Stomach Nematodes of Wild Ducks (subfamily Anatinae) Wintering in the North-western Poland
نویسندگان
چکیده
The purpose of this study was to present the structure of nematofauna community with particular emphasis on stomach (proventriculus and gizzard) nematodes in wild ducks wintering in large numbers in the North-Western Poland. Hosts (n=152) were represented by 17 species from eight genera belonging to three different ecological tribes: Anatini, Aythyini, and Mergini. Parasitic nematodes (n=14,396) were found in the digestive tract of 813 out of 1,052 birds (77.3%), with the vast majority of nematodes (93.9%) found in the gizzard (n=7,326) and proventriculus (n=6,198). Nematodes isolated from these organs represented 21 species from six families: Amidostomatidae, Acuariidae, Tetrameridae, Dioctophymatidae, Ascarididae, and Anisakidae. The most prevalent were nematodes from the genus Amidostomoides (n=6,686 individuals; 49.4%), and the most dominant species was A. monodon (5,013 nematodes).

West Pomerania is located on the migratory route of many species of birds. Among them are many representatives of wild duck species (subfamily Anatinae), which are often the primary hosts of many helminths due to the fact of living in two different environments: terrestrial and aquatic.

The biliary bile acid composition of 10 anseriform and three flamingo species was determined using a variety of chromatographic techniques. Some bile samples contained an unusual 23-hydroxylated derivative of chenodeoxycholic acid, (23R)-3a,7a,23_trihydroxy-5P-cholan-24-oic acid (P-phocacholic acid). The proportion of this unusual bile acid correlated highly with the order of evolutionary appea...

Cloacotaenia megalops (Nitzsch in Creplin, 1892) is a polyxenic and cosmopolitan tapeworm from the family Hymenolepididae. Its generic name derives from their typical location (cloaca), and the typical final hosts which are birds typically associated with water and marsh environments: Anseriformes, Galliformes and Gruiformes. In Poland, the presence of C. megalops has been observed so far in 16...

While wild goose populations wintering in North America and Europe are mostly flourishing by exploiting farmland, those in China (which seem confined to natural wetlands) are generally declining. Telemetry devices were attached to 67 wintering wild geese of five different species at three important wetlands in the Yangtze River Floodplain (YRF), China to determine habitat use. 50 individuals of...
