Active migration and passive transport of marine organisms in the fossil record.- Paleoecology and paleogeography of Eocene ostracod faunas from the Nile Valley between Minia and Maghagha, Upper Egypt.- Morphological variability and adaptability in Egyptian Eocene ostracod species Paracosta mokattamensis (Bassiouni).- Insect migration and dispersal with emphasis on Mediterranean ecosystems.- Migration and adaptation of late Cenozoic cold-water molluscs in the North Pacific.- Migration in amphibians and reptiles: An overview of patterns and orientation mechanisms in relation to life history strategies.- Glacial Retreat and its Influence on Migration of Mitochondrial Genes in the Long-toed Salamander (Ambystoma macrodactylum) in Western North America.- The geography of a faunal turnover: tracking the vallesian crisis.- Evaluating the roles of connectivity and environment on faunal turnover: patterns in recent and fossil Iberian mammals.
Why do some animals migrate? How does migration affect the gene pool? This book discusses these questions and more, in light of the high evolutionary costs and risks of mass movement. The editor presents a collection of topics explaining the migration of organisms through many examples of different groups of marine and non-marine organisms, from micro-invertebrates to large mammals.
