迄今为止，许多试图了解物种分布的气候驱动变化或“范围转移”的研究都集中在一个潜在的机制上。虽然单一的绩效指标可能会提供一些见解，但可能不足以准确预测结果。在这里，我们使用了多种性能指标来探索物种范围变化背后的潜在机制。我们研究了热模式的多个性能指标，包括有氧代谢和逃逸速度的多个方面的措施，使用最后的幼虫阶段（puerulus）的东部岩龙虾Sagmariverreauxi作为模式物种。结果表明，好氧范围和逃逸速度对热性能和最适温度有不同的影响。好氧范围的最适温度为27.5°C，最大逃逸速度的拟最适温度为23.2°C。热性能指标的这种差异表明，一种性能指标可能不足以准确预测未来变暖下的整体动物性能。使用多种性能指标和适当的建模技术，可能会导致更准确地预测未来的范围变化，包括气候驱动的物种重新分布的时间和程度。
To date, many studies trying to understand species’ climate-driven changes in distribution, or ‘range shifts’, have each focused on a single potential mechanism. While a single performance measure may give some insight, it may not be enough to accurately predict outcomes. Here, we used multiple measures of performance to explore potential mechanisms behind species range shifts. We examined the thermal pattern for multiple measures of performance, including measures of aerobic metabolism and multiple aspects of escape speed, using the final larval stage (puerulus) of eastern rock lobster Sagmariasus verreauxi as a model species. We found that aerobic scope and escape speed had different thermal performances and optimal temperatures. The optimal temperature for aerobic scope was 27.5°C, while the pseudo-optimal temperature for maximum escape speed was 23.2°C. This discrepancy in thermal performance indicators illustrates that one measure of performance may not be sufficient to accurately predict whole-animal performance under future warming. Using multiple measures of performance and appropriate modelling techniques may lead to a more accurate prediction of future range shifts, including the timing and extent of climate-driven species redistribution.
