These editors provide a stimulating survey of the ways in which mitochondria, plastids, and other cellular organelles replicate. The orderly division and segregation of these organelles is essential for the survival of all eukaryotes and is therefore a topic of importance to a wide range of biologists, from geneticists, via physiologists, to molecular biologists. The first part of the volume examines the mechanism, regulation, and consequences of organelle segregation and division as studied in plant and animal cells. The second part compares the replication of DNA in eukaryote organelles...

Profound progress has been made in the fields of chronobiology and psychobiology within the past decade, in theory, experiment and clinical application. This volume integrates these new developments on all levels from the molecular, genetic and cellular to the psycho- social processes of everyday life. We present a balanced variety of research from workers around the globe, who discuss the funda- mental significance of their approach for a new understanding of the central role of ultradian rhythms in the self-organizing and adaptive dynamics of all life processes. The years since the...
