Book Description
The Australian vegetation is the end result of a remarkable history of climate change, latitudinal change, continental isolation, soil evolution, interaction with an evolving fauna, fire and most recently human impact. This book presents a detailed synopsis of the critical events that led to the evolution of the unique Australian flora and the wide variety of vegetational types contained within it. The first part of the book details the past continental relationships of Australia, its palaeoclimate, fauna and the evolution of its landforms since the rise to dominance of the angiosperms at the beginning of the Cretaceous period. A detailed summary of the palaeobotanical record is then presented. The palynological record gives an overview of the vegetation and the distribution of important taxa within it, while the complementary macrofossil record is used to trace the evolution of critical taxa. This book will interest graduate students and researchers interested in the evolution of the flora of this fascinating continent.

Book Description
Excerpt from A Memoir on the Palaeozoic Reticulate Sponges Constituting the Family Dictyospongidae So rapid has been the growth of these collections and so generous the disposition of all collectors and students toward the perfecting of this monograph, that to-day we present descriptions of about thrice the number of specific forms recognized as such, seven years ago. This wonderful increase is not especially a matter for congratulation, save that it serves to show the amazing diversity of these siliceous sponges in late Devonian and early Carboniferous faunas. The species and genera are established in accordance with the best standards attainable for these variable organisms. Future collections and observations may show that these divisions are not in all cases sharply defined they will undoubtedly Show that the present account of this organic element in these ancient rocks is far from being complete. In 1892, Mr. Clarke undertook a revision of all previous work upon these fossils and this, with the elaboration of new material, he has carried forward to its present state.

Book Description
With an account of over 6.000 recent and 15.000 fossil species, phylum Bryozoa represents a quite large and important phylum of colonial filter feeders. This volume of the series Handbook of Zoology contains new findings on phylogeny, morphology and evolution that have significantly improved our knowledge and understanding of this phylum. It is a comprehensive book that will be a standard for many specialists but also newcomers to the field of bryozoology.
