Cohort
Definition
A cohort is a group of organisms considered together under a defined origin, sampling or developmental criterion. The grouping should be explicit, because shared collection time or similar size does not automatically establish one deposition event, generation or family.
- Context
- Developmental sampling
For example, large and small larvae in one collection can reflect species or feeding differences rather than proving separate egg-deposition events.
