Competing species often coexist at one spatial scale but are found to have distinct distributions at a finer scale of resolution.The Dolly Varden charr and the white-spotted charr are competing species.These two fish species coexist in the same stream,but at a finer scale
A) Each is confined to its own zone due to morphology.
B) They actually compete in sympatry.
C) Both are aggressive but white-spotted charr are more aggressive and Dolly Varden charr avoid them.
D) Each is confined to its own zone due to temperature-mediated competition.
