A variety of living things serve as models in biological research, such as in genetics, and in drug testing. Until the 19th century, plants yielded most of the medicinal drugs in common use, as described in the 1st century by Dioscorides. Plants are the source of many psychoactive drugs, some such as coca known to have been used for thousands ...
Anthropogenic biomes, also known as anthromes, human biomes or intensive land-use biome, describe the terrestrial biosphere in its contemporary, human-altered form using global ecosystem units defined by global patterns of sustained direct human interaction with ecosystems.
