The Acartia tonsa, a calanoid copepod species, has high survival and thermal acclimation capacity in aquatic environments characterized by temperature variations. Dynamic and static thermal polygon areas of this species are 495 °C and 267 °C for nauplii stage, while adult stage has 747 °C and 411 °C dynamic and static thermal polygon area, respectively. In addition, Acartia tonsa is a copepod species which is more resistant to both high and low lethal temperatures, with its resistance zone of 105 °C and 131 °C for nauplii and adults, respectively. Acartia tonsa nauplii acclimated to 18 °C, 23 °C and 28 °C have lover and upper thermal limit (CTMin-CTMax) of 6.82-26.15 °C, 8.65-29.49 °C, and 11.70-34.10 °C, respectively. This species in the adult stage has a CTMin-CTMax of 4.47-30.30 °C, 6.35-33.94 °C, and 9.92-35.90 °C at acclimation temperatures mentioned above. Its broad dynamic and static thermal tolerance polygon areas and, accordingly, its significant thermal limits allow Acartia tonsa to survive at warm or cold extremes in their natural environment.
中华哲水蚤是一种桡足类浮游动物，在温度变化较大的水生环境中具有较高的生存和热适应能力。该物种的动态和静态热多边形区域分别为 495°C 和 267°C 处于无节幼体阶段，而成年阶段分别为 747°C 和 411°C。此外，中华哲水蚤是一种桡足类浮游动物，对高温和低温都有较强的抵抗力，其无节幼体和成虫的抗性区域分别为 105°C 和 131°C。在 18°C、23°C 和 28°C 下驯化的中华哲水蚤无节幼体的下限和上限热限（CTMin-CTMax）分别为 6.82-26.15°C、8.65-29.49°C 和 11.70-34.10°C。在上述驯化温度下，该物种的成虫的 CTMin-CTMax 分别为 4.47-30.30°C、6.35-33.94°C 和 9.92-35.90°C。中华哲水蚤具有广泛的动态和静态热耐受多边形区域，因此具有显著的热限，使其能够在自然环境中的温暖或寒冷极端条件下生存。
