论文摘要
为了评估温度对代谢性能对侵入性CTEMIPIS MNEMIOPSIS LEIDYI的影响,我们将完全适应的成年人暴露于波罗的海西部地区年度变异性的典型条件。我们得出了基础代谢率,它是从成年的Leidyi M. leidyi标本的氧气消耗速率以3.5°C至20.5°C的盐度为22的22的温度。我们发现Q10值为3.67,这意味着在20°C时,碳特异性呼吸速率约为9倍。根据此速率,一个小型的单个口腔宽度长度为20毫米,不会喂养足够的营养储备,可在3°C下生存80天,但在20°C下只有9天。因此,夏末的猎物可用性对于Leidyi M. Leidyi人口存活至关重要。
To evaluate the influence of temperature on metabolic performance on the invasive ctenophore Mnemiopsis leidyi, we exposed fully acclimatized adults to conditions typical for the annual variability of the Western Baltic Sea region. We derived basal metabolic rates from oxygen consumption rates of adult M. leidyi specimens exposed to temperatures between 3.5°C to 20.5°C at a salinity of 22. We found a Q10 value of 3.67, which means that the carbon specific respiration rates are about 9 times greater at 20°C than 3°C. According to this rate, a small-sized individual 20 mm in oral-aboral length, would without feeding have enough nutrient reserves to survive 80 days at 3°C, but only 9 days at 20°C. Thus, prey availability during late summer is critical for M. leidyi population survival.
