“…Second, the relationship between Mg and total length was found to be significant for adult specimens. These observations could be due to ontogenetic differences in habitat use, behavior, and diet (Haubrock et al 2018(Haubrock et al , 2020(Haubrock et al , 2021b that are reflected in different metal accumulations (Balzani et al 2021). Indeed, I. punctatus juveniles live close to the riverbank and feed more on detritus, while adults live on the bottom and feed in the whole water column (Endo et al 2015;Haubrock et al 2020), possibly leading to Cr bioaccumulation in young individuals and a reduction with age in Mg concentrations in adults.…”

Metal pollution is one of the main environmental threats in freshwater ecosystems. Aquatic animals can accumulate these substances and transfer them across the food web, posing risks for both predators and humans. Accumulation patterns strongly vary depending on the location, species, and size (which in fish and crayfish is related to age) of individuals. Moreover, high metal concentrations can negatively affect animals’ health. To assess the intraspecific relationship between metal accumulation and size and health (proxied by the body condition) of individuals, the concentration of 14 metals (Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Ni, Pb, Se, Zn) was analyzed in six alien species from the highly anthropogenically altered Arno River (Central Italy): five fish (Alburnus alburnus, Pseudorasbora parva, Lepomis gibbosus, Ictalurus punctatus, and Silurus glanis) and one crayfish (Procambarus clarkii). We found that in P. clarkii, Cu was negatively related to size, as well as Al in L. gibbosus and Mg for adult I. punctatus. Positive size-dependent relationships were found for Hg in L. gibbosus, Fe in S. glanis, and Cr in juvenile I. punctatus. Only Co and Mg in S. glanis were found to negatively correlate with individual health. Since metal concentrations in animal tissue depend on trade-offs between uptake and excretion, the few significant results suggest different types of trade-offs across different species and age classes. However, only predatory fish species (L. gibbosus, I. punctatus, and S. glanis) presented significant relationships, suggesting that feeding habits are one of the primary drivers of metal accumulation.

“…Also, the seasonal variation in diet found in this study is in line with that reported from other populations (Xie et al, 2000; Yalçın‐Özdilek et al, 2013). This is not surprising, as P. parva is well known to show a wide trophic plasticity (Rolla et al, 2020), similar to other invasive fish (Haubrock, Balzani, Matsuzaki, et al, 2021) or taxa (Balzani, Vizzini, et al, 2021). Moreover, it is worth noting that the feeding activity tended to be very low in winter, when we found most of the digestive tracts to be empty (48%), as confirmed by the vacuity index.…”

The topmouth gudgeon Pseudorasbora parva is one of the worst invasive species worldwide and is considered to be highly plastic in terms of its phenotype but also behavioral ecology. Here, we analyzed the population structure and the morphological and dietary plasticity of four populations of P. parva across the four seasons within the Arno River basin in Central Italy. We found that the studied populations were morphologically different, suggesting multiple introductions or adaptation to different environmental conditions. In all populations, males were bigger and, overall, more frequent than females. The gonadosomatic index showed a similar pattern across all populations, with higher spring and summer values, indicating a long reproductive period. The diet of P. parva considerably varied across populations and seasons, suggesting a high degree of spatio-temporal trophic plasticity. Diet breadth varied among seasons, being more specialized in spring and summer and more opportunistic during autumn and winter. Our results highlight high trophic plasticity in the invasive populations of P. parva, potentially impacting multiple native taxa.

“…Studies in the mid-, to long-term phases after the accident include models using sum of exponential functions 13 , 16 , 17 and process-level diffusion models 11 , 18 , 19 . The two-component decay function model (TDM) 16 , 17 , which is the sum of two exponential functions, was used to fit the measured Cs activity concentration and showed good agreement with the measured values 6 , 10 , 12 . On the other hand, by using the diffusion models, Bulgakov et al 11 and Konoplev et al 18 , 19 succeeded in showing the temporal trend of radiocesium in the mid- and long-term phases after the accidents at Chernobyl and Fukushima.…”

“…At present, the activity concentration of Cs in river water is quite low 7 – 9 . However, in closed lakes, there is a problem of long-tailed temporal change in low-level radioactive contamination because the activity concentration declines steeply immediately after the accident, but then turns to a gradual decrease 6 , 10 . Such a problem is also observed in closed lakes and small lakes after the Chernobyl accident 11 , 12 .…”

The Fukushima Daiichi Nuclear Power Plant accident also contaminates lakes in Japan. Especially in closed lakes, there is a problem of prolonged low-level $$^{137}$$ 137 Cs contamination because the activity concentration of $$^{137}$$ 137 Cs declines sharply immediately after the accident, but then begins to decrease slowly. In this paper, we derived a long-term prediction formula based on the fractional diffusion model (FDM) for the temporal variation in $$^{137}$$ 137 Cs activity concentrations of the water in Lake Onuma on Mt. Akagi, one of the closed lakes, and of pond smelt (Hypomesus nipponensis), a typical fish species inhabiting in the lake. The formula reproduced well the measured $$^{137}$$ 137 Cs activity concentration of the lake water and pond smelt for 5.4 years after the accident. Next, we performed long-term prediction for 10,000 days using this formula and compared it with the prediction results of the two-component decay function model (TDM), which is the most common model. The results suggest that the FDM prediction will lead to a longer period of contamination with low-level $$^{137}$$ 137 Cs than the TDM prediction.
