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

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