    Beta diversity - Wikipedia

    https://en.wikipedia.org/wiki/Beta_diversity

    In ecology, beta diversity (β-diversity or true beta diversity) is the ratio between regional and local species diversity. The term was introduced by R. H. Whittaker together with the terms alpha diversity (α-diversity) and gamma diversity (γ-diversity). The idea was that the total species diversity in a landscape (γ) is … See more

  2. Beta-Diversität – Wikipedia

    https://de.wikipedia.org/wiki/Beta-Diversität

    Die Beta-Diversität (engl.: diversity, eingedeutscht zu Diversität) ist ein Maß für den Unterschied in der Artenvielfalt zwischen verschiedenen, räumlich in einer Landschaft verteilten Lebensgemeinschaften. Der Ausdruck wird definiert in einer Theorie des amerikanischen Ökologen Robert H. Whittaker (Whittaker 1960) und wird nur im Rahmen der Anwendung seiner Theorie gebraucht. Maß der ökologischen Vielfalt ist hier in erster Linie die jeweilige Artenzahl.

        What is the difference between alpha, beta, and gamma diversity?
        Alpha diversity is just the diversity of each site (local species pool). Beta diversity represents the differences in species composition among sites. Gamma diversity is the diversity of the entire landscape (regional species pool). Among these, alpha and gamma diversity are fairly straightforward. Click to see full answer.

        • Beta = 1: Shares are just as risky as the market (no market sensitivity)
        • Beta > 1: Shares are riskier than the market (high market sensitivity)
        • Beta < 1: Shares are less risky than the market (low market sensitivity)
        • Beta = 0: Shares have no correlation to the market (no market sensitivity)
