我設定在26-28
P大,您有沒有興趣來做一個25 26 27 28 哪個對SPS生長速度最佳?
您太看得起我了, 我沒有設備來測試. 況且期刊有實驗結果;-)
這篇給您參考 - 有興趣的話可以去找 reference 裡的其他文章
介紹
1. 珊瑚有適應的溫度, 如果三四個星期中都高於 1°C 適應均溫,珊瑚會白化死亡
2. 溫度改變會有正面與負面的影響. 冬天溫低時珊瑚成長會被低溫所限制. 夏天的時候長得比較快.
註:長得快霰石(骨骼)密度低, 這跟高營養鹽長得快的表現是一樣的, 比較容易碎. 實驗中 acro 在澳洲Lord Howe Island的夏天四個月(海水表面溫度23.35-25.4°C, 比 1999 的 20.5 度還高 )可以長 16.62 ± 1.43 mm. 一個月長 0.4cm.

1. Most corals are adapted to local environmental temperature (Hugheset al. 2003), and typically bleach and die if the local temperature exceeds the normal summer maxima by>1°C for 3 to 4 weeks (Hoegh-Guldberg 1999).
2.Changes in environmental conditions may have both positive and negative effects on coral growth. At some subtropical reefs, coral growth is currently limited by cool winter temperatures (Harriott 1999, Crossland 1981), whereby coral growth is negligible Proceedings of the 12th International Coral Reef Symposium, Cairns, Australia, 9-13 July 2012 4C Coral reef response to multiple stresses: organisms to ecosystems during winter months.during winter months. Consequently, increasing temperatures due to climate hange may greatly extend the growing period, leading to overall to increases in annual growth rates (Cooper et al. 2012).

偶是訂在26~28度，
