| new reports and a redescription of porrocaecum heteropterum (diesing, 1851) (ascarididae), a rare nematode parasitic in south american.threskiornithid birds1. | porrocaecum heteropterum (diesing, 1851) (nematoda, ascarididae) is reported parasitising the white-faced ibis plegadis chihi and the black-faced ibis theristicus melanopis melanopis (ciconiiformes, threskiornithidae) from the provinces of buenos aires and neuquén, argentina. this nematode has been reported very few times in the literature, mainly from brazilian threskiornithids, and there have been no new reports following a redescription of the species given in 1957. this paper provides new ho ... | 2001 | 11389327 |
| effects of contaminants on reproductive success of aquatic birds nesting at edwards air force base, california. | contamination by organochlorine pesticides (ocs), polychlorinated biphenyls, metals, and trace elements at edwards air force base (eafb), located in the mojave desert, could adversely affect nesting aquatic birds, especially at the sewage lagoons that comprise piute ponds. estimates of avian reproduction, in conjunction with analyses of eggs and avian foods for contaminant residues, may indicate the potential for negative effects on avian populations. from 1996 to 1999, we conducted studies at t ... | 2006 | 16998635 |
| evolutionary dynamics of hybridization and introgression following the recent colonization of glossy ibis (aves: plegadis falcinellus) into the new world. | geographic range shifts can cause secondary contact and hybridization between closely related species, revealing mechanisms of species formation and integrity. these dynamics typically play out in restricted geographic regions, but highly vagile species may experience major distributional changes resulting in broad areas of contact. the glossy ibis (plegadis falcinellus) is a dispersive waterbird of the old world and australia that colonized eastern north america in the early 19th century and ca ... | 2019 | 30614583 |

| 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 in egg concentrations between 1985 and 2000. about 45-63% of the earliest nesting segment shows reduce ... | 2010 | 19697124 |
| conspecific brood parasitism in the white-faced ibis plegadis chihi (aves: pelecaniformes) revealed by microsatellites' based kinship-reconstruction. | the white-faced ibis plegadis chihi vieillot, 1817 (pelecaniformes: threskiornithidae) is a socially monogamous colonially breeding bird in which behavioral and ecological observations suggest the occurrence of conspecific brood parasitism (cbp). we inferred aspects of the genetic mating system of p. chihi in nature, using a genetic approach in the absence of parental information. we used five heterologous microsatellite loci and a multiple-step methodological approach to infer kinship patterns ... | 2013 | 23554386 |
| neottialges (pelecanectes) ibisicola sp. n. (acari: hypoderidae) from the subcutaneous tissues of the white-faced ibis, plegadis chihi (ciconiiformes: threskiornithidae). | neottialges (pelecanectes) ibisicola sp. n. is described from the subcutaneous tissues of the white-faced ibis, plegadis chihi, from west texas. the new species is similar to n. (p.) plegadicola fain, but differs from this and other species of the subgenus by idiosomal chaetotaxy, presence of a bifurcate apical extension on tarsus iii, solenidion phi on tibia i less than 1/2 as long in the new species, lateroventral seta of tibia i whiplike, structure of the genital sclerite and suckers, and pre ... | 1979 | 512760 |
| polymorphic 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 alleles/locus). average he over all loci and colonies was 0.55, and the combined probability of excludi ... | 2012 | 22481877 |
| cutaneous pythiosis in a nestling white-faced ibis. | a nestling white-faced ibis (plegadis chihi) with multifocal skin ulcerations on the wings, neck, head, and limbs was found in a wetland agricultural region of the central valley in california. pathologic, microbiologic, and molecular findings were consistent with restricted, cutaneous infection by the oomycete pythium insidiosum. the microscopic features of the disease, including intense, necrotizing eosinophilic and granulomatous inflammation, are similar to those previously described in mamma ... | 2008 | 18587102 |
| tetrameres (gynaecophila) aspicula n. sp. (nematoda: tetrameridae), a proventricular parasite of the white-faced ibis plegadis chihi in argentina. | tetrameres (gynaecophila) aspicula n. sp. is described from the proventriculus of the white-faced ibis plegadis chihi (vieillot) (ciconiiformes, threskiornithidae) from argentina. the new species is characterised by the absence of spicules, by possessing two ventral rows of extremely small spines in males, extending along the second half of body length, and by the tiny, very feebly developed postcloacal papillae. t. (g.) aspicula n. sp. is compared to the remainder of the species in the subgenus ... | 2000 | 10966218 |
