This work not only covered much of the same ground as Warming did in 1895 and 1896 but in fact also leaned heavily on Warming’s research. Schimper (1898) quoted extensively from more than 15 of Warming’s works and even reproduced Warming’s figures. Yet nowhere did Schimper acknowledge his profound debt to Warming, neither in the list of picture credits, nor in the acknowledgements section of the "Vorwort", nor in his list of major sources, and not even in a footnote! ... Although replete with Warming’s data, it contains few ideas and did not advance ecology beyond what Warming had done earlier.
