Consider the following statements:

Alpha diversity – diversity along the entire range of the mountain slope

Beta diversity – diversity present within each forest of the slope

Gamma diversity – diversity between any two patched and their communities

Which of the terms given above is/are described correctly?

Question

Alpha diversity describes the species diversity within a community at a small scale or local scale, generally the size of one ecosystem. When we casually speak of diversity in an area, more often than not it refers to alpha diversity.
Beta diversity describes the species diversity between two communities or ecosystems. It is at a larger scale, and looks to compare the species diversity between two separate entities that are often divided by a clear geographical barrier like a river or a mountain ridge.
Gamma diversity is studied at a very large scale—a biome—where species diversity is compared between many ecosystems. It could range over areas like the entire slope of a mountain, or the entire littoral zone of a sea shore.
