Shannon sample
Webb1 Theory 1.1 The Nyquist-Shannon sampling theorem The Nyquist theorem describes how to sample a signal or waveform in such a way as to not lose information. Suppose that we have a bandlimited signal X(t). Bandlimited means that if we were to take the Fourier transform of this signal, X^(f) = FfX(t)g, there would be a certain f Webb1 jan. 2015 · The Shannon-Weaver diversity index is one widely used index for comparing diversity between various habitats (Clarke and Warwick, 2001).It assumes that individuals are randomly sampled from an independent large population, and all the species are represented in the sample (Shannon and Weaver, 1949).The value of the Shannon …

WebbSignal Sampling: Nyquist - Shannon Theorem. Theory. A continuous-time (or analog) signal can be stored in a digital computer, in the form of equidistant discrete points or samples.The higher the sampling rate (or sampling frequency, fS), the more accurate would be the stored information and the signal reconstruction from its samples.

WebbBackground The Shannon diversity index has been widely used in population genetics studies. Recently, it was proposed as a unifying measure of diversity at different levels—from genes and populations to whole species and ecosystems. The index, however, was proven to be negatively biased at small sample sizes. Modifications to the original … WebbShannon's Biodiversity Index Description. Calculates Shannon's Biodiversity Index on a single column of relative abundance data. This metric takes into account both richness …

Well, what you should do depends on what is your goal. Are you interested in the biodiversity of the forest itself, measured via sampling 28 plots, then you should use the complete sample and calculate one Shannon-index. But, if your interest is in how the biodiversity varies over the forest, then maybe you should calculate the 28 indices.
