  1. Rarefaction curves

    In ecology, rarefaction is a technique to assess species richness from the results of sampling. Rarefaction allows the calculation of species richness for a given number of individual samples, based on the construction of so-called rarefaction curves. This curve is a plot of the number of species as a function of the number of samples.

    What is rarefaction in anatomy?
    1 : the action or process of rarefying. 2 : the quality or state of being rarefied especially : an increase in porosity areas of rarefaction in the bones. 3 : a state or region of minimum pressure in a medium transversed by compressional waves (as sound waves) the eardrum vibrates according to the compressions and rarefactions of the sound wave.

    What is the rarefaction curve?
    The rarefaction curve is a plot of the number of species against the number of samples. This curve is created by randomly re-sampling the pool of N samples several times and then plotting the average number of species found on each sample.

    What is a rarefaction wave?
    A common rarefaction wave is the area of low relative pressure following a shock wave (see picture). Rarefaction waves expand with time (much like sea waves spread out as they reach a beach); in most cases rarefaction waves keep the same overall profile ('shape') at all times throughout the wave's movement: it is a self-similar expansion.

    What does the rarefaction plot show?
    Salvador Ramirez-Flandes Deviram Garlapati Thank you so much!! Hi, the rarefaction plot is showing the number of indivudal OTUs identified in a given rarefaction. It will divide your sample in many samples with varying number of reads (Rarefied samples) and use it to calculate an alpha-diversity metric accross this range of sample sizes.

    rarefaction, in the physics of sound, segment of one cycle of a longitudinal wave during its travel or motion, the other segment being compression. If the prong of a tuning fork vibrates in the air, for example, the layer of air adjacent to the prong undergoes compression when the …

      Rarefaction is the reduction of an item's density, the opposite of compression. Like compression, which can travel in waves (sound waves, for instance), rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave (see picture).
