Manual of Phytogeography

Especiação e seus mecanismos: histórico conceitual e avanços recentes

“…Entretanto, o padrão de distribuição de milhares de organismos filogeneticamente distantes e endêmicos, que apresentam distribuição disjunta, não podia ser explicado pelo dispersionismo. O primeiro pesquisador a reconhecer que esse padrão de distribuição da biodiversidade refletia a fragmentação de uma biota originalmente conectada e testar sua hipótese por meio de um método analítico foi o cientista italiano Léon Croizat (1894Croizat ( -1982 (Croizat, 1952(Croizat, , 1958(Croizat, , 1960(Croizat, , 1964. Seu trabalho de 1958 intitulado Panbiogeography demonstrou que plantas e animais de todo o planeta exibiam disjunção similar e que esses padrões de distribuição correspondiam ao legado relicto de táxons ancestrais amplamente distribuídos no passado.…”

New Zealand panbiogeography: Past, present, and future

“…Panbiogeography was initiated in the 1950's by the French-Italian scholar Leon Croizat (Croizat 1952(Croizat , 1958 as a result of his dissatisfaction with the prevailing methods of study and explanations for the geographic evolution of life. The widespread, uncritical application of the evolutionary theories of Charles Darwin (1859) and Alfred Russell Wallace (1876), particularly by the dominant North American school of evolutionary biogeography (represented by Matthew 1915;Simpson 1940Simpson , 1949Mayr 1946;Darlington 1957) had failed to provide a coherent synthesis of the various locomotory abilities of organisms (means of dispersal) and their different distributions.…”

Timing, exotic terranes, angiosperm diversification, and panbiogeography

“…I shall be very surprised ifCroizat' s researches on carnivorous angiosperm systematics (Croizat 1961;Heads 1984;Craw 1988a) proves to be one of his more successful investigations. His conclusions on their relationships are contrary to all contemporary systems of angiosperm classification (e.g., Takhtajan 1980;Cronquist 1981;Dahlgren New Zealand Journal of Zoology, 1989, Vol.…”

“…It is as well, when evaluating Croizat' s work, and the reaction of the world to it, to bear this historical perspective in mind, since whereas the "Manual of Phytogeography" (Croizat 1952) preceded this phase of transformation, the later major works (Croizat 1958(Croizat ,1961(Croizat ,1964 are dearly contemporary with it. Croizat thus wrote at a time of revolution in the geological world.…”
