Perhaps you should try some spelling variations:
decrease predation » decrease prevention (Expand search), increased predation (Expand search), decreased production (Expand search)
predation decrease » reduction decreases (Expand search), retention decrease (Expand search), predation defence (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease owing » decrease lodging (Expand search), decrease in (Expand search), decrease with (Expand search)
owing pattern » wing pattern (Expand search), sawing pattern (Expand search), using pattern (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease AND decrease predation decrease ) OR ( decrease during decrease owing pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease predation decrease ) OR ( decrease during decrease owing pattern ))*.
