"[A] source of lively discussion and debate among groups interested in plant evolution ... will serve as a stimulus to research over the years ahead. ... I strongly recommend [it] to all evolutionary biologists as valuable reading."--Heredity". . .Levin has written a very good book. . .Whether his more radical propositions prove right or wrong, he has done a great service by crafting with perspicuity and elegant account of a central topic in evolutionary biology."--The Quarterly Review of Biology". . .I can recommend Levin's book primarily as a useful bibliographic overview of the literature on plant speciation of the last 30 years, although with a heavy bias towards population biology."--Plant Systematics and Evolution". . .The Origin, Expansion and Demise of Plant Species represents the first book to be written on the topic for 30 y ears and is likely to be snapped up by plant evolutionists starved for a modern treatment. . .[This book] will be useful for those looking for an up-to-date review of recent work in plant ecological genetics. The book can be used as a springboard into the literature and does contain several proposals that are likely to stimulate discussion,especially in graduate seminars. The species-history approach adopted by Levin is valuable because it points to areas where we lack information, such as the timing of species origins, the nature of thespecies spread, range limits, and the causes of extinction."--Evolution"[A] source of lively discussion and debate among groups interested in plant evolution ... will serve as a stimulus to research over the years ahead. ...
