摘　　要：本文以贝壳作为遮蔽材料,研究不同温度水平和温度变化下海刺猬(Glyptocidaris crenularis)和中间球海胆(Strongylocentrotus intermedius)的遮蔽行为。温度实验结果表明:海刺猬在5°C条件下具有遮蔽行为的个体数以及利用的贝壳数显著少于15°C和25°C两组(P<0.05),而后两组没有显著差异(P>0.05);中间球海胆在25°C下具有遮蔽行为的个体数以及利用的贝壳数要显著少于15°C和5°C两组(P<0.05),而后两组没有显著差异(P>0.05)。温度变化的结果表明:5°C→20°C组海刺猬遮蔽行为所利用的贝壳数最少(P<0.05),另外两组没有显著差异(P>0.05);25°C→20°C组中间球海胆遮蔽行为所利用的贝壳数最少(P<0.05),另外两组差异不显著(P>0.05)。本研究为海胆行为生态学提供了新的思路和信息。We investigated the covering behavior of sea urchins Glyptocidaris crenularis and Strongylocentrotus intermedius in different temperatures and temperature changing schemes.The experimental results show that the number of G.crenularis in covering behavior and the number of shells used for covering at 5°C were significantly less than those at 15 and 25°C(P<0.05).However,the covering behavior of G.crenularis showed no significant difference at 15 and 25°C(P>0.05).The numbers of S.intermedius in covering behavior and shells used for covering were significantly less at 25°C than at 5 and 15°C(P<0.05).However,there was no significant difference in covering behavior of S.intermedius at 5 and 15°C(P>0.05).The number of shells used for covering by G.crenularis in 5→20°C was significantly less than in 15→20°C and 25→20°C(P<0.05),while the latter two groups did not differ significantly(P>0.05).The number of shells used for covering by S.intermedius at 25→20°C was significantly less than 5→20°C and 15→20°C(P<0.05),while the number of shells used by S.intermedius in the latter two groups showed no significant difference(P>0.05).The present study provides new information in behavioral ecology of sea urchins.
