Freshwater crustaceans are distributed throughout the montane and lowland areas of Colombia, and are therefore a useful indicator group for how aquatic species will respond to climate change. As such, metabolic determination of physiological performance was evaluated for the Colombian pseudothelphusid crab, Neostrengeria macropa (H. Milne Edwards, 1853), over a temperature range inclusive of current temperatures and those predicted by future scenarios in the plateau around the city of Bogotá, namely from 8 °C to 30 °C. The performance results mostly aligned with previous exploratory behavioral determination of the ideal temperature range in the same species, although the metabolism increased at the highest temperature treatments, a point when exploratory behavior declined. These results indicate that this species of montane crab behaviorally compensates for increased thermal stress by decreasing its physical activity, which could have negative predator-prey consequences with changes to community structure as different species undergo climate-mediated geographic range shifts in the region. As this species is endemic to the plateau surrounding Bogotá, it also experiences a number of other stressors to its survival, including infrastructure development and invasive species.

哥伦比亚淡水蟹 Neostrengeria macropa (H. Milne Edwards, 1853) 对温度胁迫的代谢反应 (十足目: Brachyura: Pseudohelphusidae)

淡水甲壳类动物分布在哥伦比亚的山地和低地地区，因此是水生物种如何应对气候变化的有用指标组。因此，在包括当前温度和波哥大市周围高原未来情景预测的温度范围内，评估了哥伦比亚pseudothelphusid螃蟹Neostrengeria macropa（H. Milne Edwards，1853）生理性能的代谢测定，即从8°C到30°C。性能结果大多与先前对同一物种理想温度范围的探索性行为确定一致，尽管在最高温度处理时新陈代谢增加，此时探索性行为下降。这些结果表明，这种山地蟹在行为上通过减少其体力活动来补偿增加的热应激，随着不同物种在该地区经历气候介导的地理范围变化，这可能会随着群落结构的变化而产生负面的捕食者 - 猎物后果。由于该物种是波哥大周围高原的特有物种，它的生存还面临许多其他压力因素，包括基础设施建设和入侵物种。
