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 ...

Periphyton as a key diet source of essential fatty acids for macroinvertebrates across a nutrient and dissolved organic carbon gradient in boreal lakes Vesterinen, Jussi; Strandberg, Ursula; Taipale, Sami J.; Kainz, Martin J.; Kankaala, Paula (Wiley; Association for the Sciences of Limnology and Oceanography, 2022)We studied how physiologically important long-chain polyunsaturated fatty acids (PUFA) in benthic macroinvertebrates (Asellus aquaticus, Chironomidae, and Oligochaeta) were related to those in periphyton and terrestrial ...
Impacts of piscicide-induced fish removal on resource use and trophic diversity of lake invertebrates Eloranta, Antti P.; Kjærstad, Gaute; Power, Michael; Lakka, Hanna-Kaisa; Arnekleiv, Jo Vegar; Finstad, Anders G. (Elsevier, 2022)Chemical eradication of non-native species has become a widely used method to mitigate the potential negative impacts of altered competitive or predatory dynamics on biodiversity and natural ecosystem processes. However, ...
Ruokonen, T. J.; Karjalainen, J. (Springer Science and Business Media LLC, 2022)Temperature is one of the most important factors governing the activity of ectothermic species, and it plays an important but less studied role in the manifestation of invasive species impacts. In this study, we investigated ...
