"Model-bottle" experiments introduce an intruder species in a container into a focal fish's territory. A territory holder, Stegastes planifrons, responds by display, chasing and biting at the intruder fish. The territory holder's display includes color changes, fin and body position displays. We might expect a strong response of the territory holder to a conspecific intruder because they have complete resource overlap.Saturday, February 4, 2012

"Model-bottle" experiments introduce an intruder species in a container into a focal fish's territory. A territory holder, Stegastes planifrons, responds by display, chasing and biting at the intruder fish. The territory holder's display includes color changes, fin and body position displays.
