“…It is well-known that the increase in temperature can reduce the generation time and life cycle of several organisms, as well as increase the reproduction and filtration rates of many species (Edmondson, 1965;Rocha et al, 1990;Bunioto and Arcifa, 2007). However, a negative correlation between the D. laevis density and temperature was observed in Lake Jacaré, indicating that the natural fluctuation of this species can also be widely influenced by changes in water temperature, even if in a thermal range considered suitable for tropical cladocerans.…”

The fluctuation of the population of Daphnia laevis in Lake Jacaré (Middle River Doce, Minas Gerais) was monitored monthly (at one point in the limnetic region) for six years (2002)(2003)(2004)(2005)(2006)(2007) as part of the Program of Long-Term Ecological Research (LTER/UFMG). The following parameters were also monitored: water temperature, pH, electrical conductivity, dissolved oxygen, chlorophyll a, total phosphorus, phosphate, total nitrogen, nitrate, nitrite, ammonia, and densities of Chaoborus and ephippia of Daphnia laevis in the sediment.

“…It is well-documented that rotifers are opportunistic species, which exploit resources and rapidly increase their abundance when conditions are favourable (Wallace et al, 2006). Since Edmondson's classic works on Keratella, the growth potential of rotifers has been estimated based on field samples (Edmondson, 1960(Edmondson, , 1965. Under laboratory conditions, the population growth rates of rotifers are routinely estimated using different concentrations of one or two species of algae (Nandini et al, 2007;EspinosaRodríguez et al, 2014).…”

Population growth potential of rotifers from a high altitude eutrophic waterbody, Madín reservoir (State of Mexico, Mexico): The importance of seasonal sampling

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.

L'étude comparée du peuplement zooplanc tonique en milieu naturel et en milieu perturbé, permet de préciser l'influence des modalités d'exploitation de ces retenues sur le développement de la communauté pélagique. En particulier, elle met en évidence pour la série lacustre considérée, un changement de structure de la communauté zooplanc tonique, un appauvrissement spécifique de cette communauté, et une diminution progressive de la productivité de ces milieux.A comparative study of zooplankton in three high-altitude reservoirs and one natural lake in the Pyrenees.Keywords : Zooplankton, kinetic, biomass, production, reservoirs, discharge, Pyrenees. The population dynamics and production of zooplankton have been evaluated in three neighbouring reservoirs (lake Aumar, Orédon, Aubert) and compared with previous results from the natural lake Port-Bielh (2 285 m) which had zooplankton that were specifically similar (dominant species : Polyarthra vulgaris, Mixodiap torn its laciniatits, Cyclops strenuns, Daphnia longispina).The chief difference between the three reservoirs was their thermal regime due to their morphometric and hydrological characteristics.All characteristics can be used to define a series, Port-Bielh-Aumar-Orédon-Aubert, characterised by a progressive diminution in the thermal climate and an increasing instability in the environment. This comparative study of zooplankton populations in a natural and perturbed environment shows precisely the effects of managing these reservoirs on the development of the pelagic community. In particular, the lake series is shown to exhibit a gradual change in the structure of the zooplankton community, a gradual impoverishment of species in the community and a progressive decrease in productivity.As far as the oligotrophic factor is concerned, the discharges and their modalities must be taken into account in the management of the reservoirs.
