Abstract

Laboratory experiments were conducted to determine the thermal tolerance of the living shallow-water and intertidal gastropods from lagoons in Bahrain and Saudi Arabia, in the western Arabian Gulf. Our experimental trials, run in duplicate using a semi-controlled thermal incubator, quantify the thermal limits of two species of gastropods, the tropical periwinkle Planaxis sulcatus (Born, 1778) and the mud creeper Pirenella conica (Blainville, 1829), which are commonly found in the region. The two species display different thermal tolerances to heat exposure during this study. In the case of Planaxis sulcatus, we observe that half of the test specimens that are fully exposed to the air enter an inactive state or become comatose at about 39 °C, while half of specimens that are fully immersed in sea water become immobile around 42 °C. For Pirenella conica half of test specimens that are fully exposed enter become inactive at about 37.5 °C, while for specimens that are fully immersed in sea water this temperature is around 45 °C. At 60 °C total mortality is observed with no indication of recovery. These observations have implications for climate change predictions in the western Gulf region, as water temperatures in the lagoon already reach 42 °C in summer, while the substrate temperatures on mud flats exposed during low tide exceed the lethal limit of the gastropods during the summer months.

西阿拉伯湾潮间带腹足类动物的耐热性
我们进行了实验室实验,以确定阿拉伯湾西部巴林和沙特阿拉伯泻湖中生活的浅水和潮间带腹足类动物的热耐受性。我们的实验使用半控制热培养箱重复进行,量化了两种腹足类动物的热极限,即该地区常见的热带长春花 Planaxis sulcatus(Born,1778 年)和泥爬虫 Pirenella conica(Blainville,1829 年)。在这项研究中,这两个物种对高温的耐受性不同。就 Planaxis sulcatus 而言,我们观察到完全暴露在空气中的测试样本有一半在约 39 °C 时进入不活动状态或昏迷,而完全浸泡在海水中的样本有一半在约 42 °C 时失去活动能力。对于 Pirenella conica,完全暴露在空气中的一半试样在 37.5 °C 左右进入非活动状态,而完全浸泡在海水中的试样在 45 °C 左右进入非活动状态。在 60 °C 的温度下,标本完全死亡,没有恢复的迹象。这些观察结果对海湾西部地区的气候变化预测有影响,因为夏季泻湖的水温已经达到 42 °C,而退潮时暴露在泥滩上的底层温度超过了腹足类动物在夏季的致死极限。

期刊介绍: The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
