研究了斑寡杜父鱼的潮汐周期、微生境、温度、微分布格局和热生理与0。snyderi，两个潮池科，被确定。上层潮池的特点通常是温度极端值较大，温度突然变化，这与出现和淹没的时间直接相关。较低的潮汐池往往更稳定，温度极端程度较低。寡杜父鱼（Oligocottus snyderi）仅限于中低潮池，对极端温度的耐受性较差。其上分布边界似乎是由潮池温度极端。斑寡杜父鱼分布广泛，但集中在上层潮池，能够耐受高于上层潮池的温度。这两个物种似乎都没有受到温度突然变化的不利影响。
The relationship between the tide cycle, microhabitat, temperatures, microdistribution patterns and thermal physiology of Oligocottus maculosus, and 0. snyderi, two tidepool cottids, was determined. Upper level tidepools generally are characterized by greater temperature extremes and sudden temperature shifts which are directly related to the periods of emergence and submergence. Lower tidepools tend to be more stable with a lesser extent of temperature extremes. Oligocottus snyderi, which is restricted to middle and lower tidepools, is less tolerant of wide temperature extremes. Its upper distributional boundaries appear to be governed by tidepool temperature extremes. Oligocottus maculosus, which is widely distributed but concentrated in upper level tidepools, is able to tolerate temperatures greater than those occurring in upper pools. Both species do not appear to be adversely affected by sudden temperature shifts.
