The Need of Standardized Quantitative Methods in Forest Biology

Ecology, 1929
Biologists in every field are today finding themselves continually hampered by the incompleteness of their information concerning the biotic factors of environment. Furthermore, much of the information now available is not of the maximum possible value because the basic data are often not comparable.

The reproductive biology of the dendrochirote sea cucumberCucumaria frondosa(Echinodermata: Holothuriodea) using new quantitative methods

Invertebrate Reproduction & Development, 2001
Summary Previous studies on the reproductive cycle of echinoderms have used the gonadal index and descriptions of histological preparations of the gonad to determine reproductive state. The size frequency distributions of oocytes are also commonly used to delineate the various phases of the reproductive cycle.
