| Research Abstract |
Under the predator cue, a spider species did not build asymmetric orb-webs that enables high foraging efficiency but costs information processing ability and long building time. Another spider species exhibited attention-focusing behavior to specific web sector where it found prey more efficiently. On the other hand, simulation model incorporating the constraint of information processing ability failed to exhibit its effect on population dynamics. These results indicate that the constraint of information processing ability has significant effect on spider's foraging ecology, but does not on interspecific interaction.
