We did not undertake a niche modelling assessment of the species throughout its full range, but we hypothesize based on our current results that: either the collected individuals were migrants or, that if they are resident, suitable habitat is extremely scant throughout the region, as determined by our analysis and the suggestion of a realized niche smaller than a fundamental niche, and the species therefore quite rare in Central America.
reads: the realized niche is the subset of the existing fundamental niche that is also suitable in terms of biotic conditions for the species).
The fundamental niche consists of the total potential area that meets all the physical and biological requirements of a species; the actual distribution of a species is determined by a variety of factors such as dispersal, history, and physical barriers--an area described as the realized niche.
Realized niche limitations depend upon the precise commodities of the ecosystem and the nature of the other species involved in the resource partitioning.
Although this micro orientation is justified by the strong empirical findings to date, it seems to rely on an incomplete conception of the niche, one grounded in the realized niche.
latifolia, the test sites encompassed a relatively high proportion of the realized niche of ssp.
