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.

  • Seasonal changes in cell size of the dominant diatom species in Lake Biwa

    Show short summary

    We reported the effect of various environmental factors on the cell size change of the dominant diatoms, Aulacoseira ambigua, Aulacoseira granulata, and Fragilaria crotonensis, in Lake Biwa, to know diatoms' seasonal succession and sexual reproduction both of which we have only limited information.

    How diverse is the toolbox? A review of management actions to conserve or restore coregonines

    Show short summary

    Our paper reviews the restoration and conservation strategies applied towards coregonines (e.g., whitefishes, ciscoes) across Europe, Asia, and North America. The highlighted strategies included 1) stocking of hatchery-reared fish, 2) controlling invasive species, 3) translocating fish, 4) restoring habitat, and 5) eliminating harvest or creating protected areas.

  • Cladocera (Crustacea; Branchiopoda) from the Brazilian Cerrado – the richness and species composition for Goiás state

    Show short summary

    Goiás state, situated in the Cerrado biome harbors several water bodies (streams, rivers, wetlands, ponds, reservoirs) belonging to the Paraná, São Francisco, and Tocantins-Araguaia hydrographic regions. However, there are several gaps in the knowledge about the diversity and geographic distribution of aquatic invertebrates in the state, including microcrustaceans of the Superorder Cladocera. In our study, we analyzed data from the literature sources and collected samples in new localities between macrophytes and sediments. The findings suggest the occurrence of 92 species in Goiás state and the presence of five new reports: Scapholeberisfreyi, Grimaldina freyi, Parvalona parva, Chydorusbrevilabris, and Picripleuroxus quasidenticulatus. Alona elisae is endemic for region studied. Such results indicate the megadiversity of cladocerans in Cerrado biome, large than the other countries from the Neotropical zone. Despite the increase in sampling effort for the geographic region studied, many parts of Goiás state are still unsampled. This suggests the still unknown diversity potential for the region.

    Length–weight relationships of the French pikes Esox spp. (Teleostei, Esocidae)

    Show short summary

    Two pike species occur in France: the ubiquitous northern pike Esox lucius and the endemic Aquitanian pike Esox aquitanicus living in small tributaries and coastal catchments in South-West of France. For this last species, there are few knowledges. So, tools and data are needed for its management and stock assessment such as length–weight relationships (LWRs). This study provides the first LWR for E. aquitanicus and compares it with data of French E. lucius. Data for both pike species were collected from 1981 to 2022 during the monitoring of the Departmental Angling Federations and the French Agency of Biodiversity (OFB). Data from 3,657 Aquitanian pikes and 5,413 northern pikes were then provided with average sizes and weights respectively 10.7 cm for 20.2 g and 30.2 cm for 339.8 g. Our study highlights that Aquitanian pike is smaller than northern pike, certainly due to the surface area of habitat and the warmer temperature. The a and b parameters are significatively smaller for the Aquitanian pike than those of E. lucius. This should be explained by the poor environments where it lives (sandy substrates, few aquatic vegetation, low biomass) conferring a lower primary productivity.

Habitat use of the Japanese eel (Anguilla japonica) and marbled eel (Anguilla marmorata) in the large subtropical Pearl River

Show short summary

This study analyzed the population structure and habitat use of the Japanese eel (Anguilla japonica) and the marbled eel (Anguilla marmorata) in the Pearl River based on data collected from 2015 to 2018. A total of 181 Japanese eels and 56 marbled eels were collected, over half of which were middle-sized eels between 255 and 600 mm in length. Although they are sister species, Japanese eels mainly inhabit complex river habitats characterized by high river fractals and coefficients of fluvial facies, while marbled eels mainly inhabit wider and deeper river sections. The results of this study showed that wild Anguilla spp. resources in the Pearl River were extremely low and there was an urgent need for conservation and management of eel resources in south China.

Ecological traits of dragonfly (Odonata) assemblages along an oligotrophic Dinaric karst hydrosystem

Show short summary

Due to the recorded preference for higher water temperature, dragonfly larvae preferred tufa barriers, while they were mostly absent from headwaters of mountainous streams. Favorable microhabitats were inorganic substrates associated with lower current velocity, in contrast to mosses associated with the strongest current. These results represent an important contribution to the knowledge of dragonfly ecology in karstic lotic habitats.

The increasing of maximum lake water temperature in lowland lakes of central Europe: case study of the Polish Lakeland

Show short summary

The study showed significant changes in the maximum annual water temperatures in post-glacial lakes located in Poland in the years 1971-2015. The highest rate of increase in monthly maximum water temperature was recorded in April and the lowest in January and February. The value of maximum water temperature trends was lower than annual air temperature trends.

Longitudinal distribution of macroinvertebrate in a very wet North African Basin: Oued Melloulou (Morocco)

Show short summary

The Melloulou River presented 161 invertebrate taxa, most new for northeast Morocco. Multivariate analyses showed an invertebrate distribution governed by altitude, slope and current velocity in a highly flow dynamic. Three assemblages and a great number of ubiquitous taxa were also found. These findings are of crucial concern for managing actions.

Effects of herbicide mixtures on freshwater microalgae with the potential effect of a safener

Show short summary

Eleven agrochemicals tested on a microalga included a safener added in specific agrochemical formulations. One molecule was 2-fold more toxic than the mixture of all compounds. The safener decreased the toxicity of this herbicide that contains a halogen atom.

Occurrence of potentially toxic cyanobacteria Microcystis aeruginosa in aquatic ecosystems of central Kerala (south India)

Show short summary

The occurrence of M. aeruginosa bloom in two freshwater ponds along central Kerala has been addressed along with the variations in the hydrobiological characteristics of the ecosystem during bloom and non-bloom conditions of the species. Histological studies highlight hepatotoxicity of M. aeruginosa signifying regular monitoring of bloom events in these ecosystems.

Land use change causes environmental homogeneity and low beta-diversity in Heteroptera of streams

Show short summary

Environmental change affected the beta-diversity of the Heteroptera and of Nepomorpha, also negatively affecting both Gerromorpha beta-diversity and richness. These results show that Gerromorpha is more sensitive to physical changes in streams caused by the loss of environmental integrity and deforestation.
