“生殖成本”是指生殖对女性产生的一系列负面影响。脊椎动物繁殖的一个行为代价是丧失或减少运动能力。怀孕个体的运动减少对各种行为，包括运动、捕食、反捕食、迁移和领土巡逻有严重的潜在影响。然而，还没有对海洋无脊椎动物进行比较研究。为了解决海洋无脊椎动物的繁殖成本，我们研究了海参，仿刺参，作为一个模式系统。利用时间推移技术和行为分析软件，对A.从非繁殖期到成熟期。此外，采用超高效液相色谱-四极杆飞行时间质谱（UPLC-Q-TOF-MS）技术，对非繁殖期和生长期动物肌肉组织中的代谢进行了检测。结果表明，繁殖对运动频率和最大速度没有负面影响。然而，移动的总距离和累计移动时间逐渐减少。因此，研究结果表明，运动耐力的丧失是雌性繁殖的行为代价。- 是的此外，我们发现了10个显着的代谢变化，在肌肉组织的动物在生长阶段。这些结果表明，氧化应激和脂质代谢是潜在的生理机制连接生殖和运动性能下降。(C)2017动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
The 'cost of reproduction' refers to a series of negative effects that reproduction has on females. One behavioural cost of reproduction in vertebrates is the loss of or decrease in motility. Diminished locomotion in gravid individuals has serious potential effects on various behaviours, including locomotion, predation, antipredator, migration and the patrolling of territories. However, there have not been comparable studies on marine invertebrates. To address the cost of reproduction in marine invertebrates, we studied the sea cucumber, Apostichopus japonicus, as a model system. Using time-lapse technology and behavioural analysis software, we analysed the locomotor behaviour of A. japonicus from the nonbreeding to the mature stage. In addition, metabolism in muscle tissue of animals between the nonbreeding and growth stage was tested with ultraperformance liquid chromatography and quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS). The results showed that reproduction had no negative effects on locomotion frequency or maximum velocity. However, the total distance moved and cumulative duration of moving gradually decreased. Therefore, the results suggest that loss of locomotor endurance is the behavioural cost of reproduction in female A. japonicus. Additionally, we found 10 significant metabolic changes in the muscle tissue of animals in the growth stage. These results suggest that oxidative stress and lipid metabolism are potential physiological mechanisms linking reproduction and depressed locomotory performance.
