decrease fraction » decrease migration (Expand search), decrease predation (Expand search), decreased production (Expand search)
decrease lodging » decrease during (Expand search), decrease walking (Expand search)
lodging pattern » logging pattern (Expand search), loading pattern (Expand search), foraging pattern (Expand search)
decreases akt » decrease akt (Expand search), decreased akt (Expand search), decreased akt1 (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease fraction decreases akt decrease ) OR ( decrease NOT decrease lodging pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease fraction decreases akt decrease ) OR ( decrease not decrease lodging pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease fraction decreases akt decrease ) OR ( decrease not decrease lodging pattern ))*.
