They also require trace amounts of iron which limits phytoplankton growth in large areas of the ocean because iron concentrations are very low.
它们还需要微量的铁,由于海洋中铁的含量非常低,限制了浮游植物大面积的生长。
Other factors influence phytoplankton growth rates, including water temperature and salinity, water depth, wind, and what kinds of predators are grazing on them.
还有其他的因素影响着浮游植物的生长率,包括水温、盐度、水深、风,以及猎食它们的天敌的种类。
Recent research suggests the fear that warming oceans could hamper phytoplankton growth may be real.
最近的研究表明,那种认为海水温度升高会阻碍海洋浮游生物生长的担忧并非空穴来风。
Under certain conditions, excessive phytoplankton growth can result in an area known as a dead zone.
在某些情况下,过度的浮游植物生长可能导致一个被称为死亡地带的区域。
The concentration of phosphate was generally high and it was not possible to be a limiting-factor for the phytoplankton growth in the Bering Sea.
在白令海水域磷酸盐浓度普遍较高,它不可能成为浮游植物光合作用限制因子。
A great amount of sands had sedimentated in the reservoir, and the total suspending matters in the estuary were decreased, which made the illuminative condition for phytoplankton growth improved.
蓄水后沖淡水量的减少导致海域内盐度升高,悬浮物的减少改善了浮游植物生长的光照条件;
