Partial Submersion

Definition

A condition in which different portions can have aquatic and aerial exposure. A partly submerged resource can provide aerial access to one region while another remains underwater. Position and water-level changes can alter those habitats.

Context
Exposure history

For example, larvae on an exposed region and organisms beneath water may reflect different opportunities for association and different temperature histories.

Terrestrial and aquatic material may represent different associations. A single temperature or organism does not necessarily describe the whole body’s exposure history.
