We also took flotation samples from middens and other undisturbed contexts.
A short discussion is given to suggest a procedure for deciding in a special case whether this undisturbed region is 'upstream ' or 'downstream'.
Undisturbed core samples were taken at a randomly selected location within each net plot, and at four depths (0, 0.2, 0.4 and 0.6 m).
For pod yield, plants were harvested from an undisturbed net plot area of 4.8 m2 at maturity.
It is a common observation that simple, disturbed, human habitats are more readily invaded by insects and other invaders than complex, undisturbed, natural habitats.
Only three divisions would be worked each year, in rotation, and the fourth was left undisturbed.
Cages were then left undisturbed until completion of development of the first generation.
Ten young adult aphids from cultures were placed on each plant and left undisturbed for 21 days.
