  • Increasing risk of water quality deterioration in a typical inland lake of China

    Show short summary

    This study integrated years of field measurements and Landsat-5/8 images to assess the water quality of a typical transport lake in China and revealed the increasing risk of water quality deterioration in recent years. The exploration of population and local fishery size were found to be mainly responsible for the deterioration of water quality.

    Interactions between Anisus spirorbis (Planorbidae) and Galba truncatula (Lymnaeidae) in snail communities on sedimentary soils

    Show short summary

    Field and laboratory investigations were conducted to study competition between the planorbid Anisusspirorbis and the lymnaeid Galba truncatula when these two species live in bispecific communities on sedimentary soils. In presence of adult G. truncatula, the survival of juvenile and pre-adult planorbids significantly diminished while the number of egg-masses laid by adult planorbids showed a significant decrease.

    Are we heading towards a global decrease in coregonine catches?

    Show short summary

    Coregonine catches declined in 67% of the 27 lakes studied across three continents in the Northern Hemisphere during the first two decades of the 21st century, with 44% showing significant trends. The analysis showed that lakes with significant catch declines were larger and nutrient-poor. The rate of change in catch appeared to be related to the trophic state of the lake, with oligotrophic and ultra-oligotrophic lakes experiencing the largest declines. While local factors such as nutrients, invasive species and fishing practices contribute to declines, the study suggests a global link between trophic state and coregonine catch trends, influenced by climate change and lake size. The results highlight a potential conflict between water quality management objectives and coregonine fisheries productivity. Efforts to achieve pristine water conditions in developed countries may reduce the productivity of coregonine fisheries. The study highlights the need for collaboration between water and fisheries managers to establish lake-specific management objectives that address the needs of all lake users, particularly in the face of increasing climate change impacts and the introduction of invasive species.

  • What can fisheries managers learn from spatiotemporal assessment of freshwater fish populations in three Tunisian reservoirs: Lahjar, Kasseb and Siliana?

    Show short summary

    Spatiotemporal variation and stock assessment studies in Tunisian reservoirs revealed unbalanced status in Lahjar and Siliana, with high and low yields, respectively. Kasseb reservoir was found to be overexploited. These findings provide critical insights for improved management and conservation of these vital freshwater ecosystems.

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.

Spawning behaviour of lake whitefish in Lake Huron revealed by fine-scale acoustic telemetry and Indigenous ecological knowledge

Show short summary

In our study of the spawning behaviour of lake whitefish, we observed fish using a variety of habitat types during the spawning season, including a rocky spawning shoal, sandy substrates, and steeper slopes. Both sexes moved shallower at night and deeper during the day, with males moving more at night and females more during the day. This study could help inform stewardship efforts aimed at lake whitefish spawning habitat restoration and protection.

Characterization of testicular histology and spermatogenesis in the Levantine frog, Pelophylax bedriagae (Amphibia: Anura: Ranidae)

Show short summary

Amphibians are major members of aquatic and terrestrial ecosystems. They serve as both predator and prey in both ecosystems. Therefore, they provide the transfer of energy between these systems. However, there are few studies on the gametogenesis of amphibian. Therefore, histological characteristics of Pelophylax bedriagae testes were studied.

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.

Effects of salinity on species composition of zooplankton on Hau River, Mekong Delta, Vietnam

Show short summary

Zooplankton was found to change proportionally with salinity changes in the Mekong Delta (MD) estuarine areas. Rotifera and Cladocera were inversely proportional while Protozoa and Copepoda were positively proportional to salinity. This first time ever findings can be applied to predict change in biological productivity of the estuarine ecosystem in the MD.

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.
