种群如何适应环境变化是生态学的一个中心话题,但很少有人在水生系统中研究生物体表型的长期变化。在这项研究中,我们利用古湖泊学分析,研究了深见池(日本长野县)的水蚤从最初建立阶段开始的形态变化。我们测量了 ephippia 和 D 亚化石的形态特征。 pulexand 将结果与早期研究中评估的种群动态进行了比较。 2000年代初,pulex在湖中建立了稳定的种群。 ephippia的长度在2000年代中期显着增加,然后在最近减少,而​​作为体型指标的后腹爪的长度没有显示出显着的变化。这表明,尽管平均体型没有变化,但在2000年代中期,它们的成年体型更大,成熟时间推迟或进入休眠期较晚。 Chaoborus 的亚化石和历史记录表明,在 2000 年代中期,食浮游生物的鱼类数量较少,而 Chaoborus 幼虫的数量比最近时期更为丰富。这些结果表明 D. pulex适应性地改变表型特征以响应所研究的湖泊中捕食者群落的变化。
How a population adapts to environmental changes is a central topic in ecology, but long-term changes in the phenotype of an organism have rarely been studied in aquatic systems. In this study, we examined the morphological changes inDaphnia pulexfrom the initial establishment stage, using paleolimnological analysis, in Lake Fukami-ike (Nagano Prefecture, Japan). We measured morphological traits of ephippia and subfossils ofD. pulexand compared the results with the population dynamics assessed in an earlier study.D. pulexestablished a stable population in the lake in the early 2000s. The length of the ephippia significantly increased in the mid-2000s and then decreased more recently, whereas the length of the post-abdominal claw as a proxy of body size did not show significant changes. This suggests that their adult body size was larger, and the time to maturity was delayed or the shift to the dormant phase got later in the mid-2000s, although the mean body size did not change. Subfossils ofChaoborusand the historical records suggest that planktivorous fish were less abundant andChaoboruslarvae were more abundant in the mid-2000s than in more recent periods. These results suggest thatD. pulexadaptively changed phenotypic traits in response to changes in the predator community in the studied lake.
