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.
Limiting similarity (informally "limsim") is a concept in theoretical ecology and community ecology that proposes the existence of a maximum level of niche overlap between two given species that will allow continued coexistence.
The process and concept of ecosystem engineering are related to niche construction, but the former relates only to the physical modifications of the habitat whereas the latter also considers the evolutionary implications of physical changes to the environment and the feedback this causes on the process of natural selection. Ecosystem engineers ...
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.

For nearly three decades, the person behind the brutal murder of a 15-year-old girl found in a Montana river in 1996 remained a mystery. After a breakthrough using modern DNA testing, a suspect ...
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 ...
Defensive end Aidan Hutchinson, Detroit's best defensive player and an NFL Defensive Player of the Year candidate, was injured on a sack of Cowboys quarterback Dak Prescott in the second half.
