Environmentalism: sociological/political, more interdisciplinary, a philosophy/social movement. Basic ecology: not meant to directly benefit humans or other species. Applied ecology: finds solutions to environmental problems. Salamander mating season: proximate, weather/temperature, ultimate, good food source and wetness for offspring. Cause is a loaded word: experimentation is needed to determine cause. Experiments (medium realism/medium control: understanding cause through manipulation. Mesocosm experiments: meant to replicate nature more accurately than normal experiments. Field experiments: manipulating actual environment on a large scale. Treatments not applied randomly: not necessarily natural, many are created or influence by humans. Amphibians ( both lives : anurans (frogs and toads) Endemic: only found in one geographic area.
