Effect Of Sand Grain Size On Burrowing Behavior Of Juvenile Pacific Sand Crabs (Emerita Analoga), Natalie A. Lee, Laura M. Melroy
Biological Sciences
Emerita analoga, Pacific coast sand crabs, are an important biological component of the swash zone ecosystem. They have evolved the ability to burrow into sand, and burrowing speed is commonly used as an indicator of performance relevant for fitness in this species. Sand grain size varies among beaches, and crabs may be better adapted to to burrow in some sand types. We performed a completely crossed 3-factor experiment to determine how the sand grain size associated with beach-of-origin and rearing conditions influence burrowing in coarse and fine sand. Crabs from a fine sand beach and a coarse sand beach were …
