“…In this study, we observed 30 species of rotifers in this lake (but 65 species in the river). The species diversity was lower than that of rotifers in the river; this trend has been reported for other lentic systems too (Nandini et al, ; Ramírez‐García et al, ). This lake also had higher densities of cyanobacteria, particularly Microcystis and Lyngbya , whereas the river had higher densities of diatoms.…”

Planktonic organisms are good indicators of water quality but are rarely used in Mexican riverine studies in spite of the high level of contamination in these lotic waters. In this study, we focused on the plankton of the river Amacuzac in Mexico and a large saline waterbody, Lake Tequisquitengo, which is located in the Amacuzac river basin. We collected samples at three sites in the River Amacuzac and one at Lake Tequisquitengo from May 2015 to March–April of 2016. We analysed the physicochemical variables, coliform bacteria, and biological oxygen demand levels. We also quantified phytoplankton and zooplankton. Our results indicate that the study sites are mesotrophic with high densities of diatoms and cyanobacteria. Among the zooplankton, the dominant organisms were rotifers. The constancy of planktonic taxa was high in the lake but low in the river. The Descy index ranged from 2.9 to 4.5 in the river and from 4.0 to 5.0 in the lake. The saprobic index shows that the system is β‐mesosaprobic. The species diversity was higher in the river than in the lake. Our study shows that plankton can efficiently be used to evaluate the water quality in rivers and lakes.

“…Thus, the waterbody is oligosaprobic to β-mesosaprobic. This is similar to Lake Xochimilco with a saprobic index ranging from1.5 to 2.0 (Nandini et al, 2016). The total rotifer density was however much lower: the mean annual density was 180 ind L -1 and when data of all the five stations were combined, 11 months had mean density of < 500 ind L -1 (oligotrophic condition) while only one month (November) had close to 1000 ind L -1 (mesotrophic).…”

“…However, phosphate levels were high (annual mean 0.64 mg L -1 ). In Lake Xochimilco, Nandini et al (2016) reported nitrate levels of <1 mg L -1 , while phosphates are an order of magnitude higher (2.5-7.8mg L -1 ). On the other hand, Chl a levels in this work varied considerably (2 to 930 µg L -1 ), the mean annual concentration was 110 mg L -1 .…”

“…For example, most works have shown the dominance of Brachionidae (e.g., Keratella, Anuraeopsis) and Polyarthra (Jiménez-Contreras et al, 2009;FigueroaSanchez et al, 2014) in drinking water reservoirs, while in recreational waterbodies such as Llano Reservior, Trichocerca and bdelloids often dominate (Muñoz-Colmenares et al, 2017). On the other hand, in shallow waterbodies such as Lake Xochimilco, species of Brachionus (B. calyciflorus, B. havanaensis, B. angularis and B. caudatus), Keratella (K. cochlearis, K. tropica) and Lecane (L. bulla) are dominant (Nandini et al, 2016;Gayosso-Morales et al, 2017). In deep lakes such as El Sol and La Luna the dominant rotifers are Polyarthra dolichoptera and Conochilus unicornis, bdelloids, Lecane lunaris and Lepadella accuminata (Dimas-Flores et al, 2008).…”

“…For example, in nature, one or more genera such as Anuraeopsis, Keratella, Kellicottia, Brachionus, Polyarthra, Liliferotrocha, Trichocerca, Synchaeta, Cephalodella, Conochilus, Lepadella, Lecane and Ptygura often become highly abundant. They reach >1 ind mL -1 , at least in certain seasons (Duggan et al, 2002;Smith et al, 2009;Nandini et al, 2016;Wen et al, 2017). On the other hand, certain other rotifer genera such as Tripleuchlanis, Cyrtonia, Microcodides, Tetrasiphon, Lindia and Asplanchna rarely exceed 500 ind L -1 (Fontaneto and Melone, 2003;Wallace et al, 2006).…”

To understand the population growth potential of different species of rotifers in nature, field collections through seasons are essential. We sampled zooplankton (and measured selected physicochemical variables) from the Madín reservoir, a high altitude eutrophic urban waterbody from Mexico, every month for a year. Qualitative analysis of zooplankton revealed 28 rotifer species and four cladoceran crustaceans plus one unidentified copepod. Cephalodella catellina (1400 ind L -1 ), Horaella thomassoni (550 ind L -1 ), Conochilus dossuarius (380 ind L -1 ) and Filinia longiseta (25 ind L -1 ) had higher peak density than other rotifers. Based on the concentrations of nitrates and phosphates, chlorophyll a levels or different diversity indices (e.g., Carlson, Shannon-Wiener, Pantle and Buck, Ejsmont-Karabin's TSI Rot ), the waterbody is eutrophic to hypertrophic, depending on the season. In this waterbody we observed high densities of Aphanothece sp. which is a toxic picocyanobacterium. During the blooms of Aphanothece, we also recorded higher densities of H. thomassoni and C. catellina. Based on the gut contents we found that both these rotifer species feed on Aphanothece in this waterbody. This study thus suggests the potential growth of Horaella, Cephalodella, Conochilus and Filinia in this eutrophic reservoir containing blooms of Aphanothece.

Can zooplankton species be used as indicators of trophic status and ecological potential of reservoirs?

The European Water Framework Directive implements the policies to achieve a good ecological status of all European waterbodies. To determine the ecological potential in freshwater environments, abiotic (morphology, physical and chemical variables) and biotics (algae, fishes, etc.) metrics are used. Despite their importance in trophic web, zooplankton was not included as one of the Biological Quality Elements (BQE) to determine the water quality. In the present research, we studied the zooplankton species that can be considered as indicators of trophic status and ecological potential for more than 60 water reservoirs. The data were obtained from more of 300 samples collected during 10 years from reservoirs at Ebro River watershed, which is the largest basin in Spain. According to their physicochemical and biological elements, the trophic status and ecological potential of these reservoirs were established. More than 150 zooplankton species were identified during the study. The results from this research indicate that species that are related with low water quality are: Acanthocyclops americanus, Ceriodaphnia spp., Daphnia cucullata, Daphnia párvula, Diaphanosoma brachyurum, Brachionus angularis, Keratella cochlearis and Phompolyx sulcata. An indicator of moderate quality was Bosmina longirostris, while Daphnia longispina, Ascomorpha ovalis and Ascomorpha saltans were considered as indicators of good water quality. The data obtained suggest that zooplankton species can be used as a valuable tool to determine the water quality status and should be considered, in a near future, as one more of the BQE within the WFD metrics.
