“…The main difference came from dunlins which appeared to be discriminated by their high As concentrations. This trend was also found in the muscle ( Fig 2C) and corroborated by the elevated As and Se concentrations observed in dunlins and red knots ( Table 2; Lucia et al, 2012b). In the muscle, godwits were discriminated by important Cu, Fe, Hg and Zn concentrations.…”

“…It allowed however to differentiate the degree of bioaccumulation of species using potentially the same habitats: intertidal mudflats. First, red knots and dunlins were characterized by higher As concentrations in kidney but also in the liver for red knots, as previously pointed out by Lucia et al (2012b). Depending on the chemical form ingested, this essential element could trigger several adverse effects in birds (Eisler, 1994;Kunito et al, 2008).…”

“…Elevated Se concentrations also discriminated both species from redshanks and godwits, with however, red knots reaching twice the Se concentrations of dunlins in the liver and kidney (Lucia et al, 2012b). At high exposures, Se and Hg can each be individually toxic, but evidence supports that their co-accumulation reduces each other's toxic effects (Peterson et al, 2009).…”

International audienceThis study investigated the link between trace element concentrations and respective diets of two shorebird species present in the Pertuis Charentais, Atlantic coast of France: the Dunlin (Calidris alpina) and Redshank (Tringa totanus). Trace elements concentrations (Ag, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Zn) were investigated in the liver, kidney, muscle and feathers of 28 dunlins and 15 redshanks accidentally dead during catches by mist net. Analyses of carbon and nitrogen stable isotope ratios were carried out in liver, muscle and feathers to determine whether differences in diet explained the variations in elemental levels. These results were compared to previous data obtained on two other shorebird species present on the same sites: the Black-tailed Godwit (Limosa limosa) and Red Knot (Calidris canutus). This study demonstrated that shorebirds of the Pertuis Charentais were characterized by differential trace element bioaccumulation. Arsenic and Se concentrations were elevated in red knots and dunlins, whereas redshanks displayed higher Cd concentrations in internal tissues. These trace element bioaccumulation discrepancies could mainly come from divergences of trophic habits between shorebirds. Species with the highest trophic position displayed the highest Hg concentrations in the liver, muscle and feathers demonstrating therefore the biomagnification potential of this metal, as opposed to Cd and Pb. The same trend was observed in muscle and feathers for Se and only in feathers for As. These data highlighted the need to study several tissues to obtain a full comprehension of trace element exposure and pathways especially for long-distance migrating species using various habitats and sites

“…Sanderlings spend time foraging on the ocean beaches, semipalmated sandpipers sometimes forage on the salt marshes, and red knots mainly forage on the bay mudflats and beaches. Thus the differences in metal levels among species may indicate slightly different trophic levels, as has been found for shorebirds using mudflats along coastal France [ 36 , 37 ]. In the same species, trophic level could vary over two trophic levels indicating trophic plasticity [ 36 , 37 ].…”

Understanding temporal changes in contaminant levels in coastal environments requires comparing levels of contaminants from the same species from different time periods, particularly if species are declining. Several species of shorebirds migrating through Delaware Bay have declined from the 1980s to the present. To evaluate some contaminants as cause for the declines, we examine levels of mercury, lead, cadmium, arsenic, chromium and selenium in feathers of red knot (Calidris canutus, N = 46 individuals), semipalmated sandpiper (Calidris pusilla, N = 70) and sanderling (Calidris alba, N = 32) migrating through Delaware Bay, New Jersey, USA, from 1991 to 1992 (N = 40), 1995 (N = 28), and 2011–2012 (N = 80) to determine if levels have changed. We found: (1) arsenic, chromium, and lead increased in red knot and decreased in semipalmated sandpiper; (2) cadmium decreased in semipalmated sandpipers; (3) mercury decreased in red knot and sanderlings; (4) selenium decreased in red knot and increased in semipalmated sandpipers. In 2011/2012 there were significant interspecific differences for arsenic, mercury and selenium. Except for selenium, the element levels were well below levels reported for feathers of other species. The levels in feathers in red knots, sanderling, and semipalmated sandpipers from Delaware Bay in 2011/2012 were well below levels in feathers that are associated with effect levels, except for selenium. Selenium levels ranged from 3.0 µg·g−1 dry weight to 5.8 µg·g−1 (semipalmated sandpiper), within the range known to cause adverse effects, suggesting the need for further examination of selenium levels in birds. The levels of all elements were well below those reported for other marine species, except for selenium, which was near levels suggesting possible toxic effects.

“…This makes it possible to use them for studies correlating trace elements with individual body mass (Burger et al, 1993;Lucia et al, 2012). The goal of this study was to determine trace element levels of six metals in Buff-breasted Sandpiper and attempt to correlate them with birds body mass.…”

Cadmium, cobalt, chromium, copper, manganese, nickel, zinc and lead concentrations were detected in feathers of Buff-breasted Sandpipers (Calidris subruficollis) captured during the non-breeding season and analyzed with relationship to body mass. Of these metals tested for, only copper levels (2.28 µg/g) were positively correlated with bird body mass. Zinc levels showed higher concentration (67.97 µg/g) than the other metals, and cadmium levels showed the lowest concentration (0.14 µg/g). Trace element concentrations were below toxicity levels for all tested chemicals and we suggest that this probably reflects that essential elements are maintained there by normal homeostatic mechanism and that no excessive environmental exposure to these elements during migration or on the wintering area is suggested by these results.Keywords: Charadriiformes, contaminants, body mass, wintering area, shorebirds. Concentração de elementos-traço em maçarico-acanelado amostrados noParque Nacional da Lagoa do Peixe, Sul do Brasil ResumoAs concentrações de cádmio, cobalto, cromo, cobre, manganês, níquel, zinco e chumbo foram detectadas em penas de Maçarico-acanelado (Calidris subruficollis) capturados durante o período de invernada e analisados em relação a massa corporal. Destes metais analisados, somente os níveis de cobre (2,28 µg/g) foram correlacionados positivamente com a massa corporal dos indivíduos. Níveis de zinco apresentaram-se mais altos (67,97 µg/g) que outros metais e os níveis de cádmio apresentaram as menores concentrações (0,14 µg/g). As concentrações dos elementos-traços estão abaixo dos níveis de toxicidade em todos os testes químicos e sugerimos que isto provavelmente ocorre pela manutenção dos elementos essenciais através do mecanismo normal de homeostase e não reflete a exposição destes elementos durante a migração ou nas áreas de invernada.Palavras-chave: Charadriiformes, contaminação, massa corporal, área de invernada, aves costeiras.
