Sphagnum fuscum hummocks. Known occurrence of "Sphagnum fuscus" are on the map above. The moss inhabits boreal forests and marshlands primarily, and is more likely to be found in colder climates. The moss is also capable of inhabiting areas of relatively high elevation. In recent studies performed in Eastern Europe, it was found that stable carbon and oxygen isotope ratios in α-cellulose of "Sphagnum fuscum" stems subsampled from hummocks and peat plateau profiles are useful indicators for summer temperature and winter precipitation at decadal to millennial timescales. In another study conducted in Alberta, Canada, it was found that "S. fuscum" serves as
Types of plant oils means of extracting essential oils. In this process, used, for example, to extract the onion, garlic, wintergreen and bitter almond essential oil, the plant material is macerated in warm water to release the volatile compounds in the plant. Types of plant oils Plant oils or vegetable oils are oils derived from plant sources, as opposed to animal fats or petroleum. There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils are what are most commonly called vegetable oils.
