As a result, "the models suggest that the pythons are restricted to the vicinity of the Everglades in extreme south Florida…". [10] The models by Dr. Burbrink predict different results than the models of Dr. Rodda because variables such as climatic extremes and seasonal variation create a significant variation in the animals survivability. Dr.
It assumes that niche space is largely saturated with individuals and species, leading to strong competition. Niches are restricted because "neighbouring" species, i.e., species with similar ecological characteristics such as similar habitats or food preferences, prevent expansion into other niches or even narrow niches down.
A vacant niche or empty niche is an ecological niche in a particular ecosystem that is not occupied by a particular species. The issue of what exactly defines a vacant niche and whether they exist in ecosystems is controversial. The subject is intimately tied into a much broader debate on whether ecosystems can reach equilibrium, where they ...
Florida has a big lizard problem. Between lion fish and Burmese pythons, Florida has a lot of invasive species problems -- and the newest is massive Nile Monitor Lizards. Nile Monitor Lizards can ...
Yellow adapts to a new niche restricted to the top and bottom and avoiding competition. In ecology , the competitive exclusion principle , [ 1 ] sometimes referred to as Gause's law , [ 2 ] is a proposition that two species which compete for the same limited resource cannot coexist at constant population values.

At Tampa's Florida Aquarium, employees are relocating animals like penguins to higher ground due to a dangerous storm surge forecast of up to 10 feet or more in the area.
A species' realized niche is usually much narrower than its fundamental niche width as it is forced to adjust its niche around the superior competing species. The physical area where a species lives, is its habitat. The set of environmental features essential to that species' survival, is its "niche." (Ecology. Begon, Harper, Townsend)
