Summary, Etc. Note: |
Abstract: This key is the second in a series for identification of the helminths reported in waterfowl (Family Anatidae, Order Anseriformes). |
|
|
|
Abstract: The trematodes show the greatest variety of forms among the helminth parasites of waterfowl, including over half of all species reported; sometimes this group also includes the greatest part of the worms in a single bird. Over 500 species of trematodes have been reported in waterfowl and almost all of these have been included in the present set of keys, although it was not possible to obtain the descriptions of a few forms (7 out of 525). |
