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.

  • A new diatom index to assess ecological quality of running waters: a case study of water bodies in western Anatolia

    Show short summary

    Trophic index Turkey (TIT) tested in this study provides information about assessment of running waters. Compared with EPI-D, TIT was more competitive and had a well-fitting regression with logTP. EQR based on TIT showed a negative significant correlation with logTP. TIT could be a useful biological metric for freshwater monitoring.

  • Physiological and biochemical responses of Egeria densa to different sediment redox conditions

    Show short summary

    This study assessed the physiological and biochemical effects of a submerged macrophyte, Egeria densa, under different sediment redox conditions. The study will improve our ability to predict the dynamics of wetland aquatic vegetation and thus facilitate the formulation of wetland management and restoration strategies.

  • Response of a littoral macroinvertebrate assemblage to a persistent hydrological drought in a permanent mountain shallow lake from northwestern Spain

    Show short summary

    Current projections predict an intensification of hydrological drought as a consequence of climate change, but we know very little about the potential effects on aquatic communities. Our work on La Baña (SW León Province, Spain), a mountain lake suffering from increased water seepage due to geological reason, assessed the effect of drought on the littoral macroinvertebrate community. The most relevant change was a drop in richness values: rarefaction curves showed that richness in lake in 2014 was only slightly higher than in the temporary pond, and much lower than in the lake in 2005 or 2006. However, the assemblage composition did not shift towards a fauna typical of temporary waterbodies. These results might indicate that the resistance of the assemblage was high enough to prevent changes in the first moments (differences between 2005 and 2006 were small), but not after nine years of sustained summer drought.

  • Variability in ostracod communities (Crustacea, Ostracoda) in connected and isolated tropical floodplain lakes

    Show short summary

    Floodplains mostly consist of primary and secondary river beds, connecting channels and lakes that are either isolated from rivers and channels for most of the year, or lakes that are connected to rivers and channels for most (or all) of the year. We hypothesize that the differences in invertebrate communities, as calculated by beta-diversities, will be higher in isolated than in connected lakes. We use ostracod communities in the pleuston of the floating macrophyte Eichhornia crassipes in the Upper Paraná River Floodplain to test this hypothesis.

    We have observed significant differences in species composition between the two types of lakes. However, although beta diversity values are indeed slightly higher in isolated than in connected lakes, these differences are not significant. This lack of clear effect of isolation on beta diversity could be owing to the fact that the period of isolation since the last homogenizing flood pulse had not been long enough, or because differences in degree of isolation become altogether insignificant in periods of low water flow.

  • Depth distribution of zooplankton in relation to limnological gradients under different stratification and interannual regimes in a deep, tropical crater lake

    Show short summary

    Lake Bosumtwi showed distinct vertical structuring of the water column but seasonal variation was low. Chaoborus performed extensive diel vertical migration. Most species dwelt continuously in the epilimnion with no migratory activity. Strategies for coexistence were spatial overlap among competitors and spatial segregation with predators.
