The physical isolation of the Antarctic shelf and extreme life conditions contribute to its high degree of endemism. The shelf fauna would, however, be composed of Gondwanan descendants, but also of more recent colonizers. Extreme temperature changes along the climatic history of this region led to the extinction of some lineages, while others flourished. Using molecular phylogenetic methods, this thesis aims to contribute to the general understanding of the evolutionary processes — extinctions, dispersals and in situ diversifications — shaping the biodiversity and geographical distributions of Antarctic amphipods of the families Epimeriidae (genus Epimeria) and Iphimediidae. The systematics of the superfamily presumably including the latter two model families, Eusiroidea, is first revised. Secondly, species boundaries within Epimeria are investigated by using a combination of DNA-based species delimitation methods and morphological descriptions, to ultimately reassess the geographical distribution of species. Finally, the origin of Antarctic lineages, dispersals in/out of the Antarctic shelf and in situ diversification patterns of both Epimeria and iphimediids are explored, using time-calibrated phylogenies. The systematic study of Eusiroidea indicates that at least species belonging to 14 families, including Epimeriidae and Iphimediidae, should be included in a phylogenetically meaningful delimitation of the superfamily. The species richness within Epimeria is greatly underestimated as most nominal species appear to be complexes of geographically-restricted pseudocryptic species. The monophyly of Antarctic Epimeria and (sub-)Antarctic iphimediids suggests that both lineages evolved in isolation since their origin. Both latter clades likely arose from late Gondwanan ancestors and diversified in a cooling environment. (SC - Sciences) -- UCL, 2017

Phylogeography of Southern European Refugia provides the first synthesis of the remarkable diversity, evolutionary complexity, and conservation importance of the flora and fauna in the Mediterranean region, with emphasis on the three major peninsular refugia. The book frames a number of case studies within several introductory and closing chapters that review the development and importance of phylogeographic approaches in evolutionary biology. The book opens with a chapter by the field's founding father, John Avise, reviewing the 25 evolutionary insights that have arisen from the phylogeographic revolution. Key to this perspective is the notion that the multidisciplinary field of phylogeography is serving as an epistemological bridge between the formerly distinct fields of population genetics and phylogenetics. Next, the foremost leaders of plant phylogeography in Europe, Rémy Petit and Giovanni Vendramin provide an extraordinarily comprehensive and studious review of the history of plant organelle genetics and their application in phylogeography. A closing chapter provides an up-to-date review of the caveats, challenges, and future prospects in phylogeography as a discipline. The volume contains both broad scale and regional phylogeographic studies with original data from a range of organisms including trees, mammals, insects, fish, reptiles, and amphibians. Throughout the volume it is clear that phylogeographic studies, especially in the major peninsulas of southern Europe (Iberia, Italy, the Balkans) have provided enlightening insights into the evolutionary complexity and conservation importance of biota occupying Europe's most prominent glacial refugia.

Phylogeography of California examines the evolution of a variety of taxa-ancient and recent, native and migratory-to elucidate evolutionary events both major and minor that shaped the distribution, radiation, and speciation of the biota of California. The book also interprets evolutionary history in a geological context and reviews new and emerging phylogeographic patterns. Focusing on a region that is defined by physical and political boundaries, Kristina A. Schierenbeck provides a phylogeographic survey of California's diverse flora and fauna according to their major organismal groups. Life history and ecological characteristics, which play prominent roles in the various outcomes for respective clades, are also considered throughout the work. Supporting scholars and researchers who study evolutionary diversification, the book analyzes research that helps assess one of the major challenges in phylogeographic studies: understanding changes in population structures shaped by geological and geographical processes. California is one of only twenty-five acknowledged biological hotspots worldwide, and the phylogeographic history of the state can be extrapolated to study other regions in western North America. Further consideration is given to implications for conservation, recommendations concerning the biogeographic provinces that roughly define the state of California, and predictions related to climate change.
