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.
Manfredi Nicoletti
Nicoletti is considered a pioneer in Bioclimatic urban and architectural design. In the 1970s his book "L'ecosistema urbano" (The Urban Ecosystem) - a term which he coined - creates a connection between environmental matters and psychological and cultural values. In this volume experts in various disciplines such as psychology, anthropology, biology, engineering, botanics, urban history, economy and acoustics contribute to open a rich discussion on the theme of urban ecosystems.
