Helminth Community Dynamics in Populations of Blue-Winged Teal (Anas discors) Using Two Distinct Migratory Corridors
Table 4
Numerical dominance values of species accounting for <1% of all helminths, and ND75 values, for the overall helminth community of blue-winged teal (Anas discors) and those delineated by host migratory corridor, age, and age within each migratory corridor.
