Estuarine and coastal transformation is as old as civilization yet has dramatically accelerated over the past 150 to 300 years. Reconstructed time lines, causes, and consequences of change in 12 once diverse and productive estuaries and coastal seas worldwide show similar patterns: Human impacts have depleted >90% of formerly important species, destroyed >65% of seagrass and wetland habitat, degraded water quality, and accelerated species invasions. Twentieth-century conservation efforts achieved partial recovery of upper trophic levels but have so far failed to restore former ecosystem structure and function. Our results provide detailed historical baselines and quantitative targets for ecosystem-based management and marine conservation.

Salt Marshes and Salt Deserts of the World

WITH the publication of this volume the whole botanical world, and algologists in particular, owe a special debt of gratitude to Prof. Fritsch. Although ten years have elapsed since the appearance of the first volume, it is no mean achievement under present conditions to have produced this companion work, and both Prof. Fritsch and the Cambridge University Press are to be congratulated on their courage and determination. The Structure and Reproduction of the Algae By Prof. F. E. Fritsch. Vol. 2: Foreword, Phaeophyceae, Rhodophyceae, Myxophyceae. Pp. xiv + 939. (Cambridge: At the University Press, 1945.) 50s. net.
