Perhaps you should try some spelling variations:
marine reserves » marine resources, marine fisheries
institute four » institute fur, institutes fur, institute after
marine species » native species, marine fisheries
four deutsche » fur deutsche, fur deutsch, front deutsche
jahrbuch dlr » jahrbuch der, jahrbuch fur, jahrbuch fuer

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: ((jahrbuch dlr) OR (jahrbuch des)) institute four deutsche ((marine reserves) OR (marine species))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((jahrbuch dlr) OR (jahrbuch des)) institute four deutsche ((marine reserves) or (marine species))~".
• Adding a wildcard symbol may retrieve word variants: ((jahrbuch dlr) OR (jahrbuch des)) institute four deutsche ((marine reserves) or (marine species))*.
