Perhaps you should try some spelling variations:
"ecologie / methodological" » "ecologies / methodological", "ecology / methodological"
"ecologist / methodological" » "ecologists / methodological", "oncologist / methodological", "ecologies / methodological"
"ecologic / methodologies" » "ecological / methodologies", "oncologic / methodologies", "ecologies / methodologies", "ecologic / methodology"

Try widening your search to All Fields.

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: (((("ecologie / methodological") OR ("ecologist / methodological"))) OR ("ecologic / methodologies")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ecologie / methodological\") OR (\"ecologist / methodological\"))) or (\"ecologic / methodologies\"))".
• Removing quotes may allow a broader search: (((( ecologie / methodological ) OR ( ecologist / methodological ))) or ( ecologic / methodologies )).
• Adding a wildcard symbol may retrieve word variants: (((("ecologie / methodological") OR ("ecologist / methodological"))) or ("ecologic / methodologies"))*.
