The future distribution of river fishes will be jointly affected by climate and land use changes forcing species to move in space. However, little is known whether fish able keep pace with predicted use-driven habitat shifts, particular fragmented networks. In this study, we coupled models (stepwise boosted regression trees) 17 species-specific their dispersal (fish model FIDIMO) the European River Elbe catchment. We quantified (i) extent direction (up- vs. downstream) shifts under...
Abstract River ecosystems are threatened by future changes in land use and climatic conditions. However, little is known of the influence interactions these two dominant global drivers change on ecosystems. Does interaction amplify (synergistic interaction) or buffer (antagonistic impacts does their effect differ magnitude, direction spatial extent compared to single independent pressures. In this study, we model impact interacting effects climate distribution 33 fish species Elbe River. The...
Abstract The effects of invasive alien species (IAS) on host–affiliate relationships are often subtle and remain unnoticed or insufficiently quantified. global decline freshwater unionid mussel has been attributed to many causes, but little is known about the interactions IAS, with their complex life cycle, which includes an obligatory parasitic stage (the glochidium) that develops fishes. capacity a European mussel, Anodonta anatina , develop its widespread fish host, Squalius cephalus was...
Illicit drug abuse presents pervasive adverse consequences for human societies around the world. consumption also plays an unexpected role in contamination of aquatic ecosystems that receive wastewater discharges. Here, we show methamphetamine, considered as one most important global health threats, causes addiction and behavior alteration brown trout Salmo trutta at environmentally relevant concentrations (1 µg l-1). Altered movement preference methamphetamine during withdrawal were linked...
Most lotic ecosystems have been heavily modified in recent centuries to serve human needs, for example, by building dams form reservoirs. However, reservoirs major impacts on freshwater ecosystem functions and severely affect rheophilic fishes. The aim of this review is gather evidence that aside from direct habitat size reductions due reservoir construction, competition food space predation generalist fishes community compositions tributaries (river/stream not directly affected water...
The first telemetry study analysing behaviour of the largest freshwater predator in European rivers, Silurus glanis , was performed bimonthly during years 2002–2004. Movement juveniles and adults occurred mostly same time intervals. only statistical differences for nocturnal activity spring autumn. In winter, low with peaks daylight, autumn, maximal movement recorded dusk. summer, catfish were active across whole 24 h even high‐flow conditions. During all other seasons, inversely related to...
Summary Parasitic species can affect host behaviour in various ways. Freshwater mussels of the superfamily U nionoidea have a glochidia larva that is parasitic on fish. Our aim was to evaluate whether fish exposed distinct could upstream dispersal parasite. Many freshwater are highly endangered, and understanding relationships with their hosts important for conservation. However, research behavioural effects parasitism activity and/or mussel larvae nature has received little attention....
The Czech Republic has experienced a number of inter- and intra-continental introductions (42 introduced species total), with 29 historically confirmed 20 still present in the wild. Fourteen have become established, representing 27% current fish fauna. Pond aquaculture recreational fisheries are two major pathways introduction spread, they responsible for 80% 36% all fish, respectively. Over last decade, there been significant increase management practice stocking non-native particularly...
Abstract The pet trade is known to be one of the most important pathways aquatic non-native species introduction and Indonesia a significant partner. Popular ornamental South American river stingrays ( Potamotrygon spp.) were introduced in 1980s culture was established. Here we present detailed Indonesian market aquaculture survey, volume between January 2020 June 2022, list customer countries with total amount imported stingrays. Climate similarities native range P . motoro jabuti analysed....
Tramadol is a widely used analgesic with additional antidepressant and anxiolytic effects. This compound has been reported in continental waters reaching concentrations of µg/L as consequence its inefficient removal sewage treatment plants increasing use over time. In this study, European chubs (Squalius cephalus) were exposed to 1 tramadol water for 42 days subsequent 14 depuration. Our results revealed that underwent changes their behaviour compared the control group. The behavioural...
Physiological and behavioural constraints hinder albino individuals. Albino animals are rare in the wild; this trait is associated with easy detection by predators, non-native or damaged environments, exclusively aphotic environments total darkness. The social aspect of albinism reported only for human beings, effect distinguishable time space when benefits, used to a limited extent. Thus far, consequences remain unknown. We socially established groups pigmented catfish, (Silurus glanis),...
In addition to hypopigmentation of the skin and red iris colouration, albino animals also display distinct physiological behavioural alterations. However, information on social interactions is rare has mostly been limited specially bred strains rodents from unique environments in caves. Differentiating between effects albinism domestication behaviour can be difficult, cave fish changes according species-specific adaptations conditions permanent darkness. The agonistic behaviours offspring...
Seventeen individuals of ide Leuciscus idus were radio-tracked weekly from September 2003 to 2004 in the River Elbe, Czech Republic, examine migration patterns and influence environmental factors on their diurnal behaviour. Of 10 measured, L. significantly influenced by turbidity, which increased movement home range size species. The peak longitudinal occurred spring, indicating pre-spawning migration. Migrating fish moved downstream later returned upstream vicinity original locations,...
