Abstract. Although the systematic utility of ecological niche modeling is generally well known (e.g., concerning the recognition and discovery of areas of endemism for biogeographic analyses), there has been little discussion of applications concerning species delimitation, and to date, no empirical evaluation has been conducted.

The intra-specific ecological niche The concept of the ecological niche is a cornerstone of ecological theory [15,16]. It suggests that the ecology of individuals or species with similar requirements (i.e. niches) is adjusted by ‘niche differentiation’ when they occur sympatrically, thereby reducing conflict resulting Review Glossary This niche concept of Hutchinson is designated as multidimensional or hyper-volume niche. In this case the niche can be measured, mathe­matically manipulated and represented in climo-graphs. Concept of Ecological Niche: The ecological niche concept was first formally defined by Hutchinson in 1957.

Clark (1954) distinguished two separate meanings for the term niche, the “functional niche” and the “place niche.” Clark noted that different species of animals and plants fulfill different functions in the ecological complex, and that the same functional niche may be filled by quite different species in different geographical regions.

The future distribution of An. arabiensis in Africa was forecasted by projecting the fit model onto maps of simulated climate change following three climate change scenarios. Ecological niche modelling revealed An. arabiensis to be a climate generalist in the sense that it can occur in most of Africa’s contemporary environmental range. In this chapter, we first trace the history of the concept of ecological niche and see how its meanings varied with the search for a theory of ecology. The niche concept has its roots in the Darwinian view of ecosystems that are structured by BIOL 303 1 Ecological Niches Ecological Niche: 'the total of the adaptations of an organismic unit' Niches identify the 'role of an organism in its community’, or ‘the way a species makes its living’.

Academia.edu is a platform for academics to share research papers. Ecological niche theory has several characteristics. First, the concept may be applied to an individual, a population, or species, although most ecologists focus on the population. However, individual variability within populations is becoming a major concern in biological ecological studies of niche.

We then present how, in contemporary ecology, the niche concept is recruited to explain biodiversity and species coexistence patterns. In parallel, neutralist models, by successfully explaining some ecological patterns without resorting to explanations in terms of niche, have questioned the explanatory virtues of the niche concept.

An ecological niche refers to the interrelationship of a species with all the biotic and abiotic factors affecting it. This definition of niche though has changed over time. Joseph Grinnell in 1917 coined the term niche, which he used as mostly equivalent to a species habitat. Abstract. Although the systematic utility of ecological niche modeling is generally well known (e.g., concerning the recognition and discovery of areas of endemism for biogeographic analyses), there has been little discussion of applications concerning species delimitation, and to date, no empirical evaluation has been conducted.

: 519 The ecological niche is a central concept in the ecology of organisms and is sub-divided into the fundamental and the realized niche. The fundamental niche is the set of environmental conditions under which a species is able to persist. In this chapter, we first trace the history of the concept of ecological niche and see how its meanings varied with the search for a theory of ecology. What an ecological niche is. How species with overlapping niches compete for resources. Resource partitioning to reduce competition.
