fundamental niche造句

• The fundamental niche is the set of environmental conditions under which a species is able to persist.
• Heinz Ellenberg was among the first to experimentally show the importance of a distinction between fundamental niche and realized niche for plants.
• The mathematical representation of a species'fundamental niche in ecological space, and its subsequent projection back into geographic space, is the domain of niche modelling.
• Niche dynamics assume differences among species in their fundamental niche which should give rise to patterns in the abundance and distribution of species ( i . e . their realized niches ).
• In other words, their ability to digest a large range of vegetation allows the Himalayan tahr to have a bigger fundamental niche, and as a result, increases their success as an invasive species.
• It is also important to remember that there is no evolutionary change of the individual species in this case; rather this is an ecological effect of species Y out-competing species X within the bounds of species Y s fundamental niche.
• For instance, species X has a fundamental niche of the entire slope of a hillside, but its realized niche is only the top portion of the slope because species Y, which is a better competitor but cannot survive on the top portion of the slope, has excluded it from the lower portion of the slope.
• The extent to which such modelled data reflect real-world species distributions will depend on a number of factors, including the nature, complexity, and accuracy of the models used and the quality of the available environmental data layers; the availability of sufficient and reliable species distribution data as model input; and the influence of various factors such as barriers to dispersal, geologic history, or biotic interactions, that increase the difference between the realized niche and the fundamental niche.
