Title Cooperation and the Prisoner's Dilemma: towards testable models of mutualism versus reciprocity Type Journal Article
Year 1997 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 54 Issue 3 Pages 551-557
Keywords
Abstract For the purpose of distinguishing between mutualism and reciprocity in nature, recent work on the evolution of cooperation has both oversimplifed and undersimplified the distinction between these two categories of cooperation. This article addresses the resulting issues of model testability, clarifies the role of time and argues that the category of `pseudo-reciprocity' is an unnecessary complication.

Title Female mate-choice copying in guppies,Poecilia reticulata: a re-evaluation Type Journal Article
Year 1997 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 54 Issue 3 Pages 579-586
Keywords
Abstract It has been argued that intraspecific mate-choice copying can be adaptive under certain conditions. Dugatkin's (1992,Am. Nat.139, 1384-1389) work with guppies,Poecilia reticulataremains the most influential experimental demonstration of this phenomenon. We replicated Dugatkin's work using several choice criteria to ensure that our results were not dependent upon any single method of judging mate choice. We also tested our findings against two null hypotheses of differing stringency. Irrespective of the choice criteria or null hypothesis used, we did not observe any relationship between female mate choice and copying. We conclude that further experimental evidence of female mate-choice copying is required before the existence of this behaviour can be affirmed.

Title On the spurious occurrence of Tit for Tat in pairs of predator-approaching fish Type Journal Article
Year 1997 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 53 Issue 1 Pages 113-131
Keywords
Abstract An experimental analysis of the movements of predator-approaching fish is presented. The experiments evaluated two competing hypotheses. (1) Predator-approaching fish play the game-theoretical strategy Tit for Tat. Alternatively, (2) the movements of predator-approaching fish superficially resemble Tit for Tat, because fish independently orient to a predator and simultaneously attempt to stay close together. Experimental subjects were mosquito fish,Gambusia affinisapproaching a green sunfish,Lepomis cyanellusTwo experiments were performed. Experiment 1 replicated results of Milinski (1987) and Dugatkin (1991), showing thatGambusiacome closer to a visible predator when a mirror is oriented parallel to their direction of travel. Experiment 2 attempted to separate the effects of common orientation and social cohesion in accounting for the frequency of Tit-for-Tat-like motions in pairs of predator-approachingGambusia. Results of experiment 2 suggest that a simple additive combination of the effects of (1) social cohesion in the absence of a visible predator and (2) orientation to a visible predator in the absence of a visible companion can account for the observed frequency of Tit-for-Tat-like motions for pairs of predator-approachingGambusia. It is concluded that predator approach in shoaling fishes is probably a simple by-product mutualism, rather than cooperation maintained by reciprocity in a Prisoner's Dilemma.

Title Social influences on female mate choice in the guppy, Poecilia reticulata: generalized and repeatable trait-copying behaviour Type Journal Article
Year 2005 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 69 Issue 4 Pages 999-1005
Keywords
Abstract In vertebrates, the mating preferences of individual females can be flexible and the probability of a female mating with a particular male can be significantly increased by her having previously observed another conspecific female affiliate and mate with that same male. In theory, such mate-choice-copying behaviour has potentially important consequences for both the genetic and social (`cultural') transmission of female mating preferences. For copying to result in the `cultural inheritance' of mating preferences, individual females must not only copy the mate choice decisions of other females but they also should tend to repeat this type of behaviour (i.e. make similar mating decisions) subsequently and to generalize their socially induced preference for a particular male to other males that share his distinctive characteristics. Here, we show experimentally that individual female guppies, Poecilia reticulata, not only copy the observed mating preferences of other females for particular males, but that the preference now assumed via copying is subsequently repeated and generalized to other males of a similar colour phenotype. These results provide empirical evidence for social enhancement of female preference for particular phenotypic traits of chosen males rather than for the particular males possessing those traits, and thus have important implications for our understanding of the role of social learning in the evolution of female mating preferences and of male epigamic traits.

Title Variability and repeatability of female mating preference in the guppy Type Journal Article
Year 1995 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 49 Issue 6 Pages 1427-1433
Keywords
Abstract Models of inter-sexual selection generally assume heritable variation in mating preferences among females within populations. However, little is known about the nature of such variation. The aim of this study was to characterize quantitatively the phenotypic variation in female preference for a sexually selected male trait, body colour pattern, within a population of the Trinidadian guppy, Poecilia reticulata. Significantly more female guppies preferred the more brightly coloured of two similar-sized males presented simultaneously as potential mates. Mating preference scores for individual females were significantly and positively correlated between two repeated trials on successive days. Females were thus individually consistent in their particular choice of mates, and the calculated repeatability of their mating preference was relatively high. Notwithstanding the aforementioned, significant variation existed among females in the degree of their preference for brightly coloured males. Individual mating preference scores were not normally distributed, but were rather skewed to the right (i.e. towards greater values). These results suggest that additive genetic variation for mating preferences based on male colour pattern is maintained, and the opportunity for the further evolution of both bright male colour patterns and female preference for this trait appears to exist in the study population from the Quare River, Trinidad.

Title Flehmen behaviour in the domestic horse: Discrimination of conspecific odours Type Journal Article
Year 1988 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 19 Issue 3-4 Pages 227-237
Keywords
Abstract American Saddlebred horses were used to test the responses of domestic horses to the odours of conspecifics. In all cases the odours were tested in the absence of the donor animal. Thus the test animal's behavioural responses were concentrated on the olfactory stimuli, and possible interference from donor behaviour was eliminated. Stallions were significantly more responsive than mares and geldings. This was shown in both flehmen and sniffing behaviour to urine/vaginal secretions and in sniffing behaviour to faecal samples. Only stallions were used for subsequent tests. Stallions showed no significant differences in response to the odour of urine/vaginal secretions of an oestrus mare from that when she was not in season. Parameters used for analysis of data were frequency, latency and duration of flehmen as well as duration of responsiveness to samples. In testing for differences in odours between individual mares, two methods were used. The stallions differentiated between samples from individual mares. In some cases this differentiation was exhibited when the stallions were merely presented with the two samples in sequence. In other cases statistically significant differences in response to the odours were shown only by simultaneous presentation of the two samples to the test stallion. Parameters used for data analysis were frequency and duration of flehmen and duration of responsiveness.
