Hutchinson's "niche" (a description of the ecological space occupied by a species) is subtly different from the "niche" as defined by Grinnell (an ecological role, that may or may not be actually filled by a species—see vacant niches). A niche is a very specific segment of ecospace occupied by a single species.
In this paper this was strong evidence for niche differentiation for interspecific competition, and would also be a good argument for Hutchinson's rule. The simplest and perhaps the most effective way to differentiate the ecological niches of coexisting species is their morphological differentiation (in particular, size differentiation).
The Hutchinsonian niche framework, on the other hand, directly precludes the possibility of there being vacant niches. Hutchinson defined the niche as an n-dimensional hyper-volume whose dimensions correspond to resource gradients over which species are distributed in a unimodal fashion.
Hutchinson's system was one of the most influential revisions of taxonomy in the early twentieth century. Hutchinson is known for his 24 dicta on the classification of flowering plants. A key feature of his third edition in 1973 was based on the habit of the plant, namely that herbaceous plants or Herbaceae are phylogenetically more recent than ...
G. 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.
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 ...
Scout's plant in Blythewood, about 20 miles (32 kilometers) north of Columbia, is expected to open in 2027 and employ up to 4,000 people if the company can hit its goal of making and selling ...
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.
