year of age.

Implications for Juvenile Behaviour

  • The study argues that their data can contribute to the long-standing question of whether behaviors exhibited during the juvenile stage by mothers and their young have immediate or delayed benefits to the offspring.
  • It does this by analyzing the effect of the mother’s activity on offspring behavior and, consequently, their survival.
