Editing Obligation (section)

==Other uses==
The term obligate can also be used in a biological context, in reference to species which must occupy a certain niche or behave in a certain way in order to survive. In biology, the opposite of obligate is [[WIKT:facultative|facultative]], meaning that a species is able to behave in a certain way and may do so under certain circumstances, but that it can also survive without having to behave this way. For example, species of salamanders in the family [[Proteidae]] are obligate [[paedomorphs]], whereas species belonging to the [[Ambystomatidae]] are facultative paedomorphs.
