Rapid warming in the Gulf of Maine may influence the success or invasiveness of the Asian shore crab, . To better predict the effects of climate change on this invasive species, it is necessary to measure its energy dynamics under a range of conditions. However, previous research has only focused on the metabolism of this intertidal species in water. We sampled adult crabs from three different sites and measured their metabolic rates in the air. We show that metabolic rate increases with body mass and the number of missing limbs, but decreases with the number of regenerating limbs, possibly reflecting the timing of energy allocation to limb regeneration. Importantly, metabolic rates measured here in the air are ~4× higher than metabolic rates previously measured for this species in water. Our results provide baseline measurements of aerial metabolic rates across body sizes, which may be affected by climate change. With a better understanding of respiration in , we can make more informed predictions about the combined effects of climate change and invasive species on the northeast coasts of North America.
缅因湾的快速变暖可能会影响亚洲滨蟹的生存或入侵性。为了更好地预测气候变化对这种入侵物种的影响，有必要在一系列条件下测量其能量动态。然而，以前的研究仅关注这种潮间带物种在水中的新陈代谢。我们从三个不同地点采集了成年螃蟹，并测量了它们在空气中的代谢率。我们发现，代谢率随着体重和缺失肢体的数量增加而升高，但随着再生肢体的数量减少而降低，这可能反映了能量分配到肢体再生的时间。重要的是，这里在空气中测量的代谢率比该物种以前在水中测量的代谢率高约4倍。我们的结果提供了不同体型的空中代谢率的基线测量值，而这些测量值可能会受到气候变化的影响。通过更好地了解亚洲滨蟹的呼吸情况，我们可以对气候变化和入侵物种对北美东北海岸的综合影响做出更明智的预测。
