^a Percentage was calculated for each organism on the basis of the corresponding total SSRs count
^b Relative abundance is defined as the total number of SSR s per Mb of sequence analyzed
^c Relative density is defined as a the total sequence length (bp) contributed by each SSR per Mb of DNA of total sequence analyzed
