Seawater carbonate chemistry and shrimp armor and escape kinematics@en

Pandalid shrimp use morphological and behavioral defenses against their numerous fish and invertebrate predators. Their rapid tail-flip escape and rigid exoskeleton armor may be sensitive to changes in ocean temperature and carbon chemistry in ways that alter their efficacy and impact mortality. Here we tested the hypothesis that ocean warming and acidification conditions affect the anti-predator defenses of Pandalus gurneyi. To test this hypothesis, we exposed shrimp to a combination of pH (8.0, 7.7, 7.5) and temperature (13°C, 17°C) treatments and assessed their tail-flip escape and exoskeleton armor after short-term (2 weeks) and medium-term (3 months) exposure. […]藻虾科虾类（Pandalid shrimp）采用形态学与行为学防御策略，抵御种类繁多的鱼类及无脊椎动物捕食者。其快速尾部甩动逃逸行为与坚硬外骨骼护甲，可能会对海洋温度与碳化学环境的变化较为敏感，进而改变防御效能并影响个体死亡率。本研究旨在验证这一假说：海洋暖化与酸化环境会影响格尼藻虾（Pandalus gurneyi）的抗捕食防御能力。为验证该假说，我们将虾类置于pH值（8.0、7.7、7.5）与温度（13℃、17℃）的组合处理环境中，并分别在短期（2周）与中期（3个月）暴露后，评估其尾部甩动逃逸行为与外骨骼护甲性能。[…]
