Scott L. Collins, Katherine Suding, Elsa E. Cleland, Michael Batty, Steven C. Pennings, K.L. Gross, James B. Grace, L. Gough, Joe E. Fargione, Christopher M. Clark
2008, Ecology (89) 3534-3541
Summarizing complex temporal dynamics in communities is difficult to achieve in a way that yields an intuitive picture of change. Rank clocks and rank abundance statistics provide a graphical and analytical framework for displaying and quantifying community dynamics. We used rank clocks, in which the rank order abundance for each...
