As poikilotherms, fish health is compromised by exposure to elevated temperatures (e.g. climate change-related warming, anthropogenic thermal pollution, and/or hatchery processes). While fish thermotolerance has been demonstrated to be plastic, the downstream impacts of early life-stage high temperature exposure are not known. In the present study,...

Freshwater mussels (Unionida) can strongly affect nutrient cycling in temperate ecosystems but data from the tropics is lacking. We quantified the effects of mussel filtration, excretion and biodeposition on nutrient and photosynthetic pigment concentrations in a tropical eutrophic lake and mesotrophic river, featuring one non-native and two native...

Acoustic barriers, which can deter fish from accessing hazardous areas, have the potential to protect valuable fish stocks. Previous studies have demonstrated that some prey fish species can detect and avoid their predators using sound cues. Such anti-predator responses may be used in acoustic barriers to hinder the movement of prey fish. In this s...

It was reported that the complex geological history of the southern Balkans caused diversification of terrestrial species. On the other hand, knowledge of the evolutionary history of freshwater biota is scarce. In order to contribute to an understanding of the historical biogeography of the region’s freshwaters, as well as to describe intraspecific...

The aim of this study was to determine microcrustacean secondary production (P/B) and a herbivory ratio (ZB:PB) in the River Danube and a floodplain lake to reveal models in plankton food web functioning. P/B was used to assess population variation under different environmental conditions, while ZB:PB provided information on the zooplankton grazing...

Freshwater mussels are a significant component of freshwater ecosystems and often make up the largest biomass within these systems. However, their habitat is often subject to impacts such as changes in water quality or hydraulic stressors related to dams. Using snorkelling surveys, this study identified the presence, relative abundance, and spatial...

The relationship between fish and amphibians is thought to be antagonistic because of the frequent amphibian extirpations after fish introductions, although some field observations show that amphibians and fish often co-occur in rivers. Here, we used surveys in north-eastern Spain (99,700 km2, 15 river catchments, N = 535 sites) to identify the mos...

Ecological naiveté or the failure to recognize a novel enemy is often put forward as a cause of extirpation of biodiversity in newly invaded systems. We tested the efficacy of a generalized antipredator defense, namely reduced activity level, in the tadpoles of Rhacophorus arboreus to the threat of the invasive predator red swamp crayfish Procambar...

Periphyton development is generally negatively influenced by eutrophication in shallow lakes and reservoirs. To better understand the nutrient enrichment effect on the periphyton and how the changes in seston may interfere in community responses, we performed an experiment with combined and isolated N and P addition during the enrichment and no-enr...

Three free-floating species that normally co-occur in the natural waters of southern China were studied—two globally introduced invasive species, Eichhornia crassipes and Pistia stratiotes, and a native counterpart, Hydrocharis dubia. The responses of the three species to different phosphorus and nitrogen levels were determined using root morpholog...
