Ecosystem
The term ecosystem was first used in 1935 in a publication by British ecologist Arthur Tansley. Tansley devised the concept to draw attention to the importance of transfers of materials between organisms and their environment. He later refined the term, describing it as "The whole system, ... including not only the organism-complex, but also the whole complex of physical factors forming what we call the environment". Tansley regarded ecosystems not simply as natural units, but as "mental isolates". Tansley later defined the spatial extent of ecosystems using the term ecotope.
Cedar Creek Ecosystem Science Reserve
Often considered to be the birthplace of the modern science of ecosystem ecology, the research site tested the first radio collars for animal tracking in the 1960s and developed prescribed burning techniques for savannas. The claim is attributed to limnologist Raymond Lindeman (1915-1942) who performed his PhD research on the ecological dynamics of Cedar Bog Lake located in the reserve. Linking Sir Arthur Tansley's coined term "ecosystem" to field research, his studies were influential in forming modern ecosystem ecology.
