Abstract Many social animals acquire social behaviours during development, and social experience during development can be vital for acquiring necessary social behaviours in adulthood. We investigated the development of a distinctive tactile interaction behaviour in Bronze Cory catfish, in which adults interact with one another tactilely during foraging and during group responses to threats. We found that larvae respond to applied tactile stimulation with a flight response significantly less often as larvae matured. This habituation to tactile stimulation is consistent with developing appropriate adult social behaviour. We also found that social exposure affects the larval response to tactile interactions with conspecifics, and that isolation in early life leads to a greater likelihood of responding to tactile interactions with conspecifics with a flight response. This suggests that social exposure is important for developing social tactile interaction behaviour and underscores the particular importance of early experience in social development.

Social Exposure

AbstractVery young animals develop life skills as they mature, and for social animals this includes the acquisition of social abilities such as communication. Many animals exhibit changeable patterns of social behavior based on development, and social experience during the juvenile period can be vital for the development of necessary social behaviors in adulthood. We investigated the development of a distinctive tactile interaction behavior in Corydoras aeneus, the Bronze Cory catfish. Adults use this behavior to coordinate group activities during foraging and flight responses from predators, and the development of this behavior in larvae is of interest in investigating how communication and social behaviors develop as an individual matures, and which factors affect their development. We found that larvae respond to applied tactile stimulation with a flight response far less often as larvae matured, implying that larvae become less sensitive to tactile stimulation with age. Given that adults frequently interact with one another tactilely, this development is consistent with developing appropriate social behavior in adulthood. We also found that social exposure affects the development of the larval response to tactile interactions with conspecifics, and that isolation in the earliest larval stage leads to a greater likelihood of responding to a tactile interaction with a conspecific with a flight response. This suggests that social exposure is important for developing an appropriate response to tactile stimulation in social settings and underscores the particular importance of early life experiences in the development of sociality.

Early Rearing

Rats, conditioned to escape shock in a straight 6-ft. runway, were tested for the effects which early rearing and presence of different numbers of social animals had on fear-conditioned escape responses. The most significant findings were that: (a) for animals reared apart, the presence of another animal or animals had little or no effect upon fear-conditioned escape behavior; (b) for animals reared together, the presence of other animals resulted in fear reduction; (c) this fear-reducing influence of other animals seemed to have developed during the early life in a social situation; and (d) the group had to consist of at least three animals before its effects in fear situations were apparent.

This article employs the concepts of duplicity and posthegemony to analyse intimate and social interactions in Lucrecia Martel’s La niña santa [The Holy Girl] (2004) and Claudia Llosa’s Madeinusa (2005), focusing in particular on the personal and social development of each film’s female protagonist. By viewing the films through the psychoanalytic concepts of duplicity as defined by Harold Kelman and posthegemony as defined by Jon Beasley-Murray, we distinguish how each female protagonist strives toward posthegemonic status while adopting opposite approaches to duplicity. This is to say that Amalia entirely eschews duplicity while Madeinusa plays upon the liminalities of moral doubleness. In elaborating this argument, we will also demonstrate that both films represent a feminist critique of hegemony in which the emergent and emancipative subject liberates herself from the patriarchal apparatuses of the family, religion and community.

This review summarizes part of the author’s research in the area of supramolecular chemistry, beginning with his early life influences and early career efforts in molecular recognition, especially molecular tweezers. Although designed to complex DNA, these hosts proved more applicable to the field of host–guest chemistry. This early experience and interest in intercalation ultimately led to the current efforts to develop small molecule therapeutic agents for myotonic dystrophy using a rational design approach that heavily relies on principles of supramolecular chemistry. How this work was influenced by that of others in the field and the evolution of each area of research is highlighted with selected examples.

Social Animals

Microbes influence a wide range of host social behaviors and vice versa. So far, however, the mechanisms underpinning these complex interactions remain poorly understood. In social animals, where individuals share microbes and interact around foods, the gut microbiota may have considerable consequences on host social interactions by acting upon the nutritional behavior of individual animals. Here we illustrate how conceptual advances in nutritional ecology can help the study of these processes and allow the formulation of new empirically testable predictions. First, we review key evidence showing that gut microbes influence the nutrition of individual animals, through modifications of their nutritional state and feeding decisions. Next, we describe how these microbial influences and their social consequences can be studied by modelling populations of hosts and their gut microbiota into a single conceptual framework derived from nutritional geometry. Our approach raises new perspectives for the study of holobiont nutrition and will facilitate theoretical and experimental research on the role of the gut microbiota in the mechanisms and evolution of social behavior.

Social Behaviours

Data on rate and qualitative features of social interactions and on peer social involvement in play were obtained from repeated observation measures taken across 14 to 23 weeks on two children randomly selected from each of 6 kindergartens. Session-by-session variability was found to be a feature of the social interaction and social play data, and there was evidence that social behaviours may vary systematically across different kindergarten settings. A case is made for obtaining normative data in each setting of interest in order to identify atypical behaviour and to evaluate the social validity of intervention outcomes.

Abstract An animal's social behaviour both influences and changes in response to its parasites. Here we consider these bidirectional links between host social behaviours and parasite infection, both those that occur from ecological vs evolutionary processes. First, we review how social behaviours of individuals and groups influence ecological patterns of parasite transmission. We then discuss how parasite infection, in turn, can alter host social interactions by changing the behaviour of both infected and uninfected individuals. Together, these ecological feedbacks between social behaviour and parasite infection can result in important epidemiological consequences. Next, we consider the ways in which host social behaviours evolve in response to parasites, highlighting constraints that arise from the need for hosts to maintain benefits of sociality while minimizing fitness costs of parasites. Finally, we consider how host social behaviours shape the population genetic structure of parasites and the evolution of key parasite traits, such as virulence. Overall, these bidirectional relationships between host social behaviours and parasites are an important yet often underappreciated component of population-level disease dynamics and host–parasite coevolution.

Behavioural Development

A detailed analysis of the behavioural development of the red squirrel (Tamiasciurus hudsonicus) from birth to weaning is presented. For each behaviour pattern, the earliest and latest ages of emergence in a series of 14 young (from three litters) were registered and a mean was calculated. A review of the principal events of physical development is given first. The ontogeny of behaviour is then considered under five headings: locomotion, alertness and exploration, feeding, comfort, and social interactions. In the discussion, a general analysis of the development of behaviour with regard to the different periods of ontogeny (neonatal period, transition period, and socialization period) and the two leading events of the early life of the red squirrel (emergence from the nest and weaning) is given. It appears that the young are equipped with a minimum of behaviour patterns during the period of nest confinement and that close to emergence, a series of new behaviours come into effect with the exception of locomotion, which evolves gradually and regularly during ontogeny.

The social world is filled with different types of interactions, and social experience interacts with stress on several different levels. Activation of the neuroendocrine axis that regulates the response to stress can have consequences for innumerable behavioural responses, including social decision-making and aspects of sociality, such as gregariousness and aggression. This is especially true for stress experienced during early life, when physiological systems are developing and highly sensitive to perturbation. Stress at this time can have persistent effects on social behaviours into adulthood. One important question remaining is to what extent these effects are adaptive. This paper initially reviews the current literature investigating the complex relationships between the hypothalamic-pituitary-adrenal (HPA) axis and other neuroendocrine systems and several aspects of social behaviour in vertebrates. In addition, the review explores the evidence surrounding the potential for ‘social programming’ via differential development and activation of the HPA axis, providing an insight into the potential for positive effects on fitness following early life stress. Finally, the paper provides a framework from which novel investigations could work to fully understand the adaptive significance of early life effects on social behaviours. This article is part of the themed issue ‘Physiological determinants of social behaviour in animals'.
