The Niche of the Gill Parasite Dactylogyrus banghami (Monogenea: Dactylogyridae) on Notropis stramineus (Pisces: Cyprinidae)

Distribution of the monogenean Dactylogyrus banghami on the gills of the fish Notropis stramineus (Cyprinidae) was described by calculation of mean relative positions and Levins' niche breadths on the linear spatial resource gradients gill filament length and gill arch length. Thirty fish with...

Description
Summary:	Distribution of the monogenean Dactylogyrus banghami on the gills of the fish Notropis stramineus (Cyprinidae) was described by calculation of mean relative positions and Levins' niche breadths on the linear spatial resource gradients gill filament length and gill arch length. Thirty fish with 276 worms were examined; only 1 of the fish had an additional gill parasite species (Trichodina sp). Worms were more broadly and evenly distributed across the length of the gill arch than they were on the filament (breadths of 0.91 and 0.67, respectively). Mean worm positions were near the center of both resources: 54% of the distance from the arch cartilage on the filament, and 54% from the ventral end of the arch itself. The results are considered consistent with predictions about the niche structures of species in unsaturated noninteractive specialist communities.
