摘要
摘要 一些水螅物种以其高度的适应性和休眠能力而著称,如Cladonema物种,它们也是很有前途的模式生物。由于盐度会影响水螅物种的发育和分布,因此进一步了解Cladonema物种的耐盐性和休眠能力非常重要。Cladonema digitatum是一种隐性物种,仅在人工环境中被发现。本研究进行了多项实验,以确定盐度对 C. digitatum 息肉和中间体发育的影响,描述 C. digitatum 息肉的休眠和恢复情况,并寻找人工环境中发生 Cladonema 的可能预防和处理方案。结果表明,35-40 ppt的盐度范围对C. digitatum息肉最适宜,而C. digitatum中体则在30-35 ppt的盐度范围内生活得最好;C. digitatum在15、50-60 ppt的盐度范围内会形成月牙体,当盐度上升到35 ppt时会恢复并改变其生存策略,从而增强其耐受性和适应性。Cladonema digitatum介体在面对急剧的高盐和低盐胁迫时也表现出不同的死亡率。综上所述,该研究提供了数字栉水母盐度范围和休眠能力的生态学信息,不仅有助于追踪数字栉水母的野生栖息地,也为消除和预防数字栉水母物种入侵及实验室育种保护提供了理论依据。
Effect of Salinity on the Development and Dormancy of Cladonema digitatum
Abstract
Some hydrozoan species are known for their high adaptability and dormancy ability, e.g., Cladonema species, which are also promising model organisms. Since salinity affects the development and distribution of hydrozoan species, it is important to get further understanding of salinity tolerance and dormancy ability of Cladonema species. Cladonema digitatum is a cryptic species and is discovered only in artificial environments. In this study, multiple experiments have been conducted to determine how salinity affects the development of C. digitatum polyps and medusae, to describe the dormancy and recovery of the C. digitatum polyps, and to find the possible prevention and disposal protocol for the occurrence of Cladonema in artificial environments. As results, salinity range of 35–40 ppt was optimal for C. digitatum polyps, while C. digitatum medusae lived best in 30–35 ppt; C. digitatum would form menonts at 15, 50–60 ppt, revive and change their survival strategies after salinity upturned to 35 ppt, which could enhance their tolerance and adaptability. Cladonema digitatum medusae also showed different death rates when faced with sharp hypersaline and hyposaline stress. In summary, this research provided ecological information about salinity range and dormancy ability of C. digitatum, which not only facilitated tracing the wild habitats of the C. digitatum, but also provided the theoretical basic of elimination and prevention of Cladonema species intrusion and breeding conservation in the laboratory.
期刊介绍:
Estuaries and Coasts is the journal of the Coastal and Estuarine Research Federation (CERF). Begun in 1977 as Chesapeake Science, the journal has gradually expanded its scope and circulation. Today, the journal publishes scholarly manuscripts on estuarine and near coastal ecosystems at the interface between the land and the sea where there are tidal fluctuations or sea water is diluted by fresh water. The interface is broadly defined to include estuaries and nearshore coastal waters including lagoons, wetlands, tidal fresh water, shores and beaches, but not the continental shelf. The journal covers research on physical, chemical, geological or biological processes, as well as applications to management of estuaries and coasts. The journal publishes original research findings, reviews and perspectives, techniques, comments, and management applications. Estuaries and Coasts will consider properly carried out studies that present inconclusive findings or document a failed replication of previously published work. Submissions that are primarily descriptive, strongly place-based, or only report on development of models or new methods without detailing their applications fall outside the scope of the journal.
