e1“species—area relation for plant species in smaller areas is proposed as a result of intensive examination of species presence in six stands of three undisturbed plant communities in the midwest”
e3“The equations fit rooted data more closely than covered, and it is suggested that the former type of information, being easier to obtain and probably more accurate, is preferable”

Other claims from this paper (4)
- Method / resource The species-area equation fits the observed data for each stand very closely, and fits rooted data more closely than covered data.
- Association The coefficient k varies primarily according to species size.
- Association The exponent z more truly reflects the species richness of the community.
- Association The actual number of species in larger areas falls far below the number the equation predicts.
