Perhaps you should try some spelling variations:
survival patterns » spatial patterns (Expand search), survival after (Expand search), survival pathways (Expand search)
decrease survival » decreased survival (Expand search), increase survival (Expand search), increases survival (Expand search)
decrease total » decreased total (Expand search), increase total (Expand search), decrease fetal (Expand search)
total decrease » quotas decrease (Expand search), not decrease (Expand search), soil decrease (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

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

• Removing quotes may allow a broader search: (( decrease at decrease total decrease ) OR ( decrease to decrease survival patterns ))~.
