'Land Bridges - Ancient Environments, Plant Migrations and New World Connections' by Dr Alan Graham
Alan is Curator of Palaeobotany and Plynology at the Missouri Botanical Garden and is the author of several books. Land Bridges tracks the tectonic and climatic changes and evolutionary processes that constitute an important part of, and contribute to a better understanding of, the origin and biotic history of the New World. In the book, Alan describes five long lasting connections (land bridges) between continents. When these were intact, biotas moved between the regions to form floristic and faunal biogeographic relationships, and when they were disrupted, disjunct affinities, such as between eastern Asia and eastern North America, were established.
Paul Manos from Duke University says that Alan is “among the best palaeobotanists in the world.” He has described the topic of the book as “clear and timely” and says that Land Bridges “has great potential to contribute to the biogeographical history of the Americas”.
Henry Hooghiemstra from the University of Amsterdam says that the book “attempts to reconstruct the broad outlines of the geological and palaeobotanical history of the last hundred million years”. He says that “while reading, admiration greatly increased for how Graham is able to make a fascinating story out of such a large bulk of evidence. Few scientists have developed such an impressive, integrated picture of earth history”.
