Hutchinson used the idea of competition for resources as the primary mechanism driving ecology, but overemphasis upon this focus has proved to be a handicap for the niche concept. [20] In particular, overemphasis upon a species' dependence upon resources has led to too little emphasis upon the effects of organisms on their environment, for ...
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.
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.

If one defines a niche as a property of a species, then a niche does not exist if no species is present. In other words, the term appears "illogical". 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.
Getting paid to write may sound easy, but the reality is a little more complicated. Freelance writing can be hard to break into, and the pay can be low (or nonexistent) for beginners.
These days, memes are commonly associated with internet humor, even though as a vague concept they’ve existed since the dawn of humankind. #4 Image credits: Slightly twisted
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.
