Hutchinson concluded that this size ratio could be used as an indicator of the kind of difference necessary to permit two species to co-occur in different niches but at the same level of the food web. [3] The rule's legitimacy has been questioned, as other categories of objects also exhibit size ratios of roughly 1.3.
The Grinnellian niche concept embodies the idea that the niche of a species is determined by the habitat in which it lives and its accompanying behavioral adaptations. In other words, the niche is the sum of the habitat requirements and behaviors that allow a species to persist and produce offspring.
Another major contribution of Hutchinson was his development of the current definition of an organism's "niche" – as he recognized the role of an organism within its community. Finally, along with his great impact within the discipline of ecology throughout his professional years, Hutchinson also left a lasting impact in ecology through his ...
Evelyn Hutchinson's famous "Homage to Santa Rosalia" was the next foundational paper in the history of the theory. Its subtitle famously asks, "Why are there so many kinds of animals?", and the address attempts to answer this question by suggesting theoretical bounds to speciation and niche overlap.
Economic sociology is the study of the social cause and effect of various economic phenomena. The field can be broadly divided into a classical period and a ...
Herbert Spencer coined the phrase "survival of the fittest", he was an early founder of sociology where he developed the idea of society as an organism, and he created an early precedent for the socio-ecological approach that was the subsequent aim and link between sociology and human ecology.
However, some authors who have contributed most to the formulation of the modern niche concept (Hutchinson, Elton) apparently saw no difficulties in using the term. If a niche is defined as the interrelationship of a species with all the biotic and abiotic factors affecting it, there is no reason not to admit the possibility of additional ...
George Evelyn Hutchinson ForMemRS (January 30, 1903 – May 17, 1991) was a British ecologist sometimes described as the "father of modern ecology." [2] He contributed for more than sixty years to the fields of limnology, systems ecology, radiation ecology, entomology, genetics, biogeochemistry, a mathematical theory of population growth, art history, philosophy, religion, and anthropology.
