“…Furthermore, low levels of aggression are known to lead to improvements in vigilance, predator detection and survival ( Jakobsson 1987;Brick 1998). For example, in a study of territorial willow warblers the responses to the playback of an intruder's song and the presentation of a model intruder (stuffed pygmy owl) were measured for pairs of males involved in escalated fighting and low-intensity fighting.…”

“…Familiar dyads exhibit lower aggression levels (Beaugrand & Zayan 1985;Johnsson 1997;O'Connor et al 2000) and initiators of conflicts are more likely to win against familiar than against unfamiliar competitors (Hö jesjö et al 1998). Importantly, because intense fighting may lead to an increased risk of being preyed upon ( Jakobsson 1987;Brick 1998), the decision to associate preferentially with familiar conspecifics may confer anti-predator advantages on individuals. Surprisingly, however, the advantages of choosing familiar partners remain unclear (Chivers et al 1995;Metcalfe & Thomson 1995;Hö jesjö et al 1998;Wisenden & Smith 1998;Utne-Palm & Hart 2000).…”

The ability of an animal to perform a task successfully is limited by the amount of attention being simultaneously focused on other activities. One way in which individuals might reduce the cost of divided attention is by preferentially focusing on the most beneficial tasks. In territorial animals where aggression is lower among familiar individuals, the decision to associate preferentially with familiar conspecifics may therefore confer advantages by allowing attention to be switched from aggression to predator vigilance and feeding. Wild juvenile brown trout were used to test the prediction that familiar fishes respond more quickly than unfamiliar fishes to a simulated predator attack. Our results confirm this prediction by demonstrating that familiar trout respond 14% faster than unfamiliar individuals to a predator attack. The results also show that familiar fishes consume a greater number of food items, foraging at more than twice the rate of unfamiliar conspecifics. To the best of our knowledge, these results provide the first evidence that familiarity-biased association confers advantages through the immediate fitness benefits afforded by faster predator-evasion responses and the long-term benefits provided by increased feeding opportunities.

“…In escalated encounters by territory resident Chaetodon, the lateral display could be followed by the dorsal-anal fin extension behavior or the tail slap behavior at a distance of one to two body lengths from the receiver. The use of relatively weak tail slaps or 'beating' during lateral displays is common in fishes (Chizar, 1978), and is described for some cichlids as stationary swimming with strong undulations (Barlow, 1967), and a low-intensity aggressive behavior (Enquist and Lemar, 1983;Brick, 1998). By contrast, the tail slap behavior by C. multicinctus is brief but probably energetically expensive.…”

SUMMARY Butterflyfishes are conspicuous members of coral reefs and well known for their visual displays during social interactions. Members of the genus Chaetodon have a unique peripheral arrangement of the anterior swim bladder that connects with the lateral line (the laterophysic connection) and in many species projects towards the inner ear. This morphology has lead to the proposal that the laterophysic connection and swim bladder system may be a specialized structure for the detection of sound. However, the relevant stimuli, receiver mechanisms and functions for these putative hearing structures were unknown because butterflyfishes were previously not recognized to produce sounds during natural behavior. We performed field experiments to test the hypothesis that Chaetodon produces sounds in natural social contexts. Acoustic and motor behaviors of the monogamous multiband butterflyfish, C. multicinctus, were evoked and recorded by placement of bottled fish into feeding territories of conspecific pairs. We demonstrate that territory defense includes the production of agonistic sounds and hydrodynamic stimuli that are associated with tail slap, jump, pelvic fin flick and dorsal-anal fin erection behaviors. In addition, grunt pulse trains were produced by bottled intruders and are tentatively interpreted to function as an alert call among pair mates. Acoustic behaviors include low frequency hydrodynamic pulses <100 Hz, sounds with peak energy from 100 Hz to 500 Hz,and a broadband high frequency click (peak frequency=3.6 kHz), which is produced only during the tail slap behavior. These results provide a biological framework for future studies to interpret the proximate function of the acoustico-lateralis sensory system, the evolution of the laterophysic mechanism and their relevance to butterflyfish social behavior.

“…Experiences could also influence the individual's perception of its current environmental situation. For example, a fish that recently encountered a predator in a particular location may be less likely to engage in intense aggressive behaviour (Brick 1998(Brick , 1999 and spend more time scanning for potential predators than another fish at the same place that has never encountered a predator there. Early ecological models of behavioural variation assumed that organisms had perfect information about the benefits and costs of behaviour in the situation being investigated (e.g.…”

As the introductory chapter to the first edition of this book (Brown et al. 2006) noted, fish behaviour has long been viewed as stereotyped and not strongly influenced by context or experience. The recognition that experience and learning can influence fish behaviour coupled with observations of considerable variation in behaviour within and between individuals has led to an increasing awareness of the complexity of fish behaviour. Behavioural ecologists are interested in understanding the causes and effects of behavioural variation within individuals (e.g. over time), among individuals of a population and among populations. These causes and effects are related to the benefits and costs of the behaviour that influence the evolutionary success (fitness) of the individual.Over 40 years ago Tinbergen (1963) noted that behavioural variation could be examined from multiple perspectives. This variation could result, for example, from differences within and among individuals in genetics, age, size, sex, developmental history and morphological and physiological constraints. The variation could also be related to environmental situations encountered by an individual in the present or past and could result from the individual's past experiences. Behavioural variation presumably results from how each of these factors influences the benefits and costs of behaviour at a particular time and place. However, a more comprehensive understanding of behavioural variation will emerge only by integrating these different perspectives.Experiences could influence variables such as size, developmental history and physiological state that are predicted or observed to lead to behavioural differences. Experiences could also influence the individual's perception of its current environmental situation. For example, a fish that recently encountered a predator in a particular location may be less likely to engage in intense aggressive behaviour (Brick 1998(Brick , 1999 and spend more time scanning for potential predators than another fish at the same place that has never encountered a predator there.
