a new species of sciadiocara skrjabin, 1916 (nematoda: acuariidae) parasitic in shorebirds in argentina.in the present paper we describe a new species of the genus sciadiocara from haematopus palliatus from the mar chiquita coastal lagoon (37 degrees 46' s, 57 degrees 27' w), argentina. we provide two host records (h. palliatus and larus dominicanus) for the genus, both from buenos aires province, argentina. s. haematopodi n. sp. closely resembles s. legendrei petter, 1967. the new species can be distinguished by the morphology of the distal end of the left spicule, the shorter length of the right ...199910613539
organochlorine residues in six species of estuarine birds, south carolina, 1971-75.in south carolina between 1971 and 1975, authors evaluated the occurrence of organochlorine residues in the laughing gull (larus atricilla), white ibis (eudocimus albus), glossy ibis (plegadis falcinellus), american oystercatcher (haematopus palliatus), willet (catoptrophorus semipalmatus), and ruddy turnstone (arenaria interpres). tissues of birds found dead and eggs were analyzed, eggshell thicknesses were measured, and incidental observations were made of reproductive success and population s ...1979117426
exceptionally high cd levels and other trace elements in eggshells of american oystercatcher (haematopus palliatus) from the bahía blanca estuary, argentina.concentrations of six trace metals were determined in the eggshells of american oystercatchers (haematopus palliatus) from the bahía blanca estuary, argentina. all metals measured in selected samples presented concentrations above the detection limit. means found for cu, pb, cr, zn and ni were as follow: 2.02±0.52, 7.23±2.33, 0.78±0.03, 2.22±1.13 and 6.05±0.89mg/kg dw. the mean concentrations of cd found were surprisingly high: 13.28±3.38mg/kg dw. previous studies made on prey items of the ameri ...201526362457
circulating fat-soluble vitamin concentrations and nutrient composition of aquatic prey eaten by american oystercatchers (haematopus palliatus palliatus) in the southeastern united states.the american oystercatcher (haematopus palliatus palliatus) is currently listed as a species of high concern by the united states shorebird conservation plan. because nutritional status directly impacts overall health and reproduction of individuals and populations, adequate management of a wildlife population requires intimate knowledge of a species' diet and nutrient requirements. fat-soluble vitamin concentrations in blood plasma obtained from american oystercatchers and proximate, vitamin, a ...201425843321
health assessment of american oystercatchers (haematopus palliatus palliatus) in georgia and south carolina.the american oystercatcher (haematopus palliatus palliatus) is the only species of oystercatcher native to the atlantic coast of north america and is restricted in distribution to intertidal shellfish beds in coastal areas. currently, the american oystercatcher population in south carolina and georgia is threatened by widespread habitat loss, resulting in low reproductive success and small population size. oystercatchers could be an important indicator of ecosystem health because they depend on ...201020688683
ornithodoros (alectorobius) capensis neumann (acari: ixodoidea: argasidae), a parasite of seabirds, established along the southeastern seacoast of the united states.ornithodoros (alectorobius) capensis neumann, an ectoparasite of seabirds found circumglobally in the tropics and subtropics, has become established along the southeastern seacoast of the united states. the tick has been found feeding primarily on brown pelicans, pelecanus occidentalis, but also has been found on the laughing gull, larus atricilla, and the american oystercatcher, haematopus palliatus. we report here the presence of o. (a.) capensis from new hanover and brunswick counties (near t ...19921495062
managing birds of conservation concern on sandy shores: how much room for future conservation actions is there?resource limitations often prevent the active management required to maintain habitat quality in protected areas. because restrictions in access or allowable public activities are the sole conservation measure in these locations, an important question to consider is whether species of conservation concern truly benefit from parcels that are shielded from human disturbance. here, we assess the conservation benefit of protecting birds from human recreation on over 204 km of sandy beaches by (a) es ...201830519421
hematological indices of injury to lightly oiled birds from the deepwater horizon oil spill.avian mortality events are common following large-scale oil spills. however, the sublethal effects of oil on birds exposed to light external oiling are not clearly understood. we found that american oystercatchers (area of potential impact n = 42, reference n = 21), black skimmers (area of potential impact n = 121, reference n = 88), brown pelicans (area of potential impact n = 91, reference n = 48), and great egrets (area of potential impact n = 57, reference n = 47) captured between 20 june 20 ...201829024020
optimizing conservation benefits for threatened beach fauna following severe natural disturbances.wildlife on sandy beaches is often constrained by transformation of natural areas for human use, and opportunities for acquiring or restoring new habitat are rare. storms can often force changes in land use naturally by re-shaping coastal landforms, thereby creating high quality habitat; yet, wildlife requirements are seldom considered in post-storm recovery planning, and conservation practitioners lack suitable evidence to argue for the protection of habitats freshly formed by storms. here we u ...201930176477
first record of debris ingestion by the shorebird american oystercatcher (haematopus palliatus) on the southern coast of brazil.plastic has become abundant in the oceans and proved to be a threat to marine and coastal fauna. in this study, we present the first record of synthetic debris ingested by the shorebird american oystercatcher (haematopus palliatus) in brazil. we collected 24 stomach contents from october 2007 to october 2015 and 58% were juveniles. synthetic materials were found in 100% of stomachs. used plastic fragments and plastic pellets were the most frequent items, beige and white were more common colors. ...201930660268
