“…A. granulata is a classical indictor of eutrophic waters. It is often the dominant species in eutrophic freshwater areas around the world [23][24][25]. In our study, the total abundance of A. granulata was 1.3×10 5 filaments L 1 at Xiangtan and Changsha, which is comparable to levels in other studies [24] and close to the level (3.15×10 5 filaments L 1 ) reported in the Pearl River in China [24].…”

The frequency of algal blooms has increased in the mid and downstream reaches of the Xiangjiang River (Hunan, China), one of the most heavily polluted rivers in China. We identified the bloom-forming species in a bloom that occurred mid-late September 2010. In addition, we determined the extent of metal bioaccumulation in the algae and measured the toxicity of the algae using a mouse bioassay. Water samples were collected at upstream (Yongzhou), midstream (Hengyang), and downstream (Zhuzhou, Xiangtan, and Changsha) sites. The dominant species was Aulacoseira granulata, formerly known as Melosira granulata.

“…DRSi concentration changed very little during the spring sampling period (Fig. 4) and the slight decrease during summer did not deplete DRSi to levels thought to be critical to the growth of Aulacoseira (Gibson et al 2003;Kilham & Kilham 1975). The concentration of DRSi was quite similar at the periods of maximum A. ambigua abundance during each sampling period but filament length was higher in spring.…”

Aulacoseira ambigua abundance and filament length were measured weekly during spring and autumn bloom periods in Trout Lake, Wisconsin, USA. In addition, several chemical and biological variables thought to influence A. ambigua growth were assessed. Results of the field-based observations were complimented with controlled laboratory experiments to evaluate the effects of phosphorus availability on A. ambigua growth. Relative to the autumn bloom period, A. ambigua colonies were generally larger and more abundant in spring prior to the termination of the bloom in June. Chlorophyll-a concentrations indicated that other phytoplankton were also more abundant during the spring bloom. Batch culture experiments indicated that increased phosphorus availability during the spring bloom contributed to the seasonal increase in A. ambigua filament length and abundance. Increase in A. ambigua filament length in response to increased phosphorus availability is discussed as a mechanism that may increase nutrient removal through sedimentation and subsequently decrease the efficiency of nutrient regeneration in higher productivity lakes.

“…For example, they play an important role in carrying resting propagules down into the sediment deposits as shown by the classical study of Stockner & Lund (1970). Furthermore, diatom resting stages may be grazed by benthic animals (Gibson et al 2003). Another effect of sediment mixing is that substances important for phytoplankton growth (e.g.…”

Many phytoplankton species produce resting cysts, forming 'seed banks' on lake sediments until they germinate and provide inocula (recruitment) for future pelagic populations. We have addressed the question of whether the littoral or the profundal zone provides the inoculum for planktonic populations in a eutrophic and dimictic lake (Lake Erken, Sweden). Our hypotheses were that high temperature, light, and sediment mixing would enhance recruitment. Also, we hypothesized that recruitment from littoral sediments would be greater than from profundal sediments. In situ recruitment traps were utilized to compare littoral and profundal recruitment, while laboratory experiments were performed to analyze which factors were most important. Seven common taxa were investigated: Asterionella formosa (Bacillariophyceae), Ceratium hirundinella (Dinophyceae), Microcystis botrys, M. wesenbergii, Anabaena sp., A. solitaria, and A. lemmermannii (Cyanobacteria). Our main findings were that light and sediment mixing were the most important factors in triggering and enhancing recruitment in the laboratory. Temperature and sediment origin (littoral/profundal) had a significant effect on recruitment only for A. lemmermannii and C. hirundinella, respectively. The field experiments showed that recruitment at the littoral site was much higher than at the profundal site, where little or no recruitment occurred. Together, these results strongly suggest that littoral sediments in temperate lakes provide inocula for most phytoplankton populations, likely due to favorable light conditions and high sediment mixing.
