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.

    Quantifying spatiotemporal rhythm of stream metabolism along human disturbance gradients

    Show short summary

    As the first study investigating the effects of WTP discharges on the stream metabolism in Turkey, the results were compared with the previous studies in the literature. The study demonstrated that the WTP discharges increased the mean Rc from −30.6 g O2 m−2 day−1 to −130.9 g O2 m−2 day−1, and had no significant impact on the mean GPP, statistically (15.6 and 9.1 g O2 m−2 day−1 before and after discharges, respectively). Furthermore, the study aimed at statistical modelling the metabolism rates as a function of measured environmental variables. The multiple non-linear regression models of NEM and Rc were derived with high validations (R2 of 74.9% and 66.6%, respectively).

    New water mite species of the genus Rhyncholimnochares Lundblad (Acariformes, Limnocharidae) from Central and South America, with a key to all known species of the genus

    Show short summary

    In the genus Rhyncholimnochares, eleven species new to science are described from running waters in Brazil, Chile, Costa Rica and Ecuador; R. lamellipalpis Lundblad, 1936 is recorded for the first time from Chile. A determination key is given for all known species at the adult/deutonymphal stage.

    Status of fish biodiversity and fishing on Hau River, Mekong Delta, Vietnam

    Show short summary

    Fish biodiversity on Hau River was for the first time thoroughly investigated. One endangered and six vulnerable species were scarcely recorded, only 1-2 times a year among 176 species caught by 5 fishing gears. Trawl and trammel nets are destructive gears but commonly used in fishing. CPUE was found low and declining as in other areas of the Mekong River.

    Effect of sample size on habitat suitability estimation using random forests: a case of bluegill, Lepomis macrochirus

    Show short summary

    This study revealed the influence of sample size on habitat suitability plot by random forest combined with partial dependence plot. Furthermore, we proposed a novel approach “averaged habitat suitability plot”, which enables us to assess habitat suitability even with a small sample size.

    Seasonal variation in functional composition and diversity of cladoceran zooplankton of a lotic eutrophic habitat from India

    Show short summary

    The work provides a first report on seasonal variation in the functional diversity of cladoceran zooplankton from an Indian eutrophic lotic habitat. Functional redundancy was the lowest during the months of high nutrient concentration with certain functional groups completely absent. Moina species were characteristically observed in such months
