Preserved Baseline
Definition
Material retained under a documented treatment to support later examination of the collection state. Preserved material records aspects of the sample before additional rearing or handling changes occur. Collection location, time and preservation treatment should remain linked.
- Context
- Collection-time documentation
For example, promptly preserved material can retain information about collection-time stage while a separate live portion continues developing during rearing.
Preservation itself can affect measurements. A baseline is useful only when its treatment and suitability for the intended examination are understood.
