Social dominance can influence the allocation of resources in animal groups and has important consequences for individual fitness. In my thesis, I examined the structure, formation, maintenance and consequences of dominance, in the cooperatively breeding pukeko (Porphyrio melanotus melantous: Aves). I first describe a quantitative analysis of pukeko dominance networks (Chapter 2), which included one of the first applications of exponential random graph models in behavioural ecology. This study demonstrated that pukeko form highly ordered dominance hierarchies, and that dominance relationships were influenced by both the attributes of individual birds, as well as self-organizational processes such as winner and loser effects. Additionally, I demonstrated that hatching order has an important influence on the formation of dominance relationships, with earlier hatched chicks achieving higher dominance ranks as adults (Chapter 3). To maintain dominance relationships, pukeko use their red frontal shield as a ‘status signal’, with larger frontal shields indicating more dominant individuals. I showed that sexual dimorphism in frontal shield size is dramatically different in two pukeko populations, probably due to differences in the intensity of intrasexual competition (Chapter 4). Furthermore, by manipulating apparent frontal shield size, I demonstrated that shield phenotype both influences, and is influenced by, social interactions (Chapter 5). This bi-directional relationship between signals and social interactions challenges conventional signalling theory, and has important implications for how honesty is maintained in this signalling system. Finally, I expanded my findings on pukeko colour traits by exploring interspecific patterns of bill colouration in over 1600 bird species (Chapter 6). This study revealed that colourful bills likely evolved as a signal used in competitive interactions, rather than as a sexual signal. Taken together, my research provides a significant advancement in our understanding of the complex nature of dominance in a wild bird, and provides both a methodological and theoretical basis for future studies on animal social behaviour.

▼ S’approvisionner en nourriture est essentiel à la survie et au succès reproducteur. Lorsque les animaux font face à des changements environnementaux brutaux, ils doivent s’ajuster rapidement à leur nouvel environnement et parfois même innover dans leur façon de s’approvisionner. Des processus comportementaux et cognitifs, tels que l’innovation et l’apprentissage, permettent aux animaux d'intégrer de nouveaux comportements à leur répertoire comportemental afin de s'adapter de façon optimale. Les performances cognitives varient entre les individus d’une même population et bien que des études récentes se soient intéressées aux causes de ce phénomène, de convaincantes évidences sont manquantes afin d’expliquer pourquoi ces variations sont maintenues. Au cours de ce mémoire, les questions des pressions de sélection s'exerçant sur les performances d’alimentation par une tâche motrice nouvelle sont abordées afin de mieux comprendre l'évolution des capacités cognitives au sein d'une population captive de diamants mandarins (Taeniopygia guttata). Nous avons tout d'abord testé si les femelles diamants mandarins modifient leurs préférences d'accouplement après avoir observé la performance d'alimentation par une tâche motrice nouvelle des mâles. Afin de déterminer si les femelles sont capables de discriminer entre les mâles sur la base de leur capacité cognitive, nous avons également évalué les performances d’apprentissage de chacune d’elles. En effet, des études ont suggéré qu’il peut être coûteux, spécialement en terme de temps, de discriminer entre des partenaires potentiels sur cette base. La généralisation d’une préférence pour un mâle performant à d’autres mâles possédant le même phénotype permettrait la réduction de ces coûts. Nous avons donc finalement testé si les femelles diamants mandarins peuvent généraliser leur préférence après avoir observé les performances d’alimentation pour une tâche motrice nouvelle d’un mâle. Nos résultats suggèrent que les femelles diamants mandarins ne peuvent évaluer les capacités cognitives d’un mâle par l’intermédiaire de traits indicateurs. Toutefois, nous avons démontré qu’une observation directe des performances d’alimentation d’un mâle guide le choix d’appariement des femelles. Également, nous avons montré que les femelles peuvent généraliser l’apparence du mâle le plus performant et utiliser cette information lors de l’évaluation de nouveaux mâles. La relation entre les performances cognitives et le choix de partenaire pourraient s’expliquer par exemple par une meilleure exploitation de l’habitat, mais nécessite des études plus approfondies.

▼ Les animaux font face à des changements environnementaux brutaux dus aux modifications de milieux liés à l'activité humaine et aux changements climatiques, et doivent s'ajuster rapidement à leur nouvel environnement. Certains processus cognitifs comme l'innovation et l'apprentissage permettent aux animaux d'intégrer de nouveaux comportements à leur répertoire comportemental (flexibilité comportementale), leur donnant l'opportunité d'intégrer un comportement plus optimal pour s'ajuster. Les performances cognitives varient entre espèces et les individus d'une même population et bien que des études récentes se soient intéressées aux causes des variations interindividuelles des performances cognitives, les conséquences restent peu explorées. Dans cette thèse, les questions des pressions de sélection s'exerçant sur les capacités cognitives sont abordées afin de mieux comprendre l'évolution de ces traits au sein d'une population naturelle de mésange charbonnière Parus major. Un nouveau test de résolution de problème a tout d'abord été présenté à des couples reproducteurs directement en milieu naturel. Les résultats ont montré que les couples les plus performants à résoudre la tâche surpassaient les couples les moins performants sur plusieurs mesures de succès reproducteur. Afin de vérifier que la motivation à nourrir les poussins ne biaisait pas cette relation, la taille de nichée a ensuite été manipulée, ce qui n'a pas affecté la performance subséquente des parents. Les couples innovateurs démontraient un meilleur succès reproducteur quel que soit le changement de la taille de nichée subit, ce qui suggère que cette performance influence bien le succès de reproduction, et non l'inverse. De plus, les couples innovateurs approvisionnaient leurs poussins plus souvent que les couples non innovateurs, suggérant que les innovateurs pourraient exploiter leur habitat de façon plus optimale. Dans un troisième temps, plusieurs caractéristiques morphologiques, dont la coloration des plumes, ont été reliées aux performances de résolution de problème et d'apprentissage. Ces liens, bien que complexes et condition-dépendants, pourraient indiquer un rôle de ces performances lors de la sélection sexuelle. Enfin, afin de tester l'effet du parasite sanguin du paludisme sur les traits comportementaux, un médicament contre le paludisme a été injecté à des femelles reproductrices. Cette injection n'a pas modifié leurs performances cognitives mais a augmenté leur niveau d'activité et d'exploration du nichoir en réponse à la tâche de résolution de problème. Ce parasite sanguin, très présent chez les populations depassereaux, pourrait donc expliquer les variations interindividuelles et interpopulationnelles de certains traits comportementaux en milieu naturel, au même titre que dans nombreux autres systèmes hôte-parasites étudiés. Les travaux présentés dans cette thèse ont permis de détailler pour la première fois la relation entre une performance cognitive et le succès reproducteur chez une population aviaire naturelle, une relation robuste… Advisors/Committee Members: Angers, Bernard (advisor), Boogert, Neeltje J (advisor).

▼ Sexual selection is a branch of natural selection which acts upon variation in reproductive success. Sexual selection is a complex field of study in biology as each species has their own mating system and strategies. Models of sexual selection theory are not mutually exclusive, and often times there are multiple layers of selection within a given mating system. For instance, both direct and indirect benefits of sexual selection can occur simultaneously, and selection can act both before and after mating occurs. Postcopulatory sexual selection, which is not as well understood, can be comprised of both the male-male interaction of sperm competition and the male-female interaction of cryptic female choice. Although there are many studies which show the existence of postcopulatory sexual selection, there is limited knowledge of its underlying mechanisms or genetic basis. Although we know of the physical male traits that females prefer, the relationships among male trait, female preference, and postcopulatory sexual selection are often unknown. Here I use Drosophila melanogaster to show accurate alternative measurements for female lifetime reproductive success (Chapter 2) and the genetic architecture underlying lifetime reproductive success (Chapter 3). I found that the short term reproductive success measure of 5 days can accurately predict the lifetime reproductive success of females, and that lifetime reproductive success is a result of additive genetic variation. In Chapter 4, I compared lifetime reproductive success to mating success in a multi-generational study and found that males who were more successful at mating produced sons with lower fitness. I then examined mechanisms of sperm competition, specifically the role of Acps (accessory gland proteins) in sperm competition. I discovered that Acps from the first male to mate are beneficial to the second mated male, contributing to second male advantage (Chapter 5). Lastly, in Chapter 6, I assessed male quality based on five fitness measures and determined male performance in both pre- and postcopulatory sexual selection. I concluded that a combined fitness measure most accurately predicted male offspring production. This thesis characterizes the various factors that contribute to variation in lifetime reproductive success, specifically from a sexual selection perspective.
