The effect of the presence and angular position of a refuge on the direction and kinematics of mechanically-induced escape responses was observed in staghorn sculpins Leptocottus armatus using high-speed video. The results showed that the angular position of the refuge did not affect locomotor performance (speed and acceleration), although it did affect the escape trajectories. Therefore, the angular position of a refuge can modulate the direction taken by the L. armatus during the early stages of their escape response and this response can be affected by both repulsive (i.e. threats) and attractive (i.e. refuges) points of reference.
利用高速视频观察了在鹿角杜父鱼(Leptocottus armatus)中,避难所的存在及其角位置对机械诱导逃避反应的方向和运动学的影响。结果表明,避难所的角位置虽不影响运动表现(速度和加速度),但会影响逃避轨迹。因此,避难所的角位置可以调节鹿角杜父鱼在逃避反应早期所采取的方向,并且这种反应会受到排斥性(即威胁)和吸引性(即避难所)参考点的影响。
