    when should we use simpson index and when should we use simpson reciprocal index?
    please make an explanation video for shannon diversity as well. thank you

    Im doing my thesis on a botanical site study. Im having a real hard time calculating the number of species present and how to differentiate between them (especially the pinaceae family) any advice?

    With this index, can I reveal how species diversity in an ecosystem changes over time?

      Yes. If you repeat the process at different points in time it tells you the change.

    For one area I had 15 organisms with 8 species, I got 6.17 for that one
    For another area I had 3 organisms with 2 species, I got 3
    Could you tell me what this infers and why as I’m sure I’ve done the method wrong

    where did the 210 come from?? and why was it 210 and where to find it??? please reply

    • @Science_Sauce
      @Science_Sauce  3 ปีที่แล้ว +1

      N = total number of organisms = 15. “N(N-1)” = 15 x (15-1) = 15 x 14 = 210

    I really thought that when I am gonna use another variation of SDI, I'll gonna get the same results but I am wrong. Now I am even more confused :(((

    If I'm not mistaken, you subtract one because you are working with a sample and not the whole population

    • @therealanton200
      @therealanton200 2 ปีที่แล้ว +2

      No, we do not do this because this method is called Simpson's reciprocal index.

    Bigger the value of d, lower the diversity... U said greater value of d higher the diversity ..it is lil bit confusing ...can u elaborate

    • @Science_Sauce

      There are several versions Simpson’s index - they’re mentioned in the video. This one is Simpson’s reciprocal index and here larger D value indicates greater biodiversity.

    you divide 210 and 92?

  • @aneco2687
    @aneco2687 3 ปีที่แล้ว +2

    I'm afraid you are interpreting the simpsons diversity index wrong. The higher the diversity index D the lower the Diversity. When you calculate 1 - D you can say that a higher value equals a higher diversity.

      There are several versions of Simpson’s diversity index. This video uses Simpson’s reciprocal index and a higher value indicates higher biodiversity.
