Johannes Eugenius Bülow Warming

Died 2 Apr 1924 at age 82 (born 3 Nov 1841).Danish botanist whose is regarded as a founder of plant ecology for demonstrating how interactions between plants, animals and other organisms in a habitat form a community shaped by environmental conditions, such as a meadow ecosystem. Although the term ecology was previously coined by Haeckel in 1866, Warming provided a theoretical basis for research in this new discipline within botany. Warming studied what he called environmental factors, including soil, light, temperature and rainfall. His expedition to Brazil (1863-66) yielded a thorough study of the tropical flora. His other travels included Greenland (1884), Norway (1885), the West Indies and Venezuela (1890-92) to study the full range from artic to temperate to tropical habitats.«
