- 요약Larval life stages are ubiquitous at sea. Yet, we understand quite little about this life stage for many species. This life stage, often small and squishy, is challenging to study, but can last many months and has incredibly important ecological implications. This dissertation focuses on this life history stage, using the bat star Patiria miniata as a model to understand different aspects of larval biology. This dissertation spans three chapters, from a deep dive into larval nervous systems to a population genomics study on this species, and a review that provided context for this work. In chapter one, I show that the larval nervous system of P. miniata is composed of distributed, nonuniform components that have expanding and contracting territories throughout the P. miniata larval stage, when complex morphological changes occur, prior to settlement and metamorphosis. In chapters two and three, I investigate the population genomics of this species - first examining a few unique features of this species' range and genetics in a review. P. miniata encompasses an extensive range gap and genetic disjunction, at distinct locations, within its range along the North Pacific coastline. Chapter two investigates how the scientific community studies coastal disjunctions, both range gaps and genetic divides. It also quantifies the mechanisms that we typically attribute to this phenomenon in the context of coastal marine species. In chapter three, I show that meaningful genetic differences exist across the extensive range gap in this species, but that these are not detectable, or barely detectable, when looking at measures of population structure alone. I also find a genomic region that differs based on sex in this species and describe year-to-year variability in the genomics of this species. This chapter provides an illustrative example of a species in which meaningful genomic differences exist in the absence of strong genetic structure. Cumulatively, these chapters add to our understanding of larval biology, using a set of descriptive molecular studies, along with population genomic approaches that give us a better idea of how dispersal shapes genetic boundaries and divergence over long time periods.
