Conditioning to magnetic direction in the Pekin duck (Anas platyrhynchos domestica).
The ability of ducks to derive magnetic direction information was tested in a conditioned procedure and the functional properties of the mechanism of magnetoreception investigated using common manipulations. Twelve ducks were trained to find a hidden imprinting stimulus behind one of three screens in a round arena. Once a criterion was reached, the directional choices of ducks were recorded in ...
متن کاملMalignant Melanoma in a Female Mallard Duck (Anas platyrhynchos)
Melanomas are malignant neoplasms originating from melanocytes. They reported in birds. In this case, macroscopic and microscopic (the histopathologic and IHC) findings supported a final diagnosis of cutaneous malignant melanoma in a mallard duck (Anas platyrhynchos). A female mallard duck (Anas platyrhynchos) was observed with a mass on the ventral portion of the neck. Th...
متن کاملVentilation changes associated with hatching and maturation of an endothermic phenotype in the Pekin duck, Anas platyrhynchos domestica.
Precocial birds begin embryonic life with an ectothermic metabolic phenotype and rapidly develop an endothermic phenotype after hatching. Switching to a high-energy, endothermic phenotype requires high-functioning respiratory and cardiovascular systems to deliver sufficient environmental oxygen to the tissues. We measured tidal volume (VT), breathing frequency (ƒ), minute ventilation (V̇e), and ...
متن کاملA genetic and cytogenetic map for the duck (Anas platyrhynchos).
A genetic linkage map for the duck (Anas platyrhynchos) was developed within a cross between two extreme Peking duck lines by linkage analysis of 155 polymorphic microsatellite markers, including 84 novel markers reported in this study. A total of 115 microsatellite markers were placed into 19 linkage groups. The sex-averaged map spans 1353.3 cM, with an average interval distance of 15.04 cM. T...
متن کاملEpithelial Diversification of Thyroid Gland in Kuttanad Duck (Anas platyrhynchos domesticus) - A Postnatal Study
The study was conducted on 104 female Kuttanad ducks from day-old to 24 weeks of age and the birds were selected randomly from a single hatch for the study. The thyroid glands were collected from eight birds in each group at fortnightly intervals. After recording the gross features, the material was fixed using different fixatives and then processed for histological studies. The paired thyroid ...
