What is the Hutchinsonian niche?

The Hutchinsonian niche is a "n-dimensional hypervolume," with the dimensions being environmental circumstances and resources that determine the requirements of an individual or a species to practice "its" way of life, specifically for its population to survive. These requirements are called "niches." The term was coined by American paleontologist Charles Doolittle Walcott in 1892 while discussing the ecological roles of fossil plants. He said that each plant occupied a "niche" within the rock where it was found.

According to this view, all organisms live within their environment, and the ones that can adapt themselves to these environments will have the best chance of survival. Organisms therefore adjust their behaviors and appearances according to their surroundings, which allows them to find a suitable place in their ecosystem quickly without wasting energy on things that aren't necessary for their survival. An organism's ability to fit into its environment is known as its "niche adaptation." For example, plants that can grow in different types of soil will have more options for finding a place in their ecosystem, which increases their chances of survival. Animals that can change how they look through evolution (e.g., camouflage) or learn new behaviors (e.g., learning) can do the same. They too can find a place in their ecosystem faster than those who don't have these abilities.

What is a multidimensional niche?

This is known as the basic niche, or the multidimensional zone (also known as a hypervolume) of environmental tolerance in which an individual or species might theoretically live or establish healthy populations.... Multidimensional niches can vary in different parts of the same habitat - for example, grasslands may have more than one type of microclimate, so their hypervolumes overlap but are not identical.

What is a functional niche?

As a result, this functional niche relates to a species' location in food webs and trophic chains, and the idea is particularly significant for ecosystem ecology. Each dimension of the niche space indicates an environmental characteristic that may or may not be relevant for a species' survival. For example, if a species is restricted to dry habitats, it can be said that it has one kind of ecological niche. However, if we look at other niches such as dietary or temporal, we see that this species fits all of them.

A functional niche is the set of physical conditions under which a species is able to survive and reproduce. This means that every species has a functional niche. A functional niche can be thought as the intersection of the ecological niches of its members of a community. The term "functional" here refers to the fact that the properties considered are those involved in the performance of the organism or group of organisms. In other words, what matters is not so much the identity of the organisms occupying the different niches but rather their ability to interact with each other through competition or cooperation. A species with a narrow functional niche is likely to become extinct when its environment changes or gets replaced by another species with different requirements. A wide functional niche on the other hand, means that the species can cope with many different environments.

In conclusion, a species' functional niche is the set of environmental conditions under which it is able to survive and reproduce.

How did Evelyn Hutchinson describe the ecological niche?

More than a half-century ago, G. Evelyn Hutchinson suggested characterizing a species' ecological niche as an abstract mapping of population dynamics onto an environmental space, the axes of which are abiotic and biotic elements that impact birth and death rates. He called this mapping "abiotically compatible" or "incompatable." A species is considered to be abiotically compatible with another if it can coexist in the same area and is biotically incompatible if it cannot coexist. Thus, two species are said to have a competitive exclusion relationship if they do not overlap in their abiotically compatible areas and therefore cannot coexist.

Competitive exclusion occurs when two or more species compete intensely for the same resources and thus prevent each other from occupying suitable habitat effectively. Because some species will tend to dominate over others due to differences in growth rate, survival rate, or reproduction rate, competitive exclusion is thought to result in a state where none of the species can increase in abundance significantly because they are forced into different habitats where they cannot interact. However, competitive exclusion does not always lead to extinction - for example, two plants may compete for sunlight that only one can occupy at a time - so this outcome is not guaranteed even if all conditions for competitive exclusion are present.

In addition to competitive exclusion, other factors may also cause a reduction in biodiversity.
