How does creationism explain niche biomes with unique species?

A species' niche is basically its ecological role, which is defined by the set of conditions, resources, and interactions it needs (or can make use of). The competitive ... for identical resources). Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning. read more

Some creationists admit a certain amount of "micro evolution", explaining how bacteria appear to evolve in lab conditions, and how species subject to selective breeding (like dogs and pigeons) can have some wide differences that breed true. read more

A realized niche is smaller than a fundamental niche. The realized niche is only the part of a resource that the species actually uses. In the example in the book, all five species of Warblers ate insects from a different part of the tree, so although they shared the same fundamental niche, each had their own unique realized niche. read more

The abiotic or physical environment is also part of the niche because it influences how populations affect, and are affected by, resources and enemies. The description of a niche may include descriptions of the organism's life history, habitat, and place in the food chain. read more
