The non-native invasive American blue crab Callinectes sapidus Rathbun 1896 is spreading across the Mediterranean Sea, endangering native communities, fisheries, and aquaculture. Yet, knowledge on its predation efficacy in the non-native range remains limited, and little is known about potential sex-specific differences in functional responses. This study presents the first functional response analysis of C. sapidus outside it...

Grasslands in temperate Europe are key biodiversity hotspots, supporting not only a rich vascular flora but also diverse communities of bryophytes and lichens. However, the processes shaping lichens and bryophytes in these ecosystems, particularly along environmental gradients, remain understudied. We investigated the relative roles of abiotic factors (elevation and rock abundance) and biotic drivers (vascular plant cover and...

Metal and metalloid (hereafter simply ‘metal’) pollution is a growing global concern for both aquatic organisms and human health. Fishes are important in human diet, but they can also accumulate metals in their tissues. Therefore, it is important to monitor the concentration of metals in their muscle, and to investigate potential patterns of bioaccumulation and biomagnification. Here, we studied the bioaccumulation and biomagn...

Winter is a challenge for fish in temperate regions as it is likely to create a bottleneck for small‐bodied fish due to starvation. Resource consumption could contribute substantially to the overwinter survival of fish. Nevertheless, fish feeding activity and related impacts at low temperatures are understudied. We assessed the hunting periodicity and functional response of a non‐native European brown bullhead Ameiurus nebulos...

We investigated the trophic ecology of three non-native crayfish species (the marbled crayfish Procambarus virginalis , the red swamp crayfish Procambarus clarkii and the spiny-cheek crayfish Faxonius limosus ) and two non-native fishes (the eastern mosquitofish Gambusia holbrooki and the three-spined stickleback Gasterosteus aculeatus ) from two sections of a thermal tributary of the Barát brook in Budapest (Hungary) over the...

The introduction of non‐native aquatic species has fundamentally transformed aquatic assemblages, primarily due to human activities, such as aquaculture, fisheries enhancement, aquarium trade, the creation of artificial corridors, and deliberate and accidental releases. Despite growing concern for biological invasions, there is no overall global appraisal of successful non‐native fishes. This study compiled a comprehensive dat...

Numerous phytosanitary threats challenge global agriculture, ecosystems, and food security. These threats are exacerbated by non-native species and diseases that are projected to intensify in the future due to global warming and anthropogenic habitat alterations. Assessments of the ecological impacts of overlooked phytosanitary threats are urgently needed under shifting environments. In this study, the potential effects of two...

Rising global food demands and technological advancements have led to unprecedented growth in the aquaculture industry. This rapid expansion has facilitated the translocation of species beyond their native ranges. While farming non‐native species boosts global food supply, it also poses environmental and socio‐economic risks when escapees establish in non‐native ecosystems. Using FAO data, we quantified and analysed global non...

Stable isotope analysis has been broadly used to study food webs, but often relies on inaccurate assumptions of trophic isotopic discriminations, which could lead to misinterpretation of obtained results. While many taxa exhibit similar trophic discrimination factors (TDFs), crayfish, exhibit omnivorous feeding strategies, yet TDFs are missing. In this study, we determined TDFs and tissue biokinetic parameters of the marbled c...
