International Journal of Limnology

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.

In 2022 Annales de Limnologie - International Journal of Limnology becomes International Journal of Limnology.
  • Galba truncatula (O.F. Müller, 1774) (Gastropoda, Lymnaeidae): the colonization of new stations on acid soil by low numbers of snails

    Show short summary

    The introduction of Galba truncatula samples, each comprising 5, 10 or 20 snails, in 25 slope rushes and 24 ditches on acidic soil allowed the development of new populations in 10 sites (out of 21) where samples of 5 snails each were used and in the other 28 sites when each sample included 10 or 20 snails.

  • Impact of acute fonofos exposure on skeletal muscle of zebrafish: Histopathological and biometric analyses

    Show short summary

    The present work investigated histological changes in skeletal muscles of zebrafish (Danio rerio) caused by fonofos, an organophosphate insecticide. Fonofos-induced fibrosis, intramyofibrillar vacuoles, disintegrated myofibrils, splitting of myofibers, atrophic and disappeared fibers, histoarchitectural loss, necrosis and progressive decrement in glycogen content were noted. Muscle fiber diameter measurements showed that the fiber diameters of all fonofos exposed groups were decreased in a concentration-dependent manner. These results suggested that fonofos caused significant myoarchitectural impairments in non-target freshwater zebrafish.

  • Spatial and temporal variation in species composition of ciliates communities (Alveolata, Ciliophora) from tropical urban and rural streams

    Show short summary

    This paper builds on community ecology, evaluating spatial and temporal fluctuations in species composition of the protist ciliates community, in rural and urban streams. Particularly, we show that distinct species composition were found in rural and urban streams, considering the main source of impact of each type of stream. Moreover, temporally, the species composition changed between the two periods of the year, considering the limnological distinctions drove by the temperature and rainfall regime.

  • Acute Exposure to the Neonicotinoid Insecticide Imidacloprid of Zebrafish (Danio rerio) Gonads: A Histopathological Approach

    Show short summary

    Depending on the increase in agricultural production, the use of pesticides has also increased worldwide. Imidacloprid is a neonicotinoid pesticide and one of the most widely used in the world. In this study, it was aimed to investigate the histopathological changes in zebrafish ovary and testis tissue caused by imidacloprid, which pollutes the aquatic ecosystem in various ways. It has been shown that imidacloprid causes histopathological changes in the gonads by causing deterioration in the structure of reproductive cells.

  • Effects of ethylene-bis-dithiocarbamate (Mancozeb) on zebrafish (Danio rerio) oocytes

    Show short summary

    Pesticides used to protect plants and animals against the competition of unwanted insects, diseases, and weeds, and pests play a delicate role in living systems. It has adverse effects on the environment and health. The most adverse effects of pesticide derivatives are the reduction in biodiversity, water pollution, and health risks. Mancozeb is an ethylene bis dithiocarbamate (EBDC) pesticide containing manganese and zinc. These pesticides are included in the fungicide group because they are used for treating fungal diseases. In this study, the structure of oocytes developing in female zebrafish exposed to different doses of mancozeb (5 mgL−1, 7.5 mgL−1) was examined. Compared with the control group, it was determined that the number of developing oocytes reduced in the experimental groups. There was a significant increase in atretic oocytes, an increase in the level of degenerate oocytes in a dose-dependent manner, and deformation in oocytes became prominent.
