AA上剛好有根此篇相符的文章
轉錄過來 順便節錄一些我覺得很特別文句圖片:
We have recently shown that increased nutrient levels might not negatively affect the physiological performance of zooxanthellae as long as all essential nutrients are available at sufficient concentrations to ensure their chemically balanced growth
高營養鹽似乎不會影響蟲黃藻
Most recently, however, we could demonstrate that corals exposed to elevated nitrogen levels were more susceptible to bleaching when exposed to heat and light stress
高硝酸鹽濃度的珊瑚在熱壓力或是光壓力下更容易被漂白
Interestingly, the detrimental effects observed in these experiments could be attributed to the relative undersupply of phosphorus that resulted from the enhanced demand of the proliferating zooxanthellae population rather than to the elevated nitrogen levels themselves
主要的有害影響可能是磷酸鹽的關係而非硝酸鹽
(a)N/P，(b)低N/P高,(c)N高/P低的三種狀態
這張圖顯示，雖然高營養鹽不會影響珊瑚生理，但是營養鹽造成的環境改變卻可能讓珊瑚更不易生存
(eg藻類、以珊瑚為食生物、骨骼脆化、等等) //很明顯沒學過convolution...
總結 營養鹽濃度可能不是光是測量NH4 NO2 NO3 PO4而已
固態的非溶解營養鹽也佔著營養鹽的一席之地 (大大們說的有機鹽?)
雖然營養鹽不會顯著的影響珊瑚的生理
但過高的營養鹽可能助長珊瑚殺手
(高營養鹽造成珊瑚成長快速與脆化 似乎已成此研究員的well-known)
快速繁殖的藻華也可能奪去珊瑚所需的但環境貧脊的營養(PO4, Fe)
而造成珊瑚生態浩劫
