Diet and trophic niche of the invasive signal crayfish in the first invaded Italian stream ecosystem Ercoli, Fabio; Ghia, Daniela; Gruppuso, Laura; Fea, Gianluca; Bo, Tiziano; Ruokonen, Timo J. (Nature Publishing Group, 2021)The occurrence of the signal crayfish Pacifastacus leniusculus in the Valla Stream was the first established population of this invasive species recorded in an Italian stream ecosystem. We evaluated the seasonality of diet ...

Evidence of energy and nutrient transfer from invasive pink salmon (Oncorhynchus gorbuscha) spawners to juvenile Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in northern Norway Dunlop, Kathy; Eloranta, Antti P.; Schoen, Erik; Wipfli, Mark; Jensen, Jenny L.A.; Muladal, Rune; Christensen, Guttorm N. (Wiley-Blackwell, 2021)Recent large influxes of non‐native Pacific pink salmon (Oncorhynchus gorbuscha) to North European rivers have raised concern over their potential negative impacts on native salmonids and recipient ecosystems. The eggs and ...
An invasive species, Carassius gibelio, alters the native fish community through trophic niche competition Özdilek, Şükran Yalçın; Partal, Nurbanu; Jones, Roger (Springer International Publishing, 2019)Carbon and nitrogen stable isotope analyses were used to determine isotopic niche width of the invasive fish species Carassius gibelio to help assess the niche overlap and potential impact of this species on the native ...
Catastrophic effects of sand mining on macroinvertebrates in a large shallow lake with implications for management Zou, Wei; Tolonen, Kimmo; Zhu, Guangwei; Qin, Boqiang; Zhang, Yunling; Cao, Zhigang; Kai, Peng; Cai, Yongjiu; Gong, Zhijun (Elsevier, 2019)Sand mining is a human activity that is increasing in inland waters and has profound effects on entire aquatic ecosystems. However, current knowledge of the effects of sand mining on freshwater lake ecosystems remains ...
