In 1989 Fermilab was recognized as a National Environmental Research Park, a protected outdoor laboratory for ecological studies.
Although we have adjusted for measures of area socio-economic status and outdoor occupations, the ecological design leads to the potential for insufficient control of confounding (Morgenstern, 2008).
By far Brookner's most successfully integrated work, that crowning the final years of her life's work, are those outdoor, surviving and ongoing activist and ecological process works that bridge human and animal societies living in symbiotic relationships.

We included 17 semi-ecological, panel, and cohort studies, assessing outdoor air pollutants, such as PM2.5, PM10, NOx, SO2, and O3, and their effects on DNA fragmentation, sperm count, sperm motility, and sperm morphology.
In air pollution epidemiology short-term associations between outdoor air pollution and health are assessed using an ecological time-series design.
While the gains in productivity measured in GE terrestrial crops are predicted to be mirrored in GE algae, the stability of phenotypes and ecological risks posed by GE algae in large-scale outdoor cultivation remain unknown.
