Perhaps you should try some spelling variations:
during decreases » warming decreases (Expand search), ageing decreases (Expand search), during increased (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decreases yield » increases yield (Expand search), decreases cell (Expand search), decreases il (Expand search)
yield effect » field effect (Expand search), field effects (Expand search), field efect (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on decrease » on decreased (Expand search), of decrease (Expand search), or decrease (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease _ decrease on decrease ) OR ( decrease during decreases yield effect ))~.
