‎A magnificent presentation-copy of the first edition of this milestone in the history of ecology, being the first textbook of ecological plant geography ever published and the work that established ecology as a formal scientific discipline. The present copy is inscribed by Warming to G. Sarauw, a Danish-Swedish botanist and archaeologist known for his pioneering interdisciplinary work. Inserted between the front wrapper and the title-page is furthermore a 1-page autograph letter from letter from Warming to Sarauw asking him to criticize and help correct the work before it is published. The letter reveals Warming’s intellectual humility and his scientific approach of peer engagement prior to more formal discussions - not merely seeking publicity or endorsement, but genuinely inviting criticism from a respected peer. The recipient, Sarauw, was a fellow botanist trained in the natural sciences who would later gain fame for his archaeological work at Maglemose, but at the time he was a close colleague within the Danish scientific community. Warming’s ”Plantesamfund” established ecology as a formal scientific discipline on the interaction between organisms and their environment long before the term “ecology” gained general acceptance. The work summed up decades of Warming’s own field research in Brazil, Denmark and Greenland and articulated a structured and comparative approach to vegetation types, ecological adaptations and habitat conditions. Grouping of plants understood not merely taxonomically, but functionally and in relation to their environment, was groundbreaking, marking a decisive turn in botanical science and laying the groundwork for all modern ecology. Biologist R. J. Goodland wrote in 1975: “If one individual can be singled out to be honoured as the founder of ecology, Warming should gain precedence”. (Goodland, R.J. The tropical origin of ecology: Eugen Warming’s jubilee.p. 240-245). “In ""Plantesamfund"" (1895) - (the work offered) - he formulated the program of his research: ""To answer the question: Why each species has its own habit and habitat, why the species congregate to form definitive communities, and why these have a characteristic physiognomy."". The book created an enormous sensation as a new attempt at grouping and characterizing the plant communities - a new phytogeographical term by which Warming meant a group of species forming a physiognomically well-defined unity, such as a meadow. In all essentials the species of a community are subject to the same external conditions arising from the ecological factors. These factors are of a fundamental importance to the ecology ofthe individual plant and the plant community. Considering water to be the most important factor, Warming divided plant communities into four types: hydrophytic, xerophytic, halophytic, and mesophytic."" (DSB XIV, p. 181). In the late 19th century a new interest in nature and the complicated interplay between different species and types arose: “This interest in the influence of the environment on plants gave rise to the new field of ecology, pioneered by the Danish professor Eugen Warming (Warming 1895). Warming’s work had wide-reaching impact. British botanist Arthur Tansley was drawn to ecology after reading Plantesamfund (Warming 1895), commenting: “I well remember working through it with enthusiasm in 1898 and going out into the field to see how far one could match the plant communities Warming had described for Denmark in the English countryside. ….” Tansley would later state that: “Though the organisms may claim our prime interest, when we are trying to think fundamentally, we cannot separate them from their special environments, with which they form one physical system” (1935).” (Mabberly, A Cultural History of Plants in the Nineteenth Century, p99) The work was quickly translated into German, French, English Russian, and Polish, and especially the German translation from 1896 became immensely influential, especially in Britain and North America directly inspiring leading ecologists like Arthur Tansley, Henry Chandler Cowles and Frederic Clements. Even today, Warming’s work continues to be read and is widely regarded as the foundational text of the subject, often viewed as the “bible” of ecological science. ‎

‎Presentation copy of this offprint of Warming’s early work. In 1877, he began publishing the present work in the Botanical Journal. As the title suggests, he presented not only morphological observations but also details on the life conditions of various, mostly Danish, plants, including their development from seed, shoot structure, rhizome formation, and flower biology. He planned to one day compile these studies into a complete natural history of native flowering plants, but never accomplished it. (See Kolderup-Rosenvinge, Eug. Warming). Johannes Eugenius Warming (1841–1924), commonly known as Eugen Warming, was a pioneering Danish botanist widely recognized as one of the founding figures of modern ecology. He authored the first textbook on plant ecology in 1895, introduced the first university course in the subject, and helped define the scope and content of ecological science. In 1975, ecologist R. J. Goodland asserted: “If one individual can be singled out to be honoured as the founder of ecology, Warming should gain precedence” (""The Tropical Origin of Ecology: Eugen Warming's Jubilee""). Warming wrote a number of textbooks on botany, plant geography and ecology, which were translated to several languages and were immensely influential at their time and later. Most important were “Plantesamfund and Haandbog i den systematiske Botanik”.‎

‎Om Skudbygning, Overvintring og Foryngelse.‎

‎(København, 1884). 8vo. In a recent half cloth binding. Nice and clean. 105 pp.‎

‎Rare first edition of Warming's first attempt in life-form classification. The work is considered foundational for later developments in plant ecological morphology and life-form classification, and it laid important groundwork for Warming’s more famous 1895 textbook ""Plantesamfund"" which helped establish ecology as a scientific discipline. The classification was based on his meticulous observations while raising wild plants from seed in the Copenhagen Botanical Garden. Fourteen informal groups were recognized, based on longevity of the plant, power of vegetative propagation, duration of tillers, hypogeous or epigeous type of shoots, mode of wintering and degree and mode of branching of rhizomes.

‎Third German edition, presentation copy, of the founding work on Plant ecology and Plant communities. The present copy was given by Warming to Hjalmar Jensen (1865–1948) a Danish botanist. He studied natural history and geography, worked at the University of Copenhagen and an agricultural station in Karlsruhe and spent several years on tobacco plantations in Java. In 1922 he became a lecturer in microbiology at the Royal Veterinary and Agricultural University in Copenhagen, where he was made professor in 1933. ""Warming was the founder of plant ecology. The term ""ecology"", first used by Haeckel in 1866, was introduced into botany by H. reiter in 1885M but is was Warming who made ecology a preferred field of activity for many botanists. In ""Plantesamfund"" (1895) - (the work offered) - he formulated the program of his research: ""To answer the question: Why each species has its own habit and habitat, why the species congregate to form definitive communities, and why these have a characteristic physiognomy."".

He pointed out that organisms, plant and animal, live in highly developed communities, the tenure of which depends on such things as temperature, rainfall, soil constitution, elevation, and countless other factors. He noted that communities change over time, moving toward what he called ""climax"" communities, which will remain dominant until conditions change. But he also advised that conditions will change, through wildfire, or floods, or man-made alterations, and that such changes are often irreversible, so that a forest turned into grassland will seldom revert to a forest community again.” (Linda Hall)‎

‎First Portugese translation – with the translator’s presentation inscription - of Warming’s pioneering ecological study based on Warming’s fieldwork in Brazil during the 1860s. It represents one of the first systematic attempts to understand vegetation not merely through taxonomy but in relation to environment, function and adaptation. Translator Ferri (1918 – 1985) pioneered field work in Plant Ecology in Brazil. His PhD thesis was one of the first scientific works of an experimental nature in the study of ecology of the vegetation of the cerrados. Warming spent several years (1863–1866) in the region of Lagoa Santa in the state of Minas Gerais, assisting the paleontologist Peter Wilhelm Lund, considered the father of the paleontology of Brazil.During this time, he undertook detailed observations of the local flora, particularly the cerrado vegetation—Brazil’s savanna biome. Unlike many of his contemporaries, Warming did not limit himself to cataloguing species. Instead, he explored how plants interacted with their environment: how they survived drought, coped with fire, and responded to poor soils. His focus on the functional aspects of vegetation-structure, life-form, and adaptation was deeply innovative and helped lay the groundwork for what would later become the discipline of ecology.‎

‎First edition of this work in which Warming further developed his system he first introduced in 1896. Here, he presented a hierarchical system in which he first divided plants into heterotrophs and autotrophs. He then subdivided the autotrophs into aquatic plants and terrestrial plants, which were again divided into different types.‎
