Perhaps you should try some spelling variations:
vibration decreases » maturation decreases (Expand search), starvation decreases (Expand search), vegetation decreases (Expand search)
decrease vibration » decrease migration (Expand search), disease vibration (Expand search), decrease predation (Expand search)
decrease the » decreases the (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease of (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)
in objects » in object (Expand search), on objects (Expand search), and objects (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 the decrease vibration decreases ) OR ( decrease at decrease in objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease the decrease vibration decreases ) OR ( decrease at decrease in objects ))*.
