Wintering area DDE source to migratory white-faced ibis revealed by satellite telemetry and prey sampling.
Locations of contaminant exposure for nesting migratory species are difficult to fully understand because of possible additional sources encountered during migration or on the wintering grounds. A portion of the migratory white-faced ibis (Plegadis chihi) nesting at Carson Lake, Nevada continues to be exposed to dichloro-diphenyldichloro-ethylene (DDE) with no change, which is unusual, observed...
متن کاملDigeneans and cestodes parasitic in the white-faced ibis Plegadis chihi (Aves: Threskiornithidae) from Argentina.
Some digeneans and cestodes parasitic in a population of the white-faced ibis Plegadis chihi (Vieillot) from Buenos Aires province, Argentina, are presented. The digeneans Dietziella egregia (Dietz, 1909), Patagifer bilobus (Rudolphi, 1819), Ascocotyle (Leighia) hadra Ostrowski de Nuñez, 1992 and Posthodiplostomum nanum Dubois, 1937 from the intestine; Prosthogonimus ovatus (Rudolphi, 1803) fro...
متن کاملEffect of color vision phenotype on the foraging of wild white-faced capuchins, Cebus capucinus
New World monkeys exhibit a color vision polymorphism. It results from allelic variation of the single-locus middle-to-long wavelength opsin gene on the X chromosome. Females that are heterozygous for the gene possess trichromatic vision. All other individuals possess dichromatic vision. The prevailing hypothesis for the maintenance of the color vision polymorphism is through a consistent fitne...
متن کاملPolymorphic heterologous microsatellite loci for population genetics studies of the white-faced ibis Plegadis chihi (Vieillot, 1817) (Pelecaniformes, Threskiornithidae)
We screened 44 heterologous microsatellites isolated in species of the families Threskiornithidae, Ciconiidae and Ardeidae for their use in a migratory waterbird, the white-faced ibis Plegadis chihi (Vieillot, 1817) (Threskiornithidae). Of the screened loci, 57% amplified successfully and 24% were polymorphic. In two breeding colonies from southern Brazil (N = 131) we detected 32 alleles (2-10 ...
