Perhaps you should try some spelling variations:
front deutsche » bonn deutsche, fruhe deutsche, vorwort deutsche
marine species » native species, marine fisheries
four deutsche » fur deutsche, fur deutsch, fruhe deutsche
marine series » marine services, marine fisheries, marine reserves
jahrbuch der » jahrbuch des, jahrbuch fuer, jahrbuch fur
der institut » der institute, dem institut, des institut

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