Abstract

Coastal algal reef ecosystems, which are formed by the skeletal carbonate of crustose coralline algae (CCA), provide vital habitats for a diverse range of marine organisms and serve as valuable archives of long-term environmental data. Despite the importance of these reef ecosystems, there is currently a lack of available information regarding the accretion rates of CCA in subtropical intertidal zones in the Taoyuan algal reef. We measured the vertical accretion and horizontal growth of CCA cultured in two aquaculture tanks over a 9-month period. The vertical accretion and horizontal growth rate of CCA was approximately 0.29–0.43 and 5.5 μm·day⁻¹ (the extrapolated annual value is equivalent to 0.11–0.16 and 2.0 mm·year⁻¹, respectively). Newly colonized CCA had faster horizontal growth of approximately 110 μm·day⁻¹ (equivalent to 40.2 mm·year⁻¹). These results highlight the slow and gradual process of algal reef ecosystem formation in the subtropical intertidal zones. The CCA had a faster lateral growth rate as seen in the newly settled CCA. These findings contribute to our understanding of the overall growth dynamics of CCA.

台湾培养的甲壳珊瑚藻（Phymatolithon 和 Sporolithon 属）的生长率

海岸带藻礁生态系统是由甲壳珊瑚藻（CCA）的碳酸盐骨架形成的，为各种海洋生物提供了重要的栖息地，并作为有价值的长期环境数据档案。尽管这些珊瑚礁生态系统的重要性，但目前缺乏关于桃园藻礁亚热带潮间带CCA增加率的可用资料。在9个月的时间里，我们测量了两个养殖池中CCA的垂直增长和水平增长。CCA的垂直增长速率约为0.29 ~ 0.43 μm·day−1，水平增长速率约为5.5 μm·day−1（年外推值分别为0.11 ~ 0.16 μm·day−1和2.0 mm·year−1）。新定植的CCA水平生长速度更快，约为110 μm·day - 1（相当于40.2 mm·year - 1）。这些结果突出了亚热带潮间带藻礁生态系统形成的缓慢和渐进过程。在新沉降的CCA中，CCA的横向增长率更快。这些发现有助于我们理解CCA的整体增长动态。

期刊介绍： Marine Ecology publishes original contributions on the structure and dynamics of marine benthic and pelagic ecosystems, communities and populations, and on the critical links between ecology and the evolution of marine organisms. The journal prioritizes contributions elucidating fundamental aspects of species interaction and adaptation to the environment through integration of information from various organizational levels (molecules to ecosystems) and different disciplines (molecular biology, genetics, biochemistry, physiology, marine biology, natural history, geography, oceanography, palaeontology and modelling) as viewed from an ecological perspective. The journal also focuses on population genetic processes, evolution of life histories, morphological traits and behaviour, historical ecology and biogeography, macro-ecology and seascape ecology, palaeo-ecological reconstruction, and ecological changes due to introduction of new biota, human pressure or environmental change. Most applied marine science, including fisheries biology, aquaculture, natural-products chemistry, toxicology, and local pollution studies lie outside the scope of the journal. Papers should address ecological questions that would be of interest to a worldwide readership of ecologists; papers of mostly local interest, including descriptions of flora and fauna, taxonomic descriptions, and range extensions will not be considered.
