Shareholder quorum subsampling

WebbWe employed Shareholder Quorum Subsampling (SQS) as a method for correcting palaeobiodiversity estimates, by taking into account the abundance distribution of taxa. SQS samples evenly from occurrence lists, using Good’s uas an estimation of the ‘coverage’ of the fossil record (20, 31) (see SI 3). Webb22 feb. 2016 · Tetrapod is the name given to any vertebrate animal with four (tetra) legs (pod).There are more than 30,000 living species of tetrapod known today, and this includes many of the animals we are familiar with like mammals, crocodiles, snakes, and birds.
