Glossary
Rumination: A digestive process typified by the chewing of cud, which enables plant cellulose walls to be broken down in the stomach for energy. The vegetation is stored, regurgitated for more chewing, then broken down by specialised bacteria.
Subspecies: a population usually restricted to a geographical area that differs from other populations of the same species, but not to the extent of being classified as a separate species.
