Realized trophic niche of Echinogammarus veneris (Crust. Amphipoda), Proasellus coxalis (Crust. Isopoda) and Planorbis sp. (Gastropoda), reared in single and mixed laboratory plots was analysed utilizing the radiophosphorus (32P) as resources marker. The resource utilization rate of E. veneris is limited by co-occurrence. Co-occurrence leads to a shift in diet composition of the 2 Crustacea species, and leads to a restriction of E. veneris niche breadth. -from English summary

Abstract
Realized trophic niche of Echinogammarus veneris (Crust. Amphipoda), Proasellus coxalis (Crust. Isopoda) and Planorbis sp. (Gastropoda), reared in single and mixed laboratory plots was analysed utilizing the radiophosphorus (32P) as resources marker. The resource utilization rate of E. veneris is limited by co-occurrence. Co-occurrence leads to a shift in diet composition of the 2 Crustacea species, and leads to a restriction of E. veneris niche breadth. -from English summaryI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
