Figure 4.

Nonmetric multidimensional scaling plot (NMDS plot, stress = 0.080) of prey species composition in pellets, feces, and fish samples of cormorants collected during breeding seasons 2012 and 2013 at Chiemsee and identified using either morphological (pellets) or molecular (all sample types) analysis. The standard ellipsoid of each sample type represents the variation (95% confidence region) in prey composition, that is, the smaller the area within the ellipsoid, the less variation in prey species co‐occurrence is found in the sample type. Fish taxa are labeled with abbreviations of their scientific name: Abrbra: Abramis brama, Albalb: Alburnus alburnus, Albmen: Alburnus mento, Albbip: Alburnoides bipunctatus, Angang: Anguilla anguilla, Barbar: Barbus barbus, Blibjo: Blicca bjoerkna, Carspp: Carassius spp., Chonas: Chondostroma nasus, Corspp: Coregonus spp., Cotgob: Cottus gobio, Cypcar: Cyprinus carpio, Esoluc: Esox lucius, Gymspp: Gymnocephalus spp., Lepgib: Lepomis gibbosus, Leuasp: Leuciscus aspius, Leuspp: Leuciscus spp., Lotlot: Lota lota, Oncmyk: Oncorhynchus mykiss, Perflu: Perca fluviatilis, Phopho: Phoxinus phoxinus, Rutrut: Rutilus rutilus, Rutvir: Rutilus virgo, Saltru: Salmo trutta, Sanluc: Sander lucioperca, Scaery: Scardinius erythrophthalmus, Siluri: Siluriformes, Squcep: Squalius cephalus, Thythy: Thymallus thymallus, Tintin: Tinca tinca, Vimvim: Vimba vimba
