Plantesamfund - Grundtræk af den økologiske Plantegeografi, published in Danish in 1895 by
Eugen Warming, and in English in 1909 as
Oecology of Plants: An Introduction to the Study of Plant Communities, by Warming and
Martin Vahl, was the first book to be published having the word
ecology in its title. The book has had a lasting impact on the field of
ecology, particularly in its German translation soon after its initial publication, and in its expanded and revised English translation.
