§Numbers of Rotifers by Fluid Density
§Description:
The data give the numbers of rotifers falling out of suspension for different fluid densities. There are two species, ‘pm’ Polyartha major and ‘kc’, Keratella cochlearis and for each species the number falling out and the total number are given.
§Usage:
rotifer
§Format:
- ‘density’ specific density of fluid.
- ‘pm.y’ number falling out for P. major.
- ‘pm.total’ total number of P. major.
- ‘kc.y’ number falling out for K. cochlearis.
- ‘kc.tot’ total number of K. cochlearis.
