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. The book was based on Warming's lectures on plant geography at the University of Copenhagen. It gives an introduction to all major biomes of the world. Its aim was to explain how nature solved similar problems (drought, flooding, cold, salt, herbivory) in similar way, despite using very different raw material (species of different descent) in different regions of the world.
