| 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。 |

| Abstract: |
| 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. |
