Understanding how ecology and evolution interact resulting in the accumulation of biodiversity is an emerging frontier of integrative research. The accumulation of biodiversity has two controls: origination and persistence of species. The main focus of the literature on the origin of species is the processes that gives rise to new lineages, and relatively less focus is given to lineage persistence. Still, the initial process of population splitting required for species origination may fail to produce new diversity if the newly formed lineages do not persist or go extinct. Instances of ecological and phenotypic diversification within a rapidly multiplying lineage, known as adaptive radiations, represent ideal systems to study both origination and persistence controls on the accumulation of biodiversity. The African Great Lakes harbor unparalleled examples of adaptive radiation. Amongst these, Lake Tanganyika is home to more than 200 endemic cichlid fish species resulting in complex, cichlid-dominated littoral food webs. Here, I present four studies combining population genomic technologies, biodiversity surveys, behavioral assays, and natural history observations of Lake Tanganyikan cichlid fishes. The goal of this integrative work is to provide a unique glimpse into origination and persistence processes driving the exceptional biodiversity accumulation observed within an adaptive radiation. In Chapter One, I examined predictors of population genomic differentiation and its implications for lineage diversification. In Chapter Two and Chapter Three I scrutinize ecological and behavioral drivers of community diversity persistence. Finally, in Chapter Four, I revisit conceptual frameworks on foraging trade-offs mediating the evolution of specialized feeding strategies.

520 $a Comprendre comment l'ecologie et l'evolution interagissent entrainant l'accumulation de biodiversite est une nouvelle frontiere de la recherche integrative. L'accumulation de biodiversite a deux controles : l'origine et la persistance des especes. L'accent principal de la litterature sur l'origine des especes est les processus qui donnent naissance a de nouvelles lignees, et relativement moins d'attention est accordee a la persistance de lignees. Pourtant, le processus initial de division de la population requis pour l'origine des especes peut ne pas produire une nouvelle diversite si les lignees nouvellement formees ne persistent pas ou cessent d'exister. Les exemples de diversification ecologique et phenotypique au sein d'une lignee a multiplication rapide, connus sous le nom de radiations adaptatives, representent des systemes ideaux pour etudier a la fois les controles d'origine et de persistance sur l'accumulation de biodiversite. Les Grands Lacs africains abritent des exemples sans precedent de radiation adaptative. Parmi ceux-ci, le lac Tanganyika abrite plus de 200 especes de cichlides endemiques resultant en des reseaux trophiques littoraux complexes domines par les cichlides. Ici, je presente quatre etudes combinant des technologies de genomique des populations, des enquetes sur la biodiversite, des tests comportementaux et des observations d'histoire naturelle des cichlides du lac Tanganyika. L'objectif de ce travail integratif est de fournir un apercu unique des processus d'origine et de persistance a l'origine de l'accumulation exceptionnelle de biodiversite observee au sein d'une radiation adaptative. Dans le premier chapitre, j'ai examine les predicteurs de la differenciation genomique des populations et ses implications pour la diversification des lignees. Dans les chapitres deux et trois, j'examine les moteurs ecologiques et comportementaux de la persistance de la diversite communautaire. Enfin, dans le chapitre quatre, je revisite les cadres conceptuels sur les compromis dans l'utilization de resources en tant que mediateurs de l'evolution de strategies trophiques specialisees.
