“…The phytoplankton in TGR has been extensively studied, especially the seasonal variation in phytoplankton species (Zeng et al, 2006;Zhou et al, 2011), algal blooms (Wang et al, 2011b;Ye and Cai, 2011), eutrophication (Zheng, 2007;Zhong et al, 2005), and the relationship between biotic and abiotic factors (Bi et al, 2010;Zhang et al, 2010).…”

“…The increase in species richness seen during the dry season in the present study might be related to the physical characteristics of that season, such as greater solar radiation, higher temperatures and less precipitation, all of which favor the growth of algae (Kivrak 2006;Marques et al 2012). In addition, water velocity tends to decrease during the dry season (Nogueira 2000;Zeng et al 2006;Cunha et al 2013). The occurrence of a larger number of taxa during the dry season has also been reported for other Brazilian rivers, such as the Urubuí (Aprile & Mera 2007), Paraibuna and Pomba (Soares et al 2007).…”

“…In this context, it is necessary to increase research efforts regarding phytoplankton biodiversity, especially in the Amazon, where there are plans for the construction of hydroelectric plants, which significantly alter the flow of rivers and, consequently, the dynamics of aquatic organisms (Zeng et al 2006). In addition, this is one the least served regions of Brazil regarding sewage treatment, as noted by Cunha et al (2004;2005) and Agostinho et al (2005).…”

During the various hydrological periods in 2011, we studied the phytoplankton along an 87-km stretch of the Araguari and Falsino rivers, which are located in the eastern Brazilian Amazon, in the state of Amapá, Brazil, the most ecologically preserved state in the country. In the study area, the aquatic ecosystem is under pressure from human activities such as, mining, hydroelectric power generation and urbanization, which contrast with the surrounding areas that are designated for biodiversity conservation. The aim of this study was to characterize the composition, frequency and richness of algae species and also to identify spatial-temporal patterns of taxa distribution. During the study period, we identified 185 taxa (136 species in 49 genera). The division Chlorophyta (class: Zygnematophyceae) presented the greatest number of taxa, whereas the division Rhodophyta accounted for only 1% of the taxa recorded. Most of the species identified (69%) were classified as sporadic in occurrence. The few taxa that were classified as common belonged mainly to the group Bacillariophyta. Species richness was greatest richness in the lentic stretches (in a reservoir) and in November (during the dry season). Of the 185 taxa identified, 174 are new records for the state of Amapá.

“…One of the most obvious negative impacts of this kind of hydromodification on water quality is the enhanced algal growth. Due to the combined consequences of reduced flow velocity and prolonged hydraulic retention time, increased phytoplankton biomass within Three Gorges Reservoir has been observed since the closure of the dam (Zeng et al 2006). The construction of the sluice gate at the outlet of Lake Chaohu was suggested as a leading cause for the increased eutrophication of the lake ).…”

Eutrophication in a Chinese Context: Understanding Various Physical and Socio-Economic Aspects

Eutrophication is now a ubiquitous water quality impairment in China. The first step toward restoration of eutrophicated water bodies is a marked reduction of nutrient loadings in their drainage basins. However, the combination of a number of physical and socio-economic factors is now producing compounded increases in nutrient loads while the nutrient assimilation capacities of natural systems are decreasing. Meanwhile, most of the lakes in densely populated part of China are shallow and very susceptible to anthropogenic alteration. Therefore, in spite of ascending efforts in eutrophication control upward trends of algal blooms in both fresh and coastal waters have been observed for the past two decades. Huge knowledge gap exists in our understanding of the sources and pathways of nutrient losses to aquatic ecosystems. Successful water quality restoration of China's eutrophic waters relies not only on more resource input but also more emphasis on basic, integrated, and management-oriented research.
