of Ceratophyllum echinatum over time
[Plots of numbers of papers mentioning Ceratophyllum echinatum (filled column
histogram and left hand axis scale) and line of best fit, 1926 to 2006
(complete line, with equation and % variation accounted for, in box on the left
hand side); Plots of a proportional micro index, derived from numbers of papers
mentioning Ceratophyllum echinatum as a proportion (scaled by multiplying by
one million) of the total number of papers published for that year (broken line
frequency polygon and right hand scale) and line of best fit, 1926 to 2006
(broken line, with equation and % variation accounted for, in broken line box
