raciborski圆筒精子菌是一种潜在的有毒蓝藻，已经开始出现，或者增加，并且已经主宰了佛罗里达州的一些水体。1997年左右，C. raciborskii在佛罗里达州的Jesup湖开始呈指数增长。结果表明，湖内浮游植物群落的物种丰富度和多样性均呈下降趋势。与该地区的其他湖泊相比，该物种仍然保持着相对动态的种群周期。湖期对黑藻群落的影响与对浮游植物群落的影响不同。相关分析表明，除其他因素外，镁限制可能是影响Jesup湖C. raciborskii生长的重要因素，但在Apopka湖和Griffin湖中不存在。最后，C. raciborskii生长的增加与浮游植物单位磷生物量的增加相关，对湖泊管理和恢复具有重要意义。
Cylindrospermopsis raciborskii is a potentially toxic cyanobacterium that has begun appearing, or alternatively, increasing, and has come to dominate some Florida water bodies. C. raciborskii began exponentially increasing in Lake Jesup, Florida around 1997. As a result, the phytoplankton community in the lake has declined in terms of species richness and diversity. Compared to other lakes in the region this species is still maintaining relatively dynamic population cycles in the take. Lake stage appears to affect C. raciborskii differently than the aggregate phytoplankton community in Lake Jesup. Correlation analysis suggests that magnesium limitation, among other factors, may be an important factor influencing C. raciborskii growth in Lake Jesup, but appears absent in Lake Apopka and Lake Griffin Finally, increases in C. raciborskii are associated with increases in phytoplankton biomass yield per unit phosphorus, having important implications for lake management and restoration.
