Annales de Limnologie - International Journal of Limnology

Annales de Limnologie - International Journal of Limnology publishes papers on the ecology of freshwater systems, ranging from studies of aquatic organisms, physical and chemical works which relate to the biological environment, to ecological applications and frameworks for water management directives.

Journal founded by University Paul Sabatier, Toulouse in 1964.

    The early catfish catches the worm: predation of Corydoras aeneus (Siluriformes, Callichthyidae) on freshwater nematodes

    Show short summary

    A small tropical catfish (Corydoras aeneus) was able to dampen the populations of different nematode species dwelling homogeneous sandy sediment in laboratory–controlled aquaria. This study contributes to better understand the ecological relevance of the fish-nematode trophic channel.

  • Combined effects of oxytetracycline concentration and algal food level on the life-table demography of Brachionus calyciflorus (Rotifera)

    Show short summary

    The increase in Scenedesmus obliquus density from 2.0 × 106 to 4.0 × 106 cells mL−1 decreased the magnitude of stimulatory effects of lower concentrations of OTC but enhanced that of inhibitory effects of high concentration of OTC on the survival, asexual reproduction and population growth of Brachionus calyciflorus. So did the decrease in algal density from 2.0 × 106 to 1.0 × 106 cells mL−1.

  • Spatial and temporal limnological changes of an aquaculture area in a neotropical reservoir

    Show short summary

    The seasonal variations influence water quality parameters on neotropical reservoir. The biochemical oxygen demand is controlled by the interaction between the layers of water and the seasons of the year. The fish farm in these places, when kept within the capacity of supporting of the environment, does not alter the quality of water.

  • Ecological classification of the freshwater Ostracoda (Crustacea) based on physicochemical properties of waters and habitat preferences

    Show short summary

    CCA explained 57.4% of correlation between ostracod species and environmental variables when water temperature, redox potential, pH and electrical conductivity were the most effective factors on species. Species with wide tolerance ranges were found in variety of habitats and distributed more frequently in broader geographic ranges than other species.

  • Effects of vertebrate and invertebrate predators on the life history of Daphnia similis and Moina macrocopa (Crustacea: Cladocera)

    Show short summary

    Although most studies use the genus Daphnia to evaluate phenotypic plasticity in cladocerans, other genera might also respond to predator infochemicals. In this study fish infochemicals increased the size at primipara, clutch size, net reproductive rate and longevity in Daphnia and Moina. Conversely, Chaoborus infochemicals affected only the net reproductive rates and longevity of cladocerans. Non-daphniid cladocerans may display similar responses to Daphnia when exposed to predators. However, as Daphnia is usually underrepresented in tropical lakes, studying other genera might offer new insights into predator-prey relationships and food webs in lake ecosystems.
