Hi there... i do have a set of phytoplankton abundance data (attached) and i would like to do some statistical analysis. in most literature i have seen that researchers usually report the most dominant species when they present their results. i got little bit confused because i really don't know what is the scientific approach that i should use to select the most dominant species from my data set. to make it little bit clear, if i want to do CCA analysis, most of the literature i fallow present only the dominant species in the plot (they did not include all the rare observed species). many thanks in advance
