Perhaps you should try some spelling variations:
"ecologie / methodological" » "ecologies / methodological", "ecologic / methodological", "ecologist / methodological", "ecologie / methodologies"
"ecologicos / methodological" » "ecologicos / methodologies", "ecologico / methodological", "ecologicas / methodological", "ecologicus / methodological"

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 ("ecologicos / methodological"))*.
• Removing quotes may allow a broader search: (( ecologie / methodological ) or ( ecologicos / methodological ))*.
