gammadiversiteetti

Gammadiversiteetti, often referred to as gamma diversity, is a measure of biodiversity that quantifies the total species richness across a collection of habitats or sites. Unlike alpha diversity, which focuses on the species richness within a single, homogenous community, and beta diversity, which measures the difference in species composition between two communities, gamma diversity represents the overarching biodiversity of a larger landscape or region. It is essentially the sum of all species found within that defined geographical area, encompassing the variety of species across all the different habitats within it.

Understanding gammadiversiteetti is crucial for conservation efforts and ecological studies as it provides a broad perspective on the total biological inventory of a region. High gammadiversiteetti can indicate a landscape with diverse habitat types, offering niches for a wide array of species. Conversely, low gammadiversiteetti might suggest a region with fewer habitat types or significant species loss. This metric helps in assessing the overall health and richness of an ecosystem and can be used to compare biodiversity levels between different regions or to track changes over time.
