Bibliography of American black duck (Anas rubripes) ecology and management
Migrations of the species in the area cited, feeding habits, available foods, and their utilization. Probably "through experimentation and management relatively unproductive stretches of marshland can be made to produce an abundance of desirable black duck foods." Addy, C. E. 1953. Fall migration of the black duck. 19:1-63. U.S. Fish and Wildlife Service Special Science Report Wildlife no. 19, ...
متن کاملHeteropatric speciation in a duck, Anas crecca.
Heteropatric differentiation is a mode of speciation with gene flow in which divergence occurs between lineages that are in sympatry and allopatry at different times during cyclic spatial movements. Empirical evidence suggests that heteropatric differentiation may prove to be common among seasonally migratory organisms. We examined genetic differentiation between the sedentary Aleutian Islands ...
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 کاملDescription of the mallard duck (Anas platyrhynchos) karyotype.
The karyotype of the mallard duck, Anas platyrhynchos, was characterised on the basis of R and C bands. Chromosomal preparations obtained from in vitro blood lymphocyte cultures were RBG- and CBG-stained. The structures of nine and 14 pairs of chromosomes were analysed by the RBG and CBG chromosome banding techniques, respectively. The location of R bands, as well as the size and arrangement of...
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...
