  • Can't see the “hood” for the trees: Can avian cooperative breeding
           currently be understood using the phylogenetic comparative method'
    • Abstract: Publication date: Available online 10 February 2020Source: Advances in the Study of BehaviorAuthor(s): Andrew Cockburn Cooperative breeding in birds has traditionally been studied via long-term investigations of single populations. In the last two decades the phylogenetic comparative method has been applied to draw generalizations and make predictions about the global distribution of cooperative breeding. These studies generally test single causative factors and have attributed importance to slow life histories, the role of enemies, the way that lifetime fidelity facilitates kin selection, the benefits of help and helping when the climate fluctuates, and the advantages of continuing to live as families after young become nutritionally independent. Surprisingly, no analysis has focused explicitly on the role of the prohibition of dispersal by habitat saturation, the most frequently hypothesized explanation for cooperative breeding when these studies began. In this contribution I critically review this literature, and argue that it has failed to explain obvious phylogenetic and biogeographic patterns in the distribution of cooperation breeding. I identify several common flaws in the way that these studies have been conducted, and suggest that progress may depend on restructuring the question into several components. However, application of appropriate models is likely to fall foul of biases and deficiencies in the data available to populate the analyses, and I argue that a more collaborative, targeted and systematic approach to data collection may be necessary.
       
  • Ecological determinants of sex roles and female sexual selection
    • Abstract: Publication date: Available online 16 December 2019Source: Advances in the Study of BehaviorAuthor(s): Robin M. Hare, Leigh W. Simmons Darwinian sex roles characterized by competitive males and choosy females were long thought to prevail in animals, driven by differences in energetic investment between male and female sex cells. Here we review research on the flower-feeding bushcricket Kawanaphila nartee which has been instrumental in our understanding of the evolution of sex roles. It is now clear that sex roles are determined by many factors, including ecological variables. The sex roles of K. nartee were shown to reverse dynamically according to environmental food availability: when food is scarce, females compete for nuptial gifts and males become choosy; when food is abundant, sex roles are conventional. Interestingly, female K. nartee possess more developed hearing than do males. It has been suggested that female hearing sensitivity is beneficial in intrasexual competition during sex role reversal, when females scramble for access to acoustically signaling males, suggesting that even temporary periods of sexual selection can result in the evolution and maintenance of sex-specific characters in females. Research on K. nartee has underscored the importance of ecology to reproduction by showing that food availability can affect the operational sex ratio and thus sex roles, indicating that sex roles are not necessarily fixed but rather respond plastically to environmental factors.
       
  • Sexual selection and social context: Web-building spiders as emerging
           models for adaptive plasticity
    • Abstract: Publication date: Available online 15 March 2019Source: Advances in the Study of BehaviorAuthor(s): Maydianne C.B. Andrade Phenotypic plasticity is the ability of organisms with a given genotype to develop varied phenotypes under fluctuating environmental conditions. This chapter provides an overview of the conditions under which adaptive phenotypic plasticity is expected to evolve, and the challenge of conducting rigorous tests of hypotheses for such plasticity. It is argued that advances in the field may be facilitated by focusing on species in which some of the complexity of plastic responses is naturally simplified. Here, the focus is on assessing adaptive plasticity of male spiders in response to spatio-temporal heterogeneity in demographic variables that cause changes in the mode and intensity of sexual selection. For web-building spiders in the genera Argiope, Nephila, and Latrodectus, males rarely mate more than once due to sexual cannibalism, male genital mutilation, and arduous, risky mate searching, simplifying predictions about adaptive phenotypes. Population density, the proximity of mates and competitors, and the operational sex ratio may all be linked to variation in the importance of traits that confer advantages in the different episodes of selection that determine male fitness. These links are reviewed in the context of the biology of representative species in each genus. Experimental studies of adaptive plasticity demonstrate that there are robust associations between pheromone-mediated assessment of social context and male development and behavior. The utility of continued study of these spiders with an eye to comparative studies is emphasized.
       
  • Sexual selection in socially-structured, polyandrous populations: Some
           insights from the fowl
    • Abstract: Publication date: Available online 14 March 2019Source: Advances in the Study of BehaviorAuthor(s): Tommaso Pizzari, Grant C. McDonald Sexual selection is widely recognized as the evolutionary agent driving male exaggeration and strategies of intrasexual competition over reproductive opportunities. Two advances have characterized the development of our understanding of sexual selection in recent years. The first was the realization that sexual selection can extend to post-copulatory episodes whenever females mate with multiple males (polyandry). The second concerns the operation of sexual selection in structured population in light of increasing evidence that populations are often non-randomly assembled. Populations of domestic fowl (Gallus domesticus) and red junglefowl (Gallus gallus), which are typically socially-structured and polyandrous, have offered a convenient vertebrate model system to study patterns and mechanisms of sexual selection, providing a helpful counterpoint to studies of socially monogamous systems. Here, we review our understanding of the way sexual selection operates in these populations, with emphasis on recent work focusing on the interrelated implications of polyandry and social structure.

    • Abstract: Publication date: Available online 1 February 2019Source: Advances in the Study of BehaviorAuthor(s): S.K. Sakaluk, K.R. Duffield, J. Rapkin, B.M. Sadd, J. Hunt Nuptial food gifts are an integral feature of the mating systems of a wide variety of insects. A pervasive feature of the majority of these gifts is that they afford the male direct access to the female's physiology. Although in some cases such gifts may represent a form of nutritional investment in females, an alternative hypothesis posits that nuptial food gifts may allow males to manipulate female physiology in favor of male interests. This hypothesis predicts that the chemical composition of nuptial food gifts should be driven by a sexual conflict over offspring paternity.We evaluate this hypothesis by reviewing our accumulated studies on decorated crickets, Gryllodes sigillatus, a species that has illuminated key elements of this evolutionary arms race. Here, nuptial food gifts take the form of a spermatophylax, a gelatinous mass forming part of the male's spermatophore and consumed by the female after mating. We first review the evidence for the two principal sexual conflicts arising from the provision of the spermatophylax: (i) a sexual conflict over female acceptance of gifts, and (ii) a conflict over female remating that appears to be mediated by refractory-inducing substances contained in gifts. We then consider the mechanisms by which these conflicts are mediated, focusing specifically on: (i) multivariate selection analyses of the free amino acid composition of the spermatophylax; (ii) proteomic studies identifying candidate proteins that alter female behavior; and (iii) comparative transcriptomic studies showing how gene expression is altered through nuptial feeding.
       
  • Conformity and over-imitation: An integrative review of variant forms of
           hyper-reliance on social learning
    • Abstract: Publication date: Available online 14 January 2019Source: Advances in the Study of BehaviorAuthor(s): Andrew Whiten Variant forms of conformity and over-imitation have become prominent in the research literatures on the transmission of culture, because each displays particularly high levels of reliance on social learning, potentially much strengthening the fidelity and longevity of traditions. Despite this apparent similarity, the literatures on conformity and over-imitation have rarely cross-referenced each other. The objective of the present review is to rectify this theoretical lacuna, considering in depth both what the two processes share and how they differ. Conformity, originally in the literature on social influence and human culture but addressed increasingly in animal studies, has been dissected into a number of forms distinguished in this review, but most commonly has referred to a disposition to copy majority behaviors in an individual's group or other relevant population. Over-imitation, by contrast, refers to an individual's disposition to copy visibly causally irrelevant components of action sequences even when performed by a single individual. In this review I compare and contrast these two processes, distinguishing a suite of functional and causal factors to explain their occurrence and adaptive significance. Functions appear to span informational, relationship-building and normative contexts. These analyses form a foundation on which to consider why forms of conformity appear increasingly to be widespread in the animal kingdom, whereas over-imitation appears a disposition universal in human cultures yet minimal or absent in non-human animals tested in similar contexts.
       
  • Cowbird cognition: Examinations of the mental skills of a brood parasite
    • Abstract: Publication date: Available online 7 January 2019Source: Advances in the Study of BehaviorAuthor(s): David J. White Modern research in animal cognition considers cognitive skills to be modular processes evolved in response to species' specific ecological demands. Female brown-headed cowbirds (Molothrus ater) like other brood parasites experience a distinct cognitive challenge borne of their breeding biology; they must locate and select viable nests for their offspring. Here I review the information processing capabilities female cowbirds display that afford them the ability to parasitize hosts effectively. I manipulate artificial host eggs in nests and measure female cowbirds' prospecting and laying patterns while they live and breed in large outdoor aviaries. These experiments have revealed that cowbirds track a variety of types of information acquired during prospecting that permits them to evaluate nests, time parasitism effectively, and to copy the nest selection decisions of other females. Recent work has extended these findings to examine individual differences in cognitive skills among female cowbirds, and how these skills generalize to different problem-solving tasks and contexts. The cowbird system serves as an effective system to investigate the mechanisms and function of cognition using an ecologically relevant task directly linked to fitness.
