| organochlorine residues and shell thicknesses in eggs of the clapper rail, common gallinule, purple gallinule, and limpkin (class aves), eastern and southern united states, 1972-74. | organochlorine residues and shell thicknesses were surveyed in eggs of the clapper rail (rallus longirostris), purple gallinule (porphyrula martinica), common gallinule (gallinula chloropas), and limpkin (aramus guarauna) from the eastern and southern united states. clapper rail eggs were collected during 1972-73 in new jersey, virginia, and south carolina. during 1973-74, gallinule eggs were collected in florida, south carolina, and louisiana, and limpkin eggs were collected in florida. egg con ... | 1980 | 6780971 |
| conspecific brood parasitism in the tropics: an experimental investigation of host responses in common moorhens and american purple gallinules. | species occupying a broad latitudinal range may show greater phenotypic plasticity in behavior than species with smaller ranges or more specific habitat requirements. this study investigates for the first time the occurrence of conspecific brood parasitism (cbp) in sympatric tropical populations of the common moorhen (gallinula chloropus pauxilla bangs) and the american purple gallinule (porphyrula martinica l.). cbp occurred in at least 20% (n = 76) of common moorhen nests on the rio chagres in ... | 2011 | 22393503 |
| conflict resolution of grammar and gender for avian species-group names under article 31.2.2 of the iczn code: is gender agreement worth it? | we analyze recent nomenclatural treatment of selected avian species-group names that may be either adjective and variable or noun and invariable. in 27 such names, we found that 14 previously identified as adjectives are nouns under article 31.2.2 of the international code of zoological nomenclature. five of them may require correction in current checklists; they are bresilius in ramphocelus bresilius (linnaeus, 1766) to bresilia, germana in amblyornis macgregoriae germana rothschild, 1910 to ge ... | 2016 | 27395618 |
| monitoring of pb exposure in waterfowl ten years after a mine spill through the use of noninvasive sampling. | lead exposure in waterfowl was studied using noninvasive fecal sampling in the guadalquivir marshes in spain, an area affected by the 1998 aznalcóllar mine disaster. feces of greylag geese (anser anser, n = 191) and purple gallinule (porphyrio porphyrio, n = 91) were collected from three different impacted sites (entremuros, caracoles and cerro de los ánsares) during the winters of 2004 to 2008. lead and aluminium (an indicator of sediment ingestion) and pb isotope signatures (to discriminate be ... | 2013 | 23437364 |
